中国北京和美国麻省剑桥2018年8月9日电 /美通社/ -- 百济神州(纳斯达克代码:BGNE;港交所代码:06160),是一家处于商业阶段的生物医药公司,专注于用于癌症治疗的创新型分子靶向和肿瘤免疫药物的开发和商业化。公司今天宣布其在研抗 PD-1 抗体 tislelizumab 联合化疗作为潜在一线疗法治疗中国IIIB期或IV期鳞状非小细胞肺癌(NSCLC)患者的临床3期试验实现首例患者给药。

中国北京和美国麻省剑桥2018年8月9日电 /美通社/ -- 百济神州(纳斯达克代码:BGNE;港交所代码:06160),是一家处于商业阶段的生物医药公司,专注于用于癌症治疗的创新型分子靶向和肿瘤免疫药物的开发和商业化。公司今天宣布其在研抗 PD-1 抗体 tislelizumab 联合化疗作为潜在一线疗法治疗中国IIIB期或IV期鳞状非小细胞肺癌(NSCLC)患者的临床3期试验实现首例患者给药。

Tislelizumab 正在针对实体瘤的全球临床3期试验中进行评估,这些试验包括:作为二线治疗非小细胞肺癌(NSCLC)、一线治疗肝细胞癌,以及二线治疗食管鳞状细胞癌;两项全球临床2期试验针对先前接受过治疗的晚期肝细胞癌和复发/难治性成熟T细胞及自然杀伤细胞淋巴瘤;一项治疗中国非鳞状细胞 NSCLC 患者的关键性3期临床试验;以及两项治疗中国复发/难治性经典霍奇金淋巴瘤和作为二线治疗尿路上皮癌的关键性2期临床试验。

百济神州肿瘤免疫学首席医学官 Amy Peterson 医学博士评论道:“随着这一针对中国鳞状 NSCLC 患者的重要临床3期试验的启动,tislelizumab 作为一种后期的免疫肿瘤疗法,继续在中国和全球进行的广泛临床开发项目中取得进展。在过去三年里,我们在研究 tislelizumab 的临床试验中已经入组超过1,500位患者。我们很高兴能评估 tislelizumab 与全球范围的治疗标准紫杉醇和卡铂联用或一种尚未在中国获批但已在其他地区获得批准的新方案纳米白蛋白结合型紫杉醇(ABRAXANE®)和卡铂联用的潜在疗效。”

百济神州中国开发负责人汪来表示:“尽管最近取得了一些进展,现有的数据表明鳞状 NSCLC 患者的预后可能比其他类型肺癌患者的预后更差。最近其他检查点抑制剂联用的数据显示,免疫疗法联合含铂类与紫杉醇或纳米白蛋白结合型紫杉醇化疗可增强抗肿瘤活性并显著改善晚期鳞状 NSCLC 患者的治疗结果。这项临床3期试验,加上针对中国非鳞状 NSCLC 患者作为一线治疗的临床3期试验,将评估 tislelizumab 与化疗联合用药的效果,作为一种改善中国晚期肺癌患者治疗结果的潜在方法。这类患者的预后通常较差。”

这项临床3期、开放性、多中心试验预计将在中国大陆入组约340位IIIB期或IV期未接受化疗的鳞状 NSCLC 患者。患者将随机接受:i)卡铂和紫杉醇,ii)卡铂、紫杉醇和 tislelizumab,或 iii)卡铂、纳米白蛋白结合型紫杉醇(ABRAXANE®,百济神州在中国进行销售)和 tislelizumab。该试验设计为按RECIST 1.1版本对比由独立评审委员会(IRC)评估的无进展生存期(PFS)。关键次要终点包括总生存期、总缓解率、缓解持续时间、研究者评估的PFS、安全性和耐受性。

关于 tislelizumab

Tislelizumab (BGB-A317)是一种在研的人源性单克隆抗体,它属于一类被称为免疫检查点抑制剂的肿瘤免疫药物。Tislelizumab 由百济神州的科学家于北京发现,能与细胞表面PD-1受体结合,该受体通过防止T-细胞激活而在下调免疫系统中起到重要作用。Tislelizumab 展示出了对PD-1的高亲和性和特异性,通过Fc段改造而与目前已获批的PD-1抗体存在潜在的区别。根据临床前数据,这Fc段的改造可最大限度地减少与其他免疫细胞潜在的负面相互作用。Tislelizumab 正被开发作为单药疗法及联合疗法治疗一系列实体瘤和IBD%E8%AF%8A%E6%B2%BB%E8%BF%87%E7%A8%8B%E4%B8%AD%E7%9A%84%E8%AF%84%E4%BC%B0-Part%202" target="_blank">血液肿瘤。百济神州与新基公司达成全球战略合作关系,在亚洲(除日本)以外开发 tislelizumab 治疗实体瘤。
