A Single-dose, Randomised, Crossover, Placebo-controlled Study Assessing Two Fixed-dose Combinations of Inhaled Long-acting Beta-agonist and Corticosteroid

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.
