A Phase III, Randomized, Double-blind Trial of Platinum Doublet Chemotherapy +/-Pembrolizumab (MK-3475) as Neoadjuvant/Adjuvant Therapy for Participants with Resectable Stage IIB or IIIA Non-small Cell Lung Cancer (NSCLC) (KEYNOTE-671)

General Information

Age Group

Adult

Status

Recruiting

Protocol Number

NCT03425643

Background Information

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 IIB or IIIA 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 blinded central pathologist or by imaging using Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) assessed by blinded independent central review (BICR); and 2) overall survival (OS).
