Multiple dose safety and pharmacokinetics in healthy male subjects
Patients with Chronic obstructive pulmonary disease (COPD) tend to have cough, excess mucus production and breathlessness as cardinal features. The excess mucus production often leads to frequent infections, exacerbations and poor quality of life. Mucociliary clearance may have an impact on improving symptoms, exercise tolerance, quality of life and reduce exacerbations. High frequency chest wall oscillation(HFCWO) devices use percussion to the chest wall delivered from a pump through a close fitting inflatable vest. This technique has been shown to enhance mucus clearance in patients with cystic fibrosis and Bronchiectasis. This pilot study was designed to explore the feasibility, tolerance and effectiveness of the HFCWO in patients with advanced COPD.
Study purpose is to evaluate if subjects with chronic obstructive pulmonary disease (COPD) are more likely to be responsive to additional inhaled corticosteroids if they have a positive response to hyperosmolar challenge with mannitol than if their response is negative.
This study was intended to assess how well inhaled NVA237 opens up the airways of patients with mild, moderate or severe COPD over a 24 hour period after a 14 day treatment period.
To test the compliance, tolerance, safety and to get preliminary insights into the efficacy of a new oral nutritional supplement (containing n-3 fatty acids, amino acids and antioxidants) designed to prevent or delay cachexia and anorexia in patients with chronic heart failure (CHF) or chronic obstructive pulmonary disease (COPD).
This study is an observational prospective pilot trial that utilizes finger cuff non invasive hemodynamic monitoring (NexfinHD Monitor) to assess 4 different groups (CHF/COPD, Trauma, Sepsis, Stroke) of patients on arrival to the Emergency Department and to document the changes seen in these hemodynamics with acute therapies.
Asthma and chronic obstructive pulmonary disease (COPD) are chronic inflammatory airway diseases affecting millions of people worldwide. Inhaled corticosteroids (ICS) are by far the most effective treatment with a broad anti-inflammatory spectrum. Nevertheless, most COPD patients and a proportion of severe asthma patients are corticosteroid-resistant (CR) and to fail to respond to ICS even when higher doses are given. These corticosteroid-resistant patients suffer from persistent symptoms and repeated asthma exacerbations. It has been suggested that smoking and oxidative stress may induce corticosteroid-resistance. The reactive oxygen species (ROS) responsible for oxidative stress can be generated exogenously (air pollutants, cigarette smoke) and endogenously by metabolic reactions. After inhaling air pollutants or cigarette smoke, the bronchial epithelium is exposed. Preliminary data from our own lab suggest that smoking and oxidative stress may decrease epithelial cell-cell contact formation. This results not only in a decreased barrier function, but also in an increased production of pro-inflammatory mediators.
Smoking induces an inflammatory reaction in the airways which can ultimately result in persistent damage and the development of a Chronic Obstructive Pulmonary Disease (COPD). However, not all subjects who smoke end up with COPD. After long-term smoking, approximately 20% of subjects develop COPD. At this time, it is unclear why some subjects develop COPD, whereas others maintain a normal lung function. In addition, smoking has important consequences in asthma. Patients with asthma who smoke have a more severe asthma and more often experience an asthma exacerbation. In addition, it has been shown that inhaled corticosteroids are less effective in smoking asthmatics. With this research project, the researchers will investigate the effects of smoking on the airways. To this end, the researchers will compare markers of airway inflammation, lung function and symptoms between healthy smokers and non-smokers of varying age. In addition, the researchers will compare those healthy subjects with patients with asthma and COPD which are characterized in earlier studies.
This study assessed the efficacy and safety of indacaterol (150 µg once daily [od]) when combined with tiotropium (18 µg od) versus tiotropium (18 µg od) treatment alone in patients with chronic obstructive pulmonary disease (COPD)
