Обзор

Multicentre, prospective, non-randomised, single-arm, open label, mechanistic study to investigate the mechanism of action of BGF 160 on ventilation pattern complexity and variability

Вмешательства

• Препарат TRIXEO AEROSPHERE
  BGF 160 (Breztri Aerosphere™ in USA, Trixeo™ in France) Inhalation aerosol: pressurized metered dose inhaler containing a combination of budesonide (160 mcg), glycopyrrolate (9 mcg) and formoterol fumarate (4.8 mcg) as an inhalation aerosol. Oral inhalation: 2 inhalations of BGF 160 twice daily for 30 days.
