Brief Summary:
The main purpose of this study is to compare pembrolizumab/vibostolimab coformulation (MK-7684A) plus docetaxel or pembrolizumab/vibostolimab coformulation to normal saline placebo plus docetaxel. Participants with metastatic non-small cell lung cancer (NSCLC) and progressive disease (PD) after platinum doublet chemotherapy and treatment with one prior anti- programmed cell death 1 (PD-1)/ programmed cell death ligand 1(PD-L1) monoclonal antibody (mAb). MK-7684A is a coformulation product of pembrolizumab/vibostolimab. The dual primary hypotheses of the study are pembrolizumab/vibostolimab coformulation plus docetaxel and pembrolizumab/vibostolimab coformulation is superior to normal saline placebo plus docetaxel with respect to progression free survival (PFS) per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) by blinded independent central review (BICR).

Primary Outcome Measures :
  1. Progression Free Survival (PFS) per Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1) by Blinded Independent Central Review (BICR) Assessment [ Time Frame: Up to approximately 27 months ]
    PFS is defined as the time from randomization to the first documented disease progression (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. PFS as assessed by BICR will be presented


Secondary Outcome Measures :
  1. Objective Response (OR) per RECIST 1.1 by BICR Assessment [ Time Frame: Up to approximately 27 months ]
    OR is defined as a confirmed complete response (CR: Disappearance of all target lesions) or a partial response (PR: At least a 30% decrease in the sum of diameters of target lesions) per RECIST 1.1. The percentage of participants who experience a CR or PR as assessed by BICR based on RECIST 1.1 will be presented.

  2. Overall Survival (OS) [ Time Frame: Up to approximately 77 months ]
    OS is defined as the time from randomization to the date of death due to any cause.

  3. Duration of Response (DOR) per RECIST 1.1 by BICR Assessment [ Time Frame: Up to approximately 77 months ]
    For participants who demonstrate a confirmed CR (Disappearance of all target lesions) or confirmed PR (At least a 30% decrease in the sum of diameters of target lesions) per RECIST 1.1, DOR is defined as the time from first documented evidence of CR or PR until disease progression (PD) or death. Per RECIST 1.1, PD is defined as at least a 20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum must also have demonstrated an absolute increase of at least 5 mm. The appearance of one or more new lesions was also considered PD. The DOR as assessed by BICR will be presented.

  4. Number of Participants Who Experienced an Adverse Event (AE) [ Time Frame: Up to approximately 77 months ]
    An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. Number of participants who experience an AE will be reported.

  5. Number of Participants Who Discontinued Study Treatment Due to an AE [ Time Frame: Up to approximately 37 months ]
    An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. Number of participants who discontinue study treatment due to an AE will be reported.
