NCT01969344
SPIROMICS I, SPIROMICS II, and SPIROMICS III are longitudinal observational studies of Chronic Obstructive Pulmonary Disease (COPD) cohort. SPIROMICS I had two primary aims: (1) To find groups of patients with COPD who share certain characteristics; (2) To find new ways of measuring whether or not COPD is getting worse and to provide new ways of testing whether a new treatment is working. SPIROMICS II had three primary aims: (1) To define the natural history of "smokers with symptoms despite preserved spirometry" and characterize the airway mucus abnormalities underlying this condition; (2) To determine the radiographic precursor lesion(s) for emphysema and identify the molecular phenotypes underlying airway disease and emphysema; (3) To advance understanding of the biology of COPD exacerbations through analysis of predisposing baseline phenotypes, exacerbation triggers and host inflammatory response. SPIROMICS III has three primary aims: (1) To identify the main forms of smoking-related airway disease that are caused by pathological airway mucus, their biological underpinnings, and their physiological significance; (2) To identify longitudinal trajectories in established and novel CT measures of emphysema, test how they predict COPD progression, and define their underlying biology; (3) To identify environmental and social determinants of health that impact disease severity and progression and their influence on lung structure, biology, and health disparities in COPD.
NCT00870857
Despite the availability of highly active antiretroviral therapy (HAART), lung diseases remain a leading cause of morbidity and mortality in those with HIV infection. There have been no large-scale studies detailing pulmonary complications in the HAART era. Substantial gaps exist in our knowledge of the spectrum and pathogenesis of pulmonary disorders in this population, particularly in women and minorities whose numbers with HIV or AIDS have increased. The Multicenter AIDS Cohort Study (MACS) and the Women's Interagency Health Study (WIHS) are prospective, multi-center cohorts that follow approximately 5000 HIV+ subjects and HIV- controls. Although pulmonary disease has not been an area of focus, these established cohorts provide a unique opportunity to systematically study pulmonary complications of HIV infection. Emphysema is of particular interest in the current HIV era because it is likely to increase as this population lives longer with chronic HIV. HIV-infected persons have an increased incidence of emphysema compared to those without HIV infection, and it has been hypothesized that this accelerated disease progression is the result of one or more latent infectious agents that amplify the pulmonary inflammation. Accelerated emphysema was described in HIV infection in a predominantly male population before HAART. The current prevalence and characteristics of HIV-associated emphysema, and the potential impact of gender, have not been rigorously defined.
NCT04053634
Phase 3 study to evaluate the efficacy and safety of a benralizumab in patients with moderate to very severe COPD with a history of frequent COPD exacerbations and elevated peripheral blood eosinophils (≥300/μL). Eligible patients must have a history of ≥2 moderate and/or severe COPD exacerbations in the previous year despite receiving triple (ICS/LABA/LAMA) background therapy for at least 3 months and ICS-based dual inhaled treatment for the remainder of the year. Eligible patients must also have an elevated blood eosinophil count. The treatment period will be of variable duration and will continue until the last patient has the opportunity to complete a minimum of 56 weeks, at which point all patients will complete the study. The primary endpoint will be analyzed at Week 56.
NCT04315558
RARICO is a pragmatic, randomized, controlled, double-blinded, multi-center trial evaluating the safety and feasibility of nebulized revefenacin in comparison to nebulized ipratropium in patients with COPD and acute respiratory failure requiring invasive mechanical ventilation.
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.
NCT05326412
This study is an exploratory, two-part, 12-week, Phase 2a study to evaluate the mechanism of action of Itepekimab (anti-IL-33-mAb) and its impact on airway inflammation in former and current smokers with COPD, aged 40 to 70 years. This study consists of participants who have been on a standard-of-care (SoC) mono (long-acting β2-agonist \[LABA\]) or long-acting muscarinic antagonist \[LAMA\]), double (inhaled corticosteroid \[ICS\] + LABA, LABA + LAMA or ICS + LAMA), or triple (ICS + LABA + LAMA) controller therapy for COPD for at least 3 months prior to Screening (Visit 1) with stable dose and regimen for controller therapy for ≥1 month prior to Screening (Visit 1) and during the screening period. Participants will stay on their established controller medications for COPD throughout the duration of the study, with the exception of systemic corticosteroids and/or antibiotics used for acute exacerbation of COPD (AECOPD). Part A will consist of participants who are former smokers with COPD; Part B will consist of participants who are current smokers with COPD. The total study duration for each part (Part A and Part B) is approximately 36 weeks: * 4-week screening period * 12-week treatment period * 20-week followup period

NCT06891755
The objective of this study is to assess the safety and efficacy of Apreo BREATHE system when used to support native airways and release trapped air in the treatment of adult COPD patients with emphysema suffering from dyspnea due to hyperinflation despite optimal medical treatment. The Apreo BREATHE Airway Scaffold is a permanent implant designed to tent open native airways. The study will include up to 250 participants at up to 25 study centers located in the United States and Europe. Study subjects will be followed for 3 years. The main questions it aims to answer are: Is it safe? Does it work?
NCT01558817
Outcomes after in-hospital cardiopulmonary resuscitation (CPR) are very poor, particularly in patients with oxygen dependent chronic obstructive pulmonary disease (COPD) or metastatic cancer. Recent work found that in-hospital CPR is being performed more often before death with unchanging survival and that fewer CPR survivors are being discharged home, thus suggesting that CPR is increasingly performed without benefit and that the burden of this ineffective treatment is increasing. Unlike other medical procedures, CPR has become the default provided to all patients even those with tremendously poor outcomes. It is time to change the paradigm of CPR. Through comparing an innovative "informed assent" approach toward in-hospital CPR (informing patients that their underlying chronic illness makes outcomes of CPR so poor that CPR is not performed while allowing them to disagree) versus usual care in a group of chronically ill patients with reduced life expectancy, the investigators aspire to demonstrate that CPR delivery can be reduced. And in addition that DNR status increases, while preserving patient quality of life and decreasing the burden of this ineffective treatment to both patients and families. If effective, this informed assent intervention has the potential to revolutionize how the investigators discuss CPR with the investigators chronically ill patients.
NCT02984124
This multicenter RCT of 200 hospitalized patients and their family members evaluates an "informed assent" approach to discussing cardiopulmonary resuscitation, compared to usual care, in older seriously ill hospitalized patients with severe life-limiting illness or severe functional impairment.
