武田制药AI开发的银屑病药片试验成功

武田制药宣布,其AI辅助的口服银屑病药物zasocitinib在晚期试验中证明安全有效。这种每日一次的药片在清除中重度斑块状银屑病患者皮肤方面,优于安慰剂和现有疗法apremilast。如果获批,它将成为首批利用人工智能发现的药物之一。

武田制药于12月18日宣布,其实验性口服药物zasocitinib(又称TAK-279)在中重度斑块状银屑病的晚期临床试验中显示出安全性和有效性。公司声明称,服用这种每日一次药片的患者,其皮肤清澈度显著优于服用安慰剂或现有治疗apremilast的患者。武田计划从2026财年开始向美国食品药品监督管理局及其他监管机构提交数据。

该药物的发现高度依赖人工智能,算法加速了从大量分子中筛选出zasocitinib的过程。起源于该药物的Nimbus Therapeutics首席执行官Jeb Keiper表示,这些算法“显著加速了识别过程”。2023年,武田以40亿美元预付款从波士顿的Nimbus Therapeutics收购zasocitinib,并可能额外获得20亿美元的里程碑付款。

该疗法是武田制药缓解其重磅产品Entyvio面临仿制药竞争导致收入损失的更广泛计划的一部分。Jefferies Japan分析师Stephen Barker估计,如果扩展到炎症性肠病等适应症,zasocitinib峰值销售额可能达到50亿美元。根据Fortune Business Insights的数据,2024年全球银屑病市场价值270亿美元,预计到2032年将几乎翻倍至580亿美元。银屑病是一种慢性自身免疫性疾病,影响全球超过1.25亿人,会引起瘙痒、鳞屑性皮疹。
