The Mycophenolate Steroid Sparing (MYSS) study demonstrated that, in the setting of a maintenance immunosuppressive regimen without steroids, mycophenolate mofetil (MMF) and azathioprine (AZA) provided the same efficacy in preventing acute rejection episodes and allograft dysfunction in kidney transplant recipients. Induction therapy with basiliximab combined with low-dose thymoglobulin (RATG), through a transient depletion/inhibition of T lymphocytes, allows further reducing the need for maintenance immunosuppression.
