研究目的: |
本研究旨在验证并应用一套融合凝血因子VIII (FVIII) 免疫应答规律与机器学习算法的免疫耐受诱导 (ITI) 个体化预测模型,以期实现儿童血友病A抑制物清除治疗的精准化。具体目的包括: 模型验证:通过回顾性队列研究,利用独立的外部数据对已构建的基于FVIII免疫应答“指数衰减模型”及机器学习算法的ITI个体化预测模型进行外部验证,评估其预测抑制物清除结局的准确性与稳健性。 临床应用与评估:开展前瞻性、单中心、单组目标值临床研究,将该预测模型应用于临床实践,指导ITI治疗方案的初始制定与动态调整(包括剂量选择及免疫抑制剂联用),并评估其在提高ITI成功率、缩短治疗时间、降低治疗成本以及改善患儿生活质量方面的临床有效性。 策略推广:最终建立一套可推广的儿童血友病A抑制物精准诊疗新策略,推动ITI治疗从“经验驱动”向“精准指导”转变,为卫生资源优化及其他罕见病管理提供科学依据。 |

Objectives of Study: |
This study aims to validate and implement an individualized prediction model for Immune Tolerance Induction (ITI) that integrates Factor VIII (FVIII) immune response patterns with machine learning algorithms, with the goal of achieving precision medicine in inhibitor eradication for pediatric Hemophilia A. The specific objectives are:Model Validation: To conduct a retrospective cohort study using independent external data to validate the previously constructed ITI individualized prediction model, which is based on the "exponential decay model" of FVIII immune response and machine learning algorithms, and to evaluate its accuracy and robustness in predicting inhibitor eradication outcomes.Clinical Application and Evaluation: To perform a prospective, single-center, single-arm objective performance criteria (OPC) clinical trial to apply this prediction model in clinical practice for guiding the initial formulation and dynamic adjustment of ITI treatment regimens (including dosage selection and the use of immunosuppressants). The study will assess the clinical effectiveness of the model in improving ITI success rates, shortening treatment duration, reducing treatment costs, and enhancing the quality of life for patients.Strategy Promotion: To establish a scalable, precision diagnosis and treatment strategy for inhibitor eradication in pediatric Hemophilia A. |
