Phase I - Pre-Radical Prostatectomy RTVP-1 Gene Therapy for Prostate Cancer

Summary

The purpose of this study is to conduct a Phase I clinical trial involving in situ RTVP-1 gene therapy for prostate cancer. We will conduct necessary safety evaluations on a new adenovirus that contains the human genes for RTVP-1. This virus will then be evaluated for safety in men with prostate cancer prior to radical prostatectomy. Based on the preclinical data, we hope that this treatment will induce not only a local cytotoxic and antiangiogenic effect but also, a systemic antitumor immune response capable of eradicating micrometastatic disease (the reason for recurrence in many of these patients).
