The Cambridge Centre for Myelin Repair One (CCMR-One) trial showed that 6 months of bexarotene reduces visual evoked potential (VEP) latency in people with relapsing-remitting multiple sclerosis (MS). In a single-centre follow-up study of these participants, we re-examined full-field VEP and clinical assessments. Twenty participants (12 bexarotene and 8 placebo) were seen on average 27 months after their trial involvement. In an analysis of all eyes with recordable signal (24 bexarotene and 14 placebo), the adjusted bexarotene-placebo treatment difference in P100 latency was -7.79 (95% confidence interval (CI) = -14.76, -0.82) ms, = 0.044. We conclude that there were durable improvements in VEP latency, suggesting long-term benefits from exposure to a remyelinating drug.
剑桥髓鞘修复中心一号(CCMR-One)试验表明,6 个月的贝沙罗汀可降低复发缓解型多发性硬化症(MS)患者的视觉诱发电位(VEP)潜伏期。在这些参与者的一项单中心随访研究中,我们重新检查了全视野 VEP 和临床评估。在试验参与平均 27 个月后,20 名参与者(12 名接受贝沙罗汀治疗,8 名接受安慰剂治疗)接受了检查。在对所有可记录信号的眼睛(24 名接受贝沙罗汀治疗,14 名接受安慰剂治疗)进行分析后,调整后的贝沙罗汀与安慰剂治疗 P100 潜伏期差值为-7.79(95%置信区间(CI)为-14.76,-0.82)ms,=0.044。我们得出结论,VEP 潜伏期有持久改善,提示接触髓鞘修复药物有长期获益。
