Study Endpoints

Primary Endpoints

Objective response rate
From baseline to the end of study, up to approximately 2 years

Objective response rate, which is defined as the proportion of participants who have a confirmed complete response (CR) or a partial response (PR), as the best overall response determined by the Investigator as per the Response Evaluation Criteria in Solid Tumors (RECIST) v1.1

Dose escalation part 1A, 1C and Japan Cohort F: Presence of dose-limiting toxicities (DLTs) in Cycles 1 and 2
Cycles 1 & 2 - 14 days per cycle

DLTs will be defined using NCI CTCAE version 5.0 or ASTCT criteria for CRS or immune effector cell-associated neurotoxicity syndrome (ICANS)

Dose escalation part 1B: Presence of dose-limiting toxicities (DLTs) in Cycle 1 to 3 in part B
Cycle 1 to 3 -14 days per cycle
Dose escalation and Japan Cohort F: Percentage of participants experiencing treatment-emergent adverse events (TEAEs)
The time from the first dose of study interventions up to 30 days after last dose of study interventions

Presence of TEAEs, SAEs, and lab abnormalities, according to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) Version 5.0 and American Society for Transplantation and Cellular Therapy (ASTCT) consensus grading

Dose expansion/optimization: Objective response rate (ORR)
From baseline to the end of dose expansion/optimization (up to 2 years)

Proportion of participants who have a confirmed complete response (CR) or a partial response (PR), as the best overall response (BOR) determined by the Investigator as per the Response Evaluation Criteria in Solid Tumors (RECIST) v1.1

Secondary Endpoints
