ACT201 Injection in Participants With Chronic Hepatitis B (CHB) on Nucleos(t)Ide Analog Therapy - Phase Ib

4. november 2026 opdateret af: Xiamen Amoytop Biotech Co., Ltd.

A Multicenter, Randomized, Open-label Phase Ib Clinical Trial to Evaluate the Safety and Efficacy of ACT201 Injection in Participants With Chronic Hepatitis B (CHB) Receiving Nucleos(t)Ide Analog Therapy

This is a multicenter, randomized, open-label, parallel-controlled Phase Ib clinical trial. It aims to evaluate the safety and preliminary efficacy of ACT201 Injection combined with standard therapy (PegIFNα, NA) in participants with chronic hepatitis B who are receiving NA treatment. A total of 40 participants with chronic hepatitis B will be enrolled. Eligible participants should have stable NA treatment, HBV DNA < 100 IU/mL, negative HBeAg, and HBsAg ≤ 100 IU/mL. They will be randomized into four treatment groups at a 1:1:1:1 ratio.
