Myelodysplastic Syndrome (MDS) is a group of disorders that gradually affect the ability of a person's bone marrow (semi-liquid tissue present in many bones like backbones) to produce normal blood cells. Some people with MDS have a risk of the disease progressing to acute myeloid leukemia (AML), and a risk of death from the disease itself. Symptoms of MDS include fatigue, shortness of breath, unusual paleness due to anemia (low red blood cell count), easy or unusual bruising, and red spots just beneath the skin caused by bleeding. The purpose of this study is to see how safe and effective venetoclax and azacitidine (AZA) combination are when compared to AZA and a placebo (contains no medicine), in participants with newly diagnosed higher-risk MDS.
Venetoclax is an investigational drug being developed for the treatment of MDS. The study consists of two treatment arms - In one arm, participants will receive venetoclax and AZA. In another arm, participants will receive AZA and placebo. Adult participants with newly diagnosed higher-risk MDS will be enrolled. Around 500 participants will be enrolled in approximately 220 sites worldwide.
Participants in one arm will receive oral doses of venetoclax tablet and intravenous (infusion in the vein) or subcutaneous (given under the skin) AZA solution. Participants in another arm will receive oral doses of placebo tablet and intravenous or subcutaneous AZA solution.
There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the course of the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood and bone marrow tests, checking for side effects, and completing questionnaires.

Experimental: Arm 1: Venetoclax + Azacitidine (AZA)
Participants will receive venetoclax once daily (QD) (Days 1-14) in combination with AZA QD (7 days of the first 9 days) of each 28 day cycle.
Subcutaneous (SC) or Intravenous (IV) injection
Other Name: AZA
Active Comparator: Arm 2: Placebo + Azacitidine
Participants will receive placebo once daily (QD) (Days 1-14) in combination with AZA QD (7 days of the first 9 days) of each 28 day cycle.
Subcutaneous (SC) or Intravenous (IV) injection
Other Name: AZA
- Complete Remission (CR) [ Time Frame: Up To 36 Months ]CR is defined as achieving a complete remission at any time point during the study per the modified International Working Group (IWG) 2006 criteria for myelodysplastic syndrome (MDS).
- Overall survival (OS) [ Time Frame: Up To 5 Years ]OS is defined as the number of days from the date of randomization to the date of death of any cause, or last known date to be alive.
- Percentage of Participants Achieving Transfusion Independence (TI) Who are Transfusion Dependent at Baseline [ Time Frame: Up To 5 Years ]TI is when the participants who were transfusion dependent on RBC and/or Platelet at baseline achieve transfusion independence post baseline. TI is a period of at least 56 days with no transfusion after the date of the first dose of study drug to the last dose of study drug + 30 days, the initiation of post-treatment therapy, or death, whichever is earliest.
- Change in Patient-Reported Outcomes Measurement Information System (PROMIS)-Fatigue Short Form (SF) 7a Scale Score [ Time Frame: Up To 5 Years ]Fatigue will be assessed using the PROMIS Fatigue SF 7a Global Fatigue Score. PROMIS Fatigue SF 7a is a 7-item questionnaire that assesses the impact and experience of fatigue over the past 7 days. Participants rate items on a 5-point scale, with 1 as "never" an 5 as "always".
- Time to Deterioration in Physical Functioning as Measured by Physical Functioning Domain of the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) Scale [ Time Frame: Up To 5 Years ]Time to deterioration in physical functioning, as measured by the EORTC QLQ-C30 physical functioning score is defined as the time from the date of randomization to the date of death of any cause, or the first time worsening of score from baseline >= a pre-specified threshold. Participants rate items on a 4-point scale, with 1 as "not at all" and 4 as "very much."
- Overall Response (OR) [ Time Frame: Up To 5 Years ]OR [complete remission (CR) + partial response (PR)] is defined as achieving a CR or PR at any time point during the study per the modified IWG 2006 criteria for MDS.
- Modified Overall Response (mOR) [ Time Frame: Up To 5 Years ]mOR [complete remission (CR) + marrow complete remission (mCR) + partial response (PR)] is defined as achieving a CR, mCR, or PR at any time point during the study per the modified IWG 2006 criteria for MDS.
