- Overall Response Rate (ORR) [ Time Frame: Baseline up to approximately 8 months ]Defined as the percentage of participants with an objective response (complete response [CR] or partial response [PR]) according to Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1) as determined by independent central radiographic review (ICR).
- Duration of Response (DOR) [ Time Frame: Up to approximately 2 years ]Defined as the time from an initial objective response (CR or PR) according to RECIST v1.1 until disease progression as determined by ICR or death due to any cause.
- Disease Control Rate (DCR) [ Time Frame: Up to approximately 2 years ]Defined as the proportion of participants with either an objective response or stable disease lasting at least 6 months.
- Progression Free Survival (PFS) [ Time Frame: Up to approximately 2 years ]Defined as the time from the start of therapy until disease progression as determined by the ICR or death due to any cause.
- Overall survival (OS) [ Time Frame: Up to approximately 2 years ]Defined as the time from the start of therapy until death due to any cause.
- Number of Treatment-Emergent Adverse Events (TEAE) [ Time Frame: Up to approximately 2 years ]Adverse events reported for the first time or worsening of a pre-existing event after first dose of study treatment.
- Cmax of INCMGA00012 [ Time Frame: Up to approximately 6 months ]Maximum observed serum concentration.
- tmax of INCMGA00012 [ Time Frame: Up to approximately 6 months ]Time to maximum concentration.
- Cmin of INCMGA00012 [ Time Frame: Up to approximately 6 months ]Minimum observed serum concentration over the dose interval.
- AUCt of INCMGA00012 [ Time Frame: Up to approximately 6 months ]Area under the serum concentration-time curve.
