New treatment option for Hepatitis B, Chronic
Official title Phase 2 Study of AHB-137 in HBeAg Negative Chronic Hepatitis B (CHB) Participants in Asia Pacific Region
ClinicalTrials.gov ID: NCT07370207
What this study is testing
What is AHB-137?
AHB-137 is an investigational medicine, given as an injection under the skin, being studied as a potential treatment for hepatitis b, chronic.
Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- This study is a randomized, open-label, multicenter phase 2 clinical trial to evaluate the efficacy and safety of AHB-137 injection in participants with HBeAg-negative CHB treated with Nucleos(t)ide Analogue (NAs).
- Phase 2: a mid-size study of how well it works
- Which group you join is decided by chance.
A plain-language read of the study's public ClinicalTrials.gov listing. The study team confirms the details.
