Active clinical trials for "Prostatic Neoplasms"

RATIONALE: Androgens can cause the growth of prostate cancer cells. Antihormone therapy, such as flutamide, bicalutamide, leuprolide, buserelin, and goserelin, may lessen the amount of androgens made by the body. Radiation therapy uses high-energy x-rays to kill tumor cells. Drugs used in chemotherapy, such as docetaxel, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. It is not yet known whether giving androgen suppression therapy together with radiation therapy is more effective with or without docetaxel in treating prostate cancer. PURPOSE: This randomized phase III trial is studying androgen suppression therapy, radiation therapy, and docetaxel to see how well they work compared with androgen suppression therapy and radiation therapy in treating patients with high-risk localized prostate cancer. CLOSURE: This trial closed to further accrual in November 2009. The study endpoints will not be reached.

Subjects will be asked to participate in this clinical trial to examine the safety of 2-deoxyglucose (an agent which is quite similar to glucose) in the treatment of solid tumors and hormone refractory prostate cancer. This agent works by blocking the metabolism of glucose in the cells of the body. Although all cells require glucose for metabolism, it is believed that cancer cells require significantly more glucose than normal cells to grow. Therefore, even slight effects of glucose metabolism in cancer cells might result in the shrinkage of certain cancers. This agent has been given to humans before and has only caused mild nausea, vomiting and glucopenia (low blood sugar) at the doses given in these studies. This study will further examine the safety of 2-deoxyglucose in the treatment of advanced solid tumors and hormone refractory prostate cancer. The information obtained in this study will be used to design future clinical studies with 2-deoxyglucose. Subjects will be asked to take an oral solution of 2-deoxyglucose daily, by mouth, while on this study. They will be asked to have CT Scans, Bone Scans, and optional PET (Positron Emission Tomography) Scans prior to starting this study. PET scans will also be performed shortly after the start of the study and after 2 cycles (6 weeks) of therapy. Subjects will be asked to have a comprehensive physical examination and blood work prior to the start of the study. During the first 2 cycles of the study subjects will be asked to have blood drawn at different time intervals for the first 2 days of each cycle. While on the study, they will be asked to return to the clinic at intervals of 1 week for a physical examination and blood tests. Subjects will also be asked to have CT Scans and Bone Scans at intervals of 9 weeks while on the study.

The IMPACT study is an international targeted prostate screening study of men at increased prostate cancer risk due to the presence of known pathogenic mutations in BRCA1 and BRCA2 genes. There are only approximately 150 men with a known BRCA1 or BRCA2 mutation in the UK. Research has shown that these men are at an increased risk of developing prostate cancer but more information is needed about the pathogenesis of prostate cancer in this defined group and the role of screening in these men. The study will offer annual PSA screening to these men to determine the incidence of prostate cancer in this group. The study will also look at new markers of early prostate cancer in this cohort. The power calculations for this study are 850 carriers and 850 controls (age-matched men without BRCA1/2 mutations). It is therefore essential to gain international collaboration to meet the target of recruiting 850 men with these known mutations and a control group of 850 men who have tested negative for a known familial mutation.

RATIONALE: Estrogen may cause the growth of prostate cancer cells. Hormone therapy using fulvestrant may fight prostate cancer by blocking the use of estrogen by the tumor cells. PURPOSE: This phase II trial is studying how well fulvestrant works in treating patients with recurrent prostate cancer.

RATIONALE: Isotretinoin may help prostate cancer cells become more like normal cells, and to grow and spread more slowly. Interferon alfa-2b may interfere with the growth of tumor cells. Drugs used in chemotherapy, such as docetaxel and estramustine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving isotretinoin and interferon alfa-2b together with docetaxel and estramustine may kill more tumor cells. PURPOSE: This phase II trial is studying how well giving isotretinoin and interferon alfa-2b together with docetaxel and estramustine works in treating patients with metastatic prostate cancer that did not respond to hormone therapy.

RATIONALE: Licorice root extract contains ingredients that may slow the growth of tumor cells. Drugs used in chemotherapy, such as docetaxel, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving licorice root extract together with docetaxel may be an effective treatment for prostate cancer. PURPOSE: This phase II trial is studying the side effects and how well giving licorice root extract together with docetaxel works in treating patients with metastatic prostate cancer that did not respond to hormone therapy.

RATIONALE: Conformal radiation therapy uses a 3-dimensional (3-D) image of the tumor to help focus thin beams of radiation directly on the tumor. Giving conformal external-beam radiation therapy in higher doses over a shorter period of time may kill more tumor cells and have fewer side effects. Androgens can cause the growth of prostate cancer cells. Hormone therapy, such as leuprolide acetate, may lessen the amount of androgens made by the body. It is not yet known whether radiation therapy is more effective when given together with or without hormone therapy in treating patients with prostate cancer who have undergone surgery. PURPOSE: This randomized phase III trial is studying radiation therapy to see how well it works compared with radiation therapy given together with hormone therapy in treating patients who have undergone surgery for stage I, stage II, or stage III prostate cancer.

The goal of the Phase I part of this clinical research study is to find the highest tolerable dose of Revlimid® (lenalidomide) that can be given in combination with paclitaxel to patients with prostate cancer who have failed treatment with taxanes. The goal of the Phase II part of this clinical research study is to learn if lenalidomide and paclitaxel can help to control prostate cancer. The safety of this combination treatment will be studied in both phases of the study. UPDATE: Study was terminated early due to slow accrual as a Phase I dose escalation study, without progression to Phase II study portion.

The purpose of this research study is to determine the safety of giving ketoconazole, hydrocortisone and dutasteride (KHAD) with lapatinib. Safety is primarily based on dose limiting toxicity (DLT) evaluation at various dose levels (DL). The investigators believe that there is evidence in castrate resistant prostate cancer (CRPC) that two growth factor receptors (EGFR and Her 2/Neu) are increased in prostate cancer (PCa) cells. Both these receptors are turned off by the drug lapatinib. By adding lapatinib, the investigators hope that signaling from the receptors will be turned off and therefore make the participant's cancer more responsive to KHAD treatment.

This randomized phase II trial is studying how well giving docetaxel and prednisone together with or without cediranib works in treating patients with metastatic 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. Cediranib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor. Giving docetaxel together with prednisone, with or without cediranib, may kill more tumor cells.
