Chimeric antigen receptor (CAR) T-cell therapy fails to achieve durable responses in over 60% of relapsed/refractory (R/R) large B-cell lymphoma (LBCL) patients in the third or later line setting. After CAR-T failure, survival outcomes are heterogeneous and a prognostic model in this patient population is lacking. A training cohort of 216 patients with progressive disease (PD) after CAR-T from 12 Spanish centers was used to develop the Post-CAR Prognostic Index (PC-PI); primary endpoint was overall survival (OS) from CAR-T progression. Validation was performed in an external cohort from three different European centers (n = 204). The prognostic score incorporated five variables, assessed at time of PD to CAR-T: ECOG (> 0), hemoglobin (< 10 g/dL), LDH (≥ 2xULN), number of extranodal sites (> 1) and time from CAR-T to PD (< 4 months). Patients were classified in four risk groups with distinct OS (p-value < 0.05 in all comparisons). In the validation cohort, median OS in the low (31%), intermediate-low (26%), intermediate-high (17%) and high risk (26%) were 15.7, 7.1, 1.8 and 1.0 months, respectively (p < 0.05 in all comparisons). Results were consistent following adjustment for subsequent treatment. In the external cohort, the PC-PI showed a C-statistic of 0.79 (95%CI 0.76–0.82), outperforming IPI and R-IPI. In conclusion, the PC-PI score is a novel tool for OS prediction and could facilitate risk-adapted management of LBCL patients relapsing after CAR T-cells. Additionally, these results will help stratification and interpretation of trials and real-world data incorporating CART-exposed patients. The Post-CAR Prognostic Index (PC-PI) is a tool to inform on overall survival after CAR T-cell progression in large B-cell lymphoma patients. The PC-PI can help risk-stratification and interpretation of trials and real-world data of regimens incorporating CART-exposed patients.

三线或后线治疗 CAR-T 进展后大 B 细胞淋巴瘤患者 CAR 后预后指数的开发和验证
嵌合抗原受体 (CAR) T 细胞疗法在超过 60% 的复发/难治性 (R/R) 大 B 细胞淋巴瘤 (LBCL) 患者中未能在第三线或更晚的治疗中实现持久反应。CAR-T 失败后,生存结局存在异质性,并且缺乏该患者群体的预后模型。来自西班牙 12 个中心的 216 名 CAR-T 后疾病进展 (PD) 患者的训练队列用于开发 CAR 后预后指数 (PC-PI);主要终点是 CAR-T 进展的总生存期 (OS)。在来自三个不同欧洲中心的外部队列中进行验证 (n = 204)。预后评分包括 5 个变量,在 PD 到 CAR-T 时进行评估:ECOG (> 0)、血红蛋白 (< 10 g/dL)、LDH (≥ 2xULN)、结外部位数量 (> 1) 和从 CAR-T 到 PD 的时间 (< 4 个月)。将患者分为 4 个具有不同 OS 的风险组 (p 值 < 0.05 在所有比较中)。在验证队列中,低 (31%) 、中低 (26%) 、中高 (17%) 和高风险 (26%) 的中位 OS 分别为 15.7 、 7.1 、 1.8 和 1.0 个月 (p < 0.05 在所有比较中)。调整后续治疗后结果一致。在外部队列中,PC-PI 显示 C 统计量为 0.79 (95% CI 0.76-0.82),优于 IPI 和 R-IPI。总之,PC-PI 评分是一种预测 OS 的新工具,可促进 CAR T 细胞后复发的 LBCL 患者的风险适应管理。此外,这些结果将有助于对纳入 CART 暴露患者的试验和真实世界数据进行分层和解释。CAR 后预后指数 (PC-PI) 是一种告知大型 B 细胞淋巴瘤患者 CAR T 细胞进展后总生存期的工具。 PC-PI 可以帮助对纳入 CART 暴露患者的试验和方案的真实世界数据进行风险分层和解释。
