Regeneron新藥試驗失利 股價急挫13%




Regeneron股價開盤前急挫近13% 因其治療「吸煙者肺病」的實驗藥物在關鍵臨床試驗中失利

美國生物製藥公司Regeneron與其合作夥伴Sanofi共同研發的實驗藥物itepekimab,原本被寄望成為治療慢性阻塞性肺病(COPD,俗稱「吸煙者肺」)的一大突破。然而,該藥物在最新的晚期臨床試驗中表現不佳,導致Regeneron股價在周五美股開盤前下跌近13%。儘管如此,該藥物在另一項試驗中卻取得成功,令情況略顯複雜。

Regeneron和Sanofi針對曾經吸煙的成年COPD患者進行了兩項主要試驗,這種疾病治療選擇有限。市場原本預期itepekimab有望覆蓋比兩家公司熱銷藥物Dupixent更廣泛的患者群,而Dupixent目前也獲批用於COPD治療。Barclays分析師Emily Field指出,基於數據結果,Dupixent仍可能是醫生的首選藥物。

值得一提的是,葛蘭素史克(GSK)旗下剛獲批用於COPD的Nucala同樣是暢銷藥。根據美國政府資料,約有1,600萬美國成年人患有COPD。

Regeneron今年以來股價已經下跌約15%,此次消息公布後,該股在盤前交易價格約為530美元,總市值約653.6億美元。

在一項涵蓋1,127名患者的52週試驗中,itepekimab相較安慰劑,顯著降低了患者COPD急性惡化(病情突然加重)的發生率,減少幅度達27%。然而,在另一項涉及較少前吸煙者的試驗中,該藥物未能達到主要終點,儘管早期數據曾顯示一定療效。

這款藥物由Regeneron和Sanofi共同開發,主要通過結合並抑制白介素-33(IL-33)蛋白,來減少COPD引發的炎症反應。

COPD是一種常見的肺部疾病,導致氣流受限和呼吸困難,主要影響吸煙者,但污染物亦可成為病因之一。

兩家公司表示,將會繼續評估試驗數據,並與監管機構討論下一步策略。

從估值角度來看,Regeneron的市盈率為16.15,較同業Gilead的13.62及Bristol Myers Squibb的7.29為高。

評論與啟示:

這次Regeneron的臨床試驗結果呈現「一喜一憂」的情況,反映出新藥研發的不確定性及挑戰。雖然在一項試驗中取得了顯著療效,但另一項試驗的失敗足以令市場信心受挫,股價因此大幅波動。這提醒我們,單一藥物的臨床試驗結果需多角度審視,尤其是涉及複雜疾病如COPD,患者異質性和試驗設計差異都可能影響結果。

此外,市場對於現有治療方案如Dupixent和Nucala的依賴,顯示新藥若無法展現明顯優勢,獲得醫生及患者的青睞將非常困難。Regeneron和Sanofi接下來如何調整策略、優化試驗設計,或尋求其他適應症,將是關鍵。

對香港及全球投資者而言,這也彰顯生物科技股的高風險高回報特性。投資此類股票需要密切關注臨床數據更新及監管動態,避免過度追高。從更廣義的角度看,COPD作為全球重要的公共衛生問題,市場對於有效治療方案的需求依然龐大,研發投入仍具長遠價值。

最後,這件事亦提醒我們在閱讀和報道醫藥新聞時,應該深入分析數據背後的複雜性,而非單純聚焦股價波動,從而提供更全面、具洞察力的報導,幫助讀者作出更明智的判斷。
