新試驗(yàn)發(fā)現(xiàn)首個(gè)減緩阿爾茨海默病對(duì)患者大腦損傷的藥物，這個(gè)名為 “ lecanemab ” 的藥物 “意義重大”。這項(xiàng)試驗(yàn)的結(jié)果為此領(lǐng)域幾十年的高失敗率畫上句號(hào)，并表明用藥物治療阿爾茨海默?。ㄗ畛Ｒ姷氖е前Y）的新時(shí)代并非遙不可及。

News of the first drug that can slow the progression of Alzheimer's has been called historic and prompted huge excitement among researchers and charities. The manufacturer said it would be filing for regulatory approval in January and hope lecanemab may be available from September in the UK.

首個(gè)能減緩阿爾茨海默病病程的藥物的試驗(yàn)結(jié)果被稱為是 “有歷史意義的”，這個(gè)消息轟動(dòng)了業(yè)界的研究人員和慈善機(jī)構(gòu)。該藥物的制造商表示將于明年1月向監(jiān)管機(jī)構(gòu)提交申請(qǐng)，并希望 lecanemab 能從明年9月起在英國上市。

Lecanemab is a monoclonal antibody. These are costly to produce in the lab, so will inevitably be an expensive product. It is only suitable for those with early-stage Alzheimer's, but few patients in the UK have the confirmatory diagnostic test needed to show they could benefit from the drug. So, its use could be very limited at first, and patients will have to be carefully monitored for side effects.

Lecanemab 是一種單克隆抗體。在實(shí)驗(yàn)室生產(chǎn)該抗體的成本很高，因此它必將是一種昂貴的藥品。該藥只適用于治療早期阿爾茨海默病的患者，但在英國，很少有患者有證實(shí)性診斷測試結(jié)果，表明他們能從這種藥物中獲益。因此，起初該藥物的使用可能非常有限，而且研究人員必須仔細(xì)監(jiān)測服藥對(duì)患者身體產(chǎn)生的副作用。
