Conditions
Brief summary
This is a multicenter, randomized, double-blind, placebo-controlled, multiple-ascending dose phase Ib study of HH-003 injection, which is a monoclonal antibody targeting Hepatitis B virus. This study aims to evaluate the safety, tolerability and pharmacokinetics of HH-003 injection in treatment-naive participants chronically infected with hepatitis B virus.
