3500 hepatitis b patients needed to hunt for cure biomarker
NCT ID NCT03825458
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study is creating a large collection of blood samples and health data from 3500 people with hepatitis B, including those who have already cleared the virus. Researchers will use these samples to look for viral RNA patterns that could signal a functional cure. No new treatments are being tested; the goal is to develop a better way to measure when the infection is under control.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could lead to a reliable blood test to tell when hepatitis B is functionally cured, helping doctors make better treatment decisions.
- What could go wrong
- This is an observational study that does not test any treatment. It only collects samples for future research, so it may not directly lead to a cure or new therapy.
