ClinicalTrials.gov Identifier:
NCT01519960
First received: December 6, 2011

  Purpose

This parallel group, open label study will evaluate the safety and efficacy of Pegasys (peginterferon alfa-2a) versus untreated control in children (age 3 years to <18 years at baseline) with HBeAg positive chronic hepatitis B. Children without advanced fibrosis and without cirrhosis will be randomized 2:1 to treatment Group A, receiving Pegasys 45-180 mcg subcutaneously weekly for 48 weeks, or to the untreated control Group B. Children with advanced fibrosis will be assigned to treatment group C and receive 48 weeks of treatment with Pegasys. Children in the untreated control Group B who have not experienced seroconversion 48 weeks after randomization may enter the Switch Arm to receive 48 weeks of Pegasys treatment. This offer will be available for 1 year following 48 weeks from randomization. Anticipated time on study treatment is 48 weeks. All subjects will be followed up for 5 years after the end of treatment (A,C,Switch)/principal observation (B) period.

Further study details as provided by Hoffmann-La Roche:

Primary Outcome Measures:
  • HBeAg seroconversion (loss of HBeAg and presence of anti-HBe) 24 weeks after end of treatment/principal observation period with a further 4.5 years of follow-up [ Time Frame: 24 weeks post-treatment/principal observation period ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • HBsAg seroconversion (loss of HBsAg and presence of anti-HBs) [ Time Frame: up to 8 years ] [ Designated as safety issue: No ]
  • Loss of HBeAg/HBsAg [ Time Frame: up to 8 years ] [ Designated as safety issue: No ]
  • Serum alanine aminotransferase (ALT) levels [ Time Frame: up to 8 years ] [ Designated as safety issue: No ]
  • Proportion of normal ALT [ Time Frame: up to 8 years ] [ Designated as safety issue: No ]
  • HBV DNA levels [ Time Frame: up to 8 years ] [ Designated as safety issue: No ]
  • Change in liver elasticity (elastography) [ Time Frame: from baseline to Week 72 ] [ Designated as safety issue: No ]
  • Group C: Change in histological findings (liver biopsy) [ Time Frame: from baseline to Week 72 ] [ Designated as safety issue: No ]
  • Pharmacokinetics: Area under the concentration-time curve (AUC) [ Time Frame: Weeks 1 and 24, pre-dose and 24-48, 72-96 and 168 hours post-dose ] [ Designated as safety issue: No ]
  • Safety: Incidence of adverse events [ Time Frame: up to 8 years ] [ Designated as safety issue: No ]
  • Safety: Growth [ Time Frame: up to 8 years ] [ Designated as safety issue: No ]
