Description
心室QT間隔の再分極持続時間を制御するための組成物及び方法が本明細書中で開示される。本発明の方法は、修正されない場合に心筋細胞活動電位における再分極の延長、トルサード・ド・ポアンツ及びQT延長症候群を誘発し得る先天的欠損の修正又は治療薬による機能的介入を、それを必要とする対象に投与することを含む。本発明は、非経口投与(静脈内又は皮下)投与前にQT延長薬をリポソームと結合させるか、あるいは、QT延長の高いリスクを有することを知られている1若しくは2以上の治療薬の前若しくは治療薬と同時、又は毒物注入の直後に空リポソームを投与することのいずれかからなる。本発明の知見は、クルクミン及び他のQT延長剤の有害作用が、リポソームクルクミン及び空リポソームのボルテックスされた混合物を用いることで用量依存的に抑止されることを示す。
クリゾチニブ(Xalkori(登録商標))及びニロチニブ(Tasigna(登録商標))はそれぞれ、非小細胞肺がん及び慢性骨髄性白血病の処置のために承認されたチロシンキナーゼ阻害薬である。両方とも、ヒト及び動物におけるQT延長をもたらすことが示されている。リポソームは、ヒトether−a−go−go関連遺伝子(hERG)によりコード化されたIKr(KV11.1)チャネルに対する薬剤誘発性効果を改善することが示されている。本研究は、リポソームもIKrチャネルに対するクリゾチニブ及びニロチニブの効果を低下させるかどうかを判定するために行った。hERGで安定的にトランスフェクトしたヒト胎児由来腎臓(HEK)293細胞を使用した標準インビトロIKrアッセイにおいて、クリゾチニブ及びニロチニブを試験した。用量反応を判定し、50%阻害濃度(IC50s)を算出した。HEK293細胞をリポソームと混合したクリゾチニブ及びニロチニブで処理した場合、これらの2つの薬剤のIKrチャネル阻害効果に著しい減少がみられた。リポソーム被包性QT延長薬の使用、又はこれらの薬剤をリポソームと混合するだけで、これらの心臓性の傾向が低下することが見出された。
ウサギの心臓の心臓電気生理学的パラメータに対するクリゾチニブ及びリポソーム+クリゾチニブの効果に関するインビボでの評価。本研究の目的は、ウサギ心臓の心臓電気生理学的(PR、QRS、RR、QT及びQTc間隔)パラメータに対するクリゾチニブ及びリポソーム+クリゾチニブのインビボでの効果を定量化することである。
ウサギの心臓の心臓電気生理学的パラメータに対するニロチニブ及びリポソーム+ニロチニブのインビボでの効果に関するインビボでの評価。本研究の目的は、ウサギの心臓からの心臓電気生理学的(PR、QRS、RR、QT及びQTc間隔)パラメータに対するニロチニブ及びリポソーム+ニロチニブのインビボでの効果を定量化することである。
クリゾチニブは、11及び56μMの濃度で、それぞれ、20mVでのIKrテール電流密度の57及び89%の阻害を引き起こしたことが見出された(図18A)。対応のあるステューデントのt検定は、ベースライン時並びに11及び56μMのクリゾチニブの存在下で測定した正規化電流密度の差異が、統計学的に有意な所定の閾値(p≦0.05)に達したことを示した。IC50はクリゾチニブ単独で8.9μMであった(表35)。クリゾチニブをリポソームと9:1の比率で混合した場合、56μMの最高濃度のクリゾチニブのみがベースラインに比し統計的に有意な阻害(59%)に達した。IC50は44μMであった。11μMでのリポソーム+クリゾチニブは、IKrテール電流密度に何ら効果を及ぼさなかった。56μMでのリポソーム+クリゾチニブは、ベースラインに比しIKrテール電流密度に何ら有意な効果を及ぼさなかった。一方、11及び56μMでのクリゾチニブとリポソーム+クリゾチニブとの間の電流密度を比較すると、リポソームと混合した場合、クリゾチニブの効果である有意な阻害がみられた。リポソーム単独は、IKrテール電流密度に何ら効果を及ぼさなかった(図18A)。
クリゾチニブは、11及び56μMの濃度で、QTc間隔の用量依存的な延長を引き起こした(図30A)。クリゾチニブをリポソームと9:1の比率で混合すると、クリゾチニブ誘発性QTc延長の有意な阻害をもたらした。ニロチニブもまた、14及び28μMの濃度で、QTc間隔の用量依存的な延長を引き起こした(図30B)。クリゾチニブの場合と同様、ニロチニブをリポソームと混合すると、ニロチニブ誘発性QTc延長の有意な阻害をもたらした。シサプリド陽性対照は、QTc間隔の予想された延長を示した。
10分間にわたって静脈内注入により1、2及び3mg/kgでクリゾチニブを投与し、その後15分間維持用量を投与したウサギは、QT間隔の用量依存的な延長を示した(図23)。クリゾチニブでの処理5分前、リポソームを注入すると、クリゾチニブ誘発性QTc延長の有意な阻害がもたらされた。10分間にわたって静脈内注入により2、4及び5.5mg/kgでニロチニブを投与し、その後15分間維持用量を投与したウサギは、QT間隔の用量依存的な延長を示した(図28)。クリゾチニブの場合と同様、ニロチニブでの処理5分前、リポソームを注入すると、ニロチニブ誘発性QTc延長の有意な阻害がもたらされた。
