Effect of LY686017 on Alcohol Craving
NCT00310427 · View on ClinicalTrials.gov ↗
Study Summary
This study will determine whether the experimental drug LY686017 can reduce a person's desire for alcohol. A brain chemical called Substance P acts at places in the brain called NK1 receptors. Substance P is released in response to stress and gives rise to behaviors that are thought to represent anxiety. LY686017 blocks Substance P from acting at the NK1 receptors. People between 21 and 65 years of age who have been drinking on a regular basis for at least one month before entering the study, who meet the criteria for alcohol dependence and who have an elevated score on a general test of anxiety may be eligible for this study. Participants are admitted to the NIH Clinical Center for 35 days. They participate in an alcohol treatment program in addition to the research study. After having been withdrawn from alcohol for at least 2 days, participants receive either 50 mg of LY686017 or placebo (an inactive substance that looks like the study drug) every morning for 28 days. In addition to drug treatment, they undergo the following procedures: * Functional magnetic resonance imaging (fMRI): In the last week of the study, subjects undergo MRI to study the amount of blood going to brain structures thought to be involved in anxiety and craving. During the procedure, they look at pictures of faces exhibiting various emotions and pictures related to alcohol. * Cue reactivity: At the beginning and towards the end of the study, subjects are asked to rate their alcohol craving and their anxiety level while they sniff and handle their favorite alcoholic beverage or water. * Metyrapone test: During weeks 1 and 4 of the study, subjects are given metyrapone - a drug that interferes with the body's ability to make the stress hormone cortisol - to determine how LY686017 affects the body's hormonal response. The drop in cortisol from metyrapone administration causes the brain to release ACTH, a hormone that causes the adrenal gland to make cortisol. * Trier test: In the last week o

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00310427
The ClinicalTrials.gov registry entry for NCT00310427 describes a study currently listed as completed. It is categorized as Phase 2, 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 66 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is National Institute on Alcohol Abuse and Alcoholism (NIAAA), which has 118 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 Alcoholism appearing as the primary indexed condition, and to 2 interventions — of which Placebo 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: NCT00310427 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.
