简要总结
The purpose of this study is to assess the the ability of a single dose of LAS40468 administered via Genuair® and a single dose of salmeterol/fluticasone propionate (Seretide®) administered via Accuhaler to produce bronchodilation (opening of the airways) and the safety and tolerability of the treatments
详细描述
This is a Phase 1, randomised, double-blind, double-dummy, cross-over trial to assess the bronchodilation effect of a single dose of LAS40468 and a single dose of salmeterol/fluticasone propionate (Seretide®) administered to adult patients with stable asthma.
The study will consist of a screening visit and treatment periods of approximately 13 hours separated by washout periods of 7 to 14 days from the time of Investigational Medicinal product (IMP) administration.
