Group Intervention Description Phase 1a: Part A: Dose Escalation Monotherapy BGB-R046 Sequential cohorts of increasing dose levels of BGB R046 will be evaluated as monotherapy. Phase 1a: Part B: Dose Escalation Combination Therapy BGB-R046 Sequential cohorts of increasing dose levels of BGB R046 will be evaluated in combination with tislelizumab. Phase 1a: Part B: Dose Escalation Combination Therapy Tislelizumab Sequential cohorts of increasing dose levels of BGB R046 will be evaluated in combination with tislelizumab. Phase 1b: Dose Expansion Tislelizumab The recommended dose for expansion (RDFE) for BGB-R046 in combination with tislelizumab from Phase 1a will be evaluated in selected indications. Phase 1b: Dose Expansion BGB-R046 The recommended dose for expansion (RDFE) for BGB-R046 in combination with tislelizumab from Phase 1a will be evaluated in selected indications.
- Primary Outcome Measures
Name Time Method Phase 1a: Number of Participants with Adverse Events (AEs) and Serious Adverse Events (SAEs) Up to approximately 2 years Number of participants with AEs including serious adverse events (SAEs), defined as any unfavorable and unintended sign (including abnormal laboratory findings), symptom, or disease temporally associated with the use of study drugs, whether considered related to study drugs or not as graded by the National Cancer Institute-Common Terminology Criteria for Adverse Events \[NCI CTCAE) V5.0/American Society for Transplantation and Cellular Therapy (ASTCT) for cytokine release syndrome \[CRS\] and immune effector cell associated neurotoxicity syndrome \[ICANS\])
Phase 1a: Maximum Tolerated Dose (MTD) of BGB-R046 Up to approximately 2 years MTD is defined as the highest dose evaluated for which the estimated toxicity rate is closest to the target toxicity rate of 30% or the highest dose administered, respectively
Phase 1a: Maximum Administered Dose (MAD) of BGB-R046 Up to approximately 2 years MAD is defined as the highest dose evaluated for which the estimated toxicity rate is closest to the target toxicity rate of 30% or the highest dose administered, respectively
Phase 1a: Recommended Dose(s) for Expansion (RDFE[s]) of BGB-R046 Up to approximately 2 years The potential RDFE\[s\] of BGB-R046 administered as monotherapy and in combination with tislelizumab will be determined based on the totality of the data and will also take in consideration the long term tolerability, pharmacokinetics, preliminary antitumor activity and any other relevant data 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) as determined by investigators per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1
