| Main Objective: The main aim of the study is to investigate efficacy of a twelve months course of Phyllantus amarus on the clearance of serum HBVDNA, tested with Versant HBVDNA, in patients with CHB not suitable for standard therapies.;Secondary Objective: The principle secondary objectives of the study are:  To test level of serum HBVDNA at months 1, 3, 6, 9 ,12, and 18 to evaluate how study treatment may affect viral kinetics;  To evaluate rate of HBsAg and HBeAg (in patients HBeAg+) seroconversion at months 1, 3, 6, 9, 12 and 18;  To evaluate the rate of serum liver enzymes normalization during treatment; To evaluate the rate of persistent serum HBVDNA clearance and serum liver enzymes normalization 6 months after the end of treatment.;Primary end point(s): Determination of sieric HBVDNAwith Versant HBV TM method (detectable level 2000 cpoies/ml), wich is the standard evaluation in clinical studies on chronic Hepatitis B virus | — |
