Active clinical trials for "Prostatic Neoplasms"

The main purpose is to compare the detection rate of 20-core versus 12-core prostate biopsy. The secondary objective is to evaluate pain perception using a validated scale to compare the analgesia provided by the two different local anesthesia schemes. Data will be prospectively collected from patients who will undergo prostate biopsy in a single high volume urology center. The patients will be randomized to two different biopsy samplings and two local anesthesia schemes.

This study evaluates whether a broccoli intervention (≥ 4 weeks) will result in differences in tissue sulphate levels in men scheduled for prostate biopsies. Comparisons will be made between participants randomised to the broccoli-rich diet and those randomised to the non-intervention arm.

This Phase II, open-label, three-arm randomized controlled trial (RCT) will investigate the effects of 12 weeks of aerobic exercise vs. 12 weeks of resistance exercise vs. usual care in men with metastatic castration resistant prostate cancer to determine the safety, feasibility, and tolerance of exercise; quality of life indicators, and a prognostic score.

This pilot phase I trial studies copper Cu 64 TP3805 (Cu-64-TP3805) positron emission tomography (PET)/computed tomography (CT) in detecting cancer in patients with prostate cancer undergoing surgery to remove the entire prostate and some of the tissue around it (radical prostatectomy). Many patients with benign lesions must undergo biopsy to test the lesion. Cu-64-TP3805 is a radioactive substance that attaches to cancer cells but not normal cells. PET/CT uses a scanner to make detailed, computerized pictures of areas inside the body where the radioactive substance is lighting up. Using Cu-64-TP3805 PET/CT scans and comparing them with cancer tissue obtained from surgery may help doctors learn whether Cu-64-TP3805 PET/CT can accurately detect prostate lesions and determine whether they are cancerous or benign, which may minimize the need for prostate biopsies.

This is a multicentre, phase II, randomized, open label study to evaluate the efficacy and safety of monthly Radium 223 in prolonging the off treatment interval of men with localized prostate cancer receiving intermittent androgen ablation therapy for a rising PSA post-radiation or post-prostatectomy, who are at high risk for occult metastases.

The goal of this clinical research study is to learn about the safety and the effectiveness of using AmnioFix® (dehydrated human amnion/chorion membrane, also called dHACM) to help improve the return of erectile function and bladder control in patients after robotic assisted laparoscopic radical prostatectomy (RARP). dHACM is a section of tissue made from part of the placenta donated by a mother during a C-section. It looks like a small piece of tissue paper and is wrapped around the nerve bundles in the surgical area. The tissue may help the body's normal healing process.

This clinical study will evaluate the role of combination therapy of docetaxel followed by Provenge for patients with metastatic castration-resistant prostate cancer (CRPC, (prostate cancer that is resistant to medical or surgical treatments that lower testosterone). The purpose of this study is to look at the combination therapy of docetaxel followed by Provenge to correlate the immunological biomarkers with clinical results for therapy. Biomarkers are genes, proteins and other molecules that affect how cancer cells grow, multiply, die and respond to other compounds in the body. The study drugs are approved by the Food and Drug Administration (FDA). Treatment will be administered on an outpatient basis. Patients will receive 6 cycles of docetaxel followed by Provenge. Docetaxel is an antineoplastic (chemotherapy that affects cancer cell growth) agent. Docetaxel dose of 75 mg/m2 will be given intravenously as a 1-hour infusion every 21 days on Day 1 for 6 cycles. Provenge is an immunotherapy (vaccine made from patient's own blood cells) that reprograms immune cells to attack cancer. A course of therapy consists of three doses of Provenge administered at 2-week intervals. The strategy aims to determine whether cytokine production and T cell infiltration of tumor cells could favor regression using a combination of chemotherapy plus vaccine. Tissue endpoints will include biopsies prior to first chemotherapy and first vaccine therapy and at the end of each therapy. Prostate cancer tissue infiltrates will be studied for expression of CD3, CD4, CD8, CD25/FOX3P, CD56, CTLA-4, PD-1, and Ki67. Additional immunological endpoints will be secondary antigen spread and various cytokine biomarkers.

This evaluates the detection rates of prostate cancer by MRI-targeted prostate biopsy compared to standard 12-core trans-rectal ultrasound guided (TRUS) prostate biopsy. Each participant will be randomly allocated to one of the biopsy tests. We hypothesise that MRI-targeted biopsy will detect no fewer clinically significant cancers than TRUS biopsy but will detect fewer clinically insignificant prostate cancers than TRUS biopsy.

Prostate cancer is the most common cancer in men. Early detection of primary diseases and recurrence is crucial for patient counseling and management. Conventional imaging modalities (CT-MRI) are limited to detect recurrence. Choline-based PET/CT is currently widely used as primary staging tool in prostate cancer and in patients with suspicious recurrent disease. Compared to choline-based tracers, 68Ga-PSMA ligands have been shown to have a higher diagnostic efficacy and to increase the detection of metastases even at low PSA levels. The most widely used prostate-specific membrane antigen (PSMA) ligand is PSMA-11. A supplier, ANMI, has developed a kit formulation of PSMA-11 which will be test in this clinical trial.
