A Phase 3 Efficacy Study of a Recombinant Vaccinia Virus Vaccine to Treat Metastatic Prostate Cancer

Status: Recruiting
Phase: Phase 3
Diagnosis: Prostate Cancer
NCT ID: NCT01322490 (View complete trial on ClinicalTrials.gov)
DFCI Protocol ID: 11-398


The purpose of this study is to determine whether PROSTVAC alone or in combination with GM-CSF is effective in prolonging overall survival in men with few or no symptoms from metastatic, castrate-resistant prostate cancer.
