Brief Summary

The purpose of this study is to assess the efficacy and safety of pembrolizumab (MK-3475) in combination with boserolimab (MK-5890), MK-4830, MK-0482 in participants with advanced squamous or non-squamous NSCLC that have been previously treated with anti-PD-L1 therapy.

This study is one of three pembrolizumab substudies being conducted under one pembrolizumab umbrella master protocol (MK-3475-U01/KEYMAKER-U01).

Primary Outcome Measures
NameTimeMethod
Objective Response Rate (ORR) According to Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1)Up to approximately 24 months

ORR was defined as the percentage of participants in the analysis population who had a Complete Response (CR: Disappearance of all target lesions) or a Partial Response (PR: ≥30% decrease in the sum of diameters of target lesions) per RECIST 1.1.

Secondary Outcome Measures
NameTimeMethod
Progression-Free Survival (PFS) According to Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1)Up to approximately 24 months

PFS is defined as the time from first dose of study treatment until either the earliest date of documented progressive disease (PD) or death due to any cause, whichever occurs first. Per RECIST 1.1, PD is defined as ≥20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of ≥5 mm. The appearance of one or more new lesions is also considered PD.

Number of Participants Who Experience One or More Adverse Events (AEs)Up to approximately 27 months

An AE is defined as any unfavorable and unintended sign, symptom, disease, or worsening of preexisting condition temporally associated with study treatment and irrespective of causality to study treatment.

Number of Participants Who Discontinued Study Treatment Due to an Adverse Event (AE)Up to approximately 24 months

An AE is defined as any unfavorable and unintended sign, symptom, disease, or worsening of preexisting condition temporally associated with study treatment and irrespective of causality to study treatment.
