Active clinical trials for "Lung Diseases, Obstructive"

Phase I study to evaluate the safety and tolerability of single ascending intravenous doses of MEDI2338 in subjects with stable, mild to moderate chronic obstructive pulmonary disease (COPD).

The purpose of this study is to compare the efficacy and safety/tolerability of indacaterol and glycopyrronium (QVA149) (fixed-dose combination) with fluticasone/salmeterol over a 26-week period in patients with moderate to severe COPD.

Chronic obstructive pulmonary disease (COPD) is one of the commonest respiratory diseases. During the early stage of COPD, patients only have mild respiratory symptoms or signs which may lead to under-diagnosis of the disease. Patients may show poor response to treatment at later stages of the disease, associated with higher mortality and incidence of re-hospitalization and disability causing burden for both the families and the society. So far, there is no large-scale clinical trial on long-term intervention with tiotropium bromide (Spiriva) in patients with early stages of COPD (i.e. GOLD Stage I-II COPD or asymptomatic COPD). It would be of great significance for COPD prevention and treatment if the investigators could prove that tiotropium decreases the lung function decline and reverses disease progression in patients with early-stage COPD. The investigators objective is to evaluate the efficacy of long-term intervention with tiotropium in early stage (FEV1 ≥50% predicted) COPD (difference of trough FEV1, number of exacerbations, time to first exacerbation, quality of life, etc) and relevant pharmacoeconomic endpoints.

The aim of the present study is to evaluate the 24h bronchodilatory efficacy of inhaled aclidinium bromide 400 µg administered twice a day versus placebo and tiotropium bromide, respectively, after 6 weeks of treatment.

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.

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).
