Run by The Affiliated Nanjing Drum Tower Hospital of Nanjing University Medical School · NCT05661786 · Data updated 2026-11-12

This study is trying to learn more about patients with chronic hepatitis B who are in a tricky stage of their illness to see how their condition changes and if they might need treatment.

Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are treatment-naïve adults aged 18 and older who are HBeAg-negative and have specific HBV DNA and ALT levels.

Probably not a fit

Patients with coexisting liver diseases, cirrhosis, or those with a history of substance abuse may not benefit from this study.

What this trial studies

This observational study focuses on patients with chronic hepatitis B (CHB) who are HBeAg-negative and fall into an indeterminate phase, where their HBV DNA and alanine aminotransferase levels do not clearly fit into established classifications. The study aims to monitor these patients to better understand their disease progression and the potential need for antiviral treatment. By analyzing the clinical outcomes of this specific patient group, the research seeks to improve individual management strategies for chronic hepatitis B. The study will include treatment-naïve patients who meet specific eligibility criteria, ensuring a focused approach to this under-researched phase of CHB.

Why it matters

Potential benefit: If successful, this study could lead to improved management strategies for patients with chronic hepatitis B in the indeterminate phase, potentially reducing the risk of liver complications.

How similar studies have gone: While there is limited research specifically on the indeterminate phase of chronic hepatitis B, studies on other phases of CHB have shown promising results with antiviral treatments.
