Summary

This early-stage trial tests a new therapeutic vaccine (Hepadvax) in 40 adults with chronic hepatitis B. The vaccine is designed to boost the immune system to control or possibly clear the virus. Researchers will monitor safety, viral load, and immune responses compared to a standard hepatitis B vaccine.

What this could mean

Active substance
Therapeutic hepatitis B vaccine (Hepadvax) with Advax-2 adjuvant
What this could lead to
If successful, this vaccine could help control or even clear chronic hepatitis B infection, reducing the need for lifelong antiviral medication.
What could go wrong
This is an early phase 1/2 trial with only 40 participants, so results may not apply broadly. The vaccine may not effectively reduce viral load or cause side effects.
