Brief Title: Safety and Tolerability Study Using WST11 In Patients With Localized Prostate Cancer
Official Title: A Prospective, Multicenter Phase I/II Safety and Tolerability Study of Unilateral Vascular-Targeted Photodynamic Therapy Using WST11 in Patients With Localized Prostate Cancer
Study ID: NCT00946881
Brief Summary: The aim of this study is to determine the optimal treatment conditions (WST11 dose and light energy dose) to achieve ablation in one lobe of the prostate and to evaluate the safety and quality of life of WST11 medicated Vascular-Targeted Photodynamic therapy (VTP) in men with localized prostate cancer.
Detailed Description: This study is designed as a multicenter, phase I/II, prospective, open-labeled, single intravenous (IV) dose, clinical trial in patients with localized prostate cancer. The study population will be men who have been offered curative therapy (radical prostatectomy; cryotherapy; brachytherapy; External Beam RadioTherapy (EBRT), and refused. Patients must have already had a previous biopsy showing a histologically proven carcinoma of the prostate. The identification and the location of the tumor will be done using both dynamic contrast Magnetic resonance Imaging (MRI) and biopsy. Only unilateral treatment with WST11-medicated VTP will be performed during the study. Treatment will consist of a single, 10 minute, IV administration of WST11 at doses of 2mg/kg, 4 mg/kg or 6 mg/kg, followed by either light activation delivered through transperineal interstitial optical fibers for 20 minutes using 753 nm laser light at escalating fixed energy doses of 200 J/cm or 300 J/cm by escalating power at each energy to 167 mW/cm or 250 mW/cm respectively. A brachytherapy-like template is used for the placement of the transparent implant catheters which are positioned in the prostate under transrectal ultrasound image guidance. The illumination fiber(s) are then inserted into the implant catheters. If the safety profile for a given WST11 and light dose is acceptable, additional patients may be treated with multiple fibers at that WST11 treatment dose. For cases where the Month 6 biopsy is positive, the patient will be offered the opportunity to be retreated with WST11
