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

Completed · Phase 1

Conditions studied: Prostatic Neoplasms

In brief

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).

Who can join

Age: 18 and older. Sex: male. Healthy volunteers: not accepted.

You may qualify if…

• Histologic proof of prostatic adenocarcinoma without evidence of regional and/or distant metastasis, clinical stage T1c, T2 or T3 with high grade disease (Gleason's 7 - 10) on initial biopsy, or PSA greater than 10 ng/ml with any stage or Gleason score.
• Recent (equal to or less than 1 month prior to study entry) negative bone scan and CT scan of abdomen/pelvis.
• Life expectancy of at least 10 years.
• Appropriate surgical candidate for radical prostatectomy and a performance status of equal to or less than 2 (Zubrod scale).
• Patients should have adequate bone marrow function defined as an absolute peripheral granulocyte count equal to or greater than 1,500 and platelet count of equal to or greater than 100,000, adequate hepatic function with a bilirubin equal to or less than 1.5 mg per cent and SGPT less than 2 x the upper limits of normal, adequate renal function defined as serum creatinine equal to or less than 2.0 mg per cent.
• Patients must have normal coagulation profile (PT, PTT) and no history of substantial non-iatrogenic bleeding diatheses. Use of anticoagulants is limited to local use only (for control of central line patency).
• Patients must sign an informed consent indicating that they are aware of the investigational nature of the study, in keeping with the policies of the institution.

You may not qualify if…

• Previous or current hormonal treatment, chemotherapy, radiation therapy, immunotherapy or other investigational status drug within the past 4 weeks.
• Unable to tolerate transrectal ultrasound.
• Patients who are not appropriate surgical candidates for radical prostatectomy based on the evaluation of co-existent medical diseases and competing causes of death.
• Patients with uncontrolled cardiac, hepatic, renal or neurologic/psychiatric disorders are not eligible.
• Patients who are HIV positive or have chronic hepatitis B or C infections are not eligible (because of possible immune effects of these conditions).
• Patients with a history of primary or secondary immunodeficiency or patients taking immunosuppressive drugs such as corticosteroids continuously for greater than 4 months [greater than 5 mg hydrocortisone/day] are ineligible. (The experimental treatment being evaluated in this protocol depends on an intact immune system. Patients who have a decreased immune competence may be less responsive to the experimental treatment and more susceptible to its toxicities.)
