Katherine Banwell:

What are your areas of focus in myelofibrosis research? 

Dr. Idoroenyi Amanam:

So, I think the way that I would break it down, when you think about myelofibrosis patients, or patients with myeloproliferative disorders, patients who are diagnosed, and they’re really pretty much asymptomatic, and then you have patients who have some symptoms, then you have some patients who are very symptomatic or transitioning into a more severe disease and predominantly, that disease is acute leukemia. And so, I have an interest in trying to identify new treatments for all of these types of patients.  

Katherine Banwell:

In your opinion, what new myelofibrosis advances are most promising? 

Dr. Idoroenyi Amanam:

So, traditionally, for a lot of myeloproliferative disorders, including myelofibrosis, we had a watch and wait approach, so we typically actually did not really have very good therapies. And I think all of that changed with the approval of the first JAK inhibitor, ruxolitinib (Jakafi).  

And we have transitioned to understanding the signaling pathways that are involved in myelofibrosis and myeloproliferative disorders. And we understand certain driver mutations that are involved in these signaling pathways and involved in other areas that help drive these diseases.  

And I think what’s exciting for us right now is, we’re transitioning from having a Band-Aid approach, or a watching and wait approach, to actually having interventions that are what I would call disease-modifying drugs. And so, these drugs target some of these drivers that drive the disease.  

They target some of the inflammation that’s associated with the disease, and, in fact, they’re also targeting some of our own immune cells that may help us protect us against these diseases progressing into more aggressive disorders. 

Katherine Banwell:

How are innovations in technology accelerating myelofibrosis research?  

Dr. Idoroenyi Amanam:

You think about how we understood these diseases 20 to 30 years ago. I think we understood the clinical presentation. We understood that some patients had big spleens, we understood that those patients’ counts didn’t do so well, we understood when we would look at their marrow, how the cells looked under the microscope. And we’ve transitioned to now understanding how some of those proteins that are   in these  signaling pathways are either turned on or turned off.    

We have a better understanding of the genetics of this disease, and how it changes over time, and what that means for patients prognostically, and how they will actually respond to our current therapies.  

And obviously, it’s driving how we are setting up clinical trials and other therapies  for the future. And so, I really would say our  genetic, genomic understanding of these disorders have really opened up many opportunities for us to treat these patients better.  

Katherine Banwell:

Well, are there other research developments showing promise that patients should know about? 

Dr. Idoroenyi Amanam:

So, traditionally, we’ve thought about  these disorders as disorders where, maybe if we improved symptoms – so we give you, maybe, a pill that would help with your symptoms, or we’ll give you another medication that will help with keeping your counts under control or reducing your risk for clotting and stroke.  

And we are currently in a space where cellular therapy has exploded across all areas of oncology. We have many clinical trials that are using  therapies that  take your own cells,  or other donor cells from healthy  people, and we are giving them to patients with the hope that it will  get rid of these  bad cells that are driving myelofibrosis.  

Expert Outlook | New Myelofibrosis Therapies Showing Promise

 

What myelofibrosis therapies in development show promise? Dr. John Mascarenhas, a myelofibrosis researcher, reviews innovative treatments that are being combined with JAK inhibitors as well as single agent therapies that are making headway for patients with myelofibrosis.

Katherine Banwell:

The JAK inhibitor class of therapies has been around for over a decade now. What new therapies are showing promise when being studied in combination with these therapies? 

Dr. John Mascarenhas:

So, I think the ones that are really exciting, and there are a number. We don’t know which one is the best, but I’ll tell you the ones that I think really have potential would be drugs like pelabresib, the pan-BET inhibitor, and the MANIFEST-2 study. Even a drug called navitoclax, that isn’t going to move forward, taught us a lot. We know that pathway is important, we just have to improve upon how we’re doing this.

Drugs like selinexor (Xpovio), the XPO1 inhibitor, is ongoing in the SENTRY study. A drug called navtemadlin is a very active drug, and that’s been shown as a single agent after ruxolitinib (Jakafi) failure. But now, it’s going after those patients who are not having an optimal response with ruxolitinib, adding it on on the backend.  

So, what I really love about the way we’re doing this is, I think it’s a very thoughtful approach trying to use these really active drugs that exploit non-redundant pathways in the disease, both either up front, to really get the biggest bang for your buck, to really try to reduce the diseased burden earlier on, or to try to add on as a strategy if patients aren’t enjoying the maximum benefit from ruxolitinib. So, we are really trying to tackle it from different angles and some of these drugs really look promising. 

Katherine Banwell:

Yeah, yeah. Are there other single agent therapies that are being studied for myelofibrosis?  

Dr. John Mascarenhas:

There are. So, I’ll name two that I also think really deserve some attention. One is called TP-3654, and it’s a drug by Sumitomo that’s a PIM 1 kinase inhibitor. So, this also goes after a very specific pathway – inflammatory pathway – a signaling pathway – that is known to be an important driver of disease and has very nice data, particularly from a symptom-burden perspective. But also, again, this concept of disease modulation and reduction in cytokines in patients who’ve previously been on ruxolitinib.  

So, there’s data there where they’re going to add it on to ruxolitinib that really looks like an interesting approach forward. And then the drug I think many of us are very anxious to see results in which is ongoing, is the IMpactMF study.   

This is the randomized phase three study of imetelstat (Rytelo), which is a telomerase inhibitor and infusional agent that goes after a very important enzyme that keeps malignant cells alive and really is one of the drugs that I think has the true potential to go after the stem cell, the origin of the disease, and improve survival. It’s the only study we have had, and currently have, where the endpoint for the registration phase we’ve studied is survival. It’s patients who have failed ruxolitinib and are getting this drug as a single agent, versus best available therapy.  

A very exciting trial and really important. Whether you’re on the trial or you’re a candidate for it, it really helps us move the field forward, because it gives us essential insights into the disease and how to do better. 

Katherine Banwell:

Yeah. When it comes to the latest research and treatment, what question should patients ask their health care team about new or developing treatment options? 

 Dr. John Mascarenhas:

Well, I think every patient is different, and truly different since their biology is different, the way they present is different, their course is different. So, really, the treatment options, including the trial options, really need to be tailored to the patient. It has to make sense for that patient. It has to meet their expectations, be aligned with their goals of therapy, and balance. Balance risk with potential benefit. Patients have to understand. The physicians have to present very clearly that some trials are randomized studies, and you could get a placebo. 

And it’s often blinded, so the patient doesn’t know, the physician doesn’t know. But importantly, in some of these studies, there’s crossovers, so even if you don’t get the drug up front, you can get it in the backend. All of these things really have to be disclosed very carefully and thoughtfully, so the patient’s really making an informed decision that makes sense for them and is meeting their expectations.

Lisa Hatfield:

Dr. Kuykendall. I’d like you to speak to some of the key challenges in managing MPN symptoms. So based on the available treatment options, what are the most challenging symptoms associated with polycythemia vera, PV, or myelofibrosis and essential thrombocythemia, ET? And what are we learning about how these symptoms evolve as the disease progresses? 

Dr. Andrew Kuykendall:

When we think about myelofibrosis, that’s probably the disease we associate with the most clear, distinct symptoms. And patients often have what we call “constitutional symptoms.” And this could be fevers, chills, night sweats, bone pain, weight loss. These are classic symptoms of a disease that is really causing a lot of inflammation, right? And driving a lot of these inflammatory pathways, and these types of symptoms are quite well-addressed with JAK inhibitors, these disease specific anti-inflammatories, of which we now have four that are approved for myelofibrosis in different capacities. But there are more symptoms beyond those. I think when we think about polycythemia vera, we get less constitutional symptoms, although that certainly can be seen in a subset of patients.

But we see more itching is probably the classic polycythemia vera symptom. This itching that is quite challenging, doesn’t necessarily respond to antihistamines, and can be something that’s exacerbated by like taking hot showers or being in hot water. There’s a fancy name for it called aquagenic pruritus. And patients may not even be aware this is related to their disease. I’ve met many patients who’ve come in, who’ve been diagnosed with PV who complain of this challenge with showering or being in hot water, who really never put two and two together.

And sometimes the itching isn’t even described as itching. It feels like fire ants all over their body. And you have patients that are really avoiding right, showering. And so they’re doing it maybe once a week or once every two weeks. And so again, this is a symptom that responds quite well to ruxolitinib (Jakafi), which is approved in the second line here.

Beyond that, I think the biggest symptom across myeloproliferative neoplasms is fatigue. And I don’t have great magic tips for fatigue other than to say what we found out is probably non-pharmacologic interventions are better than pharmacologic interventions for fatigue. Things like just making sure you have good sleep hygiene, getting good sleep, healthy diet, exercise, yoga, mindfulness, resting, these probably are more successful in treating fatigue than any specific drug or agent that we have. And I think that speaks to really a failure on our part to develop better therapies. But certainly it’s something that we’re all very well aware of. And so it’s something we monitor in any of our clinical trials when we are developing agents is how does fatigue change over time? And lastly, I’d say for ET I think you can start to see some symptoms that are more kind of neurovascular.

So things like headaches, migraines, ringing in the ears, or tinnitus, or tinnitus. These can be unique to ET and may predate or preempt the actual diagnosis. So a lot of our young patients that are diagnosed with ET may come to attention of physicians because they’ve been dealing with migraines or headaches or fatigue plus migraines and headaches for a long time. Then lo and behold, blood work shows that they have a very high platelet count.

And so over time, I think when we look at these symptoms, certainly there can be waxing and waning of some symptoms, response to therapies, lack of response to therapies. But if the symptoms really do change rapidly, which we don’t see that often, oftentimes this can accompany a change in the disease, right? And that’s the time to go in and see if something’s changed. Sometimes reevaluate the disease status. And so my [ACT]IVATION tip for this is that we have a variety of symptoms that can be associated with kind of myeloproliferative neoplasms as a whole, as well as each one of these distinct disease entities. And the therapy for each of these differs based on the particular symptom.

Lisa Hatfield:

Dr. Kuykendall, since current treatments may help control polycythemia vera but don’t significantly improve symptoms, what steps are being taken to develop new therapies that not only control PV, but also improve patients’ overall quality of life? 

Dr. Andrew Kuykendall:

Yeah, so right now the therapies we have for polycythemia vera essentially the main goal is to reduce as I tell patients, to reduce the things that could kill you, right? To reduce the risk of thrombotic events, cardiovascular events, strokes, blood clots, heart attacks, things like that. As we know that that is a huge issue for these patients that are at increased risk for cardiovascular events.

So we do that with a variety of different strategies, but I think increasingly what we’re realizing is we need to make a primary focus of treatment being on improving and maximizing quality of life. And this is something that really we should be thinking about across all malignancies. But specifically polycythemia vera (PV), where this is a disease that if we are able to avoid some of these cardiovascular events, patients have a very good quantity of life expected with their disease.

So they may live with their disease for 15, 20, 30 years. So if that’s the case, we really need to be thinking about how we can do that as best as possible, right? We’re talking about a third of your life living with this disease. And so we need to do that in a quality way. So agents like ruxolitinib (Jakafi) that have been approved for polycythemia vera in the second-line setting.

Ruxolitinib is known that it is improving some of the disease-related symptoms that come with PV, fevers, chills, itching, night sweats, bone pain really does help with those things. But I think that we can move beyond that. And we’re developing agents like rusfertide. Rusfertide is the hepcidin mimetic that is aiming to reduce the amount of phlebotomies patients need. And for me, that’s important in a variety of ways.

One if you don’t need to get phlebotomies all the time, you’re not tied to the healthcare system, right? Nearly as much. And that could be a huge dissatisfactor. And so at the same time, getting a phlebotomy is not that fun either. It requires going in and sitting there getting blood drawn, you may get lightheaded, fatigued that comes with that.

So eliminating that aspect of negative quality of life. At the same time, we’re starting to see with rusfertide whispers that it may help with some of these symptoms that may be related to iron deficiency. Things like brain fog, concentration issues, fatigue. And so if we can help a little bit with that aspect of things too, man, we could start to kind of, you know, chip away at some of the quality of life issues that are ongoing.

And then down the road, I think some of these JAK2-specific inhibitors may have the continued ability to modify the underlying disease. And certainly that’s a huge goal, right? If we can actually start to get true responses really get at the core of the disease to get the disease to go away. And I think that ultimately that will hopefully result in better quality of life as well. So, at the same time, I think my [ACT]IVATION tip for this question is that there’s a lot of things that factor into a suboptimal quality of life for patients with PV. And we need to think about all of those as we try to chip away and make patients’ quality of life as good as possible.

Lisa Hatfield:

Okay. Thank you. And is there any hope of any of these newer therapies being of limited duration, or are all of them continuous therapy? Because I know as a patient myself, that quality of life is impacted by knowing that I’ll be on therapy forever, some kind of therapy forever. Any hope for that? 

Dr. Andrew Kuykendall:

Yeah, so certainly with some agents there is hope for that. So some of the agents I referenced, ruxolitinib, rusfertide, these are agents that probably are, are going to be continued therapy. We always call it indefinite, right? As long as we think that the benefits outweigh the risks, we continue that. If we stop those, typically the reasons we’re using them, those come back quite quickly.

But I would say it’s not necessarily the case with agents like interferon. So interferon is an agent that’s less associated with symptomatic improvement, although we do see it in a subset of patients, it’s more associated with the ability to potentially modify the underlying disease. And so what we’ve seen with interferon is that we can measure patients’ JAK2 allele burdens, the number of cells that have the JAK2 mutation that drives the disease.

And in patients that are on interferon for 2, 3, 4 years, we see the number of cells that have the JAK2 mutation go down over time quite consistently. And even in the case that in some patients it goes less than 10 percent or to a level, we really can’t pick it up with our standard testing. And my experience with that is we can actually stop interferon in some of these patients for a pretty extended period of time.

So we have patients where we stopped for one or two years with blood counts that remain quite well-controlled, patients feeling well. In time, we might have to restart it as things start to to pop up, but I think that we are starting to get to these kind of at least treatment reductions, dose reductions where we can spread things out, but also kind of brief treatment interruptions where we get this kind of treatment-free period that certainly can be attractive to some patients.

Lisa Hatfield:

Okay. Thank you. And I’ll just do a quick shoutout to physicians like yourself who deal primarily with MPNs or work a lot with MPNs, that if a patient is watching this and doesn’t have somebody who really specializes in MPNs, everything you’re talking about, clinical trials, it might be helpful even to just get a consult or what I call an expert or second opinion on how to manage your MPNs. So anyway, thought I’d throw that out there. Thank you.

Can Monitoring Albumin Levels Help Track Myelofibrosis Treatment Success?

How might albumin levels help guide myeloproliferative neoplasm (MPN) care? Expert Dr. Andrew Kuykendall from Moffitt Cancer Center discusses research on albumin monitoring and treatment for myelofibrosis and polycythemia vera, treatment response, spleen size, and proactive patient advice. 

[ACT]IVATION TIP

“...monitor your lab work. Use everything at your fingertips to kind of get a sense for how something’s working. So whether it’s albumin level or spleen size or symptoms…really take everything into account to know if the treatment’s working for you.”

Lisa Hatfield:

Dr. Kuykendall, your research shows that changes in serum or blood albumin levels are linked to better survival in myelofibrosis patients treated with ruxolitinib (Jakafi). How could this information help doctors monitor patient progress and adjust treatment plans over time? 

Dr. Andrew Kuykendall:

Yeah, so this is a bit of a passion project for me that I spent a few years looking at. Want to give a little bit of a backstory. Ruxolitinib is a JAK inhibitor that is approved for myelofibrosis as well as polycythemia vera. And what it’s able to do, the way to think about,  it’s like a disease-specific anti-inflammatory. And so the disease itself kind of ramps up these inflammatory pathways, ruxolitinib blocks those inflammatory pathways, and it improves patients’ symptoms.

It’s also been able to show kind of reduction in splenomegaly or enlarged spleen for patients, but it doesn’t really get rid of disease, right? So we’d like it to be better than it is. We’d like it to get rid of the bone marrow disease and get so-called complete response or complete remission. But we don’t see that.

However, we know that it helps a lot of patients. And I think that the challenge is knowing when it’s helping someone and when to continue it versus when should you consider alternative options? And we’ve really struggled with kind of coming up with an objective definition of how to kind of define treatment success or failure with this. And so the best data we have supports patients that have a spleen response tend to have better survival than those patients that don’t have a spleen response.

However, we’re not routinely imaging patients’ spleens in the clinic, and many patients it’s difficult to monitor their spleen kind of growth or reduction in size on exam. And so this not isn’t always the most feasible way to monitor kind of response to therapy. And symptoms…they can be variable.

Certainly if patients are feeling better, that’s a great thing, but a lot of things factor into symptoms. And so kind of on a week to week, month to month, visit to visit basis, that may be challenging. And so I was very interested in looking at albumin, which I think kind of factors into a lot of things regarding health. So patients that are more nutritionally optimized have better albumin levels, patients that have less inflammation just in general have better albumin levels and patients that are eating well have better albumin levels.

And actually I kind of harkened back to a trial that was published on ruxolitinib-treated patients that showed that patients who got ruxolitinib, their albumin levels rose over time. And that was intriguing to me, which was the thought was, okay, well if that happens, if this is something specific to ruxolitinib, does this… Is this something that that can actually define those patients that do well? 

Does this represent someone who’s able to eat better and be more nutritionally optimized? Does this represent someone who’s getting a really good anti-inflammatory benefit from ruxolitinib? And so we looked at our patients and actually combined our data sets with an Italian data set as well, and showed that those patients on ruxolitinib whose albumin either stayed the same or improved, actually derived a survival benefit compared to those whose albumin levels stayed the…or whose albumin levels decreased over time.

And that was unique to ruxolitinib when we looked at patients who weren’t treated with ruxolitinib, who had myelofibrosis, we didn’t see the same pattern. And so the reason I think this is interesting and potentially clinically relevant, is that we’re always looking at albumin levels. The albumin is involved in kind of the complete metabolic panel or the CMP that we routinely are getting on patients.

And so this is something that’s very available to physicians as they’re watching someone on ruxolitinib. And so they can look and say, oh, look from when they started till now that albumin level has gone up by a certain amount. I think this is someone who actually I do feel comfortable that they’re doing well. And alternatively, maybe it’s someone who’s on ruxolitinib whose albumin level continues to decline. And you may say, think, you may think, hey, this is maybe symbolic of a treatment that may not be doing enough right now.

Lisa Hatfield:

Okay. Thank you. And do you have an [ACT]IVATION tip for that question? 

Dr. Andrew Kuykendall:

I think my [ACT]IVATION tip for this one is monitor your lab work. Use everything at your fingertips to kind of get a sense for how something’s working. So whether it’s albumin level or spleen size or symptoms. I think the [ACT]IVATION tip here is really take everything into account to know if the treatment’s working for you.

Katherine Banwell:

So, the symptoms of myelofibrosis as well as the side effects of certain medications can vary greatly among patients. 

Dr. Naveen Pemmaraju:

Yeah. 

Katherine Banwell:

Why is it critical for patients to share any issues they may be having with their care team?  

Dr. Naveen Pemmaraju:

Yeah, exactly what you said. So, those two concepts are tied. Since the disease is so rare and it’s so heterogeneous, not just patient to patient, but within the same patient over the journey of years, that is the reason. So, because of that, that’s why one has to communicate every single thing to the healthcare team. It’s interesting. Something that the patient may not believe is serious, the caregiver sometimes knows, right, team?  

So, sometimes the person who’s your loved one or caregiver, “Oh, you know, that’s not-quite-right.” Sometimes the patient knows obviously, and then sometimes the healthcare team may say, “You know, that’s not-quite-right.” I think the not-quite-right thing is the key because that is what supersedes or at least precedes lab testing, X-rays, imaging, and bone marrows, it has to be some provocation. So, what I try to tell people is you know your body best. So, you want to be in touch with yourself, with your body, and anything that isn’t right, don’t be the final judge on that.  

Push it up the chain, let your caregiver know, let your doctors know, let your team know, and let them help you decide. Sometimes it may be nothing, that’s fine. Sometimes it may be something. Sometimes it may be something outside of your MPN. That’s another key theme, I think, I mentioned here a couple of times. Anemia is a good example. So, lowering of the hemoglobin. It’s exactly what you just asked me. So, in addition to looking to see if it’s the disease progression itself, okay, fine.  

However, could it also be drug toxicities, as you mentioned? So, the JAK inhibitor may be causing the anemia or whatever. Then the third bucket is, could it be anemia of regular life stuff, iron deficiency anemia. Could it be a colon cancer or a polyp that’s hiding there? Could it be vitamin B12 deficiency, hemolysis, immune, or something destroying the red blood cells, etc., etc.? So, you make an awesome point, which is all of that can be alleviated or the ball can be started rolling, if you will, by mentioning it. So, the key is no shame, no silence, and mention everything.  

Katherine Banwell:

No silly questions.  

Dr. Naveen Pemmaraju:

No silly questions, that’s right.

Katherine Banwell:

So, once all testing is complete and the patient has an accurate diagnosis, they’ll work with their doctor then on a treatment approach. You’ve touched on this a little bit, but  

What are the types of treatment available for people with myelofibrosis? 

Dr. Naveen Pemmaraju:

Yeah, thanks, Katherine. We’ll keep it general and standard of care. As you mentioned at the top, I’ll reiterate, that none of these are intended to be specific instructions for specific folks. However, in general, for the category of patients with myelofibrosis, in general, there’s not many treatments, unfortunately. As of 2024, we have only four standard JAK inhibitors. So, that’s this pathway we’re talking about, JAK-STAT. Interestingly, you don’t have to be JAK2V617F mutated. These are for the whole pathway.  

So, all patients with myelofibrosis, are intermediate to high risk. The first one, Katherine, is ruxolitinib (Jakafi), which has been around for more than a decade, and first in class JAK inhibitor. The second drug is fedratinib (Inrebic). The third is pacritinib (Vonjo), approved only in 2020 for those patients with less than platelets of 50. Then the myelofibrosis drug, momelotinib (Ojjaara), just approved not even a year ago, in September of 2023 for myelofibrosis with anemia. So, those four are considered as called JAK inhibitors.  

They are really the only targeted therapy class of drugs specifically approved in the MF space. Outside of that, there’s older and other drugs that me and others have used, if you will, so-called off-label or historical use, hydroxyurea  (Hydrea), interferon products such as pegylated interferon. Hypomethylators such as azacitidine (Vidaza) and decitabine (Dacogen), particularly in more advanced cases. Some of those drugs are borrowed from MDS and AML and have been around for decades.  

Then of course, finally, clinical trials. We really recommend folks, if they have the ability and feasibility, clinical trials, even in the first diagnosis setting. So, untreated, first therapy. These clinical trials, Katherine, are based on three factors. One is JAK inhibitor plus another agent. So, that’s kind of like a combination trial. Two is add-on agents. So, you’re already on the JAK inhibitor for a while, maybe it’s starting to not work. Then you add in a third agent.  

Then three is a completely novel agent beyond the JAK-STAT pathway. Then maybe we can even add a fourth one now as this is evolving in real-time, which is anemia-targeting drugs. Many of our patients have either transfusion-dependent or bad anemia. Some of the drugs that are being developed are specifically aimed at them.

Katherine Banwell:

Hello and welcome. I’m your host, Katherine Banwell. Today’s webinar is part of the Patient Empowerment Network’s Elevate Series to help myelofibrosis patients and care partners feel well-informed when making treatment decisions with their healthcare team. On today’s program, an expert will join us to share advice for accessing better overall care. 

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

Dr. Naveen Pemmaraju:

Oh, thanks, Katherine, and to Jamie and the team. I’m Dr. Naveen Pemmaraju, a Professor of Leukemia at MD Anderson Cancer Center in Houston, Texas. I also serve as the director for our rare disease program focusing on BPDCN and, of course, MPNs. Also, I want to mention, I have another hat, which is executive director for MD Anderson Cancer Network for Cancer Medicine. Thanks, Katherine.   

Katherine Banwell:

Well, thank you so much for taking the time out of your day to join us. I’d like to start by discussing your role as a researcher. You’re on the front lines for advancements in the myelofibrosis field. What led you here, and why is it important to you?  

Dr. Naveen Pemmaraju:

Well, I think it’s an important question to start with and one that we need to evaluate and dynamically reevaluate over time. I think really for me, two major themes, Katherine, that brought me to this point. One is the absolute desire to be there for patients who don’t have a voice. So, that means giving voice to the voiceless. It’s something I’ve always been good at ever since I was a youth, which is advocating for those who may not be able to or cannot advocate for themselves.  

So, this is the rare disease thread. A lot of my colleagues were going into lung cancer, breast cancer, and colon cancer, very important. We need folks there. However, those were common diseases, largely elucidated. I was always drawn to the more difficult-to-treat diseases, esoteric, and rare, and I think that’s one component, which is the patient voice.  

The second aspect is scientific interest. Again, in the more common tumor types and diseases, there’s a lot already known. So, many of the researchers and research being done is either derivative from that knowledge, Katherine, a or kind of secondary. I wanted to put my efforts and my team’s efforts and frankly, my life effort into trying to figure out new science, new pathways, new breakthroughs, new ideas, and new concepts. I find that in the rare disease space, that’s where I can do that. So, both from the humanistic patient aspect and the science aspect.  

Katherine Banwell:

Well, it sounds like it’s a challenge to you as well.  

Dr. Naveen Pemmaraju:

I think that’s a great point. So, while it’s intellectually satisfying and very important to pursue this, and I love my patients, the clinic, and my team, you make a really good point. Every day when I wake up, it is the challenge that really drives you, which is to try to improve not only the lives of our patients but the quality of life.  

Try to improve the education barriers, which are many, and then the access barriers, not only here in the U.S., but all over the world. Social media has helped that, democratization of information, and platforms like yours right now to get the message out there to folks who need it the most. However, you make a good point. We have a lot of challenges and a lot of barriers, and that motivates me to get up in the morning every day. 

Katherine Banwell:

When it comes to choosing therapy, Dr. Pemmaraju, it’s important to work with your healthcare team to identify what is going to work best for you. So, as a clinician, how do you define shared decision-making?  

Dr. Naveen Pemmaraju:

Very important. So, shared decision-making to me means a partnership. It means a journey that the patient and the providing team are about to embark on. It’s a very different approach than a one-way, I tell you, you do this. Instead, I see it as a bi-directional exchange of ideas.  

Each visit, each EPIC in-basket or EMR communication, each touch with the healthcare system, the pharmacist, the PA, nurse, whoever is dealing with the patient, I think that’s the key.  

So, a bi-directional exchange of ideas, what’s important to you as the patient? What’s important to the caregiver? What are the worries? What are the barriers? Designing a treatment system around that, a treatment paradigm and approach. Discussing risks, benefits, side effects, toxicities, alternatives, and then a constant dynamic reevaluation throughout. That’s what I pictured. It has to be a journey and a partnership.  

Katherine Banwell:

Well, part of making care decisions is setting goals and I think you’ve just alluded to that. What are treatment goals for myelofibrosis, and how are they determined?  

Dr. Naveen Pemmaraju:

That’s a great question. Myelofibrosis treatment goals are changing in real-time. I would say as of this recording, 2024, the main three things that I want patients to think about and the caregivers.  

Number one is a stem-cell transplant eligible or not? It used to be based on age and comorbidities, but there are other factors. So, are we going to stem cell transplants or not? That determines a lot of the journey. Two is a clinical trial or not. So, are we doing the standard of care therapy, often one pill at a time, or clinical trial, either an IV drug, a pill, or combinations? Then three is that dynamic assessment that we talked about, which is what are the goals of care? Often our patients with myelofibrosis have decreased quality of life, enlarged organs, fatigue, cachexia, and malnutrition.  

These are the central components. A lot of times they’re due to the myelofibrosis itself. So, the treatments may improve that. A lot of times it’s the other comorbidities, other health issues. So, working with the PCP, the primary care provider, and the local team. In my case, many of my patients are referrals, as you know, the local MD team. I think these are the three components, transplant eligibility or not, clinical trial versus standard of care. 

Then once we’ve made a treatment decision, minding toxicities and quality of life.  

Katherine Banwell:

Right, okay. So, you’ve touched upon the factors that are considered when choosing therapy for myelofibrosis. Let’s talk about test results. What sort of tests should be done following a myelofibrosis diagnosis?   

Dr. Naveen Pemmaraju:

Well, I think this is something that’s an active area of evolution. I think the good news is I can give you a few standard items. I think most, if not all, of our patients, will require a bone marrow biopsy to be done at baseline and possibly even later on to assess the status of the therapy. Now, in some cases, that may not be available or accessible due to patient preference or comorbidities.  

However, a bone marrow biopsy is a way to look inside and see how the bone marrow tissues are doing. Outside of that, for the blood tests, the two most critical sets are what we call a CBC and a CMP. So, CBC complete blood count. This is where you get your hemoglobin, platelets, and white blood cell count, very important to know at baseline and dynamically.  

Then the complete metabolic profile is very important, Katherine because we need to know how the potassium, kidney function, and liver function are doing. Then finally, I would also say you’ll see your provider add in other blood tests over time, depending on the particular case. Thyroid testing if it’s needed in the case of fatigue, just to name one example. So, I think these are the main categories.  

I think what’s also interesting over time is that this is an issue with us as well in the MPN clinic. You end up seeing your MPN provider and team so much that it’s easy to forget and lose sight of the primary care items too. So, this is a good time to remind folks to stay in touch with their MPN team, the provider, and their caregiver, whether it’s colonoscopies, mammogram, or prostate. I remember over the COVID pandemic time, especially, a lot of that was either sacrificed, forgotten, or on purpose put aside. So, let’s remind people in 2024 to remember to have that partnership as well.  

Katherine Banwell:

How does molecular testing affect treatment options and prognosis? 

Dr. Naveen Pemmaraju:

Right, yeah, I haven’t mentioned that yet because that’s something that we’re trying to layer into. I do find that to be the standard of care now in the treatment of myelofibrosis. What you’re asking about is very important. So, outside of the normal labs in bone marrow morphology, seeing what it looks like under the microscope, we’re starting to add three or four items. One is called cytogenetics, that’s chromosomes. You’re born with 46, so 23 from mother, 23 from father, for example, 46 total.   

Even though most people are not born with an MPN per se, those chromosomes can change and become abnormal over time. So, we want to know that, and that can help us tell low versus high versus intermediate risk. Two is the molecular test you ask about. Most people have heard of JAK2, that’s the most common out of myelofibrosis, maybe 50 percent to 60 percent of cases, JAK2V617F. However, did you know there’s also CALR, which is the second most common molecular mutation, and then MPL. 

Those three are the big three driver mutations. They make up roughly about 90 percent of our cases, 10% being so-called triple-negative. So, you’re negative for all three. When you do deeper sequencing, which is available now clinically, and we check that here, you will find almost always, some other mutation, ASXL1, EZH2, SRSF2, etc. It becomes an alphabet soup very quickly. However, I think basically you should know that there’s JAK2, CALR-MPL, the big three driver mutations, and additional molecular mutations.  

So, therefore we and others believe you should check these as standard. Finally, there’s also flow cytometry. Just want to give a shout-out to that. Most people haven’t heard of that. When you send your bone marrow for testing, in addition to the pathologist looking under the microscope with the human eyes, there’s also a test that does side scatter of light called flow cytometry. That helps to look at a deeper level, maybe the thousandth, maybe even down to the millionth level, what these cancer cells do.  

Katherine Banwell:

What sorts of questions should patients be asking about test results?  

Dr. Naveen Pemmaraju:

I think the number one and number two questions that I advocate for patients or on programs like this, I think the one question that may help a lot is this question of when you hear all the data and ask the question, “Hey, is there any other questions I should be asking that I’m missing?” It’s an interesting question, right? It’s almost a meta, right, kind of a situation. However, when you ask that, every time I’ve been asked in the clinic, it makes me pause and say, “Now that you mentioned it, X, Y, and Z.”  

So, I think it’s a good one to ask either your physician or whoever healthcare provider is in the room, again, nurse, or PA. It’s an interesting one, right? It kind of makes someone maybe even put themselves in your shoes. So, I like it as a device to make people pause in a busy clinic. Yeah, the second question that I think is a good one is to say, “While things are going well right now, I wanted to ask you, doc, what are some things that could happen in the next six months, one year, or two years, adverse events or abnormal things, and is there something I can do to plan for it?” 

Again, it may be somewhat of a theoretical question. The doctor may say, “Okay, right now things are going well,” but it kind of makes people think about contingency plans, and alternative things. Well, now that you mention it, there is this one side effect of this drug. I don’t know, I think those are two kinds of go-to questions that I want people to be equipped with.   

Katherine Banwell:

Yeah, that’s great advice. I’d like to add that if you, the viewer, are interested in learning more about myelofibrosis testing and treatment, PEN has a number of resources available to you. You can find these at powerfulpatients.org/MPN or by scanning the QR code on your screen.  

So, once all testing is complete and the patient has an accurate diagnosis, they’ll work with their doctor then on a treatment approach. You’ve touched on this a little bit, but  

What are the types of treatment available for people with myelofibrosis?  

Dr. Naveen Pemmaraju:

Yeah, thanks, Katherine. We’ll keep it general and standard of care. As you mentioned at the top, I’ll reiterate, that none of these are intended to be specific instructions for specific folks. However, in general, for the category of patients with myelofibrosis, in general, there’s not many treatments, unfortunately. As of 2024, we have only four standard JAK inhibitors. So, that’s this pathway we’re talking about, JAK-STAT. Interestingly, you don’t have to be JAK2V617F mutated. These are for the whole pathway.  

So, all patients with myelofibrosis, are intermediate to high risk. The first one, Katherine, is ruxolitinib (Jakafi), which has been around for more than a decade, and first in class JAK inhibitor. The second drug is fedratinib (Inrebic). The third is pacritinib (Vonjo), approved only in 2020 for those patients with less than platelets of 50. Then the myelofibrosis drug, momelotinib (Ojjaara), just approved not even a year ago, in September of 2023 for myelofibrosis with anemia. So, those four are considered as called JAK inhibitors.   

They are really the only targeted therapy class of drugs specifically approved in the MF space. Outside of that, there’s older and other drugs that me and others have used, if you will, so-called off-label or historical use, hydroxyurea  (Hydrea), interferon products such as pegylated interferon. Hypomethylators such as azacitidine (Vidaza) and decitabine (Dacogen), particularly in more advanced cases. Some of those drugs are borrowed from MDS and AML and have been around for decades.  

Then of course, finally, clinical trials. We really recommend folks, if they have the ability and feasibility, clinical trials, even in the first diagnosis setting. So, untreated, first therapy. These clinical trials, Katherine, are based on three factors. One is JAK inhibitor plus another agent. So, that’s kind of like a combination trial. Two is add-on agents. So, you’re already on the JAK inhibitor for a while, maybe it’s starting to not work. Then you add in a third agent.  

Then three is a completely novel agent beyond the JAK-STAT pathway. Then maybe we can even add a fourth one now as this is evolving in real-time, which is anemia-targeting drugs. Many of our patients have either transfusion-dependent or bad anemia. Some of the drugs that are being developed are specifically aimed at them.  

Katherine Banwell:

There are a couple of new and emerging treatments as well, right? What are those?  

Dr. Naveen Pemmaraju:

Yeah, so right. So, I’m proud to report to the viewers that just now in real time, just in the last year, really we have had several major developments. Now these are not yet FDA-approved agents. They’re experimental investigational agents, but they’ve reached what’s called Phase II or Phase III testing which are the later stages of testing. I’d like to highlight four or five of those.  

These are mostly in the combination space. So, this is a JAK inhibitor plus the new agent. One is called navitoclax. That’s a BCLXL inhibitor, not yet FDA-approved for any indication. However, this has been shown to have activity in the Phase I and II trials, either as a single agent or in combination.  

Now that’s reached Phase III testing. The second one is the pelabresib agent, which is a bromodomain or BET inhibitor. A third, if you can believe it, it’s selinexor (Xpovio), which is an XPO1 inhibitor. Also, a fourth really now entering into Phase III trials is the MDM2 inhibitor navtemadlin. You have these four drugs, which are either completing or starting Phase III, which is the most advanced testing.  

That means they’re randomized trials, usually international trials, many hundreds of patients. It’s an amazing effort that’s unprecedented. By the way, these are being tested in the frontline setting before patients have ever had a JAK inhibitor in combination with. Beyond that, Katherine, there’s many, many trials with novel agents by themselves. So, imetelstat (Rytelo) comes to mind, which is a telomerase inhibitor, for example, which is also in Phase III testing in the relapse setting. So, you’ve already had a JAK inhibitor, it didn’t work out for you. Interestingly in that trial, the overall survival is the primary endpoint rather than spleen and symptoms, which marks the first time we’ve ever seen that. 

It also marks the understanding that these chronic diseases, chronic myelofibrosis can then turn into a more advanced acute in the relapse setting. So, that’s just a sample of some of the ones that are now entering the late stages of trials, many more in Phase I and II. In a good way, there’s a new trial opening once a week.  

Katherine Banwell:

That’s exciting news. So, the symptoms of myelofibrosis as well as the side effects of certain medications can vary greatly among patients. 

Dr. Naveen Pemmaraju:

Yeah. 

Katherine Banwell:

Why is it critical for patients to share any issues they may be having with their care team?  

Dr. Naveen Pemmaraju:

Yeah, exactly what you said. So, those two concepts are tied. Since the disease is so rare and it’s so heterogeneous, not just patient to patient, but within the same patient over the journey of years, that is the reason. So, because of that, that’s why one has to communicate every single thing to the healthcare team. It’s interesting. Something that the patient may not believe is serious, the caregiver sometimes knows, right, team?  

So, sometimes the person who’s your loved one or caregiver, “Oh, you know, that’s not-quite-right.” Sometimes the patient knows obviously, and then sometimes the healthcare team may say, “You know, that’s not-quite-right.” I think the not-quite-right thing is the key because that is what supersedes or at least precedes lab testing, X-rays, imaging, and bone marrows, it has to be some provocation. So, what I try to tell people is you know your body best. So, you want to be in touch with yourself, with your body, and anything that isn’t right, don’t be the final judge on that.  

Push it up the chain, let your caregiver know, let your doctors know, let your team know, and let them help you decide. Sometimes it may be nothing, that’s fine. Sometimes it may be something. Sometimes it may be something outside of your MPN. That’s another key theme, I think, I mentioned here a couple of times. Anemia is a good example. So, lowering of the hemoglobin. It’s exactly what you just asked me. So, in addition to looking to see if it’s the disease progression itself, okay, fine.  

However, could it also be drug toxicities, as you mentioned? So, the JAK inhibitor may be causing the anemia or whatever. Then the third bucket is, could it be anemia of regular life stuff, iron deficiency anemia. Could it be a colon cancer or a polyp that’s hiding there? Could it be vitamin B12 deficiency, hemolysis, immune, or something destroying the red blood cells, etc., etc.? So, you make an awesome point, which is all of that can be alleviated or the ball can be started rolling, if you will, by mentioning it. So, the key is no shame, no silence, and mention everything.  

Katherine Banwell:

No silly questions.  

Dr. Naveen Pemmaraju:

No silly questions, that’s right.  

Katherine Banwell:

Right. I’d like to get to a few audience questions that we received prior to the program.  

Dr. Naveen Pemmaraju:

Sure. 

Katherine Banwell:

Cliff wrote in with this question. “Can you explain the dynamic international prognostic scoring system or DIPSS?” Thank goodness there’s an acronym for that.  

Dr. Naveen Pemmaraju:

Yeah, no, it’s a great question, scoring systems, right?  

Katherine Banwell:

Yeah, and Cliff wants to know how he can ask his doctor about it.  

Katherine Banwell:

Right, so the easiest way to talk about it, the good news is everything we’ve been talking about is incorporated in the scoring system. So, said in another way, we’ve been talking about it subjectively, the scoring systems try to make the subject objective. So, quick history, these started in 2009 with the IPSS, International Prognostic Scoring System. The concept there were a thousand patients in Europe and basically trying to observe the natural history of the progression of myelofibrosis. This was just before, just as the JAK inhibitor era was starting. What we found is that the four groups nicely separate.  

So, the lowest of the low-risk group potentially can be measured in decades for overall survival. Intermediate one, intermediate two, and high risk, again, all separated by overall survival and AML leukemia transformation risk. Now, that’s evolved over time as the questioner is asking for more sophisticated scoring systems. So, that’s all you need to know. So, DIPSS Plus just means Dynamic International Prognostic Scoring System.  

Then there’s DIPSS plus, and can you believe it? There’s even the MIPSS now, the Molecular International Prognostic Scoring System. All right. So, at least there’s a rhyme and reason there. I think each iteration is telling you that we are dynamically understanding more about the disease. Two, the IPSS, the original one, was meant to be only at diagnosis, and the DIPSS by definition, dynamic scoring, is any time during the course of the disease, that’s interesting. Then three, they’re incorporating new factors each time.  

So, from the time of the IPSS to the DIPSS and now the MIPSS, you’re incorporating all these factors that we couldn’t before. Cytogenetics, molecular findings, anemia, transfusion, burn, thrombocytopenia, etc. So, that’s basically it. You can ask your doctor. I mean, basically, in the course of what we do in the non-clinical trial standard of care, even if somebody doesn’t hand stop and calculate these risk scores, we’re talking about the same thing, right? The subjective or the objective matchup.  

However, of interest to the patients, there are calculators that are available, you know, obviously rather than doing it in isolation in your house. Yes, it is better, I agree to do it with your doctor, with your provider team, and see what it means for you. The goal of these is twofold. In clinical trials to help stratify patients so you can understand who’s high risk versus lower. However, in the standard of care, sure it may help with transplant decisions, referrals for clinical trials, etc.  

Katherine Banwell:

Okay. All right, this next question comes from Joel. “I understand that mutational testing should be done at diagnosis. Is there a point where there would be a need to repeat this test?”  

Dr. Naveen Pemmaraju:

Oh, that’s an awesome question. So, we were mentioning that earlier. I do believe and I advocate that all patients should have molecular testing, particularly now as it’s more available widely before it wasn’t. Again, we level set what we’re talking about. In myelofibrosis, three common driver mutations, JAK2, CALR, MPL makes up about 90 percent. 

Then in addition to that, there’s the triple-negative, and you usually find an additional mutation. Then on top of these big three, it’s common to have co-mutations, ASXL1, etc. What we found in this MIPSS score that we just mentioned ties into that. We found now that for the first time, we can incorporate these molecular findings to prognosticate for the patients. That’s why it’s important to check them. So, to this question by Joel, yes, if you have access and availability, not only checking it at baseline but later on at a provoking event.  

So, at the time of relapse, progression, going onto a clinical trial, just to name three of several. I think it’s a good idea to recheck the molecular status. The problem and barriers are what you would expect, cost, expense, access, availability, justification, etc., etc. So, it’s not a mandatory part of the field, especially in the standard of care, non-research aspect. However, if we can get to the point where we can do that, it would be nice and helpful because these mutations change, they’re dynamic.  

You can have negative for mutation  at baseline, positive, and even vice versa, depending on therapies. Are you goimg to go for a transplant? Are you going to go to a clinical trial? Are you changing therapy? It would be nice to know.  

Katherine Banwell:

Right. All right, here’s one more from Diana. “Can diet play a role in either manifesting the disease and or helping with healing? Also, how important is exercise to the healing?”  

Dr. Naveen Pemmaraju:

I give a lot of credit to this area, to my colleagues, Ruben Mesa, Dr. Angela Fleischman, and Dr. Robyn Scherber. A lot of data that’s come out of these groups, which has shown two major findings in our MPN patients of potential clinical significance. One is as the questioner is asking about diet. It is true that we’re, several studies are pointing towards the anti-inflammatory Mediterranean diet as a potential benefit to our patients with MPN. Lots of different ideas there when they measure cytokines. 

These abnormal protein signatures that are in MPN patients can cause fatigue and some of the bad quality of life can be dramatically improved in some cases by following a strict Mediterranean diet over weeks and months. So, that’s something important. People should check it out. Obviously, diets have to be addressed with each patient and each provider because sometimes a diet may work for someone and not for you because of comorbidities, vitamin deficiencies, electrolytes, etc.  

Then the second aspect, if I may include in this question, is also the concept of yoga/meditation. Dr. Ruben Mesa and others have shown, the same thing, that you can have a potential downregulation of some of these abnormal cytokines. However, the caveat is it must be done right with a guided trainer in a real program over a certain period of time. What I think both of these non-pharmacological interventions tell us is that there are things beyond medicines and pills that may really help our patients in some aspect of the disease.  

Well, if that aspect is fatigue, night sweats, headaches, I think that’s a really important thing. So, let’s say together on this program that these data sets are evolving, they’re interesting, they’re intriguing. For some people, it may be an easy incorporation. Frankly, some people may already be doing these things, but as you ask nicely, let’s include in the discussion non-pharmacologic as we heavily investigate the pharmacologic as well. We’re all open to that. Let’s see the data, and the data is evolving.  

Katherine Banwell:

Yeah, absolutely. Well, those were all great questions from our viewers. We ask that you continue to send them to question@powerfulpatients.org, and we will work to get them answered on future programs. I’d like to turn back to self-advocacy for a moment, Dr. Pemmaraju. Managing the worry associated with a diagnosis or concerns about the future, and we did touch upon that earlier, it can lead to anxiety and fear. Why is it important for patients to share any worries they may be having with their care team?  

Dr. Naveen Pemmaraju:

Well, I love this question. It really wraps up everything we’re talking about here. I believe that part of the journey for the patient does include mental and psychological safety. So, it’s very difficult to make major life decisions when one is not feeling mentally, or psychologically safe. So, that’s what you’re hitting on here. Anxiety, fear, and worry, of course, are a natural and important part of the patient journey with any cancer, much less a rare cancer and blood cancer on top of that. However, sometimes in some patients, it can become so paralyzing, so overtaking, and overwhelming that it may prevent the ability of the patient to receive information, process it, and then make a decision back. Yes, we want people to have caregivers, and power of attorney, all those things are essential, but we also want people to have their own agency in aegis.   

So, I would approach this from three aspects. I really love this question because I don’t think we were addressing it head-on 10 or 15 years ago. One aspect is the disease itself. These MPNs, systemic mastocytosis, eosinophilia, myelofibrosis, PV, ET, all of these MPNs can secrete these cytokines and granules that can mess up the patient’s mindset, even just profound fatigue leading to a slowing down of the neurological process. So, I think underlying control of the disease is something that can affect this. Number two is the side effects from some of these medicines. Interferon is a great example, a wonderful class of drugs that’s been around for decades, treated for solid and liquid tumors, but it has a known side effect of causing brain fog. Some of these issues can even cause depression and anxiety in some people. So, education, mitigation, following these things with dose reduction, that’s an important part.  

A third aspect, Katherine, is actually looking with a counselor and a therapist on the spectrum of this. So, normal, adjustment disorder, depression, for example. What we’ve had as a breakthrough at our center has been the supportive palliative care team. They’ve been phenomenal. So, this is a group of doctors who’s kind of one-third internist, one-third oncologist, and one-third psychiatry support.   

So, rather than the usual consults that we used to do either to psychiatry or to social work case managers, there is this burgeoning field of supportive care medicine which has revolutionized the care, I think, particularly for solid tumor patients and now hopefully for our blood cancer patients. So, I’m able to refer patients for a variety of reasons. There’s a fatigue clinic for overwhelming fatigue. There is obviously depression, and anxiety support, either with medications, talk therapy, or both. Smoking secession for folks who are still smoking and maybe either withdrawing or quitting is causing stress.   

So, it’s a really cool science and if your center has that, that’s something to inquire about. Then lastly, as we mentioned, a nice running theme today, Katherine, is looking for other medical stuff outside of the MPN. I mentioned thyroid earlier. Remember, you have a thyroid abnormality that can cause fatigue, depression, and anxiety, right? So, what’s your TSH thyroid function, and vitamin deficiencies?  

Screening for your other well-person screening exams, looking for solid tumors, looking for other conditions that may be mimicking the MPN, or mimicking one of your other aspects. So, again, it comes down to partnership with the primary care team and looking at that. So, I think those are some of the aspects that I want to mention, but it’s such an important part of the journey. I really have to mention that as well.  

Katherine Banwell:

Financial concerns may weigh heavy on patients and families. While everyone’s situation is different, do you have advice for where patients can turn for financial support?  

Dr. Naveen Pemmaraju:

I think this is going to be the next great revolution. Just like I mentioned, the psychiatry, mood, and quality of life realm, I think this will be the next one of the next decade. I think largely it has been not even overlooked, just misunderstood. I’m an academic. I’ve been an academic my whole life, so I’ve never practiced in a private practice. So, some of these issues are quite difficult and foreign for many of us academic doctors.  

In the community setting, there’s a whole set of pressures. Then of course, as you mentioned, there is a whole theme of the pharmaceutical companies helping. In the case of the JAK inhibitors, many of them have patient assistance programs, which have been vital to our patients. So, I think that financial toxicity, that’s what you’re asking about, right, is going to be the next era, the next realm, has been severely underlooked at, really misunderstood.  

You know, I think at the academic centers, you know, obviously we have access to financial counselors, business office, those folks are invaluable. I see them as an essential part of our team, particularly on patients who are trying to get on clinical trials, etc. I think in the community aspect where many of our patients are treated, I think there’s going to be a challenge. So, we have to work with insurance companies, pharmaceuticals, local clinics.  

For patients who don’t have healthcare insurance, try to get them insurance, county systems, cache safety net systems. However, I think you hit on it. I think this will be a new vital sign. It’ll be a new toxicity. It’ll be a new aspect when we consider new drug approvals, and financial toxicity. 

Katherine Banwell:

As we close the program, Dr. Pemmaraju, what would you like to leave the audience with? Why are you hopeful about the future of myelofibrosis care and treatment?  

Dr. Naveen Pemmaraju:

You know, I am hopeful. I am very hopeful. I think the two biggest things that I’m excited about for our patients and their caregivers are one, the burgeoning clinical trial portfolio that we have all over the world.  

Very excited to see the interconnections from Asia, Europe, North and South America. We’re trying to make inroads into Africa and Australia as well. So, a true worldwide  effort for MPNs, particularly myelofibrosis and clinical trials. So, stay tuned for that. I think that’s an exciting aspect.  So, not just the existence of them, but the interconnectivity,  communication, improvement, and availability. I think the second aspect that I’m super excited about is the democratization of information.  

Honestly, 10 years ago, it was kind of difficult to find out information about these diseases, not 100 years ago, just 10 years ago. I really attribute social media and the interconnectivity of folks on these platforms to getting information out there. I would put this type of a platform as well in that same conversation, which is newsflash, nobody’s reading books anymore. Okay, there I said it. 

However, people do have time for a quick two or three-minute blurb while they’re in the coffee line. So, if they can watch a snippet of an interview like this. They can get an email blast about a community town hall. They can get a paragraph on the new drug that just came out. People can take in information in small amounts so I think we have to meet folks, Katherine, where they are.  

We cannot expect people to go to the library and open up a dusty book. I mean, that was in my generation 30 years ago. So, people are on their phones, let’s meet them on their phones. They’re online let’s meet them there. If you’re going to have an in-person town hall, make it high-yield, make it worth somebody’s time and energy and effort frankly, to leave their house to come. Finally, let’s make things affordable from an educational standpoint, if not free, to get the information to the people who need it the most. I’m hopeful about that. I think social media and online platforms have helped us with that.  

Katherine Banwell:

Yeah. Well, that’s great advice, Dr. Pemmaraju. I want to thank you for joining us today. It’s been a pleasure speaking with you.  

Dr. Naveen Pemmaraju:

Thank you so much, Katherine, to the team. I love doing these with you, and thanks for doing this good work.

Lisa Hatfield:

Dr. Grunwald, can you discuss novel therapies and current clinical trials for lower risk and higher risk myelofibrosis?

Dr. Michael Grunwald:

We’re in an exciting time in myelofibrosis because we’ve already had some new therapies introduced into the clinic in recent years and there are a number of ongoing trials that are very exciting. Some of these trials look at agents in combination with JAK inhibitors or four currently approved JAK inhibitors for myelofibrosis, ruxolitinib (Jakafi) being the oldest one. And many of these trials that are ongoing will combine a novel agent.

So there’s pelabresib (CPI-0610), which is from a class of medicines called BET inhibitors, which has shown very good efficacy in reducing spleen size when it’s combined with ruxolitinib in the treatment of newly diagnosed patients with myelofibrosis. We also have navitoclax, which is an apoptosis inhibitor or a cell death inhibitor that’s been used in combination with ruxolitinib (Jakafi) and has had promising results presented in terms of spleen reduction. There’s selinexor (Xpovio), which is a drug approved for another blood disease, multiple myeloma, and that’s being combined in trials with ruxolitinib.

And then navtemadlin as well, which is from a group of drugs called MDM2 inhibitors. Then we have drugs being looked at as a single agent. So there’s an agent called imetelstat (Rytelo) that was recently approved for a cousin of myelofibrosis called myelodysplastic syndrome or MDS, and now it’s being evaluated in myelofibrosis.

We have ropeginterferon alfa-2b (Besremi), which is approved for another MPN polycythemia vera and it’s being looked at in myelofibrosis as well. Something really exciting to me is the CALR mutant inhibitors. So many patients with myelofibrosis will have CALR mutations. Probably around 30 percent of myelofibrosis patients have that mutation. And there are some strategies being developed to try to target that mutation and kill myelofibrosis cells by targeting it. There’s a naked antibody that’s in clinical trials. There is something called a bispecific antibody that is targeting the mutation, but also trying to bring immune cells or T cells close to the tumor cells so that there’s good tumor killing by the immune system.

And finally there’s a vaccine in development to try to target this mutation. There’s also a medicine called bomedemstat (MK-3543) that’s being tested in multiple myeloproliferative neoplasms and it’s been looked at as a single agent, and I believe it’s going to be looked at as a combination with a JAK inhibitor as well. Most of those therapies are targeting intermediate and high risk MF patients. That’s where a lot of the clinical trial action is. The ropeginterferon alfa-2b study is looking at lower risk patients. And then, there are some strategies to try to improve anemia in myelofibrosis, and those strategies can also include some patients toward the lower end of the risk spectrum.

For example, there’s a drug that’s been approved for myelodysplastic syndrome to help anemia since 2019, I think it’s been, 2019 or 2020. And that’s luspatercept (Reblozyl) it’s being tested for anemia in myelofibrosis. And I think that might be a drug that would be appropriate for some patients with lower risk disease who happen to have some anemia. My [ACT]IVATION tip for this question is that it is okay and, in fact, encouraged for patients to ask about clinical trials, especially if patients have access to a clinical trial center where they might be able to be treated on a clinical trial.

Katherine:

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

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

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

Dr. Hobbs:

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

Katherine:

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

Dr. Hobbs:

My pleasure.  

Katherine:

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

Dr. Hobbs:

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

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

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

Katherine:

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

Dr. Hobbs:

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

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

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

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

Katherine:

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

Dr. Hobbs:

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

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

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

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

Katherine:

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

Dr. Hobbs:

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

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

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

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

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

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

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

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

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

Katherine:

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

Dr. Hobbs:

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

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

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

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

Katherine:

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

Dr. Hobbs:

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

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

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

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

Katherine:

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

Dr. Hobbs:

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

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

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

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

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

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

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

Katherine:

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

Dr. Hobbs:

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

Katherine:

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

Dr. Hobbs:

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

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

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

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

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

Katherine:

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

Dr. Hobbs:

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

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

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

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

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

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

Katherine:

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

Dr. Hobbs:

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

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

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

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

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

Katherine:

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

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

Dr. Hobbs:

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

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

Katherine:

Well, thank you so much for taking time to join us today, Dr. Hobbs, we really appreciate it.  

Dr. Hobbs:

Sure, it’s always a pleasure.

Katherine Banwell:

Dr. Masarova, molecular testing is important for people diagnosed with MPNs and may help provide insight into effective treatment approaches. What are some new areas of research related to molecular markers? 

Dr. Lucia Masarova:

Molecular markers are very relevant in our designs or thinking about myeloproliferative neoplasms. Not only treatments, but also the disease qualification or prognostication wherever since the discovery of the so-called driver mutations, which are the mutations responsible for the overproduction of the blood counts and disease pathogenesis.  

Among them we have the most common, JAK2 mutation, then also calreticulin, MPL, or in some instances we don’t even understand and call it triple-negative. 

There we have learned, over the years, that the amount of the expression, or allele burden, does correlate with the disease behavior outcome. And then our ability to reverse that. So, a chief decrease of the burden is also relevant to the outcome of the patients. So, developing therapies or even putting these as an endpoint for clinical trials is important for our decision-making and moving towards eradication of the disease.  

Then there are additional molecular changes, which include non-drivers, which are additional mutations that we have learned and even implemented in the latest prognostic models, some of them are very unfavorable, such as ASXL1, Ezh2, IDH mutations, certain splicing factors.  

And those play additional roles, a lot of it we still do not understand, in how the disease is going to ultimately behave. What is their interplay, and how we can interfere with that?  

So, learning about the impact of these mutations and the drivers and the other effects that cause the disease evolution will probably become the landmark of this decade and in facing myeloproliferative neoplasms. 

And I’m hoping we will develop medications, or we will be able to focus our efforts and our decision-making based on molecular definition, as it’s currently very broadly seen across all cancers. We call it precision medicine where we really define, “How does this look like,” not how we box it in based on morphology. What is it driving? What is it not responding? And what can we do to improve that?  

So, I totally see here a big potent and powerful tool to allow us to make the most individualized and customized decisions for our patients to offer them the best outcomes.

Transcript:

Katherine Banwell:

Dr. Masarova, you are a coauthor in an article entitled Moving Towards Disease Modification in Polycythemia Vera, which was recently published in the journal Blood. Can you share some of the highlights of the article and what it means for PV patients? 

Dr. Lucia Masarova:

Disease modification in polycythemia vera. I’m so excited finally being talking about this because we’ve been really, really, really so hungry for this term, although we still don’t know what it means.  

So, we group together with lots of experts in the myeloproliferative neoplasm field and try to brainstorm and put together, “What does it actually mean?” And to me, and to all of us, it was to offer our patients the normal or not-normal lifespan without the consequences of the disease that they face. Because we historically divided polycythemia vera into high-risk or low-risk disease based on the age or previous history of thrombosis or clotting complications.  

However, there is a huge area of patients that wouldn’t have either, and still suffer tremendously a bad quality of life, and ultimately also face the disease progression to myelofibrosis, which is the most actual complication of long-term polycythemia vera duration.  

So, the concept of disease modification would be to actually prevent the complications to even occur. To allow our patient to live free of having the fear of living with a thrombosis or clotting complication or ultimately progress into myelofibrosis. We have to learn how to get there. What are the relevant endpoints of tools for us to utilize to really understand? We have learned a lot from seeing what we call molecular remissions, or control of the JAK2 mutation with certain medications, for example, interferons or latest ruxolitinib (Jakafi), the JAK inhibition, where the decrease of the allele burden, which represents the disease, is correlated with better outcome.  

So, that is something that we have to be learning down the road with a longer follow-up. But that basically triggered us to focus on what can we do better? How do we prevent this from even happening rather than only controlling the historically main points of the disease which are presented by the blood counts symptoms and display? And where we are actually failing quite a lot of patients because despite them having a control count, they still don’t have a happy life, and lots of them suffer and complain.  

So, this is something to be learned, and this is opening the disease modification not only for polycythemia vera, but also for all patients with myeloproliferative neoplasms, which have a little bit of a different feeling in the whole myeloid malignancies field. Because it is a very long disease, and it could evolve and change, and only now we starting to understand what does actually happen there. Why some people could live for 30 years, and never face any consequences, and the others would progress very fast? 

So, disease modification would normally allow us to develop and learn more tools and better biomarkers, but also focus on drugs that are really needed to help with these long-term outcomes of our patients.

Transcript:

Katherine Banwell:

Dr. Masarova, you were in New York recently for the MPN congress. Can you share some highlights from that meeting? 

Dr. Lucia Masarova:

Yeah. Sure. That was a very interesting and very loaded conference full of experts and great data. I really liked the overall excellent update of all the therapies that currently exist in the MPN space, including polycythemia vera, essential thrombocythemia, myelofibrosis. So, really a broad breadth of JAK inhibitors, their current sequencing, combinations, interferon update. I very much like also the focus of the novel therapies, which actually talked about, for example, the development of the antibody against mutant calreticulin, PIM inhibitors, and a couple others. They are very promising in the space. 

There were also very, very relevant clinical data. I think I really, really enjoyed the radiation in hematopoiesis topic. It spurred lots of discussions in the room. And also, fantastic talks about clonal hematopoiesis and its role in patients with myeloproliferative neoplasms and cancers.  

Overall, very great data on artificial intelligence because that will be a very needed tool, but also a very worrisome tool, at this point, until you learn how to use it to help our patients. But that showed a very promising effect and ability for us to, for example, predict thrombosis risk in polycythemia vera patients or to distinguish patients with ET versus prefibrotic myelofibrosis, which is still subject to lots of basically subjective analysis from hematopathologist.  

And also, the poster section was quite striking and really excellent. You could walk around and see so many interesting data. The match and direct comparisons of JAK inhibitors, particularly the latest approved, momelotinib (Ojjaara), as it compared to safety data which do currently exist in fedratinib (Inrebic) or pacritinib (Vonjo). 

Katherine Banwell:

When it comes to MPN research and emerging treatment options, what are you excited about specifically? 

Dr. Lucia Masarova:

There is a lot of excitement in the field currently, and it really depends how we put these patients in, as I would call, boxes, but I don’t like the term. We have these less aggressive diseases, such as polycythemia vera and essential thrombocythemia.  

Where I’m really excited about the role of interferon, with the approval of ropeginterferon (Besremi), or ropeginterferon in United States as well as Europe, we have opened a door for learning how can we do better.  

It is approved for polycythemia vera patients. There are currently clinical trials running in essential thrombocythemia patients, within patients with prefibrotic myelofibrosis. That’s an agent that has an ability to go after the disease clone and hopefully, hopefully eradicate or prevent it. Especially, especially exciting in the terms of preventing it for progression.  

Then iron metabolize modifier, hepcidin mimetics, other agents impacting this. It’s very important we finally learn how iron plays the role in these patients and how we can actually improve. Very important area in helping patients requiring phlebotomies and hopefully, hopefully altering the whole disease outcome in the long-term. 

For myelofibrosis we live in an era of JAK inhibitors. We are so excited to have four currently approved and we’re looking forward to the combinations where we have now safer and less cytopenic agents that have a role in anemia or thrombocytopenia and hopefully will be able to be combined with others. 

So, we could even move the field more into other hematologic malignancies, where in myeloma we use five, six, seven, eight drugs. For myelofibrosis, we still have one. So, I think we have still a lot to do. 

And then non-JAK inhibitor combination. Non-JAK inhibitor, a compounds or mechanism of action really tailored to the disease pathogenesis. Calreticulin, excellent topic, which I’m saying maybe in couple years we will be really classifying myeloproliferative neoplasm calreticulin-mutated, but also JAK2-mutated, and we will not be calling them one because hopefully we will find a tool to eradicate calreticulin and to really be able to offer ultimate – what I call ultimate cure.  

So, that’ll be something really exciting to come and all of these investigators in MPN fields are so eager to see what – whether the preclinical data we have seen are going to stand in our patients. And that would be really fantastic.

Thriving With an MPN: Advice for Setting Goals and Making Treatment Decisions

Myeloproliferative Neoplasm News and Research Updates

Transcript:

Katherine Banwell:

When considering treatment options, what key questions should patients ask about their proposed treatment plan? 

Dr. Lucia Masarova:

What’s the goal of my therapy? That is one of the most important things to know. Patients don’t even know how long they have to be on the medicines. What to do and how does it look when the medicine is still working? What do I need to be looking for in this medicine? And then what are we going to do if it fails? And what does it actually mean when it fails? What is the schedule? How burdensome the treatment is? How often do I have to come?  

How often and what do I have to pay? Because the financial burden we have to really, really face the truth. It is very, very, very significant and somebody living with this disease predicates. It’s something we cannot take lightly, and we really have to combine our efforts and help with that. There are fantastic patient support organizations, but is not well-known, and is still in the rare – in rarer field. So, there’s more effort that we do. 

When do I need more help? Where to be referred to more experts? What is the role of stem cell transplantations, if ever? So, those are really the key things.  

Where do I find reliable resources to learn about my treatment, to learn about the disease? How do I connect with people from the same community? It is a disease with a lower age in a lot of circumstances and really facing this disease in the 30s or 40s or 50s is a really challenging thing. Although we have more and more medications currently, we really do have now to start thinking about their durability, about the safety for long-term, about their assessments for not performing, and where do we place the ultimate cure for stem cell transplants?  

And how do we make it actually happen in more and more eligible patients? Because we have to face the truth. It is still not utilized to where it belongs. Patients are not being referred. 

Patients are not being transplanted. And they may change with novel therapies. But we have to really consider all of our tools to offer the longest life span and to prevent all the disease trouble that comes with living with MPNs.   

Katherine Banwell:

When it comes to clinical trials, where do they fit in in choosing treatment? 

Dr. Lucia Masarova:

For me, it’s number one., and always number one.  

That’s just the academic centers which are dedicated and focused on developing better and novel and up front and just tailored and customized drugs. But I know that the life is out there and it’s a little bit more challenging for everybody to deal with such a rare disease.  

I would definitely say any patient that does not respond to current therapy in terms of uncontrolled symptoms or spleen, or other concerns should be referred and evaluated for participation in clinical trials. It is the only way we could understand what is driving that this is not responding and how could we help the best?   

For patients with myelofibrosis, which is the most aggressive myeloproliferative neoplasm, I would definitely put it in. If they are not doing well on number  one, JAK inhibitor, whatever is being used, they should be highly encouraged to be referred to centers and evaluated for clinical trials. 

We have been developing as others and own strategies to potentiate the benefit and efficacy of the current treatments, as well as agents in what we call salvage or refractory setting.  

However, I cannot emphasize enough to really focus on the first track that providers choose for their patients and utilize it to the best ability to avoid frequent or quick switching. Because in a salvage or  refractory setting we cannot offer the same benefit we could offer upfront. We are pushing the disease, maybe being less responsive, maybe more refractory, if we don’t handle the medication we have currently on the table to the best ability.  

Those are excellent medications, fantastic drugs, but there are shortcomings in each and every one of them. And we could do better to really start thinking about what has happened with the medication, why is it failing the patient, and what else could we do? And that’s only possible in the clinical trial setting, especially in such a rare disease as myeloproliferative neoplasms are.   

Katherine Banwell:

Why is it important for patients to feel like they have a voice in their treatment options? 

Dr. Lucia Masarova:

Because it’s about the patients. I would say, as I always say to my patients, “Nobody’s a better advocate for you than you.” I really, really, really like working with patients. They are educated. They understand where to find resources. They’re not afraid to ask. That challenges all of my team and everybody to really be engaged. They know when to notify me. Not to be quiet when they need something. And really raise their voice when something doesn’t work.  

Patients know their bodies more than anybody can. And no data, no boxes, no books can ever tell me how it actually is. It’s not by chance we have two ears to listen and one mouth to talk.  

So, we have to really listen what the patient has to say and take all the abilities, the resources, the knowledge, the capabilities to really make the best thing for the patients, because it is ultimately and only about that.

Katherine Banwell:

Dr. Masarova, stem cell transplant is sometimes recommended for people with myelofibrosis. Is this still the closest option to cure for those patients? 

Dr. Lucia Masarova:

I would say so, as much as we don’t like it. We would like to develop novel conservative, less aggressive, that we call procedures or drugs. Stem cell transplants still represent a long-term cure for patients that are eligible. 

Katherine Banwell:

What about for patients who don’t qualify for stem cell transplant? What are effective long-term treatments for them? 

Dr. Lucia Masarova:

That’s a very, very important question and topic. The key point here is the long-term because long-term is a little difficult term in conservative management of myeloproliferative neoplasm, particularly when it comes to myelofibrosis.  

With the development of JAK inhibitors, the longest experiences we have with the first one called ruxolitinib or Jakafi, we have seen prolonged outcomes in survival so patients could live longer than expected before.  

However, it’s not forever. So, that’s why we are trying to develop novel strategies where I see a lot of roles of combinations of JAK inhibitors and other correlative compounds, such as bromodomains inhibitors or hypomethylating agents or others that would affect the pathways that we are missing currently to cover with the JAK inhibition. And that ultimately leads to medication failures and patients being refractory and then having a shortened lifespan.  

So, I’m hoping we will develop something for long-term. Particularly promising a very, very interesting concept is with the calreticulin where we are developing monoclonal antibodies or vaccines because we have seen and discovered calreticulin driver to be a targetable thing that causes immunogenicity. 

But I do really hope that we will move forward with these discoveries and the JAK mutate or other drivers causing myeloproliferative neoplasms to offer long-term management.
