What was measured

PFS was defined as the length of time between the date of the first dose and the earlier of death or progressive disease as assessed by RECIST v1.1. Pleural mesothelioma was evaluated using modified RECIST criteria. Participants enrolled in Part 1c had renal impairment. These participants received INCB001158 50 mg + pembrolizumab, which was half the recommended Phase 2 dose of INCB001158. In renally impaired participants, the 50 mg dose has comparable exposure to 100 mg in participants with normal renal function. It was pre-specified to combine Part 1c and Part 3 participants for efficacy analysis based on planned comparable dosing according to renal function.

Analysis population: PFS Efficacy Evaluable Population (Full Analysis Set): all participants who received at least 1 dose of INCB001158 or pembrolizumab. One participant was to be treated with INCB001158 100 mg + pembrolizumab but actually received INCB001158 75 mg + pembrolizumab. For PFS analysis, this participant was analyzed in their planned treatment group (INCB001158 100 mg + pembrolizumab) rather than in the actual treatment group.
