BACKGROUND: Phase II trials of FTY720, a novel immunomodulator, have shown promise in preventing rejection with both standard and reduced cyclosporine exposure. This study was designed to confirm those findings. METHODS: This one-year, multicenter, randomized, phase III study in 696 de novo renal transplant patients comparedFTY720 5 mg plus reduced-dose cyclosporine (RDC) or FTY720 2.5 mg plus full-dose cyclosporine (FDC) with mycophenolate mofetil (MMF) plus FDC. All patients received concomitant corticosteroid therapy without antibody induction. The primary efficacy composite endpoint was the incidence of first treated biopsy-proven acute rejection (treated BPAR), graft loss, death or premature study discontinuation at month 12. RESULTS:FTY720 2.5 mg plus FDC was demonstrated to be non-inferior to MMF plus FDC as the primary efficacy endpoint (30.8% and 30.6%) was comparable. The FTY720 5 mg plus RDC treatment regimen was discontinued due to an increased incidence of acute rejection episodes (primary endpoint 43.3%). FTY720 was associated with significantly lower creatinine clearance with a mean difference at 12 months between FTY720 2.5 mg plus FDC and MMF plus FDC of 8 ml/min. CONCLUSIONS: While FTY720 2.5 mg plus FDC yielded similar efficacy to MMF plus FDC, the FTY720 5 mg plus RDC did not allow a 50% reduction in cyclosporine exposure. The associated lower creatinine clearance indicated that FTY720 combined with cyclosporine provided no benefit over standard care.
