This trial will evaluate, in patients with metastatic prostate cancer, the tolerability, toxicities, efficacy, and immunologic effects of repeated vaccinations with a recombinant vaccinia virus that contains the Prostate Specific Antigen gene (PROSTVAC). Patients with PSA-expressing adenocarcinoma of the prostate will be evaluated for eligibility that includes a history of prior vaccinia (as vaccine against smallpox) and immunocompetence. We completed a phase I trial investigating the use of rV-CEA in adenocarcinomas of the GI tract, lung and breast. The toxicities encountered are local rea...
