Outcomes are poor in triple-class–exposed (TCE) relapsed and refractory multiple myeloma (R/RMM). In the phase 3 KarMMa-3 trial, patients with TCE R/RMM and 2 to 4 prior regimens were randomized 2:1 to idecabtagene vicleucel (ide-cel) or standard regimens (SRs). An interim analysis (IA) demonstrated significantly longer median progression-free survival (PFS; primary end point; 13.3 vs 4.4 months; P < .0001) and higher overall response rate (ORR) with ide-cel vs SRs. At final PFS analysis (median follow-up, 30.9 months), ide-cel further improved median PFS vs SRs (13.8 vs 4.4 months; hazard ratio [HR], 0.49; 95% confidence interval [CI], 0.38-0.63). PFS benefit with ide-cel vs SRs was observed regardless of number of prior lines of therapy, with greatest benefit after 2 prior lines (16.2 vs 4.8 months, respectively). ORR benefit was maintained with ide-cel vs SRs (71% vs 42%; complete response, 44% vs 5%). Patient-centric design allowed crossover from SRs (56%) to ide-cel upon progressive disease, confounding overall survival (OS) interpretation. At IA of OS, median was 41.4 (95% CI, 30.9 to not reached [NR]) vs 37.9 (95% CI, 23.4 to NR) months with ide-cel and SRs, respectively (HR, 1.01; 95% CI, 0.73-1.40); median OS in both arms was longer than historical data (9-22 months). Two prespecified analyses adjusting for crossover showed OS favoring ide-cel. This trial highlighted the importance of individualized bridging therapy to ensure adequate disease control during ide-cel manufacturing. Ide-cel improved patient-reported outcomes vs SRs. No new safety signals were reported. These results demonstrate the continued favorable benefit-risk profile of ide-cel in early-line and TCE R/RMM. This trial was registered at www.ClinicalTrials.gov as #NCT03651128.

Ide-cel 与标准方案治疗三级暴露的复发难治性多发性骨髓瘤的比较:更新的 KarMMa-3 分析
三级暴露 (TCE) 复发难治性多发性骨髓瘤 (R/RMM) 的预后较差。在 3 期 KarMMa-3 试验中,TCE R/RMM 和 2 至 4 种既往方案的患者以 2:1 的比例随机分配到 idecabtagene vicleucel (ide-cel) 或标准方案 (SRs) 组。中期分析 (IA) 显示中位无进展生存期 (PFS;主要终点;13.3 个月 vs 4.4 个月;P < .0001) 和 ide-cel 与 SRs 相比更高的总体缓解率 (ORR)。在最终 PFS 分析(中位随访,30.9 个月)中,ide-cel 与 SRs 相比进一步改善了中位 PFS(13.8 个月 vs 4.4 个月;风险比 [HR],0.49;95% 置信区间 [CI],0.38-0.63)。无论既往治疗线的数量如何,ide-cel 与 SRs 组均观察到 PFS 获益,在既往 2 线治疗后获益最大(分别为 16.2 个月和 4.8 个月)。ide-cel 与 SRs 相比,ORR 获益得以维持(71% vs 42%;完全缓解,44% vs 5%)。以患者为中心的设计允许在疾病进展时从 SRs (56%) 交叉到 ide-cel,混淆了总生存期 (OS) 的解释。在 OS 的 IA 中,中位数为 41.4 (95% CI,未达到 [NR] 为 30.9),而 ide-cel 和 SRs 的中位数分别为 37.9 (95% CI,23.4 至 NR) (HR,1.01;95% CI,0.73-1.40);两组的中位 OS 均长于历史数据 (9-22 个月)。两项针对交叉进行调整的预先指定的分析显示,OS 偏爱 ide-cel。该试验强调了个体化桥接疗法的重要性,以确保在 ide-cel 生产过程中充分控制疾病。与 SRs 相比,Ide-cel 改善了患者报告的结局。没有报告新的安全性信号。这些结果表明,ide-cel 在早期治疗和 TCE R/RMM 中持续具有良好的获益-风险特征。该试验在 www.ClinicalTrials.gov 注册为 #NCT03651128。
