Abstract
Description
ラットにおける薬物動態研究
θ-ディフェンシンRTD-1を上記したように、プロピレングリコールを含有する弱酸性緩衝液中に製剤し、オスおよびメスのSprague-Dawleyラットに皮下投与し、その後θ-ディフェンシンの血漿中濃度を決定した。ラットに1~4mg/kgの範囲で用量を与えた。用量の体積を0.32mL/kgで一定に保ち、したがって、θ-ディフェンシンの濃度は3.125~12.5mg/mLの範囲であった。用量は、週に3回、6週間投与された。例示的な結果を表1(オスのラットの結果を提供する)および表2(メスのラットの結果を提供する)に示す。表1および以下の表は、以下の頭字語を使用する。
CLast 定量限界を超えて測定された最終血漿濃度
Cmax 最大血漿濃度
MRTLast 分析物の血漿濃度が測定された最終時点までの平均滞留時間
TLast 定量限界を超えた最終血漿濃度が測定された時間
Tmax 最大濃度の時間。
θ-ディフェンシンRTD-1を上記したように、プロピレングリコールを含有する弱酸性緩衝液中に製剤し、23~73歳の範囲の年齢の男性および女性の対象に皮下投与し、θ-ディフェンシンの血漿中濃度を決定した。皮下注射により、20μg/kg、40μg/kg、80μg/kg、160μg/kg、または325μg/kgのθ-ディフェンシンを対象に与えた。これらの用量は、上記した動物実験において使用されたものより比較的、実質的に少ないことを理解されたい。20~80μg/kgを与えられた対象は、用量を単一の部位で送達された。より大きい量を与えられた対象は、2つの部位間でその用量を分配された。図9は、異なる処理群の経時的な血漿中のθ-ディフェンシン濃度(ng/mL)測定の典型的な結果を示す。示されるように、皮下注射時の生物学的利用能はラットに比べてヒトにおいて劇的に増大した。同様に、イヌおよびブタの動物モデルのRTD-1の皮下注射に比べて、ヒト対象の改善された結果が示された。Cmax(ng/mL)のRTD-1用量(μg/kg)への依存性を図10Aに示す。AUC0-TLastのRTD-1用量(μg/kg)への依存性の同様の研究の結果を図10Bに示す。Cmax(ng/mL)の投与された総RTD-1(mg)への依存性を図11Aに示す。AUC0-TLastの投与された総RTD-1(mg)への依存性の同様の研究の結果を図10Bに示す。AUC0-TLastおよびCmaxの両方はθ-ディフェンシン用量のおおよそ線形関数であった。意外なことに、ヒトにおいては同様の血漿濃度に達するために、試験動物で示されたものよりもはるかに低用量のθ-ディフェンシンを必要とする。発明者らは、θ-ディフェンシンの類似体で同様のまたは改善された結果が観察されるであろうことを見込む。
