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.

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.

Transcript:

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.

Essential Testing Following a Prostate Cancer Diagnosis 


Transcript:

Every advanced prostate cancer patient is unique AND so is their disease. Advances in research are making personalized medicine a reality, tailoring care and therapy choices based on the genetic makeup and individual characteristics of a patient’s disease.   

As prostate cancer research evolves and treatment options expand, it’s vital that patients work with their healthcare team to find the best treatment approach to treat their specific cancer.  

An essential step to accessing personalized medicine is biomarker testing, which identifies key markers such as genes, proteins, or other molecules in a sample of tissue, blood, or other bodily fluid. The results of these tests can provide a fuller picture of the prostate cancer’s type, stage, and aggressiveness and may help predict how the cancer will behave. 

The test results can also identify which treatment approach may be most effective, through the presence of certain molecular markers.  For example, if a tumor has either high microsatellite instability (MSI high) or mismatch repair defects (dMMR), a prostate cancer patient may benefit from immunotherapy. Or a PARP inhibitor therapy may be more effective if the presence of mutations in certain DNA damage repair genes is detected. 

In addition to biomarker test results, other factors that physicians consider when recommending a treatment approach include:  

  • A patient’s age, overall health, and any pre-existing conditions. 
  • The type, stage, and grade of prostate cancer. 
  • And, potential side effects or impact on their lifestyle. 
  • And, the patient’s preference. 

Along with these considerations, it’s vital that patients discuss the benefits and drawbacks of each option with their team. So, how can you be proactive in order to access personalized care? 

  • Ensure that your doctor has experience treating prostate cancer. Consider consulting a specialist or obtaining a second opinion, so you can feel confident in your diagnosis and treatment plan. 
  • Ask a friend or loved to join you during key discussions with your provider, to help you process the information and to make decisions. 
  • And, be sure to request all essential testing, including biomarker testing, and ask how the results may affect your prognosis and treatment options.  
  • Discuss ALL of the treatments available to you, including any potential side effects.  
  • And ask if there is a clinical trial that could be right for you.
  • Finally, and most importantly, YOU should be at the center of your prostate cancer care. Share your opinions and ask questions throughout the process, so you feel empowered and informed.

Lisa Hatfield:

Another patient is asking if you can speak to emerging treatment options for patients with relapsed/refractory follicular lymphoma?

Dr. Sameh Gaballa:

Yeah. So the field of follicular lymphoma is changing rapidly. I always tell patients that sometimes the best treatment is actually on a clinical trial because those are going to be the next generation of treatments that are going to get approved in the next few years. But right now we have the most effective therapy really is CAR T-cell therapy. CAR T-cell therapy by far is the most effective treatment we have at this time. It’s approved for patients who have had two or more lines of prior therapies. We also are investigating this. I actually have a trial here at Moffitt where we’re looking at CAR T-cell therapy as early as in the second line, in patients who have what we call the high-risk ones, the POD24. So a patient with POD24 follicular lymphoma relapsed in less than two years. We have a trial to investigate the role of CAR T-cell therapy in this setting. The other very promising group of treatments, again, is bispecific antibodies, again, currently approved in the third line, mosunetuzumab-axgb (Lunsumio).

But there are others coming up and have data on epcoritamab-bysp (Epkinly), as well as a lot of other bispecifics, as well as combinations. I mean, epcoritamab-bysp has also data presented with combination with lenalidomide. And right now, the follow-up duration is not very long, but so far, it looks extremely promising with very high response rates. So those also might be coming very soon. And, of course, once something works in the relapsed/refractory setting, we start looking at earlier lines of therapy. And actually, we’re now looking at trials in the first-line setting with some of these agents as well. Tazemetostat (Tazverik) is a pill. It’s also approved in the third-line setting, but we’re also investigating it. We have a trial here where we’re looking at combining it with standard rituximab (Rituxan), lenalidomide (Revlimid), so tazemetostat plus rituximab, lenalidomide as early as in the second line. So that also is interesting. And as I mentioned before, BTK inhibitors currently being looked at in trials might also have a role in follicular lymphoma very soon.

Lisa Hatfield:

And this patient is asking about the significance of bispecific antibody treatment. And you touched on that a little bit. It looks like she’s also asking if there are specific genetic or molecular markers that can predict a patient’s response. And if I try to translate that, maybe she might be asking about targeted therapy.

Dr. Sameh Gaballa:

Yeah, so bispecific antibodies and CAR T-cell therapy, they target something called CD, either CD19 or CD20, and that’s almost universally expressed on B cells. So most of your follicular lymphoma patients are going to be expressing CD19 or CD20. Tazemetostat is the pill that I talked about. It inhibits an enzyme called EZH2. Some patients have an EZH2 mutation where it seems to work very well. However, tazemetostat also works in patients who don’t have that mutation. So that’s why it’s not very important to check for the mutation.

It seems maybe it works better in patients who do have the mutation, but it does work as well in patients who do not have that mutation. So unlike other malignancies and other cancers, biomarkers are not yet driving a lot of our treatment decisions in follicular lymphoma as of right now.

Lisa Hatfield:

How exactly do bispecific antibodies engage the patient’s immune system to target and eliminate follicular lymphoma cells?

Dr. Sameh Gaballa:

So bispecific antibodies are a very interesting class of medicines. It’s an antibody that has two ends to it. So one end would target the patient’s own immune cells, meaning that they would attach the antibody to the patient’s own immune cell and then the other end of the antibody engages the cancer cell. So it’s basically hand-holding the patient’s own immune system to go and kill the cancer cell. And this is not just in lymphoma. It’s looked at in multiple myeloma as well, approved therapies there. And a lot of other cancers, we have bispecific antibodies being developed in clinical trials right now.

Mikki:

Okay. Dr. Hoskins, fortunately, the endometrial cancer arsenal keeps expanding. What promising treatments are available to patients facing advanced endometrial cancer diagnosis?

Dr. Ebony Hoskins:

So, in recent years, we’ve had more research dollars into endometrial cancer that wasn’t there, say even five to 10 years ago. Some of the promising treatments that are coming about, are treatments that look at the molecular markers, meaning when we look at the tumor, and determining what proteins that are upregulated or down, now we have treatments that can more target, if you will, the specific cancer. So I think, these are definitely promising.

Other promising things that are occurring is that we are having more clinical trials that are offered for patients with advanced endometrial cancer that I know in my earlier years in practice or even in training, that just were not there. So I think this is a good time in the advancement in terms of endometrial cancer.

So my activation tip for this would be if a patient is newly diagnosed with endometrial cancer, is going in, knowing that we have more molecular markers, “Hey, are you going to send my tumor for next-generation sequencing, or are you going to be looking at the tumor for more information about targets that we could use for treatment?”

So those are questions that as a patient you can ask, because now these treatments are covered, and the testing is covered. And so we’re in a different realm than we were say, even five to 10 years ago.

In terms of targeted therapy, there are new drugs that are coming out that are targeting a different molecular markers in the actual tumor that are now offered for patients with ovarian cancer. And that’s been shown to be proven to work and improve the response and survival. My activation tip, particularly for patients who are affected by ovarian cancer, is asking, “Has my tumor been studied, or has there been any sequencing to determine if they are a candidate for targeted therapy?”

Dr. Jhanelle Gray:

My name is Dr. Jhanelle Gray, and I’m a clinical investigator focused on helping patients with non-small cell lung cancer (NSCLC). My research has concentrated on evaluating novel molecular markers and developing cutting-edge, personalized combination therapeutics to improve the outcomes of patients with non-small cell lung cancer.

Biomarker testing is so important to explain to patients, and I’ve learned some best practices along the way. I think it’s very important that we take the time to think about patients when we’re making decisions, and to be open to the idea that people think differently. We all come from different backgrounds, we have different experiences. I think trying to have empathy, taking a pause, and intentionally being an active listener are very important when a patient is sitting in front of you.

We need to be careful when we use the words manage or managing. We’re not managing the patient, what we’re doing is managing the therapies, we’re helping to manage the symptoms that patients experience. We also want to take time to slow down, look at what is happening in the room as you’re talking, as the patient’s talking to you…

Language is something that is critically important. When you’re delivering negative news, people will remember about 10 percent of what you say. There’s a lot going on, so patience is very important, using words that can resonate and land, and being open to questions are key. Making sure that, again, that you don’t judge and remember that you’re delivering a lot of information. We also must share the news in a culturally sensitive way and understand the dynamics. Again, it’s reading  the room.

Understand that this is an individual conversation. When the next patient comes in, you’re going to tailor the conversation to that individual. When the next patient comes in, you’re going to tailor the conversation to that individual. 

There are also some things to keep in mind about management. Patients do not fail therapies, our therapies fail our patients. And even when you’re talking to patients, you need to let them know, this is one of the things that can occur. While the intention might be to prepare them for what can happen in the future, you may not realize during the conversation that this could come across as blaming. 

Training is one of the ways that you can move this forward and also just pay attention, be thoughtful, and make sure that people feel as comfortable as possible when you need to deliver difficult news. Another time this becomes very important, is when you need to change therapies.

For the patients, they had gotten accustomed to a therapy, they knew how to take care of themselves, how to work with their team, and had familiarity with the side effects. And now you’re going to pivot treatments. To patients, this often feels like starting over from scratch. Thus, I think there are many sensitivities that must be considered, and we need to be thoughtful at those particular times.

I think that all providers should undergo cultural competency training. This can drive impact and help move us to the next level of reaching for that equity and honestly, lessening the inequities in healthcare.

Some things I’ve learned about communicating biomarker results with patients include:

  • Seeing patients as human beings first and the cancer as second.
  • Pause and think about what you’re saying and how you’re saying it.
  • Take your time and don’t rush the appointment.
  • Get to know your patient as a person.

For me, these actions are key to empowering my patients.

Laura Beth:

How do test results impact AML care and treatment decisions?  

Dr. Ravandi:

So, in the first place, the presence or absence of certain mutations can be predictable outcome. Some subsets of leukemias are, for the lack of a better term, more favorable.  

I personally don’t think there is anything favorable about any leukemia, but some are easier to treat, and some are easier to cure than others. There is one specific subtype called acute promyelocytic leukemia that we actually completely treat differently. We don’t use even chemotherapy in that subset of leukemia.  

It has almost 100 percent success rate. And the treatment of other subsets can also be tailored, depending on these molecular and chromosomal changes. So, the initial therapy can be actually changed. There are now, for example, targeted agents that can be added to the chemotherapy, during initial chemotherapy.  

And also, once the patient is in remission, depending on favorable or unfavorable their leukemia is, they may be offered allogeneic stem cell transplant. So, yes, this information is highly important. In fact, I would say crucial for our decision-making in leukemia therapy these days.  

Laura Beth:

So, what is new in AML research related to molecular markers?  

Dr. Ravandi:

Well, it depends on your definition of new, but FLT3 mutations are very important because they’re now several FLT3 inhibitors, and as I mentioned, the initial therapies are different, to some extent. The IDH mutations are very important, again, because they are specific targeted agents.  

TP53 mutations are important because, unfortunately, they are particularly unfavorable.  

This is completely hot off the press, but there are subsets of AML called MLL rearranged leukemias that can respond to these drugs called Menin inhibitors.  

There are other mutations that have been discovered, many other ones, that there are no specific treatments for at the moment, but there’s a lot of research on.

Katherine Banwell:

Dr. Pemmaraju, let’s talk about biomarker testing. Can you help us understand what biomarkers are and how they may affect treatments?

Dr. Pemmaraju:     

Yes. Biomarkers – I think that word gets mentioned a lot with really no definition, because it’s one of those words that can be whatever someone wants it to be. So, you’re right. For us, it’s a very important word in MPN. Bio meaning of life, scientific, and then marker meaning some kind of a measuring stick that has a value.

Well, there are two ways to look at biomarkers. One is the obvious, which is we have the defined big three molecular mutations. So, that’s JAK2V617F, followed by CALR mutation, followed by MPL.

Those are the big three. Those make up about 90 percent of all patients with MPNs. You’re technically not born with them, although new data suggests that you may acquire these mutations right after birth. So, those markers are important because they can be used to diagnose the disease, right? Particularly in the challenging patient. They have high platelets, you can’t tell if it’s reactive or ET. Okay, so they’re helpful with diagnosis.

Maybe some studies have shown that some of these markers can be predictive, Katherine, of blood clots. Let that research be ongoing. And then, obviously, some of these may be helpful in terms of designing the future treatments, particularly targeted therapies. So, I think biomarkers are part of our field, if you look at it that way, at diagnosis and risk stratification prognosis. But there are other factors that are starting to come out. One is there are molecular mutations outside of these big three.

So, outside of JAK2, CALR, and MPL, that are very important actually. Not everyone is checking for them. They are ASXL1 mutations, EZH2, IDH1 and 2, so on and so forth.

So, these are extended molecular markers that can be checked at some doctors’ offices that now, in the latest scoring systems, if you have one of those or more than one or two, they can elevate your risk score. So, if you have low risk or intermediate risk myelofibrosis, they may make you intermediate or high risk.

So, that may be a bit more complicated than what most people are aware of. But just so you know, there are markers that can be readily checked that can tell if your disease may be a bit higher risk than we though, say, 10 years ago.

I think other biomarkers that we look at are some of the labs that are just the regular labs that are on almost every panel, but they can tell a lot about the disease. There’s the LDH, lactate dehydrogenase. There are several markers, such as CRP and sed rate.

So, anyway, there are a lot of labs that we can check depending on where you are in your disease state that can kind of tell us a lot about how inflamed you are, how active your disease is at the moment, and then that will lead to further confirmatory tests. So, I think, yeah, in general, this is an active, developing area of research in our MPN field.
