You may be eligible if
1. Must have:
1. Relapsed and/or refractory non-APL AML that has failed to achieve a complete remission (CR) or partial remission (PR) following standard induction therapy, or has relapsed after any duration of CR or PR i. Must have measurable disease with bone marrow blasts ≥5%at screening
2. Relapsed and/or refractory HR-MDS (High / Very High Risk, as defined by the Revised International Prognostic Scoring System (IPSS-R)) that has failed to achieve a CR or PR, or any hematologic improvement (HI, per IWG 2006 criteria) after standard therapy with hypomethylating agents (e.g., azacitidine, decitabine), or has relapsed after any duration of CR or PR or HI i. Must have measurable disease with bone marrow blasts \>5% at screening
3. Newly diagnosed, treatment-naïve non-APL AML in participants who, at the time of study entry are unlikely to tolerate standard intensive chemotherapy due to age, performance status, or comorbidities based on at least one of the following criteria:
* i. Age ≥ 75 years old
* ii. Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) of 3
* iii. Cardiac history of congestive heart failure (CHF) or documented ejection fraction (EF) ≤ 50%
* iv. Pulmonary disease with diffusing capacity of lung for carbon monoxide ≤ 65% or Forced Expiratory Volume in 1 Second ≤ 65%
* v. Creatinine clearance ≥ 30 milliliter (mL)/minute (min) to \< 45 mL/min
* vi. Hepatic impairment with total bilirubin \> 1.5 to ≤ 3.0 x upper limit of normal (ULN)
* vii. Any other comorbidity that the Investigator judges to be incompatible with intensive chemotherapy, and reviewed and approved by the Sponsor prior to enrollment
4. Transfusion-dependent LR-MDS without the del 5q abnormality, in participants refractory to erythropoietin treatment or unlikely to respond to erythropoietin treatment (EPO \>500).
* i. LR-MDS: Very Low /Low / Intermediate Risk, as defined by IPSS-R.
* ii.Red blood cell (RBC) transfusion-dependent anemia defined as no eight consecutive weeks without RBC transfusions within the 16 weeks prior to study entry, or ≥4 RBC transfusions within the 8 weeks prior to study entry.
* iii.Refractory to or ineligible for erythropoiesis-stimulating agents (ESAs) is defined as RBC-Transfusion Dependence despite ESA treatment of ≥40,000 units/week recombinant human erythropoietin for 8 weeks or an equivalent dose of darbepoetin (150 µg/week) or serum EPO level \>500 milliunits (mU)/mL in participants not previously treated with ESAs.
2. Participants must be evaluated for the RARA super-enhancer associated biomarker or RARA pathway associated biomarker at the time of study screening.
a. Participants treated with tamibarotene monotherapy and in combination with daratumumab, and R/R AML participants treated with tamibarotene in combination with azacitidine must be positive as defined by a pre-determined cut-off
3. Must be amenable to serial bone marrow aspirates and peripheral blood sampling during the study.
4. ECOG Performance Status (PS) of 0, 1 or 2. For newly diagnosed AML participants \< 75 years of age, ECOG 0-3; for ≥ 75 years of age, ECOG 0-2.
5. Adequate organ function as defined by:
1. Total bilirubin ≤ 1.5 x the upper limit of normal (ULN), unless suspected to have Gilbert's disease. For newly diagnosed AML participants \< 75 years of age, total bilirubin ≤ 3 x ULN; for ≥ 75 years of age, total bilirubin ≤ 1.5 x ULN.
2. Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ 3 x ULN or ≤ 5 x ULN if documented liver infiltration with leukemia cells
3. Serum creatinine ≤ 2.0 x ULN or calculated creatinine clearance ≥ 45 mL/min based on the Cockroft-Gault glomerular filtration rate estimation. For newly diagnosed AML participants \< 75 years of age, creatinine clearance ≥ 30 mL/min; for ≥ 75 years of age, creatinine clearance ≥ 45 mL/min.
6. Discontinued use of chemotherapy, radiation therapy, or growth factors for at least 2 weeks prior to first study treatment, with the exception of hydroxyurea.
7. No investigational agents within 2 weeks prior to first study treatment.
8. No strong inducers of CYP3A4 within 2 weeks prior to first study treatment.
9. Resolved acute effects of any prior AML/MDS therapy to baseline or ≤ Grade 1 CTCAE severity.
You may not be if
1. Acute promyelocytic leukemia (APL, M3 subtype of AML) or participants with a t(9:22) cytogenetic translocation.
2. Hyperleukocytosis (leukocytes ≥25 x 109/L) at study entry. The participants may be treated with hydroxyurea according to routine practice, and enroll in the study when the leukocyte count falls below 25 x 109/L.
3. Participants known to be refractory to platelet or packed red cell transfusions per Institutional Guidelines, or a participant who refuses blood product support.
4. Prior treatment with all-trans retinoic acid (ATRA) or systemic retinoid for the treatment of hematologic malignancy.
5. Tamibarotene and daratumumab combination only - Prior or concurrent exposure to daratumumab or other CD38 therapies.
6. Tamibarotene and daratumumab combination only - Participant has either of the following:
1. Known chronic obstructive pulmonary disease (COPD) with a forced expiratory volume in 1 second (FEV1) \<50% of predicted normal. Note that FEV1 testing is required for participants suspected of having COPD and participants must be excluded if FEV1 is \<50% of predicted normal.
2. Known moderate or severe persistent asthma within the past 2 years, or uncontrolled asthma of any classification. Note that participants who currently have controlled intermittent asthma or controlled mild persistent asthma are allowed to participate in the study.
7. Participants with active malignancy (not including basal cell carcinoma, non-melanoma skin cancer, cervical carcinoma in situ, localized prostate cancer treated with hormone therapy). Participants with history of other cancers should be free of disease for at least 2 years.
8. Participants with hypertriglyceridemia defined as \>1000 mg/dL (CTCAE Grade 4).
9. Participants with clinically significant cardiac disease including one of the following currently or in the previous 6 months: myocardial infarction, unstable cardiac function due to unstable angina or congestive heart failure, congenital long QT syndrome, torsades de pointes or significant ventricular arrhythmias.
10. Participants with known active uncontrolled central nervous system (CNS) leukemia.
11. Participants taking Vitamin A supplements (\>10,000 IU/d) unless discontinued prior to first dose of study drug, or having hypervitaminosis.
