Low Risk Prostate Cancer

Brief summary

Multiple center, single-arm, open-label, 12-month follow-up phase IV pragmatic clinical trial in men with unilateral prostate cancer meeting eligibility criteria for the drug (as per the European Economic Area (EEA) Marketing Authorisation) to assess the occurrence and dynamics of the time with toxicities (urinary incontinence Grade 2 and over and/or erectile dysfunction Grade 2 and over) in patients 12 months following TOOKAD® VTP.

Detailed description

This is a multiple center, single-arm, open-label, 12-month follow-up phase IV pragmatic clinical trial. Men with unilateral prostate cancer meeting eligibility criteria for the drug (as per the EEA Marketing Authorisation) will receive TOOKAD® VTP under general anesthesia. The primary objective is to assess the occurrence and dynamics of the time with toxicities (urinary incontinence Grade 2 and over and/or erectile dysfunction Grade 2 and over) in patients 12 months following TOOKAD® VTP. Prior to the TOOKAD® VTP, patients will undergo routine ultrasound examination in the operating room for morphometric description of the prostate and to facilitate accurate treatment guidance for the treatment with TOOKAD® VTP. Treatment will then be applied to the prostate gland as a hemi-ablation procedure designed to destroy the lobe of the prostate gland that contains the cancer. Afterwards, patients will be followed for 12 months with clinical evaluation, data collection on erectile and urinary functions at 1, 2, 3 6 and 12 months, using the Expanded Prostate Cancer Index Composite (EPIC), International Index of Erectile Function (IIEF) and International Prostate Score Symptom (IPSS) questionnaires on Quality Of Life (QOL) and Prostate Specific Antigen (PSA) testing at 3, 6 and 12 months. The clinical follow-up of patients will follow local standard of care processes, based on recommendations in the European Summary of Product Characteristics (SmPC). This study is a phase IV pragmatic trial using optimal dose of TOOKAD® and optimal light-energy level conditions that were determined during development and approved by the European Commission.

Interventions

DRUGTOOKAD VTP

TOOKAD® VTP consists of the combination of a single, 10-minute IV infusion of TOOKAD® at the dose of 3.66 mg/kg, followed by the illumination of the zone to be treated with a 753-nm laser light delivered through transperineal interstitial optical fibers at a power of 150 mW/cm and light energy of 200 J/cm applied over 22 minutes and 15 seconds.

Cumulated time with toxicity (prevalence)12 monthsPrevalence at different points in time (either ED and/or UI) during the 12 months following VTP of ED with severity grade 2 or over and/or UI of severity grade 2 or over, as assessed using the EPIC instrument.
Cumulated time with toxicity (area under the curve)12 monthsArea under the curve with the presence of ED with severity grade 2 or over and/or UI of severity grade 2 or over, as assessed using the EPIC instrument
