Lancet respirat med:吡非尼酮加用西地那非对晚期特发性肺纤维化无治疗益处

西地那非对晚期特发性肺纤维化(IPF)患者是否存在肺动脉高压预后不良的风险尚不确定。本研究旨在评估西地那非联合吡非尼酮用于有3组肺动脉高压风险的晚期IPF患者的疗效和安全性。

西地那非对晚期特发性肺纤维化(IPF)患者是否存在肺动脉高压预后不良的风险尚不确定。本研究旨在评估西地那非联合吡非尼酮用于有3组肺动脉高压风险的晚期IPF患者的疗效和安全性。

这是一项多中心、国际性、双盲、随机、安慰剂为对照的2b期试验,招募40-80岁的晚期IPF患者,要求有3组肺动脉高压风险因素(平均肺动脉压≥20 mm Hg和肺动脉楔压≤15 mm Hg或3组肺动脉高压中高可能性)。1:1随机分组接受西地那非(片剂,20 mg,3/日)或安慰剂+吡非尼酮(胶囊,801 mg,3/日)持续治疗52周。复合主要终点是52周后的病程进展、呼吸相关住院或全因死亡率。

2017年1月13日-2018年8月30日,共筛选了247位患者,其中177位被随机分至两组:西地那非组 88位、安慰剂组 89位。52周后两组中发生病程进展的患者比例没有明显差异(西地那非组 vs 安慰剂组:73% vs 70%)。需紧急治疗的重度不良反应见于西地那非组的54位(61%)患者和安慰剂组的55位(62%)患者。两组还分别发生了22例(25%)和26例(29%)需紧急治疗的不良反应导致的死亡。

总结:对于有肺动脉高压风险的晚期IPF患者,与单用吡非尼酮相比,加用西地那非没有提供治疗益处。两种治疗方式未出现新的安全问题。
