CRADLE was a 36-month multicenter study in pediatric (≥1 to <18 years) kidney transplant recipients randomized at 4 to 6 weeks posttransplant to receive everolimus + reduced-exposure tacrolimus (EVR + rTAC; n = 52) with corticosteroid withdrawal at 6-month posttransplant or continue mycophenolate mofetil + standard-exposure TAC (MMF + sTAC; n = 54) with corticosteroids. The incidence of composite efficacy failure (biopsy-proven acute rejection [BPAR], graft loss, or death) at month 36 was 9.8% vs 9.6% (difference: 0.2%; 80% confidence interval: -7.3 to 7.7) for EVR + rTAC and MMF + sTAC, respectively, which was driven by BPARs. Graft loss was low (2.1% vs 3.8%) with no deaths. Mean estimated glomerular filtration rate at month 36 was comparable between groups (68.1 vs 67.3 mL/min/1.73 m ). Mean changes (z-score) in height (0.72 vs 0.39; P = .158) and weight (0.61 vs 0.82; P = .453) from randomization to month 36 were comparable, whereas growth in prepubertal patients on EVR + rTAC was better (P = .050) vs MMF + sTAC. The overall incidence of adverse events (AEs) and serious AEs was comparable between groups. Rejection was the leading AE for study drug discontinuation in the EVR + rTAC group. In conclusion, though AE-related study drug discontinuation was higher, an EVR + rTAC regimen represents an alternative treatment option that enables withdrawal of steroids as well as reduction of CNIs for pediatric kidney transplant recipients.

CRADLE 是一项为期 36 个月的多中心研究,纳入了 4 至 6 周龄的儿科(≥1 至<18 岁)肾移植受者,随机分组接受依维莫司+低剂量他克莫司(EVR+rTAC;n=52)联合 6 个月时停用皮质激素,或继续霉酚酸酯+标准剂量他克莫司(MMF+sTAC;n=54)联合皮质激素治疗。36 个月时复合疗效失败(经活检证实的急性排斥反应[BPAR]、移植物丢失或死亡)的发生率,EVR+rTAC 组为 9.8%,MMF+sTAC 组为 9.6%(差异:0.2%;80%置信区间:-7.3 至 7.7),疗效失败主要由 BPAR 导致。移植物丢失率较低(2.1%比 3.8%),无死亡病例。36 个月时两组间估算的肾小球滤过率相当(68.1 比 67.3 mL/min/1.73 m )。从随机分组到 36 个月时身高的平均变化(z 评分)(0.72 比 0.39;P=0.158)和体重的平均变化(0.61 比 0.82;P=0.453)相当,而 EVR+rTAC 组青春期前患者的生长情况更好(P=0.050)。两组间不良反应(AE)和严重 AE 的总发生率相当。EVR+rTAC 组因 AE 导致研究药物停药的比例更高。总之,EVR+rTAC 方案虽然 AE 相关的研究药物停药率较高,但为儿科肾移植受者提供了一种替代治疗选择,可同时停用皮质激素和减少 CNIs。ClinicalTrials.gov:NCT01544491。
