The EFFECT (Efficacy of Fluticasone propionate/FormotErol in COPD Treatment) trial is a Phase III, 52-week, randomized, double-blind study to evaluate the efficacy and safety of two doses of fluticasone propionate/formoterol compared to formoterol monotherapy in COPD patients with FEV1 ≤50% predicted and a history of exacerbations. The primary endpoint is the annualized rate of moderate and severe exacerbations. Secondary endpoints include pre-dose FEV1, EXACT-PRO (EXAcerbations of Chronic pulmonary disease Tool – Patient-Reported Outcome)-defined exacerbations, St George’s Respiratory Questionnaire for COPD, COPD Assessment Test, and EXACT-Respiratory Symptoms total score. Lung-specific biomarkers (surfactant protein D and CC chemokine ligand-18) will be measured in a subset of patients to explore their relationship to other clinical indices in COPD and their predictive utility. Pneumonia will be diagnosed per criteria defined by the British Thoracic Society community acquired pneumonia guideline, primarily by radiological confirmation and, additionally, using clinical criteria when a chest radiograph cannot be obtained. Serial measurements of serum potassium, vital signs and electrocardiograms, 24-hour Holter monitoring, and 24-hour urinary cortisol measurement will be performed in a subset of patients in addition to conventional safety assessments.
