Mycophenolate mofetil has proven efficacy in the prophylaxis of acute rejection in solid organ transplantation; however, gastrointestinal intolerance can risk this efficacy because of associated dose adjustments and discontinued treatment. Enteric-coated mycophenolate sodium has demonstrated improved gastrointestinal tolerability, but the data in Asian subjects are scarce.


This was a Phase-IIIb, open-label, single-arm, multicentre, prospective 6-month study which investigated safety and graft function in stable maintenance renal transplant recipients of Asian origin, after switching from mycophenolate mofetil to enteric-coated mycophenolate sodium at least 3 months after transplantation. Primary end-points included renal allograft function and safety parameters.


The study recruited patients from 16 centres in Asian countries. The intention-to-treat and safety populations both included 122 patients. Graft function remained stable over the course of the study as measured by creatinine clearance and glomerular filtration rate. At 6 months the incidence of any gastrointestinal adverse events was 20.5% (n = 25), none of which required dose adjustments. There were only three cases of biopsy proven acute rejection with no reports of graft loss or death.


This study demonstrated that enteric-coated mycophenolate sodium is a safe and effective alternative to mycophenolate mofetil in Asian kidney transplant recipients.
