Active clinical trials for "Prostatic Neoplasms"

The purpose of this study is to provide access to abiraterone acetate for patients who have completed 12 cycles of abiraterone acetate treatment in Clinical Study COU-AA-001 and continue to receive clinical benefit from this treatment.

Assess the efficacy and safety of Triptorelin pamoate 3M formulation (11.25mg) when administered by subcutaneous route.

This randomized pilot clinical trial studies sipuleucel-T with or without deoxyribonucleic acid (DNA) vaccine therapy in treating patients with prostate cancer that has not responded to previous treatment with hormones and has spread to other places in the body. Vaccines may help the body build an effective immune response to kill tumor cells. It is not yet known whether giving sipuleucel-T vaccine works better with or without DNA vaccine therapy in treating prostate cancer.

Prostate cancer is the second leading cause of mortality in men, representing 10 deaths about of 100 cancers (INVS 2009). Treatment for metastatic prostate cancer, when becoming resistant to hormone-treatment, is mostly resumed to a relatively ineffective chemotherapy (Docetaxel/TAXOTERE®) (1). Recently, numerous clinical and preclinical works showed that Metformin could represent an excellent candidate for treatment of advanced prostate cancer. This is a widely prescribed drug, for type 2 diabetes, with clinical advantage of exhibiting very rare serious side effects. On the other hand, the use of this molecule in patients was associated with a decrease of tumors incidence, in particular prostate cancer (2). Numerous in vitro and in vivo studies support its role as an anti-cancer drug, in several cell lines (3). These experimental results are consistent with a clinical trial pilot study, performed in colorectal cancer, showing anti proliferative effect of Metformin (4). In the field of prostate, F. Bost in J.F. Tanti's team (INSERM U895, Nice) demonstrated that Metformin inhibits cell viability of human prostate cancer cells, via mTOR downregulation and decrease tumor growth in a xenograft model (5). Furthermore, preclinical data performed by this team showed that Metformin increased significantly apoptosis induced by TAXOTERE®. Therefore, by targeting specifically cancer cell metabolism, Metformin offers new promising therapeutic strategy. The primary objective of this randomized study is to evaluate the biological efficacy of Metformin combination with TAXOTERE® in patients with metastatic hormone-refractory prostate cancer. To achieve this purpose, PSA response rate will be evaluated according to ASTRO definitions (Bubley, Carducci et al. 1999). Concurrently, secondary endpoints will be under investigation in order to evaluate the clinical response according to RECIST criteria, the overall and free-progression survival and the quality of life. Toxicity assessment will also be performed regarding to this drug combination. Considering the well tolerability of Metformin and the first clinical and pre-clinical data reports of it use in cancer treatment, combining Docetaxel (TAXOTERE®) with Metformin may represent a promising strategy for treatment of hormone-refractory prostate cancer.

This phase I/II trial studies the side effects and best dose of alisertib when given together with abiraterone acetate and prednisone and to see how well it works in treating patients with hormone-resistant prostate cancer. Alisertib and abiraterone acetate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Androgens can cause the growth of prostate cancer cells. Drugs, such as abiraterone acetate, may also lessen the amount of androgens made by the body. Drugs used in chemotherapy, such as prednisone, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving alisertib, abiraterone acetate, and prednisone together may be an effective treatment for prostate cancer.

The primary objective of this study is to evaluate the safety and feasibility of Magnetic Resonance Image (MRI) guided focal prostate cancer laser thermal ablation in males, ages 40-80 with biopsy confirmed early clinical stage prostate cancer (T1c or T2a) with an identifiable lesion on mutliparametric MRI, with a Prostate Specific Antigen (PSA) of < 15ng/ml, who have not yet undergone pelvic radiation or hormonal deprivation therapy.

RATIONALE: Radiation therapy uses high-energy x-rays and other types of radiation to kill tumor cells. Specialized radiation therapy, such as intensity-modulated radiation therapy, that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. PURPOSE: This clinical trial studies intensity-modulated external beam radiation therapy in treating patients with prostate cancer.

This is a randomized, double blind, placebo controlled trial of immunotherapy with autologous antigen-loaded dendritic cells (Provenge, APC8015) for asymptomatic, metastatic, hormone-refractory prostate cancer.

RATIONALE: SB939 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 SB939 works in treating patients with recurrent or metastatic prostate cancer.
