The introduction of mycophenolate mofetil (MMF) represented a major advance in transplant medicine, although optimal use may be limited by gastrointestinal (GI) side-effects. An enteric-coated formulation of mycophenolate sodium (EC-MPS; myfortic®) has been developed with the aim of improving the upper GI tolerability of mycophenolic acid. Therapeutic equivalence of EC-MPS (720 mg b.i.d.) and MMF (1000 mg MMF b.i.d.), with concomitant cyclosporine microemulsion (Neoral®) and corticosteroids, was assessed in 423 de novo kidney transplant patients recruited to a 12-month, double-blind study. Efficacy failure (biopsy-proven acute rejection [BPAR], graft loss, death or loss to follow up) at 6 months (EC-MPS 25.8% vs. MMF 26. 2%; 95% CI: [-8.7, + 8.01) demonstrated therapeutic equivalence. At 12 months, the incidence of BPAR, graft loss or death was 26.3% and 28.1%, and of BPAR alone was 2 2.5% and 24.3% for EC-MPS and MMF, respectively. Among those with BPAR, the incidence of severe acute rejection was 2.1% with EC-MPS and 9.8% with MMF (p = ns). The safety profile and incidence of GI adverse events were similar for both groups. Within 12 months, 15.0% of EC-MPS patients and 19.5% of MMF patients required dose changes for GI adverse events (p = ns). Enteric-coated-MPS 720 mg b.i.d. is therapeutically equivalent to MMF 1000 mg b.i.d. with a comparable safety profile.
