Using Belimumab to treat Autoimmune Hepatitis

Belimumab in the Management of Autoimmune Hepatitis: A Multi-centre, Open-label Trial of add-on Belimumab Therapy to Standard of Care

Phase 2 Interventional University Health Network, Toronto · NCT06381453

This study is testing if Belimumab can help people with autoimmune hepatitis feel better and improve their liver function when other treatments haven't worked.

What this trial studies

This clinical trial investigates the efficacy of Belimumab, an auto-injector medication, in treating patients with autoimmune hepatitis (AIH). The study aims to assess the impact of this targeted therapy on liver function and overall patient quality of life, particularly for those who have not responded well to existing treatments. Participants will be divided into two groups based on their liver enzyme levels and current immunosuppressive therapy. The trial will follow an open-label design, allowing for real-time assessment of treatment effects.

Who should consider this trial

Good fit: Ideal candidates include individuals with a confirmed diagnosis of autoimmune hepatitis who have been on stable immunosuppressive therapy for at least four weeks.

Not a fit: Patients with primary liver diseases other than autoimmune hepatitis or those with high probability of alternative etiologies may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a more effective and targeted therapy option for patients suffering from autoimmune hepatitis.

How similar studies have performed: Other studies have shown promise in targeting B-cells for autoimmune conditions, suggesting potential for success with this approach in autoimmune hepatitis.
