Dr. Amanam, can you speak to any exciting new developments in MPN care or trials that you see moving forward with great progress?

Dr. Indoroenyi Amanam:

Yeah. I think for MPNs and namely really the classic BCR-able or Philadelphia chromosome-negative MPNs, which include essential thrombocythemia, polycythemia vera, and myelofibrosis. I think we have a lot of exciting therapies that are going to be possibly FDA-approved in the next couple of years. So currently, for essential thrombocythemia, really the dogma therapy is related to keeping the counts under control and giving a therapy to reduce the risk of having a blood clot or stroke. We actually are in a space where we have therapies that are going to be targeting the underlying clone or basically the cells that are driving the proliferation of these platelets that lead to high platelet counts. And so I think that’s exciting.

So we do know that, in MPN there is an overexpression of Bcl-xL, and there’s a drug that targets Bcl-xL. And we’ve seen really great responses in essential thrombocythemia. And as a segue, this drug also targets the same cells and polycythemia vera and myelofibrosis, and we’ve seen really great responses in those patients. We also have had difficulty in managing patients who have myelofibrosis, but have very low counts. And typically the FDA-approved drugs that we’ve been using actually make the counts worse.

And so there are multiple drugs that are in the pipeline that are helping patients with low blood counts. And what they do is they help increase your red blood cells and reduce your requirements for red blood cell transfusions.

And one of the drugs helps stimulate erythropoiesis, and it’s an injection. And we’ve seen really good results in reducing the risk of…or reducing the amount of transfusions that patients receive. And then another one of these drugs targets ACVR1, which we understand that in myelofibrosis, you have overproduction of hepcidin, which leads to worsening anemia. And so by targeting ACVR1, it helps control this hepcidin. And by doing that these patients have improved red blood cell counts. And so that’s another drug that likely will be coming…that will be FDA-approved very soon, and I think will help patients in this space.

We also are interested in immunotherapy. And I think in other cancers, immunotherapy has been very successful in eradicating those cancer cells and curing some patients. And so there are clinical trials looking at a vaccine which targets certain mutations that are relevant to MPN patients. And also we are interested in actually using other types of immunotherapy namely, CAR T, which really helps connect your own immune cells to these cancer cells to help clear them out. And so I think over in the next five to 10 years, there’re going to be a lot of drugs and a lot of therapies that are going to really help patients who have MPNs.

Lisa Hatfield:

Dr. Amanam, what promising treatments are available for newly diagnosed MPN patients, and what questions should patients be asking? They come into your office scared to death and not even knowing what to ask. Do you have any suggestions for what those patients should be asking when they go in as a newly diagnosed patient?

Dr. Indoroenyi Amanam:

Right, right. Twenty years ago, we really didn’t have any therapies for most MPN patients, aside from performing phlebotomy and using non-specific therapies to try to help control their counts and therefore reduce their risk of clotting and stroke. We are getting to a point which is really exciting, where we actually are treating the underlying disease, meaning that the cells that are causing this cancer, we have been able to identify targets that will help eradicate those cells and, therefore, get rid of the cancer. And so we’re getting there. Unfortunately, we still are not there yet, and so when we look at the FDA-approved drugs in this space, really, they help control symptoms, they help control some of the associated complications with the disease, mainly when your spleen’s enlarged, and that potentially may affect your quality of life, mainly your nutritional status and your physical status, and so we do have drugs that are able to do that, that are FDA-approved right now.

I think in the next three to five years, we’re going to have drugs that are going to actually be able to treat the underlying disease before it gets to a point where you may need more aggressive therapy. Currently, the only defined curative therapy that we have, when I say defined, meaning that we have multiple studies that have shown that that’s the case, is bone marrow transplant. I’m a bone marrow transplanter, I do treat some of my MPN patients with bone marrow transplant to get rid of the underlying…those underlying cells that are driving this disease. But that’s a very intense therapy and it has its own associated complications. But we are…will be having other drugs that potentially we would be able to offer that are not as intense as bone marrow transplant.

And those include immunotherapy, other drugs that can target the signals that drive these cells to divide and multiply. Also there are within the bone marrow for patients that have myelofibrosis, which is one of the MPNs, we will be able to target the environment that allows for these cells to persist and grow. And so it’s exciting where we’re going, and I think the questions that as a patient that I would ask are, because of the fact that we only have few FDA-approved therapies, are there any clinical trials that are able to target the underlying disease as opposed to just treating the symptoms? I think that’s very important for the patients to ask, especially in this space now.

Are MPN Risks and Outcomes Impacted by Race or Ethnicity? from Patient Empowerment Network on Vimeo.

Are myeloproliferative neoplasm (MPN) risks and outcomes impacted by patient race or ethnicity? Expert Dr. Idoroenyi Amanam from City of Hope explains common MPN symptoms, potential risks and outcomes, and patient advice for optimal care.

[ACT]IVATION TIP:

“…if you have stroke, heart attack, blood clots, abnormal counts, please follow up with your doctor and ensure that you get referred to the appropriate specialist to help assist in managing your complications.”

MPN-Related Complications | Are BIPOC Patients at Higher Risk

Transcript:

Lisa Hatfield:

Dr. Amanam, how does race impact clinical MPN outcomes or complications? And are certain populations more susceptible to getting MPNs?

Dr. Indoroenyi Amanam:

Yeah, it’s a great question. I think, because of the fact that symptoms are not as clearly related to MPNs as opposed to some other diseases. So the major presenting symptoms for MPNs are related to high blood pressure or some other vascular abnormality, including strokes or blood clots. It takes a little work to diagnose MPN patients, and half of them are asymptomatic. And if you actually look at diagnosis rates, they’re one to three cases per 100,000 per year. And so this is very rare, and I think that we don’t have enough data to really understand if some groups are at higher risk to develop MPNs than others.

We have looked at incidences of thrombotic events in patients who have MPNs, and we tried to see if there was a difference between racial groups, and we didn’t. We did see that if you’re younger, you do have a higher risk of thrombosis over time, but there was no difference for if you were white, Hispanic, or African American.

What we did find though, in a small single center study is that if you are non-white, there’s a higher risk of death over time. And I think we still need a lot of work to get a better understanding as why that’s the case. So far we don’t have a clear signal for that, but I do think, in the same…the story that we understand for healthcare in general, there are some differences in terms of access to care, the quality of care that’s delivered in, you can guess that possibly that’s one of the reasons why that that affects African Americans and Hispanics disproportionately in this setting as well.

So my activation tip for this question would be if you have stroke, heart attack, blood clots, abnormal counts, please follow up with your doctor and ensure that you get referred to the appropriate specialist to help assist in managing your complications.
