"The results from both the SIMPLIFY-1 and SIMPLIFY-2 studies indicate that momelotinib provides some treatment benefit, including benefit on anemia-related endpoints," said Norbert Bischofberger, PhD, Executive Vice President of Research and Development and Chief Scientific Officer. "We plan to discuss these results with regulatory authorities to determine the next steps."Detailed results from both studies will be submitted for presentation at upcoming scientific conferences. Momelotinib is an investigational therapy and has not been proven safe or efficacious. About the SIMPLIFY Studies The SIMPLIFY studies were randomized, Phase 3 clinical trials designed to evaluate momelotinib among patients with primary myelofibrosis, post-polycythemia vera myelofibrosis or post-essential thrombocythemia myelofibrosis. In SIMPLIFY-1, a double-blind, active-controlled study, 432 myelofibrosis patients who had not previously been treated with a JAK inhibitor were randomized (1:1) to receive momelotinib or ruxolitinib for 24 weeks. In SIMPLIFY-2, 156 patients previously treated with, but not refractory to, ruxolitinib were randomized (2:1) to receive momelotinib or BAT for 24 weeks. The primary efficacy endpoint of both studies was SRR24, defined as the proportion of patients achieving a = 35 percent reduction in spleen volume at Week 24 as measured by magnetic resonance imaging (MRI) or computerized tomography (CT) scan. Secondary endpoints included response rate in TSS at Week 24 (the proportion of patients achieving = 50 percent reduction in symptoms, as measured by the modified Myeloproliferative Neoplasm Symptom Assessment Form Total Symptom Score diary), the proportion of patients who are transfusion-independent at Week 24 (defined as no red blood cell transfusion and no hemoglobin level below 8 g/dL in the prior 12 weeks); the proportion who are transfusion-dependent at Week 24 (defined as at least four units of red blood cell transfusion or hemoglobin level below 8 g/dL in the prior eight weeks), and the rate of red blood cell transfusion through Week 24.
