Filter by:Androgen (a male sex hormone) deprivation is the standard therapy for metastatic prostate cancer and results in regression or control of disease in 80-85% of patients. This hormone therapy results in a progression-free survival of 12-18 months and overall survival of 24-30 months. However, all patients ultimately develop hormone-refractory prostate cancer (HRPC). Management of HRPC patients is a significant challenge for both patient and physician. Neither past nor current chemotherapy regimens have shown curative potential in patients with HRPC. Thus new treatment strategies are a high priority. A major focus of new treatment strategies is to enlist the aid of the immune system, particularly the development of prostate cancer vaccines. There has been a number of studies using dendritic cell based vaccines and the treatment has been well tolerated. Specific T-cell immune responses have been observed and occasional evidence for tumor regression. A reduction in serum prostate-specific antigen (PSA) has been observed as well. Lengthening the time-to-progression and delays in the onset of bone pain have been observed in subsets of patients with HRPC. The initial preclinical observations suggesting that a granulocyte-macrophage colony-stimulating factor (GM-CSF) gene transduced allogeneic (GVAX) prostate cancer vaccine may be efficacious in poorly immunogenic cancers were reported. The objective of this study is to evaluate the safety and immunologic effects of vaccinations with Allogeneic Prostate GVAX® (CG1940 & CG8711) in patients made lymphopenic by treatment with chemotherapy and infused with autologous peripheral blood mononuclear cells (PBMC). Clinical observations and laboratory measurements will be monitored to evaluate safety, toxicity and immune responses. Additionally, the effects of treatment on serum PSA levels and tumor response will be evaluated.
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. R-flurbiprofen may be effective in delaying the recurrence of localized prostate cancer. PURPOSE: Randomized phase II trial to study the effectiveness of R-flurbiprofen in treating patients who have localized prostate cancer at risk of recurrence following radiation therapy and/or prostatectomy.
The purposes of this study are to determine if DN-101 plus Taxotere lowers PSA levels, delays or limits disease progression and is safe with minimal side effects.
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 DHA-paclitaxel in treating patients who have metastatic prostate cancer that has not responded to hormone therapy.
RATIONALE: Drugs such as SU006668 may stop the growth of solid tumors by stopping blood flow to the tumor. PURPOSE: Phase I trial to study the effectiveness of SU006668 in treating patients who have advanced solid tumors.
RATIONALE: Radiolabeled monoclonal antibodies can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining monoclonal antibody therapy and chemotherapy with peripheral stem cell transplantation may be an effective treatment for metastatic prostate cancer. PURPOSE: Phase I trial to study the effectiveness of monoclonal antibody therapy plus chemotherapy followed by peripheral stem cell transplantation in treating patients who have metastatic 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. Combining more than one drug may kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy in treating patients who have metastatic prostate cancer that has not responded to hormone therapy.
RATIONALE: Vaccines made from a person's peripheral stem cells may make the body build an immune response to kill tumor cells. PURPOSE: Phase I trial to study the effectiveness of vaccine therapy in treating patients who have metastatic 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. Giving more than one drug may kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy in treating patients who have prostate cancer that has not responded to hormone therapy.
RATIONALE: Radiation therapy uses high-energy radiation to damage tumor cells. Brachytherapy uses radioactive material that is placed directly into or near the tumor. Brachytherapy may kill more tumor cells. PURPOSE: Phase I/II trial to study the effectiveness of brachytherapy in treating patients who have recurrent prostate cancer that has not responded to standard therapy.
