Purpose: TRANSFORM (NCT01950819) is the largest study conducted in de novo kidney transplant recipients (KTxRs) to evaluate the benefit of everolimus with reduced-dose calcineurin inhibitor (EVR+rCNI) compared to mycophenolate with standard-dose CNI (MPA+sCNI). Here, we present renal function outcomes.
Methods: In this 24-month (M), phase IV, multicenter, open-label study, adult KTxRs were randomized within 24 h of Tx to either EVR+rCNI (N=1022) or MPA+sCNI (N=1015) with induction (basiliximab or rabbit antithymocyte globulin) and steroids. Renal function assessments included eGFR (4-Variable Modification of Diet in Renal Disease) in intent-to-treat (ITT) and on-treatment populations and by donor and CNI types.
Results: Of 2037 patients, 1847 (90.7%) completed 12M study. Baseline characteristics were balanced between arms. At M12, 86.3% of patients in EVR+rCNI arm were within target EVR C0. At M12, 40.0% (TAC) and 47.6% (CsA) of patients were above target CNI C0 in EVR+rCNI arm, whereas 62.1% (TAC) and 71.6% (CsA) of patients had CNI C0 within target range in MPA+sCNI arm. Mean eGFR at M12 was comparable in EVR+rCNI vs MPA+sCNI arms in ITT (53.0 vs 54.4mL/min/1.73 m2) and on-treatment (57.4 vs 57.5mL/min/1.73 m2) patients (Table 1). Incidence of eGFR <50 mL/min/1.73 m2 was also comparable in EVR+rCNI vs MPA+sCNI arms (45.4% vs 42.2%). Mean urinary protein/creatinine ratio was 298.56 (EVR+rCNI) vs 233.8 mg/g (MPA+sCNI). Most patients (>85%) in both arms had mild proteinuria (30-<500 mg/g). With regard to donor type, eGFR was similar in EVR+rCNI and MPA+sCNI arms among patients receiving allograft from living (58.3 vs 58.5mL/min/1.73 m2) and deceased (47.7 vs 50.4mL/min/1.73 m2) donors. Mean eGFR was similar among subgroups receiving TAC and CsA in both arms.
Conclusion: In this largest study involving KTxRs, renal function outcomes were comparable between EVR-based and sCNI-based regimens in ITT population up to M12, regardless of donor and CNI types.
