Cyclosporine (CsA), dosed to achieve C2 targets, has been shown to provide safe and efficacious immunosuppression when used with a mycophenolate and steroids for de novo kidney transplant recipients. This study examined whether use of enteric-coated mycophenolate sodium (EC-MPS) together with basiliximab and steroids would enable use of CsA dosed to reduced C2 targets in order to achieve improved graft function.
Twelve-month, prospective, randomized, open-label trial in de novo kidney transplant recipients in Australia. Seventy-five patients were randomized to receive either usual exposure (n = 33) or reduced exposure (n = 42) CsA, EC-MPS 720 mg twice daily, basiliximab and corticosteroids.
There was no significant difference in mean Cockcroft-Gault CrCl (creatinine clearance) (60.2 ± 17.6 mL/min per 1.73 m(2) vs 63.2 ± 24.3, P = 0.64 for usual versus reduced exposure respectively) at 6 months. There was no significant difference between treatment groups in the incidence of treatment failure defined as biopsy proven acute rejection, graft loss or death (secondary endpoint: 30.3% full exposure vs 35.7% reduced exposure). At 12 months the incidence of overall adverse events was the same in both groups.
This exploratory study suggests de novo renal transplant patients can safely receive a treatment regimen of either full or reduced exposure CsA in combination with EC-MPS, corticosteroids and basiliximab, with no apparent difference in efficacy or graft function during the first year after transplant.
环孢素(CsA)在与吗替麦考酚酯和类固醇联合用于新诊断的肾移植受者时,以实现 C2 目标的剂量给药,已被证明可提供安全有效的免疫抑制作用。本研究检查了在使用依库珠单抗和类固醇的情况下,是否可以使用肠溶性吗替麦考酚酯钠(EC-MPS)与 CsA 联合使用,以实现降低 C2 目标的剂量,从而改善移植物功能。
在澳大利亚进行的一项为期 12 个月的前瞻性、随机、开放性试验,纳入新诊断的肾移植受者。75 例患者被随机分为常规剂量组(n=33)或低剂量组(n=42),分别接受常规剂量或低剂量 CsA、EC-MPS 720mg 每日 2 次、依库珠单抗和皮质类固醇治疗。
6 个月时,平均 Cockcroft-Gault CrCl(肌酐清除率)(60.2±17.6mL/min/1.73m² 与 63.2±24.3,常规剂量组与低剂量组分别为 P=0.64)无显著差异。治疗失败的发生率(定义为活检证实的急性排斥反应、移植物丢失或死亡)在两组之间无显著差异(次要终点:完全暴露组为 30.3%,低暴露组为 35.7%)。12 个月时,两组的总体不良事件发生率相同。
这项探索性研究表明,新诊断的肾移植患者可以安全地接受全剂量或低剂量 CsA 联合 EC-MPS、皮质类固醇和依库珠单抗的治疗方案,在移植后第一年,疗效和移植物功能无明显差异。
