Inclusion criteria

* End stage kidney disease and a suitable candidate for primary renal transplantation or re-transplantation (unless the graft was lost from rejection within 12 months) * Receiving a kidney transplant from a cadaveric or living (non HLA identical) donor with compatible ABO blood type * Female subject of childbearing potential must have a negative serum pregnancy test at enrollment and must agree to maintain effective birth control during the study

Exclusion criteria

* Receiving or having previously received an organ transplant other than a kidney * Cold ischemia time of the donor kidney \> 30 hours * Receiving a graft from a non-heart-beating donor other than of Maastricht category 3 (withdrawn of support awaiting cardiac arrest) * Significant liver disease, defined as having continuously elevated SGPT/ALT and/or SGOT/AST and/or total bilirubin levels ≥ 2 times the upper value of the normal range of the investigational site or is receiving a graft from a hepatitis C or B positive donor * Requiring initial sequential or parallel therapy with immunosuppressive antibody preparation(s) * Requiring ongoing dosing with a systemic immunosuppressive drug prior to transplantation. * Significant, uncontrolled concomitant infections and/or severe diarrhea, vomiting, active upper gastro-intestinal tract malabsorption or active peptic ulcer * Pregnant woman or breast-feeding mother * Subject or donor known to be HIV positive * Known allergy or intolerance to tacrolimus, macrolide antibiotics, corticosteroids, basiliximab or mycophenolate mofetil or any of the product excipients * Diagnosis of new-onset malignancy prior to transplantation, with the exception of basocellular or squamous cell carcinoma of the skin which had been treated successfully * Currently participating in another clinical trial, and/or has taken an investigational drug within 28 days prior to enrollment * Any form of substance abuse, psychiatric disorder or condition which, in the opinion of the investigator, may complicate communication with the investigator
