Primary Outcome Measures
NameTimeMethod
Adverse events (AEs)approximately 3 years

Incidence of treatment-related AEs

Secondary Outcome Measures
NameTimeMethod
Objective Response Rate (ORR)approximately 3 years

Overall response rate (ORR) was defined as the percentage of participants with a best overall complete response (CR) or partial response (PR) per RECIST 1.1.

Progression-free survival (PFS)approximately 3 years

Progression-free survival (PFS) was defined as the time from the start date of study drug to the date of the first radiologically documented progressive disease (PD) per RECIST 1.1 or death due to any cause.

Disease Control Rate (DCR)approximately 3 years

Disease Control Rate (DCR) was defined as the percentage of participants with a best overall complete response (CR), partial response (PR), or stable disease (SD) per RECIST 1.1.

Duration of Response (DOR)approximately 3 years

Duration of response (DOR) was defined as the time from first documented response (partial response (PR) or complete response (CR)) to the date of first documented disease progression (PD) or death due to any cause, among patients with a confirmed PR or CR per RECIST 1.1.
