A Commitment to New Therapies for MPN Despite Scientific Challenges

A researcher discussed the evolving understanding of myeloproliferative neoplasms (MPNs), from their initial classification to their potential for progression, and emphasized the scientific community's commitment to developing new therapies despite the inherent challenges of research.

John Crispino, director of the division of experimental hematology at St. Jude Children’s Research Hospital in Memphis, Tennessee, was recognized at the CURE MPN Heroes event for his dedication to the community both through his scientific breakthroughs and his advisory role for the MPN Research Foundation.

CURE also spoke with Crispino about what he has learned about patients with MPNs and the research around the condition over his years in the field. One of the things he mentioned was the disease’s transition from a myeloproliferative disorder to a myeloproliferative neoplasm. In particular, the World Health Organization (WHO) changed the classification of these conditions to MPNs to reflect the understanding that these conditions are a type of cancer.

So MPNs is a — you know, actually, when I first started this field, … it's a chronic disease, but it was considered nonmalignant, and then there was a change from MPD [myeloproliferative disorder] to MPN. So it's a neoplastic disease, clearly, and has this high propensity to evolve from, let's say, PV [polycythemia vera] or ET [essential thrombocythemia] to MF [myelofibrosis], and then MF to acute leukemia.

And so I've done a fair amount of work with the patient population through my MPN Research [Foundation] association or affiliation, and I feel for these patients, and I want them to understand that there are many of us who are working diligently to develop new therapies.

It's just, I would say that science is — doesn't always go the way you want. You know, some experiments just don't pan out. Drugs that we develop in the laboratory just sometimes don't work in people, and that's unfortunate, but I ask for patients, and again, [to] know that we are committed to this.
