まとめ
アルツハイマー病臨床試験の募集は、関心の欠如や厳格な適格基準などの障壁に直面しています。これらに対応することで、特にADRD研究における多様な高齢者の登録を改善できます。
科学分野:
- 老年医学; 臨床試験; 神経科学
背景:
- アルツハイマー病および関連認知症(ADRD)臨床試験は、特に過小評価されている集団において、重大な募集上の課題に直面しています。
- これらの課題は、試験の遅延、コストの増加、および科学的妥当性の低下につながります。
研究 の 目的:
- ADRD臨床試験における募集への参加者関連および研究関連の障壁を調査すること。
- 将来の募集戦略のために修正可能な障壁を特定すること。
主な方法:
- 多様な高齢者が関与した2つのADRD臨床試験からのスクリーニング除外データの分析。
- 独立した評価者によるスクリーニング除外理由の体系的なレビューと分類。
- スクリーニング除外の可能性に対する参加者の特性の影響を決定するための統計分析。
主要な成果:
- スクリーニング除外者の62%は参加者関連(例:関心の欠如、スケジュールの都合、病気)でした。
- 研究関連の理由には、不適格性(57%)、研究負担(19%)、同時登録(14%)が含まれていました。
- 女性はより不信感を報告しました。マイノリティの高齢者は、適格基準により不均衡にスクリーニング除外されました。
結論:
- 特定された修正可能な参加者関連の障壁には、認識の欠如と信頼できるメッセンジャーの必要性が含まれます。
- 研究関連の戦略には、制限的な適格基準の再検討とインセンティブの提供が含まれるべきです。
- 包括的なADRD試験を設計するためには、社会的アイデンティティの交差性を調査することが重要です。
