Study start date: January 22, 2025

Actual date on which the first participant was enrolled.

This study aims to test a new treatment called TVAX-008, which is given as an injection, for people with chronic Hepatitis B. It focuses on those who have specific levels of the Hepatitis B surface antigen in their blood, whether they have been treated before with certain drugs called siRNA or ASO, or have never had treatment for Hepatitis B infection. The goal is to see if TVAX-008 can effectively manage the virus and improve patient outcomes, addressing a significant need for better treatment options in this condition. In this study, participants receive either the TVAX-008 injection or a placebo, which is a harmless substance, without knowing which one they are getting, to ensure unbiased results. Researchers closely monitor participants to evaluate how well the treatment works and its safety. By comparing the health outcomes between the group receiving the real treatment and the placebo group, the study assesses the potential benefits and any side effects of TVAX-008.
