PET Imaging of Cyclooxygenases in Neurodegenerative Brain Disease
NCT04396873 · View on ClinicalTrials.gov ↗
Study Summary
Background: About 5 million adults in the U.S. have Alzheimer s disease or another adult-onset neurodegenerative disorder. Many studies have found that inflammation in the brain contributes to these diseases. Researchers want to find a better way to measure this inflammation. Objective: To learn whether COX-1 and/or COX-2 is elevated in the brains of individuals with neurodegenerative brain disease compared to healthy volunteers. Eligibility: Adults age 18 years and older in good general health who have an adult-onset neurodegenerative dementia, such as AD, FTD, corticobasal syndrome, Huntington s disease, or MCI, ALS and healthy adult volunteers enrolled in protocols 01-M-0254 or 17-M-0181. Design: Participants will be screened with medical history, physical exam with vital signs, and lab tests. They will have a neuropsychological testing. Their heart function will be measured. Participants will have a magnetic resonance imaging (MRI) scan. The MRI scanner is a metal tube surrounded by a strong magnetic field. Participants will lie on a table that slides in and out of the tube. The machine makes noise. Participants will get earplugs. Participants will have 2 PET scans. They will be injected with the study drugs through an intravenous catheter placed in an arm vein. The PET scanner is shaped like a doughnut. Participants will lie on a bed that slides in and out of the scanner. A plastic mask will be molded to their head to keep them from moving. A thin plastic tube will be put into an artery at the wrist or elbow crease area. This will be used to draw blood during the scan. Participants will have 2-5 study visits. Participation lasts 1 week to 4 months, depending on scheduling.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT04396873
The ClinicalTrials.gov registry entry for NCT04396873 describes a study currently listed as recruiting. It is categorized as Phase 1, 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 184 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is National Institute of Mental Health (NIMH), which has 317 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 5 conditions, with Mild Cognitive Impairment appearing as the primary indexed condition, and to 3 interventions — of which 11C-MC1 is the first listed. 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: NCT04396873 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.
