阿斯利康(AstraZeneca)因设计缺陷导致Wainua心脏试验失败,股价下跌9%

阿斯利康(AstraZeneca)因设计缺陷导致Wainua心脏试验失败,股价下跌9%

YWO NEWS | EQUITIES | DEEP DIVE / ANALYSIS

周四,阿斯利康(AstraZeneca)在伦敦上市的股票下跌 9.1% ,为自2020年3月以来单日跌幅最大的一次。此前,这家英国制药商宣布其用于治疗心脏病的Wainua后期试验未能达到主要终点, CNBC的Elsa Ohlen 报道称。在纽约证交所上市的 AZN 股票在盘前交易中下跌 8.4%

该药物Wainua正在治疗转甲状腺素蛋白淀粉样变性心肌病(ATTR-CM)患者,这是一种罕见且危及生命的疾病,其中错误折叠的蛋白质积聚在心肌中,导致心肌僵硬并最终导致心力衰竭。阿斯利康(AstraZeneca)周四上午在一份新闻稿中确认,在超过140周的时间里,在标准治疗基础上加用Wainua并未显示出与安慰剂相比,在死亡和复发性心脏事件方面有统计学上的显著降低。 阿斯利康(AstraZeneca)周四上午在一份新闻稿中确认。全球约有五十万人患有此病。


试验结果和患者群体考量 

根据阿斯利康(AstraZeneca)和CNBC引用的分析师的说法,在评估试验结果时,注意力集中在研究设计的方面。在该研究队列中, 57% 的患者在基线时已接受稳定剂治疗——一种可以阻止蛋白质首先发生错误折叠的药物。另有 24% 的患者在试验期间开始使用稳定剂。根据已公布的试验结果,在标准治疗基础上加用Wainua并未显示出在主要终点方面有统计学上的显著改善。

对于基线时未服用稳定剂的患者,Wainua与安慰剂相比,在死亡和心脏事件方面确实显示出“名义上显著”的风险降低。 AstraZeneca表示. 尽管亚组研究结果并未改变主要终点,但AstraZeneca将其作为整体研究结果的一部分进行了报告。

CNBC援引的杰富瑞分析师表示:

“AstraZeneca本应具备‘极其出色的试验设计能力’,而看到试验因稳定剂患者比例等设计缺陷而失败,将损害公司的信誉。”

杰富瑞在讨论试验结果时,将研究设计的重要性归因于此。在担任CEO的14年多时间里,AstraZeneca的声誉部分建立在其能够进行严谨试验的基础上,尤其是在肿瘤学领域。一项归因于患者队列设计缺陷的失败,为批评者提供了一个结构性论点,而不仅仅是统计学上的论点。


800亿美元目标——试验结果后的分析师观点 

杰富瑞并未因此危及AstraZeneca 2030年800亿美元的销售目标,但根据 减少25亿美元 的风险调整后销售额来预测Wainua的销售情况, CNBC报道称。分析师指出,AstraZeneca“对主要终点和组合用药能力非常有信心”——这使得此次失利比管理层已预警不确定性的试验更难接受。

“更大的问题可能是管理层对试验能够达到主要终点以及在背景疗法之上显示疗效的能力非常有信心,这在一定程度上会削弱其信誉,”杰富瑞表示。

CNBC援引的摩根大通表示,其在商业化道路上走得更远:它表示,鉴于主要终点未达标,AstraZeneca不太可能为Wainua申请额外的ATTR-CM适应症批准,并指出Alnylam Pharmaceuticals已获批的同类适应症治疗药物是竞争壁垒。

AstraZeneca确认Wainua的现有许可证不受影响。该药物已获批用于治疗由错误折叠蛋白引起神经损伤而非心脏损伤的疾病,并在欧洲以Wainzua品牌销售。周四的失败特指心脏适应症的扩展,而非基础批准。


联合开发商Ionis和竞争对手Alnylam走势分化

连带损害直接波及Ionis Pharmaceuticals,该公司在美国与阿斯利康联合开发Wainua。 IONS 股价周四盘前下跌 20%CNBC报道称 ——跌幅约为阿斯利康自身跌幅的两倍,反映出该药物对Ionis公司管线的重要性比例更大。

相比之下,  Alnylam Pharmaceuticals 股价上涨 17% ,在同一消息公布后盘前交易中上涨。Alnylam已有一种治疗ATTR-CM的药物上市,Wainua的失败消除了其在上市前可能对其市场地位构成挑战的竞争疗法。这种三方分化——AZN下跌9%,IONS下跌20%,ALNY上涨17%——反映了公告发布后市场反应的不同。 


此后将如何发展

Jefferies指出,该股可能要到阿斯利康的下一个主要催化剂—— AVANZAR癌症试验 ——公布结果后才能恢复稳定, CNBC报道称.分析师表示,他们“不排除人们会暂时观望,直到催化剂路径更清晰为止。”这种表述将当前的动荡定位为一种观望状态,而非必然的结构性重新评级——尽管Jefferies提出的信誉问题可能需要一次以上清晰的读数才能完全解决。

在周四公布消息后,阿斯利康尚未公布Wainua心脏适应症的修订时间表或申报计划。该公司的新闻稿仅确认现有许可证保持不变,并相信这些结果“支持更大的科学”理解——这句话在可获取的源文本中被截断了。 CNBC 周四上午公布了完整声明。

Jefferies指出,尽管降低了对Wainua的风险调整后销售预期,但仍继续将其纳入阿斯利康更长期的收入目标模型。分析师们还强调,在试验结果公布后,市场参与者可能会继续关注管理层的信誉。
