Study on the Treatment of Hepatitis B Virus(HBV) Infected Individuals With Peginterferon α-2b Combined With NA.

From baseline day 1, take NA orally once daily until the drug can be discontinued. Concurrently, combine with Peg-IFN α-2b 180μg, administered subcutaneously once a week for 48-96 weeks (if the surface antigen is not converted to negative at week 48, continue Peg-IFN α-2b treatment, but the course of treatment should not exceed 96 weeks). Discontinue Peg-IFN α-2b (while maintaining continuous oral administration of NA), and continue taking NA orally.

Starting from the first day of enrollment, take NA orally once a day.
