Official title
A Randomized, Double-Blind Phase 2/3 Study of Fianlimab (Anti-LAG-3 Antibody), Cemiplimab (Anti-PD-1 Antibody), and Chemotherapy Versus Cemiplimab and Chemotherapy in First-Line Treatment of Patients With Advanced Non-Small Cell Lung Cancer (NSCLC) Irrespective of PD-L1 Expression Levels
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study is researching an investigational drug called fianlimab (also called REGN3767) with two other medications called cemiplimab and chemotherapy, individually called a "study drug" or collectively called "study drugs". 'Investigational' means that the study drug is not approved for use outside of this study by any Health Authority. Examples of chemotherapy drugs include the following: Paclitaxel plus carboplatin, and Pemetrexed plus cisplatin. The study is being conducted in patients who have advanced non-small cell lung cancer (NSCLC). The aim of the study is to see how effective the combination of fianlimab, cemiplimab, and chemotherapy is for treating advanced NSCLC, in comparison with cemiplimab and chemotherapy. 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 your blood at different times * Whether the body makes antibodies against the study drugs (which could make the drug less effective or could lead to side effects) * How administering the study drugs might improve your quality of life
