NCT07573943

Brief Summary

Exploring the safety and efficacy of the therapy combining immune checkpoint inhibitors (anti-PD-L1 monoclonal antibody, ASC22) and pegylated interferon alfa (Peg-IFNα) in patients with CHB. Exploring new combination therapeutic schemes for hepatitis B cure, and raising the overall clinical cure rate to more than 50% without screening specific advantageous groups.
