This clinical trial is focused on treating patients with advanced melanoma or head and neck squamous cell carcinoma (HNSCC). The study involves a treatment using a special type of immune cells called MC2 TCR T cells, which are engineered to target cancer cells. These cells are combined with an epigenetic drug treatment, which involves using drugs that can change the activity of genes without altering the DNA sequence. The purpose of the study is to evaluate the safety and effectiveness of this combination treatment.
Participants in the study will receive the treatment through intravenous administration, meaning it will be delivered directly into the bloodstream. The study is divided into two phases. In the first phase, the focus is on determining the safety and the best dose of the MC2 TCR T cells when used with the epigenetic drug. The second phase will assess how well the treatment works in shrinking or controlling the cancer. Throughout the study, doctors will monitor for any side effects and measure how the cancer responds to the treatment.
The trial aims to find out if this new approach can be a viable option for patients with these types of cancer, especially those who have not responded to standard treatments. By using the patient’s own immune cells, which are modified to better fight the cancer, the study hopes to offer a more personalized treatment option. The results will help determine if this therapy can be used more widely in the future for treating advanced melanoma and HNSCC.
