Patients were stratified by whether they had no measurable disease [NMD] at the time of treatment (usually because of surgical resection of metastases), or whether they had objectively measurable disease (OMD) by physical examination or radiologic scans per response evaluation criteria in solid tumors (RECIST criteria). Key endpoints were the results of delayed type hypersensitivity (DTH) skin testing to their own irradiated tumor cells, event-free survival [death or disease progression], overall survival, and objective tumor regression in patients who have measurable disease at the time vaccine therapy was initiated. This study was activated in the fall of 2000, and closed to accrual in June 2007.
