Official title
Tumor Associated Antigen (TAA) Specific Cytotoxic T Lymphocytes Administered in Patients With Breast Cancer
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Status - CLOSED TO PATIENT ENROLLMENT (CNPE) The study is being conducted in patients in which breast cancer has come back after standard treatment. Volunteers in this research study are treated using special immune system cells called tumor-associated antigen (TAA)-specific cytotoxic T lymphocytes, a new experimental therapy. The proteins that investigators are targeting in this study are called tumor-associated antigens (TAAs). These are cell proteins that are specific to the cancer cell. They do not show, or they show up in low quantities, on normal human cells. In this study, investigators target five common TAAs. They are called NY-ESO-1, MAGEA4, PRAME, Survivin and SSX2. On a different study, patients have been treated and so far this treatment has shown to be safe. Investigators now want to try this treatment in patients with breast cancer. These TAA-specific cytotoxic T lymphocytes (TAA-CTLs) are an investigational product not approved by the Food and Drug Administration. The purpose of this study is to determine the clinical efficacy of TAA-specific CTLs, to learn what the side-effects are, and to see whether this therapy might help patients with breast cancer.
