安进进携手盖茨基金会寻找埃博拉药物ZMapp生产新方法

2014-10-24 佚名 生物谷

制药巨头安进公司上周六宣布将和盖茨基金会等机构合作研究生产抗埃博拉病毒药物ZMapp的新方法。ZMapp是迄今为止在临床中被证明对抗埃博拉病毒效果最好候选药物之一。这种药物首先是由Mapp生物医药公司开发的,其药物活性成分来自于一种经过基因修饰的烟草植物。但是ZMapp的整个生产流程长达四到六个月,也使得这一药物的市场化进程严重受阻。 这也是盖茨基金会寻求加速埃博拉病毒特效药研发的另一个尝试,此

制药巨头安进公司上周六宣布将和盖茨基金会等机构合作研究生产抗埃博拉病毒药物ZMapp的新方法。ZMapp是迄今为止在临床中被证明对抗埃博拉病毒效果最好候选药物之一。这种药物首先是由Mapp生物医药公司开发的,其药物活性成分来自于一种经过基因修饰的烟草植物。但是ZMapp的整个生产流程长达四到六个月,也使得这一药物的市场化进程严重受阻。

这也是盖茨基金会寻求加速埃博拉病毒特效药研发的另一个尝试,此前盖茨基金会已经向Mapp生物医药公司赞助了15万美元用于帮助公司寻找进一步加快ZMapp生产的新方法。而此次,安进公司则将尝试利用仓鼠卵巢细胞来生产这种药物的有效成分。尽管这一方法比现今医药生产所常用的方法慢了不少,但比Mapp此前的生产流程有了明显提速。

与此同时美国卫生部下属的生物医学高级研究和发展管理局(BARDA)在另一份独立的声明中表示将推动政府2012年新建的三个实验室来研发相关技术并投入四亿多美元扩大这种转基因烟草植物的产量和加工能力。而这三个实验室分别与葛兰素史克公司、诺华公司等制药巨头有紧密合作关系。这也将进一步加强生物医药企业和政府紧密配合应对突发疾病疫情的响应速度。

另一方面,由于采取措施及时得当,尼日利亚已经于上周被WHO从埃博拉疫情重灾区名单清除,这或许表明埃博拉疫情的蔓延趋势在一些地区已经得到初步遏制。(相关阅读:WHO宣布尼日利亚埃博拉疫情结束)但是如果要彻底消灭此次疫情,还需要国际社会的通力合作。

Lancet:埃博拉药物的临床试验不得不考虑伦理问题

生物伦理学家 Ezekiel Emanuel教授讲述关键的伦理原则,就是如果试验性药物在埃博拉疫情爆发后使用,要说明患者选择接受这些药物不能仅限于富裕或人脉广泛的病人,包括卫生保健专业人士。他们还指出,鉴于有限的实验性药物及其成功的可能性很低,应该优先在受影响的区域进行控制疫情和加强公共卫生等措施。 此外,至关重要的是实验药物要提供给随机对照试验的患者。说,与当地社区和其他利益攸关方进行合作
