Abstract

Background Recent studies suggest that the combination of tacrolimus (TAC) and everolimus (EVL) could become a viable option for use as standard maintenance immunosuppression in non−highly sensitized kidney transplant recipients. Methods We conducted a single-center, open-label, randomized pilot trial comparing two maintenance immunosuppression regimens in non−highly sensitized, adult, primary kidney transplant recipients: (TAC/EVL, Group A) vs our standard maintenance regimen of TAC plus enteric-coated mycophenolate mofetil (TAC/EC-MPS, Group B). In both treatment arms, dual induction therapy consisting of anti-thymocyte globulin (Thymoglobulin) and basiliximab was given. Early corticosteroid withdrawal (by 7–10 days posttransplantation) was also planned in both arms. There were 30 study participants, 15 per treatment arm. Results during the first 12 months posttransplantation are reported here. Results Between 1 month and 12 months posttransplantation, mean TAC trough levels ranged between 5 and 8 ng/mL in both arms. Mean trough EVL level in Group A ranged between 4 and 6 ng/mL, and mean EC-MPS dose in Group B ranged from 1440 mg at 1 month to 945 mg at 12 months. One patient in Group A vs three patients in Group B experienced a first biopsy-proven acute rejection during the first 12 months posttransplantation (P =.32). Four patients in each group experienced biopsy-proven chronic allograft injury (interstitial fibrosis/tubular atrophy) (P =.99). There was a slight trend toward more favorable renal function in Group A at months 1–3 posttransplantation (P =.06,.10, and.18 for estimated glomerular filtration rate, respectively). No graft failures or deaths were observed in either group during the first 12 months posttransplantation. Four patients in each group developed an infection during the first 12 months posttransplantation. Two patients in Group A developed new-onset diabetes after transplant during the 12-month follow-up period, vs no patients in Group B (P =.13). Conclusion TAC/EVL may be a viable alternative to TAC/EC-MPS for use as standard maintenance immunosuppression in non−highly sensitized kidney transplant recipients and should be given further consideration.
