Higher dose of hepatitis b drug put to the test in damaged livers
NCT ID NCT07816094
First seen Sep 11, 2026 · Last updated Sep 11, 2026
Summary
Researchers are testing whether a higher daily dose of the antiviral drug entecavir suppresses hepatitis B virus better than the standard lower dose in adults whose livers are already scarred and failing. The trial enrolls 48 people with hepatitis B and decompensated cirrhosis. Participants take either 0.5 mg or 1.0 mg of entecavir once a day for 24 weeks, and researchers measure how much the virus levels drop, along with liver function and safety.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- entecavir, an antiviral drug taken by mouth
- What this could lead to
- If one dose works better, doctors could have clearer guidance on how to suppress hepatitis B in people whose livers are already badly damaged.
- What could go wrong
- This is a small, short trial of 48 people. It may not show a clear difference between the doses, and it cannot prove that suppressing the virus reverses cirrhosis or prevents liver cancer.
