About this study

Official title: Effectiveness of High-frequency rTMS in Reducing Alcohol Consumption in Non-abstinent Patients With an Alcohol Use Disorder: A Multicentre Randomised Controlled Study

The fight against alcoholism is a public health priority. Around 15 million Europeans and 10 million North Americans are alcohol dependent. Worldwide, 1 death out of 25 is thought to be attributed to alcohol. In France, the latest published data on alcohol-related mortality indicates that there were 49,000 alcohol-related deaths in 2009. Alcohol is thought to be the leading cause of hospitalisation for French people, and its social cost is estimated at 37.4 billion euros.

However, few patients with an alcohol use disorder are treated: less than 8% in Europe and less than 10.5% in the USA receive appropriate treatment for their alcohol problem. This low rate of treatment is mainly due to the fact that these patients are not ready to stop drinking. They are therefore not attracted by the goal of abstinence that is required by most current therapies and drug treatments. The arrival of new treatments aimed at reducing consumption (rather than abstinence) should make treatment more attractive. To date, nalmefen is the only treatment marketed for this indication. Baclofen should be marketed in 2020, but with restrictive prescription criteria.

In this new strategy to reduce consumption, brain stimulation could play a predominant role as an alternative or complementary therapy. Indeed, functional brain imaging techniques have made it possible to visualise the cortical regions involved in craving, in particular the dorsolateral prefrontal cortex (DLPFC). Craving, i.e. the irrepressible desire to consume, is often at the origin of consumption and relapse. Stimulation of the dorsolateral prefrontal cortex with non-invasive cerebral stimulation techniques, such as repeated transcranial magnetic stimulation (rTMS), has provided encouraging results for the reduction of cravings in all addictive behaviours (alcohol, tobacco, cocaine, food). Furthermore, stimulation of the DLPFC seems to modulate decision-making processes: it may thus reduce impulsivity and strengthen inhibitory control, leading to a reduction in substance use.

The hypothesis to be tested is that repeated transcranial magnetic stimulation allows a reduction in alcohol consumption in patients with an alcohol use disorder.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Active rTMSDevice

    Two rTMS stimulation sessions spaced 15 minutes apart are delivered daily for 5 consecutive days.

    A total of 10 sessions. Stimulation parameters: 10 Hz, 1000 pulses per session, 110% of SM, cortical target: right DLPFC

  • Placebo rTMSDevice

    Two rTMS stimulation sessions spaced 15 minutes apart are delivered daily for 5 consecutive days.

    A total of 10 sessions. Stimulation parameters: delivering a non-significant current at the beginning and end of the stimulation, simulating active stimulation.

  • QuestionnairesOther

    questionnaires for craving assessment: EVA, OCDS, CGI and ADS and signs of physical withdrawal by CIWA

  • BreathalyzerDevice

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. total alcohol consumption (g/d)

    total alcohol consumption (g/d), measured by average daily consumption

    Measured: through study completion, an average of 1 month

  2. number of days of high consumption

    reduction in the number of days of high consumption (≥ 60 g/d for men, ≥ 40 g/d for women)

    Measured: through study completion, an average of 1 month

Questions about this trial

What is this clinical trial studying?

A study testing Active rTMS, Questionnaires and Breathalyzer in people with Alcoholism and rTMS Stimulation, run by Centre Hospitalier Universitaire Dijon at 1 site in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 24 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 17 Apr 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

total alcohol consumption (g/d) (time frame: through study completion, an average of 1 month). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04773691, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Apr 2025.
