- Known history of drug or alcohol abuse within 1 year of screening
- Malignancy (other than resected cutaneous basal or cutaneous squamous cell carcinoma, or treated in situ cervical cancer considered cured) within 5 years of screening visit (if a malignancy occurred > 5 years ago, subject is eligible with documentation of disease free state since treatment)
- Immunosuppressive therapy with either cyclosporine A, tacrolimus, or mycophenolate mofetil, within 1 month prior to baseline
