Efficacy of Momelotinib in Myelofibrosis Patients: Results From a Multicenter Study.

ABSTRACT: Momelotinib, a novel JAK1/2 inhibitor with inhibitory activities on activin A receptor type I, has shown breakthrough clinical efficacy in patients with myelofibrosis (MF) and anemia, a disease-related manifestation of challenging management. In this retrospective real-life multicenter Italian study, we investigated the safety and efficacy of momelotinib in a cohort of 39 consecutive MF patients, regardless of prior therapy. The median duration of treatment was 7 months, and the overall response rate was 56% in transfusion-dependent patients and 46% in the transfusion-independent group. At 24 weeks of treatment, a hemoglobin increase > 1.5 g/dL was observed in 26% of patients, and constitutional symptom improvement was reported in 51% of cases, with a spleen volume reduction > 35% in 28%.
