The primary objectives of the study are:
- To compare the overall survival (OS) of cemiplimab versus standard-of-care platinum-based chemotherapies in the first-line treatment of patients with advanced or metastatic non-small cell lung cancer (NSCLC) whose tumors express PD-L1 in ≥50% of tumor cells
- To compare the progression-free survival (PFS) of cemiplimab versus standard-of-care platinum-based chemotherapies in the first-line treatment of patients with advanced or metastatic NSCLC whose tumors express PD-L1 in ≥50% of tumor cells
The key secondary objective of the study is to compare the objective response rate (ORR) of cemiplimab versus platinum-based chemotherapies

- Overall survival (OS) [ Time Frame: From date of randomization until the date of death, assessed up to 68 months ]
- Progression-free survival (PFS) as assessed by a blinded Independent review committee (IRC) using RECIST 1.1 [ Time Frame: From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 68 months ]PFS as assessed by a blinded IRC using RECIST 1.1.
- Objective response rates (ORR) [ Time Frame: From date of randomization to the date of the first objectively documented progression or the date of subsequent anti-cancer therapy, whichever comes first, up to 68 months ]The number of patients with a best overall response (BOR) of confirmed Complete Response (CR) or Partial Response (PR) divided by the number of patients in the efficacy analysis set
- Best overall response (BOR) [ Time Frame: From date of randomization until the date of first documented progression or the date of subsequent anti-cancer therapy, whichever came first, assessed up to 68 months ]The BOR, as determined by the IRC per RECIST 1.1
- Compare the duration of response (DOR) of cemiplimab versus platinum based chemotherapies [ Time Frame: From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 68 months ]Duration of response will be defined as the time between the date of first response (CR or PR) to the date of the first documented tumor progression (per RECIST 1.1) or the date of subsequent anti-cancer therapy or death due to any cause, whichever comes first
