France57 participantsStarted 2025-11-25
Plain-language summary
Multicenter, phase II trial with safety run-in to evaluate the efficacy and safety of momelotinib in patients with VEXAS (Vacuoles, E1 enzyme, X-linked, Autoinflammatory and Somatic) syndrome with or without associated myelodysplastic syndrome (MDS).
The study will consist of two consecutive steps, a dose-finding safety run-in and a single-arm prospective phase II.
During safety run-in phase, three fixed dose levels will be tested according to a 3+3 design, using cohorts of size 3 in order to establish the maximum tolerated dose.
After this safety run-in phase, patients included in phase II will be treated with momelotinib at the maximum tolerated dose preliminary fixed.
Patients included in the phase II will receive momelotinib continuously until disease progression or loss of response, at physician's discretion.
All patients included in the study will receive glucocorticoids (prednisone/prednisolone equivalent) at baseline (at least \> 10mg/day).
Response assessment regarding VEXAS related symptoms will be evaluated after 4, 12, 24 and 48 weeks. Response assessment regarding MDS features will be evaluated at 12 and 24 weeks.

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.
