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:
正在通过使用反义寡核苷酸(AON)sepofarsen治疗来探索由于CEP290纤毛病引起的Leber先天性黑蒙。一名患者是一个更大的队列(ClinicalTrials.govNCT03140969)的一部分,在单次玻璃体内注射sepofarsen后进行了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3个月左右达到了实质性的疗效峰值。15个月时,有持续的疗效,即使有证据表明从峰值反应减少。功效动力学可以通过AON驱动的新CEP290蛋白合成的平衡和人中央凹锥体光感受器中CEP290蛋白降解的缓慢自然速率来解释。
