Summary

This study tests a therapeutic vaccine called TherVacB in 81 adults with chronic hepatitis B who are already on antiviral medication. The vaccine is given as a series of shots to boost the immune system and lower hepatitis B virus levels. The main goals are to check safety and see if the vaccine can reduce virus markers in the blood.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

TherVacB (HEPLISAV B with or without HBcoreAg plus MVA-HBVac)

What this could lead to

If successful, this could lead to a treatment that helps control chronic hepatitis B without lifelong antiviral pills.

What could go wrong

This is an early-phase trial with only 81 participants, so safety and immune response are still being tested. The vaccine may not lower virus levels enough or could cause liver side effects.
