PURPOSE:  To compare the efficacy and safety of the fluticasone/salmeterol combination product 250/50mcg BID via DISKUS (FSC) and ipratropium/albuterol 36/206mcg QID via MDI (IP/ALB) for the treatment of COPD.

METHODS:  A randomized, double-blind, parallel-group study was conducted with patients (n=365) randomized to FSC or IP/ALB for 8 weeks. Patients were ≥40 years of age with symptomatic COPD, a FEV1/FVC ≤0.7 and a FEV1 40 to 70% of predicted normal (baseline mean=43.6%), and no use of inhaled or oral corticosteriods for at least 30 days prior to randomization. Efficacy was evaluated using measures of pulmonary function, dyspnea, patient-evaluated symptoms, and albuterol use. Safety was evaluated using assessments of clincal adverse events and COPD exacerbations.

Adverse events were reported for 71 (39%) and 77 (42%) of patients in the FSC and IP/ALB groups, respectively. Exacerbations occurred in 11 (6%) FSC and 9 (5%) IP/ALB patients.CONCLUSIONS: FSC treatment resulted in greater improvements in measures of lung function, dyspnea, patient-measured daytime and nighttime symptoms, and albuterol use as compared with IP/ALB. The number of subjects reporting adverse events and COPD exacerbations was similar.

CLINICAL IMPLICATIONS:  COPD patients treated with FSC DISKUS 250/50 BID demonstrate clinically meaningful benefits in terms of both lung function improvement and symptom management. In addition, patient benefits from FSC are superior to those of IP/ALB.
