Aim: To compare safety and efficacy of 3 different immunosuppressive (IS) regimens 2years after renal transplantation (Tx).
Methods: 802 patients (pts) were included in this 1year, prospective, open-label, randomized (rdz), controlled, multi-center study. After induction therapy with basiliximab all pts received cyclosporine A (CsA), enteric-coated mycophenolate sodium (EC-MPS) +steroids. 3 months (Mo) post Tx 499pts were rdz 1:1:1 to either a) continue standard (STD) treatment CsA(100-180ng/ml) + EC-MPS(n=166), or convert b) to a calcineurin inhibitor (CNI)-free regimen with everolimus (EVE;5-10ng/ml) + EC-MPS(n=171) or c) to CNI-low regimen with EVE(3-8ng/ml) + reduced CsA(50-75ng/ml) (n=162). All pts continued on steroids. Mo24 follow-up (FU) visit was performed by 131(96%) STD, 132(96%) CNI-free and 125(93%) CNI-low regimen pts of the ongoing FU population (pop).
Results: From rdz to Mo24 BPAR was reported in 17/144(12%) STD, 20/146(14%) CNI-free and in 17/141(12%) CNI-low pts (ITT). 2 deaths (1%) occurred in the CNI-low, none in the other groups. 1(1%) graft loss was observed in the STD and 4(3%) in the CNI-free group. Composite failure (BPAR, death, graft loss, loss to FU) was measured in 19(13%) STD, 22(15%) CNI-free, 20(14%) CNI-low treated pts. Premature discontinuation due to adverse events occurred in 1/147(1%) of STD, 3/148(2%) of CNI-free and 1/141(1%) of CNI-low group pts (safety-pop) from Mo12-24. Renal function expressed as cGFR (Nankivell) was significantly improved by +4.8mL/min/1.73m2(95%CI:[+1.0;+8.6]) in favor of the CNI-free regimen at Mo24(ITT;p=0.014).
|Safety Pop. n(%) *||Standard||CNI-free||CNI-low|
|Infections||32 (21.8)||50 (33.8)||35 (24.8)|
|Severe infections||6 (4.1)||7 (4.7)||9 (6.4)|
|Infections with hospitalisation||21 (14.3)||32 (21.6)||28 (19.9)|
|CMV||4 (2.7)||4 (2.7)||2 (1.4)|
|BKV||1 (0.7)||2 (1.4)||2 (1.4)|
|Hospitalisation due to:|
|Acute rejection||9 (6.1)||10 (6.8)||8 (5.7)|
|Cardiovascular event||4 (2.7)||2 (1.4)||1 (0.7)|
|GI event||5 (3.4)||4 (2.7)||3 (2.1)|
|Malignancy||2 (1.4)||6 (4.1)||1 (0.7)|
|Metabolic disorder||2 (1.4)||0||0|
Conclusions: The 24Mo results from HERAKLES study showed that the IS regimens using EVE with low-dose or without CNI-exposure reflect an efficacious and safe therapeutic approach offering the opportunity for an individualized IS.
