Name
MR-06-001
Description

Eligibility criteria
Inclusion Criteria:
* Patient is the recipient of a cadervic or living donor renal transplant.
* Patient was 18 years of age at time of transplant.
* Patient is at least 6 months post-transplant.
* Patient has been on a cyclosporine-based immunosuppressive regimen since the transplant.
* Patient has a functioning allograft and a Cockcroft/Gault estimate of creatinine clearance \>or= 35 mL/min within four weeks prior to randomization.
* Patient or legal guardian has signed and dated an Institutional Review Board (IRB) approved informed consent document and is willing and able to follow study procedures.
* Females are not pregnant and agree to practice effective birth control while receiving immunosuppressant medication.
Exclusion Criteria:
* Patient is the recipient of a solid organ transplant other than the kidney.
* Patient experienced biopsy-confirmed, acute rejection, (Banff 97 criteria)within 3 months before randomization that required treatment, which is defined as antilymphocyte therapy, corticosteroids, or an increase in the number or dose of immunosuppressant medication.
* Patient has recurrence of primary renal disease, or de novo renal disease.
* Patient has a urine protein of \> 1.5g/24 hours or two successive urinalyses sent to and reported by the laboratory indicating albuminuria greater than 2+ within 6 months prior to enrollment.
* Patient has an estimated creatinine clearance \< 35 mL/min calculated using Cockcroft/Gault formula within four weeks prior to randomization.
* Patient has changed adjunctive immunosuppressant therapy within one month if randomization.
* Patient is pregnant or lactating.
* Patient is a known carrier of any of the HIV viruses.
* Patient has a known or suspected malignancy (except for treated squamous or basal cell skin cancers) \< 5 years before randomization or a history of post-transplant lymphoproliferative disease (PTLD).
* Patient has a known hypersensitivity to tacrolimus, or any of the excipients of the drug.
