這項為期兩年的2期臨床試驗納入了272名輕度至中度有阿爾茲海默病癥狀的患者,紐約時報報告說,禮來公司表示,,相比接收安慰劑治療的患者而言,通過每四周輸注這種實驗性藥物的患者智力下降的速度減緩了32%;當進行donanemab藥物6-12個月的治療后,患者機體不會再攜帶β淀粉樣蛋白斑塊,,這是阿爾茲海默病發(fā)病的標志。
然而,,該研究結果目前尚未被其他研究人員進行審查,,也并未以任何形式進行發(fā)表,該藥物的主要副作用在服用實驗性單克隆抗體來治療阿爾茲海默病的患者中非常常見,,即大腦中出現(xiàn)體液積累,,而且這種副作用會發(fā)生在近30%的患者中,但大多數(shù)人并不會表現(xiàn)出癥狀,,僅能在腦成像中觀察到這種情況,。
目前該試驗結果還需要復制,來自加利福尼亞大學的科學家Michael Weiner博士表示,,即便如此,,阿爾茲海默病新型藥物donanemab的開發(fā)對于很多患者和家庭而言都是一大喜訊。(生物谷Bioon.com)

Experimental drug for Alzheimer's disease shows promise
Drug maker Eli Lilly on Monday announced promising results from a small study of an experimental Alzheimer's disease drug called donanemab.
The two-year, phase 2 clinical trial included 272 patients with mild-to-moderate Alzheimer's disease symptoms. The company said that patients who received the drug by infusion every four weeks had a 32 percent slower rate of mental decline than those who were given a placebo, The New York Times reported.
