This clinical trial is focused on studying two types of blood cancers: Classical Hodgkin Lymphoma and Non-Hodgkin Lymphoma. These are conditions where the body’s lymphatic system, which is part of the immune system, develops cancerous cells. The study is testing a combination of two medications, Relatlimab and Nivolumab, to see how safe and effective they are for treating these cancers in children and young adults. Relatlimab is given as an injection, while Nivolumab is provided as an infusion, both administered directly into the bloodstream.
The purpose of the study is to understand how well these medications work together and how the body handles them. Participants will receive the treatment and be monitored for any side effects and how their cancer responds. The study is divided into two parts: the first part focuses on children under 18 years old to determine the safest dose, and the second part includes young adults up to 30 years old to assess how well the treatment works based on the findings from the first part.
Throughout the study, participants will undergo regular check-ups and tests to monitor their health and the progress of their treatment. The goal is to find a new, effective treatment option for those whose cancer has returned or not responded to standard therapies. This study is an important step in exploring new ways to help young patients with these challenging conditions.
