KRONOS、ETHOSトライアルで 3剤配合吸入剤が、他の2剤配合吸入細工に比べ、肺機能改善効果、急性増悪改善効果を認めたということになった。
「Trelegy Ellipta」の日本語表記が「テリルジー」というのもわかりにくいが・・・
3剤併合吸入剤は、名前が難しい・・・

第3相 KRONOSトライアル:

Primary endpoints for the Europe/Canada statistical analysis approach were
- FEV1 curve from 0–4 h (AUC ) for BGF MDI versus BFF MDI and BGF MDI versus BUD/FORM DPI over 24 weeks;
- 0–4 change from baseline in morning pre-dose trough FEV1 for BGF MDI versus GFF MDI
- non-inferiority of BFF MDI versus BUD/FORM DPI (margin of –50 mL from lower bound of 95% CI) over 24 weeks

ETHOSトライアル:
Breztri Aerosphere (budesonide/glycopyrronium/formoterol fumarate 320/14.4/9.6mcg) の量で、Bevespi Aerosphere (glycopyrronium/formoterol fumarate 14.4/9.6mcg):LAMA/LABA 及び PT009 (budesonide/formoterol fumarate 320/9.6mcg):ICS/LABA比較し、中等度・重症急性増悪、有意減少
Breztri Aerosphere Phase III ETHOS trial met its primary endpoint in chronic obstructive pulmonary disease

FeNO、喀痰好酸球数、末梢血好酸球との関連性を知りたい
