Is this trial a fit for you?

Likely a good fit

Adults aged 18-65 with chronic hepatitis B, no prior interference by antiviral therapy, and meeting specific liver and viral criteria.

Probably not a fit

Patients with advanced liver disease, significant comorbidities, or those who do not respond to AHB-137 may not experience benefit.

What this trial studies

This is a multicenter, randomized, double-blind, placebo-controlled phase 2 trial evaluating the safety and efficacy of AHB-137 injection in treatment-naïve adults with chronic hepatitis B. Eligible participants are 18 to 65 years old with confirmed HBV infection and no prior antiviral therapy, enrolled at sites in Beijing and Chongqing. Participants will receive either AHB-137 or placebo and will be monitored for liver-related safety and antiviral responses over the study period. The trial aims to determine whether AHB-137 can reduce HBV markers and improve liver function without unacceptable safety risks.

Why it matters

Potential benefit: If successful, participants could experience reduced HBV activity and improved liver health, with broader benefits for future patients.

How similar studies have gone: Previous phase 2 trials of similar novel therapies have shown potential antiviral activity, but results for AHB-137 are not yet established in HBV.
