Primary outcome measure
Two primary endpoints are to be considered:
1. Time until Bilirubin < 2 mg/dl
2. Time to hospital discharge
They are ranked according to their relevance and reliability
Secondary outcome measures
The secondary endpoints are grouped into three categories according to their meaning:
1. Endpoints related to antiviral response:
1.1 Time to clear HBsAg (HBsAg negative)
1.2 In initially HBeAg positive patients: Time to clear HBeAg (HBeAG negative)
1.3 Rate of HBsAg positive patients at 6 and 12 months, respectively, after start of therapy
1.4 Time to first occurrence of anti-HBs
1.5 In initially HBeAg positive patients: Time to first occurrence of anti-HBe
1.6 Time to clear HBV-DNA (HBV-DNA below level of detection)
2. Endpoints related to liver function:
2.1 Time to normalisation of prothrombin time (Quick >=70% ), if initially abnormal
2.2 Time to normalisation of liver enzymes ALAT, ASAT (according to the appropriate reference levels of the central laboratory)
2.3 Rate of patients progressing to fulminant hepatitis
3. Patient related endpoints:
3.1 Rate of adverse and serious adverse events
3.2 For patients with ongoing employment relationship: time to end of absence from work
