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). |

随机方法(请说明由何人用什么方法产生随机序列): |
随机序列将由与本试验结果无直接利益关系的独立生物统计师,使用计算机生成随机数字,采用区组随机化法(区组长度可变,对研究者隐蔽)生成。序列将按1:1比例分配至“模型引导给药组”与“传统给药组”。 |
||||||||
|
Randomization Procedure (please state who generates the random number sequence and by what method): |
The random sequence will be generated by an independent biostatistician with no direct interest in the trial outcomes, using computer-generated random numbers and the block randomization method (with varying block sizes, concealed from the investigators). The sequence will allocate participants at a 1:1 ratio to the "Model-Guided Dosing Group" and the "Conventional Dosing Group." |
