This clinical trial is focused on studying treatments for solid tumors, which are abnormal masses of tissue that usually do not contain cysts or liquid areas. The study involves testing genetically modified T-cells, which are a type of immune cell taken from the patient, altered in a lab to better recognize and attack cancer cells, and then infused back into the patient. The treatments being tested include IMA203 and IMA203CD8, both of which are forms of cell therapy, as well as a medication called nivolumab, also known by its code name BMS936558, which is used to help the immune system fight cancer.
The purpose of the study is to evaluate the safety and effectiveness of these treatments, either alone or in combination. The study is divided into two phases. In the first phase, researchers will assess how safe and tolerable the treatments are and determine the best dose to use. In the second phase, the focus will be on how well the treatment works against the tumors. Participants will receive the treatments through an intravenous infusion, which means the medication is given directly into a vein.
Throughout the study, researchers will monitor participants for any side effects and measure how the tumors respond to the treatment. The study aims to find out if these new treatments can help control or reduce the size of the tumors in patients with solid tumors that have returned or are resistant to other treatments. The trial is expected to continue until the end of 2028.
