A Phase 2, Open-label, Translational Biology Study of Momelotinib in Transfusion-Dependent Subjects With Primary Myelofibrosis (PMF) or Post-polycythemia Vera or Post-essential Thrombocythemia Myelofibrosis (Post-PV/ET MF)
Description
Brief Summary
This study will evaluate the transfusion independence response rate in transfusion-dependent
adults with myelofibrosis after treatment with momelotinib (MMB).
Phase
Phase 2 - takes the treatment one step further, assessing the activity of a particular therapy in a disease, often building upon leads from the Phase I trial. While patients are generally required to be previously untreated, participation in a Phase II trial doesn't usually preclude the patient from getting the standard treatment after they've received the investigational agent. At best they are allowed to get a new drug they wouldn't be able to get otherwise that may turn out to be better for their disease.Inclusion and Exclusion Criteria
- Diagnosis of PMF or Post PV/ET-MF
