Filter by:This randomized study is looking at the benefits of using docetaxel (chemotherapy) added to one of the standard treatments (radiation and hormones) for men with high-risk prostate cancer.
The aim of the study is to determine the optimal dose of the combination of docetaxel and gemcitabine in patients with hormone refractory prostate cancer, and evaluate this dose with respect to efficacy and toxicity in a phase II trial.
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.
This study will evaluate the side effects of a fixed dose of vaccine and GM-CSF with increasing doses of anti-CTLA-4 antibody in patients with advanced prostate cancer. The vaccine consists of a "priming vaccine" called PROSTVAC/TRICOM, made from vaccinia virus, and a "boosting vaccine" called PROSTVAC-F/TRICOM, made from fowlpox virus. GM-CSF is a chemical that boosts the immune system, and anti-CTLA-4 antibody is a protein that may improve anti-tumor activity and the response to the vaccines. DNA is inserted into the priming and boosting vaccine viruses to cause production of proteins that enhance immune activity and also to produce prostate specific antigen (PSA)-a protein that is normally produced by the patient's tumor cells. Patients 18 years of age and older with androgen-insensitive prostate cancer that has spread beyond the original site may be eligible for this 7-month study. Candidates must have disease that has worsened despite treatments with hormones and up to one chemotherapy regimen. Their tumor must produce PSA, and they must have no history of allergy to eggs or egg products Candidates are screened with a medical history and physical examination, blood and urine tests, electrocardiogram, pathological confirmation of the diagnosis and presence of the PSA marker, chest x-rays, imaging studies to assess the extent of tumor, and, if clinically indicated, a cardiologic evaluation. Participants receive the priming vaccination on study day 1. After 2 weeks and then again every 4 weeks while on the study, they receive a boosting vaccine. All vaccines are injected under the skin. On the day of each vaccination and daily for the next 3 days, patients receive an injection of GM-CSF to increase the number of immune cells at the vaccination site. On the day of the first six boosting vaccinations, they receive anti-CTLA-4 antibody as an infusion through a vein over 90 minutes. Patients are monitored for safety and treatment response with the following tests and procedures: - Blood and urine tests monthly, or more often if needed, to monitor liver, kidney, and other organ function. - Imaging studies to assess the tumor before starting treatment, again around study days 99 and 183, and then every 3 months after that while on study. - Apheresis (a procedure for collecting immune cells called lymphocytes) to measure the immune response to treatment. Apheresis is done three times: before starting the study and again around study days 99 and 183. For this procedure, blood is collected through a needle in an arm vein. The blood circulates through a machine that separates it into its components by spinning, and the lymphocytes are extracted. The rest of the blood is returned to the patient through the same needle. This will only be done in participants who have the tissue marker HLA-A2 (about 50% of patients). Patients whose disease responds to treatment and who do not develop severe side effects may continue treatment beyond the initial 7-month study period on vaccine alone (without the antibody). After treatment is completed, patients are monitored for up to 15 years. This includes a medical history and physical examination for 5 years following the last vaccination. Information beyond 5 years is collected once a year by telephone.
The purpose of this trial is to confirm a safe dose of AS1404, to be given with docetaxel, and to see whether adding AS1404 and docetaxel together improves the outcome of the treatment, when compared to docetaxel alone.
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.
The purpose of this study is to assess the antitumor activity of weekly ridaforolimus study treatment in participants with taxane-resistant AIPC.
This phase II trial is studying how well vaccine therapy works in treating patients with recurrent prostate cancer. Vaccines made from peptides may help the body build an effective immune response to kill tumor cells
Vaccines made from a gene-modified virus may help the body build an effective immune response to kill tumor cells. Biological therapies, such as GM-CSF, may stimulate the immune system in different ways and stop tumor cells from growing. Androgens can cause the growth of prostate cancer cells. Drugs, such as bicalutamide and goserelin, may stop the adrenal glands from making androgens in patients whose tumor cells continue to grow. Giving vaccine therapy together with GM-CSF and, when needed, androgen ablation may be a more effective treatment for prostate cancer. This phase II trial is studying how well giving vaccine therapy together with GM-CSF works in treating patients with prostate cancer that progressed after surgery and/or radiation therapy.
In men with prostate cancer who do not have evidence of spread to bone or other sites on computed axial tomography (CAT) scan/bone scan but are still at significant risk of failing treatment with surgery or radiation alone, a combination of chemotherapy and hormone therapy is being given for 6 months followed by surgery to remove the prostate.
