Study Using WST11 in Patients With Localized Prostate Cancer

Vascular-Targeted Photodynamic Therapy Using WST11 in Patients With Localized Prostate Cancer

The aim of this trial is to determine the optimal treatment conditions to achieve prostate cancer tumour ablation and to assess the effects of WST11-mediated Vascular-Targeted Photodynamic therapy (VTP) treatment in patients with localized prostate cancer.

The secondary objectives are to assess the safety and quality of life following WST11-mediated VTP treatment,to assess the effects,safety and quality of life following a second WST11-mediated VTP treatment; and to explore optimisation techniques to reduce the duration of the VTP procedure.

Study Overview

• Status: Completed
• Conditions: Prostate Cancer
• Intervention / Treatment: Drug: WST11; Drug: WST11

Detailed Description

This trial is designed as a multicentre, phase II, open-labeled, multi-arm, single intravenous (IV) dose study. The patient is to receive general anesthesia. WST11-mediated VTP will consist of the combination of a single IV administration of WST11 at doses of 4 or 6 mg/kg using 753nm laser light at a fixed power (150 mW/cm or 200 mW/cm or 250 mW/cm ) and light energy (200 J/cm or 300J/cm) delivered through transperineal interstitial optical fibers. The fibers are introduced into transparent needles that are positioned in the prostate under ultra sound guidance. The tumour location is established using transrectal biopsy and MR imaging. The number of fibers and the total light energy will be adapted to each patient based on a treatment planning proposed by treatment planning group.

Participation Criteria

Eligibility Criteria

• Ages Eligible for Study: 18 years and older (Adult, Older Adult)
• Accepts Healthy Volunteers: No
• Genders Eligible for Study: Male

Description

Inclusion Criteria:

• Men over 18 years of age;
• Diagnosed with prostate cancer and eligible for active surveillance;
• No prior treatment for prostate cancer;
• Prostate Cancer Stage up to cT2b - N0/Nx - M0/Mx (rT2c and pT2c are acceptable)
• Gleason score ≤ 3+3 For patients characterized with prostate mapping (transperineal template guided biopsy at 5mm intervals) a secondary pattern 4 is acceptable provided that it is not present in more than 3 cores from each side of the prostate and is no more than 3 mm cancer core length.
• PSA < 10 ng/mL;
• Signed Informed Consent Form.

Exclusion Criteria:

• Any condition or history of illness or surgery that, in the opinion of the investigator and/or the Sponsor, might confound the results of the study or pose additional risks to the patient.
• All patients whose current pre-operative cardiac evaluation does not show their fitness for a procedure requiring general anesthesia;
• Patients with a prior history of viral or alcoholic hepatitis, and other patients felt to be at risk for hepatotoxicity including concomitant use of potentially hepatotoxic medications or dietary supplements;
• Patients with a history of inflammatory bowel disease or other factors which may increase the risk of fistula formation;
• Men who have received any hormonal manipulation (excluding 5-alpha reductase inhibitors) or androgen supplements within the previous 6 months;
• Men previously treated by radiation therapy (external therapy or brachytherapy) or chemotherapy or any therapy for prostate cancer;
• Men who have received or are receiving chemotherapy for prostate carcinoma or other significant cancer;
• Men who have undergone previous TURP (trans-urethral resection of the prostate);
• Men who are currently receiving any medications having potential photosensitizing effects (e.g. tetracyclines, sulfonamides, phenothiazines, sulfonylurea hypoglycemic agents, thiazide diuretics and griseofulvin).
• Men who are receiving anticoagulant drugs (e.g.: coumadin, warfarin).
• Patient who stopped long term treatment of acetylsalicylic acid (aspirin) or other anti platelets agents less than 15 days before the procedure;
• Patient suspected of Disseminated Intravascular Coagulation (DIC) as defined by the presence of three out of the five following criteria: platelets <LLN, PT >ULN, aPTT >ULN, fibrinogen<LLN, D-Dimer >ULN
• History of non compliance with medical therapy and medical recommendations or an unwillingness or inability to complete patient self-administered questionnaires;
• Participation in a clinical study or receipt of an investigational treatment within the past 3 months;
• A history of porphyria;
• A history of sun hypersensitivity or photosensitive dermatitis;
• Renal disorders (blood creatinine > 1.5 x ULN) or known post mictional residue > 150cc
• Hepatic disorders (transaminases > ULN, bilirubin > ULN,). In case of slight abnormalities, another exam should be performed. If the results are within normal ranges, then the patient can be included;
• Hematological disorders (white cells < 2500/mm3, neutrophils < 1500/mm3, platelets < 140.000/mm3, Hb < 8 g/dL);
• Patient with contra-indication to MRI (such as pace maker, metal prosthesis, etc.).
