Safety, Tolerability, and Bioeffects of Alirocumab in Non-treatment Seeking Heavy Drinkers

Background: Drinking alcohol can lead to swelling and injury in the liver. Long-term heavy drinking may lead to liver disease. Researchers want to study the relationship between a drug called alirocumab, alcohol use, and liver functioning/swelling. Objective: To study the effects of alirocumab in people who drink alcohol. Eligibility: Healthy adults ages 21 to 65 who regularly consume an average of 20 or more drinks per week. Design: Participants will be screened under protocol 14-AA-0181. Participants will get alirocumab or a placebo as an injection under the skin. Participants will give blood and urine samples. They will have physical exams. Participants will have FibroScans . It measures liver and spleen stiffness. Participants will lie on a table. They will expose the lower right and left side of their chest. The machine will send a small vibration to the liver. Participants may have magnetic resonance imaging (MRI) scans of the liver. The MRI scanner is shaped like a cylinder. Participants will lie on a table that slides in and out of the scanner. A device called a coil will be placed over their liver. Participants will have a Doppler scan and ultrasound. These tests measure blood flow in the body. Participants will have an electrocardiogram. It measures heart function. Participants will fill out surveys about how they are feeling, their alcohol consumption, and other behaviors. They will complete cognitive tasks on a computer. Participants will meet with a clinician. They will discuss the participant s assessment results, patterns of drinking, and possibly stopping or cutting down on drinking. Participation will last for 8 weeks. Participants will have 9 study visits.

ADDICTOlogical Intervention in LIVEr Transplantation Recipients

Transplantation for end-stage-liver disease (ESLD) in the context of Alcohol-Associated Liver Disease (AALD) has been increasing and represents the main indication for Liver Transplantation (LT) in the world. Alcohol Use Disorder (AUD) is considered a brain chronic disease and requires a transdisciplinary approach that includes medical treatment and behavioral interventions. In the context of LT, alcohol relapse occurs in 26 % up to 50% of LT recipients. Among Liver transplant recipients for AALD, severe alcoholic relapse (defined as more than 3 alcoholic drinks per day for women and 4/day for men) after LT leads to impaired longterm survival due to recurrent alcoholic cirrhosis (RAC), cardiovascular events and de novo cancer. Several strategies have been developed to prevent alcohol relapse. After LT, integrating an addiction team into the LT program has been advocated by the latest guidelines in Europe and the United States, in order to bring the management of alcohol-use disorder (AUD) in transplantation units, through the association of psychosocial and pharmacological interventions previously reported in AALD. However, those guidelines were based on descriptive studies, and the effect of this management needs to be confirmed through a randomized, controlled, multicenter study, involving centers that still do not include an addiction team in their LT programs. This study will therefore assess prospectively and comparatively the impact of an addiction intervention after LT on return to alcohol use rates. We hypothesize that standardized targeted addiction monitoring of Liver Transplant recipients decreases the rates of alcohol relapse two years post-liver transplantation.
