Prospective Cohort Study on PEG-IFN-α-2b in Improving Clinical Cure Rate of Pediatric Patients With Chronic Hepatitis B
Sponsor: Nanfang Hospital, Southern Medical University
Summary
In this study, comparisons will be made between the treatment group (which will receive pegylated interferon alfa-2b treatment) and the observation group (which will receive no drug treatment or be treated with nucleos(t)ide analogs). The primary objectives are to address the following questions: compare the efficacy evaluation indicators (with clinical cure rate as the primary one) between the pegylated interferon alfa-2b treatment group and the observation group; assess whether pegylated interferon alfa-2b treatment improves the clinical cure rate in patients with chronic hepatitis B virus (HBV) infection aged 3 years and above but under 18 years (adolescents and children); and explore optimized antiviral treatment regimens for adolescents and children with chronic HBV infection. The secondary objectives are to address the following questions: compare the immune response characteristics between adolescents and children with chronic HBV infection who achieved functional cure after pegylated interferon alfa-2b treatment and those who did not; investigate the immune mechanism underlying the achievement of functional cure in adolescents and children with chronic HBV infection treated with pegylated interferon alfa-2b; and identify plasma markers associated with treatment efficacy for predicting therapeutic outcomes.

Peginterferon alfa-2b Injection
Subjects in the treatment group will receive pegylated interferon alfa-2b treatment. The dosage will be determined based on height and weight, calculated as 180 μg × body surface area / 1.73 m². The administration method is subcutaneous injection once per week for 48 consecutive weeks. Follow-up visits will be conducted during the treatment period (at Week 4, Week 8, Week 12, Week 24, Week 36, and Week 48) and after the end of treatment (at Week 12 post-treatment and Week 24 post-treatment). The total number of injections administered will not exceed 96.
