A Study to Evaluate Addition of Peginterferon Alfa-2a to Chronic Hepatitis B (CHB) Patients Treated With NAs

• Status: Unknown status
• Trial end date: 2018-12-01
• Target enrollment: 0
• Participant gender: All

Summary

This study evaluates whether addition of Peginterferon alfa-2a to CHB Patients Treated with nucleoside analogues (NAs) can enhance the rate of HBsAg clearance at end of treatment. This study is a Randomized, open-label, multi-center study.

The CHB patients with NAs treatment and have achieved HBV DNA <15 IU/ml、HBeAg <100 PEIU/ml、HBsAg positive and HBsAg<1500 IU/ml will be randomized into 2 groups:

Group 1 (Combination group): Maintain NAs treatment while add 48-week standard treatment by Peginterferon alfa 2a 180µg/week Group 2 (Mono NA group) : Maintain NAs treatment for 49 weeks. Note: NAs including: LAM, ADV, ETV, or TDF.

• Phase: Phase 4
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: Henan Provincial Hospital; Henan Provincial People's Hospital
• Treatments: Interferon-alpha; Peginterferon alfa-2a
