金吾财讯 | 英国药企葛兰素史克(GSK)股价承压,报51.56美元,跌2.29%。

消息面上,公司披露临床数据,核心在研止咳药物 camlipixant 两项三期关键试验未达成一致疗效终点,公司决定终止该药物针对难治性慢性咳嗽适应症的全部研发工作,受利空冲击个股伦敦市场股价走弱。

该药物为高选择性 P2X3 受体拮抗剂,是 2023 年 GSK 斥 20 亿美元全额现金收购 Bellus Health 的核心资产,原本被市场寄予厚望,用于填补难治性慢性咳嗽临床空白。两项注册三期 CALM-1、CALM-2 试验数据分化明显:50mg 每日两次剂量仅在 CALM-1 第 12 周达成主要终点,相较安慰剂显著降低 24 小时咳嗽频次;但 CALM-2 第 24 周随访未复刻有效结果,25mg 低剂量方案在两项试验中均无统计学疗效差异,全部次要疗效指标同样未达标,综合数据判定药物难以给患者治疗方案带来实质性改善。管线规划出现拆分调整,难治性慢性咳嗽研发全线叫停,但针对成人肠易激综合征的 2b 期 BALANCE 临床试验维持推进,保留药物在消化领域的研发价值。

本次 20 亿并购的核心呼吸管线宣告失败,大幅削弱公司呼吸板块中长期增长预期,市场担忧并购投入回报不及预期;肠易激综合征赛道市场空间相对有限,难以完全对冲止咳适应症临床失利带来的估值压力。
