Platinum-based chemotherapy

This study is focused on patients with non-small cell lung cancer (NSCLC) and have been prescribed a cemiplimab (Libtayo®) based treatment regimen under standard care. The goal of this study is to learn more about the use, benefits, and safety of cemiplimab based treatment regimens in participants with NSCLC.

This study will enroll adult participants with early-stage (stage II-IIIB) non-small cell lung cancer for whom surgery is planned. The aim is to find out whether an investigational treatment (consisting of the immunotherapy drug cemiplimab plus chemotherapy plus a third drug) works better than cemiplimab plus chemotherapy without the additional drug. The study is also looking at several other research questions, including: * What are the side effects associated with the investigational treatments in comparison to the control treatment? * Do the investigational treatments or the control treatment have an effect on the type of surgery that is performed? * How much of the study drug(s) are in the blood at a given time? * Does the body make antibodies against the study drug(s) (which could make the drug(s) less effective or could lead to side effects)?
