啟愈生物今日宣布,公司將在當地時(shí)間2023年1月19-21日于舊金山會(huì )場(chǎng)及線(xiàn)上舉行的美國臨床腫瘤學(xué)會(huì )胃腸道腫瘤研討會(huì )(ASCO Gastrointestinal Cancers Symposium)上展示其Q-1802項目的臨床Ⅰ期數據。該研究結果摘要將刊登于A(yíng)SCO GI年會(huì )摘要匯集(#382),摘要概覽如下:
Interim results of a first-in-human phase 1 study of Q-1802, a CLDN18.2/PD-L1 bsABs in patients with relapsed or refractory solid tumors
Authors: Yakun Wang1, Jifang Gong1, Yuping Sun2, Jian Zhang3, Yanqiao Zhang4 ,Shuqin ni2, Jie Hou5, Xiaohua Chen5, Yusheng Wang6, Qin Yu7, Xiangdong Qu8, Yejie Du8, Li Wei8, Tao Yu8, Lin Shen1
● Q-1802 is a humanized bispecific antibody
● targets both the tumor -specific antigen CLDN18.2 and the immune checkpoint PD-L1
● Q-1802 has excellent safety, tolerability
● Q-1802 has excellent anti-tumor activity in CLDN18.2 positive GI patients
關(guān)于Q-1802
Q-1802是由啟愈生物自主開(kāi)發(fā)的,可以同時(shí)靶向CLDN18.2及PD-L1的人源化雙特異性抗體。Q-1802為FDA首 個(gè)批準并最 先進(jìn)入臨床、以及首 個(gè)于A(yíng)SCO年會(huì )上公布臨床數據的CLDN18.2/PD-L1雙抗。在機制上,Q-1802采用多種免疫機制來(lái)殺傷腫瘤細胞,為治療CLDN18.2表達的晚期實(shí)體瘤提供了全新策略。Q-1802具有高親和力和選擇性,CLDN18.2低表達至高表達患者群體均可獲益,目前的臨床I期數據驗證了其出色的安全性及有效性。Q-1802分子構建簡(jiǎn)單有效,工藝流程穩健高產(chǎn),成本接近單抗。
