抗CD47 / PD-L1双特异性抗体临床试验:中国首例患者已入组

2020-08-03 Allan MedSci原创

重组抗CD47 / PD-L1双特异性抗体(IBI322)的I期临床试验(CIBI322A101)已正式开始,中国首例患者已入组。

尽管免疫检查点抑制剂在治疗多​​种肿瘤方面显示出令人鼓舞的结果,但部分患者已发展出耐药性,免疫检查点抑制剂的疗效有待进一步提高,因此,开发下一代抗肿瘤免疫双特异性抗体具有重要价值,CD47则是癌症免疫治疗中最有希望的靶标之一。

生物制药公司信达(Innovent)今日宣布,重组抗CD47 / PD-L1双特异性抗体(IBI322)的I期临床试验(CIBI322A101)已正式开始,中国首例患者已入组。CIBI322A101是一项在中国进行的Ia/Ib期临床研究,该研究的主要目的是评估IBI322在标准治疗失败的晚期恶性肿瘤患者中的安全性、耐受性和抗肿瘤疗效。

IBI322是一种重组抗CD47 / PD-L1双特异性抗体,可阻断PD-1 / PD-L1和CD47 /SIRP-α途径。临床前研究表明,IBI322可有效阻断CD47-SIRP-α相互作用并诱导巨噬细胞吞噬CD47阳性肿瘤细胞。另一方面,IBI322有效阻断PD-1与PD-L1的结合并激活CD4阳性的T淋巴细胞。
