Active clinical trials for "Prostatic Neoplasms"

RATIONALE: Obesity and overweight are associated with the risk of aggressive disease, and energy balance may play a major role in prostate cancer progression. PURPOSE: Randomized phase II trial to study the effectiveness of weight loss, via a healthy energy-restricted diet and exercise, in slowing or preventing disease progression in patients who have newly diagnosed prostate cancer.

The purpose of this phase II study is to evaluate the outcomes of patients treated with an investigational radiation regimen using stereotactic radiotherapy for oligometastatic prostate cancer and to establish efficacy (producing a desired result or effect) and safety in this setting.

Liposomal formulations are frequently used today in the treatment of cancer. LiPlaCis is the first targeted liposomal formulation with a tumour triggered release mechanism to undergo clinical development in oncology and it is expected that LiPlaCis will improve the therapeutic index of cisplatin compared to conventional cisplatin. Cisplatin is one of the most widely used drugs in the treatment of cancer due to its documented efficacy in a number of tumour types. Furthermore, it seems highly likely that cisplatin will remain an important drug in the future treatment of cancer. However, the drug is associated with a number of serious toxicities that complicates or necessitates discontinuation of therapy - e.g. need for pre-hydration, neurotoxicity, nausea and vomiting. Thus, there is a well-established need for improving cisplatin therapy in cancer patients. One option here is improving the formulation of the drug, so that a more selective up-take of cisplatin administered takes place at the tumour sites. Based on the results of the pre-clinical studies of LiPlaCis, it seems clear that LiPlaCis offers the potential to improve cisplatin therapy to the benefits of cancer patients. In a prematurely stopped Phase I Dutch study a Recommended Dose (RD) for a Phase II study was never reached which was the aim of the finished Phase I dose escalating part of this study for advanced or refractory solid tumors. In the Phase 2 part of this study, patients with advanced breast cancer with a biopsy examination showing a pattern compatible with sensitivity to LiPlaCis or patients with skin cancer will be included.

A drug-drug interaction study to investigate the potential pharmacokinetic interaction between MDV3100 and a cocktail of substrates for pioglitazone (CYP2C8 substrate), S-warfarin (CYP2C9 substrate), omeprazole (CYP2C19 substrate), and midazolam (CYP3A4 substrate).

Background: - Enzalutamide is a hormone therapy that is used to treat advanced prostate cancer. It is given after chemotherapy and surgery to help the body destroy the cancer cells. A new possible way of treating prostate cancer is using a vaccine that may help stimulate the immune system. It will help white blood cells recognize and kill the cancer cells in and around the prostate. Researchers want to see whether this vaccine, given with enzalutamide, is more effective at treating advanced prostate cancer than enzalutamide alone. Objectives: - To compare the safety and effectiveness of enzalutamide with and without vaccine therapy for advanced prostate cancer. Eligibility: - Men at least 18 years of age who have advanced castration-resistant prostate cancer. Design: Participants will be screened with a physical exam and medical history. Blood and urine samples will be collected. Imaging studies will be used to monitor the cancer before treatment. Participants will be separated into two groups. One group will have enzalutamide and the study vaccine. The other group will have enzalutamide alone. All participants will take enzalutamide once a day. They will take the drug during 4-week cycles of treatment. Treatment will be monitored with frequent blood tests and imaging studies. Participants will continue to take the study drug for as long as the cancer does not grow, and the side effects are not severe. The vaccine group of participants will also have the new study vaccine. They will have a single injection on the first day of the first study cycle. There will be regular booster injections afterward. There will be one on day 15 of the first cycle, the first day of the second cycle. The vaccine will then be given every 4 weeks for the next four cycles, and then every 12 weeks (every 3 cycles) thereafter. Participants will continue to have the study vaccine for as long as the cancer does not grow, and the side effects are not severe.

The purpose of the study is to determine the safety and clinical benefit of the combinations of abiraterone acetate and prednisone or abiraterone and dexamethasone in prostate cancer patients. Prednisone will be given at one of three different dose schedules. Dexamethasone will be given at one dose schedule. This will include looking at what side effects occur and how often they occur. In addition the impact of the study drug on quality of life and pain will be evaluated. The study will also collect data on subsequent treatment of patients after they come off the study drug (approximately 4.5 years after the start of study treatment of the first subject participating in the study). By analyzing blood samples, the study aims to identify if some markers could help to understand if the treatment with abiraterone is effective and also help to understand if patients can become resistant.

This pilot clinical trial studies the impact of radiation therapy on the immunogenicity of Sipuleucel-T. Patients with castration recurrent prostate cancer who are eligible for treatment with Sipuleucel-T and who have bone metastases are eligible.

For patients with prostate cancer and a high risk of lymph node involvement or confirmed pelvic lymph node metastases, radiotherapy of the whole pelvis is a treatment option. However, conventional radiotherapy of the pelvis has limited by gastrointestinal and urogenital side effects. The PLATIN trial investigates an intensity-modulated radiotherapy of the pelvic lymphatic drainage that spares small bowel, bladder and rectum. A higher dose is given during each session to the prostate or the prostate bed and to confirmed lymph node metastases. Prior to radiotherapy, two months of neoadjuvant antihormonal treatment are required, and continuation during radiotherapy and for a further two years are strongly recommended.

This randomized phase II trial studies if enzalutamide added to standard luteinizing hormone-releasing hormone (LHRH) analogue therapy will improve effects against prostate cancer compared to the standard therapy of LHRH analogue and bicalutamide. Hormone therapies stop the body from producing or block the effect of male sex hormones (testosterone). Enzalutamide blocks the effect of male sex hormones which are responsible for the growth of prostate cancer. Hormonal therapies that lower the level of testosterone are among the most effective treatments for prostate cancer that have spread to other areas of the body (metastasized). It is not yet known whether LHRH analogue therapy with bicalutamide is more effective than LHRH analogue therapy with enzalutamide in treating prostate cancer.

This is the first study where BAY2010112 is given to humans. Patients with castration resistant prostate cancer will be treated. Every patient will receive drug treatment, there is no placebo group. Patients will receive different dosages of BAY2010112 to determine the safety, tolerability and maximum tolerated dose (MTD) of BAY2010112. The study will also assess the pharmacokinetics and the clinical efficacy of BAY2010112. BAY2010112 will be given daily as subcutaneous injection or as continuous intravenous infusion. Treatment will be stopped if the tumor continues to grow, if side effects, which the patient cannot tolerate, occur or if the patient decides to exit treatment.
