Phase 1 Interventional National Institutes of Health Clinical Center (CC) · NCT04781322

This study is testing if the drug alirocumab is safe for heavy drinkers aged 21 to 65 and if it can help improve their liver health.

What this trial studies

This study investigates the safety and tolerability of alirocumab, a PCSK9 inhibitor, in non-treatment seeking heavy drinkers aged 21 to 65 who consume an average of 20 or more alcoholic drinks per week. Participants will receive either alirocumab or a placebo via injection and undergo various assessments including blood and urine tests, physical exams, and imaging studies to evaluate liver function and inflammation. The primary goal is to determine the incidence of adverse events, while secondary objectives will explore changes in biomarkers related to liver damage and inflammation.

Who should consider this trial

Good fit: Ideal candidates are healthy adults aged 21 to 65 who are non-treatment seeking heavy drinkers consuming 20 or more drinks per week.

Not a fit: Patients seeking treatment for alcohol use disorder may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a novel treatment option for individuals with alcohol-associated liver disease.

How similar studies have performed: While the approach of using alirocumab in this context is novel, previous studies have shown its potential to reduce liver damage in animal models.
