Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Proportion of subjects with >/= 50% reduction in total symptom score in each dose group, as measured by the modified The Myelofibrosis Symptom Assessment Form (MFSAF) v3.0 diary		Baseline and Week 12
Secondary	Proportion of subjects with >/= 35% reduction in spleen volume, and mean percent change in spleen volume		Baseline, Week 12 and Week 24
Secondary	Proportion of transfusion dependent subjects who exhibit changes in transfusion frequency over any 12 week period on study and proportion of transfusion independent subjects who exhibit changes in hemoglobin level		Baseline to Week 12; Week 13 to Week 24 through the end of study or study termination visit.
Secondary	Safety and tolerability of itacitinib as measured by adverse events.		Every 4-6 weeks through the end of study or early termination visit (approximately 33 weeks exclusive of the extension phase).
