  • Patient with prior kidney transplant or non-renal solid organ transplant.
  • Patient has a known contraindication to any of the protocol-specified treatments.
  • Patient had been diagnosed with a malignancy within 5 years prior to study entry, excluding non-metastatic basal or squamous cell carcinoma of the skin.
  • Female patients who are breast-feeding.
  • Female patients with a positive pregnancy test.
