Study of Pembrolizumab (MK-3475) Versus Platinum-Based Chemotherapy for Participants With Programmed Cell Death-Ligand 1 (PD-L1)-Positive Advanced or Metastatic Non-Small Cell Lung Cancer (MK-3475-042/KEYNOTE-042)

A Randomized, Open Label, Phase III Study of Overall Survival Comparing Pembrolizumab (MK-3475) Versus Platinum Based Chemotherapy in Treatment Naïve Subjects With PD-L1 Positive Advanced or Metastatic Non-Small Cell Lung Cancer (Keynote 042)

View on ClinicalTrials.gov

Summary

In this study, participants with programmed cell death ligand 1 (PD-L1)-positive non-small cell lung cancer (NSCLC) will be randomized to receive single agent pembrolizumab for up to 35 treatments or standard of care (SOC) platinum-based chemotherapy (carboplatin + paclitaxel or carboplatin + pemetrexed for 4 to 6 21-day cycles). Participants in the platinum-based chemotherapy arms with non-squamous tumor histologies may receive pemetrexed maintenance therapy after the 4 to 6 cycles of chemotherapy. The primary study hypothesis is that pembrolizumab prolongs overall survival (OS) compared to SOC chemotherapy.

Detailed Description

Pembrolizumab-treated participants, who attain a confirmed complete response (CR) or who stop trial treatment after 35 administrations of study medication for reasons other than disease progression or intolerability, may consider stopping trial treatment. These participants may be eligible for re-treatment with pembrolizumab monotherapy after they have experienced radiographic disease according to protocol-defined criteria. Response or progression in the Second Course Phase will not count towards the objective response rate (ORR) and progression free survival (PFS) endpoints in this trial. The global study for MK-3475-042 enrolled 1274 participants. Of the 1274 total participants enrolled in the global study, 92 were also enrolled in the China extension study for MK-3475-042 (NCT03850444).

•Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 or 1
•Adequate organ function
•No prior malignancy, with the exception of basal cell carcinoma of the skin, superficial bladder cancer, squamous cell carcinoma of the skin, or in situ cancer, or has undergone potentially curative therapy with no evidence of that disease recurrence for 5 years since initiation of that therapy
•Submission of formalin-fixed diagnostic tumor tissue (in the case of participants having received adjuvant systemic therapy, the tissue should be taken after completion of this therapy)
•Female participants of childbearing potential must have a negative urine or serum pregnancy test and must be willing to use two adequate barrier methods of contraception or a barrier method plus a hormonal method starting with the screening visit through 120 days after the last dose of pembrolizumab or 180 days after the last dose of chemotherapeutic agents used in the study

Exclusion Criteria

•Epidermal growth factor receptor (EGFR)-sensitizing mutation and/or is echinoderm microtubule-associated protein-like 4(EML4) gene/anaplastic lymphoma kinase (ALK) gene fusion positive
•Currently participating or has participated in a study of an investigational agent or using an investigational device within 4 weeks of the first dose of study therapy
•No tumor specimen evaluable for PD-L1 expression by the central study laboratory
•Squamous histology and received carboplatin in combination with paclitaxel in the adjuvant setting
•Is receiving systemic steroid therapy ≤3 days prior to the first dose of study therapy or receiving any other form of immunosuppressive medication with the exception of daily steroid replacement therapy
•The NSCLC can be treated with curative intent with either surgical resection and/or chemoradiation
•Expected to require any other form of systemic or localized antineoplastic therapy while on study
•Any prior systemic cytotoxic chemotherapy, biological therapy or major surgery within 3 weeks of the first dose of study therapy; received lung radiation therapy \>30 Gy within 6 months of the first dose of study therapy
•Prior therapy with an anti-PD-1, anti-PD-L1, anti-PD-L2, anti-CD137, or anti-cytotoxic T-lymphocyte-associated antigen-4 (CTLA-4) antibody (including ipilimumab or any other antibody or drug specifically targeting T-cell co-stimulation or checkpoint pathways)
