Study Endpoints
Primary Endpoints
Phase 1a: Number of Participants with Adverse Events (AEs) and Serious Adverse Events (SAEs)
From first dose of the study drug(s) to 30 days after the last dose (up to approximately 2 years)

Number of participants with AEs and SAEs, including findings from abnormal laboratory assessments, and that meet protocol-defined dose-limiting toxicity (DLT) criteria or protocol-defined Adverse Event of Clinical Interest (AECI) criteria.

Phase 1a: Maximum Tolerated Dose (MTD) or Maximum Administered Dose (MAD)
Approximately 1 year

MTD is defined as the highest dose evaluated for which estimated toxicity rate is the closest to the target toxicity rate. MAD is defined as the highest dose administered if MTD is not reached.

Phase 1a: Recommended Dose(s) for Expansion (RDFE[s]) of BG-C477
Approximately 1 year

RDFE of BG-C477 monotherapy will be determined based upon available data.

Phase 1b: Overall Response Rate (ORR)
Approximately 2 years

ORR is defined as the percentage of participants with best overall response of complete response (CR) or partial response (PR), as assessed by the investigator per Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1.

Phase 1b: Recommended Phase 2 Dose (RP2D) of BG-C477
Approximately 2 years

RP2D of BG-C477 alone and in combination with anticancer agents will be determined based upon available data.

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

Phase 1a: BG-C477 Monotherapy Dose EscalationEXPERIMENTALSequential cohorts of increasing dose levels of BG-C477 will be evaluated as monotherapy.
Phase 1a: BG-C477 Monotherapy Safety ExpansionEXPERIMENTALSelected dose levels that have been determined to be safe in Phase 1a dose escalation will be further evaluated in monotherapy.
Phase 1b Part A: BG-C477 Monotherapy Expansion and Dose OptimizationEXPERIMENTALParticipants with selected advanced solid tumors will be evaluated at different dose levels of RDFEs identified in Phase 1a.
Phase 1b Part B: Combination Therapy ExpansionEXPERIMENTALSequential cohorts of increasing dose levels of BG-C477 will be evaluated in combination with anticancer agents, including chemotherapy or tislelizumab.
