Pacritinib For Bone Marrow Fibrosis In Patients With Myelofibrosis Who Have Thrombocytopenia

Tests Pacritinib

For Myelofibrosis,MF

We hypothesize that pacritinib leads to modification of the myelofibrosis (MF) disease phenotype, especially related to BM fibrosis and cytopenias; due potentially to its dual effect as an inhibitor of the JAK and NFκB pathways, through its targets JAK2 and IRAK1 respectively, leading to a decrease of inflammatory cytokines and/or effects on stem/progenitor populations restoring hematopoiesis New evidence suggests that blocking simultaneously the JAK/STAT and NF-κB pathways might have a beneficial effect on aspects that only inhibition of the JAK pathway cannot achieve: partial recovery of BM histology and PACRIMYEL is a multicenter, open-label, single arm, phase II, exploratory study including patients with MF and platelet count between 50 - 120 x 109/L. Clinic visits will occur on weeks 4, 8, 12, 24, 36 and 52 during the first year and every 12 weeks during the second year of the treatment, and pacritinib will be dispensed at every visit to the clinic. Bone fibrosis will be assessed by biopsy and MRI imaging \[mDixon Quant "(Philips), IDEAL IQ (General Electric) or qDixon (Siemens)\] on weeks 24 and 52 after the first dose of study treatment. Splenomegaly and SVR (Splenic Volume Reduction) will be assessed by physical exam and MRI imaging on weeks 24 and 52 after the first dose of study treatment if splenomegaly at diagnosis. Same MRI to evaluate BM imaging will be used to measure spleen volume. Additionally, spleen size will be assessed by physical exam during the routine clinic visits. All patients should complete all efficacy assessments through Week 52, including patients who stop study treatment or have protocol-defined progressive disease prior to Week 24 and 52, unless the patient withdraws consent or dies. For patients who discontinue treatment before disease assessments on week 24 and week 52 for other reasons different than protocol-based progression of the disease (i.e. toxicity), and with no recent disease / fibrosis assessment (last BM biopsy \> 12 weeks), disease and fibrosis assessments will be performed by the end of treatment visit. The trial includes the assessment of safety (AEs, comorbidities) throughout the study period at every visit. Patient-reported symptoms through MPN-SAF TSS 2.0 will be collected screening, baseline (C1D1), and on Week 12, Week 24, Week 36, Week 52 and in 12-weeks intervals during the second year. Blood samples for translational research will be collected at screening and at week 24 for determination of cytokines.

MPN PROGRESSion Registry: Observational Study Tracking Symptoms, Treatments, and Disease Progression in People With Myeloproliferative Neoplasms (MPNs)

For Polycythemia Vera, ET (Essential Thrombocythemia), Polycythemia Vera (PV), Essential Thrombocythemia (ET) and Primary Myelofibrosis (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 help identify patterns and predictors of disease progression, treatment response, quality of life, and long-term outcomes. These insights are intended to guide future research, inform clinical guidelines, and support improvements in patient care. The registry is non-interventional and observational; participants do not receive investigational treatments, and all medical care continues under the supervision of their own physicians. Data collection includes EHRs, PRO surveys, patient-reported symptom and lab tracking, insurance claims, and, in the future, may include linkages with other relevant disease registries and datasets. Potential collaborations under consideration include those with the European LeukemiaNet (ELN) MPN Registry, the Mayo Clinic MPN Database, the Center for International Blood and Marrow Transplant Research (CIBMTR), the SEER Program, Harmony Alliance Foundation, and the National Cancer Database (NCDB). The registry emphasizes the patient voice, incorporating lived experiences related to hallmark MPN symptoms such as fatigue, pruritus (itching), bone pain, night sweats, and social and emotional impacts. Participants will be followed for at least five years, with many enrolled for ten years or longer, to capture the natural history of disease and long-term outcomes. PRO surveys will be completed approximately every six months, and EHR data will be regularly reviewed to track changes in clinical status, treatment, and disease evolution. Statistical analyses will use descriptive and inferential methods to examine clinical characteristics, symptom burden, disease trajectories, and patient-centered outcomes. Planned subgroup analyses may compare differences across diagnoses, treatment approaches, demographics, or genomic factors. Analytic plans will be finalized during the course of the study and may evolve in response to emerging scientific questions. The registry is open to adults (18 years or older) living in the United States who have been diagnosed with any of the included MPN subtypes and are willing to share health information and complete study surveys. Individuals currently enrolled in interventional clinical trials or unable to provide informed consent may be excluded. Participation is voluntary, and participants may withdraw from the study at any time without affecting their medical care. Privacy and data security are core priorities. Participant data will be securely stored and managed in accordance with all applicable privacy laws and research regulations. No identifiable information will be shared with external parties without appropriate authorization. Oversight is provided by a Steering Committee and a Patient Engagement Advisory Committee (PEAC), ensuring rigorous scientific, ethical, and patient-centered governance. The registry is sponsored by the MPN Research Foundation, a nonprofit organization advancing research and patient advocacy in myeloproliferative neoplasms (MPNs). Participants can contact the registry team at any time with questions and will receive periodic updates on study findings. This study aims to address critical gaps in understanding the real-world experiences of people with MPNs-such as symptom burden over time, risk factors for progression, and how different treatments impact patient outcomes. Findings may inform clinical trial design, support biomarker discovery, and contribute to the development of updated treatment recommendations. The registry is committed to including participants from diverse backgrounds and clinical settings to ensure findings are broadly applicable across the MPN community. Summary results will be shared through scientific publications, presentations, and other dissemination efforts to advance MPN research and care globally.
