Everolimus is a proliferation inhibitor designed to target chronic rejection, including prevention of acute rejection. Everolimus blocks growth factor-mediated transduction signals, preventing organ rejection by a mechanism different than that of calcineurin inhibitors and of mycophenolate mofetil (MMF). METHODS.: Everolimus (1.5 mg or 3 mg daily) was compared with MMF (2 g daily) in a randomized, multicenter, multinational, 12-month double-blind, double-dummy and 2-year open-label, phase 3 trial in de novo renal allograft recipients (n = 588) who also received cyclosporine and corticosteroids as part of a triple immunosuppressive regimen.
At 12 months, there were no statistically significant differences between doses of 1.5 and 3 mg/day everolimus and MMF (2 g/day) in incidence of biopsy-proven acute rejection (23.2%, 19.7%, and 24.0%, respectively), graft loss (4.6%, 10.6%, and 9.2%), or death (5.2%, 4.0%, and 2.6%), respectively. Everolimus 1.5 mg/day and MMF were generally equally well tolerated. Both were better tolerated than everolimus 3 mg/day. The incidence of cytomegalovirus infection was significantly lower in patients receiving either 1.5 or 3 mg/day everolimus than in those receiving MMF (5.2% and 7.6% vs. 19.4%, respectively) (P = .001).
Everolimus is effective in preventing acute rejection and graft loss in de novo renal allograft recipients receiving a triple immunosuppressive regimen. Prevention of acute rejection, along with reduction in cytomegalovirus infection, addresses two factors known to contribute to chronic rejection in such patients.
依维莫司是一种增殖抑制剂,旨在针对慢性排斥反应,包括预防急性排斥反应。依维莫司可阻断生长因子介导的转导信号,通过与钙调神经磷酸酶抑制剂和霉酚酸酯(MMF)不同的机制预防器官排斥反应。
在一项随机、多中心、跨国、为期12个月的双盲、双模拟以及2年开放标签的3期试验中,将依维莫司(每日1.5毫克或3毫克)与MMF(每日2克)进行比较,试验对象为初发肾移植受者(n = 588),这些受者同时接受环孢素和皮质类固醇作为三联免疫抑制方案的一部分。
在12个月时,每日1.5毫克和3毫克剂量的依维莫司与MMF(每日2克)在活检证实的急性排斥反应发生率(分别为23.2%、19.7%和24.0%)、移植肾丢失率(分别为4.6%、10.6%和9.2%)或死亡率(分别为5.2%、4.0%和2.6%)方面,均无统计学显著差异。每日1.5毫克依维莫司和MMF的耐受性总体相当。两者的耐受性均优于每日3毫克依维莫司。接受每日1.5毫克或3毫克依维莫司治疗的患者巨细胞病毒感染发生率显著低于接受MMF治疗的患者(分别为5.2%和7.6% vs. 19.4%)(P = .001)。
依维莫司在接受三联免疫抑制方案的初发肾移植受者中,对预防急性排斥反应和移植肾丢失有效。预防急性排斥反应以及降低巨细胞病毒感染,解决了已知导致此类患者慢性排斥反应的两个因素。
