应对碳青霉烯类耐药性,头孢吡肟联合taniborbactam取得积极结果

制药公司Venatorx近日宣布了一项 III 期研究(CERTAIN-1 试验)的积极结果,该研究旨在探索头孢吡肟联合taniborbactam治疗复杂尿路感染 (cUTI) 的有效性和安全性。

制药公司Venatorx近日宣布了一项 III 期研究(CERTAIN-1 试验)的积极结果,该研究旨在探索头孢吡肟联合taniborbactam治疗复杂尿路感染 (cUTI) 的有效性和安全性。CERTAIN-1试验表明,头孢吡肟联合taniborbactam 可能比标准护理提供“显著改善”。

CERTAIN-1招募了661例患有cUTI的成年患者,包括急性肾盂肾炎,他们被随机分配接受头孢吡肟联合taniborbactam或美罗培南治疗1周,如果他们患有菌血症,则接受长达2周。

Venatorx表示,头孢吡肟联合taniborbactam达到了统计上不劣于美罗培南的主要疗效终点,在实验治疗组中70%的患者发生了复合微生物学和临床成功,而美罗培南组患者为58%。该公司指出,头孢吡肟联合taniborbactam在预先指定的测试中也显示出复合终点的统计优势,并且这种优势在第28天至第35天的后期随访中持续存在。

同时,头孢吡肟联合taniborbactam组的治疗相关不良事件(TEAE)发生率为35.5%,美罗培南组为29%,而严重的TEAE分别发生在2%和1.8%的患者中。联合治疗组的停药率更高,为3%,而美罗培南的停药率略低于1%。头孢吡肟联合taniborbactam 组有1人死亡,但这被认为与治疗无关。

头孢吡肟是第四代头孢菌素,是一种广泛使用的β-内酰胺类抗生素,可对抗革兰氏阴性和革兰氏阳性菌;taniborbactam,也称为VNRX-5133,是一种新型广谱β-内酰胺酶抑制剂。当一起使用时,Venatorx认为它可以有效对抗由耐药革兰氏阴性菌引起的感染,特别是耐碳青霉烯类肠杆菌 (CRE) 和耐碳青霉烯类铜绿假单胞菌 (CRPA)。
