  • Spleen volumeFrom baseline at 24 weeks

    To compare the efficacy of pacritinib with that of physician's choice (P/C) therapy, as assessed by the proportion of patients achieving a ≥35% spleen volume reduction (SVR) as measured by magnetic resonance imaging (MRI, preferred) or computed tomography (CT) scans

  • Total Symptom Score (TSS) (excluding tiredness)From baseline at Week 24

    To compare the efficacy of pacritinib compared to P/C therapy, as assessed by the proportion of patients achieving a ≥50% reduction in Total Symptom Score (TSS). The TSS is the sum of the individual symptom scores for tiredness, early satiety, abdominal discomfort, night sweats, pruritus, bone pain, and pain under ribs on the left side. Symptoms are ranked 0 (absent) to 10 (worst imaginable)
