Active clinical trials for "Prostatic Neoplasms"

This trial will evaluate the feasibility, toxicity, and efficacy of docetaxel/estramustine, as in the adjuvant therapy of patients with high-risk prostate cancer after definitive local therapy.

RATIONALE: Learning about changes in DNA over time in patients with prostate cancer undergoing diet and lifestyle changes may help doctors learn about the long-term effects of these changes on disease progression. PURPOSE: This clinical trial is studying nutrition and lifestyle changes in patients with previously untreated stage I or stage II prostate cancer.

The purpose of this study is to evaluate the safety of docetaxel administered every 3 weeks repeatedly for 11 and more cycles and in combination with daily prednisolone for metastatic hormone refractory prostate cancer.

A phase 3, open-label, parallel group, one year trial comparing the efficacy and safety of degarelix 3-month depot with the established therapy goserelin acetate 3-month implant in patients with prostate cancer.

This research is being done to test an investigational drug, called itraconazole, in the treatment of prostate cancer. Itraconazole is approved by the Food and Drug Administration (FDA) for the treatment of various fungal infections such as fingernail/toenail infections and other more serious fungal infections. The word "investigational" means that itraconazole is not approved for use in people with cancer. However, the FDA is allowing the use of itraconazole in this research study. Itraconazole has been shown to have activity against cancer (including prostate cancer) in the laboratory, but has not been tested against cancer in humans. The purpose of this study is to find out: If itraconazole is safe when given at two different doses How itraconazole affects prostate specific antigen (PSA): a blood test that measures substances released by prostate cancer Whether itraconazole can delay further prostate cancer growth and spread How itraconazole affects other markers of prostate cancer

RATIONALE: Diagnostic procedures, such as technetium Tc 99m demobesin-4 followed by single-photon emission computer tomography, CT scan, and MRI, may help find prostate cancer and learn the extent of disease. PURPOSE: This phase I trial is studying the side effects of technetium Tc 99m demobesin-4 and to see how well it works for imaging procedures in patients with prostate cancer.

The current study involves a novel and aggressive therapeutic approach for patients' prostate cancer. In addition, the investigators propose to administer hormonal therapy to patients with an especially high risk: those with initial Gleason scores of > 6, PSA > 10 ng/ml, T3/T4 primary tumors, and those found to be node positive (N+). The use of hormonal therapy in these specific settings correlates with our current standard of care. IMRT is better able to spare and protect normal tissues from receiving radiation than 3-D conformal RT. The radiotherapy would be followed by continued hormonal therapy for a total of 6 months in those who have one of the following Gleason 7 and PSA 10-20 and as per the previous version of this trial, 1 year similar to that delivered by the EORTC for higher risk patients, (those with initial Gleason scores of > 8, PSA > 20 ng/ml, or T3/T4 tumors). Those found to be N(+) would have the hormonal therapy continued indefinitely or until disease progression occurred in a manner analogous to the Messing et. al. series in prostatectomy patients. The goals are to develop and administer a program of treatment that includes the most recent developments in imaging, integrating data from both the CT scan and the ProstaScint scan to optimize prostate cancer RT. The CT scan will be used for staging and to determine the exact location of the entire prostate which will receive a reasonable dose of RT. The ProstaScint will be used to assess the spread of disease to lymph nodes as well as to determine the exact location of the tumor within the prostate gland. This region will then be boosted to a tumorcidal dose. The investigators then plan to monitor the toxicity and outcome of this treatment. The investigators expect that this program of radioimmunoguided IMRT will likely result in similar or less toxicity and increased cure rates when compared to conventional radiotherapy and standard IMRT programs.

This study is intended to test an experimental new drug called, EMD 525797 (Study Drug). This drug is not yet approved for sale and has only been tested in a small number of people to date (prior to this study starting another research study was carried out involving 37 healthy volunteers receiving the Study Drug). Until more is known about this Study Drug, it can only be used in research studies. This research study is planned to answer important questions about how the Study Drug is tolerated and how it may work in patients with prostate cancer with bone metastases. This is a small study which is expected to include 24 patients, and will be conducted in approximately 3 hospitals in Germany and 1 hospital in Brussels, Belgium. The study will last until the last patient has had their last study visit which is expected to be about 18 months in total.

Vitamin D promotes the differentiation of prostate cancer cells, maintains the differentiated phenotype of prostate epithelial cells, and can induce prostate cancer cell death, raising the possibility that vitamin D deficiency over time promotes the progression of subclinical prostate cancer to clinical disease. The investigators propose to conduct a clinical study aimed at measuring the efficacy of vitamin D3 (4000IU/day) supplementation in Veterans diagnosed with low-risk, early-stage prostate cancer, who elect to have their disease monitored through active surveillance. The successful completion of this proposed clinical study will allow us to determine whether correcting vitamin D deficiency in Veterans diagnosed with early-stage prostate cancer will prevent progression of their disease and improve their prognosis.

RATIONALE: Efavirenz may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. PURPOSE: This phase II trial is studying how well efavirenz works in treating patients with metastatic prostate cancer.
