  • Objective

    1 - Minimal residual disease (MRD) negative second remission (Rem-2) rate (Group 1) [ Time Frame: Up to 2 cycles of therapy (each cycle = 36 days) ]
    Will be defined as Rem-2 and bone marrow with MRD < 0.01% by flow cytometry. Will be compared using a one-sided Z test of proportions with type I error of 0.10.

    2 - Event-free survival post-induction (Group 3) [ Time Frame: From date of randomization to date of relapse, disease progression, second malignancy (SMN) or death due to any cause, assessed up to 3 years ]
    The primary analysis between Arm E versus Arm F will be based on a one-sided two-sample logrank test with type I error of 0.10, to be conducted 3 years after completion of enrollment of Group 3.
