Study Summary

The purpose of this Phase 3 study is to evaluate the efficacy and safety of Luspatercept compared with placebo in subjects with myeloproliferative neoplasm (MPN)-associated Myelofibrosis (MF) and anemia on concomitant Janus kinase 2 (JAK2) inhibitor therapy and who require red blood cell count (RBC) transfusions. The study is divided into Screening Period, a Treatment Phase (consisting of a Blinded Core Treatment Period, a Day 169 Response Assessment, a Blinded Extension Treatment Period, and an Open-label Extension Treatment Period), and a Posttreatment Follow-up Period. Following the Day 169 Response Assessment, subjects who did not show clinical benefit will have the option to unblind. Subjects who were on placebo during the Blinded Core Treatment Period will have the opportunity to crossover into the Open-Label Extension Treatment Period and receive Luspatercept.

Primary Outcome

Percentage of participants who become RBC-transfusion free over any consecutive 12-week period starting in first 24 weeks.
