研究目的:

本研究旨在评估血浆置换序贯艾加莫德治疗全身型重症肌无力患者的疗效与安全性,特别是在改善MG-ADL和QMG评分、延缓疾病恶化及减少依赖免疫抑制剂方面的效果。研究还将探索与单独使用血浆置换或单独使用艾加莫德治疗的临床效果差异。  

Objectives of Study:

The objective of this study is to evaluate the efficacy and safety of sequential Efgartigimod following plasma exchange in patients with generalized myasthenia gravis, specifically in terms of improving MG-ADL and QMG scores, delaying disease progression, and reducing reliance on immunosuppressive therapies. The study will also compare clinical outcomes with plasma exchange alone or Efgartigimod alone.

本研究前期将采用纸质病例报告表(CRF)进行数据采集,后续将使用电子数据采集系统(EDC,网址:https://x-med.dazd.cn/),以保障数据的规范管理。所有数据录入和管理将由研究团队指定人员完成,在试验结束6个月内上传试验数据,确保数据的真实性、完整性和可追溯性。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

In the initial phase of this study, data will be collected using paper-based Case Report Forms (CRFs). Subsequently, an Electronic Data Capture (EDC) system (website: https://x-med.dazd.cn/) will be implemented to ensure standardized data management. All data entry and administration will be conducted by designated personnel from the research team, with trial data uploaded within 6 months after study completion to ensure authenticity, integrity, and traceability.
