Efficacy and Safety of Antiviral Therapy With Peg-interferon for Chronic Hepatitis B Complicated With Nonalcoholic Fatty Liver Disease（OCEAN PROJECT）
- Conditions
- Nonalcoholic Fatty Liver DiseaseChronic Hepatitis b
- Interventions
- Drug: Peg-Interferon α
- Registration Number
- NCT06368882
- Brief Summary
This is a prospective, multicenter, open-label, non-randomized controlled real-world study to explore the efficacy and safety and to accumulate more evidence-based medical data of an antiviral treatment programme for chronic viral hepatitis B with nonalcoholic fatty liver disease.
A total of 1500 patients with chronic hepatitis B complicated with nonalcoholic fatty liver disease are divided into test group (1000 patients receiving PEG-IFNα-based antiviral therapy (combined NAs or Peg-IFNα monotherapy) and control group（500 patients receiving NAs monotherapy） according to their treatment intention. Laboratory and medical data from specified follow-up points are collected, and adverse events and drug combinations are recorded detailly.
The primary efficacy indicator is HBsAg clearance at 48 weeks of treatment, and the secondary indicators included: (1) HBsAg clearance at 96 weeks of treatment, (2) Cumulative HBsAg clearance at week 24、120、144、168、192、216 and 240; (3) The improvement of liver function level(ALT, AST, TBIL, etc.), blood lipid (TC, TG, LDL-C, HDL-C, etc.), fasting blood glucose, insulin resistance index (HOMA-IR), controlled attenuation parameter, body mass index , liver stiffness measurement, liver histological fibrosis, FIB-4 index from baseline; (4)Incidence of liver cirrhosis and hepatocellular carcinoma during follow-up.
The security assessment includes adverse events, vital signs, and imaging.

Group Intervention Description Treatment Group Peg-Interferon α Treatment Group \[PEG-IFNα-based antiviral therapy (combined with NAs or PEG-IFNα monotherapy)\]: PEG IFNα injection 180 μg is administrated subcutaneously on the first day of the first week, weekly; If HBsAg is negative within 48 weeks of treatment, Peg IFNα combined with NAs or PEG-IFNα monotherapy was continued for 12 weeks, with a maximum of 96 weeks, and the patients are followed up to 240 weeks after the end of treatment. If the patient doesn't achieve HBsAg negative conversion within 48 weeks of treatment, the maximum duration of Peg-IFNα treatment is 96 weeks, and the NAs treatment can be continued until the time of discontinuation where combined treatment programme is used (if HBsAg negative, the consolidation treatment for not less than 24 weeks, and if HBsAg positive still, the treatment with NAs continue). The total of duration of treatment or follow-up is 240 weeks after the end of treatment.
