Brain Response to Pain Control in People With Chronic Pain
NCT01878019 · View on ClinicalTrials.gov ↗
Study Summary
Background: \- Researchers want to look at how the brain responds to painful stimulations. They also want to see if these responses are different in people with and without chronic pain. To test the brain s response, they will use a chemical called naloxone. Naloxone is used to treat overdoses of painkilling drugs like morphine. It may be able to block the effect of a pain-relieving cream. Researchers will apply a pain-relieving cream to a person s lower leg and look at the results of sensitivity tests with either naloxone or a placebo. This study will compare the results from people with chronic pain (like fibromyalgia) to those of people without chronic pain. Objectives: \- To look at the brain s response to pain in people with and without chronic pain. Eligibility: * Individuals at least 18 years of age who have fibromyalgia. * Healthy volunteers at least 18 years of age. Design: * This study will involve a screening visit and two testing visits. The testing visits will be about a week apart. * Participants will be screened with a physical exam and medical history. Blood and urine samples will be collected. After the screening participants will be administered several questionnaires about their personality, and their thoughts and feelings. * At the first visit, participants will try out the magnetic resonance imaging (MRI) scan before using it at the next visit. They will then have the painkilling cream applied on one part of their lower leg and a normal moisturizing cream on the other part of their lower leg. They will have heat pulses on these skin areas and rate the pain. * At the second visit, participants will have tests in the MRI scanner. The heat pulse tests will be repeated after an infusion of either naloxone or a placebo.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT01878019
The ClinicalTrials.gov registry entry for NCT01878019 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 92 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is National Center for Complementary and Integrative Health (NCCIH), which has 55 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 Pain 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: NCT01878019 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.
