Study Endpoints

Primary Endpoints

The primary outcome measure will be the safety assessment.
Safety assessment will be calculated from the date of enrollment for a maximum of 15 months.

safety criteria will be: * Occurrence of AEs, * Physical examination, * Laboratory tests, * Vital signs and ECG,

Mean change in ALT as assessed by an ANCOVA with the following covariates: treatment, gender, subject and time and a non parametric test (Conover-Salsburg).
Mean change in ALT at V1 (Day15) and V2 (Day 30)

Secondary Endpoints

Secondary Outcome Measures
Every 3 month, from the date of enrollment for a maximum of 15 months.
Sustained reduction in ALT to either 50% of baseline or value < or equal to ULN. Sustained reduction serum AST and GGT.Clinical and laboratory safety.
V1 (Day 15), V2 (Day 30) and V3 (Day 60)
