Alnylam/Vir宣布推进RNAi疗法VIR-2703,用于抵抗新冠病毒COVID-19

2020-05-06 MedSci原创 MedSci原创

RNAi疗法VIR-2703实现50%抑制(EC50)的有效浓度小于100 pM,而EC95有效浓度小于1 nM。

Alnylam Pharmaceuticals和Vir Biotechnology宣布,他们计划开发VIR-2703,这是一种针对SARS-CoV-2基因组的研究性RNAi疗法,可作为潜在治疗或预防COVID-19的有效药物。

据两家公司表示,Alnylam合成了数百个针对SARS-CoV-2基因组高度保守区域的小干扰RNA。在体外SARS-CoV-2病毒模型中,VIR-2703实现50%抑制(EC50)的有效浓度小于100 pM,而EC95有效浓度小于1 nM。

Alnylam首席执行官John Maraganore表示:"据我们所知,这是迄今为止报道的针对SARS-CoV-2最有效且直接作用的抗病毒药之一。"两家公司打算在年末前后启动VIR-2703针对SARS-CoV-2的临床试验。

上个月,葛兰素史克收购了Vir 公司2.5亿美元的股份,以合作开发针对新型冠状病毒的抗病毒抗体,最初的重点是VIR-7831和VIR-7832。
