Active clinical trials for "Prostatic Neoplasms"

This is a research study for advanced prostate cancer. An experimental drug called AN-152 (also known as AEZS-108) will be used. The purpose of this study is to test the safety, tolerability and benefits of an experimental drug called AN-152. The participants tumor will be tested for expression of this receptor (using an old biopsy). If the participants cancer does not have this receptor, participants will not be eligible to participant in this study. AN-152 (AEZS-108) is administered intravenously (IV) over 2 hours and will be given at the specified dose every 3 weeks. Premedication with dexamethasone 8mg is recommended. Participants will continue treatment until death, disease progression, unacceptable toxicity, participants refusal, treatment delay >3 weeks, or the completion of 6 cycles. Continuation beyond 6 cycles is left at the discretion of the study doctor. The study is planned to last 2 years. Up to 55 (up to 18 for the Phase I portion, up to 37 for the Phase II portion).

To assess the effect of neo-adjuvant GnRH antagonist, degarelix, versus LHRH agonist on intratumoral levels of androgens.

This study will investigate the feasibility of using technology of ultrasound guided HDR brachytherapy to focally increase dose to regions within the prostate that are heavily infiltrated with cancer. Such regions, referred to as dominant intraprostatic lesions (DIL) can be visualized using diffusion contrast enhanced MRI employing an endo-rectal coil. The magnetic resonance (MR) images can be fused with the planning transrectal ultrasound (TRUS) prior to the brachytherapy procedure to design a dose distribution that will encompass the malignant volume with higher than the prescription dose. By its nature, brachytherapy has subvolumes that receive (for example)125% of the prescription dose or 150% of the prescription dose. With TRUS-guided and TRUS-planned HDR these areas can be manipulated to coincide with the DIL. The limit of dose escalation has been reached at whole prostate external beam doses of 81-86 Gy and still failure rates for intermediate and high risk disease are unacceptable. There is much interest in focal dose escalation and TRUS-guided HDR brachytherapy is perfectly suited to achieving this.

When given to men with recurrent prostate cancer, the investigators hypothesize that POMx is effective in slowing the rise of PSA as measured by PSA doubling time in men following initial therapy for prostate cancer. Further, the investigators believe that POMx will be shown to be safe and well tolerated.

This randomized phase II trial is studying the side effects and how well giving cediranib maleate together with or without dasatinib works in treating patients with hormone-resistant prostate cancer resistant to treatment with docetaxel. Cediranib maleate and dasatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth or by blocking blood flow to the tumor. It is not yet known whether giving cediranib maleate together with dasatinib or alone is an effective treatment for prostate cancer.

We will study the effect of dietary intervention in patients with prostate cancer. Outcomes include serum PSA kinetics, as well as biomarkers of inflammation, antioxidant status, oxidative stress and oxidative damage in blood cells, plasma, urine and prostate tissues

To evaluate the safety, tolerability, efficacy, and pharmacokinetics of MDX-1106 when administered to patients with advanced non-small cell lung cancer, colorectal cancer, malignant melanoma, clear cell renal cell cancer or hormone refractory prostate cancer

The objective of this study is to establish the safety of MRI targeted laser thermal treatment for men with biopsy confirmed early stage low grade single sector prostate cancer.

Giving diindolylmethane, a substance found in cruciferous vegetables, may help doctors learn more about how diindolylmethane is used by the body. This randomized phase I trial is studying the side effects and best dose of diindolylmethane compared with a placebo in treating patients undergoing radical prostatectomy for stage I or stage II prostate cancer.

Background: No treatment is known to improve survival for prostate cancer patients who have not been helped by previous treatments with hormones and chemotherapy. An experimental vaccine called prostate specific antigen (PSA)/TRICOM contains genes for a protein produced by prostate cancer cells called prostate-specific antigen (PSA). The vaccine can trigger the immune system to make cells that may be able to recognize and attack the cancer cells that make PSA. Granulocyte macrophage colony stimulating factor (GM-CSF) is an approved drug that is usually given to increase a patient's white blood cell count or to stimulate the immune system. 1Samarium-153-ethylene diamine tetramethylene phosphonate (53Sm-EDTMP) is a radioactive drug that has been approved for many years to treat advanced prostate cancer. It is given through a vein and can be targeted directly to tumors in the bone where it can relieve pain caused by bone lesions. Radiation also increases the level of certain proteins inside the tumor, making it easier for the immune system to find and kill the tumor cells. When laboratory mice were given just vaccine, just radiation, or a combination of both, the combination was most effective in treating tumors. Objectives: -To determine if combined treatment with PSA/TRICOM vaccine and 153Sm-EDTMP radiation can delay progression of prostate cancer better than radiation alone. Eligibility: -Patients who have advanced prostate cancer that has worsened despite treatments with hormones, have two or more bone lesions related to their prostate cancer, and have had prior treatment with docetaxel chemotherapy. Design: Patients are randomly assigned to receive radiation alone (Arm A) or radiation with vaccine and sargramostim (Arm B). Arm A receives 153Sm-EDTMP radiation starting on study day 8 and repeated every 12 weeks. Arm B receives a priming vaccine on study day 1 and radiation on day 8. Radiation therapy is repeated every 12 weeks. Boosting vaccines are given on days 15 and 29 and then monthly. GM-CSF is given with each vaccination (on the day of the vaccination and for the next 3 days) to enhance the immune response. Vaccinations and GM-CSF are given as injections under the skin, usually in the thigh. Radiation therapy is given through a vein. Patients are monitored regularly with physical examinations, blood and urine tests, and scans to evaluate safety and treatment response. Patients who are human leukocyte antigen serotype within HLA-A A serotype group (HLA-A2)-positive undergo apheresis, a procedure similar to donating blood, for obtaining immune cells called lymphocytes to measure the immune response to the vaccine.
