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 of spleen volume and one of the secondary objectives is to evaluate the safety of fedratinib

Experimental: Administration of Fedratinib 400mg/day
Self-administered Investigational Product (IP) (400 mg/day) on an outpatient basis, once daily preferably with food during an evening meal at the same time each day in consecutive 4-week (28-day) cycles.
A potent and selective inhibitor of JAK2 kinase activity
- Proportion of subjects who have a ≥ 35% SVR at end of Cycle 6 [ Time Frame: At the end of Cycle 6 (each cycle is 28 days) ]Spleen volume response rate (RR)
- Adverse Event(s) [ Time Frame: Up to 12 months post last dose ]Number of participants with adverse event
- Proportion of subjects who have ≥ 50% reduction in spleen size by [ Time Frame: At the end of Cycle 6 (each cycle is 28 days) ]Spleen response rate by palpation (RRP)
- Symptom response rate (SRR) [ Time Frame: At the end of Cycle 6 (each cycle is 28 days) ]Is defined as the proportion of subjects with ≥ 50% reduction from baseline to the end of Cycle 6 in total symptom score (TSS) measured by MFSAF version 4.0.
- To evaluate durability of spleen volume response (DR) [ Time Frame: From enrollment until treatment discontinuation (estimation of 12 months) ]Is defined as time from the first documented spleen response (ie, ≥ 35% reduction in spleen volume) to the first documented spleen volume reduction < 35%.
- To evaluate the durability of spleen response by palpation (DRP) [ Time Frame: From enrollment until treatment discontinuation (estimation of 12 months) ]Is defined as time from the first documented palpable spleen response, according to the IWG-MRT 2013 to the time of the first documented loss of response according to the IWG-MRT 2013.
- Durability of symptoms response (DSR) [ Time Frame: Up to 30 days post last dose ]Is defined as time from the first documented response in TSS (ie, reduction in TSS ≥ 50%) measured by MFSAF version 4.0 to the first documented TSS reduction < 50%.
- Gastrointestinal Adverse Events [ Time Frame: Up to 30 days post last dose ]Incidence of subjects with Grade 3 or higher Gastrointestinal events (nausea, diarrhea, or vomiting) according to CTCAE v5.0
- Wernicke encephalopathy (WE) events [ Time Frame: Up to 30 days post last dose ]Occurrence of confirmed Wernicke encephalopathy events
- Wernicke encephalopathy (WE) thiamine monitoring [ Time Frame: Up to 30 days post last dose ]Monitoring and correction of thiamine levels as appropriate
