新試驗發現首個減緩阿爾茨海默病對患者大腦損傷的藥物，這個名為 “ lecanemab ” 的藥物 “意義重大”。這項試驗的結果為此領域幾十年的高失敗率畫上句號，并表明用藥物治療阿爾茨海默病（最常見的失智癥）的新時代并非遙不可及。

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.

首個能減緩阿爾茨海默病病程的藥物的試驗結果被稱為是 “有歷史意義的”，這個消息轟動了業界的研究人員和慈善機構。該藥物的制造商表示將于明年1月向監管機構提交申請，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。在實驗室生產該抗體的成本很高，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，很少有患者有證實性診斷測試結果，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監測服藥對患者身體產生的副作用。
