This clinical trial is focused on studying the treatment of extensive-stage small cell lung cancer (ES-SCLC), a type of lung cancer that has spread widely throughout the body. The study aims to evaluate the effectiveness and safety of a combination of treatments for patients who are receiving their first line of therapy for this condition. The treatments being tested include a combination of Pembrolizumab, also known as Keytruda, with other investigational agents such as Lenvatinib (code name MK-7902), MK-4830, and Boserolimab (code name MK-5890), along with standard chemotherapy drugs like Etoposide, Cisplatin, or Carboplatin.
The purpose of this study is to determine how well these treatments work together in controlling the cancer and to assess their safety. Participants in the study will receive these medications either through an intravenous infusion, which is a method of delivering medicine directly into the bloodstream, or orally in the form of capsules. The study will monitor the participants over a period to see how their cancer responds to the treatment and to check for any side effects.
Throughout the study, participants will undergo regular assessments to track the progress of their cancer and to ensure their safety. These assessments will help researchers understand the potential benefits and risks of using these combinations of treatments for patients with extensive-stage small cell lung cancer. The study is designed to provide valuable information that could lead to improved treatment options for this challenging condition.
