Primary Outcome Measures :
  1. Overall Response Rate (ORR) [ Time Frame: Measured up to 2 years after the last participant has enrolled in the study. ]
    ORR is the proportion of participants with an overall response (complete remission [CR], plus complete remission with incomplete bone marrow recovery [CRi], plus nodular partial remission [nPR], plus partial remission [PR]) per the National Cancer Institute-Working Group (NCI-WG) guidelines as assessed by the Independent Review Committee (IRC).


Secondary Outcome Measures :
  1. Partial Remission (PR) rate [ Time Frame: Measured up to 2 years after the last participant has enrolled into the study. ]
    PR rate is defined as the proportion of subjects who achieved nPR or PR per the NCI-WG criteria (determined by the IRC).

  2. Event Free Survival (EFS) [ Time Frame: Measured up to 2 years after the last participant has enrolled into the study. ]
    EFS is defined as the number of days from the date of first dose to the date of earliest disease progression, death, or start of a new anti-leukemic therapy.

  3. Percent of participants who move on to stem cell transplant [ Time Frame: Measured up to 2 years after the last participant has enrolled into the study. ]
  4. Overall Survival (OS) [ Time Frame: Measured up to 5 years after the last participant has enrolled into the study. ]
    OS is defined as number of days from the date of first dose to the date of death.

  5. Progression Free Survival (PFS) [ Time Frame: Measured up to 5 years after the last participant has enrolled into the study. ]
    PFS is defined as the number of days from the date of first dose to the date of earliest disease progression (determined by the IRC) or death.

  6. Time to Progression (TTP) [ Time Frame: Measured up to 5 years after the last participant has enrolled into the study. ]
    TTP is defined as the number of days from the date of first dose to the date of earliest disease progression (determined by the IRC).

  7. Time to 50% reduction in absolute lymphocyte count (ALC) [ Time Frame: Measured up to 2 years after the last participant has enrolled into the study. ]
    Time to 50% reduction in ALC is defined as the number of days (hours if applicable) from the date of first dose to the date when the ALC has reduced to 50% of the baseline value

  8. Complete Remission (CR) rate [ Time Frame: Measured up to 2 years after the last participant has enrolled into the study. ]
    CR rate is defined as the proportion of participants who achieved a CR or CRi per the NCI-WG criteria (determined by the IRC).
