What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused

Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Summary

This study explores how alcohol affects the gut microbiome and whether personalized prebiotics can help restore balance. Researchers will test a new tool (DynaMAP) to map gut bacteria in 20 healthy adults who drink moderately. Participants take a daily prebiotic for 60 days, and the study measures changes in gut bacteria, brain function, and overall health.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 20 people

The number the study aims to enrol. It can still change while the study runs.

Started

Dec 2025

Expected to finish

Jun 2026

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Healthy volunteers

Accepted

You do not need to have the condition being studied to take part.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion criteria: * Adults aged approximately 18-65 years * Male or female * Generally in good health, with no significant chronic illnesses * Resident in the UK (to enable centralized ethics oversight and logistics) * Able to re and understand English (for e-consent and study instructions) * Mild to moderate alcohol consumption (more than 14 units or 6 pints per week) * Willing to provide stool samples at the required time points * Willing to take a daily prebiotic supplement for 60 days * Has access to the internet and email for remote communication * Able and willing to provide informed electronic consent Exclusion criteria: * Any known significant gastrointestinal disease (e.g., inflammatory bowel disease, celiac disease) * Any major medical condition that could affect the gut microbiome or pose a health risk (e.g., immunocompromised conditions) * Recent use of antibiotics (within the past 2-3 months) * Recent regular use of probiotics or prebiotics (within approximately the past 4 weeks) * Pregnant or breastfeeding women (pregnancy will be screened at enrolment, as the intervention is not tested during pregnancy and pregnancy itself alters the gut microbiome) * Known allergies or intolerances to components likely used in the prebiotic formulation (e.g., certain amino acids) * Use of special diets or medications that significantly alter gut microbiota (e.g., chronic laxative use, immunosuppressive therapy) * Participation in another interventional clinical trial within the past 3 months
