本期看點
1.天境生物(I-Mab)公布了其雙特異性抗體givastomig聯合nivolumab和mFOLFOX6,一線治療Claudin 18.2陽性晚期轉移性胃癌患者的1b期試驗的積極數據,在所有劑量組中確認的客觀緩解率(ORR)為71%,疾病控制率(DCR)達100%。
2.多靶點抑制劑gedatolisib聯合雄激素受體抑制劑治療轉移性去勢抵抗性前列腺癌(mCRPC)的早期臨床結果積極,6個月的放射學無進展生存率(rPFS)達66%。
Givastomig:公布1b期聯合治療試驗數據
天境生物公布了其雙特異性抗體givastomig的1b期聯合治療試驗的積極數據。Givastomig是一種靶向Claudin 18.2(CLDN18.2)陽性腫瘤細胞的雙特異性抗體,在表達Claudin 18.2的腫瘤微環境中通過4-1BB信號通路有條件地激活T細胞。該藥由天境生物牽頭與ABL Bio公司共同開發,兩方平等共享除大中華區和韓國以外的全球權益。目前,givastomig正被開發用于一線治療轉移性胃癌,并具有在其他實體瘤中進一步拓展的潛力。
截至2025年5月15日的數據,17例Claudin 18.2陽性晚期轉移性胃癌患者接受了不同劑量的givastomig聯合nivolumab和mFOLFOX6作為一線治療。數據顯示,在所有劑量組中確認的ORR為71%(12/17),DCR達100%。在選定用于劑量擴展的兩個劑量組(8 mg/kg和12 mg/kg)中,ORR為83%(10/12)。值得注意的是,即使在PD-L1或CLDN18.2表達水平較低的患者中也觀察到了緩解。17名患者中有8名仍在接受治療,截至數據截止日期,最長的治療持續時間為13.3個月。安全性方面,聯合療法的耐受性良好,未出現3級或以上的惡心嘔吐事件,僅有一例3級治療相關不良事件(肝酶升高)。
Gedatolisib:公布1期聯合治療試驗數據
Celcuity公司公布了其在研藥物gedatolisib在一項針對轉移性去勢抵抗性前列腺癌患者的1期臨床試驗中的初步積極數據。Gedatolisib是一種強效的多靶點抑制劑,可同時靶向所有四種I類PI3K亞型以及mTOR復合物mTORC1和mTORC2,從而全面阻斷關鍵的PI3K/AKT/mTOR(PAM)信號通路。
該試驗評估了gedatolisib聯合雄激素受體抑制劑darolutamide在mCRPC患者中的安全性和初步療效。截至2025年5月30日的數據,6個月的rPFS為66%。安全性方面,沒有患者因治療相關不良事件停止治療,也未發生劑量調整,沒有3級高血糖事件,僅10.5%的患者出現2-3級口腔炎,均為可控范圍。在另一項gedatolisib聯合曲妥珠單抗作為3線療法治療HER2陽性轉移性乳腺癌患者的2期臨床試驗中,ORR為43%。
ART26.12:公布首個人體試驗數據
Artelo Biosciences公司公布了其在研藥物ART26.12的首個人體臨床試驗的積極結果。ART26.12是一種新型脂肪酸結合蛋白5(FABP5)抑制劑。作為一種外周作用的非阿片類、非甾體類鎮痛劑,其初步臨床開發目標是用于治療化療引起的周圍神經病變(CIPN)。新聞稿指出,ART26.12是首個在人體中進行評估的口服活性FABP5抑制劑。此次公布的數據顯示,ART26.12在健康受試者中表現出良好的安全性和可預測的藥代動力學特性,與其此前在臨床前研究中觀察到的表現一致。
Aritinercept(AUR200):公布1期臨床試驗數據
Aurinia Pharmaceuticals公司公布了其用于治療自身免疫疾病的B細胞活化因子(BAFF)和增殖誘導配體(APRIL)雙重抑制劑aritinercept的1期單劑量遞增(SAD)研究的積極結果。Aritinercept在所有測試的劑量水平下都具有良好的耐受性。單劑量aritinercept可使受試者的免疫球蛋白穩定且持久地減少,從基線到接受治療后第28天,免疫球蛋白A(IgA)、免疫球蛋白M(IgM)和免疫球蛋白G(IgG)的平均降幅分別為48%、55%和20%。藥效學效應支持每月一次的給藥方案。
