Brief Summary:

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 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.

Drug Information available for: Alirocumab

Arm Intervention/treatment
Experimental: Intervention
Heavy drinking healthy volunteers
Drug: Alirocumab
Alirocumab is a human monoclonal antibody (IgG1) that binds to and inhibits PCSK9 and was approved by the FDA in July of 2015. PCSK9 binds to and promotes degradation of low-density lipoprotein receptors (LDLR) on hepatocyte membranes.

Placebo Comparator: Placebo
Heavy drinking healthy volunteers
Other: Placebo
Heavy drinking healthy volunteers




Primary Outcome Measures :
  1. The primary objective is to assess the safety and tolerability of alirocumab in subjects who are heavy drinkers. [ Time Frame: 8 weeks ]
    The primary endpoint in the study is to assess the incidence and severity of treatment-emergent adverse events in non-treatment seeking heavy drinkers treated with alirocumab or placebo.


Secondary Outcome Measures :
  1. Secondary/exploratory objectives are to assess various biomarkers related to alcohol-induced liver damage and inflammation. [ Time Frame: ongoing ]
    These biomarkers will assess various biological processed in AUD, such as inflammation, liver biology and clinical alcohol-related outcomes.
