智通财经APP讯,和铂医药-B(02142)发布公告,辉瑞(集团的合作伙伴)将于2025年美国临床肿瘤学会(ASCO)年会上发表同类首创靶向间皮素(MSLN)之抗体偶联药物 (ADC) MesoC2 (HBM9033/PF-08052666)的首次人体1期临床研究设计。
MesoC2最初由公司全资附属公司诺纳生物(苏州)有限公司(诺纳生物)利用其专有的Harbour Mice®平台及一体化ADC平台自主研发,并于2023年12月通过全球许可协议授权予辉瑞。该ADC目前正在开展一项针对多种晚期实体瘤患者的1期开放标签研究。
辉瑞将于本年度ASCO年会上展示的临床研究信息如下:
一项评估抗体偶联药物(ADC) MesoC2 (PF-08052666)在晚期实体瘤患者中安全性及耐受性的1期研究
摘要编号:TPS3163;展示形式:壁报;壁报编号:475a ;会议名称:壁报展示-新兴疗法-分子靶向药物与肿瘤生物学 ;会议日期:2025年6月2日
展示核心要点:
MesoC2是由人源IgG1抗MSLN单克隆抗体通过可裂解三肽连接子与拓扑异构酶1抑制剂(TOP1)载荷偶联而成的ADC(平均抗体-药物偶联比为8)。
MesoC2在体外试验及异种移植模型中展示出显著的抗肿瘤疗效,并在食蟹猴中显示出可接受的安全性特征。
该项1期试验(NCT06466187)将按剂量递增、剂量优化和队列扩展开展,对最多365例患者进行评估MesoC2的安全性、耐受性、药代动力学、药效动力学及基于RECIST v1.1标准的初步疗效。
