E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Evaluation of study drug efficacy with respect to virological, serological, and histological response of combined therapy treatment with Peg-IFN alfa 2a (sc.)and Adefovir 10 mg/die for 48 weeks, followed by Adefovir 10 mg/die alone for further 96 weeks versus Adefovir 10 mg/die alone for 144 weeks in subjects with chronic hepatitis B, HBeAg negative |
|
E.2.2 | Secondary objectives of the trial |
Biochemistry response- defined as transaminasis normalization; Serological response- defined as seroconversion to HBsAg negative or to anti-HBs positive; ccDNA intrahepatics levels reductions; Histological response- defined as at least 2 score points of the Histological Activity Index (according to Knodell) and at least 1 score point (according to Scheuer) of fibrosis reduction; Development of virological breakthrough (HBV-DNA increased over 1 log) Appearance of clinical events Evidence of N236T and A181V mutations |
