What was measured

ORR was defined as the percentage of participants who had a confirmed complete response (CR) or partial response (PR) as per Response Evaluation Criteria in Solid Tumors (RECIST) version (v) 1.1. CR. CR was defined as the disappearance of all target lesions, any pathological lymph nodes (whether target or non-target) with reduction in short axis to \<10 millimeter (mm) (\<1 centimeter \[cm\]). PR was defined as at least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum diameters.

Analysis population: The efficacy population consisted of all participants from the exposed population with at least one evaluable post-baseline tumor assessment or who permanently discontinued study treatment.

Groups in this outcome

Cohort A1:NSCLC, PD-L1 TPS >=50%:Pegenzileukin 24 μg/kg + Pembrolizumab as 1L Therapy

Participants with previously untreated Stage IV NSCLC and PD-L1 TPS of \>=50% were included in this cohort. Participants received pegenzileukin 24 μg/kg along with pembrolizumab 200 mg via IV infusion over 30 minutes q3w on Day 1 of each cycle (each cycle is 21 days) (as 1L therapy), until PD, unacceptable AE or other full permanent discontinuation criteria was met or completion of Cycle 35.

Cohort A2:NSCLC, PD-L1 TPS 1%-49%:Pegenzileukin 24 μg/kg+Pembrolizumab as 1L Therapy

Participants with previously untreated Stage IV NSCLC and PD-L1 TPS of 1%-49% were included in this cohort. Participants received pegenzileukin 24 μg/kg along with pembrolizumab 200 mg via IV infusion over 30 minutes q3w on Day 1 of each cycle (each cycle is 21 days) (as 1L therapy), until PD, unacceptable AE or other full permanent discontinuation criteria was met or completion of Cycle 35.
