Active clinical trials for "Prostatic Neoplasms"

Fatigue is one of the most common symptoms of prostate cancer. Fatigue is a lack of energy that makes it harder to do the things you normally do every day. Some symptoms of fatigue are: feeling tired and/or weak; having less interest in activities; having trouble concentrating; feeling "down"; feeling exhausted for no clear reason. There are not many drugs that are helpful in treating fatigue. However, one group of medications does seem to be useful. In this study, we, the investigators at Memorial Sloan-Kettering Cancer Center, will be using a psychostimulant called Ritalin. The aim of this study is to see if this drug is helpful in treating fatigue in prostate cancer. We are also studying the side effects of this medication.

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.

Phase II trial to study the effectiveness of APC8015 combined with bevacizumab in treating patients who have undergone radiation therapy and/or surgery and who have progressive prostate cancer. Biological therapies such as APC8015 use different ways to stimulate the immune system and stop cancer cells from growing. Monoclonal antibodies such as bevacizumab can locate tumor cells and kill them without harming normal cells. Combining monoclonal antibody therapy with biological therapy may kill more cancer cells.

Patients with bone metastases or bone lesions caused by breast cancer, multiple myeloma or prostate cancer will be treated with IV Zometa in a 15 minute infusion. Pain will be evaluated, as well as time in chair, quality of life and safety of Zometa.

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: SU5416 may stop the growth of prostate cancer by stopping blood flow to the tumor. Dexamethasone may be effective in slowing the growth of prostate cancer cells. It is not yet known whether SU5416 or dexamethasone is more effective in treating progressive prostate cancer. PURPOSE: Randomized phase II trial to compare the effectiveness of SU5416 with that of dexamethasone in treating patients who have progressive prostate cancer that has not responded to hormone therapy.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining more than one chemotherapy drug may kill more cancer cells. PURPOSE: Phase II trial to study the effectiveness of phenylbutyrate plus azacitidine in treating patients who have acute myeloid leukemia, myelodysplasia, non-Hodgkin's lymphoma, multiple myeloma, non-small cell lung cancer, or prostate cancer.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: Phase II trial to study the effectiveness of R115777 in treating patients who have progressive, metastatic prostate cancer that has not responded to hormone therapy.

RATIONALE: Vaccines may make the body build an immune response to kill tumor cells. PURPOSE: Phase I trial to study the effectiveness of vaccine therapy given with QS21 in treating patients who have progressive prostate cancer.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. PURPOSE: Phase I trial to study the effectiveness of doxorubicin plus estramustine in treating patients with metastatic recurrent prostate cancer that does not respond to hormone therapy.
