Katherine:

So, the symptoms of myeloma, as well as the side effects of certain medications, can vary greatly among those being treated. How do you approach symptom management with your patients?   

Dr. Ailawadhi:

It is extremely important that we focus on the symptoms, whether it’s coming from the disease or it’s coming from the treatment. Because frankly, if a person is responding to the treatment, you want them to stay on the treatment for a longer duration of time, so the disease can stay controlled.  If we don’t handle the symptoms from the treatment or the side effects that are happening or if the disease is causing too many symptoms, it is more likely that either we’ll start cutting down the drug too much or stopping the treatment, et cetera, and then the disease just comes back. In some cases, that is necessary, but generally we would like to modulate the treatment or address the symptoms.  

So, one important piece that we should do, or at least we try to do over here, is that every single time that we talk to the patient for any of the visits – while there is enough time spent on, “Well, these are your labs, your diseases responding markers, SPEP, and M spike, and light chain,” and all that stuff – we spend a lot of time asking about symptoms.  

It is, I understand, challenging to cover everything, but to familiarize what drugs cause what kind of symptoms, and at least making sure that we ask those from the patient.  For example, IMiDs like lenalidomide (Revlimid) can cause some diarrhea, can cause fatigue, can cause sleepiness. Well, I must ask about diarrhea from all my lenalidomide patients.  

Bortezomib (Velcade) can cause neuropathy.  It can give rise to shingles. I must ask my patients for every bortezomib-treated patient. “Hey, do you have any neuropathy numbness, or tingling?  

Are you taking your medication to prevent shingles, et cetera?” I’m just saying we may not be able to do a comprehensive review of every single symptom from every single patient, but whatever the target side effects are important to know every single time. We educate the patients about these side effects so that they are aware of them, and they can report these side effects. And then, if the side effects are happening, any symptoms are happening, then is it to the point that we need to stop the treatment?  

Frequently, we do take drug holidays for a few weeks just to make sure, okay, we know is it coming from the drug or the disease? And every now and then, we realize, well, the drug was not even causing the symptom, because we stopped it, and the symptom stayed. Or so then, why stop the drug? There’s no point stopping it if I can’t control the symptom.

So, understanding whether it’s coming from disease or drug or something else, addressing them, making the changes appropriately to lower the dose, space them out, et cetera. All of that is done. And of course, like I said, importantly, educating the patient is so very important. I’ll add one quick thing. We focus on the drug-related effects.  

As you rightly mentioned, Katherine, the disease itself can cause a lot of symptoms. So, generally, when I see a new myeloma patient, in the first couple of visits, we’ve done all the testing, we’ve discussed the treatment, and we’ve addressed some of the basic symptoms like pain, for example. That is big in myeloma.

But then, when the patient has started treatment, generally within the first two months, the focus that our clinic has is we need to control any side effects, and we need to address any symptoms that are being left over from the disease. And that’s when we start referring patients to interventional radiology for any bone procedures or palliative care for pain control or neurology for neuropathy, whatever so that we are controlling all the symptoms.  

And that’s when we hopefully get the patient as close to their baseline as possible.

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.  

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.

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.

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:

Dr. Ramaswamy, along with treatment can also come side effects. What are some common side effects of breast cancer treatment?

Dr. Ramaswamy:          

Yeah, great question. Again, an important question for you all to consider. So, let’s divide our treatment  to targeted therapy and chemotherapy. The targeted therapy could be the estrogen receptors and then the  HER2 because the HER2, again, remember that biomarker. And then the chemotherapy that any patient with breast cancer could get, including, of course, the triple-negative. And then we’ll touch base  a little bit later on with the immunotherapy. So, when we look at the targeted therapy with estrogen receptor, anti-estrogen receptors, of course, it’s like putting you into menopause again. It’s like so you could have hot flashes, you could have some emotional liability and you could have vaginal dryness and sexual libido could be lower.

And also you could have joint aches and pains and your bone density could go down and cause osteopenia and osteoporosis and fractures. So, those  are some of the – and we can address all of those that we’ll come to later. With the HER2-targeted therapies, one of the main things will be the heart. These can affect the heart because there are some receptors that are present there that these HER2 therapies can affect the myocardial function. So, they don’t cause increase in heart attacks, but just the pumping action of your heart could go down. We keep checking your heart function to help with that. And then with the chemotherapies, other than your blood counts going down, these are acute events. Those blood counts could go down, which could put you at higher risk for infections. Again, some of the heart chemotherapies can affect the heart. So, we’ll keep an eye on that.

And, of course, fatigue that comes with all of these treatments that can happen. But some of those chronic things that can happen is also neuropathy. So, tingling, numbness in your hands and feet, even sometimes pain in your hands and feet. And then this can stay on for a little bit longer and can cause some trouble buttoning your shirt or playing the piano or putting your earrings. So, it can affect your  daily quality of life and cause pain. The other important thing, which we do have now an option is  also hair loss. I know that is something hard for age.  It’s so hard for women to lose hair and the consequence of being identified differently and not having that – when you look at the mirror, it’s a constant reminder.

So, we do have something called a scalp cooling that you could take an option and discuss with your doctors whether that how helpful that’ll be for your  type of chemotherapy and whether you could use it and you can – but 60 percent of the time not lose all your hair and need a wig. So, that is something that you can address. So, broadly, these are the issues that can happen. Again, this is very broad. Depending on your treatment, you still need to talk to your doctors.

Katherine:

How can some of these side effects be managed?

Dr. Ramaswamy:      

So, the key thing is to be first thing that I want to advise all our patients is that be vocal about your side effects. Okay? Sometimes we all think, okay, they did tell me I’m supposed to have all the side effects. I just need to keep quiet about it. That’s not what is important. And I think I did miss mentioning the GI tract changes like nausea, vomiting, or diarrhea. Again you think, oh, this is our part of all chemotherapy, I just need to keep quiet. No, that’s not the case because we actually give you anti-nausea medications before the   chemotherapy. So, if it’s not effective, you need to have to tell your doctors, “Okay, this time I had a couple of sensations of nausea, but no vomiting.”

Or “No, I was vomiting a lot.” Whatever it is. Even if you had just nausea, it’s important to tell your doctors. If it’s diarrhea, you need to tell them. We do give you some medications, but if it’s not working, you need to tell them. And again, we always underplay the issues with sexual side effects because you don’t want to talk about that. I mean, it’s not important. No, it is important.

It’s important for your intimacy, it’s important for your life, and it’s important for you to speak because there are supportive care therapies that we can provide. Neuropathy, again, I think your doctors will always ask you, but being vocal about it, being honest about it, and talking about it is important. So, again, fatigue.

They are going talk to you about exercise, because exercise does overcome that fatigue. But if you’re not able to do it again, it’s honest to say, “No, but I didn’t do what you said last time.” So don’t feel bad about it. And there could be other ways we can improve your fatigue too. So, again, sharing those side effects is important and we can. We can address all of these side effects. Now, I’m not saying the minute we address these side effects it’s all going to go away completely, but they can get better. And it’s important for you to talk about it and  get those supportive care measures.

Transcript:

Katherine:

There are a lot of available therapies for myeloma. And I’m wondering what factors might impact treatment decisions. You did mention comorbidities. But what other factors are there?   

Dr. Derman:

Sure. And I think in part, it depends on if we’re talking about induction therapy or in the relapsed refractory setting. Let’s focus on induction therapy, right?  

So, there are some drugs that we’re typically going to employ pretty much universally. For those who are inclined to use that CD38 monoclonal antibody that I mentioned, it pretty much plays well with patients of all walks of life. So, that’s one where I feel really comfortable regardless.  

Lenalidomide is a drug that we don’t necessarily know from the get-go if there’s going to be a patient that’s not going to tolerate it well.   

We might reduce doses up front. But for the most part, that’s another drug that we’re typically going to use. I would say the one exception is for patients who have a simultaneous diagnosis of amyloidosis. And we know that in amyloidosis, lenalidomide may not be as well-tolerated.  

But actually, one of the key decisions that I’m often making in clinic myself is around that drug class that I mentioned earlier called proteasome inhibitors. And I mentioned two different drugs. There’s bortezomib and carfilzomib. And they actually come with very different side effects that I think are important to mention.  

Bortezomib is one that is typically associated with a high rate of numbness and tingling, what we call neuropathy in the fingers and toes. And about 75 percent of patients have been reported in the trials to get this. And most of it is what we call lower grade. But I’m not in the patient’s body, and I don’t know what that – what even a grade 1, which would be the lowest grade, really feels like. And if I have a mechanic, somebody who types for a living, a surgeon, somebody who uses their hands or their or rely on their feet for their day-to-day, that’s a scary prospect, right?  

The flip side is this drug, carfilzomib (Kyprolis), is one that does not really cause nearly as much neuropathy, but has been associated with cardiac effects. Heart issues. And so, that can scare people, right? Heart’s important I hear. So, we have to be really careful in how we pick these therapies and talk about it with patients.

Transcript:

Katherine:

What are the long-term effects of JAK inhibitors? And what happens when JAK inhibitors are no longer effective? 

Dr. Hobbs:

Yeah. Great question. So, so far the patients that have been on JAK inhibitors for a long time don’t seem to have the development of additional toxicities that we didn’t know about.  

So, I’ll just comment on some of the things that we do know about. Weight gain is a common complaint that I have from patients, especially those that have polycythemia vera, because maybe they didn’t want to gain weight when they were put on a JAK inhibitor compared to the myelofibrosis patients who maybe had lost a lot of weight before being on a JAK inhibitor.  

There are certainly higher risk probably of developing infections with some of the JAK inhibitors. And we see, for example, shingles reactivation being a common one. And there’s the concern of development of skin cancers, which has been seen with some JAK inhibitors. But generally speaking, long-term use seems to be safe. That being said, ruxolitinib (Jakafi), which is the oldest one to be approved, has only been around since 2011, so we don’t have decades worth of experience to know.  

When JAK inhibitors stop working – to answer the second part of your question – until fairly recently we really didn’t have a whole lot to offer because there was only one JAK inhibitor. Now we have two others. We have fedratinib (Inrebic) and also pacritinib (Vonjo). And we know from the studies that have been done with both of these agents that some patients that lose response to Jakafi, meaning that their spleen starts to grow or their symptoms start to come back, can be treated with these other JAK inhibitors.  

And many patients will, again, have control of their spleen and symptoms. Now losing response to a JAK inhibitor can come in many different ways. And so, some patients may also develop signs of having leukemia or progression of their disease to leukemia. And, unfortunately, for those patients, being on another JAK inhibitor doesn’t make sense. So, those patients may need to receive other types of medications or a stem cell transplant.

Transcript:

Katherine:

What about myelofibrosis, Dr. Hobbs? What advances are being made in the care of patients with this more advanced MPN? 

Dr. Hobbs:

Yeah. So, in myelofibrosis, I would say it is almost difficult to keep track of how many clinical trials are currently open. So, in 2011, we had ruxolitinib approved, or Jakafi. That was the first JAK inhibitor. Since then, we’ve had two more JAK inhibitors approved, fedratinib (Inrebic) and most recently pacritinib (Vonjo). And we’re currently awaiting the fourth JAK inhibitor to be approved, and that’s called momelotinib.   

And in addition to the JAK inhibitors, there are lots of other clinical trials underway right now that are either alone – a drug by itself or a drug in combination with ruxolitinib.  

So, there are several Phase III studies. And the reason why that’s important is that after Phase III we usually see a drug approval. So, we can expect, hopefully in the next couple of years, to see many more drugs available on the market to treat patients with myelofibrosis. Some of those include agents that block different pathways within a cell. And that includes a drug called parsaclisib. There’s a drug called pelabresib (CPI-0610), which is a BET inhibitor.  

There’s another drug called navitoclax (ABT-263), which is a cousin of venetoclax (Venclexta), which is a drug that we’ve been using a lot in leukemia. So, there’s lots of different drugs that are being used in combination with ruxolitinib. There’s also a drug called luspatercept (Reblozyl) that’s also been approved for myelodysplastic syndromes. And I suspect that that’ll be approved as well to help patients with anemia. So, really, there’s lots of drugs that are being studied right now. And I think the question that we’re all asking is, well, how are we going to use all of these different drugs? So, I look forward to seeing the results of those studies.  

Katherine:

Mm-hmm. Will some drugs work better for some patients and others not? 

Dr. Hobbs:

That is such a good question. And so, what I’m hoping to see is exactly that. I’m hoping to see that for patients, for example, with anemia, perhaps we’re going to be using luspatercept and momelotinib. Perhaps we’re going to see that patients with certain mutations may respond better to certain medications like the BET inhibitors or navitoclax or the PI3 kinase inhibitor, parsaclisib. But as of now, we don’t have enough information.  

We haven’t seen enough results of these studies to start to be able to know, you know, what is the patient that’s going to do better with two drugs versus one drug? And so, I think that over the next couple of years we’re going to start to have answers to those questions.

Personalized Medicine: Making Lung Cancer Treatment Decisions


Transcript:

Katherine:

I’d like to walk through the types of treatments that are used today to treat lung cancer. Let’s start with surgery.  

Dr. Patel:

We think about local therapies as things like surgery. So, surgery has evolved, again, significantly.  

Now with videoscopic approaches and robotic approaches we’re able to remove a tumor either with a larger incision – more traditional incision – or some of the smaller incisions. And the goal of doing the surgery is often to want to diagnosis the cancer. So, to do a biopsy. But when it’s used in terms of cancer treatment, the goal of surgery is to get a complete resection.  

So, we only do surgery if we can remove a tumor and mass with clear margins and not compromise other vital functions. Sometimes we’ll, again, do a more palliative surgery if we need to, if there’s a problem that’s causing significant symptoms. But in that case, the surgery is generally not improving the survival of the patient. It’s trying to palliate symptoms.  

Katherine:

Mm-hmm. What about other types of therapy? 

Dr. Patel:

Other localized therapies predominately include radiation therapy. And, again, radiation has significantly changed over the past years. We’ve been able to incorporate new technologies, truly target tumors, and to minimize toxicity, with two kinds of radiation. Photon therapy, which is more traditional therapy, and proton therapy, which we see administered in a very small subset of patients.  

Primarily, photon therapy, we treat tumors, sometimes over many weeks, to decrease toxicity versus sometimes we give one or two doses of radiation in a high-dose fashion that’s very targeted.  So, often for the chest in stage III cancer, for example, a patient may end up getting six weeks of radiation Monday to Friday with chemotherapy.  

And that, again, is curative intent. It’s to ablate the cancer and to provide the best local treatment. 

Often, we’ll do something called stereotactic radiation therapy. And that is if there is a discreet mass, often that could be if the cancer is metastasized to the brain, we can give very targeted radiation there, again, to ablate the tumor.  

In patients who may not be candidates for surgery because lung surgery is a big deal, right? Removing part of your lung can lead to morbidity in someone with other medical issues. Sometimes we can use pinpoint radiation in the lung and see really good outcomes for patients with good disease control.  

Katherine:

You’re also using chemotherapy still, I would imagine? 

Dr. Patel:

The other part of treatment for lung cancer are systemic therapies. And there a number of systemic therapies. So, I sort of break it down into three major parts. One is chemotherapy. Chemotherapy remains a backbone of treatment for lung cancer.  

It’s a lot more tolerable and much more personalized than ever before. Often chemotherapy can be given to patients without significant toxicities. Not everyone loses their hair. Not everyone has neuropathy. Often, I have patients who are working and taking care of their families on chemotherapy. So, it is a good and very reasonable option. But two things that we’re really most excited about – and I think have changed the field most dramatically – are targeted therapies and immunotherapies.  

Katherine:

Mm-hmm.  

Dr. Patel:

These targeted therapies are rationally designed molecules or antibodies that block proteins that may be overexpressed in lung cancer.  

So, some of them are the byproducts of mutated genes that are upregulated and causing a cancer to grow. Others may just be that we’re seeing a high level of protein expression on the cancer cell. But these targeted therapies preferentially bind to their targets that are present on cancer cells and not so much normal cells. Because of this, often there is less toxicity to normal cells. But because we can find specific targets – and the best targets are ones that are only expressed on cancer cells.  

But because we can find a direct target, sometimes we’re able to design drugs that may have significant efficacy. So, 80 percent or 90 percent of people who have a particular target and are able to get a targeted therapy may have a response to treatment. Targeted therapy can be great for some patients. And patients may be on oral medications, sometimes for years, to control their cancer.  

The other real game-changer in the past decade for lung cancer has been the integration of immunotherapy. Approved immunotherapies currently are primarily antibodies that we give to patients. And these antibodies block proteins that are expressed by cancer cells which downregulate the immune system. By shutting down these proteins, your own immune system is able to kind of re-see the cancer cell and kill it.  

And so, now we know in patients with more advanced disease that immunotherapy or immunotherapy with chemotherapy leads to better outcomes than we’ve ever seen. We also use immunotherapy for patients with stage III lung cancer after chemotherapy and radiation. And this improves their survival significantly.  

And most recently, we’ve now integrated immunotherapy after surgery for patients with early-staged disease to decrease their chance of relapse from cancer.   

Katherine:

So, are there options for relapsed patients? 

Dr. Patel:

So, absolutely. Most of our therapies in the metastatic setting work for some time. And then cancer is a difficult adversary. It figures out how to overcome whatever strategy we’re using and becomes resistant. When that happens, often we need to change course. We need to try a new therapy. We have a number of therapies that we’re looking at in the first- and second-line settings. And we’re trying to understand best therapies for subsequent lines of treatment.  

Generally, I say treatment is appropriate if you’re feeling pretty well, right? If you’re able to tolerate treatment, then the likelihood that you would be able to benefit from therapy is significant. How that changes over time weighs heavily on our decision. So, if someone’s having more fatigue or more symptoms from their cancer, it may be that even a little bit of toxicity proves too much.  

Whereas if someone is feeling still really good, we may be willing to say, okay, I’m going to take a little bit more of a risk for the benefit of improved cancer control.

Transcript:

Katherine:

What are the side effects that patients can expect with these treatments?  

Dr. Maddocks:

So, when they get the treatment, on the day they get it, there can be an infusion reaction to the rituximab or antibody therapies. So, the first treatment, that treatment is given very slowly and titrated up. If patients have a reaction, we stop it, treat the reaction, and then they’re able to continue therapy but again, that first day, it can take several hours for that one antibody to get in. And then, later, therapies are given at a more rapid pace.   

So, about 70 percent of people who react, it can be really almost anything. Some people get flushing, some people will get a fever, some people –have shortness of breath or their heart rate will go up. 

Katherine:

Okay. All right. Any other side effects? 

Dr. Maddocks:

Yeah. So then chemotherapy is meant to kill cells during the cell cycle. So, cancer cells divide more rapidly, chemotherapy is targeting them, but it also effects good cells in the body, specifically those that divide at a more rapid pace. The biggest risk of chemotherapy is infection.  

So, it effects the good white blood cells that fight infections. It can affect your red cells that carry your iron, gives you your energy. Or your platelets which help you to clot or not bleed when you get caught. So, infection is the biggest risk of chemotherapy. So, usually, with this regimen, that infectious risk is highest within the second week of treatment, that treatment is given every three weeks.  

So, we tell patients they should buy a thermometer, check their temperature, they have to notify their doctor or go to the ER if they have a fever. Besides infection, there’s a small percentage of patients who might need a transfusion. GI toxicity. So, nausea, vomiting, diarrhea, mouth sores, constipation, all of which we have good treatments for. So, we give medication before chemo to try to prevent people from getting sick and then give them medicine to go home with, if they have any nausea. We can alter those medications as time goes on, if they’re having any problems. So, we just need to know about it. Most patients will lose their hair with this regimen.  

It can affect people’s tastes, it can make their skin more sensitive to the sun, and then, less common but potential side effects are it can cause damage to the nerves. Or something we call neuropathy, which most often patients will start with getting numbness or tingling in their fingers and toes, and we can dose adjust if that’s causing some problems.  

And then, there’s a risk to the heart with one of the drugs. So, the heart should pump like this. The heart pump function can go down. So, we always check a patient’s heart pump function before they get their chemo, to make sure that they’re not at higher risk for that to happen.  

Katherine:

So, all of these approaches are used in initial treatment?  

Dr. Maddocks:

Mm-hmm. 

Katherine:

Okay.

Understanding Treatment Options for ET, PV, and Myelofibrosis


Transcript:

Katherine Banwell:

We received some audience questions prior to the program today. This one is from Jacqueline, “What can I do to minimize pruritus or itching due to PV? A typical histamine blocker like Claritin or Zyrtec has done nothing whatsoever.” 

Dr. Jeanne Palmer:

Yeah. Unfortunately, the itching of this is not as much mediated by an allergic type reaction or histamine. It’s a lot related to that microvasculature, those tiny little blood vessels. Things like avoiding hot showers, as we talked about, taking cooler showers or not even taking showers, just like cleaning yourself with a washcloth can be helpful. There are certain medications that we can use sometimes that help. 

Now, first of all, Jakafi is extremely effective for itching. Of course, it does have side effects. It’s not always approved for your disease, so for example, it’s not approved for essential thrombocythemia. But JAK inhibitors can be helpful in that setting. There are also medications like gabapentin, which is a medicine that we use to treat peripheral neuropathy and that can actually be helpful because actually the itching, a lot of it is related to nerves not functioning right, so gabapentin can be helpful. 

And a really old-school medicine that I sometimes use, especially if the itching is most prevalent at night, is a drug called doxepin, and that’s been around for a very long time, but it can be extremely sedating and has to be used with caution, especially in patients who are older.

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 Banwell:

What are common side effects of DLBCL treatment approaches? 

Dr. Matasar:

Like anything, the side effects are dependent upon the treatments that we use. So, treatments that use chemotherapy-based approaches will often have the side effects that we associate with chemotherapy. And obviously not all chemotherapies are created equally. But treatments like R-CHOP or R-CHP-pola, or Polarix regimen, these are treatments that use traditional cytotoxic chemotherapy agents and anthracycline based chemotherapy that have well-characterized side effects that are unfortunately unavoidable but often temporary things like hair loss.  

And hair loss is unavoidable with these treatments although temporary.   

The Oncovin or polatuzumab treatments can lead to a problem called neuropathy, which can manifest as numbness or tingling in the fingers or toes or constipation because our intestines have nerves too that are affected by these treatments. Certainly fatigue and lowering of the immune system are common with these and other chemotherapy medicines as well. And your doctors will always talk to you about ways to reduce the risk of infection such as vaccination and such as anti-infective medicines or immune boosting medicines to try to limit the risk of infection while receiving such treatments.
