白细胞介素-5受体单抗贝那利珠可有效治疗嗜酸性粒细胞综合症

2019-04-04 不详 MedSci原创

美国国立卫生研究院与阿斯利康合作的一项小型临床试验,发现哮喘药物贝那利珠单抗可显着改善了慢性免疫疾病--嗜酸性粒细胞综合症(HES)患者的健康状况。实验结果近期在线发表在新英格兰医学杂志上。

美国国立卫生研究院与阿斯利康合作的一项小型临床试验,发现哮喘药物贝那利珠单抗可显着改善慢性免疫疾病--嗜酸性粒细胞综合症(HES)患者的健康状况。实验结果近期在线发表在新英格兰医学杂志上。

HES是由血液,组织或两者中称为嗜酸性粒细胞(外部链接)的白细胞数量高于正常值引起的。大多数人每微升(μL)血液中含有0至500个嗜酸性粒细胞,但患有HES的人通常具有超过1500个嗜酸性粒细胞/μL,影响心脏、肺、皮肤、肠道、中枢神经系统和其他器官系统。并且患有该类罕见疾病的患者没有任何有效的治疗选择。

贝那利珠单抗是一种针对白细胞介素-5受体α亚基的单克隆抗体,可直接消耗嗜酸性粒细胞。

临床2期实验证实,在接受贝那利珠单抗治疗12周后,19名参与者中的17名在血液中检测不到嗜酸性粒细胞并且HES相关症状减轻,并且几乎没有副作用。

研究人员表示,需要一项更大的安慰剂对照试验以证实这些结果。
