What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

Phase 1 is the earliest stage of human testing — safety and dosage are the primary focus. Visits are frequent and medical supervision is intensive. You will be among the first people to receive this treatment.

This trial targets 240 participants in total. It began in 2019-12-16 with a primary completion date of 2027-04-30.

Brief Summary

This study is a Phase 1/2, multicenter, dose-escalation, open-label trial to assess safety, tolerability, pharmacokinetics and pharmacodynamics of nuvisertib (TP-3654) in patients with intermediate or high-risk primary or secondary MF.
