Filter by:Prostate cancer is the second leading cause of mortality in men, representing 10 deaths about of 100 cancers (INVS 2009). Treatment for metastatic prostate cancer, when becoming resistant to hormone-treatment, is mostly resumed to a relatively ineffective chemotherapy (Docetaxel/TAXOTERE®) (1). Recently, numerous clinical and preclinical works showed that Metformin could represent an excellent candidate for treatment of advanced prostate cancer. This is a widely prescribed drug, for type 2 diabetes, with clinical advantage of exhibiting very rare serious side effects. On the other hand, the use of this molecule in patients was associated with a decrease of tumors incidence, in particular prostate cancer (2). Numerous in vitro and in vivo studies support its role as an anti-cancer drug, in several cell lines (3). These experimental results are consistent with a clinical trial pilot study, performed in colorectal cancer, showing anti proliferative effect of Metformin (4). In the field of prostate, F. Bost in J.F. Tanti's team (INSERM U895, Nice) demonstrated that Metformin inhibits cell viability of human prostate cancer cells, via mTOR downregulation and decrease tumor growth in a xenograft model (5). Furthermore, preclinical data performed by this team showed that Metformin increased significantly apoptosis induced by TAXOTERE®. Therefore, by targeting specifically cancer cell metabolism, Metformin offers new promising therapeutic strategy. The primary objective of this randomized study is to evaluate the biological efficacy of Metformin combination with TAXOTERE® in patients with metastatic hormone-refractory prostate cancer. To achieve this purpose, PSA response rate will be evaluated according to ASTRO definitions (Bubley, Carducci et al. 1999). Concurrently, secondary endpoints will be under investigation in order to evaluate the clinical response according to RECIST criteria, the overall and free-progression survival and the quality of life. Toxicity assessment will also be performed regarding to this drug combination. Considering the well tolerability of Metformin and the first clinical and pre-clinical data reports of it use in cancer treatment, combining Docetaxel (TAXOTERE®) with Metformin may represent a promising strategy for treatment of hormone-refractory prostate cancer.
The purpose of this study is to investigate the safety and efficacy of abiraterone in participants with metastatic castration-resistant prostate cancer (mCRPC) who have received docetaxel-based chemotherapy (treatment of disease, usually cancer, by chemical agents).
The purpose of this study is to allow continued use of pasireotide in patients who are on pasireotide treatment in a Novartis-sponsored study and are benefiting from the treatment as judged by the investigator.
Tremodi is an observational, non-interventional, prospective, open-label, non-comparative study that will collect real life data of a treatment with Depo-Eligard® in 3 different administrations in male prostate cancer patients. Once the examining physician has decided on the therapeutic approach and if the selection criteria are fulfilled, he will propose the patient to participate in the study. An informed consent form will be collected for all participants in the study. There are 2 possible study visits that coincide with a routine consultation, namely visit 1 (inclusion visit) and visit 2 (end of study visit). On both visits, Adverse Drug Reactions (adverse event caused by Depo-Eligard®) are collected and the patient will be asked to complete a Quality Of Life questionnaire (EORTC QLQ-C30). At visit 2, the examining physician will give a global evaluation of the treatment with Depo-Eligard® and assesses the treatment benefit of the patient. Testosterone and Prostate Specific Antigen (PSA) blood values are collected during both visits, if available.
This is a Phase Ib, open label study of ARN-509 administered in combination with abiraterone acetate and prednisone in patients with metastatic castration-resistant prostate cancer.
This phase II trial studies how well magnetic resonance (MR)-guided laser interstitial thermal therapy works in treating patients with prostate cancer. Laser therapy uses intense, narrow beams of light to cut and destroy tissue and may help treat prostate cancer
Up to 16 patients with confirmed low- or intermediate risk prostate cancer scheduled for a radical prostatectomy will be asked to have the Irreversible Electroporation (IRE) procedure approximately 30 days prior to the prostatectomy. Ablation with IRE will be performed using similar planning criteria, procedure protocol, instruments and software used for brachytherapy, a conventional targeted radiation therapy where radioactive seeds are implanted into prostate tumours. Patients will have an ultrasound of the prostate and the imaging data will be entered into the Planning Software system. The volume of the prostate is measured and a specified ablation zone will be determined. The IRE will be performed under general anaesthetic and the specified zone identified in the planning stage will be ablated. Four IRE electrode needles will be placed into the prostate under ultrasound image guidance. When the needles are in place, electric pulses of one to two minutes duration are used to ablate the specified zone. The total procedure time will be approximately 1 hour. Safety data will be collected and patients will be followed up at 1 week, 2 weeks post IRE, pre- prostatectomy, post prostatectomy and 1 week post prostatectomy. The safety data collection is at 2 weeks post IRE. Before the IRE procedure, patients will have a Magnetic Resonance Imaging (MRI) and Contrast Enhanced Ultrasound (CEUS) of the prostate. The patients will have their scheduled prostatectomy at approximately 30 days after the IRE procedure. Pre-prostatectomy, the ablation zone will be radiologically assessed by a control MRI/CEUS. Post prostatectomy, efficacy of ablation will be determined by histological examination of the prostate by the Pathology Department and measured as complete or incomplete ablation. The primary outcome is safety as measured by the composite of procedural device and post procedural adverse events, measured with the Common Terminology Criteria for Adverse Events v 4 (CTCAE), Expanded Prostate Cancer Index Composite (EPIC) score, International Prostate Symptom Score (IPSS) or required catheterization time and International Index of Erectile Function (IIEF) and efficacy of ablation determined by histological examination post prostatectomy. Secondary outcomes will be patients procedure satisfaction measured by patient satisfaction questionnaire, post procedural pain management and Visual Analogue Scale (VAS) pain score, time to ambulation, length of hospital stay.
The proposed clinical trial will study the effects of 12 months of therapy with ARN-509 alone, or in combination with an LHRH agonist (LHRHa), each compared with LHRHa alone, in men with a rapidly rising serum PSA after prior definitive local therapy for prostate cancer. The endpoints selected reflect measurable short term effects of androgen deprivation therapy (ADT), including quality of life and several metabolic parameters. In addition, the relative effect of each treatment strategy on PSA suppression as well as testosterone recovery (and subsequent PSA progression) after 12 months of therapy will be evaluated.
This phase II trial studies how well itraconazole works in treating patients with biochemically relapsed prostate cancer. Itraconazole may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
