Filter by:This study will examine whether the new investigational drug EPO906, given by intravenous infusion (IV directly into the vein), is effective in shrinking tumors and preventing the growth of cells that cause prostate cancer.
RATIONALE: Specialized radiation therapy that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. It is not yet known which dose of radiation therapy is more effective in treating stage II prostate cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of two different doses of specialized radiation therapy in treating patients who have stage II prostate cancer.
This study will determine the maximum dose of docetaxel that can be given safely in combination with ketoconazole for treating advanced prostate cancer. Docetaxel is approved for the treatment of several other types of cancers; ketoconazole is an approved antifungal medication that is also commonly used in high doses to treat prostate cancer. Patients 18 years of age and older with advanced prostate cancer that does not respond to hormone therapy may be eligible for this study. Candidates will be screened with blood tests to evaluate liver, kidney and other organ function and with x-rays, scans, or other imaging tests to determine the extent of disease. Participants will take the following medications: - Docetaxel daily, infused through a vein over 30 minutes, in 4-week cycles-3 consecutive weeks of drug followed by one week of rest - Dexamethasone, 12 hours and 1 hour before and 12 hours after docetaxel infusions to help prevent fluid retention caused by the docetaxel - Ketoconazole, 3 times a day - Hydrocortisone, twice a day to replace a loss of natural steroids caused by the ketoconazole Patients will be hospitalized 1 to 2 days each for the first and second doses of docetaxel to allow for frequent blood draws to measure blood levels of the drug. Ketoconazole will be started about 2 weeks after the first dose of docetaxel and the second dose of docetaxel will be given 2 days after that. In order to determine the maximum tolerated dose of docetaxel, the first few patients in the study will be given a low dose of the drug, and subsequent patients will get increasingly higher doses until unacceptable side effects occur. Because prostate cancer cells may grow if exposed to testosterone, patients may have to have their testosterone production suppressed either surgically (removal of the testicles) or medically with an injection of leuprolide or goserelin, which are luteinizing hormone-release hormone agonists that reduce the amount of testosterone. Imaging studies, such as x-rays, bone scans or computed tomography (CT) scans, will be done about every 3 months to examine how the tumor is responding to therapy. After six treatment cycles, patients will have monthly chest x-rays to check for fluid around the lining of the lungs, which may occur as a result of docetaxel therapy. Treatment is expected to continue for at least 3 to 6 months, although this time could be shortened or extended depending on the tumor response to therapy or side effects of the drugs. Patients who do not experience bad side effects and whose tumor does not grow during the first 3 treatment cycles will continue treatment; those who experience unacceptable side effects will be taken off the study. ...
RATIONALE: Imaging procedures such as magnetic resonance imaging (MRI) and magnetic resonance spectroscopic imaging (MRSI) may improve the ability to detect the extent of prostate cancer. It is not yet known if MRI combined with MRSI is more effective than MRI alone in detecting the extent of prostate cancer. PURPOSE: Diagnostic trial to compare the effectiveness of combining MRI with MRSI to that of MRI alone in determining the extent of prostate cancer in patients who are scheduled to undergo surgery to remove the prostate gland.
RATIONALE: Androgens can stimulate the growth of prostate cancer cells. Drugs such as goserelin, leuprolide, flutamide, or bicalutamide may stop the adrenal glands from producing androgens. Internal radiation uses radioactive material placed directly into or near a tumor to kill tumor cells. Combining hormone therapy with internal radiation may be effective in treating locally recurrent prostate cancer. PURPOSE: Phase II trial to study the effectiveness of hormone therapy followed by internal radiation in treating patients who have locally recurrent prostate cancer following external-beam radiation therapy.
RATIONALE: Androgens can stimulate the growth of prostate cancer cells. Hormone therapy using exemestane plus bicalutamide may fight prostate cancer by reducing the production of androgens. It is not yet known if exemestane is more effective with or without bicalutamide in treating prostate cancer. PURPOSE: Randomized phase II trial to study the effectiveness of exemestane with or without bicalutamide in treating patients who have stage IV prostate cancer that has been previously treated with hormone therapy or surgery.
RATIONALE: Soy protein supplement may prevent or delay the development of prostate cancer in patients who have elevated prostate-specific antigen (PSA) levels. PURPOSE: Randomized phase II trial to determine the effectiveness of soy protein supplement in preventing prostate cancer in patients who have elevated PSA levels.
This phase I trial is studying the side effects and best dose of giving 7-hydroxystaurosporine together with irinotecan hydrochloride in treating patients with metastatic or unresectable solid tumors, including triple-negative breast cancer (currently enrolling only patients with triple-negative breast cancer since 6/8/2007). Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Giving 7-hydroxystaurosporine together with irinotecan hydrochloride may help kill more cancer cells by making tumor cells more sensitive to the drug.
SGN-15 is being investigated for therapy of patients with prostate cancer in combination with the cytotoxic agent, Taxotere. The study is an open label, randomized phase II study for patients with documented hormone refractory prostate cancer who have not had any prior therapy with Taxotere or Novantrone. Both SGN-15 and Taxotere will be administered weekly over two 6 week courses separated by a 2 week rest period.
RATIONALE: Chemoprevention therapy is the use of certain drugs to try to prevent the development of cancer. The use of selenium may be an effective way to prevent prostate cancer in patients who have neoplasia of the prostate. PURPOSE: Randomized phase III trial to study the effectiveness of selenium in preventing prostate cancer in patients who have neoplasia of the prostate.
