阿斯利康新抗生素药物CAZ-AVI治疗并发性腹腔内感染临床三期研究获得圆满成功

2014-08-22 佚名 生物谷

阿斯利康公司最近宣布公司开发的新型抗生素CAZ-AVI(ceftazidime-avibactam)治疗并发性腹腔内感染(cIAI)的临床三期研究取得令人满意的结果。结果显示CAZ-AVI在治疗cIAI患者(包括由抗头孢他汀菌引起的cIAI)时,与美洛培南同样有效。 本次临床三期研究采用了RECLAIM-1和RECLAIM-2实验设计。CAZ-AVI的有效成分由治疗严重细菌感染的头孢他汀和新

阿斯利康公司最近宣布公司开发的新型抗生素CAZ-AVI(ceftazidime-avibactam)治疗并发性腹腔内感染(cIAI)的临床三期研究取得令人满意的结果。结果显示CAZ-AVI在治疗cIAI患者(包括由抗头孢他汀菌引起的cIAI)时,与美洛培南同样有效。

本次临床三期研究采用了RECLAIM-1和RECLAIM-2实验设计。CAZ-AVI的有效成分由治疗严重细菌感染的头孢他汀和新型β内酰胺酶抑制剂avibactam构成。CAZ-AVI中的avibactam可以保护头孢他汀不被抗药性菌分泌的β内酰胺酶所分解,从而保持对细菌的毒性。该抗生素主要用于治疗一系列具有抗药性的革兰氏阴性菌。本次临床研究同时评估了不同剂量的CAZ-AVI在临床中的效果与安全性。结果显示CAZ-AVI的临床药效与meropenem,随机分配的患者基本都在给药的28-35天内痊愈。同时其副作用并不高于meropenem,临床中CAZ-AVI表现出的副作用主要有腹泻、呕吐、恶心和发烧。

阿斯利康的研究人员对这一结果表示振奋,同时还透露目前CAZ-AVI针对尿路感染与医院性肺炎的研究也正在有条不紊的进行。

十几年前,由于利润下降以及抗生素品种多样,许多制药巨头包括阿斯利康都纷纷退出抗生素市场。然而最近几年,抗药性细菌在全球呈现井喷态势,使这些制药巨头和各国医药管理部门意识到了严重的危机和机遇,许多制药商纷纷重新回归这一市场,投入精力开发新型抗生素。
