Katherine:

For newly diagnosed patients, what key advice would you share with them? And are there specific questions they should be asking their doctor about their care plan? 

Dr. Krina Patel:

Yeah. So, I know it’s hardest for newly diagnosed patients. Most people have not even heard what multiple myeloma is. They’re learning how to spell it correctly and making sure it’s not melanoma. And this is a conversation I have with so many of my new patients that I think it’s really hard your visit, and maybe even your second visit, to ask all the right questions. So, really, coming home and every time you’re on a treatment or you’re talking about a treatment and you have a question, write it down because I know it’s really hard when we’re only there for 15, 30 minutes to talk to you.  

For us, we have MyChart, so my patients will send questions as they think of them through that. And I think that’s really important. Sometimes it’s hard to know what questions to ask when you have no idea what’s about to happen, and that’s okay. But I think as you’re going through therapy, really making sure that you ask about alternative therapies that might be available and why someone is picking one versus the other, making sure you know what supportive medications you really need.

And I will say that, with myeloma, a lot of our treatments are patient-friendly but they do cause side effects and infections, so, we have a lot of supportive medications we use; so, again, anti-shingles, potentially if you could get a blood clot, we have you on some type of blood thinner.  

We have people on against steroids because of all of our initial therapies have steroids. We wanna make sure you don’t get ulcers in your stomach, so we have patients on proton pump inhibitors. There’s a lot of things we do to again decrease that toxicity. So, that’s important.  

And then, I think the next part is when you’re on treatment, whatever symptoms you’re having keep a log of that. Some things are, okay, maybe it’s just a little bit here and there, that you’re feeling fatigued but then you’re better. But there are certain things that cause a lot of side effects that my patients sometimes don’t tell me about. So, the steroids can cause major insomnia for some of my patients where they don’t sleep for three days, and that’s not okay. We can decrease those.

So, there are ways to manipulate the treatments as we’re going through to make sure that not only are you having a great response but that you’re not having major side effects that are actually gonna hurt your health down the road. So, really important to discuss those things that you’re having as you’re going through.  

Katherine:

There’s also the importance of a care partner in your life –  

Dr. Krina Patel:

Yes. 

Katherine:

– right?  

Dr. Krina Patel:

I agree. So, I joke with my patients but it’s real; there’s actually a study that shows that men with three and a half women in their lives do much better in healthcare in general than those who don’t. So, I’m like “Go get more women in your life” – 

Katherine:

I love that.  

Dr. Krina Patel:

– or just caregivers in general.  

Men are great caregivers too, but really having someone there that can listen for you and write down those things because it is overwhelming. And when you’re on treatment there are a lot of times when you just can’t pay attention. You can’t focus. You can’t listen to everything. And so, the more people that are there, they’ll pick up other things.

So, a lot my patients will even have their loved ones on their phone with them, even if they can’t be there in person so that they can record. And a lot of my patients will record things and they’ll ask me; so, definitely as whoever you’re talking to if it’s okay to record. But most of us will say “Yes, it’s completely fine” so that you can listen to it again when you go home.

Katherine:

Hello and welcome. I’m your host, Katherine Banwell. As patients collaborate on treatment decisions with their healthcare team, it’s important that they understand all of their options and how these options may be impacted by research developments. That’s why the Patient Empowerment Network created the Evolve Series, to arm you with the latest information and to help you feel empowered and confident during conversations about your care.  

In today’s program, we’re going to hear from an expert in the field about the evolving treatment landscape for myelofibrosis and discuss how you can play an active role in your care.  

Before we get into the discussion, please remember that this program is not a substitute for seeking medical advice. Please refer to your healthcare team about what might be best for you. Well, let’s meet our guest today. Joining us is Dr. Gaby Hobbs. Dr. Hobbs, welcome. Would you please introduce yourself? 

Dr. Hobbs:

Hi, how are you? Thank you so much for inviting me today. My name is Gaby Hobbs. I’m the clinical director of the leukemia service at Mass General Hospital in Boston and the director of the MPN program at MGH as well. I conduct clinical trials as well as see patients with myeloproliferative neoplasms.  

Katherine:

Thank you so much for taking the time to join us today. We really appreciate it.  

Dr. Hobbs:

My pleasure.  

Katherine:

Before we get into our discussion, can you share with the audience how the field of myelofibrosis has changed over the course of your career? 

Dr. Hobbs:

Yeah, so it really has been a very exciting journey. So, when I was in medical school, I think that we basically had just discovered the JAK2 mutation.  

So, in the course of my own training and then my professional career, we’ve gone from myeloproliferative diseases being conditions where we really didn’t necessarily have a reason why people would get these conditions. Now not only do we know about the JAK2 mutation, but we know about many other mutations that patients can have. Then in 2011, the first JAK inhibitor was approved, ruxolitinib (Jakafi), and since then, three additional JAK inhibitors have now been approved, including pacritinib (Vonjo), fedratinib (Inrebic), and most recently, momelotinib (Ojjaara).  

So, the field has definitely advanced concretely in that regard. But we also just have much more information about how to diagnose these conditions and also how to treat them. Outside of the JAK inhibitors, we’re better at recognizing when patients need to go to get a bone marrow transplant. For example, and our outcomes with bone marrow transplantation have improved significantly. We also have many other treatment approaches that wouldn’t have existed before, and we also recognize that patients with MPNs live with a lot of symptoms. So, I think that we’re better at just the doctoring part of taking care of patients with MPN. So, definitely, the field has just really, really changed significantly in the last two decades. 

Katherine:

That sounds like it’s been a rapid change, really. There may be some confusion, Dr. Hobbs, among people wondering what is the difference between primary and secondary myelofibrosis? Could you describe the differences?  

Dr. Hobbs:

Sure. Great question. So, that term, primary and secondary, is actually used in medicine very frequently for the description of many conditions that are not that different. So, primary means a patient has myelofibrosis and did not have any myeloproliferative neoplasm, or MPN, before their diagnosis.  

So, they went to the doctor and the first diagnosis they received was a diagnosis of myelofibrosis. Now sometimes we suspect that a patient may have had another MPN previously, such as essential thrombocythemia or polycythemia vera, but they just weren’t diagnosed.   

What I mean by that is, you know, let’s say you meet a patient and you look through their chart and you see that five years ago or 10 years ago, they had really, really high platelets or very high red blood cell numbers. So, there you could say, well, you know, you were never diagnosed with ET or PV, but maybe you had that. So, you probably have secondary myelofibrosis, but the diagnosis, you know, that you come with to the doctor is myelofibrosis. So, secondary myelofibrosis means that you had an underlying condition before, meaning you were first diagnosed with one condition like PV, polycythemia vera, or ET, and then those conditions turned into myelofibrosis.  

And then we call that secondary myelofibrosis, meaning it is secondary to the primary condition, meaning ET or PV. One area of confusion that I’d like to be able to clarify also related to this is if a person has secondary myelofibrosis, they don’t have two myeloproliferative neoplasms or two conditions. It is one and the same. They just live on a spectrum and over time, they can turn into, one into the other. So, it’s not that you now have two diagnoses, it’s still the same condition, it’s just morphed a little.  

Katherine:

Okay, thank you for that explanation. I’d like to talk about the importance of a patient’s healthcare team. What are the benefits to seeking care with a myelofibrosis specialist, even if it’s just for a second opinion or a consultation? 

Dr. Hobbs:

Great question. I think that one thing that COVID has given us is the ability to have webinars like this, but also that you can seek second opinions more easily with the advent of telehealth.  

So, whereas before I think that getting that second opinion would have been maybe more challenging, perhaps now it’s easier. But to answer your question, these conditions are rare. Myelofibrosis in particular is even more rare than the others.  

The landscape, as I kind of alluded to in our initial question, has changed significantly in the last two decades. So, getting a second opinion, whether that’s, like you said, just for an initial consultation, and then you never see that person again. Or you end up having kind of two doctors, one that treats you for your day-to-day needs and an expert or specialist that sees you occasionally as things may change, which can be very beneficial for a variety of reasons. I think that the first one is to just hear hopefully the same information that your initial doctor gave you, but maybe from a different perspective. I think that’s always helpful when dealing with a new diagnosis.  

Second is, you know, a specialist may have access to clinical trials. Although that may not be the right thing for you when you first meet them, it may be something you would want to consider or may be appropriate for you later down in your treatment. So, being connected to somebody that has access to research is something that, you know, it opens a door.   

Katherine:

We’ve established that research in the field is moving quickly. What are new and emerging therapies that are showing promise?  

Dr. Hobbs:

Yeah, so the list is long and it’s getting longer. So, in addition to the fact that we now have four JAK inhibitors approved, which is worth just remembering that, because not that long ago we only had one, and one of them was just approved less than six months ago.  There are many new agents that are being studied in combination with the JAK inhibitors. This past year at the American Society of Hematology meeting, which is the annual meeting where we go to share our research and learn from our colleagues, there were two Phase III studies that were presented at the same time.  

I can’t remember, or I don’t think, but that has really ever happened before for myelofibrosis. One of them was with an agent called pelabresib, which is a type of molecule called a BET Inhibitor. And the other one was with an agent called navitoclax, which is an agent called a BCLXL-BCL2 inhibitor, which is a molecule that helps cells to undergo apoptosis or programmed cell death.  

So, these molecules were both combined with ruxolitinib. And we saw the results of the Phase III studies for each of these agents, and they were really quite exciting. The punchline for both of these studies is that they demonstrated that when you give two drugs as opposed to just one, the amount of patients that have a significant reduction in their spleen is doubled than when you give ruxolitinib in it by itself. So, for some of our patients that is a really meaningful number. You know, if you’re a patient that suffers from a big spleen, knowing that there’s a possibility of having two drugs that you can take to really shrink that spleen in a significant way, I think is very, very promising. On the symptom front, taking two medicines versus one medicine really didn’t seem to make a huge difference. I think we can analyze this in two different ways.  

We can see the negative or the positive side of this. So, on the negative side, well, it’s too bad that, you know, added medication didn’t help patients feel better. But on the upside, it’s also good that taking two medicines didn’t make people feel worse. Sometimes you can think of, you know, if you’re taking more medication, maybe you will feel worse. So, the jury is kind of still add on the significance of those results. But regardless, without getting into too much detail about these studies, I think it’s really exciting for myelofibrosis patients to know that there are two agents that are in Phase III testing.

That means that the next step is really consideration of FDA approval. So, when medications go through clinical trials, they go through earlier phase studies, Phase I, Phase II, and then finally they get to Phase III. A lot of work and effort has gone into these two compounds to try to get them to FDA approval. So, we’ll wait and see if in the next year or so we have new agents for the treatment of MF.  

In addition to these two, which of course are the most advanced, there really are a variety of other agents that are being tested. Those, for the most part, are still in Phase II testing. And similarly to the ones I mentioned before, most of the compounds, the way that they go into trials is first they start out showing that they’re safe by themselves, and then they get added to a JAK inhibitor.

So, far, because ruxolitinib has been the one that we’ve had around for the longest, most of these studies are being tested in combination with ruxolitinib. But we start to hear rumblings from clinical trials that perhaps some of the newer trials will consider using other JAK inhibitors as combination partners, which is a natural evolution. So, to name a few other agents, we have drugs like selinexor (Xpovio), and navtemadlin we have a PIM kinase inhibitor, a lysyl oxidase inhibitor, an LSD1 inhibitor, the list is long of all these different agents.  

Preliminarily, at least from the data we’ve seen from all of these compounds, I think there’s a lot of room for excitement. We see that combining these drugs together, the new agent plus the ruxolitinib, leads to a significant reduction in the spleen. And in some of these agents, we’re starting to see other endpoints. So, in addition to just looking at can we make patients feel better and can we shrink their spleens?

We’re starting to look at other things such as when we add these medications, do we see a reduction in the scarring or the fibrosis in the bone marrow? Do we see a decrease in the cells that have the mutation? Do we see the patients live longer? All of those things are endpoints in our studies that we really haven’t tested before. So, I think the field really will produce a lot of exciting data in the next couple of years.  

Katherine:

You mentioned clinical trials, and we will talk about those in a few moments, but are there innovations in technology that are accelerating myelofibrosis research?   

Dr. Hobbs:

So, the most obvious way to answer that question is simply that it’s much easier to diagnose myelofibrosis now, thanks to the ability to do genetic testing now much more easily than before. So, I think that previously, you know, getting JAK2 testing or testing for the other mutations was not as simple or would take a long time for the results to come back.  

Now, you know, I see even in the smallest of practices, ordering not just the JAK2 gene, but ordering what many of us do, which is like a panel of genes, where you test for a lot of the genes at the same time, has become almost commonplace. So, that’s really a meaningful advance in that it’s a technology that’s available and it’s no longer as prohibitively expensive as it was before.  

That doesn’t mean that some patients don’t end up getting charged in ways that doesn’t make any sense anymore, but that’s a conversation for another time. But I think just having the ability to make those diagnoses because of how easy it is now to test for these mutations is really very meaningful.

Outside of that, I mean, I would say that along with the improvement in the knowledge of what mutations patients have with myelofibrosis, we definitely have deeper ways of analyzing what genes are being expressed and in what cells they’re being expressed to really understand, you know, when do patients first get those mutations and how do those mutations change over time. So, we’re really diving deep into the actual biology of the bone marrow and there’s some studies that have demonstrated that patients may even have the JAK-2 mutation in utero, which is really, really fascinating. So, definitely a lot more understanding of the actual biology of how these diseases happen.  

Katherine:

Dr. Hobbs, a key part of research moving forward is the clinical trial process. Can you talk about the benefits of patient participation? 

Dr. Hobbs:

Yeah, so I think to answer that question, I should preface that by saying that I conduct clinical trials, and so certainly my answer is going to have that as a bias, so it’s important to know that. And I tell my patients that as well when I’m talking to them about clinical trials. Now, why do I think clinical trials are beneficial? Well, there’s really no way to advance the field without the sacrifice that patients do by allowing us to conduct clinical trials. Without clinical trials, we cannot get drugs approved. Without new drugs, we certainly can’t help our patients anymore with newer therapies. That being said, a clinical trial is something that is not just an experiment. Many times patients will be like, well, I don’t want to be a guinea pig. And I completely respect that.  

So, I think it’s really important to recognize too, that we take conducting clinical trials very, very seriously. The machinery that needs to exist in each hospital to conduct trials includes a ton of people. So, we have a lot of regulatory bodies, both within the hospital and outside of the hospital, to ensure that clinical trials are conducted in an ethical and in a safe way. So, one of the benefits, which you may not consider when you’re contemplating participating in a trial, is that your care team actually becomes much larger. You’re much more closely scrutinized actually, when you’re a member of a trial.

So, whereas before you would have just primarily seen me and my nurse practitioner, when you participate in a clinical trial, all of a sudden you have all these research nurses that are calling you, checking in with you, making sure you’re feeling well, et cetera. So, that’s actually a nice perk to participating in trials. So, an important thing to know with clinical trials is that they may not benefit everybody. 

And that not every clinical trial may be right for you and that there may be times when trials are appropriate and times where trials may not be appropriate. So, it’s not a decision that you make that’s black and white and that’s a decision that you make forever. I think it’s something that you can continue to discuss with your care team as you go through having this disease.  

Katherine:

Let’s move on to treatment. Would you provide an overview of the currently approved therapies for myelofibrosis?  

Dr. Hobbs:

Sure, absolutely. So, I’ve alluded to this a little bit. So, in 2011, we had the first JAK inhibitor approved called ruxolitinib, the brand name is Jakafi. After that, we had the approval of Inrebic or fedratinib and then pacritinib or VONJO, and then most recently momelotinib or Ojjaara. So, we have four different JAK inhibitors that are now approved for myelofibrosis.  

So, who needs to get a JAK inhibitor and how do we choose between the JAK inhibitors? So, the traditional indications for JAK inhibitors are, does a patient have bothersome symptoms from having a big spleen? Does a person have symptoms from their disease? Symptoms can include things like night sweats, itching, unintentional weight loss, brain fog, and fatigue. Fatigue can be challenging because of course many things can cause fatigue. But those are some of the symptoms that can occur with having this disease. So, if a patient has both splenomegaly symptoms or one or the other, they’re eligible for a JAK inhibitor.  

So, just having myelofibrosis doesn’t mean that you need to have a JAK inhibitor right away. Probably the most commonly used JAK inhibitor, and this will be the case probably for a long time, is ruxolitinib.  

The reason for that is that it’s been around for a long time, and it’s a very well-tolerated medication. Patients that have platelets that are very low, meaning platelets that are less than 50, should be considered for pacritinib first, as that’s the indication for that agent. Patients that don’t do that well on ruxolitinib initially, let’s say that the dose gets increased and the spleen and the symptoms are still present, but still have good blood counts, are good candidates for then receiving fedratinib. Fedratinib can also be given upfront. It rarely is given upfront, simply because ruxolitinib has been around for longer and it’s a better-tolerated medication. So, therefore most providers feel more comfortable giving that upfront. I have had some patients that are concerned about the weight gain that is a side effect of ruxolitinib. For those patients, I’ve occasionally considered giving fedratinib first before ruxolitinib. And then lastly, we have momelotinib. It’s approved primarily for patients with myelofibrosis and anemia.  

Now momelotinib is still a JAK inhibitor, so it can still improve symptoms, and it still improves spleen size. So, I struggle with that recommendation of just using it for anemia in patients that don’t have splenomegaly or symptoms.  

But the FDA label was pretty broad, and it’s important to recognize that. So, how is momelotinib being used? It can be used in the upfront setting for patients that have spleen and symptoms, and also anemia, meaning low red blood cell levels. Or,  it can be used for patients that have been treated with a JAK inhibitor first and then develop anemia. So, momelotinib is given to continue to improve the spleen and symptoms, but also help the anemia. So, that’s kind of like an overview of the four JAK inhibitors. Now we have a group of patients that maybe doesn’t have a lot of spleen symptoms or symptoms in general but has issues with having low hemoglobin. So, for those patients, we’ve used a variety of different medications, including medications that are called erythropoietin, which is a hormone that helps to boost the red blood cell levels.  

A medicine that’s similar to testosterone that can also help boost the red blood cell levels called danazol (Danocrine). And then there’s a medication called luspatercept-aamt (Reblozyl) that has been approved for a related condition called myelodysplastic syndrome. And in some clinics, it can be used even though it’s not approved either by itself or in combination with ruxolitinib. And then lastly, patients that have what is called high-risk myelofibrosis, meaning they have some mutations that may indicate that a patient has a higher risk of having complications of their disease, or they have very low blood counts, are usually considered high-risk. Those patients should be recommended and referred to transplantation as soon as they’re identified as having high-risk disease.  

Katherine:

When you say transplantation, you’re referring to stem cell transplant. 

Dr. Hobbs:

Yes, and I’m glad you said it that way actually. So, stem cell transplantation or bone marrow transplantation, same thing, interchangeable, same procedure. You got it.  

Katherine:

Yeah. So, where do clinical trials fit into a treatment plan? 

Dr. Hobbs:

So, it really depends on what is available at the site where you’re seeking care. Clinical trials come in a variety of different flavors. So, there may be a clinical trial for patients that are newly diagnosed, that are about to start a JAK inhibitor, for example.  

So, if you’re a patient that’s considering a JAK inhibitor to treat your spleen symptoms or your systemic symptoms, and there happens to be a clinical trial for adding on another medication, like the first JAK inhibitor you receive, well, that’s a great place to consider a clinical trial.  

There may also be clinical trials in later lines. Let’s say you were treated only with a JAK inhibitor first, but the study that’s available at your center is adding another medication to the JAK inhibitor if the JAK inhibitor by itself didn’t quite do the trick. 

There’s also other studies, for example, at the time of transplantation, for example, using the JAK inhibitors during transplant. So, really the clinical trials can be relevant at any time during treatment. In addition to clinical trials, testing new medications, there’s also other ways to participate in research throughout your time as a patient with your care team, which may include things like, for example, consenting to participate in a tissue bank.  

You donate a sample of your blood or bone marrow that is then later on used for research. Or we may have studies investigating the symptoms a patient has throughout their disease or their experience living with their disease. So, there’s many different ways of participating in research and clinical trials, even if those don’t necessarily include trying a new medication.  

Katherine:

What questions should patients be asking if they’re interested in learning more about clinical trials?  

Dr. Hobbs:

Yeah, great question. So, the first is understanding, you know, what is the medication that you will be receiving? Are you going to be receiving a placebo? Is that an option? This means a sugar pill. That’s a common question that I get. How do you get assigned to different groups? So, in one trial, there may be a group that gets one dose, another group that gets another dose, et cetera. So, it’d be important to know how are you going to get assigned and what are the options potentially for you before you sign up. After that, it’s important to know what phase the study is in.

So, is this a first-in-human study where your doctor may not be able to tell you a whole lot about what’s expected in terms of side effects or safety or toxicity? Or is this a Phase III study where maybe the trial has been open for many years and there’s been many patients that have been enrolled in it already? Or maybe this is a drug that’s already been approved for another condition and we’re borrowing it for myelofibrosis, for example, and then your care team can tell you lots of information about the safety and toxicities, etc.  

So, having a sense of where the drug is in its development, I think can be very helpful. Then there are some practical things that we sometimes do not spend enough time talking about.  

So, I’m glad to have the space to talk about that here. Participating in a clinical trial takes time. And it’ll take more time as a patient to participate in a clinical trial than to receive regular care. You may have to go to the hospital where you’re being treated more frequently. If you’re somebody that receives virtual care where some of your visits are telehealth and some of them are in person, you need to be aware that you may have more visits that are in person because the clinical trial procedure requires that certain labs or tests be done in the facility, not anywhere else. Clinical trials by definition, unfortunately, sometimes have to be very inflexible in order to ensure that we collect data in a uniform way.  

So, just being aware that it may take more time to participate is important. And along those lines, asking if the clinical trial will reimburse you for some of that time. So, for example, if you need to park in the expensive hospital parking more frequently, some trials will actually reimburse you for that. Or they may offer a hotel reimbursement if you need to travel from far away and spend a night there. So, don’t be afraid to ask those things because many times that’s built into the clinical trial.

So, that’s an important thing just practically to know. So, asking for a study calendar so you get a sense of how frequently you’ll need to be going to the doctor is really important. Also, then realizing that potentially you may have to go to see the doctor or the care team more frequently initially, but then after the first couple of months, if everything is going well, you’ll likely have the flexibility to go less often. So, all those questions are important to have in mind.  

Katherine:

That’s great information, thanks, Dr. Hobbs. When considering therapy, how do you approach a treatment plan for someone diagnosed with myelofibrosis?  

Dr. Hobbs:

Great question. So, when approaching how I care for a patient with myelofibrosis, I take several things into account. The first thing is, who is this patient? What other medical conditions do they have? How impacted are they by their myelofibrosis? Then what I like to do is to plug in the numbers of the patient, their blood work, their mutations, etcetera, into one of the many risk calculators that we have to determine what the risk of their myelofibrosis is. 

If a patient is considered high-risk, I will generally consider transplantation or discuss a referral to a bone marrow transplantation in one of our first visits, if not the first visit. After that, I need to determine whether or not the patient has symptoms from their disease, and if so, if they should receive a JAK inhibitor. Then I’ll look through their blood work, what their symptoms are to decide which JAK inhibitor to use first.  

If really the spleen and symptoms aren’t the primary issue, if it’s more related to low blood counts, then we can think about treatments directed at improving the hemoglobin, for example. There may be a group of patients that don’t actually require any treatment when I first meet them. So, just providing them with education, what to expect. Then discussing more of the psychological impact of living with a condition and approaches to handle that, maybe more the focus of my care.

And in general, for most of my patients, we also talk about the rest of the care. So, not just what the blood work is and what medicine I’m going to start them on, but also other things that they can do to take care of themselves, including making sure that they are actively monitored by their primary care doctor or by other specialists if that’s still appropriate. You know, one of the things we don’t discuss that frequently in myelofibrosis, we discuss that more often in essential thrombocythemia or polycythemia vera is a risk of blood clots.  

But the truth is that myelofibrosis patients can also have risks of blood clots. So, therefore, making sure that patients with MF that may have issues like hypertension, diabetes, high cholesterol, etc., get those well-managed is also really important to prevent them from having blood clots. So, lifestyle management is also an important part of the care of a patient with myelofibrosis. 

Katherine:

That’s all great advice. A note to our viewers, PEN has also created downloadable office visit planners to help you organize your thoughts and communicate effectively with your healthcare team. You can find those in the MPN Toolkit at powerfulpatients.org or by scanning the QR code on your screen.  

Well, it’s been a lot of great information, Dr. Hobbs, and I’d like to close with your thoughts on the future of myelofibrosis care. Where are we headed and what would you like to leave our audience with?   

Dr. Hobbs:

Well, the first thing I wanted to say is just kind of piggyback with what you said about the visit planner. I love that. I think that many times patients come to a visit and they’re like, oh, I had this question that I wanted to ask you and now I can’t remember what it was. And especially if you’re seeing a doctor every six months or something like that, making sure that you come to that visit prepared with lots of questions is an excellent way to make the most use out of your visit with your provider. So, I definitely encourage you to do that. In terms of what to leave patients with, so going back to what we were discussing initially, the list of new agents that are being investigated for myelofibrosis is long and longer by the day. So, as a myelofibrosis doctor, I really feel very optimistic that in  the next year and hopefully in the next couple of years, we’re going to have a variety of new treatment options that are going to really help our patients to live not just longer with their myelofibrosis, but truly to live much better with their myelofibrosis.  

So,  continue to get informed by watching webinars such as this one and reading reliable sources of information on different patient advocacy organizations because there’s really a lot of changes that are happening. So, I definitely think it’s a time to feel hopeful about the future of  myelofibrosis.

Brian: 

Hi, I’m Brian. Nice to meet you! I’ve been living with a condition called myelofibrosis for many years. While there have certainly been ups and downs, I’ve been able to navigate care for my condition and to live a full life.  

So how have I been able to do that? First and foremost, I have a great relationship with my care team, whom I communicate with regularly. Meet, Dr. Liu – my doctor. 

Dr. Liu: 

Hi! I’m Dr. Liu, and I’m a hematologist and a specialist in myeloproliferative neoplasms or MPNs. The three types of MPNs are essential thrombocythemia, or ET,  polycythemia vera or PV, and myelofibrosis, or MF.  This group of blood cancers is characterized by the bone marrow overproducing a certain type of cell.  

Maintaining a good relationship with your healthcare team, coupled with finding a treatment approach that works for you, can help you live a full life and to thrive with an MPN. 

Brian: 

Exactly, Dr. Liu. Over the years, I’ve experienced periodic issues with my condition. I’ve had symptoms and treatment side effects that have been bothersome and interfered with my life. But, communication with my team has been essential to feeling well.  

Dr. Liu: 

That’s right, Brian. When symptoms or treatment side effects are bothering you, it’s important to let your healthcare provide know how you are feeling. 

Brian: 

For example, recently I felt tired beyond general sleepiness. And when I shared this with Dr. Liu, we discussed potential causes of the fatigue, and we talked in-depth about my options to manage it, including changing therapy and some simple changes to my diet and lifestyle.1 Over time, my energy levels improved, but having the open dialogue with Dr. Liu was essential to tackling this symptom head-on. 

Dr. Liu: 

That’s a great example. When I first hear from a patient that they are having an issue, we go through several steps to find a solution.2  

We start by ensuring that the disease is well-controlled, so we check blood counts. Next, we try to determine if it is a symptom of the MPN or a side effect of the treatment. Once we’ve done those steps, we come up with potential solutions which may include, but are not limited to: 

  • A dose reduction or a treatment holiday. 
  • Changing therapy to find something that is more well-tolerated. 

Other considerations are dependent upon the specific symptoms and side effects but may include: 

  • Supportive care options, including diet and exercise. 
  • A visit to your primary care doctor to see if there is something else going on physically. 

Brian: 

That’s good to know, Dr. Liu. Something you brought up with me, which I feel is important to mention, is mental health. Often, emotional symptoms can take a toll on the body, causing fatigue or other issues. 

Dr. Liu: 

Great point, Brian. Seeking care for your mental health is crucial, particularly if you are in active treatment. 

Brian: 

Of course, we know that the symptoms and treatment side effects for MPNs can vary widely, so what advice do you have for patients who may be afraid to speak up? 

Dr. Liu: 

The most important thing to remember is that we have options to help you, no matter what you are going through. It’s your body and if you don’t let your provider know what you’re going through, they can’t help you. 

Brian: 

So true. It’s also a good idea to bring a care partner along to appointments, sometimes a spouse or friend can you help you communicate what’s going on. 

Dr. Liu: 

That’s great advice, Brian. Bringing someone along to take notes is a great idea. Also, be sure to write down any questions or concerns you have in advance to make the most of your appointment. 

Brian: 

OK, Dr. Liu, let’s recap your advice for MPN symptom management: 

Dr. Liu: 

Good idea! First, remember that everyone’s MPN is different, so managing symptoms and side effects can be tricky. Communicating with your healthcare team is critical to your overall care – report any and all concerns to your team immediately. 

And, do your part. Make sure you see your primary care physician regularly and do your best to maintain a healthy lifestyle. 

Brian 

And, most importantly, remember you are at the center of your care. Never hesitate to share your opinion and to advocate for yourself.

Katherine Banwell:

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.  

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.

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.  

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:

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

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

Dr. Pemmaraju:

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

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

Katherine Banwell:

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

Dr. Pemmaraju:

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

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

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

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

Katherine Banwell:

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

Dr. Pemmaraju:

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

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

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

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

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

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

Katherine Banwell:

What about interferon? What are some common side effects?  

Dr. Pemmaraju:

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

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

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

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

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

Katherine Banwell:

What about hydrea 

Dr. Pemmaraju:

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

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

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

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

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

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

Katherine Banwell:

With all the testing, yeah.  

Dr. Pemmaraju:

Exactly, right.  

Katherine Banwell:

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

Dr. Pemmaraju:

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

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

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

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

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

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

Katherine Banwell:

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

Dr. Pemmaraju:

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

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

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

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

Katherine Banwell:

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

Dr. Pemmaraju:

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

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

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

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

Katherine Banwell:

What about essential thrombocythemia or ET? 

Dr. Pemmaraju:

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

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

Katherine Banwell:

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

Dr. Pemmaraju:

Right. 

Katherine Banwell:

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

Dr. Pemmaraju:

Let’s do that.  

Katherine Banwell:

How do you manage that?  

Dr. Pemmaraju:

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

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

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

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

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

Katherine Banwell:

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

Dr. Pemmaraju:

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

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

Katherine Banwell:

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

Dr. Pemmaraju:

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

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

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

Katherine Banwell:

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

Dr. Pemmaraju:

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

Katherine Banwell:

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

Dr. Pemmaraju:

Great. 

Katherine Banwell:

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

Dr. Pemmaraju:

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

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

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

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

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

Katherine Banwell:

Oh. 

Dr. Pemmaraju:

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

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

Katherine Banwell:

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

Dr. Pemmaraju:

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

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

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

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

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

Katherine Banwell:

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

Dr. Pemmaraju:

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

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

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

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

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

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

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

Katherine Banwell:

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

Dr. Pemmaraju:

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

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

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

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

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

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

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

Katherine Banwell:

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

Dr. Pemmaraju:

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

Katherine Banwell:

Yeah, thank you. And thank you to all of our partners. To learn more about MPNs and to access tools to help you become a proactive patient, visit powerfulpatients.org. I’m Katherine Banwell. Thanks for joining us today.

Lisa Hatfield:

Dr. Amanam, can you speak to any exciting new developments in MPN care or trials that you see moving forward with great progress?

Dr. Indoroenyi Amanam:

Yeah. I think for MPNs and namely really the classic BCR-able or Philadelphia chromosome-negative MPNs, which include essential thrombocythemia, polycythemia vera, and myelofibrosis. I think we have a lot of exciting therapies that are going to be possibly FDA-approved in the next couple of years. So currently, for essential thrombocythemia, really the dogma therapy is related to keeping the counts under control and giving a therapy to reduce the risk of having a blood clot or stroke. We actually are in a space where we have therapies that are going to be targeting the underlying clone or basically the cells that are driving the proliferation of these platelets that lead to high platelet counts. And so I think that’s exciting.

So we do know that, in MPN there is an overexpression of Bcl-xL, and there’s a drug that targets Bcl-xL. And we’ve seen really great responses in essential thrombocythemia. And as a segue, this drug also targets the same cells and polycythemia vera and myelofibrosis, and we’ve seen really great responses in those patients. We also have had difficulty in managing patients who have myelofibrosis, but have very low counts. And typically the FDA-approved drugs that we’ve been using actually make the counts worse.

And so there are multiple drugs that are in the pipeline that are helping patients with low blood counts. And what they do is they help increase your red blood cells and reduce your requirements for red blood cell transfusions.

And one of the drugs helps stimulate erythropoiesis, and it’s an injection. And we’ve seen really good results in reducing the risk of…or reducing the amount of transfusions that patients receive. And then another one of these drugs targets ACVR1, which we understand that in myelofibrosis, you have overproduction of hepcidin, which leads to worsening anemia. And so by targeting ACVR1, it helps control this hepcidin. And by doing that these patients have improved red blood cell counts. And so that’s another drug that likely will be coming…that will be FDA-approved very soon, and I think will help patients in this space.

We also are interested in immunotherapy. And I think in other cancers, immunotherapy has been very successful in eradicating those cancer cells and curing some patients. And so there are clinical trials looking at a vaccine which targets certain mutations that are relevant to MPN patients. And also we are interested in actually using other types of immunotherapy namely, CAR T, which really helps connect your own immune cells to these cancer cells to help clear them out. And so I think over in the next five to 10 years, there’re going to be a lot of drugs and a lot of therapies that are going to really help patients who have MPNs.

Lisa Hatfield:

So this patient is asking, “For patients who may be eligible for BTK inhibitors, are there specific comorbidities that might contribute to adverse side effects?”

Dr. Ryan Jacobs:

Yeah, so we screen…all BTK inhibitors have some cardiac toxicity. They have been shown with the second-generation BTK inhibitors to have less cardiac toxicity than ibrutinib, specifically atrial fibrillation. So if you have atrial fibrillation, maybe that’s a reason why you might go on venetoclax first as opposed to a BTK inhibitor. But it’s not a contraindication to getting a BTK inhibitor if the atrial fibrillation is under good control. Other cardiac risk factors would include difficult to control hypertension at baseline, or heart failure. These are all things that might make us think twice about using a BTK inhibitor as our first therapy, because venetoclax has no cardiac toxicities.

The other thing to consider is BTK inhibitors all to a degree have, and I describe it to patients, like an aspirin-like effect on the platelets. They do interfere with the platelet binding, which so universally, patients will know to varying levels some easier bruising. And if patients are on, because of say, they’ve had a heart attack in the past and they’re on aspirin at baseline, or what would even be more concerning if they were on a drug like Plavix because they’ve had a stent placed, that would be something that would really concern me and would definitely push me more towards venetoclax (Venclexta), that again, doesn’t have those anti-platelet interactions. Also, patients who are on blood thinners because of a history of blood clot or atrial fibrillation, there is the potential increased risk for bleeding and bruising there as well.  None of these are absolute contraindications, they’re just all what goes into the blender, if you will, of putting lots of information in and coming up with the best treatment decision as personalized for the CLL patient. We’re blessed to have multiple options, but it does make it more of a challenge to find the “best” option.

Transcript:

Katherine Banwell:

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

Dr. Raajit Rampal:

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

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

Katherine Banwell:

How often should lab tests of blood work be done? 

Dr. Raajit Rampal:

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

Katherine Banwell:

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

Dr. Raajit Rampal:

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

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

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

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

Katherine Banwell:

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

Dr. Raajit Rampal:

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

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

Katherine Banwell:

What should patients be asking once they have the results? 

Dr. Raajit Rampal:

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

Katherine Banwell:

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

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

Dr. Raajit Rampal:

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

Katherine Banwell:

Thank you so much for being with us today. 

Dr. Raajit Rampal:

My pleasure.  

Katherine Banwell:

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

Dr. Raajit Rampal:

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

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

Katherine Banwell:

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

Dr. Raajit Rampal:

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

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

Katherine Banwell:

What are treatment goals and how are they determined?  

Dr. Raajit Rampal:

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

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

Katherine Banwell:

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

Dr. Raajit Rampal:

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

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

Katherine Banwell:

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

Dr. Raajit Rampal:

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

So, it depends on the individual. 

Katherine Banwell:

Dr. Raajit Rampal:

 question. The genetics are becoming increasingly important in our treatment decisions. So, let’s take a simple example, which is patients with ET. Calreticulin and JAK2 and MPL are the three most common mutations that we see. But they have very different invocation. So, somebody could have a calreticulin-mutated ET and based on them having that calreticulin mutation and no other factors like no history of clotting, that patient may never need to go on a medication aside from aspirin.

Katherine Banwell:

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

Dr. Raajit Rampal:

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

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

Katherine Banwell:

What should patients be asking once they have the results? 

Dr. Raajit Rampal:

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

Katherine Banwell:

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

Dr. Raajit Rampal:

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

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

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

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

Katherine Banwell:

There’s also transplants available, right? 

Dr. Raajit Rampal:

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

Katherine Banwell:

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

Dr. Raajit Rampal:

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

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

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

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

Katherine Banwell:

Finally, how is essential thrombocythemia treated? 

Dr. Raajit Rampal:

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

Katherine Banwell:

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

Dr. Raajit Rampal:

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

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

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

Katherine Banwell:

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

Dr. Raajit Rampal:

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

Katherine Banwell:

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

Dr. Raajit Rampal:

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

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

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

Katherine Banwell:

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

Dr. Raajit Rampal:

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

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

Katherine Banwell:

Well, is there any way to prevent progression?  

Dr. Raajit Rampal:

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

Katherine Banwell:

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

And what is the best treatment for it? 

Dr. Raajit Rampal:

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

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

Katherine Banwell:

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

Dr. Raajit Rampal:

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

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

 Katherine Banwell:

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

Dr. Raajit Rampal:

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

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

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

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

Katherine Banwell: 

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

Dr. Raajit Rampal:

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

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

Katherine Banwell:

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

Dr. Raajit Rampal:

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

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

Katherine Banwell:

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

Dr. Raajit Rampal:

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

Katherine Banwell:

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

Dr. Raajit Rampal:

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

Katherine Banwell:

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

Dr. Raajit Rampal:

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

Katherine Banwell:

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

Dr. Raajit Rampal:

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

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

Katherine Banwell:

What should patients be asking once they have the results? 

Dr. Raajit Rampal:

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

Katherine Banwell:

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

Dr. Raajit Rampal:

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

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

Katherine Banwell:

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

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

Dr. Raajit Rampal:

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

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

Katherine Banwell:

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

Dr. Raajit Rampal:

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

Katherine Banwell:

What about cost? 

Dr. Raajit Rampal:

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

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

Katherine Banwell:

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

Dr. Raajit Rampal:

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

Katherine Banwell:

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

Dr. Raajit Rampal:

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

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

Katherine Banwell:

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

Dr. Raajit Rampal:

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

Katherine Banwell:

Dr. Rampal, thank you so much for joining us.

Dr. Palmer:

So I think one of the key…so when we look at treating different myeloproliferative neoplasms, you have to take what’s your goal of therapy. So for the ones like essential thrombocythemia, where you have too many platelets, or polycythemia vera, where there’s too many red cells. A lot of times what you’re doing there is you’re just saying, “Well, how can I predict whether you’re going to have a blood clot or something?” Because people can live, these can be fairly chronic diseases that with appropriate therapy, people can live a long time.

So a lot of that’s risk mitigation. Where I think a lot of the personalized aspect of it is coming in is probably in myelofibrosis, which is a disease where I view it as too much inflammation, scar tissue develops in the bone marrow, people could get a large spleen, high white blood cell count. A number of different manifestations. And in that, we’re learning more and more that in addition to the three driver mutations, the JAK2, the MPL, and the calreticulin, there’s probably a whole other group of mutations that can really be used to help us predict and try to take a look into the future to help guide them. And what is the timing for transplant? Should we be more aggressive as we’re getting more and more agents being evaluated and hopefully approved in the treatment of myeloproliferative diseases? Who are the people who should utilize these agents?

Because again, you don’t want to overtreat. And so I think that being able to hone in on these different mutations to be able to help us predict what we think will happen and maybe different treatment options that we would have, that’s going to be important. Now, one of the things that’s really exciting is that some of these companies that actually do this deep sequence, like looking at multiple, multiple genes, actually have mechanisms by which they will send somebody to a person’s house and then draw the blood and take it over and run it. And so I’ve actually had that done before, where somebody I saw via telemedicine, and we really wanted to get that information so I could appropriately advise on what I anticipated was going to happen in the course of the disease.

And we were able to actually get that information through using home care, saying, “I want this order to be done. The home care people went out, drew the blood, sent it to where it needed to go in the right format, and I was able to get that information.” So I think that telemedicine allows them access to people who understand how to interpret that information. But I think we have to give a lot of props to a lot of these companies that are really getting innovative in how they’re capturing the data, saying, no, you know what? You don’t need to have this done in Scottsdale, Arizona or Phoenix, Arizona. You can have this done in your own home and wherever your home happens to be.

So I think that that type of thing is really changing some of how we can utilize that data that’s very personalized, but be able to use it in a telemedicine format where we don’t need people to physically come here to get their blood taken. Now, I do want to add the caveat. There are a number of different institutions have enormous amounts of lab work that’s looking at things above and beyond the approved tests that have been validated and everything. And that would be a lot harder to get. There still are ways of doing that, but I think that we have to acknowledge that there is something that we do lose by doing that. Although I can get a lot of information, be able to provide a lot of input to a patient. It still doesn’t address the fact that by physically being there, sometimes you can get samples that you can biobank and you can send to somebody’s lab. And then these are the people who are discovering the new things that really that’s how we learned what we know so far. Is because somebody went and looked at these genes and more and more and more of this is going on. So I want to temper this with saying not everything can be done by a telemedicine.

That we have to be thoughtful about our approaches and really utilize combining in-person visits along with telemedicine to really do care. And to give an example, what I do for patients is if I follow them by a telemedicine only, I won’t actually be a prescribing doctor. I won’t be a primary provider. I have to at least see them once a year if I’m going to give medicines or do things like that. So I think that there’s a hybrid model that’s going to be really important to do as well for patients who are able to do that.

Lisa Hatfield:

Thanks for that.

Dr. Palmer:

If that makes…yeah.

Lisa Hatfield:

It does make sense. And I just had a quick question too. So if I’m coming in or I’m going to see my…I’m a newly diagnosed MPN patient going into my local oncologist. I’m watching this webinar and I hear, “Oh, if somebody came to my home. I could maybe do telemedicine, or I can have somebody come to my home and take my blood and look at these genetic mutations. My local oncologist doesn’t know exactly how to go about doing that.” Would that be the point where they might try to contact a specialist or go through the consult center through Mayo Clinic or somewhere to say, “Oh, I need a specialist to help me access this type of testing?”

Dr. Palmer:

So I have to be very honest. I just learned about this type of testing in the last year or so. And so it’s something that I’ve started to be able to utilize. With myeloproliferative diseases, I think, and very honestly, and there’s a number of us specialists around the country, I think everyone seeing one at least once in terms of just saying, hey, what’s our plan of care going to be? Are we looking at all the angles of it is a really important thing to do. And I think there’s a number of excellent physicians out there in different parts of the country that some of whom are using telemedicine, some I’m not sure that they are. But I think that getting that specialized opinion is extremely important. I think then in terms of managing care, there’s multiple… There’s multiple ways that can be configured that will help take care of the patient depending on their individual needs and their ability to travel and everything.

How Can Patients Navigate Care and Thrive with an MPN?


Transcript:

Brian: 

Hi, I’m Brian. Nice to meet you! Many years ago, I was diagnosed with a condition called myelofibrosis. At first, it was a scary to learn that I had cancer, but once I found the right treatment option for me, I’ve been living a full life.  

Meet, Dr. Liu – my doctor. 

Dr. Liu: 

Hi! I’m Dr. Liu, and I’m a hematologist specializing in the care of people with myeloproliferative neoplasms or MPNs.   

MPNs are a group of blood cancers that are characterized by the bone marrow overproducing a certain type of cell. The three types of MPNs are essential thrombocythemia, or ET,  polycythemia vera or PV, and myelofibrosis, or MF. 

As Brian mentioned, with the right treatment, it is possible to live a full life and to thrive with an MPN. 

Brian: 

It’s so true. Navigating my care has been much easier because I partner with my healthcare team – participating in decisions makes me feel like an important member of the team. 

Dr. Liu: 

That’s right, Brian. When considering treatment, it’s important to weigh all of your options.  

While your healthcare team is the expert when it comes to the clinical side of your disease, you as the patient, are the expert on how treatment will impact YOU and your lifestyle.  

Brian: 

And as someone who knows my needs well, my wife is another key member of my team.  She comes with me to appointments and takes notes during visits, and when it is time to make decisions about my care, we both feel well-informed about the options. 

So, Dr. Liu – what factors should be considered when choosing an MPN treatment?  

Dr. Liu: 

Well, it’s important to note that everyone’s MPN is different so what may work for one person, may not work for another. In general, we consider certain factors,1 such as: 

  • The type of MPN, whether it is ET, PV, or MF. 
  • The patient’s age and overall health. 
  • Test results, including blood work or any genetic testing that has taken place. 
  • The symptom burden, which basically means how much the disease symptoms are interfering with a patient’s quality of life. 
  • Any pre-existing health issues. 
  • Finally, and most importantly, the patient’s preference.  

Brian: 

And I like to make informed decisions. So, when considering therapy, I also did some research on my own, and then discussed the information with my healthcare team. It helped my wife and me understand what we’d learned, and confirmed our decision. 

Dr. Liu, what sort of questions should patients ask their doctor when considering a treatment plan? 

Dr. Liu: 

Great question. When choosing therapy, patients should ask: 

  • How is the treatment administered, and how often will I need treatment? 
  • What are the potential side effects of the treatment? 
  • How will the effectiveness of the treatment be monitored? 
  • And, what are options if this treatment doesn’t work for me? 

Brian: 

That’s great advice. Once you’ve begun treatment, it’s important to continue to share how you are feeling with your healthcare team – be sure to mention any side effects or symptoms you may be having with your team. 

Dr. Liu: 

That’s right, Brian. If you speak up about what’s bothering you, we can usually find a way to manage the issue. 

It’s also important point to tell your doctor if you’ve missed a dose of your medication. Many of the newer MPN therapies are self-administered, and it’s important to let us know so we can adjust the plan if necessary. 

So, what steps should you take to thrive in your life with an MPN? 

Brian: 

  • First, understand and participate in treatment decisions. Be sure to share your personal preferences. 
  • Then, communicate regularly with your healthcare team – don’t wait to share information only when you have an appointment.  
  • And, utilize your whole team – nurses, nurse practitioners, and others, are all there to help you. 
  • Use your patient portal. You can view lab work and test results, or even use the messaging feature to communicate with your team. 
  • Bring a friend or loved one to appointments and always write down any questions or concerns in advance.  

Dr. Liu: 

And, most importantly, remember you are at the center of your care. Advocate for yourself!

Transcript:

Katherine Banwell:

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

Dr. Scandura:

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

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

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

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

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

Katherine:

Right. 

Dr. Scandura:

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

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

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

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

Katherine:

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

Dr. Scandura:

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

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

Katherine:

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

Dr. Scandura:

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

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

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

Katherine:

When is a bone marrow biopsy necessary? 

Dr. Scandura:

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

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

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