Study Description

Brief Summary:

A Phase II Randomized, Double-Blind, Placebo-Controlled Study of Pembrolizumab Maintenance Following First-Line Platinum Based Chemotherapy in Patients with Metastatic Squamous - Non-Small Cell Lung Cancer (sNSCLC).

Condition or disease	Intervention/treatment	Phase
Metastatic Squamous Non-small Cell Lung Cancer	Drug: Pembrolizumab; Drug: Placebo	Phase 2

Detailed Description:

Patients with squamous non-small cell lung cancer and an ECOG of 0-1 who received a first-line therapy with Cis-/Carboplatin for at least 2 cycles that had at least Complete Response (CR) / Partial Response (PR) / Stable Disease (SD) according to Response Evaluation Criteria in Solid Tumors (RECIST) v 1.1 will be randomized either to Arm A Pembrolizumab or to Arm B Placebo for a maximum of 2 years or until progressive disease or unacceptable toxicity.

The aim is to investigate the efficacy of Pembrolizumab vs. placebo in terms of progression-free survival in patients with metastatic squamous, non-small cell lung cancer. Furthermore to evaluate tumor response, survival, tolerability and safety as well as quality of life of patients receiving Pembrolizumab.

3. PD-L1 expression in tumor samples [ Time Frame: samples at baseline taken ; collection up to 35 months ]
   assessment of the prognostic value of PD-L1 expression in tumor samples obtained prior to study enrollment

   Safety (intensity and incidence of adverse events, graded according to US NCI Common terminology criteria for adverse events (CTCAE) Version 4.03)
5. Functional Assessment of Cancer Therapy for patients with Lung cancer [ Time Frame: every 6 weeks until EOT for approx. 7 months ]
