About this trial
The goal of this clinical trial is to evaluate the safety, tolerability, immunogenicity and Pharmacokinetics (PK) characteristics of AHB-171 Injection in healthy participants (Part A) and participants with chronic hepatitis B (CHB, Part B), and assess its preliminary efficacy in CHB participants.
