Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Part 1: Safety/tolerability of ruxolitinib in combination with chemotherapy as measured by adverse events (AEs), vital signs, clinical laboratory tests, and echocardiograms		Part 1: AEs assessed from screening through up to 30 days after the last dose of study drug, expected to be 26 months (females) or 38 months (males)
Primary	Part 2: Efficacy of ruxolitinib in combination with chemotherapy as measured by Event-free survival, defined as the percentage of patients alive without relapse, progression, or death at 3 years from study Day 1		Part 2: assessed at 3 years
Secondary	Safety and tolerability of the combination treatment for subjects beginning treatment at the recommended dose for Part 2, as assessed by AEs, vital signs, clinical laboratory tests, and echocardiograms		AEs assessed from screening through up to 30 days after the last dose of study treatment, expected to be 26 months (females) or 38 months (males)
