  • Female subject of child bearing potential must have a negative serum pregnancy test within 7 days prior to enrollment or upon hospitalization and must agree to maintain effective birth control during the study
  • All sexually active male subjects must agree to use an adequate method of contraception throughout the study period and for 90 days after the last dose of study drug and agrees to no sperm donation until the end of the study, or for 90 days after the last dose of study drug, whichever is longer
  • Subject must be willing and able to comply with the study requirements including prohibited concomitant medication restrictions

You may not qualify if:

  • Subject has previously received or is receiving an organ transplant other than a kidney
  • Recipient has a positive T or B cell crossmatch
  • Subject has ABO blood type incompatibility with their donor

  • Subject has abnormal chest x-ray indicative of acute or chronic lung disease on a prior examination within 3 months prior to randomization
  • Subject has abnormal electrocardiogram (ECG) considered as clinically significant on a prior examination within 3 months prior to randomization
  • Subject has uncontrolled intercurrent illness, including, but not limited to ongoing or active infection, any clinically significant cardiac disease, seizure disorder, or psychiatric illness/social situations that would limit compliance with study requirements
