[全球医生组织北京代表处]|资讯|“人民的希望”瑞德西韦正式获FDA紧急授权应用

5月1日 , 美国FDA根据“紧急授权应用”(EUA)条款 , 正式批准了吉利德公司研制的抗病毒药“瑞姆西韦”用于治疗新冠病毒Covid-19感染患者(包括成人和儿童) 。
正如业界专家评述“这是板上钉钉的事儿了” 。
无论如何 , 该药的安全性至少比羟氯喹要好得多 。 羟氯喹是上市用药 , 临床治疗疟疾或风湿性关节炎等 , 但用于治疗新冠肺炎或Covid-19感染患者总是让人心里不踏实 。
然而 ,, 这其中的客观原因是什么?
WHO有关负责人也对此药的临床疗效 , 或可否应用于治疗新冠肺炎/Covid-19病毒感染给出了不知可否的答复 。
简单讲 , 同样规范的临床试验设计(随机、双盲安慰剂对照) , 如果临床疗效评估终点指标和该药应用紧急状况(目前疫情急迫窘况)不同 , 也可能最终左右了FDA审评专家给出了【绿灯】“紧急授权应用” 。
