Active clinical trials for "Prostatic Neoplasms"

This phase I trial studies the side effects and best way to give enzalutamide, radiation therapy, and hormone therapy in treating patients with intermediate or high-risk prostate cancer. Androgens can cause the growth of prostate cancer cells. Antihormone therapy, such as enzalutamide, may lessen the amount of androgens made by the body. Radiation therapy uses high energy x rays to kill tumor cells. Giving enzalutamide, radiation therapy, and hormone therapy may be an effective treatment for prostate cancer.

This phase II trial studies how well pembrolizumab works in treating patients with prostate cancer that has spread to other places in the body and keeps growing even when the amount of testosterone in the body is reduced to very low levels despite previous treatment with enzalutamide. Monoclonal antibodies, such as pembrolizumab, may block tumor growth in different ways by targeting certain cells.

Prostate cancer, the most frequently diagnosed cancer among occidental men, is associated with a major individual and societal burden. Although still controversial, the literature suggests that a high consumption of omega-3 fatty acids (ω3) has protective effects against prostate cancer. One of the proposed mechanisms of action of ω3 lies in their anti-inflammatory properties. In addition, there are some observational evidences suggesting an association of ω3 intake with a lower rate of depression in cancer patients. However, no clinical study has tested the efficacy of ω3 supplementation on psychological and quality of life outcomes in that population. Several evidences point to a possible involvement of inflammation in psychological issues. Reducing the systemic inflammatory state may have beneficial impact on the quality of life of these patients. Preliminary work from this team of investigators, in a cohort of patients managed with active surveillance for their low-grade prostate cancer, show a strong inverse association between the risk of prostate cancer progression (to high-grade) and the level of prostatic eicosapentanoic acid (EPA- a type of ω3). HYPOTHESIS: EPA-rich monoglycerides fish oil (MAG-EPA) has global positive effects on prostate cancer cell proliferation, inflammation and on the patient's psychosocial functioning and quality of life. The investigators propose a double blind, randomized controlled clinical trial. 130 consecutive patients suffering from high-risk prostate cancer who choose to be treated by radical prostatectomy will be eligible to this study. The presence of high-grade cancer will be mandatory. The intervention, a daily supplementation with 3g supplement of fish oil monoglycerides rich in EPA, vs. placebo capsules containing high oleic sunflower oil, will start six weeks before the prostatectomy and will continue for one year after surgery. The potential confounding variables will be measured before the start of the intervention: age, anthropometric parameters, stage and clinical and pathological tumor grade (Gleason score), pre-operative level of prostate specific antigen and diet. This project proposes a simple intervention by dietary supplementation that could eventually help to reduce the incidence and/or progression of prostate cancer, and the consequences of its treatment, and thus could contribute to diminish the heavy individual and societal burden of prostate cancer. The clinical data generated by this trial will serve as solid basis for a large-scale phase III clinical trial.

The purpose of this study is to find out what effects, good and/or bad, taking ipilimumab with abiraterone acetate plus prednisone has on the patient and the prostate cancer. Abiraterone acetate plus prednisone are drugs that lower testosterone (testosterone stimulates prostate cancer growth). Abiraterone acetate plus prednisone is a treatment for patients with prostate cancer. Abiraterone acetate plus prednisone has not been used together with ipilimumab before. This study will test how they work together. Each patient will receive abiraterone acetate, prednisone and ipilimumab.

The primary objective of the trial is to assess if upfront combination of enzalutamide and Ra223 improves radiological progression-free survival (rPFS1) compared to enzalutamide single agent in CRPC patients metastatic to bone

Multi-centre Randomized Clinical Trial: 106 patients with confirmed unilateral high-volume low risk (Gleason score 3 + 3) or intermediate risk prostate cancer (Gleason score 3 + 4) will undergo an IRE treatment. These patients will be randomized into one of the two groups of the study. Group 1: Focal ablation of the prostate at the side of the positive biopsies (focal-ablation) Group 2: Extended ablation of the prostate (extended ablation) Patients will have an ultrasound of the prostate and the imaging data will be entered into the Planning Software system of the IRE-device. The volume of the prostate is measured and a specified ablation zone will be determined. The patients will be admitted for overnight stay in the hospital on the morning of the scheduled IRE procedure. The IRE will be performed under general anaesthetic and the specified zone identified in the planning stage will be ablated. Two to four IRE electrode needles will be placed into the prostate under ultrasound image guidance with a perineal approach using a brachytherapy grid. When the needles are in place, electric pulses of one to two minutes duration are used to ablate the specified zone. The total procedure time will be approximately 1 hour. Safety data will be collected and patients will be followed up at 1 day post-operatively, 1 month, 3 months, 6 months and 1, 2 and 3 year(s) post IRE.

This research study is a Phase II clinical trial, which tests the safety and effectiveness of an investigational combination of drugs to learn whether they work in treating a specific cancer. "Investigational" means that the combination of drugs is still being studied and that research doctors are trying to find out more about it, such as the safest dose to use and the side effects they may cause. It also means that the FDA has not yet approved the combination. The two drugs being tested in this study are tivozanib and enzalutamide. Enzalutamide has been approved by the FDA for treatment of prostate cancer. On the other hand, tivozanib is still investigational, and has not been tested in a combination with enzalutamide before. Enzalutamide is an androgen receptor antagonist (it blocks the activity of the male sex hormones). Prostate cancers are initially dependent on the male hormone testosterone for growth. Hormonal therapies that lower testosterone or block the ability of testosterone to act at the level of the prostate cancer are currently among the most effective treatments for prostate cancers taht have spread to other body organs (metastasized). The effectiveness of hormonal treatments, however, is not permanent, and over time many prostate cancers progress in spite of these treatments. Enzalutamide is a drug that has been proven to help delay the progression of advanced prostate cancer on average for about 8 months. Tivozanib is an anti-angiogenesis medicine that fights different types of cancer by blocking the blood supply to the tumor, so that the tumor does not receive the nutrients it needs to grow. The main goal of this study is to determine whether the combination of tivozanib and enzalutamide is more effective in delaying the progression of disease than when enzalutamide is given alone. This study will also determine whether treatment with the combination of the tivozanib and enzalutamide will have more side effects then treatment with enzalutamide alone.

The purpose of this study is to evaluate the efficacy and safety of apalutamide in adult men with high-risk non-metastatic castration-resistant prostate cancer.

RATIONALE: Radical prostatectomy is surgery to remove the entire prostate. Radiation therapy uses high-energy x-rays or other types of radiation to kill tumor cells. Sometimes the tumor may not need treatment until it progresses. In this case, active surveillance may be sufficient. It is not yet known which treatment regimen is more effective for localized prostate cancer. PURPOSE: This randomized phase III trial is studying active monitoring to see how well it works compared with radical prostatectomy or radiation therapy in treating patients with localized prostate cancer.

The first technology is called high dose rate brachytherapy. Brachytherapy is sometimes called internal radiation therapy. High dose rate brachytherapy is a procedure that involves temporarily placing radioactive material inside the patient's body for about 10-20 minutes. Then, the remainder of the radiation treatment will be given over a 3 week period using stereotactic body radiation therapy (SBRT). SBRT is a novel treatment modality that involves the delivery of very high individual doses of radiation to tumors with high precision. This allows the doctor to deliver the same amount of radiation in a much shorter time. The purpose of this study is to determine the safety of brachytherapy when combined with hypofractionated SBRT.
