ABSTRACT: We initially performed a study to evaluate the safety and efficacy of modified-release tacrolimus (FK506E) in a phase 3, 2-arm, 6-month, randomized, open-label, multicenter trial in Korean living donor de novo kidney transplant recipients. We then performed an extended study to evaluate the long-term safety and efficacy of a FK506E-based regimen up to 45 months posttransplantation in recipients already treated with FK506E. Initial study was designed as a randomized, open-label, comparative, multicenter study in de novo living donor kidney transplant recipients. The patients were randomized to an FK506E versus a control (FK506) group (1:1). Recipients who completed a 6-month FK506E treatment study were enrolled in the 39-month follow-up study. Primary end-points were patient and graft survivals at posttransplantation 45 months. Secondary end-point was the incidence of a clinical or biopsy-proven acute rejection episode between 6 and 45 months posttransplantation. In the initial 6-month de novo study 124 enrolled patients were randomized into either the FK506E (n = 62) or the control group (n = 62). The incidence of an acute rejection episode was 19.4% (n = 12) in the FK506E versus 16.1% (n = 10) in the control group (P = .638). There was no mortality or graft failure among the 44 recipients enrolled in this additional 39-month follow-up study. There was 1 patient with biopsy-proven acute cellular rejection episode (2.3%) who underwent steroid pulse therapy with renal function recovery. At the time of study completion 40/44 recipients (90.9%) maintained FK506E treatment. This 39-month study following the initial 6-month FK506E study period showed an FK506E-based immunosuppressive regimen in living donor kidney transplantation recipients to be safe and effective.Transplantation Proceedings 01/2012; 44(1):115-7. · 1.00 Impact Factor -
Article: A 6-month, multicenter, single-arm pilot study to evaluate the efficacy and safety of generic tacrolimus (TacroBell) after primary renal transplantation.

ABSTRACT: Tacrolimus has been shown to be an important immunosuppressive agent in organ and bone marrow transplantation. Previously, we reported that there were no statistically significant differences between the pharmacokinetic parameters of the oral formulation of generic tacrolimus (TacroBell) and the conventional formulation (Prograf). This study was designed to evaluate the efficacy and safety of oral capsules of TacroBell in de novo renal transplantation. Ninety-six renal transplant recipients from 9 transplantation centers in South Korea were enrolled between November 2005 and July 2007. De novo renal recipients ranged from 19-65 years old. Ninety-four patients who underwent renal transplantation were administered study drug at least one time in the intent-to-treat (ITT) analysis. This phase 4 clinical trial was a 26-week, open-label, noncomparative, multicenter study. An acute rejection episode developed in 10/94 recipients (10.6%, 95% confidence interval, 4.4%-16.9%). There were no patient deaths during the study. The 6-month graft survival rate was 96.8%. Based on this study, treatment with TacroBell is considered to be efficient and safe after primary renal transplantation.Transplantation Proceedings 07/2009; 41(5):1671-4. · 1.00 Impact Factor
