What was measured

BOR was evaluated per RECIST v1.1. CR: disappearance of all target and non-target lesions and no appearance of any new lesions. Any pathological lymph nodes (whether target or non-target) must have a reduction in the short axis to \<10 mm. PR: complete disappearance or at least a 30% decrease in the sum of the diameters of target lesions, taking as a reference the baseline sum diameters, no new lesions, and no progression of non-target lesions. Stable disease (SD): no change in target lesions to qualify for CR, PR, or progressive disease (PD). PD: progression of a target or non-target lesion or presence of a new lesion. Missing: participant had a missing BOR because there were no post-Baseline tumor assessments. Pleural mesothelioma was evaluated using modified RECIST criteria.

Analysis population: REEP. 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. It was pre-specified to combine Part 1c and Part 3 participants for efficacy analysis based on planned comparable dosing according to renal function. Two participants evaluable for PFS were not evaluable for response.

BOR was evaluated per RECIST v1.1. CR: disappearance of all target and non-target lesions and no appearance of any new lesions. Any pathological lymph nodes (whether target or non-target) must have a reduction in the short axis to \<10 mm. PR: complete disappearance or at least a 30% decrease in the sum of the diameters of target lesions, taking as a reference the baseline sum diameters, no new lesions, and no progression of non-target lesions. Stable disease (SD): no change in target lesions to qualify for CR, PR, or progressive disease (PD). PD: progression of a target or non-target lesion or presence of a new lesion. Missing: participant had a missing BOR because there were no post-Baseline tumor assessments. Pleural mesothelioma was evaluated using modified RECIST criteria.
