|Official Title:||A MULTICENTER, SINGLE-ARM, OPEN, CONVERSION STUDY FROM A CYCLOSPORINE (CyA) BASED IMMUNOSUPPRESSIVE REGIMEN TO A TACROLIMUS MODIFIED RELEASE, FK506MR, BASED IMMUNOSUPPRESSIVE REGIMEN IN KIDNEY TRANSPLANT SUBJECTS|
- Change in creatinine clearance, calculated according to Cockcroft and Gault formula. [ Time Frame: Week 24 ] [ Designated as safety issue: No ]
- Change in creatinine clearance, calculated according to Cockcroft and Gault formula, between Baseline (Day 1) and week 24 (End of Study) overall [ Time Frame: Week 24 ] [ Designated as safety issue: No ]
- Rating of subjects according to reason for conversion: Changes in mean lipid levels (total cholesterol) [ Time Frame: Week 24 ] [ Designated as safety issue: No ]

Multicenter, single-arm, open phase IIIb, conversion study where a Cyclosporine A-based immunosuppressive regimen is replaced by the administration of tacrolimus modified release formulation, MR4, once daily (morning dosing only) in stable renal transplant subjects. The initial recommended dose of MR4 is 0.1 mg/kg/day.
Twenty-four weeks of treatment on MR4-based immunosuppressive regimen is considered to be an appropriate study duration in order to assess the response in subjects suffering from one or more known cyclosporine side effects, hypertrichosis/hirsutism, gingival hyperplasia, hyperlipidemia, arterial hypertension.
Stable, adult kidney transplant recipients (≥ 12 months post transplant) who are currently treated with cyclosporine and who meet the Inclusion and Exclusion Criteria will be enrolled.
