Brief summary: The purpose of this study is to assess Alefacept in combination with alemtuzumab induction and calcineurin inhibitor and corticosteroid withdrawal.

Detailed description: This is a single center, investigator initiated, pilot study to assess the safety and efficacy of Alefacept in combination with Alemtuzumab induction and Myfortic with rapid steroid and calcineurin inhibitor withdrawal in de novo Kidney transplant recipients. Induction therapy involves single dose Alemtuzumab and steroids peri-operatively. Tacrolimus will be administered for the first 30 days post-transplantation. Alefacept will be administered IV for the first two doses followed by subcutaneous injections weekly until 12 weeks post-transplant followed by monthly injections for the rest of the duration of the study. The primary outcomes are safety and efficacy outcomes, including biopsy proven acute rejection episodes, infectious complications or other serious adverse events. Secondary outcomes include T-helper differentiation, cytokine production and T regulatory cell generation assessed by immune monitoring assays.

Eligibility criteria: Inclusion Criteria:

* Recipient of a kidney from a non-HLA identical related living donor, a non- related living donor, or deceased donor
* Recipient of a de novo kidney transplant
* ≥ 18 years of age
* Anticipated to receive first oral dose of tacrolimus within 48 hours of transplant procedure
* Female subjects of child bearing potential must have a negative urine or serum pregnancy test, and must agree to maintain effective birth control during the study

Healthy donor is eligible for the blood draw if:

* Institutional Review Board (IRB) approved written Informed Consent and Health Insurance Portability and Accountability Act (HIPAA) Authorization for U.S. sites, or equivalent privacy language as per national regulations, is obtained from subject prior to any study-related procedures
