OUTLINE: Patients undergo leukapheresis to obtain peripheral blood mononuclear cells and then CD8+ cytotoxic T-lymphocyte (CTL) clones are generated ex vivo. Patients receive cellular adoptive immunotherapy comprising autologous CD8+ CTL clones targeting cancer testis antigens IV over 30 minutes on day 1. Patients also receive interleukin-2 subcutaneously every 12 hours on days 1-14 of courses 2-4. Treatment repeats every 3 weeks for 4 courses in the absence of disease progression or unacceptable toxicity. Patients who demonstrate a clinical response after completion of the fourth course are eligible to receive additional T-cell infusions.
