A Study to Evaluate Safety and Efficacy of Selinexor in Combination With Ruxolitinib in Participants With Myelofibrosis
This is a global, Phase 1/2, multicenter, open-label study to evaluate the safety and efficacy of selinexor plus ruxolitinib in treatment naïve myelofibrosis (MF) participants. The study will be conducted in two phases: Phase 1a/1b and Phase 2. The Phase 1a of the study will be dose escalation (non-randomized dose finding study) to determine the maximum tolerated dose [MTD], recommended Phase 2 dose (RP2D), and evaluate safety and preliminary efficacy and will follow a standard 3+3 design. The Phase 1b of the study will be dose expansion (non-randomized efficacy exploration) at the determined RP2D to further assess the safety and preliminary efficacy at this dose level. The Phase 2 (randomized efficacy exploration) of the study will include MF participants who are treatment naïve randomized 1:1 to receive the combination therapy of selinexor and ruxolitinib versus (vs) ruxolitinib monotherapy.
