Is this trial a fit for you?

Likely a good fit

Adults (18+) with severe alcohol-associated hepatitis (Maddrey’s DF ≥ 32), without ACLF, who use alcohol at high levels and are not in the ICU.

Probably not a fit

Patients with advanced organ failure or ACLF, those in the ICU, or those with contraindications to A1AT may not benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a phase 2, open-label pilot trial conducted at a single center. Participants with severe alcohol-associated hepatitis will receive Alpha-1 Antitrypsin to see if it lowers systemic inflammation and affects clinical outcomes. Safety and adverse events will be tracked alongside changes in inflammatory cytokines. The study aims to provide preliminary data on whether A1AT is beneficial in this patient population. Results could guide larger future studies if signals of benefit emerge.

Why it matters

Potential benefit: If successful, A1AT could reduce inflammation and improve short-term outcomes in patients with severe AAH.

How similar studies have gone: Prior preclinical data and observational findings suggested anti-inflammatory effects of A1AT and potential associations with outcomes in liver disease; this trial tests those concepts prospectively.
