Abstract: Introduction: A well-designed, protocol-driven randomized controlled trial (RCT) has demonstrated the efficacy of fluticasone furoate-umeclidinium-vilanterol (FF-UMEC-VI) in patients with asthma, but there is a lack of real-world data that can be used to translate the results of the RCT into clinical practice. This study evaluated the efficacy of switching the therapy from inhaled corticosteroid-long-acting β2-agonists (ICS-LABAs) to FF-UMEC-VI at the equivalent corticosteroid dose in a real-world setting. Methods: A prospective, three-month, open-label, parallel-group, switching therapy trial was performed in patients with symptomatic asthma under routine management. Patients receiving low-to-medium doses of ICS-LABAs were switched to FF-UMEC-VI (100-62.5-25 µg, once daily) (T100 group), and patients receiving a high dose of ICS-LABAs were switched to FF-UMEC-VI (200-62.5-25 µg, once daily) (T200 group). The primary outcome was the change from baseline in forced expiratory volume in 1 s (ΔFEV1) at week 12, and the secondary outcomes were the improvement in fractional exhaled nitric oxide (FeNO), the asthma symptoms evaluated using the asthma control test (ACT), and the cough severity evaluated using the visual analog scale (VAS). Results: < 0.05). Cough VAS also significantly decreased but did not reach a minimal clinically important difference. Conclusions: In patients with symptomatic asthma showing insufficient control, an improvement in the asthma symptoms was observed after switching to FF-UMEC-VI at the equivalent corticosteroid dose, accompanied by an improvement in FEV1.
