This clinical trial is focused on studying a type of lung cancer known as Stage III non-small cell lung cancer (NSCLC), which is advanced and cannot be removed by surgery. The study will explore a new treatment approach using a drug called JNJ-90301900, also known as hafnium oxide, which is given as an injection directly into the tumor. This drug is being tested to see if it can enhance the effects of radiation therapy, a method known as a radioenhancer.
The purpose of the study is to determine if adding JNJ-90301900 to the standard treatment of chemotherapy and radiation, followed by a medication called durvalumab, can improve the response rate in patients with this type of lung cancer. Durvalumab is a type of immunotherapy, which helps the body’s immune system fight cancer. The study will compare the effects of this new combination treatment to the standard treatment alone.
Participants in the study will receive the combination of JNJ-90301900, chemotherapy, and radiation, followed by durvalumab. The study will monitor how well the cancer responds to this treatment over time. The trial is expected to continue for several years to gather enough information about the effectiveness and safety of this new treatment approach.
