Study Endpoints
Primary Endpoints
Phase 1a: Number of Participants Experiencing Adverse Events (AEs)
Up to approximately 24 months

Number of participants with treatment-emergent adverse events (TEAEs) and serious adverse events (SAEs), including dose limiting toxicities (DLTs), AEs meeting protocol-defined adverse event of clinical interest (AECI) criteria, laboratory values, and electrocardiogram results.

Phase 1a: Maximum Tolerated Dose (MTD) or Maximum Administered Dose (MAD) of BG-C0979 Monotherapy
Up to approximately 10 months

MTD or MAD, defined as the highest dose for which the estimated toxicity rate is closest to the target toxicity rate of 28%, or the highest dose administered, respectively.

Phase 1a: Recommended Dose(s) for Expansion (RDFE[s])
Up to approximately 10 months

The potential RDFE(s) of BG-C0979 will be determined based on the totality of data including the MTD or MAD, long-term tolerability, pharmacokinetics (PK), preliminary antitumor activity, and any other relevant data, as available.

Phase 1b: Recommended Phase 2 Dose (RP2D)
Up to approximately 24 months

RP2D of BG-C0979 alone and in combination with tislelizumab will be determined based on safety, PK, preliminary antitumor activity, and other relevant data, as available.

Phase 1b: Overall Response Rate (ORR)
Up to approximately 24 months

ORR as determined from tumor assessment by the investigator using Response Evaluation Criteria in Solid Tumors (RECIST) v1.1. For castration-resistant prostate cancer (CRPC), ORR will be assessed by RECIST v1.1 criteria for soft tissue and Prostate Cancer Clinical Trials Working Group 3 (PCWG3) criteria for bone lesions. ORR is defined as the percentage of participants with best overall response of a complete response (CR) or partial response (PR).

Secondary Endpoints
Phase 1a: ORR
Up to approximately 24 months
Phase 1a and 1b: Duration of Response (DOR)
Up to approximately 24 months
Phase 1a and 1b: Disease Control Rate (DCR)
Up to approximately 24 months

Phase 1a: Monotherapy Dose EscalationEXPERIMENTALParticipants will receive increasing doses of BG-C0979 as monotherapy.
Phase 1a: Monotherapy Safety ExpansionEXPERIMENTALParticipants will receive BG-C0979 as monotherapy. Selected dose levels that have been determined to be safe in Phase 1a dose escalation will be further evaluated in safety expansion.
Phase 1b, Part A: Monotherapy Dose Optimization and Dose ExpansionEXPERIMENTALParticipants will receive BG-C0979 as monotherapy in a dose optimization and dose expansion phase at different dose levels of recommended doses for expansion (RDFEs) identified in Phase 1a.
Phase 1b, Part B: Combination Therapy ExpansionEXPERIMENTALParticipants will receive BG-C0979 in combination with tislelizumab in select tumor types.
