Background. Long-term use of corticosteroids is associated with considerable morbidity, including cardiovascular and metabolic adverse effects. Methods. This study evaluated the long-term efficacy and safety of two steroid-free regimens compared with a triple immunosuppressive therapy in renal transplant recipients. This was a 3-year follow-up to a 6-month, open-label, randomized, multicenter study. Results. Data from 3 years were available for 421 (93.3%) of 451 patients in the original intent-to-treat population (143 tacrolimus/basiliximab [Tac/Bas], 139 tacrolimus/mycophenolate mofetil [Tac/MMF], and 139 tacrolimus/MMF/ [less ▲]

Background: This multicenter phase II study in renal transplantation compared 3 concentration-controlled ranges of FK778 (manitimus) with mycophenolate mofetil (MMF) both given in combination with tacrolimus and corticosteroids. Methods: 364 patients were randomized to 12-month treatment: high-level FK778 group (H, N = 87) received 4x600mg/day (4 days) followed by 120 mg/day; mid-level FK778 group (M, N = 92) received 3x600mg/day (3 days) followed by 110 mg/day, low-level FK778 group (L, N = 92) received 2x600mg/day (2 days) followed by 100 mg/day, and control group received MMF 1 g/day (MMF, N = 93). After week 6, FK778 doses were adjusted to trough ranges of 75–125 μg/mL (H), 50–100 μg/mL (M) and 25–75 μg/mL (L). Tacrolimus and steroids were administered at the same dose in each of the 4 groups. Results: Biopsy proven acute rejection (BPAR) at 24 weeks, the primary study endpoint, was comparable in the L (22.8%) and MMF (17.2%) groups but higher in the H (34.5%) and M (29.3%) groups. BPAR at 12 months was comparable in the L (23.9%) and MMF (19.4%) groups but higher in the H (34.5%) and M (31.5%) groups. Graft and patient survival were lowest in the H group and renal function was poorest in the H and M groups. Premature study withdrawal was highest in the H group. Conclusions: Efficacy was similar between the low-level FK778 and MMF groups. Increased FK778 exposure was poorly tolerated and did not improve efficacy. [less ▲]
