The pharmacokinetics of cavosonstat 7. Assessment of quality of life
The study will evaluate bioavailability, pharmacokinetics, safety, and tolerability of budesonide, glycopyrronium and formoterol (BGF) metered dose inhaler (MDI) formulated with 3 different propellants: Propellant 1 (Treatment A [test]), Propellant 2 (Treatment B [test]) and Hydrofluoroalkane (HFA) (Treatment C [reference]).
This non-interventional study aims to collect information on the patient's quality of life, as well as the quality of sleep when stepping up to a fixed triple maintenance therapy (Trimbow®) as per physicians' decision, independent from study participation, and to assess its effectiveness in daily life, in general practitioner setting.
The 1-minute sit to stand (1-min STS) test is a standardized test which is used to examine exercise capacity in patients with chronic obstructive pulmonary disease (COPD). The chair seat height used is standardized to 46-48 cm. Using a standard seat height for all patients - irrespective of their body height - may lead to invalid estimates of functional exercise capacity. The objective of this study is to assess whether there is a difference in repetitions during the 1-min STS test if the seat height is adjusted to 90° knee joint angle or the standard height chair of 46 cm is used.
Blood eosinophils are a type of white blood cell that helps fight infection. They have a number of different functions but are primarily involved in numerous inflammatory processes. They are recruited from the blood into sites of inflammation. In patients with COPD, higher blood eosinophil count (BEC) predicts a greater reduction in moderate and severe exacerbations in response to inhaled corticosteroid (ICS) therapy. The Global Initiative for Chronic Obstructive Lung Disease strategy (GOLD 2019) recommends the use of BEC to guide ICS therapy and states that eosinophil levels above 300 cells/μL can help identify responders, guiding initial dual therapy, with "little or no effect at a BEC < 100 cells/μL". The National Institute for Health and Care Excellence (NICE) COPD 2018 guideline states that a higher BEC is associated with ICS response, but does not specify a threshold. Earlier research studies have suggested that at lower levels of BEC the harm of ICS due to pneumonia is greater than the benefit of severe exacerbation reduction. Patients with COPD can have "flare ups" of their disease known as exacerbations. Blood eosinophils play a critical role in assessing severity of these exacerbations and guiding management. The association between BEC and reduction in exacerbation frequency is based on BEC measured when the patient is clinically stable. Transient low eosinophil count (eosinopenia with BEC < 50 cells/μL) during severe exacerbation is extremely common. In the Dyspnoea, Eosinopenia, Consolidation, Acidaemia and atrial Fibrillation (DECAF) score derivation and validation studies combined, eosinopenia was present on admission in 1,340 of 2,645 severe exacerbations of COPD (ECOPD) and is associated with longer length of stay, higher in-hospital and one year mortality. Although eosinophilic COPD exacerbations occur, overall BEC during moderate or severe exacerbation is lower than stable state. In ECOPD managed in critical care low BEC is associated with higher rate of septic shock and mortality. BEC are also suppressed during other acute illnesses, notably sepsis. Failure to recognise that BEC are often suppressed during acute illness compared to stable state may lead to ICS therapy being inappropriately withheld. The effect of exacerbation and other acute illnesses on eosinophils is under-appreciated. Both NICE and GOLD guidelines fail to mention whether BEC should be prospectively measured when patients are stable (reflecting RCT evidence), or if reliance on historical values is acceptable. In routine practice some clinicians rely on previous BECs to avoid a delay in treatment decisions. A number of these historical counts will have been taken during illness, underestimating the patients' stable-state BEC. Conversely, COPD is associated with other medical conditions, and BEC may be requested for reasons other than acute illness. Using the highest BEC from multiple measures in the previous 24 months may therefore better agree with stable state counts. The primary aim of this trial is to assess the reliability of using BEC over the preceding 24 months to assess COPD eosinophil phenotype at both GOLD thresholds. The primary outcome will be based on using the highest of at least three BEC. Secondary outcomes include a) the level of agreement between baseline stable state BEC and both mean and the highest BEC over the preceding 24 months, b) the influence of the number of BEC measures available and c) the effect of limiting the time frame from 24 months to the previous 12 months. BEC is associated with disease severity, providing further evidence that COPD eosinophil phenotype may change over time. As an exploratory analysis, periods of sustained change in eosinophil phenotype will be sought, and the relationship between eosinophil phenotype and patient characteristics and certain medication will be assessed. The investigators will also assess the relations between the dependent variables stable state absolute eosinophil and basophil counts and both eosinophil to basophil and neutrophil to lymphocyte ratios and the following clinical outcomes: a) moderate and severe exacerbations and b) mortality. Some of these variables have previously been shown to be related to disease severity and mortality.
Chronic obstructive pulmonary disease (COPD) is a public health problem: high prevalence; increasing morbidity and mortality; impact on health costs. Pulmonary rehabilitation (PR) is a multidisciplinary intervention combining exercise training, therapeutic education, psychosocial and behavioral interventions. Its effects are beneficial in the short and medium terms but are limited in time, between 6 and 12 months, for patients who do not pursue regular physical activity (PA) in post-rehabilitation and who do not adopt behavioral changes for health, by loss of motivation. Maintaining the long-term benefits acquired during a short-term PR program is therefore a major issue in the management of COPD. The recent development of remote rehabilitation is a promising approach that has been studied in few studies. In a randomized, controlled and multicenter study, we propose to test the hypothesis that the use of a mobile telerehabilitation solution will allow COPD patients to mainain at long-term the benefits acquired during a short-temr programm and therfore improve their quality of life.

The purpose of this study is to determine if ensifentrine is safe and effective for the treatment of patients with moderate to severe Chronic Obstructive Pulmonary Disease (COPD).
The objective of the study is to evaluate the effects of a mobile self-management app in clinical practice for recently discharged COPD patients on application use, self-management, anxiety and depression, expectations and experiences, patients' and health care professionals' satisfaction and hospital readmissions.
This study has two parts. The main purpose of Part 1 of this study will be to examine how safe and effective two doses of SelK2 is on participants with mild asthma. Lung function and inflammatory cell numbers will be measured in response to the administration of an allergen (a compound to which the participant is allergic) into the lungs in the presence or absence of SelK2. Part 2 of this study will examine how safe and effective one dose of SelK2 is on participants with chronic obstructive pulmonary disease (COPD). Lung function and inflammatory cell numbers will be measured in COPD patients in the presence or absence of SelK2. SelK2 may block the movement of key inflammatory cells into the lungs and consequently improve lung function in these two patient populations.
This is a double-blind randomized controlled trial evaluating the effect of perioperative dual bronchodilator therapy on post-operative pulmonary function and health-related quality of life (QoL) in mild-to-moderate less symptomatic COPD patients undergoing lung cancer surgery. Investigators hypothesized that dual bronchodilator, as compared with placebo, would prevent reduction of pulmonary function after surgical resection and improve postoperative health related QoL.
