  1. Study Design
  2. COMFORT-2

JAKAVI was studied in the most comprehensive clinical trial program in myelofibrosis to date1,2

COMFORT-II: Open-label, randomised, Phase III study versus BAT2,3

JAK2 Inhibitor for Myelofibrosis COMFORT-II study design - JAKAVI
  • "Real-world" comparator study— BAT included any single treatment or combination of treatments2,4
    • 34 (47%) patients received hydroxyurea
    • 49 (67%) patients received 1 or more BAT medications
    • 24 (33%) patients received no medication

Primary endpoint: Proportion of patients achieving a ≥35% reduction in spleen volume from baseline at Week 48 (as measured by MRI or CT scan)2

Secondary endpoints2:

  • Proportion of patients achieving a ≥35% reduction from baseline in spleen volume at Week 24
  • Duration of maintenance of a ≥35% reduction in spleen volume from baseline
  • Time to a reduction of ≥35% from baseline in spleen volume
  • Change in bone marrow histomorphology
  • Progression-free survival
  • Leukaemia-free survival
  • Overall survival
BAT=best available therapy; BID=twice daily; COMFORT=Controlled Myelofibrosis Study with Oral JAK Inhibitor; CT=computed tomography; MRI=magnetic resonance imaging.
