Must have
Be older than 18 years old
Timeline
Screening 3 weeks
Treatment Varies
Follow Up 48 weeks

Summary

This trial tests the safety & effectiveness of a new antibody-based drug to treat chronic hepatitis B in people already on medication.

Who is the study for?
Adults aged 18-70 with chronic Hepatitis B on nucleos(t)ide therapy for at least 6 months can join. They must not be pregnant, agree to use contraception, and have a stable viral load. Excluded are those with severe allergies, heart disease, recent acute infections, advanced liver fibrosis or cancerous liver lesions.
What is being tested?
The trial is testing HepB mAb19, an experimental antibody targeting the hepatitis B virus in patients already on standard treatment. It's compared against a placebo (sterile saline). The study will look at safety and how well it works to control the virus.
What are the potential side effects?
Potential side effects may include allergic reactions due to the monoclonal antibody such as skin rashes or more serious conditions like anaphylaxis. Since this is a first-in-human study, close monitoring for any unexpected side effects is critical.
