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 is 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.
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.

The aim of this study is to evaluate the safety of Vascular Targeted Photodynamic therapy with WST11 in patients with non-resectable or inoperable biliary carcinoma.
The aim of this study is to determine the dose of WST11 and light energy necessary to obtain desobstruction of the bronchial lumen using Vascular Targeted Photodynamic therapy in obstructi...
The purpose of this study is to test the safety of a combination of the study drug called WST11 and PDT. Photodynamic therapy (PDT) is a type of ablation therapy (treatment which destroys ...
The objectives of this study is to evaluate the safety(first objective) and efficacy(second objective)of an experimental drug product,Stakel®, in the treatment of neovascular AMD. The dr...
Management of localized prostate cancer is a major clinical challenge since most of these cancers won't evolve but a majority of patients will still undergo a life-changing radical surgery. Molecular ...
Radiotherapy can diminish quality of life (QoL) for prostate cancer patients. Our objective was to evaluate the effect of radiotherapy on QoL in men aged 75 years or older treated with radiotherapy fo...
The management of localized prostate cancer is challenging because of the many therapeutic options available, none of which is generally acknowledged as superior to the others in every respect. The se...
Active surveillance (AS) is increasingly used as a management strategy for localized prostate cancer. Coffee intake has been associated with lower prostate cancer incidence; and we assessed whether co...
There are multiple options for men diagnosed with localized prostate cancer. Patient decision aids (PtDAs) help empower individuals and reduce unwarranted practice variation, but few are used in clini...
A glycoprotein that is a kallikrein-like serine proteinase and an esterase, produced by epithelial cells of both normal and malignant prostate tissue. It is an important marker for the diagnosis of prostate cancer.
A synthetic retinoid that is used orally as a chemopreventive against prostate cancer and in women at risk of developing contralateral breast cancer. It is also effective as an antineoplastic agent.
Tissue ablation of the PROSTATE performed by ultrasound from a transducer placed in the RECTUM. The procedure is used to treat prostate cancer (PROSTATIC NEOPLASMS) and benign prostatic hypertrophy (PROSTATIC HYPERPLASIA).
Proteins secreted by the prostate gland. The major secretory proteins from the human prostate gland include PROSTATE-SPECIFIC ANTIGEN, prostate-specific acid phosphatase, prostate-specific membrane antigen, and prostate-specific protein-94.
The phosphoprotein encoded by the BRCA1 gene (GENE, BRCA1). In normal cells the BRCA1 protein is localized in the nucleus, whereas in the majority of breast cancer cell lines and in malignant pleural effusions from breast cancer patients, it is localized mainly in the cytoplasm.

Blood is a specialized bodily fluid that delivers necessary substances to the body's cells (in animals) – such as nutrients and oxygen – and transports waste products away from those same cells. In vertebrates, it is composed of blo...
