Trial Summary

What is the purpose of this trial?

This trial will evaluate the safety and efficacy of pembrolizumab (MK-3475) in combination with platinum doublet neoadjuvant chemotherapy (NAC) before surgery \[neoadjuvant phase\], followed by pembrolizumab alone after surgery \[adjuvant phase\] in participants with resectable stage II, IIIA, and resectable IIIB (T3-4N2) non-small cell lung cancer (NSCLC). The primary hypotheses of this study are that neoadjuvant pembrolizumab (vs. placebo) in combination with NAC, followed by surgery and adjuvant pembrolizumab (vs. placebo) will improve: 1) event free survival (EFS) by biopsy assessed by local pathologist or by investigator-assessed imaging using Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1); and 2) overall survival (OS).

Interventions

  • Cisplatin (Platinum-based Chemotherapy)
  • Gemcitabine (Platinum-based Chemotherapy)
  • Pembrolizumab (Monoclonal Antibodies)
  • Pemetrexed (Platinum-based Chemotherapy)
Trial OverviewThe trial tests pembrolizumab combined with platinum doublet chemotherapy before surgery (neoadjuvant phase) and pembrolizumab alone after surgery (adjuvant phase). It aims to improve event-free survival and overall survival compared to placebo. Patients are randomly assigned to receive either pembrolizumab or placebo alongside standard chemotherapy before and after surgical removal of the lung tumor.
