简要总结

This is an open-label phase IIa study of HH-003 to evaluate its antiviral activity and safety in subjects with chronic hepatitis B and hepatitis D co-infection. HH-003 is a human monoclonal antibody targeting the pre-S1 domain of the HBV large envelope protein. It blocks engagement of preS1 with sodium taurocholate co-transporting polypeptide (NTCP), the cellular receptor for HBV/HDV.
