Sierra Oncology Launches the MOMENTUM Phase 3 Clinical Trial for Patients with Myelofibrosis

Sierra Oncology announced today that it has launched the MOMENTUM clinical trial for patients with myelofibrosis. The randomized double-blind global Phase 3 trial is designed to confirm the efficacy of momelotinib on myelofibrosis symptoms, transfusion independence, and splenomegaly, as compared to danazol. The trial is targeting enrollment of 180 myelofibrosis patients who are symptomatic, anemic and have been treated previously with a JAK inhibitor.

According to Dr. Verstovsek "Momelotinib could become a suitable alternative for many patients previously treated with a JAK inhibitor due to its ability to positively address all three hallmarks of myelofibrosis - symptoms, anemia and an enlarged spleen. Critically, momelotinib has consistently demonstrated positive anemia benefits in its prior clinical trials. This anemia benefit is biologically-driven, via potent inhibition of the ACVR1/hepcidin axis, a mechanism that is unique in the JAK inhibitor class."

Momelotinib had previously been under Gilead before being sold to Sierra in 2018.
