西达本胺(Chidamide;商品名: 爱谱沙®/Epidaza®)是公司独家发现的全新机制新分子实体药物,是全球首个亚型选择性组蛋白去乙酰化酶(HDAC)抑制剂,属于表观遗传调控类药物。西达本胺是国家863及“重大新药创制”专项成果。

 

西达本胺作用于表观遗传相关靶点组蛋白去乙酰化酶(第I类的1、2、3亚型和第IIb类的10亚型)。组蛋白去乙酰化酶(HDAC)是一类对染色体的结构修饰和基因表达调控发挥重要作用的蛋白酶, 西达本胺作为HDAC抑制剂,通过抑制HDAC的生物学活性产生作用,并由此产生针对肿瘤发生的多条信号传递通路基因表达的改变(即表观遗传改变)。具体而言,西达本胺的一般性作用机理主要包括:①直接抑制肿瘤细胞周期并诱导细胞凋亡; ②诱导和激活自然杀伤细胞(NK)和抗原特异性细胞毒T细胞(CTL)介导的肿瘤杀伤作用;③抑制肿瘤细胞的表型转化及微环境的促耐药/促转移活性。 

 

西达本胺已被纳入国家医保药品目录常规乙类管理。该药在中国大陆和中国澳门地区已获批外周T细胞淋巴瘤(PTCL)、乳腺癌、弥漫大B细胞淋巴瘤(DLBCL)适应症;在日本已获批成人T细胞白血病(ATL)、PTCL适应症;在中国台湾地区已获批乳腺癌适应症。

 

公司及合作伙伴正在全球范围内探索“HDACi+IO”作为下一代肿瘤免疫治疗药物组合的开发。其中,针对黑色素瘤的跨国多中心III期临床试验已达到主要终点,针对结直肠癌的中国III期临床试验已完成患者招募。全球首个表观免疫偶联药物(EIMAC,Epigenetic Immune-Modulating Antibody Conjugate)NW001的临床试验申请已获得受理。
