康方生物-B(09926.HK):AK104、AK112、AK117和AK105最新研究進展將在ASCO 2021上發佈
格隆匯 05-20 08:00

格隆匯5月20日丨康方生物-B(09926.HK)公吿,將於2021年美國臨牀腫瘤學會年會(ASCO2021)上發佈Cadonilimab(PD-1/CTLA-4雙特異性抗體,研發代號:AK104)、PD-1/VEGF雙特異性抗體(研發代號:AK112)、CD47單抗(研發代號:AK117)、派安普利(PD-1單抗,研發代號:AK105)的相關臨牀研究最新進展。摘要及電子海報呈列材料將在ASCO2021之後,於公司網站上發佈:http://www.akesobio.com。

Cadonilimab (AK104)是公司自主研發的新型的、潛在下一代首創PD-1/CTLA-4雙特異性腫瘤免疫治療骨幹藥物,主要適應症包括肝癌、宮頸癌、肺癌、胃癌、食管鱗癌及鼻咽癌等。在宮頸癌、胃癌等多種腫瘤的研究階段性初步資料顯示,Cadonilimab比PD-1聯合CTLA-4的聯合療法相比,毒性顯着降低,具有明顯的安全性和療效優勢。AK104專案是2017年國家衞健委及科技部十三五重大新藥創制科技重大專項支持專案,2017年廣東省珠江人才計劃引進創新創業團隊支持專案。被中國醫藥生物技術協會和《中國醫藥生物技術》雜誌共同評為2017年中國醫藥生物技術十大進展之一。

AK112是公司自主研發,全球行業內首個進入臨牀研究的PD-1/VEGF雙特異性抗體。AK112是基於公司獨特的TETRABODY技術設計,可阻斷PD-1與PD-L1和PD-L2的結合,並同時阻斷VEGF與VEGF受體的結合。PD-1抗體與VEGF阻斷劑的聯合療法已在多種瘤種(如腎細胞癌、非小細胞肺癌和肝細胞癌)中顯示出強大的療效。鑑於VEGF和PD-1在腫瘤微環境中的共表達,與聯合療法相比,AK112作為單一藥物同時阻斷這兩個靶點,可能會更有效地阻斷這兩個通路,從而增強抗腫瘤活性。

派安普利(PD-1單抗,AK105)由公司與中國生物製藥有限公司旗下正大天晴藥業集團股份有限公司所設立的合營企業共同開發及商業化。派安普利的結晶(Fc)受體和補體介導效用功能通過Fc區突變而完全去除,同時與國外已上市PD-1抗體相比抗原結合解離速率較慢。這些特點使得派安普利具有更有效地阻斷PD-1通路的活性,並維持更強的T細胞抗腫瘤活性,有可能成為臨牀獲益更好的抗PD-1藥物。中國國家藥品監督管理局(NMPA)已於2020年5月受理派安普利單抗用於治療至少經過二線系統化療復發或難治性經典型霍奇金淋巴瘤(r/rcHL)的新藥上市申請。派安普利三線治療轉移性鼻咽癌註冊性臨牀試驗亦達到主要終點。

此外,AK117是公司自主研發的新一代人源化IgG4 mAb,AK117可與腫瘤細胞上表達的CD47結合,阻斷CD47與其受體SIRPα(在吞噬細胞上表達)的相互作用,增強吞噬細胞對腫瘤細胞的吞噬活性,從而抑制腫瘤生長。臨牀前研究也顯示,AK117在保留抗腫瘤活性的同時,消除了紅細胞凝集作用,並顯着降低其介導的巨噬細胞對紅細胞吞噬活性,區別於其他抗CD47抗體藥物,AK117具有不引起紅細胞聚集的差異化特徵。並且AK117介導巨噬細胞對紅細胞吞噬的活性顯著弱於對腫瘤細胞的吞噬。同時,相較於其他CD47抗體所表現出的明顯貧血症狀,AK117在食蟹猴中僅出現輕微的紅細胞變化,並且未觀察到對血小板的毒性作用。
