Active clinical trials for "Prostatic Neoplasms"

This is a Phase II study of docetaxel, bevacizumab, prednisone and thalidomide in patients with androgen independent metastatic prostate cancer who are previously untreated with chemotherapy. The primary objective of this study is to determine if the combination of docetaxel, thalidomide and bevacizumab is able to be associated with a sufficiently high proportion of patients with a prostate-specific antigen (PSA) response to be worthy of further investigation in metastatic prostate cancer. We will also be looking at multiple secondary endpoints. These will include possible pharmacokinetic interactions among the study agents, potential correlation between patient genotype and efficacy of treatment. We will also be looking for circulating tumor cells in blood before and after treatment. Additionally we will be monitoring the tolerability of the regimen and survival duration as endpoints as well. We hope to use this trial to build on the promising results seen in our thalidomide/docetaxel protocol where there was a significant PSA decline and a trend toward survival benefit.

BAY 43-9006 (Sorafenib) is an experimental cancer drug produced by Bayer Health Care Corporation. It represents a new class of anticancer agents known as bi-aryl ureas. This study will investigate its effect on prostate cancer and its side effects. Researchers expect to enroll a maximum of 46 men with prostate cancer for this study. The duration of the study will depend on its results. Before beginning to take the drug, patients will be admitted to the hospital for 2 days, have a medical examination and give blood samples, and have a tumor or bone marrow biopsy. On the first day of the study, patients will begin taking the drug as 2 tablets twice daily, morning and evening. Blood will be taken throughout the day to determine the drug's level in the bloodstream. Patients will be discharged from the hospital on the second day, and will continue to take the drug twice daily until instructed to stop. During each of the first 4 weeks, patients will be required to have their blood pressure checked. At the end of the first 4 weeks, patients will have a physical examination and blood tests, as well as a second tumor or bone marrow biopsy. After the first 4 weeks, patients will continue with their drug regimen. At the end of each 4-week cycle, patients will have a physical examination and blood tests. Patients will also have x-Rays, computed tomography (CT) scans, and/or magnetic resonance imaging (MRIs) at every other 4-week examination or as required. Patients will be asked to keep a diary recording the time and amount of their medication for this study.

RATIONALE: Drugs used in chemotherapy, such as docetaxel, work in different ways to stop tumor cells from dividing so they stop growing or die. Erlotinib may stop the growth of tumor cells by blocking the enzymes necessary for their growth. Combining docetaxel with erlotinib may kill more tumor cells. PURPOSE: This phase II trial is studying how well giving docetaxel together with erlotinib works in treating older patients with progressive prostate cancer that has not responded to hormone therapy.

RATIONALE: GTI-2040 may stop the growth of tumor cells by blocking the enzymes necessary for their growth. Drugs used in chemotherapy, such as docetaxel, work in different ways to stop tumor cells from dividing so they stop growing or die. GTI-2040 may help docetaxel kill more tumor cells by making them more sensitive to the drug. PURPOSE: This phase II trial is studying how well giving GTI-2040 together with docetaxel and prednisone works in treating patients with prostate cancer that has not responded to hormone therapy.

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

RATIONALE: Androgens can stimulate the growth of prostate cancer cells. Drugs such as nilutamide, bicalutamide, flutamide, or cyproterone may stop the adrenal glands from producing androgens. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. It is not yet known whether hormone therapy is more effective with or without chemotherapy in treating prostate cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of hormone therapy with or without docetaxel and estramustine in treating patients who have prostate cancer that is locally advanced or at high risk of relapse.

This study is for patients with cancer of the prostate gland that has metastasized or spread outside the prostate to other parts of the body. Patients have already been treated with a drug called docetaxel or Taxotere® (with or without the addition of a steroid called prednisone) some time in the recent past. They either did not respond to this therapy or responded to this therapy, but now the cancer is progressing (growing larger or has spread to other areas of the body). Custirsen (OGX-011) is an experimental drug that has been shown to increase the effectiveness of chemotherapy in several kinds of tumors, including prostate cancer. Both docetaxel and mitoxantrone have anticancer activity in prostate and are approved by Health Canada and the Food and Drug Administration for the treatment of patients with prostate cancer.

This randomized phase III trial is studying docetaxel, prednisone, and bevacizumab to see how well they work compared to docetaxel and prednisone in treating patients with prostate cancer that did not respond to hormone therapy. Drugs used in chemotherapy, such as docetaxel and prednisone, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Bevacizumab may also stop the growth of tumor cells by blocking blood flow to the tumor. It is not yet known whether docetaxel, prednisone, and bevacizumab are more effective than docetaxel and prednisone in treating prostate cancer.

RATIONALE: A low-fat, high-fiber diet that includes soy protein may prevent disease progression in patients with hormone-refractory prostate cancer. Nutrition counseling may help motivate patients to follow this diet. PURPOSE: Randomized phase I trial to study the effectiveness of behavior-based dietary interventions, such as receiving nutrition counseling, in helping patients who have hormone-refractory prostate cancer follow a low-fat, high-fiber, soy-supplemented diet.

RATIONALE: Drugs used in chemotherapy, such as fenretinide, work in different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: This phase II trial is studying how well fenretinide works in treating patients with advanced or metastatic hormone-refractory prostate cancer.
