Ketamine-assisted psychological therapy to reduce alcohol relapse

Medical Conditions

Severe alcohol use disorder


This information is provided directly by researchers and we recognise that it isn't always easy to understand. We are working with researchers to improve the accessibility of this information.


In the UK more than half a million adults have alcohol problems. Only 1 in 5 people with alcohol problems get treatment. Even of those who quit alcohol, 3 out of 4 will be back drinking heavily after a year. Alcohol-related harm is estimated to cost the UK NHS around £3.5 billion each year and wider UK society around £40 billion. Alcohol problems affect not only the individual but families, friends and communities. Alcohol-related deaths have increased still further since the pandemic and we urgently need new treatments. We previously ran a small phase II clinical trial in 96 people with severe alcohol problems. The treatment was 3 doses of ketamine given through a drip combined with 7 sessions of psychological therapy (KARE therapy). We found KARE therapy could reduce drinking 6 months after the start of treatment when compared to placebo. The study also found that giving psychological therapy combined with ketamine reduced drinking still further than when ketamine was given without psychological therapy. This phase III, multi-site study will build on our phase II trial and will run in up to 10 NHS sites across the UK.

Start dates may differ between countries and research sites. The research team are responsible for keeping the information up-to-date.  

The recruitment start and end dates are as follows:

25 Jun 2024 31 Dec 2025

We will randomise 280 participants to receive 3 intravenous infusions of either a therapeutic or subtherapeutic dose of ketamine at weekly intervals. Participants will also be randomly allocated to receive either 7 sessions of psychological therapy or an alcohol education package. There will be 10 appointments over 6 months. At these visits medical assessments will be carried out including blood and urine samples analysis and psychological questionnaires will look at alcohol usage and mental health in the trial. We hope to collect enough evidence to establish if this treatment works, so that it may begin to be used in NHS settings.


Adults with severe alcohol use disorder (AUD).

History of ketamine use disorder as assessed by the SCID.5. Pregnant or breast-feeding6. Not willing to use effective contraception or (people of child-bearing potential) take pregnancy test.7. Use of another experimental IMP that is likely to interfere with the trial medication within 3 months of trial enrolment.8. Known allergies to ketamine or excipients of IMP.9.

Received any previous ketamine treatment.

We hope participating in the trial would help participants with their own aims to reduce or quit drinking alcohol. Participants are also offered the opportunity to wear an alcohol monitoring device which has been shown to help people stay abstinent from alcohol. Participants are also offered psychological support which can help participants reduce their drinking or remain sober. Taking part can also lead to indirect benefits, leading to improvements in future understanding and treatment of alcohol use disorders, and help people remain abstinent for longer.
Ketamine is a safe and well-tolerated drug. However like all drugs, ketamine can cause effects on the body; most of these are mild and resolve quickly after the infusion of the drug is finished. In this trial we are using lower doses of ketamine than those used in anaesthesia. Ketamine has different effects on different people, however common side effects at this dose (affecting 1 in 10 people) are likely to include dissociative effects which may feel strange, like you are outside of your body, or have strange changes to hearing or vision. Some people can feel nauseous or be sick when they receive ketamine and their breathing, blood pressure and heart rate can quicken. Participants may also experience a mild rash or redness of the skin following infusion, which will resolve after the infusion stops. Participants are closely monitored throughout and after each infusion to check for any side effects. The effects are anticipated to only last for a short time and to wear off quickly after the infusion is stopped.
