MaxCyte宣布开展基于mRNA的CAR-T细胞疗法的I期临床试验第二批患者给药

MaxCyte公司宣布在美国开始MCY-M11的I期临床试验第二批患者的给药。MCY-M11是间皮素靶向的嵌合抗原受体(CAR)疗法,正在15名复发/难治性卵巢癌和腹膜间皮瘤患者中进行剂量递增试验,以评估MCY-M11的安全性和耐受性。

MaxCyte公司宣布在美国开始MCY-M11的I期临床试验第二批患者的给药。MCY-M11是间皮素靶向的嵌合抗原受体(CAR)疗法,正在15名复发/难治性卵巢癌和腹膜间皮瘤患者中进行剂量递增试验,以评估MCY-M11的安全性和耐受性。

MCY-M11的制造过程利用MaxCyte专有的FlowElectroporation技术将mRNA转染到新鲜(即未扩增)的外周血单核细胞(PBMC)中。这种简化、更快速的自体细胞疗法制造过程是与其他CAR技术的重要区别。

此外,该平台利用流式电穿孔而非病毒载体可控制给药剂量可重复,这一特征可能是细胞疗法成功治疗实体瘤的关键。MaxCyte的CARMA平台的另一个显着特征是将CAR作为mRNA插入细胞而不是DNA,mRNA的瞬时性质可以帮助减轻其他CAR疗法的一些安全限制。
