Male and female patients of reproductive potential must agree to employ an effective barrier method of birth control during the study and for 3 months following discontinuation of study drug.

• Serum creatinine >2.0.
• Total serum bilirubin >2.0 mg/dl. AST(SGOT) and ALT (SGPT) more than 2.5 x the upper limit of normal range (ULN) at the laboratory where the analyses is performed.
