Placebo Impacts Sleep and Pain Modulation in Chronic Pain
NCT06225817 · View on ClinicalTrials.gov ↗
Study Summary
The goal of this free-choice parallel design clinical trial is to examine the potential beneficial effects of using open-label placebo (OLP) in improving chronic pain related outcomes and sleep quality in people with temporomandibular disorders. This study will enroll a cohort of participants with temporomandibular disorders (TMD) which lasts for more than 3 months. The main questions it aims to answer are: 1. Will participants with TMD be more likely to take open-label placebo pills if they are introduced to the effects of placebo (e.g., going through an expectation management session)? 2. Will taking open-label placebo plus expectation management improve chronic pain related outcomes, such as chronic pain intensity, interference, levels of anxiety and depression, in the cohort of TMD? 3. Will open-label placebo plus expectation management improve sleep quality in participants suffering from TMD? To answer the above questions, participants with TMD will be randomly assigned to three groups: 1. Open-label placebo plus expectation management group, where participants will complete a 1-hour discussion session about their expectations toward open-lable placebo intervention, and then take 1 open-labe placebo pill per day for a total of 45 days. 2. Open-label placebo only group where participants will be asked to take open-label placebo pills, one pill per day, for a total of 45 days. 3. standard of care group where participants will maintain their usual care without introducing open-label placebo to them during the 45 days monitoring. Researchers will compare the chronic pain intensity, interference, mood, anxiety, and sleep quality between the open-label placebo group and the wait-list group. Daily chronic pain will be measured using visual analog scale (VAS) ranging from 0=no pain at all to 100=maximum tolerable pain. Chronic pain interference using Patient-Reported Outcomes Measurement Information System (PROMIS) pain interference and pain behavior. Anxiety and dep

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT06225817
The ClinicalTrials.gov registry entry for NCT06225817 describes a study currently listed as recruiting. It is categorized as NA, 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 111 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is University of Maryland, Baltimore, which has 559 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 Chronic Pain appearing as the primary indexed condition, and to 1 intervention — of which Open-label placebo pills 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: NCT06225817 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.
