Résumé
QMF149 is an inhaled fixed-dose combination of indacaterol acetate and mometasone furoate (MF) delivered via Breezhaler®, under development for once-daily treatment of asthma. MF delivered via Twisthaler® is approved as Asmanex® Twisthaler® for the treatment of asthma. Bridging of MF delivered via Twisthaler® to MF delivered via Breezhaler® was undertaken as part of QMF149 development to enable dose comparisons between the devices. Pharmacokinetics (PK) of MF were characterized in two studies; a single dose PK study in healthy volunteers and a pharmacokinetic/pharmacodynamic (PK/PD) study in asthma patients. The PK study in healthy volunteers evaluated the PK of single doses of MF via Breezhaler® (50-400 μg) and compared systemic exposure of MF following administration via Breezhaler® and Twisthaler® 400 μg (2 inhalations of 200 μg). The study in patients with asthma characterized the MF PK profile following once-daily inhalation of MF via Breezhaler® and Twisthaler® devices for 4 weeks. In the open-label, single-dose, crossover study, healthy subjects sequentially received MF via Twisthaler® (400 μg, medium-dose inhaled corticosteroid [ICS]) and escalating doses via Breezhaler® (50, 100, 200, 400 μg). PK data were obtained up to 72 h post-dose. In the double-blind, double-dummy, parallel-group study, asthma patients were randomised to receive either MF 80 μg (low-dose ICS) or 320 μg (high-dose ICS) via Breezhaler®, or 200 μg (low-dose ICS) or 800 μg (2 inhalations of 400 μg; high-dose ICS) via Twisthaler® once daily for 4 weeks. PK sampling was performed on Days 1 and 28 at pre-dose and up to 24 h post-dose. In the healthy volunteer PK study, 20 healthy subjects completed all treatments. Dose-normalised AUC PK characterization in a healthy volunteer PK study and subsequently an asthma study enabled selection of 80 μg (low), 160 μg (medium), and 320 μg (high) delivered via Breezhaler® as MF doses comparable to the 200 μg, 400 μg and 800 μg doses delivered by Twisthaler®, respectively, as part of QMF149 formulation development.

BACKGROUND
QMF149 is an inhaled fixed-dose combination of indacaterol acetate and mometasone furoate (MF) delivered via Breezhaler®, under development for once-daily treatment of asthma. MF delivered via Twisthaler® is approved as Asmanex® Twisthaler® for the treatment of asthma. Bridging of MF delivered via Twisthaler® to MF delivered via Breezhaler® was undertaken as part of QMF149 development to enable dose comparisons between the devices. Pharmacokinetics (PK) of MF were characterized in two studies; a single dose PK study in healthy volunteers and a pharmacokinetic/pharmacodynamic (PK/PD) study in asthma patients.
OBJECTIVES
The PK study in healthy volunteers evaluated the PK of single doses of MF via Breezhaler® (50-400 μg) and compared systemic exposure of MF following administration via Breezhaler® and Twisthaler® 400 μg (2 inhalations of 200 μg). The study in patients with asthma characterized the MF PK profile following once-daily inhalation of MF via Breezhaler® and Twisthaler® devices for 4 weeks.
METHODS
In the open-label, single-dose, crossover study, healthy subjects sequentially received MF via Twisthaler® (400 μg, medium-dose inhaled corticosteroid [ICS]) and escalating doses via Breezhaler® (50, 100, 200, 400 μg). PK data were obtained up to 72 h post-dose. In the double-blind, double-dummy, parallel-group study, asthma patients were randomised to receive either MF 80 μg (low-dose ICS) or 320 μg (high-dose ICS) via Breezhaler®, or 200 μg (low-dose ICS) or 800 μg (2 inhalations of 400 μg; high-dose ICS) via Twisthaler® once daily for 4 weeks. PK sampling was performed on Days 1 and 28 at pre-dose and up to 24 h post-dose.
RESULTS
In the healthy volunteer PK study, 20 healthy subjects completed all treatments. Dose-normalised AUC
CONCLUSION
PK characterization in a healthy volunteer PK study and subsequently an asthma study enabled selection of 80 μg (low), 160 μg (medium), and 320 μg (high) delivered via Breezhaler® as MF doses comparable to the 200 μg, 400 μg and 800 μg doses delivered by Twisthaler®, respectively, as part of QMF149 formulation development.
