What was measured
Percentage of participants without any RBC transfusion during any consecutive 24 weeks (168 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 and the day of randomization for participants enrolled in Phase 3. The 95% 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. Phase 3: ITT Analysis Set included all participants randomized into the Phase 3 study.
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.
Phase 3: 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.
Phase 3: Placebo
Imetelstat sodium-matching placebo administered IV, every 4 weeks (on a 28-day cycle), until death, lost to follow-up, withdrawal of consent, or study termination whichever occurs first.
