Filter by:The purpose of this study is to evaluate clinical safety and efficacy of a gastric ulcer drug, polaprezinc (POL), with the AR-inhibitor abiraterone in Chinese patients with castration-resistant prostate cancer (CRPC).
This phase III study provides access to 68Ga-PSMA-11 positron emission tomography (PET)/computed tomography (CT) imaging for patients with castrate-resistant prostate cancer that has spread to other places in the body (metastatic) being considered for177Lu-PSMA-617 therapy. T PET is an established imaging technique that utilizes small amounts of radioactivity attached to very minimal amounts of this tracer. CT utilizes x-rays that traverse body from the outside. CT images provide an exact outline of organs and potential inflammatory tissue where it occurs in patient's body. Combining a PET scan with a CT scan can help make the images easier to interpret. The 68Ga-PSMA-11 PET/CT scan is done with a very small amount of radioactive tracer call 68- gallium PSMA-11. In patients that have been diagnosed with prostate cancer, a protein called prostate-specific membrane antigen (PSMA) appears in large amounts on the surface of the cancerous cells. The radioactive imaging agent (68Ga-PSMA-11) has been designed to circulate through the body and attach itself to the PSMA protein on prostate cancer cells. A PET/CT scan is then used to detect the location of prostate cancer lesions. By gaining access to 68Ga-PSMA-11 PET/CT scans, patients may be safely screened for 177Lu-PSMA-617 therapy in the treatment of metastatic castrate resistant prostate cancer.
The purpose of this study is to evaluate a radioactive diagnostic study drug, which is called Gallium-68 Prostate Specific Membrane Antigen ([Ga-68]PSMA) for detection of bone metastasis in patients with prostate cancer. For imaging the investigators will use a FDA approved imaging technology, digital Positron Emission Tomography (PET/CT). The investigators would like to know if digital PET/CT using [Ga-68]PSMA provides accurate information about the extent of bone metastases. Therefore, the investigators will compare[Ga-68]PSMA PET/CT with Flourine-18 [F-18] Sodium Fluoride (NaF), which is a high resolution bone scan. [F-18]NaF is FDA approved and the reference standard for evaluating the presence of bone metastases.[Ga-68]PSMA is an investigational (experimental) drug that works by binding to Prostate Specific Membrane Antigen, which is overexpressed in prostate cancer. [Ga-68]PSMA is experimental because it is not approved by the Food and Drug Administration (FDA) at University Hospitals. However, FDA approval has been obtained for this study protocol by an Investigational New Drug (IND) application.
This is a national-level research study of urologists. The purpose of this study is to assess the clinical evaluation and management (drug, procedures, counseling and other) of a subset of common patient care indications.
This study will be a retrospective data analysis to compare outcomes between patients with chemotherapy-naïve metastatic castration-resistant prostate cancer (mCRPC) who initiated enzalutamide and those who initiated abiraterone using the 100% Fee-For-Service Medicare claims data. The study will address the following objectives: Primary objective: To compare overall survival (OS) in patients with chemotherapy-naïve mCRPC who initiated enzalutamide vs. abiraterone Secondary objectives: - To compare OS in patients with chemotherapy-naïve mCRPC who received only enzalutamide without any subsequent therapy vs. abiraterone without any subsequent therapy - To compare treatment duration and time to subsequent therapy in chemotherapy-naïve mCRPC patients initiating enzalutamide vs. abiraterone
The hepatic enzyme, cytochrome P450 3A4 (CYP3A4) is important for the metabolism of many drugs including taxanes. Previous reported studies reported a decreases in docetaxel exposure in prostate cancer patients compared to patients with other solid tumours. The difference was 1.8-fold for intravenous administration and 2.8-fold for oral administration. The underlying mechanism for these observations remains to be elucidated. The lower docetaxel exposure with IV and oral docetaxel treatment might be related to a higher CYP3A4 activity in prostate cancer patients. Therefore, it is important to directly compare the CYP3A4 activity with a phenotyping test in prostate cancer patients and patients with other types of solid tumours. This is an in vivo phenotyping studying using midazolam as a probe for CYP3A4 activity in patients with prostate cancer and patients with other solid tumours. The primary objective is the comparison of CYP3A4 activity in prostate cancer patients versus male patients with other types of solid tumours by use of an oral midazolam phenotyping test. Secondary objectives are: (1) measurement of plasma concentrations of midazolam and it's two primary metabolites (1'-hydroxy midazolam and 4'-hydroxy midazolam), (2) determination of the metabolite pharmacokinetics of midazolam. (3) retrospective assessment of single nucleotide polymorphisms of CYP3A4. The exploratory objective is to differentiate between gastro-intestinal and hepatic CYP3A4 activity with oral and intravenous administration of midazolam.
This study evaluates the diagnostic performance and safety of 18F-Thretide PET/CT in patients with biopsy proven prostate cancer who has no any form of therapy against prostate caner or suspected recurrence of prostate cancer who have negative or equivocal findings on conventional imaging.
The seven sweeps is a recommended act performed by men after urinating in order to be confident that no urine is left in the urethra, and its not compulsory to perform. It is performed by the following way: after urinating, the anus is first purified if it has become impure; then, the middle finger of the left hand is slid three times from the anus up to the scrotum; then, the thumb is placed on the penis and the forefinger is placed under the penis, and the thumb and forefinger are pulled three times along the penis up to the point of circumcision; finally, the end of the penis is pressed three times.
The PI-CAI challenge aims to validate the diagnostic performance of artificial intelligence (AI) and radiologists at clinically significant prostate cancer (csPCa) detection/diagnosis in MRI, with respect to histopathology and follow-up (≥ 3 years) as reference. The study hypothesizes that state-of-the-art AI algorithms, trained using thousands of patient exams, are non-inferior to radiologists reading bpMRI. As secondary end-points, it investigates the optimal AI model for csPCa detection/diagnosis, and the effects of dynamic contrast-enhanced imaging and reader experience on diagnostic accuracy and inter-reader variability.
The purpose of this study is to test a stress management program for men with early-stage prostate cancer.
