Study Endpoints
Primary Endpoints
Phase 1a: Number of Participants with Adverse Events (AEs) and Serious Adverse Events (SAEs)
Approximately 3 years

Number of participants with AEs and SAEs (as graded by the National Cancer Institute-Common Terminology Criteria for Adverse Events \[NCI-CTCAE\] Version \[v\] 5.0),, including findings from physical examinations, electrocardiograms (ECGs), laboratory assessments, and that meet protocol-defined dose-limiting toxicity criteria.

Phase 1a: Maximum Tolerated Dose (MTD) or Maximum Administered Dose (MAD) of BG-C9074
Approximately 18 months

Defined as the highest dose evaluated 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 for Expansion (RDFE) of BG-C9074.
Approximately 18 months

The potential RDFE(s) of BG-C9074 alone and in combination with tislelizumab will be determined based on the MTD or MAD, taking into consideration the long-term tolerability, PK, pharmacodynamics, preliminary antitumor activity, and any other relevant data, as available

Phase 1b: Overall Response Rate (ORR) as monotherapy and in combination with tislelizumab
Approximately 3 years

ORR is defined as the percentage of participants with best overall response (BOR) of complete response (CR) or partial response (PR) assessed by the investigator using RECIST v1.1.

Phase 1b: Recommended Phase 2 dose (RP2D) of BG-C9074 as monotherapy and in combination with bevacizumab or tislelizumab
Approximately 30 months

The RP2D of BG-C9074 will be determined based on safety, PK, pharmacodynamics, preliminary antitumor activity, and other relevant data, as available.

Secondary Endpoints
Phase 1a: ORR as monotherapy and in combination with tislelizumab
Approximately 3 years
Phase 1b: ORR as monotherapy and in combination with bevacizumab or tislelizumab
Approximately 3 years
Phase 1b: ORR per B7-H4 (B7 homolog 4) protein expression
Approximately 3 years

Phase 1a: Part A (Monotherapy Dose Escalation)EXPERIMENTALBG-C9074 monotherapy dose escalation
Phase 1a: Part B (Monotherapy Safety Expansion)EXPERIMENTALBG-C9074 dose levels that have been determined to be safe and tolerable in Part A will be investigated.
Phase 1a: Part C (Combination Therapy Dose Escalation)EXPERIMENTALBG-C9074 plus tislelizumab combination at the recommended dose for expansion (RDFE).
Phase 1a: Part D (Japan Cohort)EXPERIMENTALA separate cohort in Japan will evaluate the safety of BG-C9074 monotherapy in Japanese participants with select solid tumors
Phase 1b: Monotherapy Dose ExpansionEXPERIMENTALThe monotherapy dose expansion phase will begin once the BG-C9074 monotherapy RDFE and dosing schedule have been determined from Parts A and B in Phase 1a.
Phase 1b: Combination Therapy Dose Expansion (BG-C9074 plus tislelizumab)EXPERIMENTALThis arm will assess BG-C9074 plus tislelizumab as first-line therapy in select solid tumors after completion of the dose escalation phase.
Phase 1b: Combination Therapy Dose Expansion (BG-C9074 plus bevacizumab)EXPERIMENTALThis arm will assess BG-C9074 plus bevacizumab in select solid tumors participants after establishing the recommended monotherapy dose and schedule.
