Despite the potential tolerability advantage of enteric-coated mycophenolate sodium (EC-MPS), no prospective, randomized trial has evaluated whether conversion from mycophenolate mofetil (MMF) to EC-MPS permits mycophenolic acid dose to be increased or gastrointestinal side-effects to be ameliorated. In a randomized, multicenter, open-label trial, kidney transplant recipients experiencing gastrointestinal side-effects either remained on MMF or switched to an equimolar dose of EC-MPS, adjusted 2 weeks subsequently to target the highest tolerated dose up to 1440 mg/day (EC-MPS) or 2000 mg/day (MMF). Patients were followed up to 12 weeks postrandomization. One hundred and thirty-four patients were randomized. The primary efficacy endpoint, the proportion of patients receiving a higher mycophenolic acid (MPA) dose at week 12 than at randomization, was significantly greater in the EC-MPS arm (32/68, 47.1%) than the MMF arm (10/61, 16.4%; P < 0.001). At the final visit, 50.0% (34/68) of EC-MPS patients were receiving the maximum recommended dose versus 26.2% (16/61) of MMF patients ( P = 0.007). Kidney transplant patients receiving reduced-dose MMF because of gastrointestinal side-effects can tolerate a significant increase in MPA dose after conversion to EC-MPS. Patient-reported gastrointestinal outcomes with higher doses of EC-MPS remained at least as good as in MMF-treated controls. [ABSTRACT FROM AUTHOR]
