嵌合抗原受体(CAR)T细胞在治疗B淋巴系恶性肿瘤方面已显示优异效果。CAR-T 细胞属于先进治疗药品(ATMP),其良好生产规范(GMP)要求在药品生产机构的特定条件下制备。我们团队为急性髓系白血病(AML)开发了一种新药候选物:靶向白血病干细胞表达的白细胞介素1受体辅助蛋白(IL-1RAP)的CAR,拟在I–IIa期临床试验中评估。临床前开发阶段,我们使用研究级慢病毒颗粒,在半自动封闭系统(CliniMACS Prodigy)中制备IL-1RAP CAR-T 细胞。
本研究旨在验证生产流程,并表征临床前GMP样药品。使用健康供者细胞,在9天内制备IL-1RAP CAR-T 细胞;分别采用半自动封闭系统(符合GMP样条件)或另一种研究流程,后者作为参照。
根据表型、功能和代谢分析,我们证明最终产品已具备临床应用条件。最后,在AML异种移植小鼠模型中,我们证明GMP样环境制备的IL-1RAP CAR-T 细胞能够清除肿瘤细胞并延长总生存期。
我们证明IL-1RAP CAR-T 细胞临床前GMP样制备流程在CAR-T 细胞数量、亚群表型和细胞毒功能方面符合标准监管要求。该制备流程已通过验证,可用于生产药用IL-1RAP CAR-T 细胞,支持首次I期临床试验。
Based on phenotypic, functional and metabolic analyses, we were able to show that the final product is ready for clinical use. Finally, in a xenograft AML murine model, we demonstrated that the IL-1RAP CAR-T cells generated in a GMP-like environment could eliminate tumor cells and increase overall survival.
We demonstrated that our IL-1RAP CAR-T cell preclinical GMP-like production process meets standard regulatory requirements in terms of CAR-T cell number, subpopulation phenotype and cytotoxic functionality. Our CAR-T cell production process was validated and can be used to produce medicinal IL-1RAP CAR-T cells for the first phase I clinical trial.
