Participants were current or former smokers aged 40–80 years, with a history of COPD and a post-bronchodilator FEV1 ≥50 and ≤70% of the predicted value, a post-bronchodilator FEV1/forced vital capacity ≤0.70, and ≥2 on the modified Medical Research Council dyspnea scale. Patients had a history of CVD (coronary artery disease, peripheral arterial disease, prior stroke or myocardial infarction, or diabetes mellitus with target organ disease) or increased cardiovascular risk (≥60 years and receiving medications for ≥2 of the following: hypercholesterolemia, hypertension, diabetes mellitus, or peripheral vascular disease). ICS and LABA treatments were discontinued before study entry. Participants were then randomized to receive one of the following (once daily): placebo fluticasone furoate (FF) 100μg vilanterol (VI) 25µg FF/VI 100/25μg. Adverse events (AEs) were collected at each study visit by the study investigators and coded using the Medical Dictionary for Regulatory Activities (MedDRA® version 18.0; International Federation of Pharmaceutical Manufacturers and Associations, Geneva, Switzerland). Reported pneumonia-related events were not increased in the ICS-containing arms (FF and FF/VI) compared with placebo. There was no difference in the time to first on-treatment pneumonia AE in ICS-containing arms compared with placebo. These data suggest that the pneumonia risk with ICS use may be of less concern in patients with COPD with moderate airflow limitation than previously thought.

This study was funded by GSK (HZC113782/NCT01313676). Editorial support was provided by Emma McConnell, PhD ((in the form of assembling the first draft of the poster under the direction of the authors) and Rebecca Seth (in the form of redrawing figures and formatting the poster) at Gardiner-Caldwell Communications (Macclesfield) and was funded by GSK. Patients with chronic obstructive pulmonary disease (COPD) are at increased risk for pneumonia. Previous studies have shown that pneumonia risk in COPD is partly related to the severity of airflow limitation. For patients receiving inhaled corticosteroid (ICS)-containing regimens, the risk of pneumonia is increased in those with severe (forced expiratory volume in 1 second [FEV1] ≥30% and <50% predicted) and very severe (FEV1 <30% predicted) airflow obstruction. The Study to Understand Mortality and MorbidITy in COPD (SUMMIT) investigated the effects of an ICS, a long-acting β-agonist (LABA), and the combination in patients with moderate COPD who had, or were at high risk for, cardiovascular disease (CVD). The risk of pneumonia in patients with COPD receiving an ICS, a LABA, or the combination was assessed as a safety endpoint in SUMMIT. Participants 16,568 patients underwent randomization and took study medication to be included in the safety population. Baseline characteristics were balanced across all treatment arms (Table 2). Pneumonias Total exposure to study medication was higher in the FF/VI treatment group compared with FF and VI treatment groups, and placebo. The incidence and rates of pneumonia AEs and pneumonia serious AEs (SAEs) were comparable in the FF-containing groups and placebo (Table 3). On-treatment and post-treatment fatal pneumonia SAEs occurred in <1% of patients in all treatment groups (Table 3). Treatment did not increase the rate of adjudicated on-treatment deaths compared with placebo (Table 3). Table 2.

Combination products are included in all applicable respiratory medication classes. Time to pneumonia AEs There was no difference in the time to first on-treatment AE or SAE in the FF-containing treatment groups compared with placebo (Figure 1). Treatment effect on the risk of pneumonia was assessed by comparing the incidence, rate, and Kaplan Meier curves for pneumonia. Adverse events of special interest (AESIs) were those associated with the known pharmacologic action of ICS or LABA therapy. For pneumonia, this used a pre-defined list of preferred terms from MedDRA that allowed a comprehensive review of pneumonia data (Table 1). Rate represents the number of events per 100 subject-years of exposure, calculated as: (total number of AEs*100)/total duration of exposure in years.
