• Creatinine clearance (CrCl) ≥ 30 mL/minute calculated by Cockcroft-Gault formula

10. Life expectancy of at least 12 weeks

11. Females of child bearing potential must have a negative pregnancy test during screening and must not be breastfeeding or intending to become pregnant during the study.

12. Male patients with female partners of child-bearing potential must be willing to use two forms of acceptable contraception, including one barrier method, during their participation in this study and for 16 weeks following the last dose of the study.
