Background: Recommended treatment for moderate to severe asthma is the combination of an inhaled corticosteroid and a long‐acting beta 2 ‐agonist. The present study was designed to compare a new fixed combination of extrafine beclomethasone and formoterol, with the fixed combination fluticasone and salmeterol. Methods: This was a phase III, multinational, multicentre, double‐blind, randomized, two‐arm parallel groups, controlled study. After a 2‐week run‐in period, 228 patients with moderate to severe asthma were randomized to a 12‐week treatment with either beclomethasone 100 μg plus formoterol 6 μg or fluticasone 125 μg plus salmeterol 25 μg, both delivered two inhalations b.i.d. via a pressurized metered dose inhaler. Results: The analysis of noninferiority on the primary outcome, morning peak expiratory flow in the last 2 weeks of treatment, showed no difference between groups (difference −3.32 l/min; 95% CI −17.92 to 11.28). A significant improvement from baseline in lung function, symptom score and rescue medication use was observed in both groups at all time points. Beclomethasone plus formoterol combination showed a significantly faster onset of bronchodilation when compared with fluticasone plus salmeterol with the difference maintained for up to 1 h postdosing. No differences were observed between treatments in the rate of asthma exacerbations, frequency of adverse events and overnight urinary cortisol/creatinine ratio. Conclusions: The new combination of extrafine beclomethasone plus formoterol is not inferior to the marketed combination of fluticasone and salmeterol in terms of efficacy and tolerability, with the advantage of a faster onset of bronchodilation.
