Main objective of the trial

This randomized, controlled, parallel-group, open-label, multicenter study was designed to evaluate the use of peginterferon alfa-2a (PEG-IFN) monotherapy versus untreated control in pediatric participants with hepatitis B envelope antigen (HBeAg)-positive chronic hepatitis B (CHB) in the immune active phase. The study compared efficacy and safety between groups and evaluated the pharmacokinetics of PEG-IFN following administration of a body surface area (BSA)-based dosing regimen.

Protection of trial subjects

The investigators have ensured that this study was conducted in full conformance with the principles of the Declaration of Helsinki or with the laws and regulations of the country in which the research was conducted, whichever afforded the greater protection to the individual. The study has fully adhered to the principles outlined in “Guideline for Good Clinical Practice” International Council for Harmonisation (ICH) Tripartite Guideline or with local law if it afforded greater protection to the participant. For studies conducted in the European Union (EU)/European Economic Area (EEA) countries, the investigators have ensured compliance with the EU Clinical Trial Directive (2001/20/EC). The investigators have additionally ensured adherence to the basic principles of “Good Clinical Practice” as outlined in the current version of 21 Code of Federal Regulations, subchapter D, part 312, “Responsibilities of Sponsors and Investigators”; part 50, “Protection of Human Subjects”; and part 56, “Institutional Review Boards”. In other countries where “Guideline for Good Clinical Practice” exists, Roche and the investigators have strictly ensured adherence to the stated provisions.

Group A: PEG-IFN Monotherapy Without Advanced Fibrosis

Arm description

Participants without advanced fibrosis were randomized and received PEG-IFN monotherapy for 48 weeks with a 24-week follow-up and an additional 4.5-year extended follow-up. Each dose of 45 to 180 micrograms (mcg) was based on BSA and given as a once-weekly subcutaneous (SC) injection for 48 weeks. BSA-based dosing was as follows: 0.51-0.53 square meters (m^2), 45 mcg; 0.54-0.74 m^2, 65 mcg; 0.75-1.08 m^2, 90 mcg; 1.09-1.51 m^2, 135 mcg; greater than (>) 1.51 m^2, 180 mcg.

Dosage and administration details

Peginterferon alfa-2a was given as SC injection once weekly for 48 weeks and dosed according to BSA category as specified in the protocol. Possible doses ranged from 45 to 180 mcg.

Group B: Untreated Control Without Advanced Fibrosis

Arm description

Participants without advanced fibrosis were randomized and were evaluated for 48 weeks with a 24-week follow-up and an additional ongoing 4.5-year extended follow-up. As the study is open-label, participants did not receive any investigational or placebo treatment during the 48-week principal observation period (POP). For ethical reasons, participants in Group B had a reduced visit schedule (every 12 weeks) compared to participants in Group A through the end of 24-week follow-up. After completing the POP, the same PEG-IFN regimen administered in Group A was offered to participants in Group B who had not experienced hepatitis B envelope antigen (HBeAg) seroconversion. The offer remained for up to 1 year following the Week 48 visit. From the time a given participant switched to PEG-IFN, he/she was no longer included in Group B.

Each dose of 45 to 180 mcg was based on BSA and given as a once-weekly SC injection for 48 weeks. BSA-based dosing was as follows: 0.51-0.53 m^2, 45 mcg; 0.54-0.74 m^2, 65 mcg; 0.75-1.08 m^2, 90 mcg; 1.09-1.51 m^2, 135 mcg; >1.51 m^2, 180 mcg.

Participants without advanced fibrosis were randomized to receive PEG-IFN monotherapy or were evaluated as untreated control for 48 weeks with a 24-week follow-up and an additional ongoing 4.5-year extended follow-up. Participants with advanced fibrosis were allocated (not randomized) to receive PEG-IFN monotherapy for the same duration. For those who received PEG-IFN treatment, each dose of 45 to 180 mcg was based on BSA and given as a once-weekly SC injection for 48 weeks. BSA-based dosing was as follows: 0.51-0.53 m^2, 45 mcg; 0.54-0.74 m^2, 65 mcg; 0.75-1.08 m^2, 90 mcg; 1.09-1.51 m^2, 135 mcg; >1.51 m^2, 180 mcg.

Reporting group title

Group A: PEG-IFN Monotherapy Without Advanced Fibrosis

Reporting group description

Participants without advanced fibrosis were randomized and received PEG-IFN monotherapy for 48 weeks with a 24-week follow-up and an additional ongoing 4.5-year extended follow-up. Each dose of 45 to 180 mcg was based on BSA and given as a once-weekly SC injection for 48 weeks. BSA-based dosing was as follows: 0.51-0.53 m^2, 45 mcg; 0.54-0.74 m^2, 65 mcg; 0.75-1.08 m^2, 90 mcg; 1.09-1.51 m^2, 135 mcg; >1.51 m^2, 180 mcg.

Group C: PEG-IFN Monotherapy With Advanced Fibrosis

Reporting group description

Participants with advanced fibrosis were allocated (not randomized) to receive PEG-IFN monotherapy for 48 weeks with a 24-week follow-up and an additional ongoing 4.5-year extended follow-up. Each dose of 45 to 180 mcg was based on BSA and given as a once-weekly SC injection for 48 weeks. BSA-based dosing was as follows: 0.51-0.53 m^2, 45 mcg; 0.54-0.74 m^2, 65 mcg; 0.75-1.08 m^2, 90 mcg; 1.09-1.51 m^2, 135 mcg; >1.51 m^2, 180 mcg.

Reporting group title

Group D: Switch to PEG-IFN Monotherapy

Reporting group description

Participants without advanced fibrosis who did not receive treatment and had not experienced HBeAg seroconversion were allowed to switch to PEG-IFN monotherapy. Treatment was given over 48 weeks with a 24-week follow-up and an additional ongoing 4.5-year extended follow-up. Each dose of 45 to 180 mcg was based on BSA and given as a once-weekly SC injection for 48 weeks. BSA-based dosing was as follows: 0.51-0.53 m^2, 45 mcg; 0.54-0.74 m^2, 65 mcg; 0.75-1.08 m^2, 90 mcg; 1.09-1.51 m^2, 135 mcg; >1.51 m^2, 180 mcg. Because participants could switch from Group B to Group D for up to 1 year following the Week 48 visit, not all participants had reached FU Week 24 at time of analysis.

Were there any global substantial amendments to the protocol? Yes

24 Oct 2011

The protocol was amended primarily for the addition of exploratory biomarker objectives. Corresponding laboratory procedures, including the collection of DNA specimens, were added to the study assessments. The timeline for liver elasticity assessment was also expanded to FU Year 2.

04 Apr 2012

Under this protocol amendment, liver biopsy was now required within 2 years of Baseline to ensure participants had not progressed to cirrhosis, and a liver elasticity assessment was added at EOT/POP. New entry criteria were also added for participants in Group B who opted to switch to PEG-IFN.

17 May 2013

Some liver biopsy assessments were removed to minimize participant discomfort, and ophthalmological examinations could now be performed 6 months before Baseline. Eligibility criteria were also updated for both administrative and safety purposes. Dose reduction guidelines were updated, and additional safety monitoring parameters were added.

28 May 2014

Eligibility criteria were updated including the removal of HBV antibody screening requirements, explanation of normal hemoglobin range, exclusion of participants with renal impairment. Additionally, participants with ALT > 10 × ULN were now excluded from switching to PEG-IFN in Group D. Scoring guidelines for liver fibrosis were also added.

Were there any global interruptions to the trial? No

Limitations of the trial such as small numbers of subjects analysed or technical problems leading to unreliable data.

Results presented above include final analyses of the primary endpoint and most secondary endpoints. Group D had not reached FU Week 24 at time of analysis, so basic safety data were reported. New/updated data will be reported in the final results.
