Clinical Trial Summary

In this China extension study, carboplatin and paclitaxel or nano particle albumin-bound paclitaxel (nab-paclitaxel) with or without pembrolizumab (MK-3475, KEYTRUDA®) will be administered to Chinese 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) in Chinese participants. 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.
