A 6-month, open-label, multicenter clinical study in Korean de novo renal transplant patients evaluating the efficacy, safety, and tolerance of myfortic concomitantly used with tacrolimus

Abstract

Enteric-coated mycophenolate sodium (myfortic, Novartis Pharma AG, Basel, Switzerland) is designed to improve the gastrointestinal tolerability of micophenolic acid. This study was designed to evaluate the efficacy and safety of myfortic in Korean de novo renal transplantation. A total of 65 patients from four transplantation centers received the study drug at least once and were included in the intention-to-treat analysis. This study was an open-label, single-arm, multicenter trial with 6-month patient follow-up. Patients received 360 mg (body weight < 50 kg) or 720 mg (body weight > 50 kg) of myfortic per day with tacrolimus and steroids. Induction therapy included basiliximab. The incidence of biopsy-confirmed acute rejection (primary endpoint) within 6 months after transplantation was 7/65 (10.8%). There were 2 (3.1%) graft losses due to severe acute rejection and 1 (1.5%) patient-death due to cardiac arrest. Twenty-two (38.8%) patients experienced gastrointestinal discomfort; however, only 3 (4.5%) cases were associated with an apparent drug reaction. Seventeen (25.4%) patients underwent dose adjustment or myfortic discontinuation during the study period. Patient and graft survival rates at 6 months posttransplantation were 98.1% and 97.0%. Myfortic with tacrolimus-based immunosuppression was efficient and safe after de novo renal transplantation in Korean patients.
