This clinical trial is focused on studying a type of lung cancer known as non-small cell lung cancer (NSCLC) that has returned or not responded to previous treatments. The study is testing two treatments: GEN1046, also known as Acasunlimab, and Pembrolizumab, which is marketed under the name Keytruda. GEN1046 is a special type of protein designed to help the immune system fight cancer, while Pembrolizumab is a medication that helps the immune system detect and attack cancer cells.
The purpose of the study is to evaluate how well these treatments work, both when used alone and when combined, in patients with this type of lung cancer. Participants will receive the treatments through an infusion, which means the medication is given directly into the bloodstream through a vein. The study will monitor the effects of the treatments over a period of time to see how the cancer responds and to check for any side effects.
Throughout the study, researchers will look at various outcomes, such as how long the cancer stays under control, how long patients live, and any changes in the size of the cancer. The study will also track any side effects or changes in laboratory tests to ensure the safety of the participants. This research aims to provide more information about the effectiveness and safety of these treatments for people with non-small cell lung cancer.
