                                                                                                                                                                          2019-02-07 20:50 绍兴新闻门户

                                                                                                                                                                            信达生物-B(01801)发布公告,集团针对死亡受体蛋白1(PD-1)及肿瘤相关抗原(TAA)的一个未披露靶点的重组全人源抗程序性双特异性抗体IBI318的新药临床试验(IND)申请,近日已获中国国家药品监督管理局批准,拟在患者体内开展针对血液肿瘤及晚期实体瘤的临床试验。

                                                                                                                                                                            PD-1为抗肿瘤免疫治疗领域中已确证的靶点。PD-1单克隆抗体单药及联合化疗在多个肿瘤领域中均表现出比之前标准治疗优异的疗效,为患者提供全新的治疗方案。然而,目前采用PD-1单克隆抗体单药及联合治疗实体瘤,只对部分癌症患者有效。开发更为有效的免疫疗法有望使更多癌症患者从此项创新疗法中获益。

                                                                                                                                                                            IBI-318是针对PD-1及TAA的一个未披露靶点的重组全人源免疫球蛋白G1(IgG1)双特异性抗体,有望为满足患者医疗需求提供创新解决方案。IBI-318获得NMPA颁发的新药临床试验批件,标志着集团在肿瘤免疫治疗领域的创新研发方面取得重大进展。

                                                                                                                                                                            据悉,IBI-318是由礼来公司与集团共同发现,并由集团负责在中国进行开发。IBI318为针对PD-1及TAA的一个未披露靶点的重组全人源IgG1双特异性抗体。IBI318同时阻断PD-1及另一个肿瘤相关信号转导途径,并增强免疫突触的形成,从而可能地加强抗肿瘤活性及增加抗肿瘤疗效。
