Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Treatment of multidrug resistant (MDR) chronic hepatitis B (CHB) is still a challenging issue. Hence, the investigators will perform a multicenter prospective cohort study for the evaluation of tenofovir disoproxil fumarate (TDF)-based therapy for MDR CHB at real life settings.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Inclusion criteria were CHB patients with resistance to more than two classes of nucleos(t)ide analogues (NA) and hepatitis B virus (HBV) DNA level ≥200 IU/mL.

Patients will receive either TDF-base combination therapy or TDF monotherapy. The primary end point is virologic response (VR) defined by an undetectable HBV DNA (\<20 IU/mL) at month 36.
