Study Arms:
- Calcineurin Inhibitor (CNI) group (Type: ACTIVE_COMPARATOR): Participants received Cyclosporine A (CsA) plus Enteric Coated Mycophenolate Sodium (EC-MPS) plus corticosteroids, or Tacrolimus A (CsA) plus Enteric Coated Mycophenolate Sodium (EC-MPS) plus corticosteroids.
- Certican group (Type: EXPERIMENTAL): Participants were switched in a step-wise fashion from the CNI based regimen to Everolimus (RAD001).
