TY -的T1 -减少复发活动对于那些开关Natalizumab替代疾病修饰治疗:一项观察性研究(P3.272) JF -神经学乔-神经学六世- 84 - 14补充SP P3.272 AU -罗伯特·麦奎因盟Terrie利文斯通非盟-盖Vollmer盟-约翰Corboy盟Nair盟的故事——乔纳森·坎贝尔Y1 - 201首页5/04/06 UR - //www.ez-admanager.com/content/84/14_Supplement/P3.272.abstract N2 -目的:检查开关的影响从疾病修饰治疗(儿童),如干扰素或glatiramer醋酸(GA),持久Natalizumab使用声明的复发率。二级目标检测的影响从持久natalizumab使用切换到其他与儿童在声明的复发率。背景:Natalizumab复发缓和多发性硬化(MS)表明可有效减少复发与其他儿童活动后切换。设计/方法:使用IMS PharMetrics +声称数据库(2006年- 2012年),我们发现那些女士发起natalizumab(没有natalizumab声称年之前),至少有两年的随访。坚持每年随访时间被定义为没有90天或更大的差距natalizumab疗法。复发是一个医学相关住院或门诊访问与静脉注射或口服类固醇突然要求7天内。分析比较患者的观察(例如,在主题)基于natalizumab持久性和开关状态的变化从一年到下一个(如过渡从natalizumab GA持久),折合成年率的复发率和估计的差异。结果:共有107名病人观察了儿童发展前一年;25 (23 [percnt])这些转变natalizumab持久性。 2,723 patient observations were persistent on natalizumab in the year prior; 267 (10[percnt]) of these switched to another DMT. Patient observations switching from alternative DMTs and transitioning to persistent natalizumab use were associated with a relapse-rate decrease of -0.44 (95[percnt] CI: -0.76, -0.13). Patient observations transitioning from persistent on natalizumab to alternative DMTs were associated with a relapse-rate increase of 0.34 (95[percnt] CI: 0.17, 0.52). CONCLUSIONS: Findings suggest those who transition from other DMTs to persistent on natalizumab have statistically significant reductions in annual relapse rates. Alternatively, real-world persistent natalizumab users who switch to another DMT have statistically significant increases in annual relapse rates.
