Evaluation of Atherosclerotic Plaques in Abdominal CT Studies
NCT04652973 · View on ClinicalTrials.gov ↗
Study Summary
Background: Fat and calcium can build up as plaque in artery walls. The Agatston score measures plaque using computed tomography (CT) that does not use an injected contrast agent. Plaque in the arteries of the pelvis and abdomen is linked to cardiovascular disease (CVD) risk factors. It also may affect cancer. But abdominal CTs use a contrast agent (CECT). Therefore, the Agatston score cannot be used. Researchers want to find a way to measure plaque in CECTs. This will help them use abdominal CTs to measure plaque without extra radiation. Objective: To measure atherosclerotic plaques on CECT in a group of males. Eligibility: Men ages 30-90 with prostate cancer (proven with biopsies) who have abdomen CT studies in the PACS (picture archiving system) in the Clinical Center. Also, men or women of all ages who have multiphase abdomen and pelvic CT studies that are in the PACS. Design: This study will use data gathered since 1/1/2013. Data will also be taken from protocol 03-CC-0128 and clinical trials 15-C-0124, 16-C-0048, 14-C-0112, and 04-C-0274. Participants from these studies have allowed their samples to be used in the future. Participants will be found via keyword searches on NIH databases. Their CT and MRI scans will be used. Data such as age, race, disease, and treatment will be used. Results of other tests may be used. The plaque in participants abdomen and iliac arteries will be measured. It will be compared with biomarkers related to CVD and prostate cancer, such as weight, age, and race. This study will take place at one site. Data will be stored on secure computers. Printouts will be kept in locked rooms.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT04652973
The ClinicalTrials.gov registry entry for NCT04652973 describes a study currently listed as active not recruiting. It is categorized as an unspecified phase, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 118 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is National Institutes of Health Clinical Center (CC), which has 209 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Prostatic Neoplasms appearing as the primary indexed condition, and to 0 interventions. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT04652973 reports 1 study location spanning 1 distinct geographic area — top geographies include Maryland. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
