What was measured

Percentage of participants without any RBC transfusion during any consecutive 8 weeks (56 days) starting from Study Day 1 until subsequent anti-cancer therapy if any were reported. Study Day 1 is defined as the day of the first dose for participants enrolled in Phase 2. The 95% confidence interval (CI) was calculated using Clopper-Pearson method. Percentages were rounded off to the nearest single decimal place.

Analysis population: Phase 2: All Treated Analysis Set included all participants who received at least one dose of study drug.

Groups in this outcome

Phase 2: Imetelstat Sodium

Imetelstat sodium administered IV, at a starting dose of 7.5 mg/kg, every 4 weeks (on a 28-day cycle) until death, lost to follow-up, withdrawal of consent, or study termination whichever occurs first. Dose escalation to 9.4 mg/kg was allowed before Protocol Amendment 2.
