Study Summary

This trial will test a new treatment for people with inactive chronic hepatitis B who have low levels of hepatitis B surface antigen. The treatment will be evaluated for its ability to fight the virus, its safety, and its ability to provoke an immune response.

Who is the study for?
This trial is for men and women aged 18 to 65 with inactive Chronic Hepatitis B, who haven't been treated before. Participants should have specific levels of HBsAg and HBV DNA, normal liver function tests, and must have had CHB for at least a year.Check my eligibility
What is being tested?
The study is testing the effects of a new treatment called HepTcell compared to a placebo in patients with inactive CHB. It aims to see if HepTcell can help control the virus better and how safe it is.See study design
What are the potential side effects?
Possible side effects from HepTcell could include typical immune response symptoms like fever or fatigue, injection site reactions, or changes in liver enzymes. The exact side effects will be monitored throughout the trial.
