PCPに対する予防のマウスモデルにおけるSCY-078の効果の評価
この研究の目的は、比較対照として標準治療TMP-SMXを使用して、PCPの予防における経口投与されたSCY-078(イブレキサフンゲルプ)の有効性を評価することであった。
化合物の調製: SCY-078(イブレキサフンゲルプ)を、経口投与用に、0.5%メチルセルロース中で調製した。塩と水分含有量に関しては、このロットの補正係数1.37を考慮に入れた。マウスの平均体重20gに基づいて、高投与量群のマウスには、0.6mgのSCY-078BIDを投与し、中投与量群のマウスには、0.3mgのSCY-078BIDを投与し、及び、低投与量群のマウスには、0.15mgのSCY-078BIDを投与した。
図1は、6週間の処置の後のlog10平均核及び子嚢数を示している。C/Sは、ビヒクルで処置された陰性対照を示している。TMP/SMXは、トリメトプリム/スルファメトキサゾールを示している。括弧は、処置群とC/S群の間の統計的に有意な差を示している。#は、処置群とTMP/SMXの間に統計的に有意な差がないことを示している。有意性は、P値≦0.05で認められた。
SCY-078は、3種類の用量の全てにおいて、ニューモシスチス・ムリナ(P. murina)肺炎のこのマウス予防モデルにおいて非常に良好に機能した。
PCPの治療のマウスモデルにおけるSCY-078の効果の評価(早期反応)
この研究の目的は、比較対照として標準治療TMP/SMXを使用して、反応の初期の時点(7日目、14日目及び21日目)に焦点を合わせて、PCPの治療における経口投与されたSCY-078の有効性を評価することであった。
化合物の調製: SCY-078(イブレキサフンゲルプ)を、経口投与用に、0.5%メチルセルロース中で調製した。塩と水分含有量に関しては、補正係数1.37を考慮に入れた。マウスの平均体重20gに基づいて、高投与量群のマウスには、0.3mgのイブレキサフンゲルプBIDを投与し、及び、低投与量群のマウスには、0.1mgのイブレキサフンゲルプBIDを投与した。
図2は、7日間、14日間及び21日間の処置の後のlog10平均核及び子嚢数を示している。C/Sは、ビヒクルで処置された陰性対照を示している。TMP/SMXは、トリメトプリム/スルファメトキサゾールを示している。括弧は、処置群とC/S群の間の統計的に有意な差を示している。#は、処置群とTMP/SMXの間の統計的に有意な差を示している。有意性は、P値≦0.05で認められた。
SCY-078は、両方の用量レベルで、ニューモシスチス肺炎の治療のためのゴールドスタンダードであるTMP/SMXよりも7日目に子嚢負荷を低減させるのに有意に良好に機能した。
PCPの治療のマウスモデルにおけるSCY-078の効果の評価
この研究の目的は、比較対照として標準治療TMP/SMXを使用して、PCPの治療における経口投与されたSCY-078の有効性を評価することであった。
化合物の調製: SCY-078(イブレキサフンゲルプ)を、経口投与用に、0.5%メチルセルロース中で調製した。塩と水分含有量に関しては、補正係数1.37を考慮に入れた。マウスの平均体重20gに基づいて、高投与量群のマウスには、0.3mgのイブレキサフンゲルプBIDを投与し、及び、低投与量群のマウスには、0.1mgのイブレキサフンゲルプBIDを投与した。
図3は、28日間、35日間及び42日間の処置の後のlog10平均核及び子嚢数を示している。C/Sは、ビヒクルで処置された陰性対照を示している。TMP/SMXは、トリメトプリム/スルファメトキサゾールを示している。括弧は、処置群とC/S群の間の統計的に有意な差を示している。*は、処置群とTMP/SMXの間に統計的に有意な差がないことを示している。有意性は、P値≦0.05で認められた。
SCY-078は、全ての用量レベルで、ビヒクルで処置された陰性対照群(C/S)と比較して3つの全ての時点で核と子嚢の両方の負荷を有意に減少させた。
