Outline of Research at the Start

片頭痛の病態で重要なカルシトニン遺伝子関連ペプチド(Calcitonin gene-related peptide; CGRP)あるいはその受容体を標的とした抗体治療(CGRP関連抗体薬)が、わが国において2021年に新たに承認となった。
本研究では、CGRP関連抗体薬を含めた片頭痛の最新治療の実態を明らかにしつつ、今後に向けての新規治療についても検討する。

Outline of Final Research Achievements

We reported real-world evidence on anti-CGRP monoclonal antibodies (CGRP mAb) at Keio University Hospital. The 50% response rate ranged from 40% to 60%, and the 100% response rate was approximately 10%. Characteristics of responders included older age, fewer failures with previous preventives, and no history of autoimmune diseases. Furthermore, a survey conducted among physician members of the Japanese Headache Society revealed that many physicians set stricter criteria for initiating CGRP mAb than those recommended in the guideline (monthly migraine days greater than or equal to 4, and failure of greater than or equal to 1 conventional preventive medication).
As part of our investigation into novel treatments, we examined the effect of the antiepileptic drug lacosamide on cortical spreading depolarization, an in vivo model of migraine. We found that lacosamide had a suppressive effect in female mice.

Academic Significance and Societal Importance of the Research Achievements

CGRP関連抗体薬に関して、わが国から初めてのリアルワールドの英文論文を含め、自施設より合計で8本の英文論文を発表、効果や安全性について報告できた。なかでも、レスポンダー解析に関する報告はアジア初の成果であり、恩恵を受けやすい患者の特徴を明らかにした点で意義が高いと考えられた。治験では検討が困難な抗体同士のスイッチに関しても報告できた。また、日本頭痛学会医師会員の調査を通じて、CGRP関連抗体薬の使用実態ならびに国内における頭痛診療の現状を体系的に明らかにすることができた。
基礎研究に関しては、今後頭痛領域においてラコサミドが新規治療となり得るか検討するうえで、重要な知見を得ることができた。
