|Prostate Cancer||Drug: WST 11 -mediated -VTP||Phase 1 Phase 2|
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

Experimental: WST11 (TOOKAD® Soluble)
WST11-mediated-VTP The WST11-mediated VTP procedure will consist of a single, 10 min, IV administration of WST11 at doses of either 2mg/kg, 4 mg/kg or 6 mg/kg, followed by light activation delivered through one or more transperineal interstitial optical fibers using 753 nm laser light at escalating fixed energy doses
Drug: WST 11 -mediated -VTP
The WST11-mediated VTP procedure will consist of a single, 10 min, IV administration of WST11 at doses of either 2mg/kg, 4 mg/kg or 6 mg/kg, followed by light activation delivered through one or more transperineal interstitial optical fibers for 20 minutes using 753 nm laser light at escalating fixed energy doses of 200 J/cm and 300 J/cm, by escalating power at each energy to 167 mW/cm and 250 mW/cm, respectively. A brachytherapy-like template is used for the placement of the optical fiber(s) that are positioned in the prostate areas of interest under trans-rectal ultrasound image guidance.
Other Name: TOOKAD Soluble
- Prostate Biopsy [ Time Frame: Month 6 ]
WST 11(TOOKAD® Soluble) Arm/Group Description To define the study drug and light dosage combination to achieve negative biopsy in the treated lobe
- Prostate Biopsies [ Time Frame: Month-6 ]Number of patients who had a negative biopsy at Month-6
- Pharmacokinetic Parameters-Cmax [ Time Frame: T0, 5 min,10 min, 4 h, 8 h, post dose ]For each dose group, several pharmacokinetics parameters have been calculated.
- Percentage of Prostatic Necrosis at Day 7 as Observed on the 7-Day MRI [ Time Frame: Day 7 ]
The adjusted prostate necrosis percentage was defined as follows:
The Day 7 necrosis percentage is the proportion, expressed in %, of Day 7 prostate necrosis volume by planimetry in the treated lobe compared with half the prostate volume by planimetry, considering the average between the baseline volume and Day 7 volume;
- International Index of Erectile Functions (IIEF) Results [ Time Frame: Month 1-Month 3- Month 6- Month 12 ]The International Index of Erectile Functions questionnaire is 15 questions patients auto questionnaire. The results presented are those of the erectile function domain which comprise 6 questions. Possible scores range is 1 to 30 . Best score is 30, worst score is 1.
- International Prostate Symptom Score (IPSS) Results [ Time Frame: Month 1, Month 3 , Month 6 , Month 12 ]The International Prostate Symptom Score (IPSS) is a 7 questions patients auto-questionnaire about urinary symptoms. the possible scores range are 0 to 35 . Best score is 0 worst score is 35
- Pharmacokinetic Parameters-Tmax [ Time Frame: T0, 5 min,10 min, 4 h, 8 h, post dose ]For each dose group, several pharmacokinetics parameters have been calculated.
- Pharmacokinetic Parameters -T1/2 [ Time Frame: T0, 5 min,10 min, 4 h, 8 h, post dose ]For each dose group, several pharmacokinetics parameters have been calculated.
