发表于《J Antimicrob Chemother》上的一项3期、随机、开放标签研究,考察了处于侵袭性真菌病(IFD)风险的患者,静脉(iv)泊沙康唑作为抗真菌预防的药物代谢动力学(PK)和安全性。

发表于《J Antimicrob Chemother》上的一项3期、随机、开放标签研究,考察了处于侵袭性真菌病(IFD)风险的患者,静脉(iv)泊沙康唑作为抗真菌预防的药物代谢动力学(PK)和安全性。

目的:两部分(1B/3期)、序贯、开放标签、多中心研究评估了中性粒细胞减少的AML或骨髓增生异常综合征(MDS)患者或异基因造血干细胞移植(HSCT)后处于IFD风险的患者中,iv泊沙康唑作为抗真菌预防的PK和安全性。

方法:237例患者在第1天接受了iv泊沙康唑300mg每天两次,接着4~28天接受了iv泊沙康唑300mg每天一次。至少5天后,患者随机分配到泊沙康唑口服混悬液400mg每天两次或200mg每天三次的组中,并完成了28天的治疗疗程。首要PK参数为给药间期的稳态平均浓度(Cavg)和泊沙康唑谷浓度(Cmin)。

结果:平均泊沙康唑Cmin为1320ng/mL(第6天)和1297ng/mL(第8天);稳态Cmin为1090ng/mL(第10天)。平均稳态泊沙康唑Cavg为1500ng/mL(第10或14天),在HSCT(1560ng/mL)和AML/MDS(1470ng/mL)患者中相似。最常见的治疗相关不良事件为腹泻(8%)、恶心(5%)和皮疹(5%)。3/237例患者(1%;2例证实,1例疑似)出现IFD。

结论:在该高风险人群中,iv泊沙康唑300mg的耐受性良好,造成充分的稳态全身暴露,与较低的IFD发生率相关。
