Study Endpoints

Primary Endpoints

Objective Response Rate (ORR)
1 year

Investigator-Assessed ORR per Response Evaluation Criteria In Solid Tumors (RECIST v1.1) for target lesions as assessed by CT or magnetic resonance imaging (MRI) scans (with IV contrast unless contraindicated) of the chest, abdomen, and pelvis every 2 cycles (each cycle is a 28 day cycle). Reported as the number of patients with a complete response (CR) or partial response (PR); ORR = CR+PR; CR = Disappearance of all target lesions.Any pathological lymph nodes (whether target ornon-target) must have reduction in short axis to\<10 mm. PR= At least a 30% decrease in the sum ofdiameters of target lesions, taking as reference the baseline sum diameters.

Number of participants with adverse events (AEs)
Up to 2 years
Number of participants with serious adverse events (SAEs)
Up to 2 years
Number of participants with AEs leading to study treatment discontinuation
Up to 2 years

Secondary Endpoints
