Individual Variations of Taste and Smell Perception in Alcohol Use Disorder (AUD)
NCT05677321 · View on ClinicalTrials.gov ↗
Study Summary
Background: Alcohol use disorder (AUD) is the most common substance use disorder in the world. Long-term AUD can affect a person s sense of taste and smell. This natural history study will compare alcohol drinking behaviors and measures of taste and smell in people with and without AUD. Objective: To understand how alcohol use changes the senses of taste and smell. Eligibility: People aged 18 to 65 years with or without AUD. Design: Participants will be screened. They will have several tests to assess their smell and taste functions. They will answer questions about their eating, alcohol use, and smoking or vaping habits. Participants will have 2 study visits. They will give samples of blood, nasal mucous, saliva, stool, and urine. Their bodies will be measured. They will undergo a type of scan that uses X-rays to measure their body composition. They will complete taste measurements. They will taste liquids by swishing them in their mouth, without swallowing. Then, they will be asked what they can detect and which flavors they preferred. They will also complete smell measurements. They will be asked if they can identify strong odors on a metal wand. They will be asked to rate the intensity and pleasantness of odors. Their brain activity in the frontal regions will be measured while they smell various odors. For this, we will use a brain imaging tool called functional near infrared spectroscopy. They will have sensory testing. Sensations such as pressure, pinpricks, heat, or vibrations will be applied to their skin. Then, they will be asked what they felt. They will keep diaries. They will write down what they eat (for 3 days), the alcohol they drink (3 days), and how much they sleep (14 days). They will wear a wristwatch-like device that records their activity for 14 days.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT05677321
The ClinicalTrials.gov registry entry for NCT05677321 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 475 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: NCT05677321 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.
