Title: A Randomized, Double-Blind, Phase III Study of Carboplatin-Paclitaxel/Nab-Paclitaxel Chemotherapy With or Without Pembrolizumab (MK-3475) in First Line Metastatic Squamous Non-small Cell Lung Cancer Subjects (KEYNOTE-407)
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.
