Safety and Efficacy Trial of a RNActive®-Derived Prostate Cancer Vaccine in Hormone Refractory Disease

Immunotherapy of prostate cancer is a promising approach for the treatment of advanced or recurrent forms of prostate cancer. Recently, immunotherapy of prostate cancer has been facilitated by the identification of a number of prostate specific antigens that are expressed in healthy and tumor prostate tissues. For prostatectomized patients, such antigens offer ideal targets for immunotherapy as they are only present in tumor but not in healthy tissue. The use of prostate specific antigens in a cancer vaccine is one attractive option for cancer immunotherapy.
