Study Endpoints

Primary Endpoints

Part 1a: Number of Participants with Adverse Events (AEs) and Serious Adverse Events (SAEs)
From first dose to 30 days after last dose or initiation of a new anticancer therapy, whichever occurs first, up to approximately18 months

An AE is defined as any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporarily associated with the use of study treatment, whether considered related to study treatment or not. An SAE is any untoward medical occurrence that, at any dose, * Results in death * Is life-threatening * Requires hospitalization or prolongation of existing hospitalization * Results in disability/incapacity * Is congenital anomaly/birth defect * Is considered a significant medical AE by the investigator based on medical judgement

Phase 1a: Recommended Dose for Expansion (RDFE) of BG-75202
Estimated approximately 18 months

The potential RDFE(s) of BG-75202 as monotherapy or in combination with HMA are based upon the maximum tolerated dose (MTD) or maximum administered dose (MAD), with consideration of the tolerability, pharmacokinetics (PK), pharmacodynamics, antitumor activity, and any other available relevant data.

Phase 1b: Dose Optimization: Complete Remission (CR) Rate
Up to approximately 12 months

CR rate is defined as the percentage of participants who achieved a best response of CR as assessed by investigator's review.

Phase 1b: Dose Optimization: Complete Remission (CR) plus CR With Partial Hematologic Recovery (CRh) Rate
Up to approximately 12 months

CR + CRh rate is defined as the percentage of participants who achieved the best response of CR or CRh as assessed by investigator's review.

Part 1: Number of Participants with Adverse Events (AEs)
From first dose to 30 days after last dose or initiation of a new anticancer therapy, whichever occurs first, up to approximately 12 months

Number of participants with treatment-emergent adverse events (TEAEs) and serious adverse events (SAEs), including physical examination findings, electrocardiogram results, laboratory values, and AEs meeting protocol-defined dose-limiting toxicity (DLT) criteria.

Part 1: Recommended Dose for Expansion (RDFE)
Estimated approximately 1 year

The RDFE is based on the maximum tolerated dose (MTD) or maximum administered dose (MAD) with consideration of the tolerability, pharmacokinetics (PK), pharmacodynamics, antitumor activity, and any other available relevant data.

Part 2: Overall Response Rate (ORR)
Up to approximately 2 years

ORR is defined as the percentage of participants with partial or complete response, as assessed by the investigator using Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1).

Secondary Endpoints

Phase 1b Dose Optimization: Number of Participants with Adverse Events (AEs)
From first dose to 30 days after last dose or initiation of a new anticancer therapy, whichever occurs first, up to approximately 18 months
Phase 1b: Time to Response (TTR)
Up to approximately 12 months
