New hope for hepatitis delta: phase 3 trial launches
NCT ID NCT07200908
First seen Jun 27, 2026 · Last updated Aug 26, 2026 · Updated 2 times
Summary
This phase 3 trial compares a new drug, brelovitug, to an existing treatment (bulevirtide) for chronic hepatitis delta, a serious liver infection. About 172 adults with the infection will receive either drug to see which better controls the virus and normalizes liver enzymes. The goal is to find a more effective long-term treatment option.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- brelovitug (also called BJT-778)
- What this could lead to
- If it works, this could offer a more effective long-term treatment option for people with chronic hepatitis delta, potentially improving liver health and reducing the virus.
- What could go wrong
- This is a phase 3 trial, but it's still early to know if brelovitug is truly better or safer than the existing drug. Side effects are possible, and the study is relatively small (172 people).
