Each subject will be given 7 initial injections in a fixed dose amount. The first 4 doses will be given at 2-week intervals (Weeks 0, 2, 4 and 6); the last 3 doses will be given at 4-week intervals (Weeks 10, 14, and 18). Those patients who exhibit stable disease, partial response or complete response after 7 injections will be given 4 more vaccinations. Each of these additional 4 vaccinations will be given 3 months apart (Weeks 36, 48, 72 and 96). Scans and re-staging tests will be performed at scheduled intervals throughout the study.
