Study Overview
Brief Summary
This is a first-in-human (FIH) study that will evaluate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics, and preliminary antitumor activity of BGB-R046 as a single agent and in combination with tislelizumab (BGB-A317) in participants with advanced or metastatic immune-sensitive solid tumors.

Outcomes
Primary Outcomes
Phase 1a: Recommended Dose(s) for Expansion (RDFE[s]) of BGB-R046
Time Frame: 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)

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

Phase 1a: Maximum Tolerated Dose (MTD) or Maximum Administered Dose (MAD) of BGB-R046
Time Frame: 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
