Outline of Final Research Achievements

In rheumatoid arthritis (RA), the efficacy and side effects of methotrexate (MTX), the first-line drug, vary widely among individuals. We comprehensively analyzed drug metabolism-related gene single nucleotide polymorphisms (SNPs) and constructed a prediction model of MTX efficacy and side effects, including clinical factors. To enhance the external validity of the model, polyglutamylated MTX (MTX-PG) concentrations were used to extract more biological SNPs.

Academic Significance and Societal Importance of the Research Achievements

本研究は、コンパニオン診断試薬の作成において、基礎と臨床のデータを多角的に利用し、異なる研究レベルのデザインを融合させることを特徴としている。本研究によってより予測能の高い、外的妥当性の高いMTXの有効性、予測モデルを作成することができる。これにより、RAの治療の迅速な適正化・個別化が可能となり、疾患予後を改善させると考えられる。
