Study Endpoints
Primary Endpoints
Phase 1a: Number of Participants with Adverse Events (AEs) and Serious Adverse Events (SAEs)
Up to approximately 2 years

Number of participants with AEs and SAEs as graded by the National Cancer Institute- Common Terminology Criteria for Adverse Events Version (NCI CTCAE 5.0)), including AEs that meet protocol-defined dose-limiting toxicity (DLT) criteria and AEs meeting protocol-defined adverse event of clinical interest (AECIs)

Phase 1a: Maximum Tolerated Dose (MTD) or Maximum Administered Dose (MAD) of BG-C137
Up to approximately 2 years

The MTD or MAD is defined as the highest dose evaluated for which the estimated toxicity rate is closest to a target toxicity rate, or the highest dose administered, respectively.

Phase 1a: Recommended Dose(s) for Expansion (RDFE[s]) of BG-C137 as monotherapy and in combination with anticancer agents
Up to approximately 2 years

RDFE(s) is determined based on relevant data, as available

Phase 1b: The recommended Phase 2 dose (RP2D) of BG-C137
Up to approximately 2 years

The RP2D of BG-C137 monotherapy will be determined based on relevant data, as available

Phase 1b: Overall Response Rate (ORR)
Up to approximately 2 years

ORR is defined as the percentage of participants with confirmed complete response (CR) or partial response (PR) by Response Evaluations Criteria in Solid Tumors Version 1.1 (RECIST v1.1)

Secondary Endpoints
Phase 1a: ORR
Up to approximately 2 years
Phase 1a and 1b: Disease Control Rate (DCR)
Up to approximately 2 years
Phase 1a and 1b: Duration of Response (DOR)
Up to approximately 2 years
