What this trial studies

This multicenter, randomized, double-blind, parallel group clinical study aims to evaluate the efficacy and safety of Burfiralimab (hzVSF-v13) in combination with an oral antiviral agent in patients with chronic hepatitis B. Participants who have been on stable antiviral treatment for at least 24 weeks will be randomized into three groups: one receiving Burfiralimab 50 mg, another receiving Burfiralimab 200 mg, and a control group receiving a placebo. The study will follow participants for 48 weeks, measuring changes in HBsAg levels to assess treatment effectiveness.

Who should consider this trial

Good fit: Ideal candidates are adults diagnosed with chronic hepatitis B who have been on stable antiviral therapy for at least 24 weeks.

Not a fit: Patients with significant liver disease from causes other than chronic HBV infection or those with uncontrolled diabetes or hypertension may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new effective treatment option for patients with chronic hepatitis B.

How similar studies have performed: While similar studies have explored antiviral combinations, the specific approach of using Burfiralimab in this context is novel.
