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:

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:

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:

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:

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.

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.

Katherine:

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

Dr. Hobbs:

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

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

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

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

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

Katherine:

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

Dr. Hobbs:

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

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

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

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

Katherine:

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

Dr. Hobbs:

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

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

Katherine:

So, what should be considered when deciding whether to join a trial? 

Dr. Hobbs:

What a great question. Many things need to be considered when joining a trial. And I think some patients are really eager to join a trial, and they just need to be aware that they may be either too healthy, or they may have other things going on that may not make them eligible.  

And that’s okay. There are actually many ways of participating in research, even if it’s not a clinical trial that requires a medicine. For example, we often can send patients to what’s called a tissue bank where they have patients just give a sample of blood.  

So, patients can participate in research in many different ways. When considering whether or not a patient should enroll in an actual clinical trial with a new medicine, I think it’s really important for the patients to be informed and to not be afraid to ask questions. First, what is a clinical trial? Second, what will this trial involve? Is this a drug that has never been given to people before, or is this a drug that has already undergone many different clinical trials? And this trial that’s being offered is a Phase III trial where the purpose of the study is to get the drug to be approved.  

So, I think learning about the risk of the study, how it’s been utilized, and also the other more practical things. What is the time commitment of this clinical trial? How often are you going to have to be going to the office because of the clinical trial? Because there’s certainly a big investment in the part of the patients in terms of their time. Participating in a clinical trial most of the time requires more time than not participating in a clinical trial. That’s not always the case. There are some studies that definitely don’t require that many visits.  

But most clinical trials will require at least something extra from the patient. And I think it’s really important to ask about that, to read the consent that’s given to the patients. Oftentimes these consents are very long.  

And so, they can be overwhelming. I personally find them overwhelming. And I review a lot of those consents. And so, I think taking a minute to really ask those questions, speaking to the research staff, and getting the clarification on that is really important.  

Like you said, it is impossible to approve new therapies and improve the care that we offer our patients without patients participating in the clinical trial. But that doesn’t mean that absolutely every single patient needs to participate in a clinical trial if it just doesn’t make sense for them.

Transcript:

Katherine:

I’d like to start by discussing your role as an MPN researcher. You’re on the front lines for advancements in the field. What led you to there, and why is it so important to you?  

Dr. Hobbs:

Many things in my life led me to becoming an MPN clinician. First, I wanted to be a clinical investigator since I was very little, and I read a Louis Pasteur book about – you know. And I was fascinated by the fact that you could be both a scientist and a clinician. And after that, I had phenomenal teachers and mentors. And I was really always drawn to patients with hematologic malignancies. I thought that that interaction was very intense and intimate.  

And I was honored to be a part of that interaction. And then from a research perspective and from a scientific perspective, I very clearly remember seeing when the first targeted therapy, Imatinib, was approved when I was an undergrad. And I just thought that was the most fascinating thing. And so, I’ve basically continued to feel that way as I’ve gone through my training, and I’m thrilled to be able to have actually become an MPN clinician so many years later.   

Katherine:

With the American Society of Hematology or ASH meeting taking place this month, it demonstrates how researchers work together around the world to advance care.  

Can you share with the audience how this collaboration works?  

Dr. Hobbs:

Yeah. So, the American Society of Hematology meeting – or the ASH meeting – is really one of my favorite events of the year.  

And it really highlights what you said. It is such a positive environment, and it’s so exciting to use that opportunity to talk to my collaborators from across the globe. And I really think that that’s where the scientific community shines because really all of us are actually trying to figure out how to work together and overcome sometimes a lot of obstacles – bureaucratic obstacles, regulatory obstacles – to make sure that we can share data, do it the right way. But really we always have one thing in mind.  

And that is to be able to advance the care that we give our patients. And so, that collaboration and really that collaborative environment is always very positive. And I always come back home very energized from that. And then just seeing all my colleagues presenting all the wonderful things that they are working on and getting updates on their research is just an exciting environment.   

 Katherine:

In your view, why is it essential to present and share data at these larger conferences like ASH? 

Dr. Hobbs:

So, for many different reasons. I mean, there are many different ways of presenting data that can be done through just publishing a paper. But the nice thing about conferences – and especially large conferences – is that you really get an opportunity to present work in progress. And some of these research projects may not end up turning into bigger projects or they may not become bigger trials. But all of them have at least an opportunity to learn something from them, whether or not they worked or they didn’t work.   

Oftentimes when things are published in journals, especially the high-impact journals, we are seeing trials that had positive results. But sometimes we don’t see those smaller trials that never went anywhere. And so, having a forum when we can discuss work that’s ongoing, discuss about projects that are maybe having issues, all those things actually really help us to change our research questions or develop new research questions based on what’s working and also really what’s not working. And so, having this large forum to present all of that data, I think, is really, really important to helping us design future clinical trials and projects.

Dr. Fleischman:

My name is Angela Fleischman. I’m what’s called a physician scientist, meaning, I do research as well as see patients, and my focus for my entire career thus far has been on myeloproliferative neoplasms, specifically their role of inflammation in MPN. And I am at the University of California, Irvine in Southern California. So, nice to be here today. 

Katherine:

Well, thank you so much for joining us and taking the time. Let’s talk about the latest developments in the field. What MPN clinical trials are you excited about right now? 

Dr. Fleischman:

So, I would say, there’s a lot of new clinical trials in the field for myelofibrosis, which is the most severe form of myeloproliferative neoplasm. 

There tend to be more clinical trials because that’s a patient population in – I don’t want to say in more need, but they do have more need in terms of necessitating better treatments. 

Drugs that are quite far along in clinical trials – and in order for a drug to make it to market, one needs to go through multiple clinical trials to demonstrate the safety, as well as efficacy. Things like a BET inhibitor are very, very promising in moving forward in clinical trials. Other medications for other diseases, such as polycythemia vera, not anymore in clinical trials, but excitingly, newly FDA-approved, was ropeginterferon (Besremi) for polycythemia vera. 

So, that’s a real exciting development for polycythemia vera patients. 

And now, we have – outside of the context of clinical trials, because I want to talk about what’s actually available to patients now, we now have three JAK inhibitors available for myelofibrosis patients. And really, since 2011, we had only had one, and then, more recently, a second JAK inhibitor, but now, we have three. So, now we’re moving into an era where we can tailor a specific JAK inhibitor for a specific myelofibrosis patient, depending on what their particular needs are. So, I think that that’s very promising. And then, there are lots of clinical trials combining JAK inhibitors with new drugs. 

Katherine:

What do you want to leave MPN patients with, relating to clinical trial participation? 

Dr. Fleischman:

I would say that MPN patients today are the key to our future treatments. 

Without participation in clinical trials today, there’s going to be no new drugs for myeloproliferative neoplasms. They’re just not going to appear. We need to test them in patients before them actually coming to market, and before really knowing whether they work or not. So, I would say that the MPN patients today are the key to the future of MPN treatments.

Katherine:

Hello and welcome. I’m Katherine Banwell, your host for today’s program. Today we’re going to discuss the advancements in MPN research through clinical trials. Before we get into the discussion, please remember that this program is not a substitute for seeking medical advice. Please refer to your healthcare team about what might be best for you. Well, let’s meet our guest today. Joining me is Dr. Gabby Hobbs. Dr. Hobbs, welcome. Would you please introduce yourself? 

Dr. Hobbs:

Hi, how are you? Thank you so much for having me. My name is Gabby Hobbs. I’m the clinical director of the Adult Leukemia Service at the Massachusetts General Hospital in Boston. And I dedicate my clinical time and research efforts to the care of patients with Myeloproliferative Neoplasms.  

Katherine:

Thank you so much for taking the time to join us today.  

Dr. Hobbs:

Thank you.  

Katherine:

I’d like to start by discussing your role as an MPN researcher. You’re on the front lines for advancements in the field. What led you to there and why is it so important to you?  

Dr. Hobbs:

Many things in my life led me to becoming an MPN clinician. First, I wanted to be a clinical investigator since I was very little, and I read a Louis Pasteur book about – you know. And I was fascinated by the fact that you could be both a scientist and a clinician. And after that, I had phenomenal teachers and mentors. And I was really always drawn to patients with hematologic malignancies. I thought that that interaction was very intense and intimate.  

And I was honored to be a part of that interaction. And then from a research perspective and from a scientific perspective, I very clearly remember seeing when the first targeted therapy, Imatinib, was approved when I was an undergrad. And I just thought that was the most fascinating thing. And so, I’ve basically continued to feel that way as I’ve gone through my training and I’m thrilled to be able to have actually become an MPN clinician so many years later.  

Katherine:

With the American Society of Hematology or ASH meeting taking place this month, it demonstrates how researchers work together around the world to advance care.   

Can you share with the audience how this collaboration works?  

Dr. Hobbs:

Yeah. So, the American Society of Hematology meeting – or the ASH meeting – is really one of my favorite events of the year.  

And it really highlights what you said. It is such a positive environment, and it’s so exciting to use that opportunity to talk to my collaborators from across the globe. And I really think that that’s where the scientific community shines because really all of us are actually trying to figure out how to work together and overcome sometimes a lot of obstacles – bureaucratic obstacles, regulatory obstacles – to make sure that we can share data, do it the right way. But really we always have one thing in mind.  

And that is to be able to advance the care that we give our patients. And so, that collaboration and really that collaborative environment is always very positive. And I always come back home very energized from that. And then just seeing all my colleagues presenting all the wonderful things that they are working on and getting updates on their research is just an exciting environment.   

Katherine:

In your view, why is it essential to present and share data at these larger conferences like ASH? 

 Dr. Hobbs:

So, for many different reasons. I mean, there are many different ways of presenting data that can be done through just publishing a paper. But the nice thing about conferences – and especially large conferences – is that you really get an opportunity to present work in progress. And some of these research projects may not end up turning into bigger projects or they may not become bigger trials. But all of them have at least an opportunity to learn something from them, whether or not they worked or they didn’t work.  

Oftentimes when things are published in journals, especially the high-impact journals, we are seeing trials that had positive results. But sometimes we don’t see those smaller trials that never went anywhere. And so, having a forum when we can discuss work that’s ongoing, discuss about projects that are maybe having issues, all those things actually really help us to change our research questions or develop new research questions based on what’s working and also really what’s not working. And so, having this large forum to present all of that data, I think, is really, really important to helping us design future clinical trials and projects.  

Katherine:

Yeah. Well, this is a great way to begin our clinical trial discussion, Dr. Hobbs. This research all requires MPN patients to participate in clinical trials. So, what should be considered when deciding whether to join a trial? 

Dr. Hobbs:

What a great question. Many things need to be considered when joining a trial. And I think some patients are really eager to join a trial, and they just need to be aware that they may be either too healthy, or they may have other things going on that may not make them eligible.  

And that’s okay. There are actually many ways of participating in research, even if it’s not a clinical trial that requires a medicine. For example, we often can send patients to what’s called a tissue bank where they have patients just give a sample of blood.  

So, patients can participate in research in many different ways. When considering whether or not a patient should enroll in an actual clinical trial with a new medicine, I think it’s really important for the patients to be informed and to not be afraid to ask questions. First, what is a clinical trial? Second, what will this trial involve? Is this a drug that has never been given to people before, or is this a drug that has already undergone many different clinical trials? And this trial that’s being offered is a Phase III trial where the purpose of the study is to get the drug to be approved.  

So, I think learning about the risk of the study, how it’s been utilized. And also the other more practical things. What is the time commitment of this clinical trial? How often are you going to have to be going to the office because of the clinical trial? Because there’s certainly a big investment in the part of the patients in terms of their time. Participating in a clinical trial most of the time requires more time than not participating in a clinical trial. That’s not always the case. There are some studies that definitely don’t require that many visits.  

But most clinical trials will require at least something extra from the patient. And I think it’s really important to ask about that, to read the consent that’s given to the patients. Oftentimes these consents are very long.  

And so, they can be overwhelming. I personally find them overwhelming. And I review a lot of those consents. And so, I think taking a minute to really ask those questions, speaking to the research staff, and getting the clarification on that is really important.  

Like you said, it is impossible to approve new therapies and improve the care that we offer our patients without patients participating in the clinical trial. But that doesn’t mean that absolutely every single patient needs to participate in a clinical trial if it just doesn’t make sense for them. [14:17]  

Katherine:

There have been huge developments in the last 10 to 15 years in the field of MPN. So, I’d like to dig a little deeper. We hear about the common driver mutations in MPNs like JAK2, CALR, and MPL. How are these being studied , and what is being discovered? 

Dr. Hobbs:

Yeah. So, it’s amazing how in the last 15 years really so much has been discovered. You know. The JAK2 mutation was first published out in 2005 and calreticulin in 2013. So, those are relatively recent discoveries. And I think a lot of efforts has been put into learning about what these mutations are doing and how they lead to disease. And so, we have the JAK inhibitors, which block the signaling through a pathway called JAK-STAT. And all of these mutations will activate that pathway within cells.  

And so, many of the approved drugs, for example, ruxolitinib (Jakafi), fedratinib (Inrebic), and pacritinib (Vonjo), work on blocking that pathway.  

But since then we’ve also learned that there are other mutations and other pathways that are likely involved in the development of myeloproliferative neoplasms and also their progression. And so, what we’re seeing now is that many of the clinical trials that are being conducted don’t just target the JAK-STAT pathway or the pathway that’s influenced by these main mutations.  

But also block other pathways to try to really block all the variant expression of signaling in the myeloproliferative neoplasms. And so, we’re trying to attack it by many different angles.  

Katherine:

Yeah. Is there a possibility of specific targeted therapies at MPNs similar to those in AML such as FLT3 inhibitors? 

Dr. Hobbs:

Absolutely. So, similarly to AML, we know that we have mutations in similar types of genes called tyrosine kinases. So, these are enzymes that are turned on and always active. And so, I think there is definitely hope that we can develop some targeted agents. For example, ruxolitinib or the other JAK inhibitors are similar. They’re tyrosine kinase inhibitors where they block an enzyme, specifically the JAK2 enzyme.  

But I think that we can definitely do better and develop more specific inhibitors, for example, a molecule that just blocks the JAK2 mutation and not just every JAK2 molecule in every cell. Similarly to AML, there are mutations, for example, in enzymes called IDH.  

And we have IDH inhibitors for AML. And there are some studies that are using IDH inhibitors for MPN. So, I think we’re going to continue to see more targeted therapies specific to the mutations that occur in MPN.  

Katherine:

Yeah. Let’s talk about ET for a moment. Is there any research being done to help better manage this condition? 

Dr. Hobbs:

Yeah. I would say that of the three MPNs, ET is certainly the one that has the least amount of drugs that are being currently studied for this group. But that doesn’t mean that there isn’t any research. Ropeginterferon (Besremi), which was recently approved in polycythemia vera, is now being studied in essential thrombocythemia.  

So, I would expect in the next couple of years, if those trials are successful, to have ropeginterferon as a therapy to offer patients. There is also a clinical trial that we have at our site.  

We’re using ruxolitinib or Jakafi for patients with ET that have symptoms of their disease to see if it can help them in the same way that it can help PV or myelofibrosis patients. So, there’s definitely some research going on in ET. But probably less than for PV and myelofibrosis.  

Katherine:

Mm-hmm. While ET is typically well-managed, what patient type might benefit from joining a trial? 

Dr. Hobbs:

It really depends on what the patient is experiencing. I think there are some patients that really are very asymptomatic and can expect to have an excellent outcome with their disease. But they can also participate in research, for example, by participating in a tissue bank and offering a sample of their blood or if they have a bone marrow by offering some bone marrow if there’s extra. Because that can really help to understand the disease biology, if a patient is going to progress from ET to myelofibrosis.  

So, we can learn a lot from that. But then there are maybe some ET patients that need to be on a medication to reduce their blood counts or a cytoreductive agent.  

And that’s a patient that could ask about participation in a clinical trial. For example, the ropeginterferon study or, like I mentioned, there may be some patients that maybe are already on a medication and their blood counts aren’t well controlled on the first drug that was used.  

So, before considering switching to a second-line agent or a second medication, that could inquire with their clinician if there’s a clinical trial available for second-line use. Or those patients that have a lot of symptoms with ET, they could potentially be eligible for a study that addresses just symptoms.  

Katherine:

Right. That’s really good news. I’m glad you talked about that.  

Dr. Hobbs:

Mm-hmm.  

Katherine:

There was recently an interferon approved for use in patients with PV. What other studies are showing promise for patients with PV?  

Dr. Hobbs:

Yeah. So, we as a community, there’s been a lot of excitement about this new interferon that was approved, the ropeginterferon study. And there are still some ongoing studies utilizing ropeginterferon to see if we can use it differently. Because currently the way that that drug is approved is that it has to be titrated up very slowly to get to the maximum dose. So, that’s something that is still ongoing. In addition, there’s a new drug that’s being studied called Rusfertide (PTG-300) from a company called Protagonist. And this drug has been very interesting. It acts through iron metabolism.   

And so far in preliminary results, it has shown that a lot of the participants that receive this medication no longer need phlebotomy. And I think what’s exciting about this is that phlebotomy is a very archaic way of treating patients.  

And I hope that we can stop utilizing it. So, it’s nice to have a compound that’s specifically asking that question. And the other thing to keep in mind is that this drug has been used in combination with other drugs, which is really reflective of how participants or patients show up to clinics.  

Some patients are not going to be on any medications. Some patients may be on hydroxyurea.  

Some patients may be on an interferon. Some patients may be on Jakafi. And these trials allow participants to be on a variety of different medications. So, that’s an exciting new compound.  

Katherine:

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

Dr. Hobbs:

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

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

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

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

Katherine:

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

Dr. Hobbs:

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

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

Katherine:

Yeah. I’d like to get specific about your research. What are you excited about right now? 

Dr. Hobbs:

A few different things. There’s a clinical trial that I’ve been leading for several years now that got somewhat delayed due to the pandemic that’s utilizing ruxolitinib before, during, and after transplantation for patients with Myelofibrosis.  

And that study is hopefully going to finish accrual in the next couple of months. So, I’m excited to see the results of that study. That study was presented at ASH of last year, the interim results of that study. And so far, we’ve seen exciting results. Patients have done well with transplant while receiving ruxolitinib.  

We’ve seen that patients that have undergone transplant and have received ruxolitinib have had very low rates of a complication of transplant called graft-versus-host disease.   

And that’s been very exciting, because we know that graft-versus-host disease is really very difficult to deal with after transplant. It can really impact quality of life. And so, that’s been exciting to see that we can help our patients to better tolerate this difficult treatment. On the complete opposite end of the spectrum, we’re treating patients that have low-risk essential thrombocythemia and polycythemia vera with ruxolitinib also to see if their quality of life can improve.  

We know that patients with ET and PV live with a lot of symptoms. And often times patients that are considered low-risk can still have a lot of symptoms. And therapies haven’t really specifically been studied just to improve symptoms. Really, therapies are usually used to reduce the risk of having blood clots.  

Katherine:

What about checkpoint inhibitors? You’ve done a study about that? Or it’s ongoing? 

Dr. Hobbs:

Yes. Great question. So, a few years ago we utilized a checkpoint inhibitor called Pembrolizumab for patients with advanced myeloproliferative neoplasms. And that study was open at Mass General and also at Mount Sinai. We were worried that it wouldn’t be well tolerated. But it was actually very well tolerated. But unfortunately patients didn’t have a response. And a group at MD Anderson utilized another checkpoint inhibitor, Nivolumab, for these patients. And similarly they also didn’t see a response.  

So, that was disappointing. However, I do think that there is a role for immunotherapy in patients with MPNs. I think that we probably need to think about utilizing the checkpoint inhibitors maybe earlier or maybe in combination with other agents. This has been done, for example, in solid tumors where two checkpoint inhibitors are sometimes utilized together. So, I think their area of investigation is still worth pursuing even though that was a disappointing result.  

Katherine:

Yeah. Yeah. Any other research that’s going on that you’re doing? 

Dr. Hobbs:

Yeah. We are looking forward to opening some clinical trials using different drugs in combination with ruxolitinib to offer different treatments to our patients up front. And so, instead of offering just single-agent JAK inhibitor, we can combine that with one of the new agents. And so, I’m looking forward to seeing how that’s going to work for my patients and to be able to offer them another treatment. I’m also thinking of developing a clinical trial for use in patients that have clonal hematopoiesis.  

So, patients that have this entity called CHIP where they have a JAK2 mutation but maybe don’t have overt disease. We know that they have a high rate of transformation to an actual MPN. So, we’re working to develop clinical trials for those patients with the hope of maybe preventing the MPN from ever happening. 

Katherine:

That’s great. We have some questions from the audience that were sent in prior to the program. Carl asks, “Are MPNs inherited? And why does one sibling develop an MPN and the other does not?”  

Dr. Hobbs:

Great question. So, historically, we’ve always said MPNs are very rarely inherited. Now that we’re able to test for JAK2 mutations more commonly, we have, I think over the last decades, probably found that there are more families where the MPNs kind of run in the family.  

Katherine:

Mm-hmm.  

Dr. Hobbs:

Generally speaking, it’s very rare for MPNs to run in the family. I would say less than 10 percent of the case. And this is why a sibling can have an MPN and one doesn’t, even if they’re identical twins.  

Katherine:

Is research being done to learn more about who may be at risk for developing an MPN? 

Dr. Hobbs:

So, over the list, there’s been a lot of attention placed on this entity called clonal hematopoiesis of indeterminate potential. And through those types of investigations, we’ve learned that people can actually live with a JAK2 mutation for many years, even decades, before they develop a myeloproliferative neoplasm. And so, indirectly, I think that type of research will help us understand why some people get the JAK2 mutation to begin with and what else needs to happen in a patient’s life for that person to develop an MPN.  

Because clearly there are many more people walking around with a JAK2 mutation than there are people with an actual MPN. So, there’s something else other than that JAK2 mutation that predisposes patients to then develop an MPN.  

Katherine:

Angela has another question. “What are the long-term effects of JAK inhibitors? And what happens when JAK inhibitors are no longer effective?” 

Dr. Hobbs:

Yeah. Great question. So, so far the patients that have been on JAK inhibitors for a long time don’t seem to have the development of additional toxicities that we didn’t know about. So, I’ll just comment on some of the things that we do know about. Weight gain is a common complaint that I have from patients, especially those that have polycythemia vera, because maybe they didn’t want to gain weight when they were put on a JAK inhibitor compared to the myelofibrosis patients who maybe had lost a lot of weight before being on a JAK inhibitor.  

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

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

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

Katherine:

Mm-hmm. Gary has two questions for you. The first is, “How useful is having a genetic panel done? Should all patients get molecular or genetic testing?” 

Dr. Hobbs:

Great question. And I think that it is very important to have genetic testing.  

And genetic testing involves more than just testing the JAK2 mutation. So, we know that the JAK2 mutation is the most common mutation in patients with MPN. But that being said, there are other mutations that also occur such as the calreticulin mutation and the MPL mutation. And so, I think having genetic testing that at least tests for those three mutations is very important so that we can actually help a patient know that they have an MPN. In addition to those three main mutations, many clinicians now have access to what’s called extended next-generation sequencing, where there’s a panel that tests for many different genes at the same time and can test for a variety of other mutations.  

And this is particularly relevant for patients with myelofibrosis. As we know that having other mutations, like, for example, mutations in IDH or ASXL1 and others, can increase the risk of that disease in terms of its risk of transforming to leukemia or how long a patient may live with their myelofibrosis. 

And so, I do recommend having extended next-generation sequencing done at least at diagnosis.  

When I generally think about repeating that, if there’s something that looks like it’s changing within the patient’s disease, to be honest, also on the flipside of that argument, sometimes this next-generation sequencing will mostly contribute to adding anxiety and will not necessarily directly impact how a patient is treated. And this is particularly true in patients with PV and ET, where we’ll sometimes order these tests, and we get a bunch of mutations back, but we don’t know what to do with that information yet.   

And so, as a researcher – not a clinician – as a researcher, I think it’s very important to have that information so that we can then do studies and understand the patterns of mutations and how that affects outcome. But as a clinician, and you as a patient, you need to really be aware of how that’s going to impact the patient in front of you and how that may impact you as a patient. Do you want to know if you have these mutations if nothing can be done about it? So, I would say, take a moment to reflect upon what I said and also to ask your clinician, how is this information going to help me? Do I need to have this information?  

Maybe you want to have it done so that it’s in your record. But maybe you don’t necessarily want to know those results. And everybody’s very different. And I think it’s absolutely wonderful to talk to my patients about all the information. But there may be some patients that really are just, like, do the test but don’t tell me the results, because I know that I’m just going to be very anxious knowing that I have something that I can’t do anything about. So, just take a minute to talk about it with your doctors. I think that’s really important.  

Katherine:

Yeah. Yeah. Here’s Gary’s second question. “Is allele burden a key predictor of progression?” And before you answer that, Dr. Hobbs, what does “allele burden” mean, and how does it impact progression? 

Dr. Hobbs:

Great questions. And I hope that in the next couple years I have a much better answer for you. So, maybe I’ll come back again and maybe we can talk about this again. So, allele burden – just simply put – is basically, like, how many of the stem cells in your bone marrow have that JAK2 mutation. And that’s a concept that’s not obvious. So, not all of a patient’s blood with an MPN has that JAK2 mutation. There are some stem cells that have the JAK2 mutation and produce JAK2-mutated blood. And then there are some stem cells that are normal that just make normal blood and don’t have a JAK2 mutation.  

And so, we can measure, what is a proportion of cells in the blood that has that JAK2 mutation? Now the next question should be very obvious and straightforward. But it really is not. So, what do we do with allele burden, and how do we measure that, and what does it mean if the allele burden goes up or it goes down? At this moment, we don’t necessarily know that. There have been some studies showing that maybe higher JAK2 mutation burden is maybe associated with progression or more with PV as opposed to ET.  

And we’d all like to think that lowering that JAK2 mutation level or that JAK2 allele burden has to be good and maybe will decrease progression or improve survival. We haven’t seen that yet. And so, I think we’re all really waiting to see, what does it mean to lower that JAK2 allele burden? And then how often should we be measuring that? But right now we really don’t know.  

Katherine:

Yeah. One more question for you. This one from Joseph. “I have PV and had adverse side effects from peginterferon alfa-2a (Pegasys). Is it likely that similar side effects would be experienced with Besremi?” 

Dr. Hobbs:

Good question. It’s hard to know. And it really depends on the severity of the side effects that you had and the type of side effect that you had. In my experience, ropeginterferon or Besremii is very well-tolerated compared to the other interferons that were available. But if you really had a severe side effect it may be difficult to consider trying it. But it’s worth considering it. I’ve definitely had patients that have gone from Pegasys to ropeginterferon without any difficulty. But just because you had a bad side effect to one doesn’t mean that you’ll have a bad side effect to the other.  

Katherine:

This is from Paul who lives in the United Kingdom. “How important is it to see an MPN specialist rather than a general hematologist? Right now I’m currently seeing a general hematologist who makes a note of my side effects but offers no coping strategies or solutions.” 

Dr. Hobbs:

Yeah. That is a great question. And one with not one answer. I would say that if you’re an MPN patient and you have a clinician that treats you that feels comfortable treating you or you feel heard and you’re being offered different ways of dealing with symptoms or side effects, etc., then perhaps you don’t have to go out of your way to find an MPN clinician. And participating in webinars like this or learning online may be sufficient to know how to advocate for yourself and how to monitor your disease. That being said, I do think that it’s nice for patients to at least have a one-time opinion with a specialist.  

And I would say that with the advent of virtual care, that has become increasingly more accessible. And so, if that’s something that’s available to you, that’s something you should consider. You know. Sometimes it’s very difficult to travel a long distance to meet with a specialist. But if you can avoid the travel by having a virtual visit, that often times can be very helpful in just knowing that you’ve met with somebody once. And then you can meet with that person periodically throughout your care can be very helpful. And I’ll tell you personally I see patients in the neighboring states to where I live.  

And I like to see those patients periodically or communicate with their local providers. And so, it just helps to offer care that’s very specialized in maybe areas of the country that don’t necessarily have access to specialized care. So, I would encourage patients to seek that out if that’s something that they’re interested in because it’s really become, I think, easier to access the specialists.  

Katherine:

Thank you for your thoughtful responses. And viewers please continue to send in your questions to question@powerfulpatients.org. Before we end the program, Dr. Hobbs, I’d like to hear why you’re hopeful about the future MPN care.   

Dr. Hobbs:

Thank you so much. Those are great questions. I feel very hopeful about the future of MPN. As we mentioned at the beginning of this webinar, the scientific community and the MPN community of clinicians and investigators, it’s such a nice example of how scientists can work together to improve the care of patients. That I always feel very inspired by my colleagues. And now that ASH is around the corner, I can tell you that I feel very hopeful for the future of MPNs because I know that we’re going to learn about a variety of different clinical trials that are showing promising results that are going to ultimately impact the way that we are able to treat our patients with MPN.   

And lastly, I feel very hopeful for the future of MPN because I know that the MPN community is very active. Patients participate in webinars like this, belong to different online groups, and are excellent advocates for themselves. I’ve seen firsthand in my clinic how when a drug gets approved, patients learn about new treatments online and come and ask for them. And so, I just feel very honored to be a clinician that is able to treat a group of patients that can advocate so well for themselves. And so, I definitely see lots of changes in the next couple years.

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!

Katherine Banwell:

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

Dr. Scandura:

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

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

Katherine:

Right. Right. 

Dr. Scandura:

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

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

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

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

Katherine 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.”
