摘要

研究背景本研究旨在探讨降钙素基因相关肽(CGRP)诱导的偏头痛发作对偏头痛患者接受艾伦单抗治疗效果的预测价值:共有139名偏头痛患者接受了单日实验,其中包括20分钟的CGRP输注。之后,参与者进入为期24周的艾伦单抗治疗期。主要终点是CGRP诱导的偏头痛发作对艾伦单抗疗效的预测价值,即每月偏头痛天数减少≥50%,或每月偏头痛或每月中重度头痛天数减少≥50%:在CGRP诱发偏头痛发作的参与者中,99人中有60人(61%)在使用艾伦单抗的第13-24周期间每月偏头痛发作天数减少了≥50%。相反,在输注 CGRP 没有诱发偏头痛的 25 人中,有 13 人(52%)达到了同样的终点(p = 0.498)。对CGRP敏感和不敏感的参与者每月偏头痛或每月中重度头痛天数减少≥50%之间没有明显差异(p = 0.625):我们的研究结果表明,CGRP诱发模型不能用于预测艾伦单抗的疗效。目前仍不确定这一发现是否适用于其他靶向CGRP配体的单克隆抗体或抗凝血剂:该研究已在ClinicalTrials.gov(NCT04592952)上注册。

Hypersensitivity to CGRP as a predictive biomarker of migraine prevention with erenumab.

Background: The present study aimed to investigate the predictive value of calcitonin gene-related peptide (CGRP)-induced migraine attacks for effectiveness to erenumab treatment in people with migraine.

Methods: In total, 139 participants with migraine underwent a single experimental day involving a 20-min infusion with CGRP. Following this, the participants entered a 24-week treatment period with erenumab. The primary endpoints were the predictive value of CGRP-induced migraine attacks on the effectiveness of erenumab, defined as ≥50% reduction in monthly migraine days, or ≥ 50% reduction in either monthly migraine or monthly headache days of moderate to severe intensity.

Results: Among participants with CGRP-induced migraine attacks, 60 of 99 (61%) achieved ≥50% reduction in monthly migraine days during weeks 13-24 with erenumab. Conversely, 13 of 25 (52%) where CGRP infusion did not induce a migraine achieved the same endpoint (p = 0.498). There were no significant differences between the ≥50% reduction in either monthly migraine or monthly headache days of moderate to severe intensity between CGRP-sensitive and non-sensitive participants (p = 0.625).

Conclusions: Our findings suggest that the CGRP-provocation model cannot be used to predict erenumab's effectiveness. It remains uncertain whether this finding extends to other monoclonal antibodies targeting the CGRP ligand or to gepants.Trial Registration: The study was registered at ClinicalTrials.gov (NCT04592952).
