Abstract
Enteric-coated mycophenolate sodium (EC-MPS) is designed to reduce mycophenolate acid (MPA)-related upper gastrointestinal (GI) adverse events (AEs). A multicenter, open-label, Latin American study in stable renal transplant patients is ongoing to assess the safety of the conversion from mycophenolate mofetil (MMF) to EC-MPS. An interim analysis was performed when 93 patients had completed 3 months. Prior to conversion, they had received MMF at a dose of 2 g/d, with the exception of eight adult patients who were receiving an average daily dose of 1.25 g. All adult patients were converted to EC-MPS (1.44 g/d; 0.450 g/m(2) bid for children). After conversion, the reported total incidence of AEs was 40.9%, including 28% infections, 1.1% hematologic, 19.4% GI, including 10.8% upper-GI AE (all mild) and 5.4% diarrhea. No patient discontinued the study medication due to adverse events. Only six patients (6%) required a dose adjustment. There were no episodes of acute rejection, death, or graft loss. During the period of analysis, the conversion from MMF to EC-MPS was safe, the enteric-coated tablet formulation prevented release of MPA in the upper GI tract, and only one patient had to reduce the dose due to an upper GI AE, concomitant with diarrhea. EC-MPS offers transplant physicians and their patients an alternative MPA therapy that is as effective and safe as MMF, but in a formulation that may provide GI tolerability benefits.
