康方生物-B(09926)公布,该公司核心自主研发的、全球首创的新型肿瘤免疫治疗双特异性抗体新药Cadonilimab(PD-1/CTLA-4双特异性抗体,研发代号:AK104)获得美国食品药品监督管理局(“FDA”)授予的孤儿药资格认定,用于治疗宫颈癌(除极早期IA1期之外)。这是继2020年,Cadonilimab治疗经标准治疗后的复发或转移性宫颈癌获得FDA授予快速审批通道资格(FTD)和中华人民共和国国家药品监督管理局(NMPA)授予“突破性治疗药物品种”后的又一重要进展。
公告称,含铂药物化疗治疗失败的宫颈癌患者,目前尚无获批的标准治疗。后线化疗治疗的客观缓解率(ORR)不足10%,无进展生存时间短,长期化疗耐受性差,不良反应发生率较高,极需要有效的治疗药物来提高患者的疗效获益。目前,Cadonilimab在中国用于经标准治疗后复发或转移性宫颈癌的注册性II期临床试验已经完成患者入组。
Cadonilimab(AK104)是该公司自主研发的新型的、潜在下一代首创PD-1/CTLA-4双特异性肿瘤免疫治疗骨干药物,主要适应症包括肝癌、宫颈癌、肺癌、胃癌、食管鳞癌及鼻咽癌等。在宫颈癌、胃癌等多种肿瘤的研究阶段性初步资料显示,Cadonilimab比PD-1联合CTLA-4的联合疗法相比,毒性显著降低,具有明显的安全性和疗效优势。
