E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the efficacy of Pegasys¿ + lamivudine compared with an untreated control in children with CHB, as measured by loss of HBsAg 24 weeks post-end of treatment/end of untreated observation. |
Valutare l'efficacia di Pegasys¿ + lamivudina rispetto a un controllo senza trattamento in bambini affetti da epatite B cronica (CHB), misurandola in termini di perdita di HBsAg 24 settimane dopo la fine del trattamento/fine dell'osservazione senza trattamento. |
|
E.2.2 | Secondary objectives of the trial |
¿To evaluate efficacy of Pegasys¿ + lamivudine compared with an untreated control in children with CHB, as measured by seroconversion to anti-HBs, seroconversion to anti-HBe, loss of HBeAg, and HBV DNA levels, at 24 weeks post-end of treatment/end of untreated observation ¿ To evaluate efficacy of Pegasys¿ + lamivudine in children with CHB, as measured by seroconversion to anti-HBs, seroconversion to anti-HBe, loss of HBsAg, loss of HBeAg, HBV DNA levels, and at 1, 2, 3, 4, and 5 years post-end of treatment |
-Valutare l'efficacia di Pegasys¿ + lamivudina rispetto a un controllo senza trattamento in bambini affetti da epatite B cronica (CHB), misurandola in termini di sieroconversione ad anti-HBs, sieroconversione ad anti-HBe, perdita di HBeAg e dei livelli di HBV DNA 24 settimane dopo la fine del trattamento/fine dell'osservazione senza trattamento. - Valutare l'efficacia di Pegasys¿ + lamivudina in bambini affetti da epatite B cronica (CHB), misurandola in termini di sieroconversione ad anti-HBs, sieroconversione ad anti-HBe, perdita di HBsAg, perdita di HBeAg, e dei livelli di HBV DNA a 1, 2, 3, 4 e 5 anni dopo la fine del trattamento. |

E.3 | Principal inclusion criteria |
• Male and female patients 3 to less than 18 years of age at baseline (12– 17 years of age at baseline in Russia) • Positive for HBsAg and HBeAg for more than 6 months prior to baseline • Detectable HBV-DNA (> 10,000 copies/mL [> 2000 IU/mL]) (as measured by PCR or hybridization) on at least 2 occasions at least one month apart with the latest determination obtained = 42 days prior to baseline. |

|
E.4 | Principal exclusion criteria |
Patients who have had any previous anti-HBV treatment, or who are co-infected with hepatitis A virus (HAV), HCV, hepatitis D virus (HDV) or HIV, or who have decompensated liver disease will be excluded. |
Vengono esclusi pazienti trattati con altri trattamenti anti-HBV o co-infettati dal virus dell'epatite A (HAV), HCV, virus dell'epatite D (HDV), HIV, o che hanno epatopatia non compensata |
|
E.5 End points |
E.5.1 | Primary end point(s) |
The primary efficacy endpoint is defined as loss of HBsAg at 24 weeks post-end of treatment (follow-up Week 24)/end of untreated observation (Week 80). |
L'endpoint primario di efficacia è la perdita di HBsAg a 24 settimane dopo la fine del trattamento (follow-up Week 24) /fine dell'osservazione senza trattamento (Week 80). |
