据Biohaven Pharmaceutical报告称,针对急性偏头痛治疗的口服CGRP受体拮抗剂rimegepant(以前称为BHV-3000)的两项III期临床研究符合其共同主要疗效终点。Rimegepant预计于2019年获得美国FDA的批准。

Biohaven Pharmaceutical报告称,针对急性偏头痛治疗的口服CGRP受体拮抗剂rimegepant(以前称为BHV-3000)的两项III临床研究符合其共同主要疗效终点。Rimegepant预计于2019年获得美国FDA的批准。

BHV3000-301BHV3000-302研究中,共有1080名偏头痛患者被随机分配接受rimegepant或安慰剂治疗。试验的主要目标是在治疗后两小时内用药组的疼痛自由度和无症状自由度优于安慰剂组,而次要终点包括疼痛症状的缓解。

结果显示,在两项研究中,用药组的疼痛自由度分别为19.2%和19.6%,安慰剂组分别为14.2%和12%。此外,在两项试验中用药组患者的无症状自由度分别为36.6%和37.6%,而安慰剂组分别为27.7%和25.2%。与此同时,55%以上的患者在两个小时后都获得了疼痛症状的缓解。

Biohaven进一步指出,实验性药物与研究中的安慰剂相比并不存在增加肝脏毒性的风险,因为只有一名接受rimegepant治疗的患者的肝酶升高超过正常上限的三倍。同时,没有患者显示其肝酶升高超过正常上限的五倍,十倍或二十倍。该公司表示,这些试验的全部数据将在未来的研究会议上公布。
