Inclusion criteria

* Able to understand the study requirements and provide written informed consent before and study assessment is performed. * Male or female patients ≥ 18 to 70 years of age. * Recipients of a de novo renal allograft from a heart-beating deceased, living unrelated, or non-HLA identical living related donor. * Recipients of a kidney with a cold ischemia time (CIT) less than 30 hours.

Exclusion criteria

* Multiple-organ transplant recipients * Subjects who have received a kidney allograft previously * Recipient of a kidney from an HLA identical living related donor * Recipient of a kidney from a donor after cardiac death * Subjects at high immunological risk for rejection
