Carfilzomib use has been extensively associated with cardiovascular toxicity; the risk with ixazomib, a novel oral proteasome inhibitor, is underreported and no large comparative analysis is available.
We conducted a retrospective cohort study utilizing the TriNetX platform to compare toxicity outcomes among multiple myeloma patients who received lenalidomide, dexamethasone, and ixazomib (IRd) or carfilzomib (KRd).
After propensity-score-matching 478 patients from each cohort, the onset of new heart failure (HR 0.25; < 0.001) and arrhythmias (HR 0.57; = 0.014) at 6 months were significantly lower with IRd while overall survival at 3 years was similar ( = 0.50).
IRd is associated with a significantly lower risk of cardiac toxicities compared to KRd.
卡非佐米的使用与心血管毒性广泛相关;新型口服蛋白酶体抑制剂伊沙佐米的相关风险报道较少,且尚无大型对比分析。
我们利用TriNetX平台进行了一项回顾性队列研究,以比较接受来那度胺、地塞米松和伊沙佐米(IRd)或卡非佐米(KRd)的多发性骨髓瘤患者的毒性结果。
在对每个队列中的478例患者进行倾向评分匹配后,IRd组在6个月时新发心力衰竭(HR 0.25;<0.001)和心律失常(HR 0.57;=0.014)的发生率显著较低,而3年总生存率相似(=0.50)。
与KRd相比,IRd发生心脏毒性的风险显著更低。
