Inclusion Criteria

Documented confirmation of acute myeloid leukemia (AML) according to the World Health Organization (WHO) criteria, previously untreated [OR]
- Documented diagnosis of previously untreated de novo myelodysplastic syndrome (MDS) according to the 2017 WHO classification with presence of < 20% bone marrow blasts per marrow biopsy/aspirate.
- Participants with documented MDS must meet the following disease activity criteria:
-- Overall revised international prognostic scoring system (IPSS-R) score > 3 (intermediate, high, or very high);
-- Eastern cooperative oncology group (ECOG) performance status of 0 to 2;
-- Hematopoietic stem cell transplant (HSCT) ineligible, or participant who chooses not to undergo HSCT.
- Participants with documented AML with adverse cytogenetic and/or molecular risk, and must be considered ineligible for induction therapy defined by the following:
-- >= 75 years of age; [OR]
-- >= 18 to 74 years of age with at least one of the following comorbidities:
--- Eastern cooperative oncology group (ECOG) performance status of 2 to 3;
--- Cardiac history of congestive heart failure requiring treatment or ejection fraction <= 50% or chronic stable angina;
--- Diffusion capacity of lung (DLCO) <= 65% or forced expiratory volume during the first second (FEV1) <= 65%;
--- Creatinine clearance >= 30 mL/min to < 45 mL/min;
--- Moderate hepatic impairment with total bilirubin > 1.5 to <= 3.0 x upper limit of normal (ULN);
--- Any other comorbidity that the physician judges to be incompatible with intensive chemotherapy or the participant declines to receive intensive chemotherapy.

Japan Safety Lead-In Phase:

- Documented diagnosis of MDS according to the 2017 WHO classification with presence of < 20% bone marrow blasts per marrow biopsy/aspirate, with intermediate- and high-risk relapsed/refractory MDS.
- Documented MDS must meet the following disease activity criteria:
-- ECOG performance status of 0 to 2.
