Indacaterol/Glycopyrronium/Mometasone: A Review in Asthma

Indacaterol/glycopyrronium/mometasone (Enerzair^® Breezhaler^®) is a fixed-dose combination of the long-acting β₂ agonist (LABA) indacaterol, the long-acting muscarinic antagonist (LAMA) glycopyrronium and the inhaled corticosteroid (ICS) mometasone furoate (hereafter referred to as mometasone) delivered via a capsule-based dry-powder inhaler. It is approved in the EU for use as maintenance treatment in adult patients with inadequately controlled asthma who had experienced one or more exacerbations in the previous year. The approval also includes an optional digital companion (sensor and app) that provides data on the patient's use of the inhaler. In the 52-week IRIDIUM trial in patients with inadequately controlled asthma, indacaterol/glycopyrronium/mometasone improved lung function to a greater extent than LABA/ICS combinations (i.e. indacaterol/mometasone and fluticasone propionate/salmeterol), but superiority in Asthma Control Questionnaire 7 score was not shown. In the 24-week ARGON trial, indacaterol/glycopyrronium/mometasone via a single inhaler was non-inferior to fluticasone propionate/salmeterol + tiotropium via two inhalers with regard to Asthma Quality of Life Questionnaire score. Indacaterol/glycopyrronium/mometasone was generally well tolerated, and the most common adverse events were respiratory in nature. In conclusion, combination therapy with indacaterol/glycopyrronium/mometasone represents a valuable option for the maintenance treatment of asthma, with the convenience of once-daily administration via a single inhaler.
