Gedetailleerde beschrijving
To determine the efficacy of treatment with 8 weeks of entecavir followed by 40 weeks of both entecavir and peginterferon in the treatment of chronic hepatitis B in hepatitis B "e" antigen (HBeAg) positive adults who are in the immune tolerant phase.
To evaluate safety and sustained responses after treatment with entecavir and peginterferon alfa-2a in the treatment of chronic hepatitis B in HBeAg positive adults who are in the immune tolerant phase.
A single arm treatment study of 8 weeks of entecavir followed by 40 weeks of both entecavir and peginterferon alfa-2a in adults with HBeAg-positive chronic hepatitis B with normal or near normal alanine aminotransferase (ALT) levels and high serum levels of hepatitis B virus (HBV) DNA ("immune tolerant" HBeAg-positive chronic hepatitis B). All participants followed for 48 weeks after treatment discontinuation (week 96 for those who completed treatment).

Incidentie van ernstige ongewenste voorvallen (SAE's) per persoonsjaar
Tijdsspanne: Van de eerste behandeling tot het einde van de behandeling (tot 48 weken) en het einde van de follow-up (tot 96 weken)
|
De incidentie wordt berekend als het aantal SAE's gedeeld door het aantal persoonsjaren observatie, wat de som is, over alle deelnemers, van het aantal jaren tussen het begin van de behandeling en het einde van de behandeling, of het einde van de follow-up -up, respectievelijk.

|
Lack of data was considered to be treatment failure.

Incidence of Adverse Events (AEs) Per Person-Year of Observation
Tijdsspanne: From first treatment to the end of treatment (up to 48 weeks) and the end of follow-up (up to 96 weeks)
|
The number of AEs includes both AEs and Serious Adverse Events (SAEs).
The incidence is calculated as the number of AEs divided by the number of person-years of observation, which is the sum, across all participants, of the number of years between the start of treatment and the end of treatment, or the end of follow-up, respectively.
