Study Summary
Background: \- About 17 million adults had an alcohol use disorder in 2012. Researchers want to follow people that have alcohol problems and want treatment, as well as those who do not want treatment and healthy volunteers. They also want to gather information on people with and without alcohol problems, including information on genes and biological processes in the body.. This will help them better understand, prevent, and treat alcohol problems. Objective: -To look at a broad range of traits in people who are healthy people and people with alcohol problems. To study them for potential eligibility for other research protocols conducted at the NIH Clinical Center. Eligibility: * Adults age 18 and older. * Not being pregnant or imprisoned. Design: * Participants will have a physical exam. They will answer questions about their health and alcohol and drug use. They will have an electrocardiogram to check their heart. They will have blood, urine, and breath alcohol tests. * Participants without alcohol problems, or who have them but do not want treatment, can sign the second consent for screening and research. * Participants that have alcohol problems and want treatment will be treated at the NIH Clinical Center. They will be offered to sign the second consent at a later time. * Participants may join an inpatient treatment and detox program. It could last up to 6 weeks. Or they may join an outpatient program. Some may do both. * After discharge, participants may be called and asked questions about their drinking and health. * If participants sign the second consent, they: * will complete paper- and computer-based questionnaires. * will give blood samples. * may have a brain scan using magnetic resonance imaging. They will lie on a table that slides in and out of a cylinder that takes pictures. The machine makes loud noises. They will get earplugs.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT02231840
The ClinicalTrials.gov registry entry for NCT02231840 describes a study currently listed as recruiting. 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 7,500 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 1 condition, with Alcohol Use Disorder 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: NCT02231840 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. Verify current status, eligibility criteria, and contact details directly at ClinicalTrials.gov, and discuss any participation decision with your own healthcare provider.
