Post-polycythemia Vera Myelofibrosis (Post-PV MF)

The MPN PROGRESSion Registry is a multi-year, observational research study designed to improve understanding of myeloproliferative neoplasms (MPNs)-a group of rare, chronic blood cancers that include polycythemia vera (PV), essential thrombocythemia (ET), primary myelofibrosis (MF), pre-fibrotic primary myelofibrosis (pre-PMF), secondary myelofibrosis, myeloproliferative neoplasm-unclassifiable (MPN-U), MPN in accelerated phase (MPN-AP), and MPN in blast phase (MPN-BP), post-MPN Acute Myeloid Leukemia (AML), and MDS/MPN overlap syndrome as defined above per WHO 2022 criteria, including patients originally diagnosed with one of these conditions but who have received one or more SCTs and/or BMTs . These conditions are characterized by abnormal blood cell production in the bone marrow and may lead to complications such as blood clots, bleeding, bone marrow fibrosis, and, in some cases, progression to acute leukemia. The central hypothesis of the registry is that collecting and analyzing real-world, longitudinal data-including electronic health records (EHRs), laboratory values, treatments, and patient-reported outcomes (PROs)-from a diverse population of people living with MPNs will
