- Number of Participants With Adverse Events (AEs) [ Time Frame: Up to Maximum of 24 months ]An adverse event (AE) is defined as any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product which does not necessarily have a causal relationship with this treatment. The investigator assesses the relationship of each event to the use of study. A serious adverse event (SAE) is an event that results in death, is life-threatening, requires or prolongs hospitalization, results in a congenital anomaly, persistent or significant disability/incapacity or is an important medical event that, based on medical judgment, may jeopardize the participant and may require medical or surgical intervention to prevent any of the outcomes listed above. Treatment-emergent adverse events/treatment-emergent serious adverse events (TEAEs/TESAEs) are defined as any event that began or worsened in severity on or after the first dose of study drug.
Secondary Outcome Measures :
- Event-Free Survival (EFS) [ Time Frame: Measured from the date of the first dose of study drug to date of earliest disease progression, death, or initiation of new non-protocol-specified anti-MDS therapy without documented progression, and for up to 5 years after the last subject is enrolled. ]
- Overall Survival (OS) [ Time Frame: Measured from the date of first dose of study drug to the date of death, and for up to 5 years after the last subject is enrolled. ]
- Rate of Modified Overall Response (mORR) [ Time Frame: Measured from Cycle 1 Day 1 (C1D1) as long as the subject continues to benefit, or until the occurrence of unacceptable toxicity, death, exercise of investigator discretion, or withdrawal of consent, and for an anticipated maximum duration of 24 months. ]Proportion of participants with a mORR using best outcome will be calculated.
- Time to next treatment (TTNT) [ Time Frame: Measured from first dose of study drug to start of new non-protocol specified MDS therapy, and for up to 5 years after the last subject is enrolled. ]
- Duration of mORR [ Time Frame: Measured from the date of first response (CR, mCR or PR) to the earliest documentation of progressive disease (PD), and for an anticipated maximum duration of 24 months. ]Defined as the number of days from the date of first response (CR, mCR or PR) to the earliest documentation of progressive disease or death of any cause, whichever occurs earlier..

- Time to Transformation acute myeloid leukemia (AML) [ Time Frame: Measured from the date of first dose of study drug to the date of documented AML transformation for an anticipated maximum duration of 24 months. ]Defined as blast count greater than or equal to 20% in either peripheral blood or bone marrow.
- Progression-Free Survival (PFS) [ Time Frame: Measured from the date of the first dose of study drug to the date of earliest disease progression or death, and for an anticipated maximum duration of 24 months. ]
- Overall Response Rate (ORR) [ Time Frame: Measured from Cycle 1 Day 1 as long as the subject continues to benefit, or until the occurrence of unacceptable toxicity, death, exercise of investigator discretion, or withdrawal of consent, and for an anticipated maximum duration of 24 months. ]ORR (equals the sum of rates of complete remission [CR] + marrow complete remission (mCR) + partial remission [PR]) of venetoclax as a single-agent and in combination with azacitidine.
- Complete Remission (CR) Rate [ Time Frame: Measured from Cycle 1 Day 1 as long as the subject continues to benefit, or until the occurrence of unacceptable toxicity, death, exercise of investigator discretion, or withdrawal of consent, and for an anticipated maximum duration of 24 months. ]Proportion of subjects who achieved a complete remission.
- Rate of red blood cell (RBC) transfusion independence [ Time Frame: Measured from Cycle 1 Day 1 as long as the subject continues to benefit, or until the occurrence of unacceptable toxicity, death, exercise of investigator discretion, or withdrawal of consent, and for an anticipated maximum duration of 24 months. ]Proportion of red blood cell (RBC) transfusion independence.
- Duration of Complete Response (CR) [ Time Frame: Measured from date of first response (CR) to the to the earliest documentation of progressive disease or death of any cause, and for an anticipated maximum duration of 24 months. ]Duration of CR will be defined as the number of days from the date of first response CR to the earliest documentation of progressive disease or death of any cause, whichever occurs earlier.
- Rate of Hematologic Improvement (HI) [ Time Frame: Measured from Cycle 1 Day 1 as long as the subject continues to benefit, or until the occurrence of unacceptable toxicity, death, exercise of investigator discretion, or withdrawal of consent, and for an anticipated maximum duration of 24 months. ]Proportion of participants with HI (erythroid/platelet/neutrophil responses)
- Rate of marrow complete remission (mCR) [ Time Frame: Measured from Cycle 1 Day 1 (C1D1) as long as the subject continues to benefit, or until the occurrence of unacceptable toxicity, death, exercise of investigator discretion, or withdrawal of consent, and for an anticipated maximum duration of 24 months. ]Proportion of participants with marrow complete remission with or without hematological improvement.
- Duration of ORR [ Time Frame: Measured from the date of first response (CR or PR) to the earliest documentation of progressive disease or death of any cause, and for an anticipated maximum duration of 24 months. ]Duration of response (ORR) will be defined as the number of days from the date of first response (CR or PR) to the earliest documentation of progressive disease or death of any cause, whichever occurs earlier.
