Romyelocel-L或可成为降低接受诱导治疗的AML患者的感染风险的新选择

急性髓系白血病 (AML) 的标准细胞毒性诱导化疗可导致中性粒细胞减少症持续时间延长,感染风险增加。Romyelocel-L是一种通用的同种异体骨髓祖细胞制品,正在被研究用于减少诱导化疗期间的感染。

共163位接受诱导化疗的新发AML患者(≥55岁)在基线(第 0 天,d0)被随机分至治疗组和对照组,其中120位可评估。治疗组受试者在第 9 天接受输注Romyelocel-L,并从第14天起开始每天输注粒细胞集落刺激因子 (G-CSF) ,对照组仅从第14天起输注G-CSF,直到中性粒细胞绝对计数恢复到500/μL

研究干预示意图

从第15-28天期间,治疗组的发热发作平均天数较对照组短(2.36 vs 3,.90, p=0.02)。与此类似,从第9-28天期间,治疗组中根据微生物学定义的感染和临床诊断的感染相比对照组表现出减少的趋势(35.6% vs 47.5%,p=0.002)。因此,治疗组中治疗感染的抗菌药或抗真菌药的使用量明显较对照组减少(第9-28天:44.1% vs 63.9%, p=0.01)。从第9-28天和第15-28天期间,治疗组接受经验性抗菌药物治疗的比例较对照组均明显降低(42.4% vs 63.9%,p=0.02;42.4% vs 62.3%,p=0.02)。

两组患者诱导化疗期间的汇总累积感染率

治疗组患者的住院时间也比对照组减少了3.2天(25.5 vs 28.7,p=0.001)。两组的缓解率和中性粒细胞计数绝对恢复的天数相似。治疗组无患者因感染而死亡,而对照组有两位患者死于感染。未观察到移植物抗宿主病。

综上所述,接受Romyelocel-L治疗的受试者的感染率、抗菌素使用率和住院率均有所降低,表明Romyelocel-L或可成为降低接受诱导治疗的AML患者的感染风险的新选择
