NEJM:I型脊肌萎缩症的单剂量基因替换治疗

2017-11-02 zhangfan MedSci原创

研究认为,对于I型脊肌萎缩症患儿,接受运动神经元1基因治疗可延长患儿生存期并改善运动功能

I型脊肌萎缩症(SMA1)是一种渐进的、单基因运动神经元病。近日研究人员考察了运动神经元1 (SMN1)基因治疗的临床效果。

研究招募了15名患者,接受单剂量的9型腺病毒SMN基因治疗。3人接受低剂量治疗(6.7×1013 vg/kg),12人接受高剂量(2.0×1014 vg/kg)。研究的主要终点是安全性,次要终点是患者死亡以及永久性辅助通气时间。扩展分析中,研究人员比较了2个队列患儿的神经肌肉疾病测试评分(CHOP INTEND,0-64;得分越高,患者运动功能越好)以及运动能力事件里程碑差异。

至2017年8月7日,所有患者均存活,无疾病影响生存期为20个月,而历史队列患儿20个月的生存率仅为8%。高剂量组治疗后CHOP INTEND得分快速上升,1个月后的得分上升9.8分,3个月的得分上升15.4分,而历史队列研究同期得分显著下降。高剂量组12名患儿中,11人可独坐,9人可翻身,11人具有吞咽和语言功能,2人可独立行走。4名患儿出现血清转氨酶升高,使用强的松后得到有效控制。

研究认为,对于I型脊肌萎缩症患儿,接受运动神经元1基因治疗可延长患儿生存期并改善运动功能。
