  • have a creatinine clearance of less than 20 mL/min
  • have a body mass index of less than or equal to 28
  • In the case of women of childbearing potential (WOCBP), must have a negative pregnancy test and avoid pregnancy throughout the study and 8 weeks after final dose of study drug.
  • WOCBP must use two adequate methods of contraception.
  • A male subject of fathering potential must use an adequate method of contraception to avoid conception throughout the study and for up to 8 weeks after the last dose of study drug to minimize the risk of pregnancy.
