Administration of Tumor-Associated Antigen (TAA)-Specific Cytotoxic T-Lymphocytes to Pediatric Patients With Lymphomas (pediTACTAL)

H-49884 (pediTACTAL)

Investigators have previously used this sort of therapy to treat Hodgkin or non-Hodgkin lymphoma that is associated with the virus that causes infectious mononucleosis ("mono" or the "kissing disease"), Epstein-Barr virus (EBV). EBV is found in cancer cells of up to half of all patients with Hodgkin's and non-Hodgkin lymphoma. This suggests that it may play a role in causing lymphoma. The cancer cells infected by EBV are able to hide from the body's immune system and escape being killed. Investigators previously tested special white blood cells (cells that help the body fight disease and infection), called T cells. The T cells were trained to kill EBV-infected cells and were tested to see whether treatment with these cells could affect these tumors. In many patients investigators found that giving these trained T cells caused a complete or partial response. However, many patients do not have EBV found in their lymphoma cells. Therefore, investigators now want to test whether special T lymphocytes directed against other types of proteins that show on the tumor cell surface can result in similar promising results. The proteins that will be targeted in this study are called tumor-associated antigens (TAAs) - these are cell proteins that are specific to the cancer cell, so they either do not show or show up in low quantities on normal human cells. In this stage of the study, investigators will target five TAAs which commonly show on lymphoma cells , called NY-ESO-1, MAGEA4, PRAME, Survivin and SSX. Investigators will do this by using special types of T cells called cytotoxic T lymphocytes (CTLs) generated in the lab. These TM-specific T cells are an investigational product not yet approved by the U.S. Food and Drug Administration. The purpose of this stage of the study is to find out if TM-specific cytotoxic T cells are safe in children. The investigators want to learn what the side-effects are, and to see whether this therapy might help treat patients who are considered high risk for relapse of Hodgkin disease or non-Hodgkin lymphoma.

Patient/guardian given copy of informed consent. If applicable, patient assents to participation in trial. * Due to unknown effects of this therapy on a fetus, pregnant women are excluded from this research. The male partner should use a condom.
