Tamibarotene is being studied as a treatment for participants with a type of leukemia called acute myeloid leukemia, or AML for short. Tamibarotene is being studied as a treatment for participants with AML whose cancer has a specific genetic abnormality characterized by the overexpression of the retinoic acid receptor alpha (RARA) gene. This genetic profile is found in about 3 of every 10 people with AML.
During the trial, tamibarotene will be given with 2 other drugs that are already used together to treat people who have AML and who cannot start treatment with standard chemotherapy.

Experimental: Part 1: Tamibarotene/Venetoclax/Azacitidine
Participants will receive the tamibarotene/venetoclax/azacitidine triplet combination as follows: Azacitidine (intravenously or subcutaneously) at 75 milligrams (mg)/square meter (m^2) once daily, on Days 1 through 7 of each 28-day therapy cycle (per VIDAZA USPI). Alternative dosing of azacitidine (Days 1 through 5, 8, and 9) will be permitted throughout the study. Venetoclax (orally) daily on Days 1 through 28 per standard of care. Standard of care daily dosing is 100 mg on Day 1, 200 mg on Day 2, and 400 mg on Day 3 and beyond. Tamibarotene 6 mg twice daily (BID) orally, on Days 8 through 28 of each 28-day therapy cycle. Tamibarotene will only be administered to participants who have been confirmed as RARA-positive. |

- Part 1: Number of Participants With Adverse Events [ Time Frame: up to 3 years ]
- Part 2: CR/CRi Rate [ Time Frame: up to 3 years ]CR/CRi rate is estimated by the proportion of participants who achieve CR/CRi (as determined by the investigator).
- Part 1: Overall Response Rate (ORR) [ Time Frame: up to 3 years ]Overall response assessment is comprised of CR, CRi, CR with partial hematologic recovery (CRh), morphologically leukemia-free state (MLFS), or partial remission (PR) (as determined by the investigator). ORR is estimated by the proportion of participants who achieve overall response.

Note: all inclusion/exclusion criteria should be met prior to the first dose of venetoclax/azacitidine on Cycle 1 Day 1 with the exception of the RARA-biomarker test result referenced in inclusion criterion 2, which should be positive by Cycle 1 Day 8 to continue treatment on study.
Inclusion Criteria:
- All participants must have obtained a blood sample for RARA biomarker investigational assay testing prior to starting treatment on Cycle 1 Day 1. The results of the investigational biomarker assay for all participants must be confirmed as RARA-positive by Cycle 1 Day 8 to enroll (Part 1) or to be randomized (Part 2) in the study.
-
Participants must have newly diagnosed, previously untreated non-acute promyelocytic leukemia (APL) AML with a bone marrow or peripheral blood blast count ≥20% and must be unlikely to tolerate standard intensive chemotherapy at the time of Cycle 1 Day 1 Visit due to age, performance status, or comorbidities based on at least one of the following criteria:
- age ≥75 years old, or
-
age <75 years old, with at least one of the following:
- Eastern Cooperative Oncology Group (ECOG) performance status of 3
- cardiac history of congestive heart failure (CHF) or documented ejection fraction (EF) ≤50%
- pulmonary disease with diffusing capacity of the lungs for carbon monoxide (DLCO) ≤65% or forced expiratory volume in one second (FEV1) ≤65%
- creatinine clearance ≥30 milliliters (mL)/minute (min) to <45 mL/min based on the Cockcroft-Gault glomerular filtration rate estimation
- hepatic impairment with total bilirubin >1.5 to ≤3.0 * upper limit of normal (ULN)
- any other comorbidity that the investigator judges to be incompatible with intensive chemotherapy, and reviewed and approved by the sponsor.
Exclusion Criteria:
- Participants have APL.
- Participants have known active central nervous system involvement with AML.
- Prior treatment (before Cycle 1 Day 1) for the diagnosis of AML, myelodysplastic syndromes (MDS), or antecedent hematologic malignancy with any hypomethylating agent, venetoclax, chemotherapy, or hematopoietic stem cell transplantation (HSCT), with the exception of prior treatment with hydroxyurea.
