Filter by:The purpose of this study is to investigate the dose response of RPL554 in patients with moderate to severe CHRONIC OBSTRUCTIVE PULMONARY DISEASE that are still symptomatic despite treatment with a stable background of tiotropium over 4 weeks of treatment. This study is intended to support optimal dose selection for a Phase III program evaluating RPL554 as an add-on treatment to standard of care therapy.
This purpose of this study is to determine whether nasal delivery of heated and humidified air for a period of 4 hours will improve the clearance of mucus from the lungs of patients with chronic obstructive pulmonary disease (COPD). Mucus clearance will be measured using a nuclear medicine imaging procedure called a mucociliary clearance scan. Humidified air (with added oxygen if needed) will be delivered from the Fisher and Paykel myAirvo2 heater/humidifier through an Optiflow nasal cannula.
In COPD patients with chronic hypercapnic respiratory failure, the prognosis is poor and the treatment with non invasive ventilation is actually well established. However the best mode of ventilation is not well known. In severe COPD patients various disorders of respiratory mechanics result in insufficient ventilation, which can be life-threatening or create NIV discomfort. The main characteristic of these disorders is a cyclical closing of small airways that can limit an expiratory flow and provoked some fluctuations in flow curve. To our knowledge, the management of dynamic hyperinflation seems to play an important role in explaining the effect of the NIV. Few studies have examined the effects of the machine's adjustments on dynamic hyperinflation. The main objective of this study is to analyze the impact of specific ventilatory modes supposed to reduce the dynamic hyperinflation on the hematosis, by studying transcutaneous pressure of carbon dioxide, in severe hypercapnic COPD patients ventilated by NIV. Two modes of ventilation will be compared. First one is an algorithmic mode developed by the company Löwenstein (AirTrap Control, Trigger Lockout and the Expiratory Pressure Ramp). The second one is a standard algorithmic mode, used in the same ventilator. These two ventilatory modes will be evaluated in each patient, during two consecutive nights in current living conditions at home.
Jet nebulizers have been the standard delivery system for aerosolized medications commonly prescribed to Chronic Obstructive Pulmonary Disease (COPD) patients; however, these devices are inefficient and require an external pressurized gas source to operate. Vibrating mesh nebulizers have a significantly higher efficiency of delivering drugs to the lung compared to conventional jet or ultrasonic nebulizers because of the high fine particle fraction created by the rapid vibration. This post-market study will investigate the potential benefits of a vibrating mesh nebulizer compared a standard jet nebulizer. The study will include stable, ambulatory COPD patients who are currently using a jet nebulizer system. Participants will be asked to use each device for a period of 30 days. Patient preference and changes to quality of life will be evaluated.
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 and 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 anti-drug antibodies (ADA)
To test if high-flow conditioned oxygen therapy is noninferior to NIV for preventing postextubation respiratory failure and reintubation in patients with hypercapnic COPD, investigators plan to conduct the participants level, 1:1 randomized trial at the respiratory ICU. Participants were randomized to undergo either high-flow conditioned oxygen therapy or noninvasive mechanical ventilation after extubation. Primary outcomes were reintubation and postextubation respiratory failure within 72 hours. Secondary outcomes included length of RICU stay after extubation and mortality; partial pressure of arterial carbon dioxide.
The goal of this study is to assess the impact of pharmacist-led benefits investigations and application of clinical practice guidelines on patient access to inhalers and time to hospital readmission or Emergency Department (ED) visit.
Cross-over trial of the effect of a salt particle inhaler on pulmonary muco-ciliary cleansing in COPD patients as measured by lung scintigraphy.
This study investigates cytokine Messenger (mRNA) and microRNA (miRNA) level expression of interleukin (IL) -6, IL-8, IL-17, tumor necrosis factor (TNF)-alpha, monocyte chemoattractant protein (MCP)-1, macrophage inflammatory protein (MIP)-1 beta and transforming growth factor (TGF)-beta regarding their reproducibility and responsivity in induced sputum and nasal mucosa of patients with chronic obstructive pulmonary disease (COPD) in order to assess their potential as a biomarker outcome measure.
Chronic obstructive pulmonary disease is a serious disease . Exacerbations of Chronic obstructive pulmonary disease is an acute worsening condition of Chronic obstructive pulmonary disease, which always accompanied by clinical symptoms such as, shortness of breath and increased production of sputum. Respiratory infection (bacteria or viruses or mixed) is thought to be the main cause in most exacerbations.
