E7 TCR-T Cells with Aldesleukin for the Treatment of Recurrent/Refractory or Metastatic HPV-16 Positive Cancers

Trial Status: active

This phase II trial tests how well E7 T cell receptor (TCR)-T cells work in treating patients with human papillomavirus (HPV)-16 positive cancers that has come back (after a period of improvement) (recurrent), does not respond to treatment (refractory), or has spread from where it first started (primary site) to other places in the body (metastatic). T cells can be directed against diverse tumors through TCR gene therapy in which peripheral blood T cells are modified to express a TCR targeting a specific tumor protein. This trial is studying TCR gene therapy directed against the oncoprotein E7 which is expressed by HPV positive tumor cells, and is absent from healthy human tissues. To generate E7 TCR-T cells, patients undergo leukapheresis to collect T cells from the patient's blood. The T cells are then genetically engineered in the laboratory to have a TCR that lets them target E7. Genetic engineering is performed using a retrovirus, a type of virus that can move genes into cells. Before the manufactured cells are given, patients receive chemotherapy to prepare the body for the cells. Chemotherapy drugs, such as cyclophosphamide and fludarabine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. After the T cells are given, patients also receive aldesleukin to make the E7 TCR-T cells work better in the body. Immunotherapy with aldesleukin, may induce changes in body's immune system and may interfere with the ability of tumor cells to grow and spread. The administration of tumor-specific T-cells is a promising approach to cancer treatment that could mediate durable, complete regression of HPV-16 positive cancers.
