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.

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.

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.

Transcript:

Lisa Hatfield:

According to the National Library of Medicine, less than 300 genetic tests were available in the 1990s; at the end of 2012, almost 3,000 genetic tests were available and now in 2023, +76,000 tests are available to the general public. Some of those genetic tests can be used on MPN patients through telegenetic consultations. These are appointments done via telemedicine with genetic counselors to determine what gene mutations you might have. They can be done by telephone or video conferencing. 

As you would imagine, this type of telemedicine became more common during the COVID-19 pandemic and should still remain in a patient’s tool box post-pandemic. While telegenetics consultations play an important role in a patient’s personalized care by determining if there are genetic mutations like JAK2 or MPL, the added benefit is that these online consultations protect the patient from exposure to viruses and potential infections as well as saves them valuable time, energy, and travel costs.

Telegenetic consultations are also beneficial for remote patients, including those in rural areas with limited or no access to genetic services. Be sure to talk to your doctor to see if you can benefit from telegenetic consults. This can be especially important or helpful to do at the beginning of your MPN journey or before switching treatments.

Dr. Palmer:

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

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

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

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

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

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

Lisa Hatfield:

Thanks for that.

Dr. Palmer:

If that makes…yeah.

Lisa Hatfield:

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

Dr. Palmer:

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

How useful is having a genetic panel done? Should all patients get molecular or genetic testing? 

Dr. Hobbs:

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

And genetic testing involves more than just testing the JAK2 mutation. So, we know that the JAK2 mutation is the most common mutation in patients with MPN. But that being said, there are other mutations that also occur such as the calreticulin mutation and the MPL mutation.   

And so, I think having genetic testing that at least tests for those three mutations is very important so that we can actually help a patient know that they have an MPN. In addition to those three main mutations, many clinicians now have access to what’s called extended next-generation sequencing, where there’s a panel that tests for many different genes at the same time and can test for a variety of other mutations.  

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

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

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

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

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

Katherine:

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

Dr. Hobbs:

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

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

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

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

Katherine:

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

Dr. Hobbs:

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

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

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

Dr. Kristen Pettit:

Next generation sequencing or NGS refers to tests done from the blood or the bone marrow that can look for many different genetic mutations at once. So we know that most patients with MPNs will have mutations in either JAK2, CALR, or MPL but many will also have additional genetic mutations.

These additional genetic mutations may be important prognostically as we know is, we know some of these additional genetic mutations can confer either higher or lower risk of the disease progressing over time. So, I think next generation sequencing or NGS panels should be a part of the work up for most patients with MPNs at the time of initial diagnosis, and probably again, at the time that there’s any concern for disease progression in the future.

My personal philosophy is I view myself and my interactions with patients as a partnership. And I have and I bring to this partnership medical knowledge, some scientific knowledge, experience treating patients, understanding the diseases and the biology of the diseases. 

What patients bring is their personal histories, what they want and need from therapy, what their expectations are, where their fears and concerns might be. And as we share our information, I think that provides the opportunity to come to an understanding where the patient can make an informed decision and I can support that decision, that we know what the groundwork has been between us. And so, I spend, often, a lot of time in the beginning with patients kind of trying to understand who they are as people and what they need and expect. And everybody, as you might imagine, is an individual.  

And I present to them the information, and I try to encourage questions so that I know that they understand the information that I’m giving so that they can make a decision in their best interest. And so, I think shared decision-making is the only model I practice.  

Now, patients have different needs, particularly some of my older patients. And, culturally, there are some differences where they don’t want to take that role of being the decision-maker. And so, then my role changes a little bit, and it becomes more to make sure they’re comfortable and understand the direction that we’re going in and, again, always trying to encourage people to take ownership. 

I think, in New York City, that’s not so common. People are pretty well-informed and interested and more than willing to express their opinions.  

And so, I would say it can be very rewarding to come to a decision where patients feel their needs are being met.

Katherine Banwell:

Dr. Scandura, you mentioned promising research in myelofibrosis treatment. What are you most excited about right now? 

Dr. Scandura:

I think there are a couple drugs that have been in clinical trials that have had activity in a significant subset. So, anywhere from 20 to 50 percent of patients where the bone marrow fibrosis is actually reversed. 

And this is really something that we haven’t seen with other agents. And the approved agents, when that does happen, it’s really in a vast, vast minority of patients. And so, these newer drugs and, often, they’re used in combination with other approved drugs, can reverse the fibrosis in the marrow. And that is what I find most intriguing and exciting. They seem to be well-tolerated medications with predictable and reversible side effects when they do exist. And I think that time will tell if the promise is long-lived or if it’s short-lived. I mean, obviously, new drugs we don’t have the experience with that we really need. 

The clinical trials that are available now with some of these agents are in the last stages before the companies go to the FDA seeking approval for use. 

And so, we don’t have their results from those studies yet. They’re just opening, so sometimes the excitement doesn’t bear out when we do the rigorous clinical trials. But I’m actually quite optimistic about some of these agents, and I think that there is going to really be a sea change in how we treat patients and some of the outcomes we can expect from our therapies.

Katherine Banwell:

What are the considerations when choosing treatment for myelofibrosis?  

Dr. Scandura:

I would say in broad strokes, the primary considerations are the patient, what they want, the disease, what our options are, and the overall condition in terms of what are our possibilities for therapy and what is the risk/benefit of some of these different therapies. So, in myelofibrosis, although there’s been a huge amount of research over the past 10 years, really blossoming and are very impressive in, I think, an exciting way, there really are only two therapies that are approved by the FDA in the treatment of myelofibrosis, and those both affect one class of agents. These are JAK2 inhibitors, and those can be ruxolitinib (Jakafi) and fedratinib (Inrebicare the two drugs that are approved. 

Now, we have a number of therapies that have been used off-label, meaning without FDA approval, so often and for so long that they’re considered alternative standards of therapy. These can be growth factors; these can be biological agents in certain situations. And then, clinical trials is really increasingly a common therapeutic option for patients.  

And then, on the most aggressive side, is hematopoietic stem cell transplant and allogeneic transplant getting blood-forming cells from another person and replacing the entire blood system through transplant. 

Katherine Banwell:

So, who is right for a stem cell transplant? 

Dr. Scandura:

I would say, first and foremost, an informed patient about the risks of transplant and a patient for whom a donor exists, and a good quality donor. Transplant is not an option for some people or if a donor can’t be identified, obviously. 

And it’s a patient for whom the risk balance, the risk/benefit balance is tipped so that the potential toxicity, frankly, of transplant is warranted. Transplant is our most aggressive therapy. Virtually every patient will have significant side effects from transplant. Some of them are short-lived, some of them can be chronic. People die from the consequences of transplant. And so, it’s not something that is considered in patients who are necessarily doing well or are frail. The risk of transplant versus the benefit may not be in favor of transplant at that time.  

My approach for transplant is to get advice from transplant physicians. I’m not a transplant physician, but I have colleagues who I refer to. 

And I refer in myelofibrosis fairly universally fairly early, with the rationale being that this is information. It is not a plan; it is to speak to a transplant, what kind of donor exists. If no donor exists, then transplant is not on the table. If we have a very good, high-quality donor, then this is something that wouldn’t make the decision in itself, but it’s kind of something we can keep in our hip pocket in case we need it. And I think it’s important for patients to understand and have a full and complete discussion with a transplant physician so they understand what that means. You know, it is a significant commitment of time and morbidity, and it comes with risks. 

It is also our only curative therapy. And so, it’s a double-edged sword, and I think informed patients and understanding what the options are are the gateway to any consideration of transplant.

Katherine Banwell:

Dr. Scandura, would you start by introducing yourself?  

Dr. Scandura:

Sure. My name’s Joe ScanduraI’m an assistant professor at Weill Cornell Medicine in New York City. I’m a physician scientist. My laboratory studies blood formation, normal and malignant, and clinically I treat people with  myeloid neoplasms, particularly, and myeloproliferative neoplasms.  

Katherine Banwell:

Would you define myelofibrosis for us, and also provide an explanation of primary versus secondary myelofibrosis? 

Dr. Scandura:

Sure. Myelofibrosis is in the class of diseases called myeloproliferative neoplasms. And, really, its sort of marker feature is scarring in the bone marrow.  

Clinically, this comes along most commonly and fairly universally with anemia, and there can be abnormalities of both the white blood cell count and the platelet count, sometimes, often in the beginning, being too high. And then they can also become too low. 

It tends to be a progressive disease, or on the face on which it progresses is different in different people and there are a variety of different features that can go along with risk. But every individual, of course, is individual.  

A primary myelofibrosis is what we refer to when the diagnosis is made and there’s no antecedent, there’s no precursor malignancy. And so, you come in and the diagnosis is myelofibrosis, and we can’t find anything that came before it.  

Secondary myelofibrosis is what we refer to when somebody has another blood disorder, usually essential thrombocythemia or polycythemia vera, and in a small subset of these patients, the disease can change, what we call evolve or progress into a fibrotic phenotype or associated with the marrow scarring, and a lot of the features of myelofibrosis. Although there are some subtle differences between primary and secondary, they’re more similar than different in terms of their clinical features and how we treat them.

Katherine Banwell:

How does inhibitor therapy work to treat myelofibrosis? 

Dr. Scandura:

So, the therapies that we have now that are approved therapies that are in this class are  ruxolitinib (Jakafi) and fedratinib (Inrebic) 

Both of these agents act to block signaling through a protein called JAK2. You can think of JAK2 as being part of the antennae system that a cell uses to communicate with the rest of the body. And so, our blood-forming cells have a lot of input from the body saying, “Okay, we need some of these kinds of cells, we need some of those kinds of cells,” and it’s a very adaptive system. And JAK2 is involved in a lot of the signaling in this as part of the antennae system.  

And what happens in the myeloproliferative neoplasms is that signaling is a bit excessive. 

And so, it’s like the volume is turned up too loud and the signaling is causing the cells to do things, make too many cells, make the wrong kinds of cells, and JAK2 is part of that signaling system. So, these inhibitors kind of help turn down the volume of the signaling in these blood-forming cells. They are drugs that have good activity in improving symptoms, they have great success in reducing the size of the spleen, they can be useful for a few years to many years. They are not curative therapies. We don’t think of them as therapies that change the course of disease, but they certainly have an important role in helping people feel better. There are other inhibitor therapies that are in clinical development. 

So, clinical trials of some of these drugs have really impressive activity, but none is approved yet by the FDA.  

I hope and expect we’ll have a couple more drugs available in the coming years. And there’s a lot of excitement in clinical trials in terms of some of the activities that are being seen, and really quite tolerable therapies, so not a lot of side effects for patients. And so, I think it’s kind of an exciting time for physicians and for patients and a lot more options now and, I think, a lot more options coming down the line.

Katherine Banwell:

Are there gene mutations that affect myelofibrosis treatment choices? 

Dr. Scandura:

Yeah. So, you know, the primary mutations in JAK2 or CALR or MPL in myelofibrosis aren’t that helpful in guiding therapy.  

And we look at the other genes for co-ocurrent mutations and those, as I was mentioning before, can come into one of two categories. So, there are a number of genes that we know tend to confer a higher risk, and so we call those high molecular risk mutations. And people who have higher molecular risk tend to have a more aggressive disease. 

Now, I want to add a word of caution because when we talk about patients and risk, we’re talking about groups of patients. For any individual, everything kind of boils down to it happens, or it doesn’t happen. And so, there’s nobody is 50 percent dead in five years, right. You either are or you’re not. And so, when we talk about risk, then we’re talking about risk of bad things happening like death or other complications of the disease, we’re trying to guide treatment decision-making and guided discussion based on a chance.  

But all of those things, for any individual, there are people who have high risk who do quite well for a long period of time, and people who don’t have high risk who don’t do as well as you think they should. And so, it’s a part of a conversation, it helps guide discussion, but it is not something carved into stone, and nobody has a perfect ability to predict anybody’s future. 

And all of these things are our best tools to estimate, but they are not a future; they are a possibility. And so, people who have higher molecular risk, we might think about more aggressive treatments than people who have lower molecular risk.
