Active clinical trials for "Pulmonary Disease, Chronic Obstructive"

The purpose of this study is to determine steady-state efficacy and dose response profile and to assess safety and pharmacokinetic profile of nebulized EP-101(SUN101) after 7-day dosing using an investigational high efficiency nebulizer (eFlow®) compared with placebo and two active comparators in patients with moderate to severe Chronic Obstructive Pulmonary Disease (COPD).

Pulmonary rehabilitation is an effective treatment for people with chronic obstructive pulmonary disease (COPD) which improves symptoms, reduces hospitalisation and lowers healthcare costs. However less than 1% of Australians with COPD receive pulmonary rehabilitation each year, due to poor access to programs and high levels of disability. This randomised controlled trial will examine the benefits and costs of a novel, entirely home-based pulmonary rehabilitation program for COPD. We hypothesise that home-based pulmonary rehabilitation can deliver equivalent clinical outcomes at lower cost than the centre-based program. We will randomly allocate 144 people with COPD to undertake either standard pulmonary rehabilitation in a hospital setting, or a low-cost home-based program. Those who undertake pulmonary rehabilitation in the hospital setting will attend the hospital twice each week for eight weeks for supervised exercise training and education. People in the home pulmonary rehabilitation group will receive one home visit and weekly telephone calls for eight weeks, for supervision and mentoring of exercise and provision of education. We will compare the number of people who complete the program in each setting. We will also test whether the groups have similar results for the standard pulmonary rehabilitation outcomes of breathlessness, quality of life and exercise capacity, at the end of the program and 12 months later. We will compare health care costs and personal costs between groups after 12 months. If home-based pulmonary rehabilitation can improve uptake of this important treatment, deliver good clinical outcomes and reduce costs this will have significant and long-lasting benefits for patients, the community and the health system

Noninvasive ventilation (NIV) is a form of ventilation delivered by a mask and is an important mode of treatment in patients with both acute and chronic respiratory (breathing) failure. Humidification is widely accepted as an essential part of the ventilation strategy in patients receiving invasive ventilation (i.e. via a tube inserted into the mouth), but its role during NIV use is not proven. Consequently, there is a variation in practice with regard to humidification during NIV. Humidification is important in maintaining upper and lower airway mucosal function and patients requiring NIV often report symptoms, such as throat dryness, due to a lack of airway humidity. Success of NIV in the acute setting is dependent on many factors including, patient tolerance of NIV during the acute phase. In patients with chronic obstructive airways disease (COPD), poor tolerance results in NIV failure, which necessitates endotracheal intubation or treatment failure. Furthermore, invasive ventilation increases the risk of a hospital acquired pneumonia, which is associated with a worse outcome. In the long term setting of NIV use, again patients frequently report symptoms due to drying of the airways and adherence to NIV can be highly variable. Adherence in these patients is important in improving both quality and length of life. Humidification devices may be technically effective, but clinicians have concerns regarding potential negative effects of these devices. There is a requirement to evaluate the use of humidification in both the acute and long term use of NIV, particular, in terms of patient ventilator interaction, which will impact on comfort and adherence to NIV. This will effect the overall effectiveness of ventilation. The investigators propose a randomised controlled trial to investigate the effects of a humidification system during noninvasive ventilation.

Pilot study in 15 stable male subjects with severe-to-very severe Chronic Obstructive Pulmonary Disease (COPD) to evaluate the effects of short term use of the Breathe Technologies noninvasive open ventilation (NIOV) system on respiratory mechanics during constant work rate exercise in subjects with severe COPD.

To study in clinically stable Chronic Obstructive Pulmonary Disease (COPD) patients with muscle atrophy: The short-term effects of 4 months exercise training including nutritional supplementation versus exercise training alone on physical functioning (skeletal muscle strength and exercise capacity) and body composition. The long-term effects of 4 months of exercise training and nutritional supplementation followed by 8 months of nutritional counseling (with supplementation on advice) and feedback on physical activity level versus 4 months of exercise training and 8 months with feedback on physical activity level alone on physical functioning, body composition and cardiometabolic risk profile; The cost-effectiveness of exercise rehabilitation and nutritional intervention versus exercise rehabilitation alone.

This study was designed to test the following hypothesis: A) The acute and long-term (3 weeks) bronchodilator-induced changes in exercise tolerance and in the physiological response during the endurance shuttle walk will be greater with tiotropium compared to placebo in COPD patients. B) Three weeks of bronchodilation will be associated with increase activity of daily living as evaluated using the London Chest Activity Daily Living scale.

This study assessed the effect of once-daily indacaterol and glycopyrronium bromide (QVA149) on exercise endurance in patients with moderate to severe Chronic Obstructive Pulmonary Disease (COPD).

The overall objective of this study is to assess the efficacy and safety of 52 weeks once daily treatment with orally inhaled tiotropium + olodaterol FDC (delivered by the RESPIMAT Inhaler) compared with the individual components ( tiotropium, olodaterol) (delivered by the RESPIMAT Inhaler) in patients with Chronic Obstructive Pulmonary Disease (COPD).

Beta-endorphins, which are naturally occurring narcotic substances, have been shown to alter the perception of breathlessness. Oral ketoconazole, an antifungal antibiotic, increases blood levels of beta-endorphins. The study hypothesis is that oral ketoconazole will reduce ratings of breathlessness induced by resistive breathing loads.

The purpose of this study is to investigate heart rate lowering efficacy and respiratory safety of ivabradine in patients with asthma and COPD.
