Abstract

This study aimed to evaluate influence of ethnic factors on the pharmacokinetics of orally inhaled QMF149, a novel combination of an approved longacting β2-agonist, indacaterol (Onbrez® Breezhaler® for COPD), and an approved inhaled corticosteroid, mometasone furoate (MF), (Asmanex® Twisthaler® for asthma), following multiple dose administration of QMF149 (indacaterol acetate/MF) 150/80 μg and 150/320 μg via the Breezhaler® device in healthy Japanese and Caucasian subjects. This was a single-center, openlabel, multiple-dose, two-period, complete crossover study that randomized healthy Japanese and, age and weight matched Caucasian subjects to QMF149 150/80 μg or 150/320 μg once daily (o.d.) for 14 days in each period. Pharmacokinetics (PK) were assessed up to 24 hours on days 1 and 14. 24 Japanese and 24 Caucasian healthy subjects were enrolled. Indacaterol and MF had similar PK profiles across both the doses and both ethnic groups. The maximum geometric mean ratios (90% confidence interval (CI)) for Japanese vs. Caucasian subjects for Cmax were 1.23 (1.11 - 1.38) and 1.24 (1.11 - 1.38) for indacaterol and MF, respectively. For AUC, the maximum ratios were 1.22 (1.09 - 1.36) and 1.30 (1.18 - 1.44) for indacaterol and MF, respec...Continue Reading

Asthma

This feed focuses in Asthma in which your airways narrow and swell. This can make breathing difficult and trigger coughing, wheezing and shortness of breath.

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.
