- 这项研究评估了OCR对MS疾病活性,免疫球蛋白水平,淋巴细胞子集和感染的长期影响.
研究的目的:
- 评估ocrelizumab (OCR) 在复发性缓解性,初级渐进性和二级渐进性多发性硬化症患者的长期疗效.
- 评估OCR对免疫球蛋白水平,淋巴细胞子集和感染率在延长后续期的影响.
主要方法:
- 对140名多发性硬化患者,经过≥2年的OCR治疗进行了回顾性分析.
- 评估残疾恶化,复发率,MRI活动,免疫球蛋白水平 (IgG,IgM,IgA) 和淋巴细胞子集 (T CD4 +,T CD8 +,NK细胞).
- 通过使用多变量Cox模型,研究感染的发生,类型和结果.
主要成果:
- OCR显著减少了年复发率从0.61到0.02,持续没有复发和MRI活动.

Clinical Trials: Overview
Clinical development focuses on how the drug will interact with the human body and encompasses four key phases of clinical trials, each serving a specific purpose in assessing the safety and effectiveness of new drugs. These phases overlap and build upon one another. Phase I involves a small group of healthy volunteers (typically 20-80 individuals) or, in cases where significant toxicity is expected, patients with the targeted disease, such as cancer or AIDS. The volunteers are tested for...
Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents
Crohn's disease is an inflammatory bowel disorder marked by chronic inflammation of the GI tract. Various treatment strategies for Crohn's disease are employed, such as immunomodulatory agents, glucocorticoids, and biologics or anti-TNF therapy. Azathioprine (Imuran), a commonly used immunomodulatory drug for Crohn's disease, is converted in the body to mercaptopurine, which inhibits purine biosynthesis and cell proliferation. Both are utilized in severe cases of Inflammatory Bowel Disease...
