Brief Summary:

The purpose of this study is to assess the efficacy and safety of pembrolizumab (MK-3475) in combination with MK-4830 in treatment-naïve participants with advanced squamous or non-squamous NSCLC that is PD-L1 positive.

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

The pembrolizumab+MK-0482 arm was added with Amendment 6.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Objective Response Rate (ORR) According to Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) [ Time Frame: 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 :
  1. Progression-Free Survival (PFS) According to Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) [ Time Frame: 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.

  2. Number of Participants Who Experience One or More Adverse Events (AEs) [ Time Frame: 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.

  3. Number of Participants Who Discontinued Study Treatment Due to an Adverse Event (AE) [ Time Frame: 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.
