研究目的:

1. 构建并内部验证一个适用于婴幼儿肝移植术后早期的TAC PopPK/PD-ML融合预测模型; 2. 通过多中心随机对照研究,评估该融合模型引导的给药策略在实现目标浓度快速达标方面的有效性及安全性; 3. 探索新策略对术后1年内的临床硬终点(如急性排斥反应、移植物失功、患者死亡等)的潜在改善作用。  

Objectives of Study:

1. To develop and internally validate a PopPK/PD-ML integrated predictive model for early postoperative tacrolimus therapy in infant liver transplant recipients. 2. To evaluate, through a multicenter randomized controlled trial, the efficacy and safety of the integrated model-guided dosing strategy in achieving rapid target concentration attainment. 3. To explore the potential improvement of the novel strategy on one-year clinical hard endpoints (e.g., acute rejection, graft loss, patient death).

排除标准:

1. 接受多器官联合移植(如肝肾联合移植); 2. 术后早期(3个月内)因严重并发症导致移植物无功能或需再次移植; 3. 对TAC或相关辅料过敏; 4. 监护人拒绝参与研究,或因个人原因无法配合随访、数据采集及用药记录。

Exclusion criteria:

1.Having received multi-organ transplantation (e.g., combined liver-kidney transplantation); 2.Patients with graft failure or requirement for re-transplantation due to severe complications within 3 months postoperatively; 3.Hypersensitivity to TAC or its excipients; 4.Legal guardians who refuse to participate in the study or are unable/unwilling to comply with follow-up visits, data collection, or medication records due to personal reasons.
