智通财经APP获悉,宜明昂科-B(01541)盘中涨超6%,截至发稿,涨6.26%,报5.77港元,成交额1697.78万港元。

消息面上,3月6日,宜明昂科-B发布公告,集团已获中华人民共和国国家药品监督管理局(国家药监局)批准进行IMM01(替达派西普)联合IMM2510(珀维拉芙普α),另加化疗或不加化疗用于治疗晚期恶性肿瘤的临床试验。这一重大进展标志着公司在快速推进IMM01(替达派西普)及IMM2510(珀维拉芙普α)的临床研究方面又迈出了关键一步。

集团的核心产品IMM01(替达派西普)是创新靶向CD47的分子。该款产品是中国首个进入临床阶段的SIRPα-Fc融合蛋白。具有免疫球蛋白G1(IgG1)Fc的IMM01(替达派西普)能够通过双重作用机制充分激活巨噬细胞—同时通过干扰CD47/SIRPα相互作用阻断“别吃我”信号,并通过激活巨噬细胞的Fc-gamma(Fcγ)受体传递“吃我”信号。

此外,IMM01(替达派西普)的CD47结合结构域经过特别改造能够避免与人体红细胞(RBC)结合。凭借差异化的分子设计,IMM01(替达派西普)表现出良好的安全性并证实其激活巨噬细胞的能力。IMM01(替达派西普)联合阿扎胞苷进行CMML一线治疗于2023年11月获美国食品药品监督管理局(FDA)授予的孤儿药资格认定。
