2018-09-26 zhangfan MedSci原创

研究认为M72/AS01E对潜伏性结核感染的预防有效率为54%

近日研究人员公布了新型结核疫苗M72/AS01E的II期临床结果。

本次研究在非洲多国开展,HIV阴性的成年潜伏性结核病感染患者参与研究,随机接受2剂量的M72/AS01E或安慰剂。研究的主要终点为安全性以及对经细菌证实的活动性肺结核病发病。

研究平均随访2.3年,总计1786人接受疫苗,1787人接受安慰剂。疫苗组10名患者经细菌证实患活动性肺结核病,安慰剂组22人患病,每100随访年发病率分别为0.3例和0.6例。疫苗的有效率为54.0%。疫苗接种组67.4%的患者在30天内出现不良事件,主要是流感样症状,安慰剂组不良事件率为45.4%。

研究认为M72/AS01E对潜伏性结核感染预防有效率为54%。
