Background: The combination of tiotropium and fluticasone propionate/salmeterol (FSC) is commonly used to treat chronic obstructive pulmonary disease (COPD), but no study had evaluated the effectiveness of tiotropium plus FSC with 250 μg of fluticasone propionate. Our aim was to assess whether tiotropium (18 μg once daily) plus FSC (250/50 μg twice daily) provides better clinical outcomes compared to tiotropium monotherapy. Methods: In this 24-week, randomized, open label, multicenter two-arm parallel study, 479 patients received tiotropium plus FSC (n = 237) or tiotropium alone (n = 242). Results: After 24 weeks of treatment, the triple-inhaled treatment group had a significant improvement in pre-bronchodilator FEV 1 (L) compared to the tiotropium-only group (0.090 L vs. 0.038 L; P = 0.005). Regarding health-related quality of life, the mean change in total score on the St. George's Respiratory Questionnaire for COPD patients (SGRQ-C) was -6.6 points in the tiotropium plus FSC group, but -1.5 points in the tiotropium-only group (P = 0.001). In the subgroup of GOLD stage II patients with COPD, treatment with tiotropium plus FSC also improved FEV 1 compared to tiotropium alone (0.088 L vs. 0.030 L; P = 0.011) and improved the total SGRQ-C score than tiotropium alone (-4.5 points vs. -1.0 points, respectively). This triple-inhaled treatment approach did not induce more adverse events, such as pneumonia. Conclusion: Over the course of 24 weeks, FSC (250/50 μg twice daily) added to tiotropium provided greater improvement in lung function and quality of life in patients with COPD (FEV 1 ≤ 65%) than tiotropium alone.
