What was measured

RBC transfusion dependence is the percentage of participants who are transfusion dependent at Week 24, defined as having had at least 4 units of RBC transfusions, or a hemoglobin level below 8 g/dL in 8 weeks prior to Week 24 (excluding cases associated with clinically overt bleeding). Participants with the last double-blind phase participation date prior to Day 162 (ie. missing at Week 24) were considered transfusion dependent at Week 24.

Groups in this outcome

Momelotinib (MMB)

Participants received momelotinib plus placebo to match ruxolitinib. Momelotinib tablets were administered orally once daily at a starting dose of 200 mg. Additional available strengths included 100 mg and 150 mg. Placebo to match ruxolitinib tablets were administered orally twice daily.

Ruxolitinib (RUX)

Participants received ruxolitinib plus placebo to match momelotinib. Ruxolitinib tablets were administered orally twice daily. The dose ranged from 5 to 20 mg BID and was dependent on platelet count, creatinine clearance, and transaminase levels. Placebo to match momelotinib tablets were administered orally once daily.
