What was measured

Selected events that occurred during DLT observation period were considered as DLT unless due to PD or to a cause obviously unrelated to pegenzileukin. Selected events included: grade (G) 4 neutropenia for \>=7 consecutive days, G3 or 4 neutropenia complicated by fever or microbiologically or radiographically documented infection, G3 or 4 thrombocytopenia associated with clinically significant bleeding that required clinical intervention; G3 or above alanine aminotransferase or aspartate aminotransferase in combination with a bilirubin \>2 times upper limit of normal with no evidence of cholestasis or another cause such as viral infection or other drugs;G3 or above vascular leak syndrome, hypotension, and cytokine release syndrome;any other G3; G3 or 4 non-hematologic laboratory value; any death not clearly due to the underlying disease or extraneous causes;any toxicity that required permanent discontinuation of the study treatment(s).

Analysis population: The DLT-evaluable population consisted of all exposed participants in the safety run-in who had been observed for at least 21 days. Any participants who had experienced a DLT during DLT observation period were also DLT-evaluable.

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.

Cohort B1: NSCLC:Pegenzileukin 24 μg/kg+Pembrolizumab as 2/3L Therapy

Participants with NSCLC for whom SOC was not in their best interest or where no SOC was established 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 2/3L therapy), until PD, unacceptable AE or other full permanent discontinuation criteria was met or completion of Cycle 35.

Cohort C1:Mesothelioma:Pegenzileukin 24 μg /kg+Pembrolizumab as 2/3L Therapy

Participants with mesothelioma who had no SOC established and had experienced PD during or after at least one but no more than 2 prior regimens 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 2/3L therapy), until PD, unacceptable AE or other full permanent discontinuation criteria was met or completion of Cycle 35.
