智通財經APP訊,創勝集團-B(06628)發佈公告,公司已獲得中國國家藥品監督管理局藥品審評中心(CDE)和韓國食品藥品安全部(MFDS)批准,在HER2陰性、CLDN18.2表達的一線局部晚期或轉移性胃或胃食管連接部(G/GEJ)腺癌患者中,開展Osemitamab(TST001)聯合納武利尤單抗與化療的TranStar 301全球III期關鍵性臨牀試驗。此外,集團正在與歐盟和FDA進行監管互動。

胃癌(GC)是全球癌症死亡的第四大原因,約佔所有癌症相關死亡率的7.7%。胃癌的五年生存率仍在30%左右。抗PD-1抗體納武利尤單抗已於全球獲批用於晚期或轉移性HER2陰性胃╱胃食管連接部腺癌患者的一線治療。

Osemitamab(TST001)是一種第二代靶向CLDN18.2的人源化抗體,具有增強的ADCC作用。其在具有廣泛CLDN18.2表達的臨牀前模型中顯示出抗腫瘤活性。近日,公司於2023年ASCO年會和2023年ESMO GI年會公佈Osemitamab(TST001)聯合CAPOX作爲胃╱胃食管連接部腺癌一線治療的療效數據。64例CLDN18.2陽性患者(定義爲:用LDT方法≥10%腫瘤細胞的Claudin18.2 IHC膜染色強度≥1+,篩選出約55%的患者)接受了治療,其中49例接受了6mg/kg的劑量治療。數據顯示,所有劑量組中,預計中位無進展生存期爲9.5個月,與所有CLDN18.2表達水平一致,預計中位緩解持續時間爲9.9個月。

臨牀前研究已證明Osemitamab(TST001)和抗PD-1抗體在CLDN18.2表達的腫瘤模型中具有協同的抗腫瘤活性。近期,公司報告稱,已有82名患者入組TranStar 102,以評估Osemitamab(TST001)聯合納武利尤單抗與CAPOX治療的安全性及療效。迄今爲止,該聯合療法的耐受性良好。

TranStar 301是一項全球範圍內進行的隨機、雙盲、安慰劑對照的III期臨牀試驗,旨在評估Osemitamab(TST001)聯合納武利尤單抗與化療在HER2陰性、CLDN18.2表達的局部晚期或轉移性胃╱胃食管連接部腺癌患者中的一線治療效果。

公司全球藥物開發執行副總裁、首席醫學官Caroline Germa博士表示:“集團正在積極推進Osemitamab(TST001)聯合納武利尤單抗與化療治療一線CLDN18.2表達胃╱胃食管連接部腺癌的大型跨國III期臨牀試驗。獲得CDE和MFDS批准是一個令人興奮的里程碑,相信其他里程碑也即將到來。我們期待在未來能夠與大家分享更多臨牀進展。”
