Cellectis公布了提高CAR T细胞治疗安全性和预防CRS的新方法


2019-02-26 不详 网络

Cellectis是一家生物制药公司,专注于开发基于同种异体基因编辑的CAR T细胞(UCART)的免疫疗法,近日在《生物化学杂志》发表了一项最新研究,鉴定了由嵌合抗原受体(CAR)T细胞分泌的粒细胞巨噬细胞集落刺激因子(GMCSF)是促进细胞因子释放综合征(CRS)的关键因子,Cellectis利用这些发现来制定创新的工程策略,为开发更安全的UCART产品铺平了道路。

创新项目负责人Mohit Sachdeva博士说:“CAR T细胞疗法在血液系统恶性肿瘤中达到了很高的完全缓解率,然而,这种活性药物可能显示出危及生命的炎症副作用,包括需要解决的CRS和神经毒性。我们的工程策略规避了这种有毒的副作用,并推出了更安全、且同样有效的UCART细胞,以改善患者在治疗期间的生活质量
