Recruitment Details | |
Pre-assignment Details | Eligible participants were randomized in a 1:1 ratio to receive cemiplimab or investigator choice of chemotherapy (control treatment determined before randomization by investigator from options per protocol). Randomization was stratified according to histologic type (squamous-cell carcinoma or adenocarcinoma [including adenosquamous carcinoma]), region (N. America/Asia/rest of world), previous bevacizumab exposure (y/n), & Eastern Cooperative Oncology Group (ECOG) performance-status score (0/1). |
Arm/Group Title | Cemiplimab | Investigator Choice (IC) Chemotherapy |
---|---|---|
Arm/Group Description | Participants received a fixed dose of 350 milligrams (mg) of cemiplimab intravenous (IV) infusion on Day 1 of every 3 weeks (Q3W) for up to 96 weeks (up to 16 cycles of 6 weeks each) or until progression of disease or unacceptable toxicity, voluntary withdrawal from the study. | Participants received IC of chemotherapy (options listed by class): (1) Antifolate: pemetrexed 500 mg per meter square (mg/m^2) on Day 1; (2) Topoisomerase 1 inhibitor: topotecan 1 mg/m^2 daily for 5 days, starting on Day 1 or irinotecan 100 mg/m^2 weekly (Days 1, 8, 15 and 22), followed by 10 to 14 days rest, for a 42-day (6-week) cycle; (3) Nucleoside analogue: gemcitabine 1000 mg/m^2 on Days 1 and 8; (4) Vinca alkaloid: vinorelbine 30 mg/m^2 IV infusion based on body surface area for Q3W up to 96 weeks (up to 16 cycles of 6 weeks each) or until progression of disease or unacceptable toxicity, voluntary withdrawal from the study. |
