PET Evaluation of Brain Peripheral Benzodiazepine Receptors Using [11C]PBR28 in Frontotemporal Dementia
NCT00613119 · View on ClinicalTrials.gov ↗
Study Summary
This study will use positron emission tomography (PET) imaging to measure a receptor in the brain that is involved in inflammation. Certain neurological disorders, possibly including frontotemporal dementia (FTD), are associated with increased inflammation in the brain. This study may help elucidate the relationship between FTD and inflammation. Patients with FTD and healthy volunteers who are 35 years of age or older may be eligible for this study. Candidates are screened with a medical history, physical examination, electrocardiogram, and blood and urine tests. Participants undergo the following procedures: * Whole body PET scan: PET uses small amounts of a radioactive chemical called a tracer that labels active areas of the brain so the activity can be seen with a special camera. The tracer used in this study is \[11C\]PBR28. Before starting the scan, a catheter (plastic tube) is placed in a vein in the arm to inject the tracer. Pictures are taken for 1 hour. This short scan is done to determine if \[11C\]PBR28 binds to the subject s receptors, since a number of people do not have binding. Subjects who have binding continue with brain PET and MRI scans, described below. * Brain PET imaging: Before starting the scan, a catheter is placed in a vein in the arm to inject the tracer,\<TAB\> and another catheter is placed in an artery in the wrist to obtain blood samples during the scan. The subject lies on the scanner bed. A special mask is fitted to the head and attached to the bed to help keep the person s head still during the scan so the images will be clear. An 8-minute transmission scan is done just before the tracer is injected to provide measures of the brain that are helpful in calculating information from subsequent scans. After the tracer is injected, pictures are taken for about 2.5 hours, while the subject lies still on the scanner bed. * Blood and urine tests are done the day of and the day following each PET scan. * Magnetic resonance imaging (MRI):

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00613119
The ClinicalTrials.gov registry entry for NCT00613119 describes a study currently listed as completed. 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 108 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 2 conditions, with Dementia 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: NCT00613119 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.
