This clinical trial is focused on studying the effects of two medications, cobolimab and dostarlimab, in children and young adults who have been diagnosed with certain types of tumors. These tumors may have returned after treatment or have not responded to previous treatments. The study aims to understand how safe and tolerable these medications are when used together, as well as to determine the best dose for treatment. The trial will also explore how these medications work in the body and their ability to fight tumors.
The study will be conducted in two parts. In the first part, participants with advanced solid tumors will receive the combination of cobolimab and dostarlimab to assess safety and determine the appropriate dosage. In the second part, the study will focus on specific types of cancer, including melanoma and Hodgkin lymphoma, to evaluate the effectiveness of the treatment. Participants will receive the medications through an intravenous infusion, which means the medicine is given directly into a vein.
Throughout the study, participants will be closely monitored for any side effects and changes in their health. The trial will help researchers gather important information about the potential benefits and risks of using cobolimab and dostarlimab together in treating these challenging conditions. The study is expected to continue until 2030, providing valuable insights into new treatment options for young patients with difficult-to-treat tumors.
