Phase 1
Not yet recruiting
Conditions
Hepatitis B, Chronic
Interventions
Drug: TQA3038 injection/placebo
Registration Number
NCT06452693
Lead Sponsor
Chia Tai Tianqing Pharmaceutical Group Co., Ltd.
Brief Summary

This study is divided into two parts. Phase Ib is a randomized, double-blind, placebo-controlled trial, designed to evaluate the safety, tolerability, pharmacokinetic characteristics, preliminary efficacy, and immunogenicity of TQA3038 injection in patients with chronic hepatitis B. It is expected to include 72 subjects. Phase IIa adopted an open-label, randomized, parallel-controlled design, with a total of 90 subjects included, mainly evaluating the changes in serum HBsAg compared to baseline at the end of the 48th week.
