新抗生素药物德拉沙星临床III期研究成功,上市在即

2016-05-14 MedSci MedSci原创

抗生素研究近年来经历了潮起潮落。上世纪九十年代,众多生物医药巨头由于各种各样的原因纷纷离开了这一领域。然而,时隔不到二十年,超级菌已经成为了世界各国健康部门所面临的巨大威胁。而新抗生素的研发却已经无法跟上细菌变异的脚步。最近,来自美国的Melinta公司在抗生素研发领域取得重要进展,有望缓解目前产业抗生素产品缺乏的现状。公司开发的新型抗生素药物德拉沙星---delafloxacin(Baxdela

抗生素研究近年来经历了潮起潮落。上世纪九十年代,众多生物医药巨头由于各种各样的原因纷纷离开了这一领域。然而,时隔不到二十年,超级菌已经成为了世界各国健康部门所面临的巨大威胁。而新抗生素的研发却已经无法跟上细菌变异的脚步。最近,来自美国的Melinta公司在抗生素研发领域取得重要进展,有望缓解目前产业抗生素产品缺乏的现状。公司开发的新型抗生素药物德拉沙星---delafloxacin(Baxdela)已经顺利完成了一项临床三期研究,有望在最近提交管理部门申请上市。

此次,Baxdela完成了用于治疗急性皮肤感染(ABSSSI)的临床三期研究。在此次研究中,研究人员证明了该药物与目前临床上vancomycin/aztreonam的标准疗法之间的非劣性比较。公司表示这一研究已经达到了FDA、EMA关于抗生素研究的相关要求。

为了实现这一目标,Melinta公司付出了长达16年的努力和大量的资金。这家前身为Rib-X的生物技术公司长期致力于开发新型抗生素研究。此前公司原本计划进行delafloxacin治疗淋病的相关研究,不过随后将研究方向转向了ABSSSI方面。

目前众多医药巨头离开抗生素研究领域。尽管默沙东公司在收购了Cubist之后计划重返这一领域,但公司很快就放弃了抗生素研究领域的早期研发工作。而Melinta则是目前这一领域的代表之一。目前临床上急需新型抗生素产品代替传统产品来治疗包括耐甲氧西林金黄色葡萄球菌在内的多种超级菌感染。

值得业界注意的是,此次临床研究中一半的患者都患有肥胖、糖尿病等疾病。这也侧面证明了Baxdela在治疗患有糖尿病等疾病的较难治愈患者方面的优势。
