•3. Patients in group A and B must be HBsAg positive.
•4. Patient is willing and able to comply with the study drug regimen and all other study requirements.
•5. The patient is willing and able to provide written informed consent to partecipate in the study.

•4. Patient has evidence of renal insifficency defined as patient requiring dialysis or having an estimated creatinine clearance below 50 mL/min, as estimated by the Cockcroft-Gault formula:
•Calculation for Males:
•CrCl(mL/min)=(140-age in yr)x(wt in Kg)/(serum creatinine in g/dL)x(72)
•Calculation for females:
•CrCl(mL/min)=0.85x(140-age in yr)x(wt in Kg)/(serum creatinine in g/dL)x(72)
