Research Study Utilizing Expanded Multi-antigen Specific Lymphocytes for the Treatment of Solid Tumors

Patients with high-risk solid tumors, those that are refractory to standard up front therapy or relapse after completion of therapy, have a very poor prognosis despite attempts to induce remission with salvage regimen. Novel therapies are critical for this patient population with high-risk cancer. The ability of tumors to be recognized and lysed by the immune system offers a unique opportunity to aid in tumor eradication by expanding and activating these anti-tumor cells. Through this ability to harness sophisticated and specific immunotherapy, residual or relapsed disease that is resistant to chemotherapy and/or radiotherapy could be eradicated. Prior studies have suggested both safety of expanded specific T cells and efficacy in the setting of melanoma, lymphoma or viral eradication. While this therapy has previously been limited by the versatility of the tumor to down-regulate antigens and evade a single immune-target, the use of multi-antigen specific T cells may permit better and more durable anti-tumor immunity. Thus, the investigators propose to infuse these specific multi-antigen anti-tumor T lymphocytes into patients with high risk solid tumors. This trial will be conducted to demonstrate safety of these cells and generate efficacy and biology data that may be important for future studies that may enhance tumor immunotherapy.
