Efficacy and safety of tacrolimus compared with cyclosporine microemulsion in primary simultaneous pancreas-kidney transplantation: 1-year results of a large multicenter trial
Background. Simultaneous pancreas-kidney transplantation (SPK) transplantation has become an accepted therapy for type 1 diabetic patients with endstage renal disease. This open-label, multicenter study compared the efficacy and safety of tacrolimus with the microemulsion (ME) formulation of cyclosporine in a clinical setting. The 1-year results are reported here. Methods. The study was conducted in 10 European centers and one center in Israel. One hundred three patients were randomly assigned to tacrolimus and 102 to cyclosporine-ME. All patients received concomitant rabbit anti-T-cell globulin induction therapy, mycophenolate mofetil (MMF), and short-term corticosteroids. The initial daily oral doses were 0.2 mg/kg for tacrolimus, 7 mg/kg for cyclosporine-ME, and 2 to 3 g for MMF. Results. The 1-year incidence of biopsy-proven kidney or pancreas acute rejection was lower with tacrolimus (27.2%) than with cyclosporine-ME (38.2%; P=0.09). Pancreas graft survival at 1 year was 91.3% with tacrolimus and 74.5% with cyclosporine-ME (P < 0.0005). Renal graft survival was similar in the two study groups. There were no significant treatment-related differences in pancreatic or renal graft function. In total, 34 patients switched treatment from cyclosporine-ME to tacrolimus, but only 6 patients receiving tacrolimus required alternative therapy. Mean doses of MMF at I year were also lower in the tacrolimus group (1.36 vs. 1.67 g/day; P=0.007). Conclusion. These findings support the use of tacrolimus therapy for uremic patients with type 1 diabetes who are undergoing SPK transplantation.
