6月16日早間,三葉草生物發(fā)布公告稱將與國光生物科技股份有限公司(以下簡稱:國光生物)終止合作。

6月15日,三葉草生物已經(jīng)向國光生物發(fā)出通知以終止獨家協(xié)議,自2025年6月30日生效。該終止生效后,三葉草生物將不再于中國大陸分銷四價季節(jié)性流感疫苗。

6月16日港股開盤,三葉草生物跌4.62%,市值僅剩3.31億港元。當日,界面新聞記者詢問三葉草生物關(guān)于終止合作的具體原因,對方稱一切以公告為準。

三葉草生物與國光生物的合作可追溯至2023年2月,當時雙方簽訂了關(guān)于AdimFlu-S(QIS)疫苗在中國大陸分銷的獨家協(xié)議。

據(jù)三葉草生物公告,AdimFlu-S(QIS)是截至2023年雙方合作時,國內(nèi)唯一獲批用于三歲及以上人群的進口四價季節(jié)性流感疫苗,于2022年1月獲得中國國家藥品監(jiān)督管理局批準。該獨家協(xié)議還授權(quán)三葉草生物獲得注冊部門批準后,在孟加拉國、巴西和菲律賓商業(yè)化AdimFlu-S(QIS),并有望與國光生物合作開發(fā)其他候選疫苗,包括下一代流感疫苗。

當時,三葉草生物認為,在中國大陸不斷增長且穩(wěn)定的流感疫苗市場中,這筆交易預(yù)計將在2023年對三葉草生物的財務(wù)狀況帶來增量,并在2024年及以后創(chuàng)造具有意義的增長。

在2023年年報中,三葉草生物稱,當年該流感疫苗在28個省份獲得準入,并在9月獲得批簽發(fā)并開始銷售。2023年,三葉草生物實現(xiàn)營收3925.5萬元,主要源自SCB-2019(CpG1018╱鋁佐劑)及四價季節(jié)性流感疫苗在中國商業(yè)上市。

2023年多家流感疫苗廠商業(yè)績實現(xiàn)增長,這和當年的流感病毒卷土重來,市場需求恢復(fù)有關(guān)。比如,主要產(chǎn)品為四價流感疫苗的頭部疫苗廠商華蘭疫苗在2023年的歸母凈利潤同比增長65.49%。

不過到了2024年,流感疫苗需求大幅削減。當年華蘭疫苗實現(xiàn)營收11.28億元,同比下降53.21%;實現(xiàn)凈利潤2.06億元,同比下降76.10%。而三葉草生物2024年實現(xiàn)收入3840萬元,與去年同期相當,因銷量上升帶來的四價流感疫苗AdimFlu-S收入的增加,被確認的AdimFlu-S銷售退回人民幣1160萬元所抵銷。

此外,國光生物的疫苗還曾出現(xiàn)質(zhì)量問題。去年10月,我國臺灣省發(fā)現(xiàn)一劑國光生物的流感疫苗變色。國光生物當時解釋稱,是該產(chǎn)品在膠塞泡到流感疫苗液體后,膠塞內(nèi)硫化合物溶出,致使疫苗變色。三葉草生物作為國光生物四價流感疫苗在大陸的代理商也受到關(guān)注。

另外,四價流感疫苗中包含的B/Yamagata譜系毒株已不是主流毒株,長期來看銷量可能還會下滑。一位西南地區(qū)某市的疾控人士對界面新聞記者表示,四價流感疫苗中包含的乙型流感病毒B/Yamagata譜系毒株已經(jīng)很久沒有出現(xiàn),目前已經(jīng)沒有接種四價流感疫苗的必要。

實際上,2024年2月,世界衛(wèi)生組織發(fā)表的《2024-2025年北半球流感季節(jié)使用的流感病毒疫苗推薦成分》文章就表示,建議在2024-2025年北半球流感季節(jié)使用三價疫苗,而B/Yamagata譜系疫苗成分因不再需要而應(yīng)被排除在外。

2021年9月,國際頂刊《自然》子刊發(fā)表的一篇名為《COVID-19大流行期間流感譜系滅絕?》的文章也稱,從2020年4月到2021年8月,全球范圍內(nèi)沒有再分離出乙型流感病毒B/Yamagata譜系毒株,這表明該流感譜系可能已經(jīng)滅絕。

目前,三葉草生物已經(jīng)商業(yè)化的兩款產(chǎn)品分別是重組蛋白新冠疫苗SCB-2019(CpG1018/鋁佐劑)和進口四價季節(jié)性流感疫苗AdimFlu-S。

其中,SCB-2019于2023年2月在國內(nèi)正式上市,但沒過多久新冠疫苗整體陷入滯銷困境,三葉草生物也因需求下滑,對相關(guān)庫存進行了減值處理。并且,今年3月,三葉草生物還被全球疫苗免疫聯(lián)盟要求退還2.24億美元的新冠疫苗采購預(yù)付款。三葉草生物則認為該要求缺乏依據(jù),拒絕退款。

因此,三葉草生物最主要的商業(yè)化產(chǎn)品是與國光生物合作引進的AdimFlu-S。與國光生物合作終止后,三葉草生物的商業(yè)化產(chǎn)品便只剩SCB-2019(CpG1018/鋁佐劑)一款產(chǎn)品,但是這款產(chǎn)品如今也無法為三葉草生物帶來穩(wěn)定的現(xiàn)金流。

三葉草生物目前的希望寄托在二價呼吸道合胞病毒(RSV)疫苗SCB-1019上。今年3月24日,該候選疫苗獲得美國食藥監(jiān)局批準,用于評估該候選疫苗重復(fù)接種的Ⅰ期臨床試驗已完成首批受試者入組。不過,三葉草生物如今的現(xiàn)金流狀況較差,截至2024年12月31日,三葉草生物的現(xiàn)金及銀行結(jié)余由2023年年底的10.95億元減少至為5.56億元。
