Study of Pembrolizumab (MK-3475) Compared to Platinum-Based Chemotherapies in Participants With Metastatic Non-Small Cell Lung Cancer (MK-3475-024/KEYNOTE-024)

Official Title

A Randomized Open-Label Phase III Trial of MK-3475 Versus Platinum Based Chemotherapy in 1L Subjects With PD-L1 Strong Metastatic Non-Small Cell Lung Cancer

Summary:

This is an efficacy and safety study to assess pembrolizumab (MK-3475/SCH 900475) compared to standard of care (SOC) platinum-based chemotherapies in the treatment of participants with previously untreated stage IV, programmed cell death ligand 1 (PD-L1) strong expressing Non-Small Cell Lung Cancer (NSCLC). The primary hypothesis of this study is that participants with PD-L1 strong NSCLC will have a longer Progression Free Survival (PFS), as assessed by Response Evaluation Criteria in Solid Tumours version 1.1 (RECIST 1.1) when treated with pembrolizumab than when treated with platinum-based chemotherapies.

Trial Description

Primary Outcome:

  • Progression Free Survival (PFS)
Secondary Outcome:
  • Overall Survival (OS)
  • Overall Response Rate (ORR)
Treatment Phase: Participants randomized to pembrolizumab will be treated for up to 35 cycles or until documented progressive disease (PD) occurs. Participants randomized to SOC chemotherapies will be treated with their randomized study drug for up to 4-6 cycles. After this, participants with non-squamous histologies may choose to be treated with maintenance pemetrexed for the remainder of the study or until PD occurs. For the SOC chemotherapy participants, If documented PD occurs, these participants may be eligible for the Cross-Over Phase. Cross-Over Phase: This is only applicable for participants randomized to SOC who have documented PD. Participants will be treated with pembrolizumab for the remainder of the study or until PD occurs.
