Active clinical trials for "Prostatic Neoplasms"

RATIONALE: Zoledronate may prevent or decrease skeletal (bone)-related events (such as pain or fractures) caused by bone metastases and androgen deprivation therapy. It is not yet known whether treatment with zoledronate is effective in preventing bone-related events in patients who have prostate cancer and bone metastases. PURPOSE: This randomized phase III trial is studying how well zoledronate works in preventing bone-related events in patients who are receiving androgen deprivation therapy for prostate cancer and bone metastases.

RATIONALE: Biological therapies use different ways to stimulate the immune system and stop tumor cells from growing. Treating a person's T cells in the laboratory and then reinfusing them may cause a stronger immune response and kill more tumor cells. PURPOSE: Phase I trial to study the effectiveness of T-cell therapy in treating patients who have prostate cancer that has not responded to hormone therapy.

RATIONALE: A diet that is low in fat and/or high in flaxseed may slow or prevent disease progression of prostate cancer. PURPOSE: Randomized phase II trial to study the effectiveness of a diet that is low in fat and/or high in flaxseed in slowing or preventing disease progression in patients who have newly diagnosed prostate cancer.

This randomized phase II trial is studying ixabepilone to see how well it works compared to mitoxantrone and prednisone in treating patients with metastatic prostate cancer that has not responded to paclitaxel, docetaxel, or hormone therapy. Drugs used in chemotherapy work in different ways to stop tumor cells from dividing so they stop growing or die. Some tumors become resistant to chemotherapy drugs. Ixabepilone may reduce resistance to the drugs and allow the tumor cells to be killed. It is not yet known which chemotherapy regimen is more effective in treating metastatic prostate cancer

This is the first study of MLN2704 administered to humans. The purpose of the study is to determine the highest dose of MLN2704 that can be given safely to patients with prostate cancer, and to identify any side effects associated with taking the drug. This study will also evaluate how MLN2704 is taken up (absorbed), broken down (metabolized) and eliminated (excreted) by the body. This process is called pharmacokinetic analysis.

This study is being carried out to see if ZD4054 (Zibotentan) is effective in treating prostate cancer and spread of cancer to the bone, and if so, how it compares with placebo (sugar pill). The study will also provide further information on the safety of ZD4054 (Zibotentan).

RATIONALE: Androgens can cause the growth of prostate cancer cells. Drugs, such as triptorelin and flutamide, may stop the adrenal glands from making androgens. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving triptorelin and flutamide together with radiation therapy may be an effective treatment for prostate cancer. It is not yet known whether giving triptorelin and flutamide together with external-beam radiation therapy is more effective than external-beam radiation therapy alone in treating prostate cancer. PURPOSE: This randomized phase III trial is studying triptorelin, flutamide, and external-beam radiation therapy to see how well they work compared to external-beam radiation therapy alone in treating patients with stage II or stage III prostate cancer.

The rationale of the study was to evaluate different degarelix dosing regimens for a three-month interval that was to produce and maintain castration in prostate cancer patients through immediate and prolonged testosterone suppression, and to provide confirmatory evidence of the safety of degarelix.

The purpose of this study is to evaluate clinical and laboratory safety in patients receiving 4 different doses of GVAX® Prostate Cancer Vaccine in order to determine a maximum tolerated dose.

During 3D-conformal external beam radiation therapy treatments for prostate cancer, the prostate gland moves. The purpose of this study is to determine whether the placement of a prostate immobilization device into the rectum during radiation treatments will decrease the risk of rectal bleeding that is sometimes seen as a late effect from radiation.
