Efficacy and safety of fedratinib in patients with myelofibrosis previously treated with ruxolitinib (FREEDOM2): results from a multicentre, open-label, randomised, controlled, phase 3 trial

Most patients with myelofibrosis develop ruxolitinib intolerance or disease that is relapsed or refractory, and survival rates after ruxolitinib discontinuation are poor. We aimed to evaluate the safety and efficacy of fedratinib versus best available therapy (BAT) in patients with myelofibrosis previously treated with ruxolitinib.
