Brief summary:
This is Single-Arm, Open-Label Efficacy and Safety Trial of Fedratinib in Subjects with DIPSS (Dynamic International Prognostic Scoring System)-Intermediate or High- Risk Primary Myelofibrosis (PMF), Post-Polycythemia Vera Myelofibrosis (post-PV MF), or Post-Essential Thrombocythemia Myelofibrosis (post-ET MF) and Previously Treated with Ruxolitinib. The primary objective of the study is to evaluate the percentage of subjects with at least a 35% reduction in spleen size and one of the secondary objectives is to evaluate the safety of fedratinib.
This is Single-Arm, Open-Label Efficacy and Safety Trial of Fedratinib in Subjects with DIPSS (Dynamic International Prognostic Scoring System)-Intermediate or High- Risk Primary Myelofibrosis (PMF), Post-Polycythemia Vera Myelofibrosis (post-PV MF), or Post-Essential Thrombocythemia Myelofibrosis (post-ET MF) and Previously Treated with Ruxolitinib. The spleen volume reduction at the end of Cycle 6 as the primary objective. The secondary objectives of the study are to further evaluate the safety and to assess and implement mitigation strategies for WE and for gastrointestinal (GI) adverse events. The study will be at multiple centers to provide access to a broad population and have assurance the results are likely to have general applicability. This is also conducted as an open-label study to collect efficacy and safety data with fedratinib use, no randomization or stratification will occur.
