NEJM:PDE4B抑制剂BI 1015550 可防止特发性肺纤维化患者肺功能下降

2022-06-14 zhangfan MedSci原创

PDE4B抑制剂BI1015550单独使用或联合抗纤维化药物可有效防止特发性肺纤维化患者肺功能下降,且安全性良好。

特发性肺纤维化(IPF)是一种进行性、不可逆的肺部疾病,患者死亡率很高。目前,已有两种药物——Nintedanib和Pirfenidone上市,其可以减缓但不能阻止纤维化进展。磷酸二酯酶4(PDE4)抑制与抗炎和抗纤维化相关,其中PDE4B亚型抑制可能对IPF治疗有益。近日研究人员公布了PDE4B抑制剂BI 1015550 II期临床的研究结果。

本次II期双盲、安慰剂对照试验中,研究人员考察了BI 1015550对特发性肺纤维化患者的疗效和安全性。患者随机接受BI 1015550,剂量为18 mg,每日两次或安慰剂。研究的主要终点是12周时用力肺活量(FVC)较基线的变化。

共有147名患者参与研究。在没有使用抗纤维化药物的患者中,BI 1015550组FVC的平均变化为5.7 ml,安慰剂组为-81.7 ml(平均差异88.4 ml)。在使用抗纤维化药物的患者中,BI 1015550组FVC的平均变化为2.7 ml,安慰剂组为-59.2 ml(平均差异62.4 ml)。BI 1015550组最常见的不良事件是腹泻,共有13名患者因不良事件停止治疗。组间严重不良事件率相似。

研究认为,PDE4B抑制剂BI1015550单独使用或联合抗纤维化药物可有效防止特发性肺纤维化患者肺功能下降,且安全性良好。
