What was measured

As per the IWG Response Criteria 2006, CR was defined as Bone marrow: ≤5% myeloblasts with normal maturation of all cell lines; Peripheral blood (PB): Hb ≥11 g/dL; platelets ≥100 x 10\^9/dL; neutrophils ≥1.0 x 10\^9/liter; blasts: 0%. PR was defined as Bone marrow: ≤5% myeloblasts and decrease by ≥50% over pretreatment; cellularity and morphology not relevant. mCR was defined as Bone marrow: ≤5% myeloblasts and decreased by ≥50% over pre-treatment PB. Percentages were rounded off to the nearest single decimal place. All participants in Phase 2 were evaluated by the Investigator for CR/PR/mCR regardless of bone marrow blasts at baseline.

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.
