Phase 3 Interventional Imperial College London · NCT03069300

This study is testing if adding N-acetylcysteine to standard treatment can help people with severe alcoholic hepatitis lower their risk of infections and improve survival rates.

What this trial studies

This clinical trial investigates the effects of N-acetylcysteine (NAC) on patients with severe alcoholic hepatitis, particularly focusing on its potential to reduce infection rates and mortality. The study is a randomized controlled trial that aims to determine if NAC improves the oxidative burst function of phagocytes, thereby enhancing the immune response in these patients. Participants will receive NAC in addition to standard treatment with prednisolone, and outcomes will be compared to those receiving prednisolone alone. The trial is designed to provide insights into the mechanisms by which NAC may confer protective benefits in this vulnerable population.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with clinical alcoholic hepatitis and specific laboratory criteria indicating severe disease.

Not a fit: Patients who have been abstinent from alcohol for more than six weeks or have other underlying liver diseases will not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly reduce infection rates and mortality in patients suffering from alcoholic hepatitis.

How similar studies have performed: Previous studies have shown promising results with NAC in reducing mortality in similar patient populations, suggesting a potential for success in this trial.
