Trial design

Randomised, placebo (0.9% sodium chloride injection) administered as iv infusion for three consecutive days in combination with cytarabine injection 2.0 g/m2/day iv infusion for five consecutive days (comparator arm).-controlled, adaptive Phase II/III trial across 32 sites in Belgium, Czechia, France and others.

Randomised
Yes
Comparator
Placebo (0.9% Sodium Chloride Injection) administered as IV infusion for three consecutive days in combination with Cytarabine Injection 2.0 g/m2/day IV infusion for five consecutive days (comparator arm).
Adaptive
True, Part A uses an adaptive design: initial randomization 1:1:1 to three arms (placebo, 190 mg/m2/day L-Annamycin, 230 mg/m2/day L-Annamycin), with interim analyses to identify optimal dose and potential dropping of an arm and re-randomization/enrollment adjustments; planned blind breaks after interim assessments as described in protocol.
Single Multiple Or Escalation Dose Combined
Yes
