• •* Partner(s) using oral, injected, or implanted methods of hormonal contraceptives
• •* Subject and/or partner(s) using double-barrier method.
• •Subjects with Normal Hepatic Function
• •Judged to be in general good health based upon the results of a medical history, physical examination, laboratory profile (including liver function parameters within the limits of normal) and 12-lead electrocardiogram (ECG).
