Official title Sequential PEG-IFN for HBV After Ending RNA-targeted Regimens
ClinicalTrials.gov ID: NCT06923280
What this study is testing
What is Pegylated Interferon-alpha (IFN)?
Pegylated Interferon-alpha (IFN) is an investigational medicine, given as an once-weekly, 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
- The goal of this clinical trial is to compare sequential PEG-IFNα therapy strategies in chronic hepatitis B (CHB) patients previously treated with ASO/siRNA. The main questions it aims to answer are: 1.
