Brief summary

This study is researching an experimental drug called fianlimab (also called REGN3767) with two other medications called cemiplimab and platinum-doublet chemotherapy, individually called a "study drug" or collectively called "study drugs", when combined in this study. The study is being conducted in patients who have resectable stage II to IIIB (N2) non-small cell lung cancer (NSCLC) that can be treated with surgery. The aim of the study is to see how effective the combination of fianlimab, cemiplimab, and chemotherapy is in comparison with cemiplimab and chemotherapy as peri-operative therapy in participants with NSCLC. The study is looking at several other research questions, including: * What side effects may happen from taking the study drugs * How much of each study drug is in the blood at different times * Whether the body makes antibodies against the study drugs (which could make the drugs less effective or could lead to side effects) * How administering the study drugs might affect quality of life

Overall change in patient-reported global health status/QoL per European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30)Up to 5 yearsEORTC-QLQ-C30 is a 30-item subject self-report questionnaire composed of both multi-item and single scales, including a global health status/quality of life (GHS/QoL) scale. Participants rate items on a four-point scale, with 1 as "not at all" and 4 as "very much." A change of 5 - 10 points is considered a small change. A change of 10 - 20 points is considered a moderate change.
Overall change in patient-reported physical functioning per EORTC QLQ-C30Up to 5 years
Overall change in patient-reported role functioning per EORTC QLQ-C30Up to 5 years
Overall change in patient-reported chest pain per European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Lung Cancer 13 (EORTC QLQ-LC13)Up to 5 yearsThe EORTC QLQ-LC13 is a lung cancer-specific supplemental questionnaire used in combination with the EORTC QLQ-C30. Participant responses to the question "Have you had pain in your chest?" are scored on a 4-point scale (1=Not at All to 4=Very Much). Using linear transformation, raw scores are standardized, so that scores range from 0 to 100. The change from baseline in chest pain (EORTC QLQ-LC13 Item 40) score will be presented. A lower score indicates a better outcome.

Each dimension is rated on a 5-level scale: no problems, slight problems, moderate problems, severe problems and extreme problems
Change in patient-reported general health status per Visual analogue scale (VAS) scoresUp to 5 yearsThe EQ-5D-5L VAS records the respondent's self-rated health on a 10 centimeter (cm) vertical, visual analogue scale. It is rated by the respondent on a scale 0 to 100, with 0 being "the worst health you can imagine" and 100 being "the best health you can imagine".
