Study Endpoints

Primary Endpoints

Overall Response Rate (ORR) in Biomarker Positive AML or HR-MDS Participants Treated With Tamibarotene Monotherapy or in Combination With Azacitidine
Up to 48 months

ORR was defined as: AML: number of participants with complete remission (CR), CR with incomplete blood count recovery (CRi), CR with partial hematologic recovery (CRh), partial remission(PR), or morphologic leukemia-free state (MLFS) determined by the investigator per revised International Working Group (IWG) AML criteria. HR-MDS: the number of participants with CR, PR, marrow CR (mCR), or HI determined by the investigator per revised IWG MDS criteria.

Transfusion Independence Rate (TIR) for LR-MDS Participants Treated With Tamibarotene Monotherapy
Up to 48 months

TIR was defined as the number of participants who achieved transfusion independence defined as 8 consecutive weeks of red blood cell (RBC) transfusion independence.

Number of Participants With Treatment-emergent Adverse Events (TEAEs) Treated With Tamibarotene in Combination With Daratumumab
Up to 48 months

A TEAE was any untoward medical occurrence associated with use of a study drug/study participation, whether or not considered related to study drug after first dose. A TEAE was any unfavorable/unintended sign (including abnormal laboratory finding), symptom, or disease temporally associated with the study drug. A serious TEAE resulted in death, was life-threatening, required inpatient hospitalization/prolongation of existing hospitalization, persistent or significant disability/incapacity, congenital anomaly/birth defect in the offspring of a participant who received study drug or other important medical events. A summary of serious and all other non-serious adverse events regardless of causality is located in the Reported Adverse Events module.

R/R Non-APL AML or R/R HR-MDS: Tamibarotene MonotherapyEXPERIMENTALParticipants with R/R non-APL AML or R/R HR-MDS will receive tamibarotene at 6 mg/m\^2/day in 2 divided doses on Days 1-28 of a 28-day cycle.
Newly Diagnosed Non-APL AML: Tamibarotene MonotherapyEXPERIMENTALNewly diagnosed, treatment-naive participants with non-APL AML who were unlikely to tolerate standard intensive chemotherapy will receive tamibarotene at 6 mg/m\^2/day in 2 divided doses on Days 1-28 of a 28-day cycle.
Newly Diagnosed Non-APL AML: Tamibarotene and AzacitidineEXPERIMENTALNewly diagnosed, treatment-naive participants with non-APL AML who are unlikely to tolerate standard intensive chemotherapy will receive tamibarotene at 6 mg/m\^2/day in 2 divided doses on Days 8-28 of a 28-day cycle, and azacitidine at 75 mg/m\^2 once daily on Days 1-7 of a 28-day cycle.
LR-MDS: Tamibarotene MonotherapyEXPERIMENTALParticipants with transfusion-dependent LR-MDS without the del 5q abnormality who are refractory to erythropoietin (EPO) treatment or unlikely to respond to EPO treatment will receive tamibarotene at 6 mg/m\^2/day in 2 divided doses on Days 1-28 of a 28-day cycle.
R/R non-APL AML or R/R HR-MDS: Tamibarotene and DaratumumabEXPERIMENTALParticipants with R/R non-APL AML or R/R HR-MDS will receive tamibarotene at 6 mg/m\^2/day in 2 divided doses during a 7-day lead-in and on Days 1-28 of a 28-day cycle. Participants will also receive daratumumab at 16 mg/kg starting on Cycle 1 Day 1 once weekly for 8 weeks, followed by dosing every 2 weeks for 16 weeks, followed by dosing every 4 weeks.
R/R non-APL AML: Tamibarotene and AzacitidineEXPERIMENTALParticipants with R/R non-APL AML will receive tamibarotene at 6 mg/m\^2/day in 2 divided doses on Days 8-28 of a 28-day cycle, and azacitidine at 75 mg/m\^2 once daily on Days 1-7 of a 28-day cycle.
