Description

Summary

A Phase 3, randomized, blinded study comparing pelabresib (CPI-0610) and ruxolitinib with placebo and ruxolitinib in myelofibrosis (MF) patients that have not been previously treated with Janus kinase inhibitors (JAKi). Pelabresib is a small molecule inhibitor of bromodomain and extra-terminal (BET) proteins.
