    Abstract:
    PURPOSE: Triple therapy using salmeterol/fluticasone propionate (FP) and tiotropium bromide is commonly used to treat chronic obstructive pulmonary disease (COPD), but sparse efficacy data exist in COPD patients with fewer symptoms and with a lower dose of inhaled corticosteroid in Japanese patients. The effects of of salmeterol/fluticasone propionate 50/250 μg (SFC250) twice daily plus tiotropium 18 μg (TIO) once daily and individual treatments on lung function were compared. PATIENTS AND METHODS: Fifty three Japanese COPD patients participated in this randomized, double-blind, double-dummy, Williams square design crossover study. Lung function was assessed by plethysmography and spirometry. RESULTS: The primary endpoint of postdose specific airway conductance area under the curve (AUC0-4h) on day 28 was significantly higher following SFC250 + TIO (0.854) compared with TIO (0.737, 15.8%) and SFC250 (0.663, 28.8%) alone. SFC250 + TIO significantly improved trough forced expiratory volume in 1 second from baseline versus TIO (0.161 L, P<0.001) and SFC250 (0.103 L, P=0.008). SFC250 + TIO significantly improved residual volume compared with TIO (P<0.001) and SFC250 (P=0.003) on day 28. Nonsignificant improvements were seen in trough inspiratory capacity, total lung capacity, and thoracic gas volume. There was no mean change seen in rescue medication. CONCLUSION: Triple therapy using SFC250 + TIO was well tolerated and gave a greater improvement in bronchodilation compared with TIO and SFC250 alone in Japanese patients with COPD. There was improvement in few symptoms, but no mean change was seen in patient-reported outcomes measured by rescue medication use.
