NEJM:Tofersen治疗SOD1-ALS

2020-07-09 MedSci原创 MedSci原创

在由 SOD1突变引起的ALS的成年人中,接受tofersen鞘内注射可降低脊髓液 SOD1浓度,部分患者出现脑脊液和细胞增多,大多数患者观察到腰椎穿刺相关的不良事件

反义寡核苷酸药物Tofersen可介导超氧化物歧化酶1(SOD1)信使RNA降解,减少SOD1蛋白合成。鞘内给药Tofersen可用于治疗SOD1突变引起的肌萎缩侧索硬化症(ALS)。
 
近日研究人员进行了一项1-2期递增剂量试验,以评估SOD1突变所致ALS患者接受tofersen的安全性和疗效。研究分为20、40、60或100毫克剂量组,参与者随机接受5个剂量的tofersen或安慰剂,鞘内给药12周。研究的主要结果是安全性和药代动力学。次要结果是第85天脑脊液(CSF)SOD1浓度变化。
 
50名参与者,在大多数参与者中观察到腰椎穿刺相关的不良事件。分别有4名和5名接受tofersen治疗的参与者出现脑脊液白细胞计数和蛋白升高。在接受tofersen治疗的参与者中,1名在第137天死于肺栓塞,另一名在第152天死于呼吸衰竭;安慰剂组的1名参与者在第52天死于呼吸衰竭。在第85天,tofersen组和安慰剂组的CSF SOD1浓度与基线相比的变化为:20mg剂量组为2%,40mg剂量组的差异为-25%,60mg剂量组的差异为-19%, 100mg剂量组的差异为的-33%。
