Further study details as provided by Incyte Corporation:

Primary Outcome Measures:
  • 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 [ Time Frame: Baseline and Week 12 ]

Secondary Outcome Measures:
  • Proportion of subjects with >/= 35% reduction in spleen volume, and mean percent change in spleen volume [ Time Frame: Baseline, Week 12 and Week 24 ]
  • 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 [ Time Frame: Baseline to Week 12; Week 13 to Week 24 through the end of study or study termination visit. ]
  • Safety and tolerability of INCB039110 as measured by adverse events. [ Time Frame: Every 4-6 weeks through the end of study or early termination visit (approximately 33 weeks exclusive of the extension phase). ]
