Pharmacokinetic/Pharmacodynamic of Albinterferon Alfa-2b in Chronic Hepatitis B, eAg+, Infection Subjects

January 5, 2011 updated by: Novartis Pharmaceuticals

A Pharmacokinetic/Pharmacodynamic Evaluation of ABF656 in Subjects With Chronic Hepatitis B, e Ag+, Infection.

This study will assess the efficacy of ABF656 in chronic hepatitis B characterized by HBeAg positivity. The study is designed to establish a dose response and safety relationship sufficient to allow the subsequent design and conduct of Phase 3 trials. The trial is also designed to generate the PK data in hepatitis B patients to satisfy regulatory requirements in China.

Description

Inclusion Criteria:
