FDA批准了基于噬菌体治疗多药耐药感染的1/2期临床研究

随着全球多药耐药(MDR)感染的不断发生,研究人员已开始使用噬菌体(仅感染细菌的病毒)来替代常规抗生素。

随着全球多药耐药(MDR)感染的不断发生,研究人员已开始使用噬菌体(仅感染细菌的病毒)来替代常规抗生素。从事该领域的Adaptive Phage Therapeutics公司刚刚获得FDA的批准,可以在严重MDR感染患者中评价其个性化噬菌体疗法。

约有165名患有复杂和慢性复发性尿路感染(UTI)的患者将被纳入研究,研究名为BEUTIFL。这是首个获得FDA批准使用噬菌体进行治疗的1/2期临床试验。

研究的重点在于大肠杆菌和肺炎克雷伯菌等特定细菌,它们是常见的UTI病原体,容易发生MDR。研究的主要目标是根据疾病控制率确定理想的噬菌体治疗方案,并检测一年的安全性以及UTI复发率。

该试验的基础是APT技术平台,该平台可快速识别对细菌有效的新噬菌体(即使细菌突变为新菌株),同时可以对患者的特定细菌感染进行快速自动化的测试,并在APT的PhageBank库中找到匹配的噬菌体候选物。

2016年3月,APT的方法被用作Tom Patterson的实验性抢救疗法,Tom Patterson是感染了鲍曼不动杆菌(Acinetobacter baumannii)的重病患者,他是美国第一位成功接受静脉噬菌体治疗的患者,此后,其他几例患者接受了APT治疗。
