Brief Summary
The primary objectives of this study were: to assess the safety and tolerability, to determine the maximum tolerated dose (MTD) or maximum administered dose (MAD) and to determine the recommended Phase 2 dose (RP2D) of BGB-A1217 (known as ociperlimab) in combination with tislelizumab in participants with advanced solid tumors in phase 1.
