Primary Outcome Measures:
  • Overall survival [ Time Frame: Up to 5 years or duration of study ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • CR rate [ Time Frame: Up to 5 years or duration of study ] [ Designated as safety issue: No ]

Arms Assigned Interventions
Experimental: Group A: vosaroxin + cytarabine
Vosaroxin will be administered in a blinded manner as a short IV infusion within 10 minutes on days 1 and 4 of each cycle (up to 4 cycles) and cytarabine will be administered in an unblinded manner as a 2-hour infusion on days 1-5 of each cycle.
Drug: vosaroxin and cytarabine

Vosaroxin days 1 and 4: 90 mg/m2 for induction 1; 70 mg/m2 for all other cycles

Cytarabine 1 g/m2 daily on days 1-5 (IDAC)

Experimental: Group B: placebo + cytarabine
Placebo will be administered in a blinded manner as a short IV infusion within 10 minutes on days 1 and 4 of each cycle (up to 4 cycles) and cytarabine will be administered in an unblinded manner as a 2-hour infusion on days 1-5 of each cycle.
Drug: placebo and cytarabine

Placebo days 1 and 4: volume matched to vosaroxin

Cytarabine 1 g/m2 daily on days 1-5 (IDAC)


Detailed Description:

Other objectives of this study include comparing the following between treatment groups:

Complete remission (CR) rate

Safety and tolerability

Combined CR rate, defined as CR+CRp+CRi

Overall remission (OR) rate

Event-free survival (EFS)

Durability of remission (CR and combined CR) assessed by leukemia-free survival (LFS)

Percentage of patients who have post-treatment transplantation
