NCT05033990
This is an observational study of 1000 participants to further define the nature of early chronic obstructive pulmonary disease (COPD) in younger, at-risk individuals. The study has three main goals: * To use CT scan imaging to identify which smokers will develop COPD. * To identify biomarkers predictive of smokers that will develop COPD. * To determine if sputum (phlegm) can be analyzed to predict which smokers will develop COPD. Procedures (methods): All participants will undergo study related questionnaires assessing medical history, smoke exposure and use, medication use, social and behavioral health, pulmonary symptoms, food frequency, and will provide nasal swab, blood, stool, and urine samples, pulmonary function testing to determine function, sputum induction to provide a sputum sample for airway biospecimen analysis, and CT imaging of the lungs.
NCT04456673
Primary Objective: To evaluate the efficacy of dupilumab administered every 2 weeks in patients with moderate or severe Chronic Obstructive Pulmonary Disease (COPD) as measured by * Annualized rate of acute moderate or severe COPD exacerbation (AECOPD) Secondary Objectives: To evaluate the effect of dupilumab administered every 2 weeks on * Pre-bronchodilator forced expiratory volume in 1 second (FEV1) over 12 weeks compared to placebo * Health related quality of life, assessed by the change from baseline to Week 52 in the St. George's Respiratory Questionnaire (SGRQ) * Pre-bronchodilator FEV1 over 52 weeks compared to placebo * Lung function assessments * Moderate and severe COPD exacerbations * To evaluate safety and tolerability * To evaluate dupilumab systemic exposure and incidence of antidrug antibodies (ADA)
