Efficacy and Safety of Pembrolizumab (MK-3475) With Platinum Doublet Chemotherapy as Neoadjuvant/Adjuvant Therapy for Participants With Resectable Stage IIB or IIIA Non-small Cell Lung Cancer (MK-3475-671/KEYNOTE-671)

Official Title

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)

Summary:

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 Tumours Version 1.1 (RECIST 1.1) assessed by blinded independent central review (BICR); and 2) overall survival (OS).

Trial Description

Primary Outcome:

  • Event Free Survival (EFS)
  • Overall Survival (OS)
Secondary Outcome:

  • Pathological Complete Response (pCR) Rate
  • Global Health Status/Quality of Life (GHS/QoL) Score using the European Organization for Research and Treatment (EORTC) QoL Questionnaire (QLQ-C30)
  • Adverse Events (AEs)
  • Perioperative Complications
  • Treatment Discontinuations Due to AEs
