Clinical trial Recruiting at 14 sites Phase 2 Interventional Ages 18 to 60

Evaluating a new combination therapy for chronic Hepatitis B infection

Official title: A Phase 2 Multicenter, Randomized, Double-Blind Study to Evaluate the Efficacy and Safety of Combination Therapy of BRII-179, BRII-835 and Pegylated Interferon Alpha (PEG-IFNα) in Participants With Chronic Hepatitis B Virus (HBV) Infection (ENHANCE)

Run by Brii Biosciences Limited · NCT06650852 · Data updated 2026-11-12

This study is testing a new combination treatment for adults with chronic Hepatitis B who are already on medication to see if it works better than the standard treatment alone.

Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are adults aged 18-60 with chronic HBV infection who have been on NRTI therapy for at least 6 months.

Probably not a fit

Patients with significant liver fibrosis, cirrhosis, or other chronic liver diseases may not benefit from this study.

What this trial studies

This Phase 2, randomized, double-blind study aims to assess the efficacy and safety of a combination therapy involving BRII-179, BRII-835, and PEG-IFNα in adults with chronic Hepatitis B virus (HBV) infection who are already on nucleos(t)ide reverse transcriptase inhibitors (NRTIs). Participants will be compared to a control group receiving PEG-IFNα alone. The study focuses on individuals without cirrhosis and evaluates the treatment's impact on HBV infection over time. The trial will involve multiple investigative sites in Beijing.

Why it matters

Potential benefit: If successful, this therapy could provide a more effective treatment option for patients with chronic Hepatitis B, potentially leading to better viral suppression and improved liver health.

How similar studies have gone: While this approach is being evaluated in this trial, similar combination therapies have shown promise in other studies, indicating potential for success.
