镰状细胞贫血(SCD)是一种常染色体显性遗传血红蛋白病,其特征是血管闭塞危象和急性疼痛。目前FDA批准了3种药物用于预防血管闭塞发作,分别为羟基脲、L-谷氨酰胺和crizanlizumab-tmca,但对于已出现疼痛性血管闭塞发作的患者,目前尚无有效的治疗手段。泊洛沙姆188(poloxamer 188)是一种常见的药物辅料,在先前的临床研究中,泊洛沙姆188治疗可缩短SCD患者疼痛性血管闭塞发作的持续时间,特别对儿童及先前接受过羟基脲治疗患者的疗效明显。

近日研究人员重新评估了泊洛沙姆188治疗SCD血管闭塞发作的疗效。

本次III期临床研究在12个国家,66家医院开展,为随机、双盲、安慰剂对照、多中心、国际试验,包括388名SCD患者(血红蛋白SS、SC、S-β0地中海贫血,或S-β+地中海贫血病),年龄范围4-65岁,伴有急性中重度疼痛作需要住院治疗。患者随机接受静脉注射泊洛沙姆188,起始剂量为1小时100mg/kg,随后连续输注12-48小时,剂量为30 mg/kg/h(n=194)或安慰剂(n=194)。研究的主要终点为从随机分组到最后一次注射阿片类药物的时间,以小时为单位。

患者平均年龄15.2岁,176名女性(45.4%),获得了384名(99.0%)患者主要结果数据,357名(92.0%)患者完成15天随访,368名(94.8%)患者完成30天随访。研究发现,组间分组后到最后一次注射阿片类药物的时间无显著差异(泊洛沙姆188组为81.8小时,安慰剂组为77.8小时;差异为4.0小时,OR=1.2)。在年龄小于16岁参与者的亚组分析中,组间分组后到最后一次注射阿片类药物的时间存在差异(泊洛沙姆188组为88.7小时,安慰剂组71.9小时;差异16.8小时, OR=1.4)。泊洛沙姆188组较常见的不良事件为高胆红素血症(12.7% vs 5.2%),而安慰剂组较常见的不良事件为缺氧(12.0% vs 5.3%)。

研究发现,对于成年及儿童镰状细胞贫血患者,静脉注射泊洛沙姆188不能缩短疼痛性血管闭塞发作的持续时间
