About

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

Full 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.

Inclusion criteria

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, obtained from the subject or legally authorized representative prior to study-related procedures (including withdrawal of prohibited medication, if applicable)
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
Subject is a donor to a de novo kidney transplant subject who is enrolled in the study or a self declared healthy volunteer who is not a kidney donor for a subject enrolled in the study
≥ 18 years of age

Exclusion criteria

Previously received or is receiving an organ transplant other than a kidney
Sensitivity to iodine
Will receive a transplant from a non-heart beating donor (donation after cardiac death - DCD)
Receives a transplant from an HLA identical related living donor
Will receive a solitary kidney from a deceased donor < 5 years of age
Will receive a kidney with an anticipated cold ischemia time (CIT) of > 30 hours
Will receive an ABO incompatible donor kidney
Recipient or donor is known to be seropositive for human immunodeficiency virus (HIV)
Recipient has a positive T or B cell crossmatch by investigational site's standard method of determination. For recipients where a flow cytometry crossmatch is performed and is positive in either T or B cell testing, recipients are excluded only if donor specific, anti-HLA antibody is detected by flow cytometry based, specific anti-HLA antibody testing.

Serologically negative for Epstein Barr virus
Has received intravenous immunoglobulin (IVIG) therapy in the three months prior to first dose of study drug
Uncontrolled concomitant infection or any other unstable medical condition that could interfere with the study objectives
Concurrently participating in another drug study or has received an investigational drug within 28 days prior to transplant
Known hypersensitivity to alefacept, alemtuzumab, tacrolimus, mycophenolic acid, corticosteroids, or any of their components
Any form of substance abuse, psychiatric disorder, or a condition that in the opinion of the Investigator could invalidate communication with the Investigator
Subject is pregnant or lactating
Subject is unlikely to comply with the visits scheduled in the protocol
Subject will receive a kidney transplant from an expanded criteria donor (ECD)
Will receive a kidney transplant from a CDC high risk donor
