我们的研究结果表明,低 CD4/CD8 比值(低于三分之一)可能是 OOS 结局的预测标志物,有可能支持患者选择和治疗计划。因此,有必要使用更大的队列进行前瞻性验证。
Lisocabtagene maraleucel (liso-cel) 是一种靶向 CD19 的CAR-T 细胞疗法,用于治疗复发/难治性大 B 细胞淋巴瘤患者。
在这项涉及22名患者的回顾性研究中,我们评估了外周血CD4/CD8比值与生产过程中出现不合格(OOS)产品之间的关联。扩大准入协议允许在严格的监管监督下,尽管产品未能达到商业放行标准,仍可进行输注。
接受OOS产品的5例患者CD4/CD8比值显著更低(中位数0.22 vs. 0.46;p = 0.008)。
Lisocabtagene maraleucel (liso-cel) is a CD19-directed chimeric antigen receptor T-cell therapy for patients with relapsed or refractory large B-cell lymphoma.
In this retrospective study involving 22 patients, we evaluated the association between peripheral blood CD4/CD8 ratios and the occurrence of out-of-specification (OOS) products during manufacturing. Expanded access protocols have permitted the infusion of OOS products, despite their failure to meet commercial release criteria, under close regulatory oversight.
Five patients who received OOS products had significantly lower CD4/CD8 ratios (median 0.22 vs. 0.46; p = 0.008).
Our findings suggest that a low CD4/CD8 ratio (below one-third) may be a predictive marker for OOS outcomes, potentially supporting patient selection and treatment planning. Therefore, prospective validation using a larger cohort is warranted.
