NAlmefene Versus Placebo in Addition to Treatment as Usual on Craving in Behavioural Addictions

To be considered for this study, you need to be at least 18 years old. You must have been diagnosed with either a gambling disorder, food addiction, or sexual addiction, and be receiving or starting care for this condition in an addiction treatment centre. You’ll also need to be able to keep a weekly record of your cravings.

There are also some requirements for women who could become pregnant. They would need to be using reliable birth control, or have gone through menopause, or have had certain surgical procedures. All participants must provide written permission to take part, and be part of the French social security system.

However, you can't join if you’re already taking other medications specifically aimed at reducing cravings for behavioural addictions (like naltrexone or bupropion, among others). Also, if you have any health condition that would make it unsafe for you to take Nalmefene, you would not be able to participate.

The detailed information on participation, including the number of visits, assessments, medication schedule, follow-up, and total duration, is not provided in the brief or detailed description. Generally, in a Phase 3 trial like this, you would likely have regular clinic visits, receive either the study drug (Nalmefene) or a placebo (a dummy pill), and be asked to keep a diary of your cravings. You might also have blood tests and other health checks. The study would likely last several weeks or months. Full details would be explained by the study team.
