Active clinical trials for "Prostatic Neoplasms"

This study will look at the effects of a soy supplement called Revival on memory, quality of life, and hot flashes in men with prostate cancer who are being treated with testosterone suppression therapy. Hypothesis: Treating men who have prostate CA with daily Revival will result in at least a 50% reduction in hot flashes compared to placebo.

Docetaxel-based therapy has been shown to prolong survival as first-line therapy for patients with hormone refractory prostate cancer (HRPC), and has become the standard of care. The beneficial effects of any therapy in HRPC may be diverse and include reduction in tumor bulk (when measurable), reduction in prostate-specific antigen PSA, reduction in symptoms (particularly pain), or stabilization of disease. Clear reductions in tumor bulk or PSA may provide objective evidence of a treatment effect, and stabilization of disease may be just as clinically meaningful in patients who are actively progressing prior to starting therapy. Pemetrexed has shown a broad array of activity in many diseases that until now were thought to be non-responsive to chemotherapy in the second-line setting. This trial is designed to further assess the efficacy, safety, tolerability, and pharmacogenetics of pemetrexed as a single agent in subjects with HRPC whose disease has progressed following one prior taxane-based chemotherapy regimen for HRPC.

Because of the high incidence of post-radiation erectile dysfunction (ED), up to 72% after external-beam radiotherapy, this patient category represents a most difficult therapeutic challenge. Therefore, prevention of ED could be more effective than treatment. Tadalafil, a new phosphodiesterase type 5 inhibitor, has been recently introduced. No studies have investigated the efficacy of tadalafil in preventing ED in patients undergoing radiotherapy for prostate cancer. Efficacy of tadalafil can last up to 36 hours after intake. This will result in a prolonged and continuos enhancement of penile vascular responsiveness. This randomized, double-blind, placebo-controlled study has been designed to evaluate the efficacy of 20-mg of tadalafil administered for 12 months in maintaining erectile function of potent patients undergoing external-beam radiotherapy for prostate cancer.

This pilot study is designed to determine the feasibility and safety of administering docetaxel at various dosing levels on a bi-weekly schedule in older men with hormone refractory prostate cancer.

This study will evaluate the safety, tolerability and efficacy of zoledronic acid administered intravenously every 3-4 weeks in patients with bone metastases from either breast cancer or prostate cancer.

To evaluate the efficacy and safety of Trovax and GM-CSF in patients with prostate cancer.

The purpose of this study is to assess the anti-tumor activities and safety of abiraterone acetate in participants with prostate cancer (a disease in which cells in the prostate gland [a gland in the male reproductive system found below the bladder and in front of the rectum] become abnormal and start to grow uncontrollably, forming tumors) who have failed taxane (docetaxel)-based chemotherapy.

Dutasteride inhibits the conversion of testosterone to dihydrotestosterone (DHT) the male hormone that leads to benign prostate growth. By blocking the conversion of testosterone to DHT, dutasteride could allow bicalutamide to be a more effective anti-androgen thus prolonging bicalutamide's efficacy.

For patients who have one or two metastases in the brain, the tumor(s) can often be removed with surgery to relieve symptoms from the tumor(s) and to improve survival. However, about half of all patients who have the tumor(s) removed with surgery will develop regrowth (recurrence) of the tumor. To prevent this regrowth of tumor, some patients receive radiation to the entire brain (whole brain radiation) after surgery. This involves daily treatment for about two to three weeks, and may cause long-term neurological problems, such as memory loss. Stereotactic radiosurgery (SRS) is sometimes used instead of surgery to treat brain metastasis. This involves the use of a special head frame and sophisticated computer programs that enable us to deliver a high dose of radiation to a small focused area of the brain in only one treatment. Research has shown that the results of treatment with SRS are as good as surgical removal of the tumor. SRS and surgical resection are considered the standard options for the treatment of brain metastases. This Phase II clinical trial is studying the combination of these two techniques. The purpose of this study is to evaluate the use of SRS following surgical removal of brain metastases. The outcomes we will be looking at are tumor regrowth after treatment and side effects of treatment.

ARI109924 will be a 2-year, multicentre, randomised, double-blind, placebo-controlled trial assessing the efficacy and safety of dutasteride in extending time to prostate specific antigen (PSA) doubling in men who have been treated for clinically localised prostate cancer (PCa) with a radical therapy (radical prostatectomy, primary radiotherapy or salvage radiotherapy) with curative intent but who experience a biochemical failure (PSA rise) afterwards without signs or symptoms of metastases.
