MPN Treatments and Clinical Trials Archives

When it comes to treatment, MPN patients and their care partners have much to consider. There are often many options available, each with advantages and disadvantages. Some people may seek clinical trials, others may have few feasible options. Understanding treatment options, goals, and what to expect are vital to achieving the best possible outcome for you.

What Are the Treatment Options for Myelofibrosis?


Transcript:

Dr. Stein:                   

Clinical trials are always a treatment – always an option for patients with myeloproliferative neoplasms because while we have some standards, we can definitely improve upon those standards for certain. So, clinical trials are always a therapeutic option. I think the one thing is that it may not – it’s not always the most convenient option, but it could be a really important option if available to you.

So, clinical trials basically offer something new or novel that would not otherwise be available to other patients. So, ruxolitinib (Jakafi) was approved around 2011, but the first clinical trials were in 2007, so that’s the example I give to a patient about the benefit of a clinical trial.The patient can get access to a drug that’s effective perhaps three to four years before it’s commercially available.

That’s really the biggest advantage, is you can get early access to something that could really help you. The downsides are that clinical trials are not usually as convenient as regular care, there are often more visits, and there are a lot of unknowns – unknowns about whether it will work. Some side effects are known and expected; there are others that are unknown. So, it’s a lot to think about, but I think it’s always important to consider, especially if your first-line therapy has not been effective, if it’s losing its touch, it’s a good thing to think about for a second line.

Katherine:                  

Are there emerging approaches for treating MPNs that patients should know about?

Dr. Stein:                   

Yeah, absolutely. I think the first question – I think patients are often worried that they have a really rare disease, and why would anyone do research in this area, and that’s – the research community is extremely engaged, the productivity is pretty impressive, and there’s a lot of clinical trials in the space, and I think what I try to explain is pharmaceutical companies aren’t just targeting the most common diseases.

They have interests in rare diseases, and findings in rare diseases can be extrapolated to other diseases that you might think are unrelated, but they can share features, so when you find something working in one space, it can have broad applicability. So, there’s an abundance of research in myeloproliferative neoplasms which are emerging?

In PV, I think there’s quite a possibility that there’ll be a drug approval in 2021, a novel type of interferon called ropeginterferon

That is a drug that’s approved abroad; it’s approved in Europe, and I believe it’s approved in Taiwan, and the FDA is looking at it now. So, it’s a possibility that there’ll be a future option for patients with polycythemia vera. So, yes, it’s research now, but it could be available, and so, that’s the drug that I’m starting to talk more and more about for patients with PV.

In myelofibrosis, you have two JAK inhibitors that are approved, ruxolitinib and fedratinib, you have two others in clinical testing, momelotinib and pacritinib, and then you have a whole other class of what we call non-JAK2 type of therapies targeting the vast array of pathway abnormalities in myelofibrosis.

So, there are a number of different clinical trial options, especially in myelofibrosis. I think that’s the disease area where there are the most clinical trials.

Dr. Stein:                  

For ET and PV, when we talk about high versus low risk, we’re talking about vascular complications, risk of having a blood clot. We’re not really talking about risk of transformation. We don’t have, I think, wonderful, widely used toolkits to predict those things. We know they can happen, but our treatment is still really based on clotting for ET and PV.

And, MF – each couple of years, the tools that are available to assess prognosis become more and more. So, in MF, we’re using the most comprehensive approach – of course, taking into account things like age and demographics, but also, looking at symptoms, looking at the depth and severity of blood count changes, looking at bone marrow features like the degree of scarring, looking at the rise in blast counts, and then, looking at chromosomes and novel genetic markers. So, we’re definitely the most comprehensive in myelofibrosis at assessing prognosis.

MPN Treatment: Why Testing for Mutations Matters


Transcript:

Katherine:                  

Let’s start with essential thrombocythemia, or ET.

Dr. Stein:                   

So, I think the first thing is taking an inventory of symptoms, seeing how symptomatic the patient might be. Again, there are some patients who are asymptomatic or have few symptoms, and they were told of a high platelet count during a routine visit, so some patients can be observed if they have few symptoms, and especially if they fall into a lower vascular risk category.

So, symptom assessment first. Second, looking at vascular risk, and there are four categories of risk in in ET in terms of predicting the likelihood of a future blood clotting event. There’s a very low, low, intermediate and high risk group, and that’s based on a patient’s age, whether they’ve had a blood clot before, and the type of mutation they have. JAK2 mutations increase the risk of clotting.

So, if a patient falls into a higher-risk group – say they’re older than 60 with a JAK2 mutation or they’ve had a prior blood clot – those are patients who are generally treated more aggressively with cytoreduction.

And then, the other thing is aspirin. We often see aspirin given to all patients with ET, but not all patients with ET necessarily need it. The role of aspirin is actually a little less clear in ET. For a very low-risk patient, there’s a potential for more harm than benefit, especially if the patient lacks a JAK2 mutation. So, the evidence base to support aspirin for all ET patients is just not there; it’s evolving.

Katherine:                  

What about polycythemia vera, or PV?

Dr. Stein:                   

So, there are a few standards. It’s different – the aspirin question in PV is generally answered by randomized data from 16 years ago in 2004. It’s been shown that aspirin reduces the risk of clotting in PV patients, so, generally, we give low-dose aspirin to all patients. And, hematocrit control is really important.

At least, a goal of 45 percent is mandated in PV. And then, there are patients who might fall into a higher-risk category – older than 60 or have had a prior blood clot – they need something more. And then, I’d also emphasize that there are lower-risk patients who may not be traditional candidates for cytoreduction, but they could have symptoms that really interfere with quality of life, and symptoms alone can be the trigger to add something more to the phlebotomy and aspirin program.

Katherine:                  

What about things like interferon?

Dr. Stein:                   

So, interferons have been used in MPNs for decades and decades. So, a longstanding history with interferons. The issue has been tolerability.

These days, there’s a class called pegylated interferon that’s longer acting, and I think there’s been a lot more use, at least in the last 10 years, still much more in an academic setting than a community practice.

But, interferons have a pretty established role in MPNs, especially polycythemia vera, for sure in ET, less so in myelofibrosis.

What Factors Guide Treatment Choices for ET, PV & MF?

When making a myeloproliferative neoplasm (MPN) treatment decision, several factors come into play. Dr. Brady Stein explains what criteria he considers to determine the optimal approach for a patient’s unique situation and specific MPN.

An Expert Shares Key Steps to Take Following an MPN Diagnosis

MPN Treatment: Why Testing for Mutations Matters


Transcript:

Katherine:              

Dr. Stein, I understand that therapy is different for each of the MPNs. What do you take into consideration to help guide the treatment choice?

Dr. Stein:                   

So, that’s a good question. It’s going to require maybe a little bit of a longer answer. It’s fairly nuanced. The treatment of ET and PV – right now, the goals are – the treatment is largely based on a patient’s vascular risk. That’s largely what influences the choice of therapy. And so if a patient has a perceived high risk for vascular complication in ET or PV, that’s when we’re going to be a little bit more aggressive – so, more aggressive than watchful waiting, more aggressive than using aspirin alone, more aggressive than using phlebotomy and aspirin alone in polycythemia vera.

So, if the patient has a higher vascular risk, in general, we’re going to need to do something more than what we consider to be the standard, and that’s where we enter into the question of cytoreductive therapy – therapies designed to lower blood counts apart from phlebotomy.

Maybe that’s going to change. I hope it will change. Right now, the therapy for ET and PV is generally reactive. We either predict high risk and react, or if a patient is lower risk, if something changes – God forbid there’s a blood clotting event – then we may react to it.

So, ET and PV treatment are generally more reactive. In myelofibrosis, certainly, there are patients who can have lower risk and minimal systems, and there are some patients who can be observed with watchful waiting for sure, but more patients are symptomatic, more patients are going to need therapy in myelofibrosis, and there’s sort of two big categories of therapy.

One is the risk-adapted, deciding if the patient is eligible and should consider stem cell transplant versus thinking only about medical therapy in a patient that may be transplant-ineligible.

And, the medical therapy is based on the worst symptoms for the patient. Is the symptom that’s the worst the spleen enlargement? Is it excessive fatigue? Is it weight loss, or inflammation, or fevers? If it’s that category of symptoms, we have a set of therapies. If it’s really the anemia that is the most problematic issue, then we follow a paradigm to treat anemia.

Katherine:                  

What about considerations like the patient’s health, age, genetic markers, things like that?

Dr. Stein:                   

So, of course. The comorbid illnesses can influence therapy choices, so if a patient is older and has other medical conditions, they’re not going to be treated as aggressively.

So, in myelofibrosis, if a patient is older, with other medical illnesses, then it may be inappropriate to consider something like stem cell transplant, for sure. So, age and health comorbidities are highly influential. In terms of genetic features, if you’re asking about things like the type of mutation that a patient has, right now, we’re – in terms of vascular risk, for ET, the type of mutation matters for blood clotting risk, so if patients have different mutations, it could be treated differently. In other subtypes, like PV or myelofibrosis, in general, there’s – the mutation can be prognostic, but it may not be – it may not lead to a precise and distinct therapy just yet.

MPN Treatment: Why Testing for Mutations Matters


Transcript:

Katherine:                  

Once a patient is diagnosed with MPN, what sort of testing should take place?

Dr. Stein:                   

So, the test that’s going to lead to suspicion is going to be a blood count, and that’s probably going to be done in the primary care doctor’s office, so that’s going to be the first suspicious test, and in general, there’s going to be some abnormality. Myeloproliferative diseases are characterized in general by an overproduction of blood cells, so it’s going to be a higher white count, it’s going to be a high hemoglobin or hematocrit, or a high platelet count, or a combination of the three that’s generally going to lead to suspicion.

Some patients may have pretty unremarkable blood counts and may present with a blood clot in an unusual location that could ultimately lead to the hematology referral. Some patients might have pretty unremarkable blood counts, but they might have palpation of their spleen, enlargement of their spleen in a physical examination. So, they’re generally the ways that patients are getting to the hematologist.

Katherine:                  

And, what about bone marrow biopsy?

Dr. Stein:                   

So, a bone marrow biopsy is a diagnostic test, and it’s generally recommended for all patients who have a myeloproliferative neoplasm either confirmed or suspected.

It’s advised in WHO criteria – World Health Organization criteria. PV can be made without a bone marrow biopsy – a diagnosis of PV – because it’s the most unique of the MPN subtypes. It’s the one that presents with a high hemoglobin.

So, that diagnosis can be straightforward at times for a hematologist when the setting is right, when there’s a high hemoglobin – or, high enough hemoglobin, I should say, a JAK2 mutation, which all patients with PV have that, or a subnormal erythropoietin level.

Oftentimes, we can make that diagnosis without a bone marrow, and the bone marrow becomes more prognostic. ET, a bone marrow is necessary for diagnosis, and myelofibrosis, you can’t make a diagnosis without it.

Katherine:                  

What do the results of these tests tell us about prognosis and treatment choices?

Dr. Stein:                   

That’s a good question. The bone marrow can be diagnostic in the setting of ET and myelofibrosis. In the setting of polycythemia vera, it can be more prognostic. In general, when a bone marrow is done, 1). To confirm diagnosis, 2). To assess prognosis, what we’re looking for as prognostic features are generally the degree of fibrosis or scarring.

So, each of the MPNs can have that. Of course, MF is characterized by the most pronounced scarring. It can happen to a more subtle degree in ET and PV. That’s going to be prognostic in the setting of ET or PV. The pathologist will alert us about immature cells called blasts.

We basically never see them at diagnosis in patients with ET or PV. We can see them rise in patients with myelofibrosis at diagnosis or through the course of follow-up. So, that’s prognostic.

All bone marrows generally have a chromosome analysis that’s called cytogenetics, and so, if there’s an abnormality, that can help place the patient’s prognosis into different risk categories.

And then, nowadays, more so in myelofibrosis than any of the others, there are extended panels done. These are called NGS, or next-generation sequencing, kind of looking at mutations in a greater degree of detail.

So, not just what we call main mutations – JAK2, calreticulin, or MPL. These are looking at additional mutations that basically hold prognostic significance.

These are pretty well defined, and I think more important in MF compared to the other subtypes.

Katherine:                  

Would you explain the driver mutations in MPNs? What are they, and how they – or, what they mean for patients?

Dr. Stein:                   

So, there’s three of what we call driver mutations, and the most common is JAK2V617F, the next most common is calreticulin, and the least common or most rare is a mutation of MPL, the thrombopoietin receptor. So, the driver gene mutations are the three that we assess to help with diagnosis, and the prevalence varies. In ET, about 60 percent have JAK2, 25 percent have calreticulin, 5 to 10 percent have MPL.

In PV, 99 percent have some type of JAK2 mutation, and in MF, the situation is a lot like ET – 60 percent JAK2, 25 percent calreticulin, about 5 to 10 percent MPL. So, the driver mutations – we think of those as the genetic abnormalities that really drive the disease. They’re the main ones we can test for in a diagnostic setting.

I refer to them as the – to a patient, what I’m describing is you have a car, and the driver mutation is the one that’s sort of driving the car, and it’s doing it somewhat recklessly. It’s in the front seat, driving. And, along the way, the driver can pick up hitchhikers, which we should never do. I refer to those other mutations that are found by NGS as hitchhiker mutations that sit in the back seat, cause trouble, and really shouldn’t be there. They’re not the driver, they’re not fully responsible for the disease, but they can make it a bit worse.

Could an MPN Clinical Trial Be Right for You?


Transcript:

Dr. Michaelis:                       

So, there’s lots and lots of research going on in the field of myeloproliferative neoplasms. One of the best ways to stay informed about this is to check on something called clinicaltrials.gov, which is a national website that warehouses clinical trials in the disease that you might have.

So, if you look up essential thrombocythemia or you look up myelofibrosis, it will show you the clinical trials that are going on in your region, in your state, or in the country. So, that’s a nice way to begin to look and see what’s available.

The other way, of course, is to talk to your doctor. And each institution has a list of clinical trials that they have open, based on what a person’s diagnosis is, what their age is, what other, for example, health issues that they might have. And so, again, when you’re talking to your doctor, say – Is there something I should be thinking about, in terms of clinical trials?

There are clinical trials going on in all facets of the disease – not just in treatment, which is what you often think about. Treatment for symptoms or treatment for ways to control the disease. There are new medicines coming down the road, in terms of what to do when somebody is no longer responding to treatment. Or how can we combine treatments together? Those are important trials, and those are things that people should talk with about their physician.

But there’s also clinical trials on symptom management, and those can sometimes be a trial that you would do online yoga or dietary trials. And there’s trials on familial syndromes, meaning – Yeah, I have polycythemia vera, and my aunt had myelofibrosis, and her daughter has ET. Well, that is a family that should be investigated. And sometimes we find that – even nationally, we find that we’re networking with one another and collecting patients who have family histories so we can learn more about that.

So, there’s a variety of different types of clinical trials. Those are things to talk to your doctor about. And on your own, you can search them out on clinicaltrials.gov or through patient advocacy organizations.

MPN Treatment Decisions: Which Path is Best for You?


Transcript:

Dr. Michaelis:                       

So, myelofibrosis is among the most aggressive of the myeloproliferative neoplasms. And yet, it still has a broad swath of risk associated with it. And that means that compared to essential thrombocythemia and polycythemia vera, myelofibrosis – primary myelofibrosis tends to be more aggressive and needs to be treated more aggressively.

There are a group of patients who have what we call low-risk or even intermediate 1 risk myelofibrosis who don’t need treatment – who can be followed, whose blood counts can be checked, who can be regularly seen by their doctor, and who can avoid treatment for some period of time, depending on their risk factors.

And so, if you’re diagnosed with primary myelofibrosis, the first question is do I need treatment? And the second question – if the answer to that is yes, then you have to figure out why you need treatment. There is currently only one intervention that is known to be curative in myelofibrosis, and that’s the use of stem cell transplant.

Stem cell transplant, which is also called bone marrow transplant or allogeneic hematopoietic stem cell transplant, is basically a procedure where a donor is able to have their stem cells collected. And then the recipient, who’s the person with the myelofibrosis, undergoes a series of chemotherapy treatments to basically wipe out the bone marrow that they have. And it’s then replaced, using basically a blood transfusion of the stem cells of someone else, which then grow up into the recipient.

This has been shown to be safe in myelofibrosis – well, relatively safe – if done in the right person, who’s relatively fit, and done at the right stage of disease. It’s not a procedure that everybody can tolerate. People need to be pretty fit. And it should be performed at a place that has done numerous transplants for myelofibrosis since it’s a relatively complicated form of stem cell transplant. That being said, in the right person at the right time, it’s an excellent opportunity and option for these patients.

Now in patients who can’t tolerate transplant or where that’s not the right step to go, we have medications. And those medications can sometimes delay the worsening of symptoms. They can certainly control spleen size, improve people’s quality of life, and often improve survival. And the medications that we’re talking about here are called JAK-STAT inhibitors.

And the first approved, and the one that’s most commonly used, is a medicine called ruxolitinib.

This is an oral pill – a pill that you take twice a day and has excellent data that supports that it shrinks the spleen in people with myelofibrosis, that it improves symptoms. And in people with advanced polycythemia vera, decreases the blood count without leading to iron deficiency and also improves symptoms and spleen size.

There’s another JAK-STAT inhibitor that’s approved. That’s a medicine called fedratinib. And it was recently approved in people who had progressed off of myelofibrosis or even in people – or after ruxolitinib or in people who – instead of taking ruxolitinib.

Now in essential thrombocythemia, polycythemia vera, and other times even myelofibrosis, we have other treatments that are commonly used that can be exceedingly helpful in controlling symptoms and blood counts. Those include, for example, hydroxyurea, pegylated interferon, and sometimes treatments aimed at helping anemia, like steroids or derivatives of thalidomide.

And finally, I don’t want to let this end without saying that clinical trials are often an excellent possibility for patients with these conditions, like myelofibrosis.

So, when you are contemplating starting a treatment, it’s really important to ask your physician whether or not there’s any clinical trials that are right for you.

Confused About Immunotherapy and Its Side Effects? You Aren’t Alone

“You don’t look like you have cancer.”

More than one patient undergoing immunotherapy to treat cancer has reported hearing statements like that. Immunotherapy is one of the recent advances in cancer treatment that belie the stereotypes about the effects of cancer treatment. 

The side effects of immunotherapy are different from those associated with chemotherapy and radiation. However, that does not mean immunotherapy does not have side effects. Patients and care partners need to be aware of these potential side effects and to be vigilant in addressing them with their oncologists because they can signal more serious complications if left untreated.

What is Immunotherapy?

Despite the increase of immunotherapy treatment options in recent years and considerable media attention paid to advancements in this field, there remains confusion about immunotherapy and its side effects. Many cancer patients are unaware of whether immunotherapy treatments are available for their specific diagnosis. Others don’t know that genetic profiling of their tumors is usually required to determine if immunotherapy is an option and not all treatment centers routinely conduct genetic profiles of tumors. A  survey by The Cancer Support Community found that the majority of patients who received immunotherapy knew little to nothing about it prior to treatment and were unfamiliar with what to expect.

Immunotherapy works by manipulating the patient’s immune system to attack cancer cells. It is perceived as gentler and more natural than chemotherapy and radiation, without the same destructive effect on the body’s healthy tissues.  This, combined with a lack of prior understanding of immunotherapy, can lead patients and care partners ill-prepared for possible side effects.

Furthermore, immunotherapy is a category of therapies, not a single type of treatment. There are a variety of immunotherapy drugs, most of which are administered via infusion.  Side effects will vary by drug, the cancer and its location, treatment dose, and the patient’s overall health.

The following are the most common types of immunotherapy.

  • Checkpoint inhibitors use drugs to block proteins in the patient’s immune system that would otherwise restrain the immune system, often referred to as taking the “brakes” off the immune system.
  • CAR-T therapy modifies the patient’s T-cells in a lab to enhance their ability to bind to cancer cells and attack and kill them.
  • Oncolytic virus therapy uses genetically modified viruses to kill cancer cells.
  • Another therapy uses cytokines (small proteins that carry messages between cells) to stimulate the immune cells to attack cancer.

Immunotherapy can be part of combination therapy. It might be combined with chemotherapy. It might be used to shrink a tumor that is then surgically removed.  Or multiple immunotherapy drugs might be used simultaneously.

What Are The Side Effects?

With immunotherapies, side effects typically occur when the immune system gets too revved up from the treatment. The most common side effects for immunotherapy treatments are fatigue, headache, and fever with flu-like symptoms. Some people also experience general inflammation often in the form of a rash. Many melanoma patients report blotchy skin discoloration, called vitiligo, during treatment. These milder side effects can usually be managed with over-the-counter remedies and adjustments to daily activities.

For checkpoint inhibitors, the fastest growing segment of immunotherapy treatments, mild side effects occur in 30% – 50% of patients. Serious side effects typically occur in less than 5% of patients. (See “Understanding Immunotherapy Side Effects” from the National Comprehensive Cancer Network and the American Society of Clinical Oncology.)

Less common side effects are blisters, joint pain, thyroid inflammation, and colitis (inflamed colon resulting in diarrhea with cramping). Some patients who receive CAR T-cell therapy develop a condition known as cytokine release syndrome, which causes fever, elevated heart rate, low blood pressure, and rash. 

In rare cases, immunotherapy has resulted in lung inflammation, hepatitis, inflammation of the pituitary, and detrimental effects on the nervous and endocrine systems. In most cases, the conditions clear up when treatment ends.  However, there have been outcomes in which immunotherapy caused diabetes or tuberculosis.

“Overall there are fewer side effects [with immunotherapy],” explained Dr. Justin Gainor, a lung and esophageal cancer specialist at Mass General during an Immunotherapy Patient Summit hosted by the Cancer Research Institute. “But the immune system can affect anything from the top of the head down to the toes. Any organ has the potential to be affected.”

As the application of immunotherapy has expanded, so has our understanding of the potential side effects. Like most medical treatments, how one person responds to immunotherapy can be different from another even when the cancer diagnosis and drug therapy are the same.

The essential thing patients and care partners need to know about side effects is they should always be reported to their oncologist or nurse oncologist.

Why Patients Should Talk to Their Provider About Immunotherapy Side Effects

Because immunotherapy has created newer therapy options, there isn’t the volume of experiences as with older treatments. The infinite number of variables that patients provide once a treatment moves beyond clinical trials and into the general patient population generate more diverse outcomes.  And, as most therapies are less than 10 years old, there hasn’t been an opportunity to study the long-term effect of these therapies. This is why oncologists advise patients and their caregivers to be extra vigilant in noting any changes experienced during and after treatment.

Many side effects are easy to treat but medical providers want patients to be forthcoming in discussing any and all side effects. This is in part to improve understanding of side effects, but also because a mild cough or a case of diarrhea might be harbingers of a more systemic issue that will grow worse if left untreated.

Patients should not be hesitant to discuss side effects because they fear they will be taken off immunotherapy.  Sometimes a pause in treatment might be necessary, but the earlier the oncologist is made aware of a side effect, the less likely that will be necessary.

In addition, patients undergoing immunotherapy should always take the name(s) of their immunotherapy drugs and the name of their oncologist when seeing medical professionals outside of their cancer treatment team. This is especially important when visiting the ER.  Because immunotherapy drugs are newer and highly targeted to certain cancers, many medical professionals remain unfamiliar with drug interactions and treating related side effects.

Immunotherapy On The Rise

Immunotherapy treatments have resulted in reports of remission in cases that would’ve been deemed hopeless just five or 10 years ago.  The Federal Drug Administration (FDA) has approved various immunotherapy treatments for melanoma, lung cancer, head and neck cancer, bladder cancer, cervical cancer, liver cancer, stomach cancer, lymphoma, breast cancer, and most recently bladder cancer.  (Here is a list of  immunotherapies by cancer type from the Cancer Research Institute.)

“It’s revolutionized how we treat our patients,” says Dr. Gainor of Mass General about immunotherapy’s impact on lung and esophageal cancer.

Advances in immunotherapy research and trials continue to generate optimism and excitement. A clinical study in Houston is looking at using immunotherapy to prevent a recurrence. Researchers in Britain recently announced a discovery that might lead to advances in immunotherapy treatments to a much broader array of cancers.

While there is excitement around the field of immunotherapy and it has resulted in unprecedented success in treating some previously hard-to-treat cancers, it remains an option for a minority of cancer diagnoses.  It works best on solid tumors with more mutations, often referred to as having a high-mutational load or microsatellite instability (MSI) high. And it is not universally successful for every patient.

With hundreds of clinical trials involving immunotherapy alone or in combination with other therapies, it is certain more treatment options are on the horizon. As more therapies are developed and more patients with a greater variety of conditions undergo immunotherapy, we will also increase our understanding of potential side effects.

Side effects should not dissuade patients and care partners from considering immunotherapy if it is available or from advocating for genetic tests to deteimine if it is an option. Many patients undergoing immunotherapy have previously undergone chemotherapy and report that the side effects are fewer and milder by comparison.  The important thing is that patients and their partners know what to expect and communicate with their treatment team.

If the next 10 years in immunotherapy research and development are anything link eth elast 10, we can expect more exciting advancements in the battle against cancer. For more perspective on what’s ahead for immunotherapy see the Cancer Research Institute’s article: Cancer Immunotherapy in 2020 and Beyond.

Improving Life with MPNs: The Latest Research and How to Get Involved


Transcript:

Dr. Ruben Mesa:

There is much exciting research in myeloproliferative neoplasms. First, research trying to understand, why do people develop MPNs, and why do they progress. This is crucial research, and that this basic research to better understand the diseases will help us asses whether our treatments are having an impact slowing down the progression of the disease, and help us better design therapies that, hopefully, can cure these diseases.

Be reassured  that our goal as a scientific community is to cure the MPNs. Now, until we’re able to do that, we want to be able to best control them as best we can. So, the next level of research is really in new therapies; primarily drug-based therapies, but future therapies using the immune system; potentially using vaccine therapy to try to better control the disease to make the disease as neutral in your life as possible.

Our goal, short of curing the disease is to make the disease as invisible in your life as possible. Hopefully, minimal side effects, minimal symptoms, protected against risk of blood clots or bleeding, ideally, decreasing the risk of progression, and hopefully without any significant side effects from the medication your receiving.

So, that really is our goal.

 Clinical trials are a crucial way for us to improve the treatments that we have for any diseases. And in particular, in areas like myeloproliferative neoplasms where we have therapies, but we don’t have cures, clinical trials are crucial. Clinical trials are a structured way for you to be able to receive a new treatment. That treatment is closely monitored, and starts with a strong belief that that treatment is going to be beneficial for you.

Being on a clinical trial has many steps, but you are in the driver seat in each of them. So, you’re able to enroll in a study, and you’re able to decide at any point whether or not you’d like to continue on in that study. You are made clearly aware of what you’re receiving; what dose; what to expect at each and every step of that therapy.

It’s a treatment just like any other, but we use them because we are hoping that it will be better than the treatments that we have, and we do it on a clinical trial so that we can learn from that experience. If that drug is better, then we should probably expand its use and give it to other people, and have it be approved and used around the world. Or for whatever reason that therapy is not as helpful as we would like, then we learn from that, as well.

Why was it not helpful? Was it the wrong therapy? Was it targeting the wrong aspect of the disease? Were there side effects that made the therapy not beneficial? So, we learn a lot about it in either direction. Hopefully, individuals who participate in clinical trials will have a direct benefit themselves by being able to experience a new therapy that is, hopefully, better. But also, they do have the ability to help other patients now and in the future that will be facing the same disease they have.

Dr. Ruben Mesa:

The treatment landscape for myeloproliferative neoplasms is changing very rapidly. And in a good way, it’s increasingly having many more options for patients with Myeloproliferative Neoplasms. But I would separate it, really, into two groups. First, there are those individuals with essential thrombocythemia and polycythemia vera.

These individuals, we have newer therapies, such as interferons, we have, potentially, use of JAK inhibitors, we have some experimental therapies, as well as prior therapies we’ve used and become accustomed to, including hydroxyurea, phlebotomy, and aspirin.

But we’re learning much more about how to use these therapies; how to combine them; what constitutes success with these therapies; what should constitute a change in terms of therapy.

And there are new therapies being developed in the future that will impact this group of individuals with earlier MPNs: ET and PV.

For patients with myelofibrosis, the treatment is evolving. Patients with Myelofibrosis are affected in different ways. It is, in some ways, a more problematic disease.

There is evolution of our most impactful therapy, of stem cell transplantation. We have a better sense of in which patients we should consider that treatment, and how that can be applied in the safest way. We also have more medical treatments. We just saw in 2019 the approval of Fedratinib as the second specific JAK inhibitor approved for patients with myelofibrosis.

We, additionally, now have, truly dozens of clinical trials of new therapies in development that are in clinical trials right now that might be helpful for patients with myelofibrosis who have either had Ruxolitinib, or have a suboptimal response to Ruxolitinib, or sometimes even newly diagnosed patients. But I would say the future is very bright.

So, it is key with a treatment to first understand what is the treatment, what is the dose, and what is the goal? Each of the treatments have different goals. Some of the goals are to decrease the likelihood of blood clots or bleeding.

And frequently, we assess whether we’re protecting against the blood clots or bleeding by bringing down elevated counts. Is the plate account high, and we’re trying to bring it into the normal range? Is the hematocrit high, and we’re trying to bring that to under 45%? Is the white blood cell count high? Have we lowered each of those? First, it’s around controlling blood counts if that is the goal, as well as trying to decrease at risk of blood clots or bleeding.

 Second, if patients have symptoms associated with their MPN, sometimes itching, sometimes symptoms associated with high courts, sometimes enlargement of the spleen, or symptoms associated with the spleen, have we reduced or nullified those symptoms? Have we shrunk the spleen if the spleen was enlarged?

And then, finally, we assess our goal by trying to be sure that patients are not progressing or getting worse on the disease. So, depending upon the treatment, we first asses what is our goal? Is it to improve counts? Is it to improve symptoms? Is it to shrink the spleen? And have we accomplished one, two, or all three of those goals? Or was only one those our goals to begin with?

Lindsey:

When considering treatment, remembering that clinical trials are an option – and often, a very good choice – is something that I really try to communicate to my patients. Generally, there’s a stigma around clinical trials as patients feeling like a lab rat or some sort of a study subject, and there is a perception that they’re not receiving as good of care as they would if they were not on a clinical trial. However, in my patients, I really try to dismiss this thinking because at this point in time, we do have really fairly good options for treatments with MPNs.

However, we do not have a cure for MPNs outside of a transplant, and our treatments are not perfect, and so, enrolling in a clinical trial really should be considered by patients and their providers as a very viable option.

It’s generally introducing perhaps a new way of approaching the disease treatment. Oftentimes, clinical trials are using a combination of agents, which is not necessarily available outside of the clinical trial.

And so, with clinical trials, we’re always trying to make something better. We’re trying to learn something, we’re trying to, No. 1, help the patient – so, my No. 1 goal in enrolling one of my patients in a clinical trial is to, first of all, help them, help control their disease, help them to feel better, and to live a long and good life. No. 2, we learn as we go along. Clinical trials are critical for drug development and for the future of treatment in patients with MPNs.

So, not only are our patients helping themselves, but hopefully, they are helping the future MPN patients who may come along and need a treatment. So, I always like to keep this really in the conversation when discussing treatments, and it may be up front, and it also may be after a treatment has stopped working that we consider a clinical trial.

So, there are also a lot of things that kind of go into clinical trial management and different requirements, so if a patient lives very far away, it may be challenging for them to come back to the academic center on a regular basis for routine clinical trial monitoring that’s required by the study, but if they live close by, I generally do recommend this. They are also associated with clinical research coordinators or clinical trial nurses.

And, these patients are monitored really very closely, and it’s kind of nice to have that extra person in it with you in the clinical trial, just another point person to discuss, perhaps, how you’re feeling or different questions or concerns as the clinical trial proceeds. So, when talking about treatments, in my opinion, especially in MPNs, clinical trials really should be one of the options that is first discussed when thinking about starting treatment, and especially if a treatment has stopped working.

So, there are very many exciting possibilities in MPN research right now. We have a lot of combination therapies, which I think I am most excited about, because we have a decent backbone of therapy at this point, but building on that and trying to maybe enhance the way that the backbone therapy works, and also to perhaps change the microenvironment of the bone marrow – basically, trying to reverse fibrosis.

So, there is currently a drug in clinical trial that is looking at this, and we are proceeding with this trial, and really hoping for the best, but I think that to combination therapies where we can put two things together that we think work really well together to help produce good outcomes – I think I’m most excited about that at this point.

Lindsey:

When deciding about a treatment, it’s really important for the healthcare professional and the patient to discuss the patient’s goals.

The patient really is the key player here, and we as medical professionals are here to support the patient’s goals. So, what might work for one patient is not going to be necessarily the same treatment I would choose for a different patient. So, right off the bat, identifying the patient’s goals – and really, what are we trying to fix in one specific patient is going to look different from the next patient I see in that day.

For example, there are certain clinical manifestations of MPNs that need specific treatment approaches and maybe honing in on trying to help one clinical issue.

So, first of all, identifying the disease process – that’s No. 1. What is the diagnosis? No. 2: Coming up with a goals of care plan with the patient. What is causing them the most difficulty in their everyday life, and how are we going to fix that? That’s generally where I start.

Then, I discuss with the patients the different options for treatment, which either include therapies that are FDA-approved or enrolling in a clinical trial. And then, we really talk about pluses and minuses for each of these therapeutic decisions.

Patients may have different comorbidities, so they may suffer from different chronic diseases that may impact the treatment that is chosen with the patient and their provider, as well as discussing stem cell transplant, which we haven’t talked much about, but stem cell transplant is an option, and at this point, the only curative therapy for patients with myelofibrosis. And so, determining whether or not transplant is in the patient’s best interest is also a topic of discussion when deciding on therapy approach.

Understanding Clinical Trials: A Jargon Buster Guide

When it comes to cancer treatment you or a loved one may be considering participating in a clinical trial as a treatment option.  Clinical trials are designed to evaluate the safety and effectiveness of a treatment. They may involve researchers administering drugs, taking blood or tissue samples, or checking the progress of patients as they take a treatment according to a study’s protocol.

Learning about clinical trials can be a steep learning curve – not least because the process comes with a lot of new terms, acronyms and jargon.  To help you, I’ve put together this list of the most common terms you will find when you are researching clinical trial information. This is not an exhaustive list but it is a helpful starting point. At the end of this article you will see links to find more information.

Adverse Effects (AE)

Also called Adverse Events, or Adverse Drug Reaction, AEs are any harmful event experienced by a person while they are having a drug or any other treatment or intervention. In clinical trials, researchers must always report adverse events, regardless of whether or not the event is suspected to be related to or caused by the drug, treatment or intervention.

Arm

Subsection of people within a study who have a particular intervention.

Bias

Bias is an error that distorts the objectivity of a study. It can arise if a researcher doesn’t adhere to rigorous standards in designing the study, selecting the subjects, administering the treatments, analysing the data, or reporting and interpreting the study results. It can also result from circumstances beyond a researcher’s control, as when there is an uneven distribution of some characteristic between groups as a result of randomization.

Blinding

Blinding is a method of controlling for bias in a study by ensuring that those involved are unable to tell if they are in an intervention or control group so they cannot influence the results. In a single-blind study, patients do not know whether they are receiving the active drug or a placebo. In a double-blind study, neither the patients nor the persons administering the treatments know which patients are receiving the active drug. In a triple-blind study, the patients, clinicians/researchers and the persons evaluating the results do not know which treatment patients had. Whenever blinding is used, there will always be a method in which the treatment can be unblinded in the event that information is required for safety.

Comparator

When a treatment for a specific medical condition already exists, it would be unethical to do a randomized controlled trial that would require some participants to be given an ineffective substitute. In this case, new treatments are tested against the best existing treatment, (i.e. a comparator). The comparator can also be no intervention (for example, best supportive care).

Completed

A trial is considered completed when trial participants are no longer being examined or treated (i.e. no longer in follow-up); the database has been ‘locked’ and records have been archived.

Control

A group of people in a study who do not have the intervention or test being studied. Instead, they may have the standard intervention (sometimes called ‘usual care’) or a dummy intervention (placebo). The results for the control group are compared with those for a group having the intervention being tested. The aim is to check for any differences. The people in the control group should be as similar as possible to those in the intervention group, to make it as easy as possible to detect any effects due to the intervention.

Efficacy

How beneficial a treatment is under ideal conditions (for example, in a laboratory), compared with doing nothing or opting for another type of care. A drug passes efficacy trials if it is effective at the dose tested and against the illness for which it is prescribed.

Eligibility Criteria/ Inclusion and Exclusion Criteria

Eligibility criteria ensures patients enrolling in a clinical trial share similar characteristics (e.g. gender, age, medications, disease type and status) so that the results of the study are more likely due to the treatment received rather than other factors.

Follow-up

Observation over a period of time of participants enrolled in a trial to observe changes in health status.

Informed Consent

A process (by means of a written informed consent form) by which a participant voluntarily agrees to take part in a trial, having been informed of the possible benefits, risks and side effects associated with participating in the study.

Intervention

The treatment (e.g., a drug, surgical procedure, or diagnostic test) being researched. The intervention group consists of the study participants that have been randomly assigned to receive the treatment.

Investigator

A person responsible for the conduct of the clinical trial at a trial site. If a trial is conducted by a team of individuals at a trial site, the investigator is the responsible leader of the team and may be called the principal investigator (PI).

Multicentre Trial

A clinical trial conducted according to a single protocol but at more than one site, and therefore, carried out by more than one investigator.

Number needed to treat (NNT)

The average number of patients who need to receive the treatment or other intervention for one of them to get the positive outcome in the time specified.

Outcome Measures

The impact that a test, treatment, or other intervention has on a person, group or population.

Phase I, II, III and IV Studies

Once the safety of a new drug has been demonstrated in tests on animals, it goes through a multi-phase testing process to determine its safety and efficacy in treating human patients. If a drug shows success in one phase, the evaluation moves to the next phase

  • Phase 1 tests a drug on a very small number of healthy volunteers to establish overall safety, identify side effects, and determine the dose levels that are safe and tolerable for humans.
  • Phase II trials test a drug on a small number of people who have the condition the drug is designed to treat. These trials are done to establish what dose range is most effective, and to observe any safety concerns that might arise.
  • Phase III trials test a drug on a large number of people who have the condition the drug is designed to treat. Successful completion of Phase III is the point where the drug is considered ready to be marketed.
  • Phase IV trials can investigate uses of the drug for other conditions, on a broader patient base or for longer term use.

Placebo

A fake (or dummy) treatment given to patients in the control group of a clinical trial.  Placebos are indistinguishable from the actual treatment and used so that the subjects in the control group are unable to tell who is receiving the active drug or treatment. Using placebos prevents bias in judging the effects of the medical intervention being tested.

Population

A group of people with a common link, such as the same medical condition or living in the same area or sharing the same characteristics. The population for a clinical trial is all the people the test or treatment is designed to help.

Protocol

A plan or set of steps that defines how something will be done. Before carrying out a research study, for example, the research protocol sets out what question is to be answered and how information will be collected and analysed.

Randomized Controlled Trial (RCT)

A study in which a number of similar people are randomly assigned to 2 (or more) groups to test a specific drug, treatment or other intervention. One group has the intervention being tested; the other (the comparison or control group) has an alternative intervention, a placebo, or no intervention at all. Participants are assigned to different groups without taking any similarities or differences between them into account. For example, it could involve using a computer-generated random sequence. RCTs are considered the most unbiased way of assessing the outcome of an intervention because each individual has the same chance of having the intervention.

Reliability

The ability to get the same or similar result each time a study is repeated with a different population or group.

Sample

People in a study recruited from part of the study’s target population. If they are recruited in an unbiased way, the results from the sample can be generalised to the target population as a whole.

Subjects

In clinical trials, the people selected to take part are called subjects. The term applies to both those participants receiving the treatment being investigated and to those receiving a placebo or alternate treatment.

Trial Site

The location where trial-related activities are conducted.
