Lymphodepletion Chemotherapy, CD40L-Augmented Tumor Infiltrating Lymphocytes, and Interleukin-2 for the Treatment of Advanced, Unresectable, and Metastatic Melanoma

Trial Status: active

This phase I/II trial tests the safety, side effects, and how well lymphodepletion chemotherapy with cyclophosphamide and fludarabine followed by CD40L-augmented tumor infiltrating lymphocytes (TILs) and interleukin-2 works in treating melanoma that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced), that cannot be removed by surgery (unresectable), or that has spread from where it first started (primary site) to other places in the body (metastatic). Lymphodepletion chemotherapy with cyclophosphamide and fludarabine is used to temporarily reduce the number of normal lymphocytes, or white blood cells, circulating in the body so that there will be more “space” for the TIL infusion. TIL infusion involves the use of special immune cells called T-cells. A T-cell is a type of lymphocyte. Lymphocytes protect the body from viral infections, help other cells fight bacterial and fungal infections, produce antibodies, fight cancers, and coordinate the activities of other cells in the immune system. These special immune T-cells will be taken from a sample of tumor tissue from the patient that is surgically removed. Certain parts of these cells will be multiplied, or grown, in the laboratory, and the manufactured CD40L-augmented TIL will then be given back to the patient by infusion. Interleukin-2 is a drug used to help the body’s response to treatment on the immune system. The combination of lymphodepletion chemotherapy, TIL infusion, and interleukin-2 may help treat advanced, unresectable, and metastatic melanoma.
