Abstract
Leber congenital amaurosis due to CEP290 ciliopathy is being explored by treatment with the antisense oligonucleotide (AON) sepofarsen. One patient who was part of a larger cohort (ClinicalTrials.gov NCT03140969 ) was studied for 15 months after a single intravitreal sepofarsen injection. Concordant measures of visual function and retinal structure reached a substantial efficacy peak near 3 months after injection. At 15 months, there was sustained efficacy, even though there was evidence of reduction from peak response. Efficacy kinetics can be explained by the balance of AON-driven new CEP290 protein synthesis and a slow natural rate of CEP290 protein degradation in human foveal cone photoreceptors.
摘要
正在探索使用反义寡核苷酸（AON）司泊法新治疗由CEP290纤毛病引起的莱伯先天性黑蒙。一名参与更大队列研究（ClinicalTrials.gov NCT03140969）的患者在单次玻璃体内注射司泊法新后接受了15个月的研究。视觉功能和视网膜结构的一致测量在注射后近3个月达到了显著的疗效峰值。在15个月时，尽管有证据表明从峰值反应有所下降，但仍有持续疗效。疗效动力学可以通过AON驱动的新CEP290蛋白合成与人类中央凹视锥光感受器中CEP290蛋白缓慢的自然降解率之间的平衡来解释。
