ABSTRACT
The study aim was to investigate the pharmacokinetics of single high doses and repeated therapeutic doses of fluticasone furoate (FF) and batefenterol (BAT; a bifunctional muscarinic antagonist and ß2 -agonist) administered in combination (BAT/FF) or as monotherapy. In this open-label, 6-period, crossover study of 48 subjects, the treatment sequences were (1) single high-dose BAT/FF 900/300 µg followed by repeated therapeutic doses of BAT/FF 300/100 µg (once daily for 7 days); (2) single high-dose BAT 900 µg administered concurrently with FF 300 µg; (3) single high-dose BAT 900 µg followed by repeated therapeutic-dose BAT 300 µg; (4) single high-dose FF 300 µg followed by repeated therapeutic-dose FF 100 µg; (5) single high-dose FF 300 µg (magnesium stearate); and (6) single high-dose FF/vilanterol 300/75 µg. Plasma FF area under the plasma drug concentration-time curve (AUC) was reduced after single high-dose BAT/FF versus FF alone (ratio of geometric least squares means 0.79; 90% confidence interval 0.75-0.83). After repeat dosing, FF AUC at the lower therapeutic dosage was similar for BAT/FF and FF (primary endpoint; AUC geometric least squares means 1.03). Adverse events were minor, the most common being cough. These data support the feasibility of developing BAT/inhaled corticosteroid triple therapy in a single inhaler.
