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: Diagnostic procedures, such as positron emission tomography using carbon-11 acetate, may help find metastases from prostate cancer and may help predict whether prostate cancer will come back after treatment. PURPOSE: This clinical trial is studying how well positron emission tomography using carbon-11 acetate works in finding metastases and predicting recurrence in patients with prostate cancer who are at risk for recurrence after treatment.
RATIONALE: Chemoprevention is the use of certain drugs to keep cancer from forming, growing, or coming back. The use of calcitriol may prevent prostate cancer. It is not yet known whether calcitriol is more effective than observation in preventing prostate cancer. PURPOSE: This randomized phase II trial is studying how well calcitriol works in preventing prostate cancer in patients with prostatic intraepithelial neoplasia.
Population pharmacokinetic and pharmacodynamic data from Study FE200486 CS06 and FE200486 CS02 provided further knowledge of the optimal dose regimens for FE200486 (degarelix). Both studies were to guide dose selection for phase III. In addition, safety and tolerance data were generated.
Participants responding well in Study FE200486 CS06 (NCT00117949) were given the opportunity to continue treatment with degarelix under a clinical study until FE200486 was available on the market or until the study was discontinued. Study FE200486 CS06A was to provide knowledge of the long-term safety and tolerability of FE200486.
This was an extension study for the study FE200486 CS14 (NCT00116779). Each participant was to be treated until he was discontinued or withdrawn from the study, or a marketing authorization for degarelix had been obtained. The study was terminated when all ongoing participants had been treated for at least 5 years.
The purpose of the study was to contribute, along with other such dose-finding studies, to the identification of the most effective treatment regimen for a one month depot injection of degarelix in the treatment of prostate cancer by a rapid and sustained suppression of testosterone.
The rationale of the study was to evaluate different degarelix dosing regimens for a three-month interval that was to produce and maintain castration in prostate cancer patients through immediate and prolonged testosterone suppression, and to provide confirmatory evidence of the safety of degarelix.
This clinical study was to determine if the use of 6 months of total androgen suppression (hormonal therapy) when added to radiation therapy for localized-high risk prostate cancer would improve overall survival.
This is a multi-center, open-label, dose finding study of CV787 adenovirus in patients with hormone refractory metastatic prostate cancer. Patients will receive treatment intravenously at one of up to nine dose levels, each containing three to six patients.
