ATHENA: wisdom and warfare in defining the role of de novo mTOR inhibition in kidney transplantation.

ATHENA, published in this edition of Kidney International, is the third contemporary, multicenter, randomized, controlled trial to compare de novo use of everolimus, calcineurin inhibitor, and steroids to our current standard of care, mycophenolate, tacrolimus, and steroids, in kidney transplant recipients. This commentary highlights the strengths and significant weaknesses of ATHENA. It then seeks to distill the key messages from the 3 trials, ATHENA, TRANSFORM, and US92, and considers the role of everolimus in kidney transplantation today. Ultimately, the 3 trials demonstrate that everolimus with reduced-concentration tacrolimus and steroids provide a viable alternative to our current standard of care.
