A Study of Fedratinib in Japanese 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)

Plain-language summary
The study will be conducted in compliance with the International Council for Harmonisation (ICH) of Technical Requirements for Registration of Pharmaceuticals for Human Use/Good Clinical Practice (GCP) and applicable regulatory requirements.
This is a Phase 1/2 multicenter, single arm, open-label study in Japanese subjects with DIPSS intermediate or high-risk PMF, post-PV or post-ET MF. The study consists of 2 parts: Phase 1 part to determine safety and tolerability and a RP2D. The Phase 1 portion of the study will explore one or more drug doses for fedratinib (300 mg and 400 mg) using a mTPI-2 design. Following completion of dose escalation and determination of MTD and/or a RP2D, the study will progress into the Phase 2 part to further evaluate the efficacy and safety.
The study will consist of 3 periods: a Screening Period, a Treatment Period including a 30-day follow-up after last dose visit and a survival follow-up period.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
. Subject must meet at least one of the following criteria of (a or b).
. Previously received ruxolitinib treatment for PMF or post-PV MF or post-ET MF for at least 14 days (exposure of \< 14 days is allowed for subjects who discontinued ruxolitinib due to intolerability or allergy).
. Never received ruxolitinib treatment and is expected to derive clinical benefit from this study participation based on the clinical judgement of the Investigator Only those subjects who previously received ruxolitinib treatment are eligible for the Phase 1 part of the study to avoid overestimating tolerability of fedratinib.
Exclusion criteria
. Any of the following laboratory abnormalities:
. Platelets \< 50 x 109/L (without platelet transfusion)
