Katherine Banwell:

What might an increase in symptoms mean? Does it mean that the disease is progressing or that maybe it’s time to change therapies?   

Dr. Pemmaraju:

Yeah, possibly. So, with all this objective evidence, there are different buckets of disease progression. And some of them are objective and obvious, rising spleen, increasing blasts, or leukemia cells in the peripheral blood. The start of transfusion dependency for either anemia or platelets that weren’t there before. Sometimes, there are obvious things that you can point to, but there are a couple of scenarios where it’s not as obvious. You just named one. One is increasing symptom burden profile. You see, sometimes you have to think about, is it the sequela of the treatment itself or is it disease progression?  

I’ll give an example. If you start on an Interferon product and the dose is too high, you may be feeling not so great from the interferon. But maybe in that case, a simple dose reduction was the answer, because then you’re still getting the anti-disease activity, less side effects and all that. So, I’ll answer your question by saying possibly, but it can’t be the whole story. So, increasing symptoms is a harbinger, it’s a red flag.

In the clinic, it means pause. Workup, is this a subject of the treatment itself? Is it because the disease is progressing? Do we need to do a restaging and workup, whether that means a bone marrow biopsy, whatever that means? Or again, let’s put that other in there. What about the other comorbidities? Do you have class one heart failure, that’s now class three and you’re retaining fluid? And that’s why you’re short of breath and you actually need an echo and a cardiologist and an evaluation of your diuresis. So, I think that’s important, but the key is don’t blow it off, right? So, increasing symptom in MPN is telling you something isn’t right, and we need to check it out.   

Katherine Banwell:

Right, and for the patient, tell your healthcare team about it.  

Dr. Pemmaraju:

Communicate always. I think what we see is people are so proper and so compassionate and so kind and collegial, and that’s beautiful. But actually in the MPNs and all these rare blood cancers where so little is known and so little is obvious, communication is the key.

Increased MPN Symptoms | What Does It Mean for Patients?


Transcript:

Katherine Banwell:

I’d like to move on to common MPN symptoms now. Let’s start with myelofibrosis. What are the symptoms associated with this particular MPN?  

Dr. Pemmaraju:

Excellent question. So, for the myelofibrosis, generally thought to be our most advanced of the MPNs, can be low risk, intermediate to high risk. We’ll focus our comments here on intermediate to high risk, the more advanced MF. This is important because not only what I’m going to tell you is sort of a subjective list of symptoms, but because of the work of my great friend, Ruben Mesa, who pioneered the MPN symptom burden, we’ve actually been able to, as he and I say, quantify the unquantifiable.  

So, take subjective information and turn it into objective. For example, we know that among the three MPNs, PV, ET, and MF, that fatigue is by far the most common symptom that our patients report. It’s a fatigue that’s more than the general feeling tired at the end of the day. It’s sometimes a wiped-out fatigue. Some of our patients will have pruritus or itching. Many of our patients will have early satiety, which means getting full too early because either the spleen is too big, decreasing the appetite. Bone pain and neuropathy can happen in our MF patients. Brain fog and decreased concentration, huge issue among a lot of our patients. And finally, because of the low blood counts, if a myelofibrosis patient is anemic, they can have those issues. So, fatigue, shortness of breath, even chest pain and palpitations. If the platelets are too low, or too high for that matter, bleeding or clotting.  

So, the problem with myelofibrosis, it ranges the gamut from the low-risk patients, who can be treated maybe even as a PV or ET observation or not as advanced treatment paradigm, all the way to intermediate high risk where patients are cachectic, losing weight, not feeling well, drenching night sweats. And all of these can be captured on not only the scoring systems but also the symptom burden scales. And to be honest with you, this is the majority of what our patients are feeling outside of the blood counts and outside of the objective information. So much so to the point, Katherine, where a patient can present with these symptoms solely, without ever having a blood count or a bone marrow or anything, and then it leads to the work of it.  

Katherine Banwell:

Oh, wow. Wow, fascinating – what about symptoms for polycythemia vera?   

Dr. Pemmaraju:

Yeah, so this is a great theme that you’ve got going here, which is know your body. If you know your body, then you’re able to tell what’s abnormal or normal. p. vera can be a bit more subtle.  

Oftentimes patients with p. vera can have a normal life expectancy and the longer term series in Europe show that it’s basically about the same life expectancy as the general population or slightly lower. But that doesn’t tell the whole story. Patients with p.  vera can have an unbelievable symptom burden, either from the hyperviscosity of the hematocrit, the blood level being too high or the cytokine storm, that I mentioned, that makes people feel not well. So fatigue, brain fog, feelings of sluggishness, feeling too full, those are common in p. vera.  

The treatments are aimed at trying to make that better. So, phlebotomy to bring the hematocrit down below 45 can make you feel a little bit lighter, a little bit better, decrease the brain fog. If you’re using either the standard treatments of Hydrea or interferon, and then, of course, the baby aspirin to prevent clots, heart attacks, stroke. The newer agents in p. vera include the ropeginterferon that we mentioned earlier, clinical trials, such as the PTG-300 that I’m a part of, that try to really keep the blood levels normal all the time.   

And so hopefully help to improve the quality of life, decrease the chance of having a clot, and also hopefully try to make patients feel better from these aspects.   

Katherine Banwell:

What about essential thrombocythemia or ET? 

Dr. Pemmaraju:

ET, again, just like PV, you can have a lot of patients who are either incidentally diagnosed or not too much of a symptom burden. But again, here, the blood counts don’t tell the story. You can have “low risk ET” which is defined as less than 60 or no prior blood clots. So, you can be 43 years old, diagnosed with ET, your blood counts aren’t that high, but yet you’re still feeling overwhelming fatigue, itching. You’re seeing flashing things in your eyes called scotomas. You’re having small nerve or vascular issues called erythromelalgias. It’s a very elusive and difficult disease, particularly for our young patients. So, in ET, again, the same set of symptoms can happen. This fatigue, itching, the brain fog, concentration, bleeding, and or clotting.  

And so again, the goal of therapy is to mitigate those. If you’re young, a lot of patients are either observed or baby aspirin. If you’re older than 60 or have high risk features, then again, cytoreductive therapy. The other aspect I should mention is you can start out with one of these, and it transforms into the other. That’s called clinical or phenotypic shifts. You can start out as an ET, go to PV. You can start out as PV and go to myelofibrosis. You can start out as myelofibrosis and go to acute myeloid leukemia. So, that’s why follow-up, even over years, decades, is important, preferably with an expert team, because you never know when one of these things wants to transform. And then your side effect, or I should say your symptom profile therefore changes with that transformation.

Transcript:

Katherine Banwell:

What are the most common issues associated with the main MPN treatment classes? Let’s start with JAK inhibitors.  

Dr. Pemmaraju:

Oh, very nice. Yeah, that’s exactly the way I think about it too. So, with our JAK inhibitors, we now have 10 years since the approval of the ruxolitinib  (Jakafi), the first in class. And now we have two more approved agents which are known as fedratinib (Inrebic) and pacritinib (Vonjo), and hopefully a fourth agent, momelotinib (Ojjaara), which is under regulatory review at this time.  

[Editor’s Note: Momelotinib (Ojjaara) was approved by the U.S. Food and Drug Administration (FDA) on Sept 15, 2023 for the treatment of intermediate- or high-risk myelofibrosis, in adults with anemia.] 

So, we have a whole class of drugs. They have some similarities and then some differences, but in general, the JAK inhibitor class are well-tolerated drugs, but each of them has some side effects.  

I’d like to go through them just as a top-line overview. It’s very important. Number one for the ruxolitinib agent, the one that’s been around longest. This one is usually well-tolerated as we said, but you do have to look out for a few things. Non-melanoma skin cancers can be increased in some of our patients, so the importance of dermatology and skin evaluations. Some infections such as viral herpes, zoster, and shingles, so we need to be aware of that. And then weight gain, weight gain is something that we’re seeing more over time as we appreciate the drug, particularly as we move it into earlier lines of therapy, such as p. vera.

As I look at the other agents, the fedratinib already carries an FDA black box warning for an encephalopathy syndrome, thought to be Wernicke’s encephalopathy, which can affect the brain. But really an encephalopathy syndrome, which means we have to check thiamine levels and replace them and be aware of that. That’s vitamin B1 and also GI side effects with that agent. And then finally, the pacritinib agent has a few toxicity and side effects.  

Again, all these are on the package label insert, well-known. Some GI side effects, particularly in the first few months, including diarrhea, and we need to watch out for bleeding and these kinds of effects, especially in the opening days and weeks of the agent. So, again, JAK inhibitors, well-tolerated class, oral medicines, but can have some notable side effects that we have to follow together in the clinic.  

Katherine Banwell:

What about interferon? What are some common side effects?  

Dr. Pemmaraju:

Yeah, great. So, the interferon class, which actually now is a class of drugs. We started out as let’s call it the regular interferon, which was multiple times a week dosing. Then the pegylated interferon, which went down to once a week. And then now we have the ropeginterferon (Besremi), which is the recently approved agent in p. vera, which is every two weeks spaced out to every month.  

So, as you said, in this class of drugs, what’s old is new again. These drugs have actually been around longer than the JAK inhibitors, interestingly. You do have to be mindful. These are a very serious set of drugs. We usually set aside a good amount of time to talk about the side effects, and they are many historically.  

The main ones include psychiatric neurological side effects. So, it can cause a depressed mood, change in the mood, even depression. Hugely important, so everyone needs to be aware of that, including the caregivers. It can cause autoimmune side effects, so such as thyroid, liver, these type of side effects. And then finally, of course, any of these interferons can cause a flu-like profile, you know, not feeling well, particularly in the beginning days. So, we usually try to mitigate it with lots of education to the patient, the caregiver, remind all members of the team.

If you can, maybe even start at a low dose and escalate up, which is what we’re trying to do in the clinic. And then really close monitoring for stuff that you can monitor, the thyroid, the liver, the mental side effects, as we said. Usually most of our patients over time, most of them do get used to the drug. So, there is some kind of an immune component to it, but you can have side effects at any time.  

I would say also, Katherine, that these later forms of the interferon continue to improve. And so we’re seeing either less and less side effects or at least better managed, better tolerated, more understanding of these. So, a great class of drugs. And I should also say that our colleagues around the world are starting to combine the two classes of drugs for patients with myelofibrosis. And so we need to be paying attention to those combinatorial approaches. 

Katherine Banwell:

What about Hydrea (hydroxyurea)?   

Dr. Pemmaraju:

Yeah, so hydroxyurea, we also have to mention that.  

One of the workhorse medicines of our field. We use it in all the MPNs.  

Again, an older class of drugs such as the Interferons that have been around prior to the JAK inhibitors. Used in a variety of diseases, both benign and malignant, used in sickle cell anemia. Historically has been used in both blood and solid tumor cancers, but we use it very commonly in MPNs. Almost all of our viewers are familiar. Hydroxyurea is not a benign drug. It is a chemotherapeutic agent. You know, you have to handle it with care.  

And so it’s got a few side effects. It can cause some fatigue in some patients. One of the more notable classical side effects is an ulcer formation, either in the mouth area or in the lower extremities, such is in the feet, so, you know, grossly visible. It can cause some fever and not feeling well in some patients. I will say again, a lot of these drugs are generally well-tolerated. Most of our patients are 60, 70, 80, and older, but you can certainly have those side effects. A lot of these drugs, Katherine, can affect the skin.  

I did mention that earlier. So, ruxolitinib, even the interferons, hydrea, they can all cause skin lesions, maybe some of them associated with non-melanoma skin cancer, such as squamous cell and basal cell. So, one amazing part of the practice has been close association with our dermatology colleagues, not something I would have expected 10, 15 years ago. And that’s been a helpful part of the practice.  

So, I think it’s a point where I can emphasize that, in addition to having us as the MPN or blood cancer team, Katherine, the pandemic has reminded us the importance of primary care team as well. So, it’s really two teams, someone checking the cholesterol, cancer screenings, skin checkups, mammogram, PSAs. And then in coordination with your MPN team and then everyone working together, so colonoscopies, et cetera. So, just a plug there, especially the last three, four years where people have gotten behind to make sure that we’re keeping up with that part of the deal as well.   

Katherine Banwell:

With all the testing, yeah.  

Dr. Pemmaraju:

Exactly, right.  

Katherine Banwell:

You mentioned a couple of treatment side effects and how they’re managed, but in general, across the board, are treatment side effects managed in the same way, in similar ways?  

Dr. Pemmaraju:

Now, that’s a great question. So, here I’ve given you this nice list, kind of academic version of the list, but boy, no, right. And all my patients and everyone out there knows that there’s some varied practices. You know, the varied practices are not only, as you say, across the country and across the world, but also even in our own clinics, patient to patient. The MPNs have humbled and taught us that one person’s MPN can be starkly different from the next, so on and so forth. So, I’m not just talking about the difference between PV, ET, myelofibrosis, and systemic mastocytosis. I’m talking about one person’s MF is completely different than the other. I think there are a couple of things I didn’t mention. So, pruritus, or itching is one of the great symptoms really. It’s not a side effect usually, but it’s a symptom of the MPN. There are some ways to treat that in the clinic.  

Fatigue really has no great way to treat it. Usually when you introduce one of the JAK inhibitors that can improve. On the side effects side, as we were mentioning, a lot of these are unsatisfying things. The flu-like symptoms of the interferon, the weight gain of the JAK inhibitor. So, I think what you’re saying is so correct, and let me admit it, I’m going to be the first to admit it, there’s not really a good standard playbook.  

But on the other hand, I think personalization. As we’ve always said, in our rare disease space, if you have a disease, it’s not rare to you. It’s what you have, it’s what your spouse is dealing with, your loved one, your mother with you. And so, I would advocate here that there’s a personalized playbook there. I would say that there are three guiding principles though. One is when you have side effects of a medicine, the first thing to do is let your healthcare provider team know. I know that sounds obvious, but here I am in the clinic and sometimes we don’t find out until later. And so some of that is because the patient says to themselves, let’s tough it out. Or they may not know, or they may not be able to, or it may not be easy to communicate with our healthcare teams.

Two is when you’re evaluating, every patient’s case is different. This is not specific advice, as you said, at the top of the hour here. But in a general sense, you really need to evaluate if the side effect is peculiar or particular to just that patient case, so idiosyncratic, unpredictable, notable. 

Or, is it a general expected sort of something that you thought could already happen and then go with it from there? And then finally, the concept of dose interruptions, dose reductions, treatment holidays, something very important. So, basically a lot of different ways you can go, but no standard or uniform playbook in our MPN field, as you and the team well knows.

Katherine Banwell:

Hello and welcome. I’m your host, Katherine Banwell. Today’s program is a continuation of our Thrive Series and we’re going to discuss coping with MPN symptoms and managing treatment side effects. Before we get into the discussion, please remember that this program is not a substitute for seeking medical advice. Please refer to your healthcare team about what might be best for you.  

Let’s meet our guest today. Joining me is Dr. Naveen Pemmaraju. Dr. Pemmaraju, welcome. Would you please introduce yourself?  

Dr. Pemmaraju:

Oh, thank you, Katherine and team. Just an honor to be here. 

I’m Naveen Pemmaraju, a professor of leukemia at MD Anderson Cancer Center in Houston. And I also serve as one of our executive directors for the MD Anderson Cancer Network, and I specialize in MPNs and rare leukemia. So, happy to join you once again, Katherine.   

Katherine Banwell:

Thank you so much for being with us today, taking time out of your schedule. Well, Dr. Pemmaraju, when it comes to living and thriving within an MPN, managing disease symptoms and treatment side effects is a big part of that. How can symptoms and side effects impact life with an MPN?  

Dr. Pemmaraju:

Katherine, I’m glad you asked about that because I think before we get into the science and the pathobiology and all these complex things, it really starts with the patient. And as you and your team and others have really noted, the MPN for many of our patients, it is a chronic, often lifelong journey. And we really need to reemphasize in this modern era, the patient-centered experience and the caregiver experience.  

And so I would emphasize a few things. One is that our MPNs are oftentimes so-called invisible diseases to other people. So, this phrase that just really is tough for us to hear for our patients and our loved ones, oh, you don’t look that you’re sick. You don’t look like you have cancer. So, it emphasizes the internal part of the internal medicine, that’s one. Number two, it reminds you that you cannot tell on the external what kind of a war, a cytokine war that is going on inside of a patient. And so even though the blood counts are normal, the spleen is okay, the treatment paradigm is going okay, we don’t know what’s really going on. So, that’s why our great friend and colleague Ruben Mesa invented and pioneered the MPN symptom burden to really nail down what’s going on.  

And then third is our treatments, Katherine, our treatments, while overall halting or stopping or helping the MPN can then introduce a whole other round of toxicity, side effects, and so we need to manage that.  

So, both the disease itself and the treatments, two separate entities, and that’s what we need to be monitoring in the clinic.  

Katherine Banwell:

All right, well, thank you for that. As we get into the discussion, Dr. Pemmaraju, it’s important to note that some of the issues we’ll be talking about today are symptoms of the MPN, and others may be treatment-related side effects. So, let’s start with side effects. What are the most common issues associated with the main MPN treatment classes? Let’s start with JAK inhibitors.   

Dr. Pemmaraju:

Oh, very nice. Yeah, that’s exactly the way I think about it too. So, with our JAK inhibitors, we now have 10 years since the approval of the ruxolitinib, the first in class. And now we have two more approved agents which are known as fedratinib (Inrebic) and pacritinib (Vonjo), and hopefully a fourth agent, momelotinib, which is under regulatory review at this time.

It’s what you have, it’s what your spouse is dealing with, your loved one, your mother with you. And so, I would advocate here that there’s a personalized playbook there. I would say that there are three guiding principles though. One is when you have side effects of a medicine, the first thing to do is let your healthcare provider team know. I know that sounds obvious, but here I am in the clinic and sometimes we don’t find out until later.

And so some of that is because the patient says to themselves, let’s tough it out. Or they may not know, or they may not be able to, or it may not be easy to communicate with our healthcare teams. Two is when you’re evaluating, every patient’s case is different. This is not specific advice, as you said, at the top of the hour here. But in a general sense, you really need to evaluate if the side effect is peculiar or particular to just that patient case, so idiosyncratic, unpredictable, notable. 

Or, is it a general expected sort of something that you thought could already happen and then go with it from there? And then finally, the concept of dose interruptions, dose reductions, treatment holidays, something very important. So, basically a lot of different ways you can go, but no standard or uniform playbook in our MPN field, as you and the team well knows.  

Katherine Banwell:

Thank you for that Dr. Pemmaraju. I’d like to move on to common MPN symptoms now. Let’s start with myelofibrosis. What are the symptoms associated with this particular MPN?  

Dr. Pemmaraju:

Excellent question. So, for the myelofibrosis, generally thought to be our most advanced of the MPNs, can be low risk, intermediate to high risk. We’ll focus our comments here on intermediate to high risk, the more advanced MF. This is important because not only what I’m going to tell you is sort of a subjective list of symptoms, but because of the work of my great friend, Ruben Mesa, who pioneered the MPN symptom burden, we’ve actually been able to, as he and I say, quantify the unquantifiable.  

So, take subjective information and turn it into objective. For example, we know that among the three MPNs, PV, ET, and MF, that fatigue is by far the most common symptom that our patients report. It’s a fatigue that’s more than the general feeling tired at the end of the day. It’s sometimes a wiped-out fatigue. Some of our patients will have pruritus or itching. Many of our patients will have early satiety, which means getting full too early because either the spleen is too big, decreasing the appetite. Bone pain and neuropathy can happen in our MF patients. Brain fog and decreased concentration, huge issue among a lot of our patients.

And finally, because of the low blood counts, if a myelofibrosis patient is anemic, they can have those issues. So, fatigue, shortness of breath, even chest pain and palpitations. If the platelets are too low, or too high for that matter, bleeding or clotting.  

So, the problem with myelofibrosis, it ranges the gamut from the low-risk patients, who can be treated maybe even as a PV or ET observation or not as advanced treatment paradigm, all the way to intermediate high risk where patients are cachectic, losing weight, not feeling well, drenching night sweats. And all of these can be captured on not only the scoring systems but also the symptom burden scales. And to be honest with you, this is the majority of what our patients are feeling outside of the blood counts and outside of the objective information. So much so to the point, Katherine, where a patient can present with these symptoms solely, without ever having a blood count or a bone marrow or anything, and then it leads to the work of it.   

Katherine Banwell:

Oh, wow. Wow, fascinating. What about symptoms for polycythemia vera?  

Dr. Pemmaraju:

Yeah, so this is a great theme that you’ve got going here, which is know your body. If you know your body, then you’re able to tell what’s abnormal or normal. p. vera can be a bit more subtle.  

Oftentimes patients with p. vera can have a normal life expectancy and the longer term series in Europe show that it’s basically about the same life expectancy as the general population or slightly lower. But that doesn’t tell the whole story. Patients with p.  vera can have an unbelievable symptom burden, either from the hyperviscosity of the hematocrit, the blood level being too high or the cytokine storm, that I mentioned, that makes people feel not well. So fatigue, brain fog, feelings of sluggishness, feeling too full, those are common in p. vera.  

The treatments are aimed at trying to make that better. So, phlebotomy to bring the hematocrit down below 45 can make you feel a little bit lighter, a little bit better, decrease the brain fog. If you’re using either the standard treatments of hydrea or Interferon, and then, of course, the baby aspirin to prevent clots, heart attacks, stroke. The newer agents in p. vera include the ropeginterferon that we mentioned earlier, clinical trials, such as the PTG-300 that I’m a part of, that try to really keep the blood levels normal all the time.  

And so hopefully help to improve the quality of life, decrease the chance of having a clot, and also hopefully try to make patients feel better from these aspects.  

Katherine Banwell:

What about essential thrombocythemia or ET? 

Dr. Pemmaraju:

ET, again, just like PV, you can have a lot of patients who are either incidentally diagnosed or not too much of a symptom burden. But again, here, the blood counts don’t tell the story. You can have “low risk ET” which is defined as less than 60 or no prior blood clots. So, you can be 43 years old, diagnosed with ET, your blood counts aren’t that high, but yet you’re still feeling overwhelming fatigue, itching. You’re seeing flashing things in your eyes called scotomas. You’re having small nerve or vascular issues called erythromelalgias. It’s a very elusive and difficult disease, particularly for our young patients. So, in ET, again, the same set of symptoms can happen. This fatigue, itching, the brain fog, concentration, bleeding, and or clotting.  

And so again, the goal of therapy is to mitigate those. If you’re young, a lot of patients are either observed or baby aspirin. If you’re older than 60 or have high risk features, then again, cytoreductive therapy. The other aspect I should mention is you can start out with one of these and it transforms into the other. That’s called clinical or phenotypic shifts. You can start out as an ET, go to PV. You can start out as PV and go to myelofibrosis. You can start out as myelofibrosis and go to acute myeloid leukemia. So, that’s why follow-up, even over years, decades, is important, preferably with an expert team, because you never know when one of these things wants to transform. And then your side effect, or I should say your symptom profile therefore changes with that transformation.  

Katherine Banwell:

Well, it’s obvious that there’s some symptom overlap along with this.  

Dr. Pemmaraju:

Right. 

Katherine Banwell:

And so I’m wondering what the strategies are for managing these. Let’s start with fatigue first.  

Dr. Pemmaraju:

Let’s do that.  

Katherine Banwell:

How do you manage that?  

Dr. Pemmaraju:

This is one of the tougher parts of what we do. I’m glad you’re pinning me down to say it because really this is the majority of what we need to be talking about in the clinic. I’m going  to just be honest, you know, with all the scientific breakthroughs and everything, some of these are limited. The fatigue, this is some of the strategies I use and some of the experts in the field. I think one is managing the underlying disease. So, as you mentioned, if you have high-risk, intermediate to high-risk myelofibrosis, one of the great findings of our field is the JAK inhibitor class generally helps to improve symptom burden.  

So, that is the splenomegaly, the fatigue, the pruritus. Maybe not so much the itching, but some of these other things. So, I think treating the underlying disease, that’s okay. Number two is many clinics, Onc centers around the country are starting to open up a supportive care or fatigue center clinic. So, I am referring several of my patients there, we’re talking about diet, nutrition, exercise. We used to never talk about these things. Ruben Mesa has found that doing yoga and meditation can genuinely actually help the pathobiology to reduce the cytokine storm and improve the fatigue and quality of life. 

Dr. Angela Fleischman, our colleague at UC Irvine, has done work suggesting that possibly an antioxidant diet such as the Mediterranean diet can help the overall general fatigue, well-being, wellness. And then of course I mentioned earlier, but I’ll mention here too, sometimes fatigue is outside of the MPN. Have you had your TSH or thyroid checked? What about your vitamin D levels? How are you doing on these PCP general checks? Things that may be contributing to the life and the happiness.

And finally, let me make a plug for mental health. I don’t know how much we were emphasizing before the COVID pandemic, but after, the last three or four years have been tough. Healthcare providers, caregivers, patients themselves, mental health checkup, that can also be contributing to fatigue, not getting out of bed, in addition to the organic medical problems. So, let me advocate a multifactorial approach, scientifically summed up as treating what you can with the underlying MPN, fine, treating the side effects and symptoms of the MPN, as you said. 

And then, other, which can be a huge bucket, particularly as we get older, to not forget about that. Again, checking the thyroid level. And then when you’re on these different treatments, you can personalize it. Interferon, obviously, has its own separate set of side effects and then of course the other agents. So, I think that may be the best way to approach it. Maybe a three-bucket approach. The MPN itself, and then the treatment itself, and then the other, something like that.  

Katherine Banwell:

Yeah, yeah. And as you’ve mentioned, it’s all going to be personalized and individualized, because what’s going to work for one person is not necessarily going to work for another.  

Dr. Pemmaraju:

Hear, hear, well said to that. You know, you think you make a great diagnosis in the clinic, someone’s having fatigue, they’re on therapy for your MPN. You check the TSH, it’s wildly abnormal. Okay, you refer them to endocrine. Six months later, the thyroid level is completely normal now on thyroid medicine. And yet, the fatigue, brain fog, everything is still not clear.  

The MPN is under good control. What gives? That’s the difficult part of these diseases. So, I really love what you said about the personalization and to keep looking and keep trying.   

Katherine Banwell:

What might an increase in symptoms mean? Does it mean that the disease is progressing or that maybe it’s time to change therapies?   

Dr. Pemmaraju:

Yeah, possibly. So, with all this objective evidence, there’s different buckets of disease progression. And some of them are objective and obvious, rising spleen, increasing blasts, or leukemia cells in the peripheral blood. The start of transfusion dependency for either anemia or platelets that weren’t there before. Sometimes, there are obvious things that you can point to, but there are a couple of scenarios where it’s not as obvious. You just named one. One is increasing symptom burden profile. You see, sometimes you have to think about, is it the sequela of the treatment itself or is it disease progression?  

I’ll give an example. If you start on an Interferon product and the dose is too high, you may be feeling not so great from the Interferon. But maybe in that case, a simple dose reduction was the answer because then you’re still getting the anti-disease activity, less side effects and all that. So, I’ll answer your question by saying possibly, but it can’t be the whole story. So, increasing symptoms is a harbinger, it’s a red flag. In the clinic, it means pause. Workup, is this a subject of the treatment itself? Is it because the disease is progressing? Do we need to do a restaging and workup, whether that means a bone marrow biopsy, whatever that means?

Or again, let’s put that other in there. What about the other comorbidities? Do you have class one heart failure, that’s now class three and you’re retaining fluid? And that’s why you’re short of breath and you actually need an echo and a cardiologist and an evaluation of your diuresis. So, I think that’s important, but the key is don’t blow it off, right? So, increasing symptom in MPN is telling you something isn’t right, and we need to check it out.  

Katherine Banwell:

Right, and for the patient, tell your healthcare team about it.  

Dr. Pemmaraju:

Communicate always. I think what we see is people are so proper and so compassionate and so kind and collegial, and that’s beautiful. But actually in the MPNs and all these rare blood cancers where so little is known and so little is obvious, communication is the key.  

Katherine Banwell:

Yeah. I’d like to make some time now to answer questions from the audience.  

Dr. Pemmaraju:

Great. 

Katherine Banwell:

And here are a few we received prior to the program. Stephanie writes, I have ET and I’m not being treated. Do you have advice for the watch and wait period? I’m anxious about the disease changing and don’t know what I’m waiting for. So, before you answer the question, Dr. Pemmaraju, would you define this term, watch and wait?  

Dr. Pemmaraju:

I will. And to Stephanie and everyone out there, this is a great question. I will say half the folks I talk to actually call it watch and worry, okay. Some people call it watch and wait, and as Stephanie’s saying, some people call it watch and worry.   

Yeah, the concept is threefold. One is that there are many cancers, many cancers, including blood cancers, that can be caught so early on that they don’t require treatment. A lot of patients with CLL, chronic lymphocytic leukemia, ET, as Stephanie mentioned, in the solid tumor. It’s very common to be diagnosed with a prostate cancer that’s low grade, early stage that can be observed. Number two is in ET, there is a science behind it.   

What we found in our studies, and they can be updated over time and you’ll see those, the traditional is that if you’re below the age of 60 and/or you’ve had no blood clot, thrombotic event, that’s considered low risk. And the treatment can be observation, perhaps adding in a baby aspirin to prevent against blood clots if there’s no contraindication. Now what’s magic about that age 60, obviously as you know, it’s not magic. It’s more of a statistical, continuous variable algorithm that says around that time, the risk of blood clots goes up. And so then you’d consider cytoreductive therapy at that point. Now there’s exceptions to that.

Many of our young patients are on therapy, but there’s usually some reason for that. Some high-risk feature, wildly uncontrolled blood counts, for example, symptom burden, some other high-risk features. So, it’s a suggestion. It’s a guideline, not an absolute. And then the third part of it is, the what do you do in that time? And that’s the frustrating thing. And I think that’s what Stephanie’s getting to.  

Again, that’s why I said the watch and worry versus watch and wait. Some of it is, how are you feeling outside of this? Some patients take it as a great news. Hey, you have this blood cancer, that’s not good news. But the good news is it’s probably not going to be active for a long time, we can, “just watch it.” But some people, as Stephanie is saying, take it the opposite way. What do you mean I got a blood cancer? I got something lurking in my body. You’re telling me it’s there, you know it’s there. And so what’s up with that? And the concept there is that some of these situations like low-risk ET, we found that if you treat too early, too aggressively, you can actually do harm.  

Katherine Banwell:

Oh. 

Dr. Pemmaraju:

So, that’s the key. These chemo drugs are not benign as you had me discuss earlier. They have toxicity, side effects, short-term, long-term. So, it’s a risk-benefit thing. If the risk far outweighs the benefit, as in the younger patient with no symptoms, no high-risk features, observation is okay. But at some point, when it turns, that’s the threshold.  

So, really the key is, if we believe these are stem cell blood cancer disorders, we need to be thinking about and designing therapies with minimal to no toxicity. Something that actually modifies the disease early on and something that leads to long-term outcomes. And we don’t have that yet in ET. We’re working on that in PV and myelofibrosis. So, stay tuned for that. And then finally, let me also add, this is an important point, not everybody gets it. This watch and wait versus watch and worry. So, I’m glad Stephanie brought that up because it’s not always good news, uniformly, when you tell someone, good news is you don’t have to do anything bad news, there’s something there.  

Katherine Banwell:

Right. Jess wrote in with this question. I’ve been experiencing bone pain and neuropathy. Is there anything that can eliminate or reduce these symptoms?  

Dr. Pemmaraju:

Great question, and it ties into our earlier question about the MPN symptom burden. On the original MPN-10 scale that Ruben and others pioneered, you will see both of those. You will see the bone pain, neuropathy.  

Now there’s been, you know, different narrowing down of these questionnaires and things, but in general, our patients do have these and that’s across the board. So, not only myelofibrosis but also our patients with PV and ET. These are among the most frustrating, I would say. Again, as you would expect, if you are advanced enough and you’re getting treatment, you hope that the treatment itself, whether it’s the Interferon or the JAK inhibitors or whatever you’re doing, clinical trial, hopes to alleviate those. But it doesn’t all the time.

Then the second issue is, these are likely the result of a cytokine storm or increased cytokines, these protein messengers that are abnormally high in our patients with MPNs. There’s varying unsatisfying things that people do. Sometimes we give antihistamines for people with bone pain. So that’s these over-the-counter sinus allergy medicines. Interestingly, the Claritins and the Zyrtecs, these type of medications, that can sometimes help in MPN bone pain. And then also for the neuropathy, these common neuropathy drugs that everybody knows, the gabapentins and all of these drugs are used frequently.  

There’s no doubt in my clinic and everybody else’s, but the varying levels of success. So, I think it speaks to the fact that these two are kind of from the MPN itself. And treating the underlying MPN is still usually your best strategy, using these, borrowing these medications, from the other aspects.

And then finally, my other plug here, which has kind of been a theme here, hopefully it resonates, and it doesn’t sound generic or unnecessary, is these things can sometimes be something else. Okay, bone pain and neuropathy can be something else. So, we do have cases of people having frequent falls, really serious stuff. In those cases, I refer those patients to a neurologist. Nerve conduction studies right, very advanced studies in the couple of cases that are so severe that it’s beyond thinking that it’s just due to the MPN.   

Katherine Banwell:

Dr. Pemmaraju, as a researcher, what are new and emerging therapies on the horizon in MPN care?  

Dr. Pemmaraju:

Well, Katherine, I’m glad you asked because I’m proud to tell you here, at the end of 2023, that we’ve now entered a new golden era of therapies for MPNs. Your group, and others, have led the way in advocating, but for so many years, honestly, we didn’t have many breakthroughs or new medicines. And now we literally have something we’re hearing about once a month. I think this golden era is divided into four buckets, Katherine, and that’s why I’m so excited for our patients and their caregivers.

Number one is novel JAK inhibitors. So, beyond the approved ruxolitinib, fedratinib, and now pacritinib, we have a fourth one that’s under consideration, that’s called momelotinib. Hopefully, we’ll have that approved by the end of the year. And there are actually other drugs around the world. So, not just in the U.S. and North America that are being developed as a further JAK inhibitor. So, just like we’ve seen in CML with the TKIs for BCR-ABL after the imatinib Gleevec medicine, hopefully, we have seven to 10 choices for our patients.  

Number two is the combinatorial approach of a JAK inhibitor plus something else. And that’s a field that I’m personally very involved in and helping to lead. The concept there is you take the known workhorse drug, the JAK inhibitor, use it as the backbone, and then add in the second agent. We started to do those studies in patients who were already starting to lose a response and we added in the second agent, those were called suboptimal studies.

And then now we’re moving those drugs into the frontline setting in international global randomized studies. So, stay tuned, let’s see how those go. But the concept is, can you take a new agent, whether it’s a BET inhibitor, a bromodomain inhibitor, a Bcl-xL inhibitor, PI3 Kinase, et cetera, and combine it with the JAK inhibitor? The third bucket that’s even more exciting to many people is that of novel agents standing alone by themselves. Now you’ve had either a JAK inhibitor or some other therapy for your myelofibrosis. That didn’t work for whatever reason. Now you’re looking for a completely new strategy.  

An explosion of research, not just in the lab, which we’ve had for the last 10 years, but over the last three or four years, amazingly, even despite the COVID pandemic. I would say dozens, really dozens of trials that are what you would consider beyond or non-JAK inhibitor therapy. Some of them include telomerase inhibition, with the imetelstat agent, for example. And so the concept here is, can you now hit the myelofibrosis in a completely different pathway?

And the answer clearly is yes. And those results have been tested now in the lower stages, the earlier stages, phase one and two. And you’re starting to see those drugs enter into the phase two and phase three. We eagerly await those results if there can be a viable beyond JAK inhibitor. And then finally, if that wasn’t exciting enough, there’s a fourth bucket, which is thinking about specifically the anemia myelofibrosis. We’ve never really historically done that. We’ve had older drugs, danazol, steroids, growth factor shots, blood transfusions.  

But now here you see both pharmaceutical interest, as well as academic interest, in developing agents that either specifically target the anemia of MF or both, the MF and the anemia. And that could be a game changer for our patients in the next five years. So, Katherine, a wealth of exploding research that I’m personally very excited about that gives me and our field hope, momentum, and enthusiasm going into 2024.   

Katherine Banwell:

Yeah. Well, Dr. Pemmaraju, as we close out our conversation, I wanted to end with a question that we usually start within our Thrive Series. In your experience, what does it mean to thrive with an MPN?  

Dr. Pemmaraju:

Well, I really love that phrase so much because it’s meaningful to me.  

You know, you’re talking about something that resonates with me and my patients, which is not just living with the MPN, but you’re talking about thriving with an MPN. That’s so resonant to us. I think really, I would go for three parts to that.  

One is that it’s an acknowledgment or a complete understanding of the disease. So, not denial, the opposite of denial, whatever that is, Katherine. So, understanding as much as you can about the disease which is, I encourage people to Google, look up on the internet. I just, what I want you to do is couple that with talking about it in context with your provider. I think the worry that people have is you’re at your home midnight, you’re Googling stuff, it may or may not be right.

So, anyway, so just do that, but then bring the information to the next visit. So, fully understanding and learning as much as you can in your own way. Number two is to be able to have a quality of life that is not just living with the disease, but actually being successful at your relationships, your work, whatever it is that brings you meaning and joy in life. And that sometimes has to do with the MPN paradigm, sometimes has to do with the other stuff we said.  

But I think, doing that, not despite the fact that you have the MPN, but acknowledging it with that, right? And then I think the third aspect is, if you have some way or some platform to be able to express yourself with the MPN because it’s such a rare disease, we think maybe only four out of 100,000 people worldwide get these. A lot of patients, not for everybody, by the way, but a lot of patients are thriving on support groups. 

It used to be you have to be in person, that’s very difficult to do with rare diseases. But now online, social media, a lot of different ways to get involved. Whether someone’s an introvert or an extrovert, whether someone wants to be private or public, all those things are hugely important, so it’s a personal decision. But for many, they want to get out there, and it’s not necessarily this scientific information exchange, although that’s good. But the support and encouragement and comradery of talking to other patients about what we’re talking about.  

It is, in fact, a little bit more facile to do it with the more common diseases, breast cancer, all of these things. And it’s much more difficult, social media online has opened that up. So, to me, I think that’s a kind of mix that I’ve been seeing in my patients. And that leads to empowerment. It leads to taking control of the things that can be controlled, leaving the things that can’t be controlled to what needs to happen. And then an understanding and anticipation of things that may happen in the next few visits, in the next few years. I think that’s how people can thrive with these MPNs. 

Katherine Banwell:

Yeah. And that’s a hopeful message to leave our audience with Dr. Pemmaraju. Thank you so much for joining us today.  

Dr. Pemmaraju:

Well, thank you, Katherine, and hats off to you and the team for not only keeping the advocacy and information going but during this pandemic time, becoming an essential source of information for our patients and getting the word out there. So, thank you.

Katherine Banwell:

Hello and welcome. I’m your host, Katherine Banwell. Today’s program is a continuation of our Thrive Series and we’re going to discuss coping with MPN symptoms and managing treatment side effects. Before we get into the discussion, please remember that this program is not a substitute for seeking medical advice. Please refer to your healthcare team about what might be best for you.  

Let’s meet our guest today. Joining me is Dr. Naveen Pemmaraju. Dr. Pemmaraju, welcome. Would you please introduce yourself?  

Dr. Pemmaraju:

Oh, thank you, Katherine and team. Just an honor to be here. 

I’m Naveen Pemmaraju, a professor of leukemia at MD Anderson Cancer Center in Houston. And I also serve as one of our executive directors for the MD Anderson Cancer Network, and I specialize in MPNs and rare leukemia. So, happy to join you once again, Katherine.   

Katherine Banwell:

Thank you so much for being with us today, taking time out of your schedule. Well, Dr. Pemmaraju, when it comes to living and thriving within an MPN, managing disease symptoms and treatment side effects is a big part of that. How can symptoms and side effects impact life with an MPN?  

Dr. Pemmaraju:

Katherine, I’m glad you asked about that because I think before we get into the science and the pathobiology and all these complex things, it really starts with the patient. And as you and your team and others have really noted, the MPN for many of our patients, it is a chronic, often lifelong journey. And we really need to reemphasize in this modern era, the patient-centered experience and the caregiver experience.  

And so I would emphasize a few things. One is that our MPNs are oftentimes so-called invisible diseases to other people. So, this phrase that just really is tough for us to hear for our patients and our loved ones, oh, you don’t look that you’re sick. You don’t look like you have cancer. So, it emphasizes the internal part of the internal medicine, that’s one. Number two, it reminds you that you cannot tell on the external what kind of a war, a cytokine war that is going on inside of a patient. And so even though the blood counts are normal, the spleen is okay, the treatment paradigm is going okay, we don’t know what’s really going on. So, that’s why our great friend and colleague Ruben Mesa invented and pioneered the MPN symptom burden to really nail down what’s going on.  

And then third is our treatments, Katherine, our treatments, while overall halting or stopping or helping the MPN can then introduce a whole other round of toxicity, side effects, and so we need to manage that.  

So, both the disease itself and the treatments, two separate entities, and that’s what we need to be monitoring in the clinic.  

Katherine Banwell:

All right, well, thank you for that. As we get into the discussion, Dr. Pemmaraju, it’s important to note that some of the issues we’ll be talking about today are symptoms of the MPN, and others may be treatment-related side effects. So, let’s start with side effects. What are the most common issues associated with the main MPN treatment classes? Let’s start with JAK inhibitors.   

Dr. Pemmaraju:

Oh, very nice. Yeah, that’s exactly the way I think about it too. So, with our JAK inhibitors, we now have 10 years since the approval of the ruxolitinib, the first in class. And now we have two more approved agents which are known as fedratinib (Inrebic) and pacritinib (Vonjo), and hopefully a fourth agent, momelotinib, which is under regulatory review at this time.  

[Editor’s Note: Momelotinib (Ojjaara) was approved by the U.S. Food and Drug Administration (FDA) on Sept 15, 2023 for the treatment of intermediate- or high-risk myelofibrosis, in adults with anemia.]

So, we have a whole class of drugs. They have some similarities and then some differences, but in general, the JAK inhibitor class are well-tolerated drugs, but each of them has some side effects.   

I’d like to go through them just as a top-line overview. It’s very important. Number one for the ruxolitinib agent, the one that’s been around longest. This one is usually well-tolerated as we said, but you do have to look out for a few things. Non-melanoma skin cancers can be increased in some of our patients, so the importance of dermatology and skin evaluations. Some infections such as viral herpes, zoster, and shingles, so we need to be aware of that. And then weight gain, weight gain is something that we’re seeing more over time as we appreciate the drug, particularly as we move it into earlier lines of therapy, such as p.- vera.

As I look at the other agents, the fedratinib already carries an FDA black box warning for an encephalopathy syndrome, thought to be Wernicke’s encephalopathy, which can affect the brain. But really an encephalopathy syndrome, which means we have to check thiamine levels and replace them and be aware of that. That’s vitamin B1 and also GI side effects with that agent. And then finally, the pacritinib agent has a few toxicity and side effects.  

Again, all these are on the package label insert, well-known. Some GI side effects, particularly in the first few months, including diarrhea, and we need to watch out for bleeding and these kinds of effects, especially in the opening days and weeks of the agent. So, again, JAK inhibitors, well-tolerated class, oral medicines, but can have some notable side effects that we have to follow together in the clinic.  

Katherine Banwell:

What about interferon? What are some common side effects?  

Dr. Pemmaraju:

Yeah, great. So, the interferon class, which actually now is a class of drugs. We started out as let’s call it the regular Interferon, which was multiple times a week dosing. Then the Pegylated Interferon, which went down to once a week. And then now we have the ropeginterferon (Besremi), which is the recently approved agent in p. vera, which is every two weeks spaced out to every month.  

So, as you said, in this class of drugs, what’s old is new again. These drugs have actually been around longer than the JAK inhibitors, interestingly. You do have to be mindful. These are a very serious set of drugs. We usually set aside a good amount of time to talk about the side effects, and they are many historically.  

The main ones include psychiatric neurological side effects. So, it can cause a depressed mood, change in the mood, even depression. Hugely important, so everyone needs to be aware of that, including the caregivers. It can cause autoimmune side effects, so such as thyroid, liver, these type of side effects. And then finally, of course, any of these Interferons can cause a flu-like profile, you know, not feeling well, particularly in the beginning days.

So, we usually try to mitigate it with lots of education to the patient, the caregiver, remind all members of the team. If you can, maybe even start at a low dose and escalate up, which is what we’re trying to do in the clinic. And then really close monitoring for stuff that you can monitor, the thyroid, the liver, the mental side effects, as we said. Usually most of our patients over time, most of them do get used to the drug. So, there is some kind of an immune component to it, but you can have side effects at any time.  

I would say also, Katherine, that these later forms of the Interferon continue to improve. And so we’re seeing either less and less side effects or at least better managed, better tolerated, more understanding of these. So, a great class of drugs. And I should also say that our colleagues around the world are starting to combine the two classes of drugs for patients with myelofibrosis. And so we need to be paying attention to those combinatorial approaches. 

Katherine Banwell:

What about hydrea 

Dr. Pemmaraju:

Yeah, right. Yeah, so hydroxyurea, we also have to mention that.  

One of the workhorse medicines of our field. We use it in all the MPNs.  

Again, an older class of drugs such as the Interferons that have been around prior to the JAK inhibitors. Used in a variety of diseases, both benign and malignant, used in sickle cell anemia. Historically has been used in both blood and solid tumor cancers, but we use it very commonly in MPNs. Almost all of our viewers are familiar. Hydroxyurea is not a benign drug. It is a chemotherapeutic agent. You know, you have to handle it with care.  

And so it’s got a few side effects. It can cause some fatigue in some patients. One of the more notable classical side effects is an ulcer formation, either in the mouth area or in the lower extremities, such is in the feet, so, you know, grossly visible. It can cause some fever and not feeling well in some patients. I will say again, a lot of these drugs are generally well tolerated. Most of our patients are 60, 70, 80, and older, but you can certainly have those side effects. A lot of these drugs, Katherine, can affect the skin.  

I did mention that earlier. So, ruxolitinib, even the interferons, hydrea, they can all cause skin lesions, maybe some of them associated with non-melanoma skin cancer, such as squamous cell and basal cell. So, one amazing part of the practice has been close association with our dermatology colleagues, not something I would have expected 10, 15 years ago. And that’s been a helpful part of the practice.   

So, I think it’s a point where I can emphasize that, in addition to having us as the MPN or blood cancer team, Katherine, the pandemic has reminded us the importance of primary care team as well. So, it’s really two teams, someone checking the cholesterol, cancer screenings, skin checkups, mammogram, PSAs. And then in coordination with your MPN team and then everyone working together, so colonoscopies, et cetera. So, just a plug there, especially the last three, four years where people have gotten behind to make sure that we’re keeping up with that part of the deal as well.  

Katherine Banwell:

With all the testing, yeah.  

Dr. Pemmaraju:

Exactly, right.  

Katherine Banwell:

You mentioned a couple of treatment side effects and how they’re managed, but in general, across the board, are treatment side effects managed in the same way, in similar ways?  

Dr. Pemmaraju:

Now, that’s a great question. So, here I’ve given you this nice list, kind of academic version of the list, but boy, no, right. And all my patients and everyone out there knows that there’s some varied practices. You know, the varied practices are not only, as you say, across the country and across the world, but also even in our own clinics, patient to patient. The MPNs have humbled and taught us that one person’s MPN can be starkly different from the next, so on and so forth.

So, I’m not just talking about the difference between PV, ET, myelofibrosis, and systemic mastocytosis. I’m talking about one person’s MF is completely different than the other. I think there are a couple of things I didn’t mention. So, pruritus, or itching is one of the great symptoms really. It’s not a side effect usually, but it’s a symptom of the MPN. There are some ways to treat that in the clinic.  

Fatigue really has no great way to treat it. Usually when you introduce one of the JAK inhibitors that can improve. On the side effects side, as we were mentioning, a lot of these are unsatisfying things. The flu-like symptoms of the interferon, the weight gain of the JAK inhibitor. So, I think what you’re saying is so correct, and let me admit it, I’m going to be the first to admit it, there’s not really a good standard playbook.  

But on the other hand, I think personalization. As we’ve always said, in our rare disease space, if you have a disease, it’s not rare to you. It’s what you have, it’s what your spouse is dealing with, your loved one, your mother with you. And so, I would advocate here that there’s a personalized playbook there. I would say that there are three guiding principles though. One is when you have side effects of a medicine, the first thing to do is let your healthcare provider team know. I know that sounds obvious, but here I am in the clinic and sometimes we don’t find out until later.

And so some of that is because the patient says to themselves, let’s tough it out. Or they may not know, or they may not be able to, or it may not be easy to communicate with our healthcare teams. Two is when you’re evaluating, every patient’s case is different. This is not specific advice, as you said, at the top of the hour here. But in a general sense, you really need to evaluate if the side effect is peculiar or particular to just that patient case, so idiosyncratic, unpredictable, notable. 

Or, is it a general expected sort of something that you thought could already happen and then go with it from there? And then finally, the concept of dose interruptions, dose reductions, treatment holidays, something very important. So, basically a lot of different ways you can go, but no standard or uniform playbook in our MPN field, as you and the team well knows.  

Katherine Banwell:

Thank you for that Dr. Pemmaraju. I’d like to move on to common MPN symptoms now. Let’s start with myelofibrosis. What are the symptoms associated with this particular MPN?  

Dr. Pemmaraju:

Excellent question. So, for the myelofibrosis, generally thought to be our most advanced of the MPNs, can be low risk, intermediate to high risk. We’ll focus our comments here on intermediate to high risk, the more advanced MF. This is important because not only what I’m going to tell you is sort of a subjective list of symptoms, but because of the work of my great friend, Ruben Mesa, who pioneered the MPN symptom burden, we’ve actually been able to, as he and I say, quantify the unquantifiable.  

So, take subjective information and turn it into objective. For example, we know that among the three MPNs, PV, ET, and MF, that fatigue is by far the most common symptom that our patients report. It’s a fatigue that’s more than the general feeling tired at the end of the day. It’s sometimes a wiped-out fatigue. Some of our patients will have pruritus or itching. Many of our patients will have early satiety, which means getting full too early because either the spleen is too big, decreasing the appetite. Bone pain and neuropathy can happen in our MF patients. Brain fog and decreased concentration, huge issue among a lot of our patients.

And finally, because of the low blood counts, if a myelofibrosis patient is anemic, they can have those issues. So, fatigue, shortness of breath, even chest pain and palpitations. If the platelets are too low, or too high for that matter, bleeding or clotting.  

So, the problem with myelofibrosis, it ranges the gamut from the low-risk patients, who can be treated maybe even as a PV or ET observation or not as advanced treatment paradigm, all the way to intermediate high risk where patients are cachectic, losing weight, not feeling well, drenching night sweats. And all of these can be captured on not only the scoring systems but also the symptom burden scales. And to be honest with you, this is the majority of what our patients are feeling outside of the blood counts and outside of the objective information. So much so to the point, Katherine, where a patient can present with these symptoms solely, without ever having a blood count or a bone marrow or anything, and then it leads to the work of it.   

Katherine Banwell:

Oh, wow. Wow, fascinating. What about symptoms for polycythemia vera?  

Dr. Pemmaraju:

Yeah, so this is a great theme that you’ve got going here, which is know your body. If you know your body, then you’re able to tell what’s abnormal or normal. p. vera can be a bit more subtle.  

Oftentimes patients with p. vera can have a normal life expectancy and the longer term series in Europe show that it’s basically about the same life expectancy as the general population or slightly lower. But that doesn’t tell the whole story. Patients with p.  vera can have an unbelievable symptom burden, either from the hyperviscosity of the hematocrit, the blood level being too high or the cytokine storm, that I mentioned, that makes people feel not well. So fatigue, brain fog, feelings of sluggishness, feeling too full, those are common in p. vera.  

The treatments are aimed at trying to make that better. So, phlebotomy to bring the hematocrit down below 45 can make you feel a little bit lighter, a little bit better, decrease the brain fog. If you’re using either the standard treatments of hydrea or Interferon, and then, of course, the baby aspirin to prevent clots, heart attacks, stroke. The newer agents in p. vera include the ropeginterferon that we mentioned earlier, clinical trials, such as the PTG-300 that I’m a part of, that try to really keep the blood levels normal all the time.  

And so hopefully help to improve the quality of life, decrease the chance of having a clot, and also hopefully try to make patients feel better from these aspects.  

Katherine Banwell:

What about essential thrombocythemia or ET? 

Dr. Pemmaraju:

ET, again, just like PV, you can have a lot of patients who are either incidentally diagnosed or not too much of a symptom burden. But again, here, the blood counts don’t tell the story. You can have “low risk ET” which is defined as less than 60 or no prior blood clots. So, you can be 43 years old, diagnosed with ET, your blood counts aren’t that high, but yet you’re still feeling overwhelming fatigue, itching. You’re seeing flashing things in your eyes called scotomas. You’re having small nerve or vascular issues called erythromelalgias. It’s a very elusive and difficult disease, particularly for our young patients. So, in ET, again, the same set of symptoms can happen. This fatigue, itching, the brain fog, concentration, bleeding, and or clotting.  

And so again, the goal of therapy is to mitigate those. If you’re young, a lot of patients are either observed or baby aspirin. If you’re older than 60 or have high risk features, then again, cytoreductive therapy. The other aspect I should mention is you can start out with one of these and it transforms into the other. That’s called clinical or phenotypic shifts. You can start out as an ET, go to PV. You can start out as PV and go to myelofibrosis. You can start out as myelofibrosis and go to acute myeloid leukemia. So, that’s why follow-up, even over years, decades, is important, preferably with an expert team, because you never know when one of these things wants to transform. And then your side effect, or I should say your symptom profile therefore changes with that transformation.  

Katherine Banwell:

Well, it’s obvious that there’s some symptom overlap along with this.  

Dr. Pemmaraju:

Right. 

Katherine Banwell:

And so I’m wondering what the strategies are for managing these. Let’s start with fatigue first.  

Dr. Pemmaraju:

Let’s do that.  

Katherine Banwell:

How do you manage that?  

Dr. Pemmaraju:

This is one of the tougher parts of what we do. I’m glad you’re pinning me down to say it because really this is the majority of what we need to be talking about in the clinic. I’m going  to just be honest, you know, with all the scientific breakthroughs and everything, some of these are limited. The fatigue, this is some of the strategies I use and some of the experts in the field. I think one is managing the underlying disease. So, as you mentioned, if you have high-risk, intermediate to high-risk myelofibrosis, one of the great findings of our field is the JAK inhibitor class generally helps to improve symptom burden.  

So, that is the splenomegaly, the fatigue, the pruritus. Maybe not so much the itching, but some of these other things. So, I think treating the underlying disease, that’s okay. Number two is many clinics, Onc centers around the country are starting to open up a supportive care or fatigue center clinic. So, I am referring several of my patients there, we’re talking about diet, nutrition, exercise. We used to never talk about these things. Ruben Mesa has found that doing yoga and meditation can genuinely actually help the pathobiology to reduce the cytokine storm and improve the fatigue and quality of life. 

Dr. Angela Fleischman, our colleague at UC Irvine, has done work suggesting that possibly an antioxidant diet such as the Mediterranean diet can help the overall general fatigue, well-being, wellness. And then of course I mentioned earlier, but I’ll mention here too, sometimes fatigue is outside of the MPN. Have you had your TSH or thyroid checked? What about your vitamin D levels? How are you doing on these PCP general checks? Things that may be contributing to the life and the happiness.

And finally, let me make a plug for mental health. I don’t know how much we were emphasizing before the COVID pandemic, but after, the last three or four years have been tough. Healthcare providers, caregivers, patients themselves, mental health checkup, that can also be contributing to fatigue, not getting out of bed, in addition to the organic medical problems. So, let me advocate a multifactorial approach, scientifically summed up as treating what you can with the underlying MPN, fine, treating the side effects and symptoms of the MPN, as you said. 

And then, other, which can be a huge bucket, particularly as we get older, to not forget about that. Again, checking the thyroid level. And then when you’re on these different treatments, you can personalize it. Interferon, obviously, has its own separate set of side effects and then of course the other agents. So, I think that may be the best way to approach it. Maybe a three-bucket approach. The MPN itself, and then the treatment itself, and then the other, something like that.  

Katherine Banwell:

Yeah, yeah. And as you’ve mentioned, it’s all going to be personalized and individualized, because what’s going to work for one person is not necessarily going to work for another.  

Dr. Pemmaraju:

Hear, hear, well said to that. You know, you think you make a great diagnosis in the clinic, someone’s having fatigue, they’re on therapy for your MPN. You check the TSH, it’s wildly abnormal. Okay, you refer them to endocrine. Six months later, the thyroid level is completely normal now on thyroid medicine. And yet, the fatigue, brain fog, everything is still not clear.  

The MPN is under good control. What gives? That’s the difficult part of these diseases. So, I really love what you said about the personalization and to keep looking and keep trying.   

Katherine Banwell:

What might an increase in symptoms mean? Does it mean that the disease is progressing or that maybe it’s time to change therapies?   

Dr. Pemmaraju:

Yeah, possibly. So, with all this objective evidence, there’s different buckets of disease progression. And some of them are objective and obvious, rising spleen, increasing blasts, or leukemia cells in the peripheral blood. The start of transfusion dependency for either anemia or platelets that weren’t there before. Sometimes, there are obvious things that you can point to, but there are a couple of scenarios where it’s not as obvious. You just named one. One is increasing symptom burden profile. You see, sometimes you have to think about, is it the sequela of the treatment itself or is it disease progression?  

I’ll give an example. If you start on an Interferon product and the dose is too high, you may be feeling not so great from the Interferon. But maybe in that case, a simple dose reduction was the answer because then you’re still getting the anti-disease activity, less side effects and all that. So, I’ll answer your question by saying possibly, but it can’t be the whole story. So, increasing symptoms is a harbinger, it’s a red flag. In the clinic, it means pause. Workup, is this a subject of the treatment itself? Is it because the disease is progressing? Do we need to do a restaging and workup, whether that means a bone marrow biopsy, whatever that means?

Or again, let’s put that other in there. What about the other comorbidities? Do you have class one heart failure, that’s now class three and you’re retaining fluid? And that’s why you’re short of breath and you actually need an echo and a cardiologist and an evaluation of your diuresis. So, I think that’s important, but the key is don’t blow it off, right? So, increasing symptom in MPN is telling you something isn’t right, and we need to check it out.  

Katherine Banwell:

Right, and for the patient, tell your healthcare team about it.  

Dr. Pemmaraju:

Communicate always. I think what we see is people are so proper and so compassionate and so kind and collegial, and that’s beautiful. But actually in the MPNs and all these rare blood cancers where so little is known and so little is obvious, communication is the key.  

Katherine Banwell:

Yeah. I’d like to make some time now to answer questions from the audience.  

Dr. Pemmaraju:

Great. 

Katherine Banwell:

And here are a few we received prior to the program. Stephanie writes, I have ET and I’m not being treated. Do you have advice for the watch and wait period? I’m anxious about the disease changing and don’t know what I’m waiting for. So, before you answer the question, Dr. Pemmaraju, would you define this term, watch and wait?  

Dr. Pemmaraju:

I will. And to Stephanie and everyone out there, this is a great question. I will say half the folks I talk to actually call it watch and worry, okay. Some people call it watch and wait, and as Stephanie’s saying, some people call it watch and worry.   

Yeah, the concept is threefold. One is that there are many cancers, many cancers, including blood cancers, that can be caught so early on that they don’t require treatment. A lot of patients with CLL, chronic lymphocytic leukemia, ET, as Stephanie mentioned, in the solid tumor. It’s very common to be diagnosed with a prostate cancer that’s low grade, early stage that can be observed. Number two is in ET, there is a science behind it.   

What we found in our studies, and they can be updated over time and you’ll see those, the traditional is that if you’re below the age of 60 and/or you’ve had no blood clot, thrombotic event, that’s considered low risk. And the treatment can be observation, perhaps adding in a baby aspirin to prevent against blood clots if there’s no contraindication. Now what’s magic about that age 60, obviously as you know, it’s not magic. It’s more of a statistical, continuous variable algorithm that says around that time, the risk of blood clots goes up. And so then you’d consider cytoreductive therapy at that point. Now there’s exceptions to that.

Many of our young patients are on therapy, but there’s usually some reason for that. Some high-risk feature, wildly uncontrolled blood counts, for example, symptom burden, some other high-risk features. So, it’s a suggestion. It’s a guideline, not an absolute. And then the third part of it is, the what do you do in that time? And that’s the frustrating thing. And I think that’s what Stephanie’s getting to.  

Again, that’s why I said the watch and worry versus watch and wait. Some of it is, how are you feeling outside of this? Some patients take it as a great news. Hey, you have this blood cancer, that’s not good news. But the good news is it’s probably not going to be active for a long time, we can, “just watch it.” But some people, as Stephanie is saying, take it the opposite way. What do you mean I got a blood cancer? I got something lurking in my body. You’re telling me it’s there, you know it’s there. And so what’s up with that? And the concept there is that some of these situations like low-risk ET, we found that if you treat too early, too aggressively, you can actually do harm.  

Katherine Banwell:

Oh. 

Dr. Pemmaraju:

So, that’s the key. These chemo drugs are not benign as you had me discuss earlier. They have toxicity, side effects, short-term, long-term. So, it’s a risk-benefit thing. If the risk far outweighs the benefit, as in the younger patient with no symptoms, no high-risk features, observation is okay. But at some point, when it turns, that’s the threshold.  

So, really the key is, if we believe these are stem cell blood cancer disorders, we need to be thinking about and designing therapies with minimal to no toxicity. Something that actually modifies the disease early on and something that leads to long-term outcomes. And we don’t have that yet in ET. We’re working on that in PV and myelofibrosis. So, stay tuned for that. And then finally, let me also add, this is an important point, not everybody gets it. This watch and wait versus watch and worry. So, I’m glad Stephanie brought that up because it’s not always good news, uniformly, when you tell someone, good news is you don’t have to do anything bad news, there’s something there.  

Katherine Banwell:

Right. Jess wrote in with this question. I’ve been experiencing bone pain and neuropathy. Is there anything that can eliminate or reduce these symptoms?  

Dr. Pemmaraju:

Great question, and it ties into our earlier question about the MPN symptom burden. On the original MPN-10 scale that Ruben and others pioneered, you will see both of those. You will see the bone pain, neuropathy.  

Now there’s been, you know, different narrowing down of these questionnaires and things, but in general, our patients do have these and that’s across the board. So, not only myelofibrosis but also our patients with PV and ET. These are among the most frustrating, I would say. Again, as you would expect, if you are advanced enough and you’re getting treatment, you hope that the treatment itself, whether it’s the Interferon or the JAK inhibitors or whatever you’re doing, clinical trial, hopes to alleviate those. But it doesn’t all the time.

Then the second issue is, these are likely the result of a cytokine storm or increased cytokines, these protein messengers that are abnormally high in our patients with MPNs. There’s varying unsatisfying things that people do. Sometimes we give antihistamines for people with bone pain. So that’s these over-the-counter sinus allergy medicines. Interestingly, the Claritins and the Zyrtecs, these type of medications, that can sometimes help in MPN bone pain. And then also for the neuropathy, these common neuropathy drugs that everybody knows, the gabapentins and all of these drugs are used frequently.  

There’s no doubt in my clinic and everybody else’s, but the varying levels of success. So, I think it speaks to the fact that these two are kind of from the MPN itself. And treating the underlying MPN is still usually your best strategy, using these, borrowing these medications, from the other aspects.

And then finally, my other plug here, which has kind of been a theme here, hopefully it resonates, and it doesn’t sound generic or unnecessary, is these things can sometimes be something else. Okay, bone pain and neuropathy can be something else. So, we do have cases of people having frequent falls, really serious stuff. In those cases, I refer those patients to a neurologist. Nerve conduction studies right, very advanced studies in the couple of cases that are so severe that it’s beyond thinking that it’s just due to the MPN.   

Katherine Banwell:

Dr. Pemmaraju, as a researcher, what are new and emerging therapies on the horizon in MPN care?  

Dr. Pemmaraju:

Well, Katherine, I’m glad you asked because I’m proud to tell you here, at the end of 2023, that we’ve now entered a new golden era of therapies for MPNs. Your group, and others, have led the way in advocating, but for so many years, honestly, we didn’t have many breakthroughs or new medicines. And now we literally have something we’re hearing about once a month. I think this golden era is divided into four buckets, Katherine, and that’s why I’m so excited for our patients and their caregivers.

Number one is novel JAK inhibitors. So, beyond the approved ruxolitinib, fedratinib, and now pacritinib, we have a fourth one that’s under consideration, that’s called momelotinib. Hopefully, we’ll have that approved by the end of the year. And there are actually other drugs around the world. So, not just in the U.S. and North America that are being developed as a further JAK inhibitor. So, just like we’ve seen in CML with the TKIs for BCR-ABL after the imatinib Gleevec medicine, hopefully, we have seven to 10 choices for our patients.  

Number two is the combinatorial approach of a JAK inhibitor plus something else. And that’s a field that I’m personally very involved in and helping to lead. The concept there is you take the known workhorse drug, the JAK inhibitor, use it as the backbone, and then add in the second agent. We started to do those studies in patients who were already starting to lose a response and we added in the second agent, those were called suboptimal studies.

And then now we’re moving those drugs into the frontline setting in international global randomized studies. So, stay tuned, let’s see how those go. But the concept is, can you take a new agent, whether it’s a BET inhibitor, a bromodomain inhibitor, a Bcl-xL inhibitor, PI3 Kinase, et cetera, and combine it with the JAK inhibitor? The third bucket that’s even more exciting to many people is that of novel agents standing alone by themselves. Now you’ve had either a JAK inhibitor or some other therapy for your myelofibrosis. That didn’t work for whatever reason. Now you’re looking for a completely new strategy.  

An explosion of research, not just in the lab, which we’ve had for the last 10 years, but over the last three or four years, amazingly, even despite the COVID pandemic. I would say dozens, really dozens of trials that are what you would consider beyond or non-JAK inhibitor therapy. Some of them include telomerase inhibition, with the imetelstat agent, for example. And so the concept here is, can you now hit the myelofibrosis in a completely different pathway?

And the answer clearly is yes. And those results have been tested now in the lower stages, the earlier stages, phase one and two. And you’re starting to see those drugs enter into the phase two and phase three. We eagerly await those results if there can be a viable beyond JAK inhibitor. And then finally, if that wasn’t exciting enough, there’s a fourth bucket, which is thinking about specifically the anemia myelofibrosis. We’ve never really historically done that. We’ve had older drugs, danazol, steroids, growth factor shots, blood transfusions.  

But now here you see both pharmaceutical interest, as well as academic interest, in developing agents that either specifically target the anemia of MF or both, the MF and the anemia. And that could be a game changer for our patients in the next five years. So, Katherine, a wealth of exploding research that I’m personally very excited about that gives me and our field hope, momentum, and enthusiasm going into 2024.   

Katherine Banwell:

Yeah. Well, Dr. Pemmaraju, as we close out our conversation, I wanted to end with a question that we usually start within our Thrive Series. In your experience, what does it mean to thrive with an MPN?  

Dr. Pemmaraju:

Well, I really love that phrase so much because it’s meaningful to me.  

You know, you’re talking about something that resonates with me and my patients, which is not just living with the MPN, but you’re talking about thriving with an MPN. That’s so resonant to us. I think really, I would go for three parts to that.  

One is that it’s an acknowledgment or a complete understanding of the disease. So, not denial, the opposite of denial, whatever that is, Katherine. So, understanding as much as you can about the disease which is, I encourage people to Google, look up on the internet. I just, what I want you to do is couple that with talking about it in context with your provider. I think the worry that people have is you’re at your home midnight, you’re Googling stuff, it may or may not be right.

So, anyway, so just do that, but then bring the information to the next visit. So, fully understanding and learning as much as you can in your own way. Number two is to be able to have a quality of life that is not just living with the disease, but actually being successful at your relationships, your work, whatever it is that brings you meaning and joy in life. And that sometimes has to do with the MPN paradigm, sometimes has to do with the other stuff we said.  

But I think, doing that, not despite the fact that you have the MPN, but acknowledging it with that, right? And then I think the third aspect is, if you have some way or some platform to be able to express yourself with the MPN because it’s such a rare disease, we think maybe only four out of 100,000 people worldwide get these. A lot of patients, not for everybody, by the way, but a lot of patients are thriving on support groups. 

It used to be you have to be in person, that’s very difficult to do with rare diseases. But now online, social media, a lot of different ways to get involved. Whether someone’s an introvert or an extrovert, whether someone wants to be private or public, all those things are hugely important, so it’s a personal decision. But for many, they want to get out there, and it’s not necessarily this scientific information exchange, although that’s good. But the support and encouragement and comradery of talking to other patients about what we’re talking about.  

It is, in fact, a little bit more facile to do it with the more common diseases, breast cancer, all of these things. And it’s much more difficult, social media online has opened that up. So, to me, I think that’s a kind of mix that I’ve been seeing in my patients. And that leads to empowerment. It leads to taking control of the things that can be controlled, leaving the things that can’t be controlled to what needs to happen. And then an understanding and anticipation of things that may happen in the next few visits, in the next few years. I think that’s how people can thrive with these MPNs. 

Katherine Banwell:

Yeah. And that’s a hopeful message to leave our audience with Dr. Pemmaraju. Thank you so much for joining us today.  

Dr. Pemmaraju:

Well, thank you, Katherine, and hats off to you and the team for not only keeping the advocacy and information going but during this pandemic time, becoming an essential source of information for our patients and getting the word out there. So, thank you.  

Katherine Banwell:

How Is Telemedicine Influencing Personalized Medicine for MPN Patients

Transcript:

Lisa Hatfield: 

So I have multiple myeloma, and, of course, that comes with side effects from the different therapies and symptoms of their own. We have a great integrative health center at our cancer center here locally where I live, and I’ve used it for acupuncture for some of my symptom management. I’ve also watched you on different platforms, through webinars and patient support groups where you describe different integrative health techniques and that type of thing. So I’m wondering…two questions. The first part is, what symptoms do MPN patients face the most? And then how can they use integrative health to do that, particularly as it relates to telemedicine? Are there telemedicine options for integrative health? I suppose things like acupuncture, maybe not, but other types of, of integrative health, and can they get a consult for integrative health? Can they even go as far as getting a consult? So if you can answer those questions, the symptoms they face, how to use integrative health, and if they can get a consult for integrative health, that would be great. We’d appreciate that.

Dr. Krisstina Gowin: 

Yeah. Well, Lisa, I want to take a moment just to validate your journey that you’re going through and to congratulate you for your self-advocacy to go look for those integrative therapies to support yourself. And for MPN patients, I will say that it’s a really unique group, and so all cancer patients experience symptoms. But in myeloproliferative neoplasms, it’s really kind of this heterogeneous what we call a symptom burden. And so most patients will experience fatigue about 80 percent of MPN patients. But then beyond that, there’s really a whole slew of different sequelae that can be associated with the disease, which you may or may not think about when you’re thinking about MPNs, such as psychosocial issues, sleep issues, sexual issues.

And then we have kind of the classical issues that happen with MPNs, such as dizziness, but we talked about the fatigue, bone pain, itching, abdominal discomfort from an enlarged spleen and early satiety, or feeling full quickly. It’s really a huge symptom complex, if you will. And we now have validated measurement tools to better understand those. It’s the MPN symptom assessment form, which has really, I think, revolutionized how we look at MPN. It’s no longer just treating the blood counts. We’re treating the patient as a whole, and even within our NCCN guidelines, kind of how we as oncologists go through the algorithms of how to change therapy and how we look at patients. We now have symptoms in there. So even if blood counts are controlled, we may change therapies or even do a bone marrow based on symptoms alone. So symptoms are a huge thing in MPN. So getting to your second question for integrative health.

So I think that MPN…the patients in the community are really early adopters for digital engagement, which is fantastic. Everyone’s very engaged, and I’ve had the opportunity to work on meditation apps, yoga apps, a wellness-based app here from the University of Arizona, and patients just really accrue fast. Everyone’s so excited. And most of these, though, were very small kind of pilot trials, looking at feasibility, can’t we really do these things? But most of them as well are showing some impacts on depression, anxiety, sleep, and total symptom burden. So I do think that these modalities through digital platforms certainly can make a difference on the symptoms. And we’ve seen that with meditation. We’ve seen it with yoga, and we’ve seen it with a seven domain wellness app. And is it the digital engagement? I don’t think so.

I think it’s likely the integrative therapies that they’re receiving through that platform, right? We know meditation works, we know yoga works, perhaps not so well in MPNs. We need to build that evidence base, but other solid cancers, we know those interventions really work. But it’s wonderful to get that kind of early data, say it not only works, but it also works when you’re doing it at home, when you’re doing it on a digital platform. And so I would encourage all patients listening to this to, yes, look at what’s around you, what are the resources, what are the clinical trials? Looking at these different digital modalities for integrative medicine, but also to go get an integrative consultation.

And as Dr. Lopez already had mentioned, she does all of her integrative medicine via telemedicine now, which is fantastic. And so you, it’s really, it’s that, you know, your fingertips. You now have access to wonderful oncologists like Dr. Lopez to guide you in this journey. And the journey is not only allopathic Western medicine, but it’s treating you as a person, you as a whole symptom complex. And that’s really what integrative medicine aims to support you through. 

Lisa Hatfield: 

And you mentioned that Dr. Lopez also does her integrative health via telemedicine. So I’m going to ask, Dr. Lopez, can you speak to that a little bit more? How do you do that with patients? Do they just contact you and set up an appointment for an integrative health consult or appointment? And do you conduct some of that yourself, or do you send them to particular resources in the community?

Dr. AnaMaria Lopez: 

Sure. So, yes, patients can make an integrative oncology appointment directly. I really like to do the consults through tele simply because I can…as I was mentioning, it’s like a virtual house call to really get a sense of the patient. Often a partner, significant other, caregiver might be present as well, and as we know there’s the survivor and there’s the co-survivor. So including both can be very helpful to some people, and I think the initial intake…again, as Dr. Gowin was saying, it depends so much on what the person wants to do. So the first opportunity for coming together is simply, “Where are you? What are your goals? What’s important to you? And of the panoply of options, which might be the easiest or the one that you are most interested in?”

And so depending on what it is, we might work together, we might also bring in others if the person is really interested in making lifestyle changes, let’s say related to nutrition. The person might work closely with a nutritionist for some period of time and then come back, and we’d come together and reassess. You mentioned the acupuncture, and you can’t do acupuncture at a distance, but you can certainly teach people about the points and consider acupressure for certain points. So there are so many ways to engage and interact, but yes, I think like a lot of medicine, it’s a team-based approach.

Katherine Banwell:

Hello and welcome. I’m Katherine Banwell, your host for today’s program. Today’s webinar is a continuation of our Thrive series. And we’re going to discuss how to manage life with an MPN.  Before we get into the discussion, please remember that this program is not a substitute for seeking medical advice. Please refer to your healthcare team about what might be best for you.  

Let’s meet our guest today. Joining me is Dr. Raajit Rampal. Dr. Rampal, welcome. Would you please introduce yourself.    

Dr. Raajit Rampal:

Hi. Thank you so much for having me. I’m Raajit Rampal from Memorial Sloan Kettering Cancer Center where I focus on myeloproliferative neoplasms. 

Katherine Banwell:

Thank you so much for being with us today. 

Dr. Raajit Rampal:

My pleasure.  

Katherine Banwell:

As we do with each of the webinars in our Thrive series, let’s start with this question. In your experience, what do you think it means to thrive with an MPN? 

Dr. Raajit Rampal:

It’s a great question, right. I think taking a step back, when we think about our patients with MPNs, one of the questions I always have for patients are what are your goals. And inevitably and invariably, people want two things. They want to live longer and they want to live better. And so, I think that thinking about thriving with an MPN to me is about how do we minimize the impact of an MPN in someone’s life. And that means a couple of things. One that means how do we deal with symptoms or things that are causing medical problems. 

But two, how do we deal with the anxiety of a diagnosis? In many cases in my experience, that can be just as detrimental to somebody’s well-being as the actual physical symptoms of the disease.  

Katherine Banwell:

When it comes to choosing therapy for polycythemia vera essential thrombocythemia, or myelofibrosis, it’s important to work with your healthcare team to identify what is going to work best for you. So, to begin, would you define shared decision making and why is this critical to properly managing life with an MPN? 

Dr. Raajit Rampal:

Yeah. Shared decision-making, to me, is really about the physician or whoever is on the healthcare team providing the patient all of the information needed to make a good decision. That means what are we trying to do? What is the medication or invention going to accomplish? What are the side effects because there are always side effects.  

And what do we think that’s going to do or how is that going to impact the patient’s life? Where things get nuanced is that patients come to us because we have expertise. There are two extremes. One extreme is that the physician says this is the medication you should take. End of discussion. The other extreme though is also not helpful, which is to say to a patient here are five choices. Here are the side effects. You pick one. Our job is to lay out those side effects and the benefits but then, also help guide a decision. 

Katherine Banwell:

What are treatment goals and how are they determined?  

Dr. Raajit Rampal:

It depends on the disease to a large extent. Now, when we’re dealing with ET and PV, the primary goal of our interventions is to reduce the risk of a clotting event or bleeding event. And that usually involves controlling the blood counts in some cases, not in all patients with ET. 

Sometimes aspirin is all we do. Myelofibrosis is a little bit more complicated because it depends on what the problem is. Not all myelofibrosis patients have the same challenges. Some have anemia that needs treatment. Some have a big spleen. Some have symptoms and some have nothing and they just need observation. So, it’s a bigger list with MF patients. But I think the first part of the discussion always is defining what the goal needs to be. 

Katherine Banwell:

What factors are considered when choosing therapy for ET, PV, and MF? 

Dr. Raajit Rampal:

I think a couple of things. One is what medication we think is going to benefit the patient best. That has to take into account the individual, their willingness to take certain medications, for example, pills versus interferon injection. Some people have an aversion to self-injection, which we have to take that into account. What are the other medical conditions that the patient is dealing with? 

And the reality is, in some cases, it’s cost because these medications, depending on a patient’s insurance, can have quite a different spread in terms of cost. Unfortunately, that is something we have to take into account. 

Katherine Banwell:

Let’s talk about what sort of tests should be done following an MPN diagnosis. Can you tell me about those? 

Dr. Raajit Rampal:

Yeah. Fundamental to the MPN itself, the things that we really want to know is, in most cases, a bone marrow examination is needed because that will tell us really what the disease is that we’re dealing with. It will tell us about the genetics. I strongly believe we have to be comprehensive in our genetic assessments because that does prognosticate and sometimes gives us an opportunity in terms of treatment. Chromosomal analysis. These are the basic bread and butter hematology tests we want to do from the bone marrow to really understand what the patient’s disease is. 

Beyond that, I think that particularly in patients with PV and ET, it’s important that we partner with their primary care physicians to make sure that they’ve had, for example, testing for diabetes, a recent lipid profile, any cardiovascular tests, particularly measurements of blood pressure because these things are all important in terms of an ET or PV patient’s risk of having a blood clot. So, there are, again, things that are within hematology realm but then, there are other general health things that become really important in somebody who is diagnosed with PV or ET. 

Katherine Banwell:

How often should lab tests of blood work be done? 

Dr. Raajit Rampal:

It really depends on the patient. For some patients with PV, for example, they need to have their blood checked every three weeks because they’re having frequent phlebotomies. Whereas some patients with ET could probably go forward to six months between blood tests.  

So, it depends on the individual. 

Katherine Banwell:

How can results of biomarker testing affect treatment choices for patients with MPNs? 

Dr. Raajit Rampal:

 question. The genetics are becoming increasingly important in our treatment decisions. So, let’s take a simple example, which is patients with ET. Calreticulin and JAK2 and MPL are the three most common mutations that we see. But they have very different invocation. So, somebody could have a calreticulin-mutated ET and based on them having that calreticulin mutation and no other factors like no history of clotting, that patient may never need to go on a medication aside from aspirin. And even early on, it’s debatable whether or not some of these patients really need aspirin at all. 

Whereas somebody who had a JAK-2 mutant ET, our guidelines and data suggests that that person, once they reach a certain age, should probably be on medication. So, that’s kind of perhaps one of our more clearcut examples of a genetic biomarker telling us how to approach treatment. 

And then, it gets more nuanced from that and more exciting and interesting in the sense that there are mutations, for example, that occur in myelofibrosis and in patients whose disease is progressing towards leukemia, such as IDH mutations. And these are things that are now targetable with FDA-approved drugs.  

And there are now clinical trials combining JAK inhibitors and IDH inhibitors for patients who have more advanced disease who have these IDH mutations. So, you go from on one end, these genomic markers being of prognostic significance and now, on the other hand, we’re getting to a point where, in some cases, they might tell us how to best treat a patient. 

Katherine Banwell:

Dr. Rampal, should all patients diagnosed with MPN’s undergo molecular testing? 

Dr. Raajit Rampal:

I strongly believe that. I think that we’ve learned so much that these tests have prognostic value. 

And in some cases, it may suggest a slightly different diagnosis. I definitely think that should be the case. 

Katherine Banwell:

What should patients be asking once they have the results? 

Dr. Raajit Rampal:

What does it mean? That’s the most basic and fundamental question. It’s one thing to get a list of mutations. But the real bread and butter question is what does this mean to the disease and my prognosis and my treatment?  Those are the key questions.  

Katherine Banwell:

So, what are the types of treatments available for MPNs?  And let’s start with myelofibrosis or MF. 

Dr. Raajit Rampal:

If we had had this discussion five years ago, it would be pretty simple, and it would take a minute or two. And that’s completely changing and that’s amazing, and it’s good for all of our patients.  

Right now, for patients with MF, it depends on what the issue is. If the issue is symptoms or spleen, JAK inhibitors are our first line of therapy. Three approved JAK inhibitors are currently available, two on the first side ruxolitinib (Jakafi) and fedratinib (Inrebic). And pacritinib (Vonjo) can be used for patients with really low platelet counts.   

There is a fourth JAK inhibitor that we expect to be, hopefully, approved in June of this year, momelotinib. So, the landscape is about to complete broaden in terms of just JAK inhibitors.  

But beyond the JAK inhibitors themselves, there are a number of late stage clinical trials that are combining JAK inhibitors with agents that work through a different mechanism that don’t work through inhibition of the JAK pathway. So far, these drugs have all shown promise in early phase trials. Now, the definitive Phase III trials are being done. We have to wait and see what the data tells us. But if these are positive trials, this could completely alter the landscape of MPN. 

Katherine Banwell:

There’s also transplants available, right? 

Dr. Raajit Rampal:

Correct. Transplants for more advanced patients, which comes with some major risks. And so, that has to be thought of very carefully in terms of the risks and benefit. But it is a potentially curative strategy.  

Katherine Banwell:

Let’s turn to polycythemia vera or PV. What types of treatments are available? 

Dr. Raajit Rampal:

It’s really quite a range. So, there are things like phlebotomy and aspirin, which has been the mainstay of therapy for many years. There are drugs like hydroxyurea (Hydrea), interferons, JAK inhibitors. So, ruxolitinib is approved in certain settings for treating polycythemia vera. So, the landscape is broad. There are a lot of questions going on right now with polycythemia vera with regards to how it should best be treated. Is the mainstay of phlebotomy and aspirin really what we should be doing or should we be giving patients treatment earlier on. 

And there is some data to suggest that. There is this drug called ropeginterferon (Besremi) that’s FDA-approved for polycythemia, which was compared in the study to phlebotomy and aspirin.  

And at least the data suggests that there may be better control of the disease and less progression possibly, and it’s a small number of patients, by treating patients earlier. Whereas we would have just given phlebotomy and aspirin. So, it’s something to consider. There are drugs in clinical trials as well that look promising one of which is called rusfertide, which actually works by changing the way iron is used by the body. 

Iron is a key component to hemoglobin and it is, of course, a key component to polycythemia in the sense that we phlebotomize patients to make them iron deficient and that’s how we control the disease. But this is a pharmacological way to do that. So, that drug is now in Phase III trials. So, that may also alter the landscape of treatment of PV in the near future. 

Katherine Banwell:

Finally, how is essential thrombocythemia treated? 

Dr. Raajit Rampal:

So, in some cases, with absolutely nothing as we had talked about a moment ago. There is some thought that in really, really low-risk patients. Maybe you don’t need to do anything except observe them. Whereas most patients are on an aspirin. And beyond that, we have drugs like interferon, pegylated interferon, and hydroxyurea and anagrelide, all of which can be utilized. It’s not entirely clear if there is one distinct first line treatment that is the best but these drugs are all active. JAK inhibitors have been studied in this setting. And to date, the data hasn’t led to their approval but, certainly, people have studied it.  

Katherine Banwell:

Dr. Rampal, how can you tell if a treatment is effective? Are there signs that you look for? 

Dr. Raajit Rampal:

Well, I think it’s a couple of things.  

One, are we meeting the treatment goals in terms of are we controlling blood counts with ET or PV? That’s one of the first principles in management. And with regards to MF, the same thing. Are patients’ symptoms being controlled? Is the spleen being adequately controlled? And then, there’s the symptom burden because just because the blood counts are being controlled, patients may still have symptoms, in which case, they are not being adequately treated. And then, we have to do our best to try to find a treatment strategy that does control their blood counts but also does control their symptoms. 

So, there is the blood count perspective but there is the symptom perspective as well. 

Katherine Banwell:

How do you know when it’s time to change treatments? 

Dr. Raajit Rampal:

Well, I think really two things. One is if we aren’t meeting our goals like we just talked about. But the other aspect of that is if we are incurring toxicities that are just not tolerable to the patient and that’s a reason to change therapy always. 

Katherine Banwell:

Many patients, of course, worry about disease progression. Are there key predictors or tests for progression that patients should know about? 

Dr. Raajit Rampal:

This is a key area of investigation currently. I think one of the things that patients say to us so often when we meet them is what’s going to happen to me. And right now, we don’t have great prediction tools. We can say on a population level well, there is X percent of chance of progression at 15 years. That’s useful if you’re talking about a population. That’s not really useful if you’re talking to an individual. Because if I say to somebody there’s a 20 percent chance of your disease progressing to leukemia, it doesn’t really make a difference. That’s a meaningless statement because if you’re in the 20 percent who progress, it’s not a relevant statistic anymore.  

It’s sort of a binary thing. We’ve got to do better at developing this. This is something that the MPN Research Foundation is really heavily invested in in trying to identify predictive biomarkers. 

If we can do that, then perhaps what we can do is say to a patient this is really what we think your actual risk is. And then, the next step is asking the question if we intervene early, can we prevent that progression from occurring. So, that’s where I think we need to go. We aren’t there yet. 

Katherine Banwell:

What signs or symptoms do you look for that may indicate that the disease is progressing? 

Dr. Raajit Rampal:

The blood counts are often the canary in the coal mine regardless of the disease. They can tell us if ET or PV is progressing into MF or whether MF is progressing to more of a leukemic phase. Changes in symptoms sometimes can be a harbinger of disease progression. So, Patient 2, for example, is doing really well and now, he’s having drenching sweats and losing weight. So, those types of symptoms are a sign that physical findings is the size of the spleen if it’s increasing. 

All of those things together give us a hint about progression.  

Katherine Banwell:

Well, is there any way to prevent progression?  

Dr. Raajit Rampal:

That is the million dollar question. Again, that’s where we ultimately need to be. We want to be able to intervene to a point where patients don’t get that sick. It would be amazing if we’d come to the point where we can intervene early and nobody progresses to late stage MF. Nobody gets leukemia. And I think that’s a worthy goal. That’s not something that we should think is too lofty of a goal. That should be our ultimate goal here. And a number of groups are investigating this exact question. It’s complicated and it’s going to take time. But I think that’s a worthwhile investment. 

Katherine Banwell:

Let’s talk about MPN symptoms and treatment side effects. Here’s a question we received from a viewer before the program. How common is peripheral neuropathy in primary myelofibrosis? 

And what is the best treatment for it? 

Dr. Raajit Rampal:

Well, by itself, it’s not a very common symptom of MF by itself. Can it be a symptom? Sure. But there are also a number of things that can cause peripheral neuropathy. So, I’m not sure there’s a best treatment.   

But what needs to be done is a thorough investigation. There can be a number of causes. It could be nerve injury. It could be a deficiency in vitamins like B12. There are a lot of things that could cause it. So, that type of a symptom needs to be thought of in a broad way in terms of diagnosis.  

Katherine Banwell:

Jeff sent in this question. How could I manage the itching? Are there new treatments or strategies to live with itching? 

Dr. Raajit Rampal:

Very common thing. And it’s an interesting thing explaining to when we teach our trainees about this symptom, we have to impress on them the fact that itching is not the itching that everybody else experiences. 

This is a very profoundly different symptom. It’s debilitating for so many people. I have patients who go to the Emergency Room for that. That’s how terrible it could be. There are a lot of things that could be tried. JAK inhibitors, in my experience, work very well for itching but not in everybody. We use sometimes antihistamines that can work well. Sometimes, antidepressants can work well, not because they’re treating depression but because of other properties that they have. And sometimes, UV light therapy can be useful tool here, too. A lot of patients swear by it. 

 Katherine Banwell:

Another common side effect is fatigue. Do you have any advice for managing this symptom? 

Dr. Raajit Rampal:

Fatigue is the most common symptom across MPNs. And it is also one of the most difficult things to treat. Part of the issue is trying to figure out what does fatigue mean to the patient.  

When someone says they’re tired, does that mean they’re sleeping all of the time? Does that mean they don’t have get up and go? The first step is always understanding what does fatigue mean to the patient? And then, the second is trying to dissect that. In some cases, it’s related to anemia, in some cases, it’s not related to anemia and it’s just the disease itself.  

And in some cases, you have to think outside of the box about general medical issues like thyroid dysfunction that could be at play here. So, there isn’t one best fit. 

But the first test is always to dig deep. When someone says they have fatigue to dig deeper and try to figure out what is that really. 

Katherine Banwell: 

What other common symptoms do you hear about from patients? And what can be done about those?  

Dr. Raajit Rampal:

There are a lot of different things. It’s a spectrum. So, I think that itching and fatigue are very common. Feeling full early is, that’s a big thing, particularly in myelofibrosis patients.  

Bone pain, that’s another big one, particularly in myelofibrosis. There is not one therapy that is best for all. I think the JAK inhibitors, certainly, benefit many of these symptoms. But they don’t benefit everybody and not to the extent that makes it tolerable for everybody. So, often times, we struggle with this and try a lot of different things. But, again, I think one of the things to always remember is we don’t always want to say that this must be because of the MPN. Sometimes, symptom is arising because of another medical condition that’s going on concurrently. 

Katherine Banwell:

That’s good advice. Thank you. Let’s answer a few more audience questions we received. This one is from Calvin, “If your hematologist says you’re stable and responding well to Hydrea, should you still seek out a second opinion?” 

Dr. Raajit Rampal:

It’s never wrong to seek out a second opinion. I strongly believe that, especially when you’re dealing with a disease that’s rare like this. 

And even seeking out a second opinion, even if you’re under the care of an expert in the field is never a wrong thing. I think that no one person knows everything. And sometimes, people’s experience and perspective is different. So, I don’t think that’s a bad thing ever.  

Katherine Banwell:

As a follow-up to Calvin’s question, is it sufficient to just look at what the blood tests reveal? Or does having  bone marrow biopsy dictate what treatment you should follow? 

Dr. Raajit Rampal:

I think the bone marrow is important, particularly at initial diagnosis or when there is a change. The blood counts are the canary in the coal mine. So, they tell us is there something else going on that we’re not thinking about. And that’s when the bone marrow becomes important. So, I definitely think bone marrow is important at certain points in the disease.  

Katherine Banwell:

Sandra has this question, “Are there new treatments for polycythemia vera being researched beyond interferon?” 

Dr. Raajit Rampal:

Yeah. So, we talked about rusfertide as an example of this. And there are, certainly, other drugs that have been evaluated in this space. So, there is a lot of work going on for this disease, which is really encouraging. 

Katherine Banwell:

Carolyn sent in this question, “Is there a possibility of bone marrow fibrosis reversal in myelofibrosis without a stem cell transplant?” 

Dr. Raajit Rampal:

The answer is yes. So, even with JAK inhibitors, we see that about a third of patients will have a reduction in bone marrow fibrosis. And this is a key question being investigated with some of the newer therapies that are being introduced into the treatment of myelofibrosis. And, certainly, we’ve seen data to date that suggests that the fibrosis can be reduced if not potentially eliminated in some cases.  

Katherine Banwell:

Dr. Rampal, should all patients diagnosed with MPNs undergo molecular testing? 

Dr. Raajit Rampal:

I strongly believe that. I think that we’ve learned so much that these tests are prognostic value. 

And in some cases, it may suggest a slightly different diagnosis. I definitely think that should be the case. 

Katherine Banwell:

What should patients be asking once they have the results? 

Dr. Raajit Rampal:

What does it mean? That’s the most basic and fundamental question. It’s one thing to get a list of mutations. But the real bread and butter question is what does this mean to the disease and my prognosis and my treatment?  Those are the key questions. 

Katherine Banwell:

Andrew wants to know does Jakafi cause other mutations to develop? 

Dr. Raajit Rampal:

That’s a really good question. Right now, we don’t think the answer is necessarily yes. We have seen that in some patients where the disease has progressed on Jakafi, mutations have emerged. 

But the problem is that genetic testing has limits of detection. In other words, the mutation appears, it may not have just appeared or been caused by the drug but that it may have been below our limits of detection and actually grew while the patient was on therapy, which does not mean that the drug caused the mutation but that it was allowed to emerge during treatment with the specific drug. So, that is an area of investigation.  

Katherine Banwell:

Well, thank you, Dr. Rampal. And please continue to send in your questions to question@powerfulpatients.org and we’ll work to get them answered on future webinars.  

You mentioned earlier clinical trials. And I’d like to dig a little bit deeper. Where do these fit into the treatment plan? 

Dr. Raajit Rampal:

I think they should always be considered. None of the therapies that we have do we consider curative. And in many cases, standard therapy is fine given a patient’s clinical situation. In a case where standard therapy is not working or where we think that a patient’s prognosis is particularly challenging, or if they have mutations that may confer resistance to current therapies. 

I think in those scenarios, a trial should always be considered. 

Katherine Banwell:

So, if a patient is interested in possibly participating in a clinical trial, what kinds of questions should they be asking their healthcare team? 

Dr. Raajit Rampal:

All of these trials are different. I think the first thing is to discuss what’s the risk, what’s the benefit of any given trial or drug. What stage and development is it? What’s the evidence to support it? And what can I expect from it?   

Katherine Banwell:

What about cost? 

Dr. Raajit Rampal:

So, trials, in general, have two components. One is what we call standard of care meaning that things we would do normally for in the course of a patient’s treatment would be billed to a patient’s insurance as if they weren’t on a trial. 

Almost all trials, the study drug or any tests that are being done specifically with regards to the study drug are all covered by whoever is sponsoring the trial.  

Katherine Banwell:

How do patients find out about where the clinical trials are taking place? 

Dr. Raajit Rampal:

Usually, their physician should either, if they’re in a specialized center, they’ll have access there. But if they’re interested in trials and they’re being seen, for example, by a physician in the community who doesn’t necessarily specialize, asking for a referral to a major center where that MPN expertise is not an unreasonable approach to that. There is also clinicaltrials.gov where patients can go look for ongoing trials for their particular diagnosis.  

Katherine Banwell:

So, if patients want to learn more about MPNs, what sort of resources would you recommend? 

Dr. Raajit Rampal:

The thing I always say to patients is the internet is a very dangerous place for a variety of reasons. We have to, I think, do a good job of communicating to patients what are the resources. And the ones that I always point patients to are, for example, the MPN Advocacy International, the MPN Research Foundation, The Leukemia & Lymphoma Society, and the American Cancer Society. Those are sources of information that are vetted by physicians. 

Some of that information is specifically for patients. Those, to me, are good sources for patients to read.  

Katherine Banwell:

Dr. Rampal, as we close out our conversation, I wanted to get your thoughts on where we stand with progress and MPN care. Are there advances in research and treatment that make you hopeful? 

Dr. Raajit Rampal:

Without a doubt. I think I’ve seen more progress in the last three years than I’ve seen in the last 10 years. And we have so many new drugs coming forward, new questions that we’re trying to answer, tough questions as you alluded to. The question about prognosis but also intervening early to prevent progression of disease. These are things that are difficult questions that we are trying to dig into now. So, I think we should be optimistic. We are seeing so many excellent developments. We’ll have to see how far they’re going to take us. I don’t think we know the answer to that. But this is an exciting time.

Lisa Hatfield:

So I think we’re going to talk just a little bit, we’re going to move on to talking about best practices for MPN patients and families using telemedicine. Dr. Palmer, we’ll just start with you and then talk to Dr. Sirintrapun about that. But what are the best practices for MPN patients utilizing telemedicine? And what are some of the newer technologies that we’ve even talked about today that are being explored that you’re most excited about?

Dr. Palmer:

Well, again, I think it’s hard to say the right way to use telemedicine. I think that, as much as automation and trying to come up with processes that are very standard is important, I think it is still a learning process. How long is it safe to do telemedicine? How many, if I’m the only provider seeing this person and there’s not somebody physically looking at them, am I doing a disadvantage? So like, what’s the safety realm in that? I mean, that is something that I know comes up and it comes up with a lot of physicians, like, “Well, I have to examine the patient, I have to eyeball the patient.” So trying to figure out that balance of making sure you’re providing good quality and safe care, but that you’re also allowing for people to have access to things they otherwise wouldn’t have access to.

And some of that is a matter of having good collaborations with providers in different places and the willingness of the local providers to work with one of us. And some of that’s just kind of saying, “Well, I’m going to try this.” And then after a while if you say, “Hey, this isn’t working well,” then you switch it. But I think a lot of this is something that you can’t prescribe. It is something that needs to be the level of comfort for the provider, the level of comfort for the local provider and the patient. And it’s not going to be the same for any two patients. There certainly is going to be some variability. I’m very excited about the ongoing telemedicine and our ability to utilize it. I’m really hoping that even after the public health emergency, some of the barriers to being able to provide telemedicine outside of your own state will not be a problem. And I think each institution’s handling it a little bit differently.

So that’s something I’m excited for and there’s probably going to be a lot more that I can’t even begin to think about that’s going to come up in terms of ways that people can, like there’s handheld imaging machines and stuff like that. Is there going to be a way that we can actually have patients apply it? So, for example, I like to feel spleens in patients who have myeloproliferative diseases because they’re often enlarged. Is there going to be a way that there’s some type of equipment or some type of material that can do a spleen exam without me actually having to physically see the patient and lay hands on them? This is something that I probably, people are thinking about who are a lot smarter than me. And I’m looking forward to something like that being developed. But that’s what I’m hopeful is that we get to the point where I can feel like I’m providing really top quality care to people who could be anywhere in the United States or even honestly the world.

CLL and Anxiety: How Your Healthcare Team Can Help

Transcript:

Katherine:

Can you please talk about common side effects of CLL – which, of course, we’ve covered already, but both the ones from the disease itself and then ones related to treatment, and what can be done about these? 

Dr. Bhat:

So, disease-related side effects, or we call them disease-related symptoms, include fatigue as a common symptom. Unintentional weight loss can happen. Fevers, chills, or drenching night sweats can happen. We call them, “B symptoms.” Spleen can enlarge, and the enlargement can cause belly pain or feeling of fullness quickly after a meal since spleen is close to our stomach, and as it enlarges, it limits the space stomach can take up in the belly. Lymph nodes can enlarge and can get uncomfortable. So, if any of these symptoms happen, then we have to treat the CLL, and once we start treating the CLL these symptoms should go away. 

As far as treatment-related side effects are concerned, for example, BTK inhibitors are associated with a certain set of side effects. For example, patients can have muscle cramping, muscle pain, joint pain. Patients can have diarrhea. Some of the side effects that we worry about is change in heart rhythm, for example, atrial fibrillation. We talked about that, or increased risk of bleeding.  

Those are some of the side effects we worry about, and if those were to develop, then, of course – for example, a patient has atrial fibrillation, and if it’s symptomatic, we hold the medication. We take care of the atrial fibrillation, usually in collaboration with cardiologists, and once that’s under control, then we have to decide what to do with the treatment. If the atrial fibrillation is under control, we can re-initiate the treatment, or we can go to one of the next-generation BTK inhibitors – the acalabrutinib (Calquence), the pirtobrutinib (LOXO-305), which have less of those side effects. 

Bleeding tends to be a concern, but anything that reduces the risk of bleeding like other medications, aspirin, clopidogrel (Plavix), other blood thinners, we can avoid them, monitor these patients very closely for any of these side effects, so that’s critical. With venetoclax, it’s usually very well-controlled. It’s the initial part of treatment that tends to be a little bit intensive because of the specific side effect called, “tumor lysis syndrome,” which means that the drug works very quickly, and cells die off quickly, they can release stuff in the blood, and things can collect in the blood. 

Uric acid can go up, electrolytes can be up, any number can go up. So, we are aware of this side effect, and we actually pre-emptively have things in place that can prevent this from happening, or if it happens, we manage it right away. For example, venetoclax has a specific dose initiation. For example, it’s called, “dose ramp-up.” We start it at a lower dose, 20 milligrams, for one week. Escalate it to 50 the next week, 100 the third week, 200 fourth week, and 400 the last week, which is the standard dose. They continue on 400 from there onward. 

And even with the slow dose escalation, in the early couple of weeks, we monitor them very closely. Once we initiate a dose, we bring them back to the clinic to recheck their blood work to see if there are any changes. If any changes have happened, we hydrate them, initiate medication for their tumor lysis syndrome. 

If the risk of tumor lysis is very high, then we monitor then admit them to the hospital. Otherwise, long-term side effects of venetoclax, what we have noticed mostly is gastritis, most side effects – mostly diarrhea. But that’s usually well-controlled. We can manage it well with supportive care.

How to Treat PV-Related Itching


Transcript:

Katherine Banwell:

I would imagine monitoring patients is different for each of the MPNs. So, how are patients typically monitored over time, and let’s start with essential thrombocythemia?  

Dr. Scandura:

Yeah. I think – again, it’s similar. You know, what’s near-term, what’s long-term? And so, in all of these diseases, thrombosis risk is a near-term risk. That’s something that I am monitoring in certain ways to help mitigate that risk. In ET and PV, I approach them similarly. Blood counts are certainly – these are diseases of the blood forming system. Certainly, monitoring blood counts I find helpful. But the reality of it is, in ET, there is not a clear linkage between blood counts and risks.  

And so, I like to keep the platelet count near normal if I can. But I also recognize that it may not be worth suppressing all of the blood counts to achieve that landmark, because it’s not clear that that’s really reducing the risk any more than just having somebody on a medication that helps control the blood counts. In polycythemia vera, different blood counts are very important. The red blood cells are kind of like part of the clotting risk. We know from clinical trials that keeping the red blood cell parameters within certain ranges reduces the risk of clotting. And so, what I monitor in polycythemia vera is the hematocrit. In women, I like to keep it below 42. In men, I like to keep it below 45.  

But I don’t just – I’m not a slave to the hematocrit. I am keeping an eye on the other blood counts and the other red blood cell parameters. So, for instance, what’s the size of the red blood cells? That tells me a little bit about what’s going on in the blood formation for that patient. And what’s the number of red blood cells? So, sometimes people can have very small red cells, because they’re a little iron-deficient and have a huge surplus of the number of red blood cells. And that tells me a little bit about how their blood forming system is responding to therapy.  

Iron deficiency in polycythemia vera is very prominent. I personally believe it’s a very major driver of symptoms in patients who are receiving phlebotomy as part of their care. And it’s something that I monitor and really counsel patients on. My goal is to make phlebotomy independent, but it can take a while.  

Everybody starts out iron-deficient, and then we take iron out of their body through blood with the phlebotomy. And that makes them more iron-deficient.  

Katherine:

Right. 

Dr. Scandura:

I monitor symptoms from patients, and sometimes that can tell me that their disease needs to be – their treatment needs to be tweaked a little bit, even something as simple as aspirin. People can sometimes have burning in the skin or itching that is sometimes responsive to changing the aspirin dose or how it’s given, once a day versus twice a day.  

And that simple thing can be a big change for a patient who’s kind of, literally, climbing out of their skin or wishing they could and to try and find something that is helping.   

I had a patient the other day. He had COVID. I said, “Oh, you should probably get this medication.” Do you have your primary care physician? Who’s taking care of you?” And he goes, “Well, to be honest with you, you’re my guy.” And so, it’s true. I see this patient a lot. And so, sometimes they forget. If I’m not paying attention to their blood pressure, the risks or treatment of diabetes, cholesterol, lipids, their screening programs for mammogram or colonoscopy, health maintenance issues, I do keep an eye on that in patients, because I do think it’s a part of the MPNs.  

I think that there are excess risks for patients for some of these factors. Certainly, if you think of it as three strikes, they get a strike for having an MPN. I don’t want them to have any other strikes. So, diabetes, hypertension, those are strikes that I can potentially, at least, treat or refer them to somebody to help comanage with me. And so, that’s kind of my general approach. 

Katherine:

What about patients who have myelofibrosis? Are they monitored more closely? 

Dr. Scandura:

Yeah, I think it depends a little bit on the patient. Patients with early myelofibrosis often don’t have any symptoms or near-term risks much different than those from ET or PV. As the disease can progress, then some of these patients have more profound problems with symptoms, which I may be trying to find a solution to make them feel better. And also, blood counts can become more of an issue.  

Transfusions in some patients who are very high white blood cell count, the spleen is often quite enlarged. Although, in my experience, most patients aren’t really bothered by the size of their spleen as the physicians are. But it is something where I think, on average, they’re monitored a little bit more closely to quite a bit more closely depending on the patient. 

Katherine:

What happens if someone suddenly has a change in blood counts? What do you do? 

Dr. Scandura:

Yeah. I mean, repeat it. That’s the first thing. Also, check what’s going on. It’s not uncommon in patients with MPNs that I’ll see them and the counts are a little bit out of whack, the white count is much higher than it’s been, and questioning them. “Oh, yeah. I had X, Y, or Z last week or the week before.” It used to be a upper respiratory tract infection, or they had a minor surgical procedure.  

And sometimes the responses to these things can be accentuated in patients with MPNs. And so, if that’s what of this story, I certainly would repeat it and let things calm down a little. And that’s often all it is. I’m much more of a monitor of the trends. So, one-time measure doesn’t generally excite me. It might make me want to have a follow-up a little more – in a shorter period of time. Of course, it depends on what the change is. But, for most of the changes that we observe, they’re relatively minor. And I will monitor them over time.  

If I see a trend where something is progressively increasing or decreasing over time, then I start thinking about what else is going on. And that’s always in the context of what’s going on with the patient. How are they feeling? What’s their physical exam like? What are the other laboratory values like?  

Katherine:

When is a bone marrow biopsy necessary? 

Dr. Scandura:

I would say a bone marrow biopsy is absolutely necessary at the time of diagnosis. I personally do not routinely monitor by bone marrow biopsy unless it’s part of a clinical trial.  

But I do perform a bone marrow or want to look at the bone marrow morphology if there is one of these changes or at least a trend that I want a little bit more information about. And so, if – or if it’s been a very long time since somebody has had a bone marrow. If it’s been five or ten years, then sometimes I may recommend we look just so we can collect a little bit more up-to-date information.  

But I don’t routinely do a bone marrow, but I will do it if there are laboratories that are kind of trending in the wrong direction, there’s symptoms, there’s physical findings that I’m just not sure about. And I think it would help me be more sure as to what’s going on and be able to discuss that with the patient. Sometimes, just to say, “Hey. Look, we were worried about this, but the bone marrow looks really good.”

Understanding Treatment Options for ET, PV, and Myelofibrosis


Transcript:

Katherine Banwell:

Okay. Katie had this question. “What are the signs of progression from PV to MF or AML, both clinically and in blood tests, and when do you need a new bone marrow biopsy to check for this happening?” 

Dr. Jeanne Palmer:

So, in terms of progression, there are several things that we see happen. 

I think most importantly is, let’s say you have PV, and you’ve always been on medication, and it’s been hard to control. And all of a sudden, you don’t need medication to control it anymore, or the same thing for essential thrombocythemia. You have been taking medication, and all of a sudden your platelets go down, and you don’t need to take drugs anymore. A lot of times people are like, “Oh, that means I’m fixed and I’m well,” not necessarily, you really need to make sure to talk to your healthcare provider and potentially get a bone marrow biopsy. 

Now, the other thing – sometimes the blood counts will actually drop too low, so you’ll have somebody who has PV, who has always been too high and then all of the sudden they come in, and their hemoglobin is very low, and they’re anemic, and that’s another situation where you do that. So, anytime the blood counts start to drop is concerning. 

Now, it’s a continuum, so the blood counts may drop as you’re at the point of transitioning but it doesn’t – it’s not like if your blood count is dropping you say, “Oh my God, I have myelofibrosis, I need a bone marrow transplant tomorrow.” That’s not necessarily the case. This is generally a transition type process. 

Also when the spleen starts to get enlarged. Now, the spleen can be enlarged even in the setting of just ET or just PV, so spleen enlargement does not necessarily mean you’re transforming, but it can be one of the things that we would see that would indicate that. 

Katherine Banwell:

Okay. 

Dr. Jeanne Palmer:

And then finally white blood cell count increasing can often be a sign of that. Now, in terms of progression to AML, that is generally something we’ll see in the blood. AML or acute myeloid leukemia, is indicated by the presence of blasts at greater than 20 percent. Now, many patients with myelofibrosis, in particular, but even PV and ET, may have blasts in their peripheral blood. Blasts are normal. If I did a marrow on every healthy person out there, they are going to have some blasts, because these are the first part of the development of white blood cells. So, they’re like baby white blood cells. But what the problem is, is when they start to grow too much. 

And so in the setting of myelofibrosis and even sometimes with these other diseases, the blasts will be in the peripheral blood primarily because the bone marrow is damaged and doesn’t hold them in very well. It becomes AML when it gets greater than 20 percent, so that blasts of greater than 20 percent in the peripheral blood or in the bone marrow but a lot of times we find it in the peripheral blood is where we indicate this has progressed to AML. 

Katherine Banwell:

Yeah.  

Dr. Jeanne Palmer:

Blasts of greater than 10 percent are also something that we really want to pay attention to, because that would suggest that the disease is starting to become more aggressive. Now, blasts vary, so for example, I’ve had patients go up to 11 and then drop back down to 3 or 4, and then they say around 3 or 4 or 5. So, you always want to make sure to double-check because one blast count at 11 percent, whereas it’s very important to address, may not necessarily reflect that you need to change in treatment at that time. Again, these blood tests, I always tell people, do not freak out over one blood test. 

Make sure you get at least a couple of them to really confirm what you are looking at.

Transcript:

Katherine Banwell:

When would you consider a stem cell transplant? 

Dr. Jeanne Palmer:

So, the stem cell transplant is based on disease risk. There is a number of ways we assess disease risk.  

The first two ones that were published a number of years back were the DIPSS score, which is Dynamic International Prognostic System Score, or the DIPSS Plus, which basically is the DIPSS and then you add to it a few other clinical features. This symptom score is based largely on things that we can see without even a bone marrow biopsy, so things like symptoms, age, number of white blood cells, whether somebody has anemia. And then the number of something called blasts, which is very immature white blood cells. The DIPSS Plus takes into account low platelets, need for transfusions, and chromosome abnormalities, which is the only test among that that needs to be from a bone marrow biopsy. 

Now, these were created prior to Jakafi being commercially available. So, we have to take a little bit of a grain of salt with those because of the fact that Jakafi probably has changed how long people can live with this disease. 

Now, more recently they’ve tried to account for these other molecular changes. So, when we take the genetic landscape of these diseases, we have the known driver mutations, so the JAK2 mutation which I have talked about, also calreticulin and MPL.  

These three mutations all affect that one pathway, the JAK/STAT pathway, so they all affect the pathway that drives the disease and they are known to be kind of mutually exclusive and definitely contribute to the formation of the disease. 

Some of these other mutations are called somatic mutations. They could be checked by things next generation sequencing or genetic analysis. There’s a number of different names that people use for this testing, but we look for mutations that are present and these mutations, number one, can sometimes tell us risk. So, there’s certain mutations that are high risk. Other times it can actually give us other opportunities for therapy, especially of the disease progresses. But these mutations are important to know for risk stratification. For example, if somebody has DIPSS score that is maybe not super high risk, but then they have one of these mutations, we know that that probably makes their disease a little bit more aggressive. 

And that’s when we think about transplant, is when we know that the disease probably has an average life – when somebody gets to the point in their disease where we estimate their life expectancy is around five years, recognizing that we’re not very good at this. That is the type of point when we start to think about transplant. But the timing of transplant is something that’s extremely difficult and a very personalized decision. It’s something that it’s really important to understand the disease risks, how we assess them and the caveats of these disease risk assessments as we move forward planning and timing of transplant and that’s something that is, again, a very, very important discussion to have at length with your physician. 

And I always recommend, there is quite a few of us out there who actually specialize in transplant for myelofibrosis and having discussions with somebody who really understands the biology of the myelofibrosis is important because it’s very different than a lot of the other diseases that are transplanted.

Expert Perspective: Hopeful MPN Research and Development


Transcript:

Katherine Banwell:

Much of the time the chosen treatment for MPNs manages the symptoms of the condition. I’d like to review the different types and classes of treatment for the three MPNs. So, let’s start with essential thrombocythemia again. When is it time to treat, and what are the options available? 

Dr. Jeanne Palmer:

Right. So, with essential thrombocythemia, that’s the disease that sometimes we don’t need to treat. 

So, we basically have a risk stratification system and this risk is based on age, history of a blood clot, the presence or absence of a JAK2 mutation. So, for example, if somebody is 28, does not have a JAK2 mutation, which is again one of those driver mutations, and never had a blood clot, they actually don’t necessarily need to do anything and just be monitored.  

Somebody who is less than 60 and has a JAK2 mutation or who is greater than 60 and does not have a JAK2 mutation, in that setting, a lot of times you can use aspirin. Now, it gets a little bit gray in terms of that over 60 without the JAK2 mutation with regards to whether at that point you really should start taking some medicine to lower the platelets. 

Now, if somebody has a JAK2 mutation, is greater than 60 or has had a blood clot, hands down they need to take medicine to lower the platelets, in addition to aspirin or whatever blood thinner they may need. So, for example, if you have a blood clot in a vein, a lot of times you need to take a blood thinner and that will be a lifelong thing. And again, we do these risk stratifications because we know there is a certain risk of clotting associated with the risk of essential thrombocythemia.  

So, for example, somebody who is less than 60 and does not have a JAK2 mutation, never had a clot, their risk of clotting is probably very close to that of the normal population. Whereas if you’re higher risk and have a JAK2 mutation and greater than 60 or have had a history of a clot, the risk of clot is probably about 4 percent per year. So, this is something that can vary quite widely, and even though that 4 percent per year on the short-term doesn’t sound like a lot, if you take it additive over years, that’s why we generally try to be aggressive about lowering the platelets.  

In lowering the platelets, the goal is to get less than 400 and doing that can be done through several different medications. The most commonly used medications is a drug called hydroxyurea, which has been around for a number of years, and a drug called anagrelide which is probably a little less commonly used, because it has some more GI side effects and headaches associated with it. 

In some cases, especially in younger patients with this disease, we can consider using interferon, which is an injection of a cytokine, which are one of the chemicals that regulates the immune system within the body. But this interferon can actually help lower the platelets and there is a question of whether it may affect the biology of the disease as well. 

Katherine Banwell:

Let’s turn to polycythemia vera or PV, what are the different options available for treating it? 

Dr. Jeanne Palmer:

So, for polycythemia vera, everyone needs to be on aspirin. 

And additionally, everyone needs to make sure to keep their blood count low, to manage their hematocrit, which is one of the measures of red blood cells. So, in men it’s generally recommended to keep below 45 and in women it’s recommended to keep below 42 percent. Now, the studied number was 45 percent and that was a study that was done, I don’t know, it was probably about 10 plus years ago, that actually showed that by keeping the blood hematocrit less than 45 percent you reduce the risk of having negative events like cardiovascular events and heart attacks. Because women tend to run with a lower blood count than men, it’s been extrapolated that 42 percent should be the number used for women. 

Now, this can be done by phlebotomy, which essentially is bloodletting.  

It’s kind of like donating blood except for that the blood unfortunately can’t be donated to anybody, it has to be discarded. But the phlebotomy is one way to do that, and the reason that works is because it makes somebody iron deficient. So, whereas if this is normal, if you’re iron deficient you become anemic. If your baseline hematocrit is here, making you iron deficient brings you back to normal. So, even though we always associate iron deficiency with anemia, iron deficiency in the setting of polycythemia vera is actually kind of a treatment of sorts. 

Now, once somebody gets above 60 and 60 seems to be sort of the magic age in these diseases, once somebody gets above 60, it is recommended that cytoreductive therapy is used, which means therapy or treatment that will bring down the red count. And again, for this one, hydroxyurea is an option as well as interferon. And there is recently an approval, actually FDA approval for a newer interferon called ropeginterferon or Besremi, which can help just bring down the red blood cells but it is the first interferon that’s actually been FDA approved for this indication.  

Katherine Banwell:

Are JAK inhibitors used as well? 

Dr. Jeanne Palmer:

They are. So, if somebody doesn’t respond well to hydroxyurea, the approval for ruxolitinib is actually for patients who have failed hydroxyurea. Although it’s something that we often consider especially in people who have a lot of symptoms. So, the itching, one of the things that can really help itching actually is Jakafi. If people have night sweats, they have weight loss, spleen related symptoms, those are the patients that will benefit from Jakafi. Additionally, if they are on hydroxyurea and can’t seem to get control of their blood count, Jakafi is a good option to help control the blood counts as well. 

Interferon is a very nice option because there’s great data that shows that you may actually be able to lower the percentage of JAK2 burden. 

So, we’d look at something called an allele burden, which is the percentage of cells that are involved – have the JAK2 mutation. Now, we don’t know whether lowering this percentage necessarily translates to long-term better survival, but I think there is enough data out there, and there is a good biologic underpinning for saying that this actually can help. But yes, Jakafi is another thing. 

And the really exciting thing is that there is a newer agent called rusfertide, which is a hepcidin mimetic, which is basically taking a protein in your body that helps metabolize iron and by making it externally and giving it to somebody that it can actually help bring down the hematocrit without having some of the other side effects we know with some of the other medications. That is currently in Phase III studies, so hopefully in the next couple of years we’ll see approval for that. 

Katherine Banwell:

Oh, that’s great news. And finally, how is myelofibrosis treated? 

Dr. Jeanne Palmer:

So, myelofibrosis is a little bit of a different animal. When you have something like essential thrombocythemia or PV, a lot of this is managing symptoms, preventing blood clots, but if you do appropriate treatment and management of these diseases you could probably live close to a normal life expectancy. 

So, I never typically pin a survival on it. With myelofibrosis, it’s a little bit different because there is a survival. Instead of saying you can live close to normal life expectancy, it backs up to saying how many years do I think you can live with this disease. Now, of course, we are horrible at predicting how many years anyone can live, so we have to take that all with a grain of salt. But we can at least sort of risk stratify people. 

And the first thing that’s really important is to figure out whether somebody is a transplant candidate or not and if, based on age, disease risk features, stuff like that, or whether we think they ever will be a transplant candidate. So, that kind of helps us sort of think about what your path moving forward is.  

Now, the current FDA-approved treatment for myelofibrosis, there are three JAK inhibitors approved, which is like Jakafi, which was the first approved one but there is also Inrebic or fedratinib and Vonjo or pacritinib and these have all been approved over the years. 

The role of JAK inhibitors and treatment of myelofibrosis is symptoms-based. So, for example, a lot of patients with myelofibrosis will have weight loss, night sweats, big spleens, really feeling fatigued and poorly and in this setting, the JAK inhibitor can be very helpful. And you don’t have to have a JAK2 mutation, a lot of times people say, well, I don’t have the JAK2 mutation so how can a JAK inhibitor help. So, the JAK inhibitor works on this pathway, which is called the JAK/STAT pathway, irrespective of mutation. 

So, if you are having symptoms and you have myelofibrosis, JAK mutation, excuse me, the JAK2 mutation does not predict who is going to have a response. And people who, regardless of which mutation you have, may actually benefit from it. 

So, the JAK inhibitors, though, are extremely effective at reducing symptom burden as well as reducing the spleen size. And we know that if a spleen is big and we can make it shrink that, that probably is a surrogate marker for living longer, and I think it’s because inflammation does a lot of wear and tear on the body. So if you can reduce the inflammation and the spleen shrinks, which generally go hand in hand, then you might help somebody live longer. It is not changing the biology of the disease, though, however, it doesn’t change the pathway and that this disease is kind of projecting ahead in terms of creating – it changes, as it goes along, may acquire new mutations or something like that which makes the disease become more serious. 

Right now, the approved therapies for it are JAK inhibitors and the Jakafi, ruxolitinib was the first one approved. Inrebic was approved several years back, or fedratinib. 

And then the most recent one that was approved is Vonjo or pacritinib and that’s a drug that is a JAK inhibitor that is actually very good for people with low platelets. The reason I bring that up is because if we think of what’s the biggest limiter of JAK inhibitors, JAK inhibitors bring down red blood cells, and they bring down platelets. So, when somebody has low platelets it’s very hard to use a JAK inhibitor, because we’re not really able to increase the dose well enough to get that inflammatory reduction because of the fact that the blood counts will drop too low. 

So, now drugs like Vonjo exist which, due to several other mechanisms associated with the drug are actually much more tolerated in somebody with low platelets. So, if you have low platelets, you can actually take the Vonjo, hopefully get the same degree of JAK inhibition to help the spleen shrink, help the symptoms get better without necessarily making the platelets substantially worse. A lot of times they do drop, it doesn’t help bring up the platelets, but it does help people tolerate more JAK inhibition, which ultimately will help with symptoms.  

Dr. Jeanne Palmer:

So, one thing I also wanted to add about myelofibrosis treatment is sometimes people present, they don’t have a lot of symptoms, they don’t have a lot of spleen related problems but they have anemia or low blood counts and these can be incredibly hard to treat. 

Even with symptoms and low red blood cell count or anemia or low platelets, it can be challenging to treat because many of these medications lower that. To treat the anemia there are several things that we can do. One of the first ones is using erythropoietin, and so there are many agents, they go by the names of like Procrit or darbepoetin alfa (Aranesp), that actually stimulate red blood cell growth by – like we give a recombinant hormone that helps red blood cells grow. This is normally something produced by the kidney. 

So, one thing that’s important before going on one of these injections is to make sure that the kidney is not already producing enough. So, for example, if the kidney said, oh geez, I really need more red cells and is making lots of this hormone, erythropoietin, giving more of it is not going to help the system. But in people who don’t have a really high level it can be very beneficial.  

The other thing that can help with anemia, specifically, is a drug called danazol.  

It’s been around for a very long time. There are multiple presumed mechanisms of action, but one of them is that it is kind of a testosterone derivative. So, this is a medicine that can often help increase red blood cells in probably about 40 percent of people, and it’s a pill that you take twice a day. 

Another option, sometimes we use thalidomide or lenalidomide (Revlimid). These are medications that have been used quite frequently in the setting of multiple myeloma and even a little bit in myelodysplastic syndrome, so some other blood disorders.  

But in the setting of myelofibrosis, they can be helpful with anemia and sometimes are combined with prednisone or a corticosteroid. 

And then finally, in terms of drugs that are being tested and hopefully will be approved at some point in the future. There is a drug called momelotinib, which is another JAK inhibitor that actually has some mechanisms that may also help improve hemoglobin.  

So, this is something I’m really looking forward to and we anticipate may be approved by the end of the year. And finally, there is another drug called luspatercept. Luspatercept may work in the setting where your kidneys are already producing enough erythropoietin. So, the luspatercept is an injection that you receive once every three weeks.  

It is currently FDA-approved for the treatment of myelodysplastic syndrome but this is something that has been shown to have some efficacy in myelofibrosis as well. So, this could be another therapeutic option for patients with myelofibrosis. 

It is also important, especially for people who have polycythemia vera myelofibrosis to make sure that your iron has been checked and B-12 has been checked, because just because you have a bone marrow disorder doesn’t necessarily mean you don’t have a nutrition deficit that may be able to help improve your hemoglobin somewhat. But these are important things to talk to your doctor. I do not recommend just starting to take iron or B-12, however, if you’re anemic because in many cases you are not deficient and taking too much iron can actually be damaging.  

Katherine Banwell:

Yeah, that’s great advice.

Thriving with an MPN | What You Should Know About Care and Treatment


Transcript:

Katherine Banwell:

Would you walk us through the common symptoms of each of the MPNs? Let’s start with essential thrombocythemia. 

Dr. Jeanne Palmer:

Right. So, there are a number of shared symptoms throughout all the diseases and when we start to figure out how to categorize them, they call into several different categories. The first one is inflammation-related symptoms. We know that the inherent pathway that’s dysregulated or that causes these diseases to happen can also result in significant inflammation in a person, that can result in things like fevers, night sweats, weight loss, and overall feeling really fatigued and poorly, which is something that it seems to be much more prevalent in patients with MPNs, all sorts of them, actually. 

The next set of symptoms is related to microvasculature, so all the little blood vessels. And sometimes we think, oh, maybe that’s because there’s too many red blood cells or platelets and the blood become viscous. It’s probably more related to the actual dysregulation of that JAK2 pathway, which is inherent to all the myeloproliferative diseases and as a result, the little blood vessels can clamp down and that can give people headaches, visual changes, numbness and tingling in the hands and feet, and even can cause sort of a painful rash called erythromelalgia in the body. 

So, these are things that can happen that are probably less appreciated side effects of the disease. And finally, there’s spleen-related symptoms. The spleen is in the left upper quadrant of the abdomen and it’s an organ that generally is about 12 centimeters in length, 10 to 12, but in patients with myeloproliferative diseases it can be enlarged. And as a result of an enlarged spleen people can have feeling like they get fuller early. So, if you’re eating a meal, all of the sudden you can only eat half of that meal versus the whole meal. 

Discomfort or pain in the left upper quadrant. Sometimes it’s much more noticeable when you like bend over to tie your shoes. And then sometimes people can actually, when the spleen gets really big, the blood flow can be impaired towards the end of it which can cause some of the spleen tissue to die, and that can be painful. So, these are things that if somebody does start to notice that they’re having fullness in the left upper quadrant, pain, stuff like that, that that may be related to spleen symptoms.  

Katherine Banwell:

What about PV or polycythemia vera, what are the symptoms? 

Dr. Jeanne Palmer:

So, all of these sorts of relate to all of the myeloproliferative diseases. So, one other one that I didn’t mention, and this is actually more in PV than others, is itching. Itching can be absolutely unbearable when somebody has PV. It’s particularly noticeable after taking a shower. So, a lot of times I’ve met patients who are like I haven’t been able to take a shower in years, because it causes such a high degree of itching. 

Katherine Banwell:

Why a shower? Is it different from having a bath?  

Dr. Jeanne Palmer:

Water on the body that can cause the problem. So, if people take hot showers, it’s even worse. Although I think that people sort of react to it differently. Usually what patients end up doing is more like sponge bath type of things, rather than actually being exposed to the water. 

 Taking colder showers or cooler showers can sometimes help mitigate that. But the itching, and even in the absence of a shower, people can have pretty severe itching, and that can also be one of the major side effects.

Katherine:

Hello, and welcome. I’m Katherine Banwell, your host for today’s webinar. This program is part of our Thrive series. And, today, we’re going to discuss navigating life with an MPN. Before we get into the discussion, please remember that this program is not a substitute for seeking medical advice. 

Please, refer to your healthcare team about what might be best for you. Well, let’s meet our guest today. Joining me is Dr. Joseph Scandura. Welcome, Dr. Scandura, would you please introduce yourself?

Dr. Scandura:

Hi. I’m Joe Scandura. I am Associate Professor of Medicine at Weill Cornell in New York City. I am a Physician Scientist. I actually run a lab studying MPNs and hematopoietic stem cells. And I am Scientific Director of the Silver MPN Center at Cornell.

Katherine:

Thank you so much for taking time out of your schedule to join us today. We start all of the webinars in our Thrive series with the same question. In your experience, what do you think it means to thrive with an MPN?

Dr. Scandura:

As a goal, I think it’s very simple, symptom-free and normal life expectancy. Thriving with an MPN is living your life as though you didn’t have an MPN.

Katherine:

And one part of thriving with an MPN is finding a treatment approach that manages your disease, the symptoms of your MPN, and that fits with your lifestyle. So, what are the factors that are considered when choosing treatment for patients with ET, PV, and MF?

Dr. Scandura:

Certainly, the goals of the therapy. So, is the therapy one that I would be looking to maybe delay progression or for long-term potential benefits, or is it something I need now to control short-term risks such as blood clots? The goals of the patient because some therapies may be more suitable to the goals of one patient than another. 

And the other – you know, there’s clinical features that may kinda push towards one approach versus another. Certainly, in a 20-year-old patient, I’m thinking about fertility. I’m thinking about a normal life expectancy. In a 90-year-old patient, I have a different set of concerns, multiple medications – what am I going to do that might be affecting their other comorbid conditions?

Katherine:

Right. Right.

Dr. Scandura:

I think about what are my near-term and long-term goals. So, obviously, age becomes a factor there. If I’m 95 years old, no matter what I do that person is not going to live 20 years. If that person’s 20 years old and they’re not living 30, 40, 50, 60 years, that’s a real shame. That’s a huge loss of life. So, that helps kinda point me in one direction or another. 

And, then, there’s different types of therapy. There are injectable agents. There are pills. There are drugs that have been used for a long time but don’t really have an FDA approval. There are drugs that are approved for certain indications. 

And, as physicians, we can sometimes stretch that based upon clinical judgment. So, I think a lot of that goes into the discussion I have with patients about therapy.

And that’s always – you know, I present to them what the options are, what I think the benefits might be, what the potential toxicities are, and then we discuss.

Katherine:

Right. I would imagine monitoring patients is different for each of the MPNs. So, how are patients typically monitored over time, and let’s start with essential thrombocythemia? 

Dr. Scandura:

Yeah. I think – again, it’s similar. You know, what’s near-term, what’s long-term? And so, in all of these diseases, thrombosis risk is a near-term risk. That’s something that I am monitoring in certain ways to help mitigate that risk. In ET and PV, I approach them similarly. Blood counts are certainly – these are diseases of the blood forming system. Certainly, monitoring blood counts I find helpful. But the reality of it is, in ET, there is not a clear linkage between blood counts and risks. 

And so, I like to keep the platelet count near normal if I can. But I also recognize that it may not be worth suppressing all of the blood counts to achieve that landmark, because it’s not clear that that’s really reducing the risk any more than just having somebody on a medication that helps control the blood counts. In polycythemia vera, different blood counts are very important. The red blood cells are kind of like part of the clotting risk. We know from clinical trials that keeping the red blood cell parameters within certain ranges reduces the risk of clotting. And so, what I monitor in polycythemia vera is the hematocrit. In women, I like to keep it below 42. In men, I like to keep it below 45. 

But I don’t just – I’m not a slave to the hematocrit. I am keeping an eye on the other blood counts and the other red blood cell parameters. So, for instance, what’s the size of the red blood cells? That tells me a little bit about what’s going on in the blood formation for that patient. And what’s the number of red blood cells? So, sometimes people can have very small red cells, because they’re a little iron-deficient and have a huge surplus of the number of red blood cells. And that tells me a little bit about how their blood forming system is responding to therapy. 

Iron deficiency in polycythemia vera is very prominent. I personally believe it’s a very major driver of symptoms in patients who are receiving phlebotomy as part of their care. And it’s something that I monitor and really counsel patients on. My goal is to make phlebotomy independent, but it can take a while. 

Everybody starts out iron-deficient, and then we take iron out of their body through blood with the phlebotomy. And that makes them more iron-deficient. 

Katherine:

Right.

Dr. Scandura:

I monitor symptoms from patients, and sometimes that can tell me that their disease needs to be – their treatment needs to be tweaked a little bit, even something as simple as aspirin. People can sometimes have burning in the skin or itching that is sometimes responsive to changing the aspirin dose or how it’s given, once a day versus twice a day. 

And that simple thing can be a big change for a patient who’s kind of, literally, climbing out of their skin or wishing they could and to try and find something that is helping.

I had a patient the other day. He had COVID. I said, “Oh, you should probably get this medication.” Do you have your primary care physician? Who’s taking care of you?” And he goes, “Well, to be honest with you, you’re my guy.” And so, it’s true. I see this patient a lot. And so, sometimes they forget. If I’m not paying attention to their blood pressure, the risks or treatment of diabetes, cholesterol, lipids, their screening programs for mammogram or colonoscopy, health maintenance issues, I do keep an eye on that in patients, because I do think it’s a part of the MPNs. 

I think that there are excess risks for patients for some of these factors. Certainly, if you think of it as three strikes, they get a strike for having an MPN. I don’t want them to have any other strikes. So, diabetes, hypertension, those are strikes that I can potentially, at least, treat or refer them to somebody to help comanage with me. And so, that’s kind of my general approach.

Katherine:

What about patients who have myelofibrosis? Are they monitored more closely?

Dr. Scandura:

Yeah, I think it depends a little bit on the patient. Patients with early myelofibrosis often don’t have any symptoms or near-term risks much different than those from ET or PV. As the disease can progress, then some of these patients have more profound problems with symptoms, which I may be trying to find a solution to make them feel better. And also, blood counts can become more of an issue. 

Transfusions in some patients who are very high white blood cell count, the spleen is often quite enlarged. Although, in my experience, most patients aren’t really bothered by the size of their spleen as the physicians are. But it is something where I think, on average, they’re monitored a little bit more closely to quite a bit more closely depending on the patient.

Katherine:

Yeah. You mentioned blood counts. And we know that lab results can fluctuate a bit. What happens if someone suddenly has a change in blood counts? What do you do?

Dr. Scandura:

Yeah. I mean, repeat it. That’s the first thing. Also, check what’s going on. It’s not uncommon in patients with MPNs that I’ll see them and the counts are a little bit out of whack, the white count is much higher than it’s been, and questioning them. “Oh, yeah. I had X, Y, or Z last week or the week before.” It used to be a upper respiratory tract infection, or they had a minor surgical procedure. 

And sometimes the responses to these things can be accentuated in patients with MPNs. And so, if that’s what of this story, I certainly would repeat it and let things calm down a little. And that’s often all it is. I’m much more of a monitor of the trends. So, one-time measure doesn’t generally excite me. It might make me want to have a follow-up a little more – in a shorter period of time. Of course, it depends on what the change is. But, for most of the changes that we observe, they’re relatively minor. And I will monitor them over time. 

If I see a trend where something is progressively increasing or decreasing over time, then I start thinking about what else is going on. And that’s always in the context of what’s going on with the patient. How are they feeling? What’s their physical exam like? What are the other laboratory values like? 

Katherine:

When is a bone marrow biopsy necessary?

Dr. Scandura:

I would say a bone marrow biopsy is absolutely necessary at the time of diagnosis. I personally do not routinely monitor by bone marrow biopsy unless it’s part of a clinical trial. 

But I do perform a bone marrow or want to look at the bone marrow morphology if there is one of these changes or at least a trend that I want a little bit more information about. And so, if – or if it’s been a very long time since somebody has had a bone marrow. If it’s been five or ten years, then sometimes I may recommend we look just so we can collect a little bit more up-to-date information. 

But I don’t routinely do a bone marrow, but I will do it if there are laboratories that are kind of trending in the wrong direction, there’s symptoms, there’s physical findings that I’m just not sure about. And I think it would help me be more sure as to what’s going on and be able to discuss that with the patient. Sometimes, just to say, “Hey. Look, we were worried about this, but the bone marrow looks really good.” 

Katherine:

Yeah. Can you talk about shared decision-making? Why is it so important for patients to work closely with their healthcare team on choosing a therapy?

Dr. Scandura:

Because these are therapies that last for a long time. And, hopefully, the patients and the relationship last for a long time. And so, I think that everybody has to be comfortable with the decision about a therapy. And my personal goal is to try to make sure that everybody understands the rationale for a therapy, the potential ups and downs with the therapy, which every drug has, every approach has, and what I’m kind of watching and monitoring. I’m a very – I think that communication relieves a lot of anxiety. I think that the unknown is far scarier than the known, even if it’s not perfect. And so, I think shared decision-making has a role in relieving some of the scariness of unknown. 

If we’re discussing to come to a decision, that means that my job is to give you the knowledge that I have so that you can tell me the knowledge about you and what you’re feeling and what you want back. And that back and forth is what helps me do a better job of taking care of the patient and helps the patient understand what’s going on and relieve some of the stress of the unknown. So, I think it’s a very synergistic approach. I don’t think I could practice medicine in another way.

Katherine:

Dr. Scandura, much of our MPN community is highly engaged in their care. What are some educational resources you would recommend for people who are seeking more information about their condition?

Dr. Scandura:

I think that there’s some basic information available from a variety of – for instance, the National Cancer Institute has some basic information. Leukemia & Lymphoma Society has some basic information. 

The MPN Research Foundation has some basic information. And then there are some information websites that are run by corporations, which are – I think they try to be even-handed in some of the discussion and has some good information there, too. I think the – none of these is a perfect source of information. I don’t think there is one source that you can go to answer every question that you could ask. 

My MPN Center has a website with a bunch of QAs, and we just every now and then add a new one. And it’s just a really long list. So, these are questions our patients frequently ask us, and we sort of put answers there to help guide. But individual details are often more important than sort of generalizations. I find patient – go ahead.

Katherine:

Oh. I was just going to ask, what about the forums, patient forums that are available? Is that something you would recommend? 

Dr. Scandura:

What I kind of I find my patients do is they’ll go out and look for information, because patients with MPNs, thankfully, tend to live a long time. And they are often curious about their disease and want to do better and figure out how they can do better. And so, a lot of them will go to whatever sources are available. But, generally, they come back. So, we circle back; we regroup. And sometimes, it’s la-la land, a little bit crazy things, and sometimes it’s really interesting. 

I learn a lot, you know, what’s going on in terms of what are patients really reporting, because sometimes in a clinic visit people kind of don’t say everything, or they forget to say something or maybe just my experience. I don’t see every patient in the world, right? So, if it’s something that’s relatively rare, then I may not have seen it with a new drug or something like that. 

So, I can learn from that experience as well. So, I think it’s kind of like people go out. They can be like little honeybees and collect all the information from all the flowers out there. And then they come back, and we regroup in the nest. And we discuss and decide what makes sense, what’s relevant to them, and what might help with our decision-making.

Katherine:

Yeah. Managing the worry associated with a diagnosis or concerns even about progression can lead to a lot of anxiety and fear amongst patients. Why is it important for them to share what they’re feeling with their healthcare team?

Dr. Scandura:

I would say this. If our goals are to have people – I mean, this is what I say to patients – I want you to think about this disease when you’re here. And, then, when you’re not here, my goal is to have you not thinking about this disease because you’re feeling okay and you’re comfortable and confident in what’s going on. 

So, I want to make it a clinic visit disease. That’s not always possible. But, for many patients, it is. I don’t want somebody to become – to start thinking like a sick person when they’re not. I don’t want the diagnosis to be the disease, right? I want the person if they’re feeling well, to recognize that. Live your life; move on with things. But, at the same time, these kinds of diagnoses are scary. 

Katherine:

Yeah.

Dr. Scandura:

And so, it is normal with a new diagnosis or a change in the diagnosis to go through a period of time where you have to adjust. And so, that’s normal, and you have to work your way through it. Some people want to work that all out internally, and that’s good to a certain extent as long as they have good supports at home. But I often want to know how they’re doing, how they’re working through that so I can get a gauge of how it’s affecting their life and the duration where this adjustment is going on. 

So, somebody who’s still adjusting to a new diagnosis two years after the diagnosis, and they’re otherwise clinically well, that’s getting into the range where it’s not normal. You might need additional help. You might need counseling. And, in some patients, that might include some medications for a short period of time. The goal is to have the disease affecting you only in so far as it’s affecting you, not the idea of the disease.

Dr. Scandura:

So, that’s a – again, it’s a conversation. There are lots of resources. People, being individuals, deal with things in their own way, and I just try to help understand with them how it’s affecting their life. And, if it seems to be more than I would expect, I’ll tell them that. 

And then we can discuss that. It doesn’t mean we have to do something today, but I will tell them, “I think this is maybe a little bit more. Why are you so worried? I think you’re doing great.”

Katherine:

Yeah. Yeah. Can a social worker or somebody else on the healthcare team help with these emotional needs that patients have?

Dr. Scandura:

Absolutely. We have great social workers. I tap into them all the time. We also have a group of psychiatrists who are really interested in kind of psychiatry that’s related to oncology and the diagnoses and how it impacts care. I mean, this is New York City, so everybody has a therapist. But a lot of patients have preexisting connections to healthcare providers or support systems. I think, for some patients, groups are helpful.

Katherine:

We’d be remiss if we didn’t bring up financial concerns, treatment and regular appointments can really become quite expensive. Understanding that everyone’s situation is different, of course, where can patients turn if they need resources for financial support?

Dr. Scandura:

Yeah. It depends on what the issue is. So, one of the biggest areas that I found this can interfere with care is when we have copays that are really not reasonable and not affordable. And so, how do we fix that? How do we get access to an agent that might be beneficial for a patient but that – you know, and the insurance has approved it, but they’ve approved it with such a high copay that it’s just not an option anymore. 

And so, there are foundations. The PAN Foundation, we often will reach out to for copay assistance. And, actually, many companies have copay assistance programs for their individual drugs. And so, we have some of our nurses who are quite good at navigating these different agencies, and some of them are kind of drug-specific. 

And because we see a lot of patients with MPNs and the number of drugs is not that great, we’re pretty tapped into what are the options for copay assistance that might be helpful. And it often works. It doesn’t always work. I had a patient I saw pretty routinely, and I kind of like my certain group of labs that kind of make me feel like I have a good sense of what’s going on. But he was getting killed with the lab costs. And he mentioned this to me, and then I have to do what I tell my – I have three teenage daughters, right? And, when they were littler – smaller, younger, we spent a lot of time distinguishing needs from wants, right? 

So, this was one of those instances. What laboratory do I need to make sure that this patient is safe? What do I want because it makes me feel like I have a better idea of what’s going on? And maybe I can back off on those wants if I’m seeing the patient pretty frequently, which I happen to be at that time. And so, some of that is a conversation. 

And it depends on the specifics of the insurance and a little bit of back and forth and knowing how to kind of minimize that financial burden when that’s starting to compromise care.

Katherine:

Yeah. Let’s answer a few audience questions that we received in advance of the webinar. This one is from Sophie, “What complications can arise from an MPN during pregnancy?”

Dr. Scandura:

Well, look, pregnancy – here you have two things, one of them common and complicated and the other one uncommon and complicated. So, common is pregnancy, but every pregnancy is different. And there’s a lot of changes going on in the body, and there’s certain risks that can go along with that as well. So, clotting risks sometimes can be increased in pregnancy. And then you have an MPN, where you have a clotting risk on top of that. The pregnancy really changes what kinds of medications we can think about using. And so, there are certain medications that we use comfortably in patients that would be an absolutely forbidden medication in a pregnant woman. 

And so, it depends a little bit on what’s going on with the patient. But, if they have a history of clotting, then certainly, we would think about wanting to control the blood counts. It depends a little bit on what the disease is how we would do that. Interferons are commonly used in pregnancy, and they are safe in pregnancy and can improve the outcomes in some patients with pregnancy. 

But short of that, in patients, for instance, who are very thrombotic risk, sometimes we have to sort of balance the risk of having a clot and something that can interfere with the pregnancy and the risk of bleeding. So, it’s not uncommon that people are on blood thinners during pregnancy at some point, but it really depends on the individual patient. What we do here is we keep very close contact with the patients. 

And all of our patients are seen by the high-risk OB/GYN. So, it’s not the general obstetrics people who are monitoring the patient, so they’re much more closely monitored for complications of pregnancy. And we are seeing them more frequently during pregnancy to help, from the MPN side, to try to optimize and minimize the risks of clot. And that doesn’t end as soon as the baby’s out. If breastfeeding, their clotting risk is not normalized after pregnancy, as soon as the baby comes out. And so, you know, there’s an adjustment for several months afterwards where we’re still kind  of thinking about this person a little bit differently than we would if they were not or had not been recently pregnant. 

Katherine:

Yeah. We have another question. This one from Jennifer. She wonders, is there research being done on MPN progression to understand how it happens or even prevent or slow progression?

Dr. Scandura:

Yeah. There’s a lot. I think there is a – from both the sort of basic laboratory using animal models to try to understand what are the kind of systems that are involved in how these diseases change. What genes are involved? How do they talk to each other? You know, these are not cells that live in a vacuum, right? They live in a special microenvironment. What are the signals that crosstalk between the MPN cells, the MPN stem cells, and their microenvironment? 

And so, there’s a lot of research on that and the basic side of things. In humans, there’s a lot that has been done over the years in terms of trying to understand what are some of the genetic features of progression. And I think we’re beginning to get a little bit of a better understand of what are the non-genetic things that are associated with progression. 

I was part of an effort from the MPN Research Foundation and still am. They have what they call the Progression Network, where they tried to put together a number of investigators from really across the world to share ideas about the nature of progression and how we might look at studying this and understanding ways to prevent progression. 

I think we do have some drugs now that show some promise in terms of being able to prevent progression. I think interferons have shown this in polycythemia vera in terms of a promise for improved long-term outcomes and delayed risk progression. I think that the gold standard randomized trials are maturing and are sort of bearing out some of the same findings that have been observed retrospectively, so sort of kind of looking back in time. 

But the difficulty is that it can take a long time for patients to progress. And you say, “Oh, that’s great.” And that is great. But, from a research – from a statistical side, it means things are really slow. If you have to wait 15 years to assess whether or not people progressed less in one treatment versus another, it’s really slow going. And so, we have to do a compromise of what’s – you know, what do animal studies say? What does retrospective analysis, when we might have people who started treatment 30 years ago, and now we’re just seeing how did it all work out? It’s not a perfect study, because biases can creep in, but it’s what we have now. And so, there’s a lot. And I think, increasingly, progression is being recognized as a goal of therapy, to prevent progression. 

Personally, it is one of major goals, because I think we do a pretty good job at preventing clots with available treatments. But I don’t think we do a very good job at preventing progression, mostly, because we don’t exactly understand what’s driving that. And so, I think until we develop that deeper understanding and really invest the time and effort in terms of learning which approaches can help prevent progression, we’re going to continue to have these questions.

Katherine:

Yeah. Well, thank you for those answers, Dr. Scandura. And please continue to send in your questions to question@powerfulpatients.org, and we’ll work to get them answered on future programs. As we close out this conversation, Dr. Scandura, I would like to get your thoughts on where we stand with progress with MPN care. Are there advances in treatment research that you’re hopeful about?

Dr. Scandura:

Yeah. I think it’s a very exciting time, actually. I think that over the past 5 to 10 years the amount of new drugs that have been developed and tested in patients has grown exponentially. The number of companies that are targeting MPNs for their drug development has expanded dramatically. The number of clinical trials, good quality clinical trials has increased dramatically. And I think the success that’s coming out of that is we start seeing drugs now that are looking to be very, very effective. I don’t want to name individual drugs. 

But I know we have a number of clinical trials where we’re seeing things with these agents that we haven’t seen with our traditional therapies, meaning changes in the bone marrow that we haven’t seen before or a normalization of symptoms or blood counts in an area that has been challenging in the past. And so, we now have drugs and a number of drugs going for approval, a number of newly-approved drugs, even interferon, which is a drug that’s been around forever. Well, not forever. But, I mean, I guess forever, yeah, because it’s a natural product. 

So, as long as there have been humans, there have been interferons, even before humans. But now we have it. As a pharmaceutical, they’ve been around for decades. And we now have the first – even though we’ve been using it for decades, we have the first approved, FDA-approved interferon for polycythemia vera, which is I think a huge change. 

A company invested the money in getting FDA approval for an agent, and that means they have to – the bar’s higher, and they have to prove something that just using it off-label hasn’t. So, I think it’s a tremendously exciting time. I expect it’s going to continue. We’re going to continue to have improvements in care. There’s going to be combinations of drugs. I think that we’re going to see real advances over the next 5 to 10 years.
