The study is a 44 weeks, prospective, randomized, placebo-controlled, double-blinded, parallel group two-center trial. Forty patients are recruited among the outpatients of the chronic obstructive pulmonary disease (COPD) clinic, Hospital of South West Jutland and Lilleblt Hospital according to the inclusion and exclusion criteria. The patients are randomized to receive liraglutide 3 mg per day (initial dose 0.6 mg, increasing by 0.6 mg weekly until 3 mg is reached) or placebo. At baseline, after four weeks (assessment of the acute effect of liraglutide), 20 weeks, and 40 weeks (assessment of the combined effect of liraglutide and weight loss) and at week 44 (assessment of the weight-loss after discontinuation of liraglutide) the patients are assessed by physical examination, carbon monoxide (CO) diffusion test, pulmonary function test, biomarkers of inflammation (CRP, interleucine-6 (IL-6), monocyte chemitactic protein-1 (MCP-1)), Fluorodeoxyglucose (FDG)/PET-CT scan of the lungs, 6-minute walking test, respiratory polygraphy and validated questionnaires including basic dyspnea index, transition dyspnea index, COPD Assessment Test (CAT)-score, short-form-36 (SF-36) and Epworth Sleepiness Score.
COPD is a common disease characterized by pulmonary inflammation, reduced pulmonary capacity, reduced physical activity and quality of life. Obesity is likewise a common disease characterized by inflammation, reduced physical activity and quality of life. Targeting both obesity and inflammation may turn out beneficial for patients with COPD and obesity, and this study explore the possibility to reverse a vicious cycle of COPD, lack of physical activity and obesity. The primary objective of the study is to evaluate the effect of Liraglutide 3mg in patients with COPD on patient reported outcomes as measured by the Transition Dyspnea Index. The hypothesis is that Liraglutide 3mg exerts beneficial effects on measures of pulmonary function and quality of life in overweight patients with COPD by reducing body weight and reducing inflammatory activity.
