Kaplan-Meier curve for overall survival, ITT population1
The Phase 3 study was a randomized, multicenter, open-label, active-controlled superiority study of VYXEOS versus cytarabine and daunorubicin (7+3) in patients 60 to 75 years of age with newly-diagnosed t-AML or AML-MRC. There were 153 patients randomized to VYXEOS and 156 patients randomized to the 7+3 arm. Twenty percent had t-AML, 54% had AML with an antecedent hematological disorder, and 25% had de novo AML with MDS-related cytogenetic abnormalities. Efficacy was established on the basis of overall survival from the date of randomization to death from any cause.
VYXEOS 44 mg/100 mg per m2 (daunorubicin/cytarabine) was given intravenously on Days 1, 3, and 5 for first induction and on Days 1 and 3 for those needing a second induction. For consolidation, the VYXEOS dose was 29 mg/65 mg per m2 (daunorubicin/cytarabine) on Days 1 and 3. In the 7+3 arm, first induction was cytarabine 100 mg/m2/day on Days 1-7 by continuous infusion + daunorubicin 60 mg/m2/day on Days 1-3. For second induction and consolidation, cytarabine was dosed on Days 1-5 and daunorubicin on Days 1 and 2. Patients could receive up to 2 cycles of induction and 2 cycles of consolidation in each arm. Subsequent induction was recommended for patients who did not achieve a response and was mandatory for patients achieving >50% reduction in percent blasts.
