妊娠糖尿病の既往がある女性の耐糖能異常の治療のためのセマグルチド (SERENA)
妊娠糖尿病の既往がある女性の耐糖能異常の治療のためのセマグルチド:二重盲検RCT
調査の概要
詳細な説明
患者集団:最近妊娠糖尿病(GDM)の病歴があり、産後早期に耐糖能障害が持続する女性は、特にリスクの高いグループであり、約 50% が出産後 5 年以内に 2 型糖尿病(T2DM)を発症します。 セマグルチドは、長時間作用型のグルカゴン様ペプチド-1 (GLP-1) アゴニストであり、グルコース低下効果、体重減少、心血管保護効果など、複数の有益な代謝効果があります。 GDM の既往があり、産後早期に耐糖能異常を示す女性では、セマグルチドによる治療により、プラセボと比較して長期的に 2 型糖尿病を発症するリスクが低下すると仮定しています。
介入と比較:GDMおよび耐糖能障害[空腹時血糖障害(IFG)および/または耐糖能障害(IGT)]の最近の病歴を持つ女性を対象に、セマグルチド(週1回)とプラセボを比較するための12のセンターによるベルギーの多中心二重盲検RCT ] 産後6-24週間。 参加者は、ライフスタイル対策の背景にあるセマグルチドまたはプラセボに 1/1 無作為に割り付けられます。 セマグルチドは、8週間かけて週1mgまで増量されます。 参加者は3年間フォローアップされます。 参加者は、介入の停止から3か月後に75gの経口ブドウ糖負荷試験(OGTT)を受けます。 無作為化は、産後早期の訪問時のBMIに従って層別化されます(
結果: プライマリ エンドポイントは、OGTT および/または HbA1c によって定義される T2DM の開発です。 重要な副次評価項目には、糖尿病のレスキュー療法の必要性、正常血糖への回帰、体重減少、ベータ細胞機能、インスリン抵抗性、およびメタボリック シンドロームが含まれます。 80% の検出力を達成するために、206 のサンプルサイズを計画して、研究中のフォローアップが 30% 失われると仮定して、両方のグループ間で 2 型糖尿病を発症するリスクが推定 50% 減少することを検出します。
