Q-SYMBIO試験がその疑問に明確な答えを出しました。この2年間のランダム化比較試験では、420人の心不全患者にCoQ10 300mg/日またはプラセボを投与しました。CoQ10グループでは、心血管死亡率が43%低下(9% vs. 16%、p = 0.026)し、全死亡率が42%低下(10% vs. 18%、p = 0.018)しました[9]。サプリメントとしては驚くべき数字です。
最初のヒトでの証拠は2019年に得られました。パイロット試験で、糖尿病性腎臓病を持つ9人に3日間、ダサチニブ(dasatinib)とケルセチン(1,000mg)を投与しました。脂肪組織の老化細胞が35%減少し、炎症マーカーが有意に低下し、効果は最後の投与から少なくとも11日間持続しました[12]。特発性肺線維症患者を対象とした追跡第I相試験では、このアプローチが実行可能で忍容性があることが確認されましたが、治療群でより多くの非重篤な副作用が報告されました(65件 vs. 22件)[13]。
