Detailed Summary:
Sponsor: Novartis Pharmaceuticals

Current Primary Outcome: Efficacy of ruxolitinib to Best Available Therapy (BAT) as assessed by Hct control at Week 28 [ Time Frame: Week 28 ]

Proportion of patients achieving Hct control at Week 28 as defined by: •Hct < 45% at Week 16 and maintained until Week 28, and •No phlebotomy from Week 4 to Week 28, with no more than one phlebotomy occurring post randomization and prior to the Week 4 visit.

    Change from Baseline in spleen length at each scheduled visit
  • Efficacy of ruxolitinib to BAT as assessed by partial remission based on the ELN and IWG-MRT criteria at Week 28 [ Time Frame: Week 28 ]
    Proportion of patients achieving a partial remission at Week 28, based on the ELN and IWG-MRT criteria, as defined by: •MPN-SAF TSS score reduction of greater than or equal to 10 points from baseline to Week 16 and maintained until Week 28 (for patients with a baseline score of 20 or more), and •Hct < 45% at Week 16 and maintained until Week 28, and •No phlebotomy from Week 4 to Week 28, with no more than one phlebotomy occurring post randomization and prior to the Week 4 visit, and •WBC < 10 x10E9/L at Week 16 and maintained until Week 28, and •Platelets ≤ 400 x 10E9/L at Week 16 and maintained until Week 28, and •No palpable spleen at Week 16 and maintained until Week 28, and •No hemorrhagic or thrombotic events, and •No transformation into post-PV myelofibrosis, myelodysplastic syndrome, or acute leukemia
  • Efficacy of ruxolitinib to BAT as assessed by durable partial remission based on the ELN and IWG-MRT criteria at Week 52. [ Time Frame: Week 52 ]
    Proportion of patients who achieved partial remission at Week 52, based on the ELN and IWG-MRT criteria, as defined by: •MPN-SAF TSS score reduction of greater than or equal to 10 points from baseline to Week 16 and maintained until Week 52 (for patients with a baseline score of 20 or more), and •Hct < 45% at Week 16 and maintained until Week 52, and •No phlebotomy from Week 4 to Week 52, with no more than one phlebotomy occurring post randomization and prior to the Week 4 visit, and •WBC < 10 x10E9/L at Week 16 and maintained until Week 52, and •Platelets ≤ 400 x 10E9/L at Week 16 and maintained until Week 52, and •No palpable spleen at Week 16 and maintained until Week 52, and •No hemorrhagic or thrombotic events, and •No transformation into post-PV myelofibrosis, myelodysplastic syndrome (IWG-MRT criteria) or acute leukemia (WHO criteria), and •In the BAT arm, no change in the treatment regimen or crossover to the ruxolitinib arm.
