TAA-Specific CTLS for Solid Tumors (TACTASOM)

This is a clinical trial for patients with a solid tumor which has come back, or may come back, or has not gone away after treatment, including the standard treatment we know for these diseases. This is a study using special immune system cells called tumor-associated antigen (TAA)-specific cytotoxic T lymphocytes, a new experimental therapy. The proteins that the investigators are targeting 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 study, the investigators target five common TAAs called NY-ESO-1, MAGEA4, PRAME, Survivin and SSX. On a different study, patients have been treated and so far this treatment has shown to be safe. The investigators now want to try this treatment in patients with solid tumors. This protocol is designed as a Phase I dose-escalation study.
