Prospective, randomised study: Effect of mycophenolatmofetil (MMF) and CNI withdrawal in patients with histologically proven chronic allograft nephropathy Indication: change in immunosuppressive treatment of chronic allograft nephropathy (CAN)after renal transplantation Hypothesis: Antimetabolite MMF is able to stop progression of CAN and improve blood pressure/ metabolic parameters and structural vessel wall changes

Primary Target:effects of CNI withdrawal and MMF on renal function: stabilisation and/or improvement Secondary Targets: Incidence of adverse events Evaluation of the calcineurin inhibitor free MMF treatment effects on blood pressure, lipids, glucose metabolism and on structural and functional vesselwallchanges Method:open prospective, randomized two-tailed, monocentric study

Condition Intervention
Immunosuppressive Agents Kidney Failure, Chronic Kidney Transplantation Drug: mycophenolate mofetil (drug)

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Randomized Controlled Study: Effect of Mycophenolatmofetil in Patients With Histologically Proven Chronic Allograft Nephropathy
