This clinical trial is focused on studying a type of lung cancer known as Large-Cell Neuroendocrine Carcinoma (LCNEC). This cancer can be in an advanced stage, either locally advanced or metastatic, meaning it has spread to other parts of the body. The study is investigating the effectiveness and safety of a treatment combination that includes the drug Durvalumab (also known by its code name MEDI 4736), along with two chemotherapy drugs, Etoposide and a type of platinum-based drug, which can be either Cisplatin or Carboplatin. These medications are given as an infusion, which means they are administered directly into the bloodstream through a vein.
The purpose of this study is to determine how well this combination of drugs works as a first-line treatment, which means it is the first treatment given for this type of cancer. Participants in the study will receive these medications over a period of time, and their health will be monitored to see how the cancer responds to the treatment. The study aims to find out if this combination can help control the cancer and improve the quality of life for patients with LCNEC.
Throughout the study, participants will receive regular check-ups and assessments to track their progress and any side effects they might experience. The study will also look at how long the treatment can keep the cancer from getting worse. This information will help doctors understand if this treatment combination is a good option for patients with advanced LCNEC.
