BACKGROUND Natalizumab is a highly efficacious therapy for relapsing-remitting multiple sclerosis (RRMS). Patients who discontinue natalizumab may experience return of MS disease activity. OBJECTIVE The aim of this study was to analyze predictors of post-natalizumab disease activity return. METHODS The Tysabri® Observational Program (TOP) is an ongoing observational study of natalizumab-treated RRMS patients. Patients discontinuing natalizumab are encouraged to remain in TOP. RESULTS Analyses included 3221 TOP patients. After ⩾2 years on natalizumab, relapse risk was twice as high for patients who switched to an oral therapy (n = 660, hazard ratio (HR) = 2.18, p < 0.001) and three times as high for patients who switched to an injectable therapy (n = 95, HR = 3.02, p < 0.001) as for those who stayed on natalizumab (n = 2466). Relapse rates after switching remained below pre-natalizumab rates. In patients who switched to an oral therapy, higher relapse risk was predicted by longer washout time, more pre-natalizumab relapses, higher Expanded Disability Status Scale score at natalizumab initiation, and shorter natalizumab treatment duration. CONCLUSION Patients who stayed on natalizumab had better clinical outcomes than those who switched to an oral or injectable therapy after ⩾2 years on natalizumab. These results highlight modifiable risk factors for disease activity return (e.g. natalizumab treatment duration and washout duration) to consider when making treatment decisions.

在 Tysabri® 观察计划 (TOP) 中,2 年后停止那他珠单抗治疗的患者的临床结果

背景那他珠单抗是一种用于复发缓解型多发性硬化症(RRMS)的高效疗法。停用那他珠单抗的患者可能会经历 MS 疾病活动的恢复。目的 本研究的目的是分析 natalizumab 后疾病活动恢复的预测因素。方法 Tysabri® 观察计划 (TOP) 是一项针对接受那他珠单抗治疗的 RRMS 患者的持续观察性研究。鼓励停用那他珠单抗的患者保持 TOP。结果 分析包括 3221 名 TOP 患者。使用那他珠单抗 ⩾ 2 年后,转为口服治疗的患者的复发风险高两倍(n = 660,风险比 (HR) = 2.18,p < 0.001),转为注射剂的患者复发风险高出三倍治疗(n = 95,HR = 3.02,p < 0.001)对于那些继续使用那他珠单抗的患者(n = 2466)。转换后的复发率仍低于使用那他珠单抗之前的率。在改用口服治疗的患者中,更长的清除时间、更多的那他珠单抗前复发、更高的那他珠单抗开始时的扩展残疾状态量表评分和更短的那他珠单抗治疗持续时间预测了更高的复发风险。结论 继续使用那他珠单抗的患者比使用那他珠单抗 ⩾ 2 年后转为口服或注射治疗的患者具有更好的临床结果。这些结果突出了在做出治疗决定时要考虑的疾病活动恢复的可改变风险因素(例如那他珠单抗治疗持续时间和洗脱持续时间)。那他珠单抗开始时的扩展残疾状态量表得分更高,那他珠单抗治疗持续时间更短。结论 继续使用那他珠单抗的患者比使用那他珠单抗 ⩾ 2 年后转为口服或注射治疗的患者具有更好的临床结果。这些结果突出了在做出治疗决定时要考虑的疾病活动恢复的可改变风险因素(例如那他珠单抗治疗持续时间和洗脱持续时间)。那他珠单抗开始时的扩展残疾状态量表得分更高,那他珠单抗治疗持续时间更短。结论 继续使用那他珠单抗的患者比使用那他珠单抗 ⩾ 2 年后转为口服或注射治疗的患者具有更好的临床结果。这些结果突出了在做出治疗决定时要考虑的疾病活动恢复的可改变风险因素(例如那他珠单抗治疗持续时间和洗脱持续时间)。
