Overview
Brief Summary
This is a study of carboplatin and paclitaxel or nano particle albumin-bound paclitaxel (nab-paclitaxel) with or without pembrolizumab (MK-3475, KEYTRUDA®) in adults with first line metastatic squamous non-small cell lung cancer (NSCLC).
The primary hypotheses are that treatment with pembrolizumab prolongs: 1) Progression-free Survival (PFS) by Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1) as assessed by a blinded central imaging vendor compared to placebo, and 2) Overall Survival (OS).
After analysis of interim results was conducted, the protocol was amended (Amendment 5) to allow participants the option to discontinue placebo in the control arm and to switch to pembrolizumab in the event of documented progressive disease as assessed by central review.

Outcomes
Primary Outcomes
Progression-free Survival (PFS) as Assessed by Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1)
Time Frame: Up to approximately 19 months
PFS was defined as the time from randomization to the first documented progressive disease (PD) or death due to any cause, whichever occurred first. Per Response Criteria in Solid Tumors version 1.1 (RECIST 1.1), PD was defined as ≥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 ≥5 mm. Note: The appearance of ≥1 new lesions was also considered PD. PFS as assessed by blinded independent central review per RECIST 1.1 is presented.
Overall Survival (OS)
Time Frame: Up to approximately 19 months
OS was defined as the time from randomization to death due to any cause. OS is presented.
