Options for MPN Treatment Are Expanding Rapidly With More on the Horizon

The past few years have been an exciting time in myeloproliferative neoplasms (MPNs) with new treatments providing new options for patients and additional products in the pipeline that explore new mechanisms of action, explained Firas El Chaer, MD, associate professor of medicine, University of Virginia School of Medicine. At the American Society of Hematology annual meeting, El Chaer had presented research and been a coauthor on abstracts related to treatment for myeloproliferative neoplasms.

He discussed how MPNs are diagnosed, the current treatment landscape, and promising new therapies in the pipeline. When diagnosing for MPNs, particularly for myelofibrosis, a bone marrow biopsy is needed, but the challenge is that this can be “patchy,” he explained, and the amount of fibrosis present in the particular part of the bone marrow that is biopsied is what is relied upon to make the diagnosis.

The good news is that the approval of many new Janus kinase inhibitors has changed the treatment landscape of myelofibrosis dramatically in the last few years, El Chaer said, which has provided patients with additional options for treatment. In addition, there are new mechanisms of action that can improve anemia in this patient population.

“I’m very excited that currently we’re thinking about combination therapies,” he said, to improve anemia or that potentially have a disease-modifying capability. “Our field is expanding very quickly.”

He highlighted some of the new mechanisms of action being studied in myeloproliferative neoplasms, such as bromodomain molecules and TGF-β agonists, which can potentially be helpful for anemia and this patient population. He had presented phase 1/2 data on nuvisertib, or TP-3654, which is a highly selective PIM1 kinase inhibitor that has reduced spleen size and bone marrow fibrosis either alone or in combination with ruxolitinib. Nuvisertib has minimal cytopenia side effect and can be combined with other molecules for treatment. Currently, enrollment is ongoing in 3 arms of the study (NCT04176198) to continue to evaluate nuvisertib as a monotherapy and in combination with ruxolitinib and momelotinib.

Emerging Data Continue to Evolve Treatment Utilization in MPNs

Laura Joszt, MA

Emerging data are continually changing the knowledge base around how interferons should be used, despite being around for decades, in patients with myeloproliferative neoplasms (MPNs), says Raajit Rampal, MD, PhD, hematologic oncologist, associate attending physician, Memorial Sloan Kettering Cancer Center.

Transcript

How has the landscape for MPN treatment evolved since the introduction of interferons? How does it look different today?

I guess it’s more a question of utilization than the landscape, in the sense that both things like hydroxyurea and interferons and drugs, like an anagrelide for ET [essential thrombocythemia], have been around for quite some time. And I think that it hasn’t been clear for the majority of that time which drugs should be used when and by whom.

There is now randomized clinical trial data for pegylated interferon vs hydroxyurea, but more recently, particularly with regards to polycythemia vera, there’s randomized data with ropeginterferon and hydroxyurea. And at least in that data set, the [blood] count control was superior with ropeginterferon vs hydroxyurea over the course of a number of years. Initially, at 1 year, there wasn’t so much of a difference, but as time went on, there was clearly a difference that favored the use of ropeginterferon in terms of controlling the blood counts. Similarly, over time, there does seem to be a decrease in the JAK [Janus kinase] 2 mutation burden in the patients who got the ropeginterferon.

I think that there is an emerging data set that is arguing that there are benefits to interferon. Going back to the initial point here, the landscape has changed to some degree—with the introduction of something like ropeginterferon—but I think it’s more that the data is evolving, which is beginning to tell us maybe which drugs might be best for which patients. We’re not completely there by any stretch of the imagination, but the data is beginning to coalesce around the message.

A Parent’s Story: Navigating the Health Insurance Maze

I know there are good people who work at insurance companies, however, some are the bane of my existence. Every month I gear up for the fight to get my son, Jedi, his medicine. Jedi has an MPN. My hope is that my journey can be used to make this process easier and better for other patients and their families.

Hydroxyurea was the initial drug prescribed for my son. It wasn’t a difficult drug to get filled, even though it was a little overwhelming walking my son through the adult oncology unit at MD Anderson Cancer Center, to the “specialty pharmacy.” It was frightening for him to see adults that look so sickly skinny and with their bald heads from their treatments. However, the real frustration began when he was put on Pegasys. MD Anderson tried to call numerous pharmacies to his prescription filled, but they were unable to find a pharmacy that had it in stock. So we left the hospital with a handwritten script in search of the drug.

At that time, we were insured by United Health Care. This was my first introduction to a specialty drug. For background purposes, specialty drugs are a recent designation of pharmaceuticals that are classified as high-cost, high complexity and/or high touch, such as injectables. A chemotherapy that is administered orally, like Hydroxyurea, is covered as part of a normal prescription. A chemotherapy that is administered as a subcutaneous (jiggly fat) shot, like Pegasys, is not. In other words, it comes out of your deductible. For us, that means we owed approximately $4,000 for the first month of Pegasys. We had to prove to the insurance company that Pegasys had been approved for polycythemia vera. This was done by producing a memo my husband found on the internet from United Health Care specifically stating Pegasys was approved for polycythemia vera.

Then, our insurance was switched to Blue Cross Blue Shield of Texas (BCBSTX). (I will skip the conversation about trying to get our member number early so I could start the pre-approval process.  I had been told in a Facebook group that it took about six weeks to approve Pegasys with BCBS. This was cause for concern because we could only get four weeks of medicine at a time.)

I started the pre-approval process with BCBS after we received a member ID number the first week of January. As expected, Pegasys was initially declined.  In the state of Texas I should be able to submit an emergency appeal and get a response in three days, but I had to get the appeal submitted first.  It is very difficult to get the appeal started. Not to mention that BCBSTX outsources the pharmaceuticals to Prime.

After a few weeks of deep frustration and the looming possibility we could run out of his medication, I finally posted the following on Blue Cross Blue Shield of Texas Facebook page:

January 15, 2019. Your appeals process is TERRIBLE. I have spent HOURS trying to figure this out. I have a 10 year old with CANCER. His medicine is out next week. I have to get it from a specialty pharmacy. His doctor called BCBS yesterday (a number I got after spending TWO HOURS on the phone last Friday) and was told that he has to wait 7-10 business days to start the process. Today I received a NEW peer-to-peer phone number. Does this start the process? No, it sets up an appointment for our doctor to talk to your doctors. Just to give you an idea. This medicine controls platelets. If his platelets go up he could have a heart attack, stroke, embolism for example. You can see my concern. My next steps are to ask my doctor to call AGAIN to START the appeals process – you know the one he tried to start yesterday? I will also have on my TO DO list to file a complaint with Texas Department of Insurance, contact my state Senator and Representative. Thank you for making this such a HARD process. Oh, by the way, the National Comprehensive Cancer Network, other BCBS insurance (different states), United Healthcare ALL have approved this medicine for his diagnosis

 I received a phone call from BCBSTX within 24 hours of posting this. I was told I had made it to the “special escalation” team because I posted on social media. On one hand, I am grateful he was approved. On the other hand, I am sad that this is what it took. I think it also helped that I had gathered the information to make it easy for them to approve. I had whitepapers, Jedi’s medical records and the details from the National Comprehensive Cancer Network. (Click here to view).

I wish I could say this was the end of the drama. But this is a story for another day. Just writing this was overwhelming. I can’t imagine what people who are sick go through. I am the caregiver, not the patient. I do not have chemo brain and I am exhausted by the process and the stress and anxiety to ensure my child receives his treatment. I hope this information will help other families move through the process a little more smoothly and I will continue to write about the trial and tribulations I experience on my website.
