Filter by:The purpose of this study is to evaluate the effects of multiple doses of abiraterone acetate plus prednisone on the pharmacokinetics (study of what the body does to a drug) of single doses of dextromethorphan hydrobromide and theophylline in patients with castration resistant prostate cancer.
RATIONALE: Gathering information about genetic and environmental factors may help doctors learn more about a person's risk for developing prostate cancer. PURPOSE: This research project is studying genes, environment, and prostate cancer risk in patients with or without prostate cancer.
The main study objective was to collect implant retrieval information in 10 patients using Vantas®, the 50 mg histrelin implant. Patients who had been identified as having a difficult to locate or non-palpable implant were to have been enrolled. Sites were to adhere to the instructions in the Package Insert, which included specialized investigations such as ultrasound, CT, and MRI, to be used for the location and removal of implants.
RATIONALE : Drugs used in chemotherapy, such as docetaxel, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Dietary supplements, such as phytochemicals, may stop or delay the development of prostate cancer.
The purpose of this study is to compare the efficacy of three drugs (cyproterone acetate, medroxyprogesterone acetate and venlafaxine) in the treatment of hot flushes caused by leuprorelin LP 11.25 milligram (mg) in participants suffering from prostate cancer.
RATIONALE: Tomato-soy juice may slow the growth of tumor cells. Studying samples of blood and tissue from patients with prostate cancer in the laboratory may help doctors identify biomarkers related to cancer. It may also help doctors understand the effect of tomato-soy juice on biomarkers. PURPOSE: This phase I/II trial is studying the side effects of tomato-soy juice and its effect on biomarkers in patients with prostate cancer undergoing prostatectomy.
The purpose of this study is to develop a practice procedure for lymphatic drainage mapping with the intent of providing a new tool that could potentially be used for radiation treatment planning. High-risk prostate cancer patients who are scheduled to be treated with intensity-modulated radiotherapy (IMRT) may be eligible to enroll in this study. 99mTc-sulfur nanocolloid, a radiopharmaceutical ("tracer") will be injected by a urologist using transrectal ultrasound guidance (TRUS)at the UCSF Urology Clinic. Participants will then undergo SPECT/CT imaging at the UCSF Nuclear Medicine Clinic. This study will evaluate the feasibility of transporting patients to the Nuclear Medicine Clinic for imaging within 1-3 hours after administration of 99mTc-sulfur nanocolloid.
Less than 20% of men in whom prostate cancer is diagnosed early die from it. Cardiovascular disease is the most common cause of death in men with early prostate cancer. A commonly used form of treatment for prostate cancer is androgen deprivation therapy (ADT). ADT, while effective for the treatment of prostate cancer, has been linked to undesirable side effects, such as an increased risk of bone fractures and diabetes. Bisphosphonates, a class of drugs that prevent bone resorption, have been show to reduce the loss of bone mineral density that occurs as a consequence of ADT, but the effects of bisphosphonates on preservation of bone architecture is unknown. This project has two main goals: To assess prospectively, in men with prostate cancer receiving ADT, the effect of: 1. the intravenous bisphosphonate zoledronic acidon ADT-induced microarchitectural decay of bone structure. 2. ADT on insulin resistance and glucose metabolism. We will recruit 100 ambulatory men with non-metastatic prostate cancer who are about to commence a three year course of ADT as per routine clinical practice at Austin Health. Men will be randomised to receive either intravenous zoledronic acid (Aclasta, Novartis Pharmaceuticals) or placebo at baseline and after 12 months of ADT. Men with contraindications to zoledronic acid will be excluded from the study. All 100 study subjects will have clinical and laboratory assessment at baseline, and at 3, 6, 12, 18 and 24 months (study end), and imaging studies at baseline and at 6, 12 and 24 months. The study protocol is outlined in more detail below (Please see flow chart included in the in PICF): Clinical and laboratory assessment: Full medical history, physical examination and quality of life assessment using the SF-36 questionnaire. Laboratory studies will include: oral glucose tolerance test (3, 12 and 24 months Commercial-in-Confidence only) and measurements of measure total testosterone, fasting glucose, C-peptide, HBA1c, bone turnover markers. Imaging studies: 1. Bony micro-architecture by high resolution quantitative computed tomography 2. Bone mineral density and body composition by DEXA This project will have no direct benefit for the subjects involved in this study; however, it will improve our understanding on the effect of zoledronic acid on bone microarchitecture in men with prostate cancer receiving ADT. It will also help us to better understand the effect of ADT on insulin resistance and glucose metabolism.
The objective of this study is to obtain blood samples, solid tumor and/or benign hyperplasia samples to learn more about genetic differences that are linked to the formation of solid tumors.
This is an open-label study comparing the imaging characteristics of 123-I-MIP-1072 and ProstaScint® (111-In-capromab pendetide)in patients with metastatic prostate cancer. Eligible patients will receive a dose of 123-I-MIP-1072 and have imaging studies and safety assessments (physical examination, vital signs, electrocardiogram, clinical laboratory tests) performed during the subsequent 24 hours. Two weeks later, patients will return for additional safety assessments and will receive ProstaScint® if they don't already have a pre-existing ProstaScint scan. Final assessments will be performed two weeks after the ProstaScint® scan unless there is a difference between the 123-I-MIP-1072 and ProstaScint® scans. If this is the case, another dose of 123-I-MIP-1072 will be given 12 weeks later, and imaging studies repeated.
