Active clinical trials for "Pulmonary Disease, Chronic Obstructive"

Chronic Obstructive Pulmonary disease (COPD) patients with chronic hypercapnic respiratory failure are more likely to develop exacerbations. Non-invasive ventilation has been proposed to treat acute respiratory failure but little information is available about the benefits of home non-invasive ventilation in COPD patients with chronic hypercapnic respiratory failure surviving an acute hypercapnic respiratory failure. The purpose of this study is to determine whether home non-invasive ventilation can reduce recurrent acute hypercapnic respiratory failure in COPD patients who survived an episode of acute hypoxemic respiratory failure (AHRF) treated by Non-invasive ventilation (NIV).

The study will assess the Pharmacokinetic (PK) and safety of BGF MDI [Budesonide/glycopyrronium/formoterol (BGF) metered dose inhaler (MDI)] formulated with 2 different propellants :Hydrofluoroolefin (HFO) and Hydrofluoroalkane (HFA) with oral activated charcoal in healthy subjects (male or female).

This prospective, observational study is designed to investigate clinical outcomes and collect patient feedback on the use of Wellinks, an integrated virtual chronic obstructive pulmonary disease (COPD) management solution, for patients recently discharged from the hospital due to an acute exacerbation of their COPD.

Research Background Chronic obstructive pulmonary disease (COPD) is a progressive chronic lung disease that makes breathing difficult with mucus build-up in the inflamed airway and lungs hyperinflation due to expiratory flow limitation. Global Initiative for Chronic Obstructive Lung Disease (GOLD) defines COPD as a common, preventable and treatable disease with significant morbidity and mortality, and incurs intensive expenditure of healthcare resources. This disease is currently the fourth leading cause of death in the world but is projected to be the 3rd leading cause of death by 2020. In 2012, global death from COPD accounted about 6% which equal to more than 3 million deaths in world population. The mortality burden of COPD is expected to rise to 8.6% by 2030. In Malaysia, the prevalence of moderate to severe COPD in Malaysia in 2010 is 4.7% which equals to 448,000 cases. COPD is attributed by long-term exposure to noxious particles and toxic gases. Tobacco smoking is the main cause of COPD globally. The Third National Health and Morbidity Survey (NHMS III) conducted in Malaysia in 2006 showed that the prevalence of male ever smokers was 57.6% and in female is 2.5%. Other than that, inhalation of organic or chemical dust and fumes, and biomass exposure also among the risk factors of COPD. Exposure to noxious particles will cause activation of inflammatory immune responses. However, continuous and repetitive exposure towards these noxious particles will lead to tissue remodelling in small airways causing smooth muscle hypertrophy and fibrosis causing major site of obstruction in COPD. In COPD patients, the small airways represent the key sites of airflow obstruction, and small airway disease (SAD) is considered a functional hallmark of disease. The presence of SAD progressively increases with higher GOLD classifications and it is closely related to the high impact of disease measured by COPD Assessment Test (CAT) questionnaire. Distributions of SAD among COPD patients classified according to GOLD classification. In each of GOLD A, B, C and D class, the prevalence of SAD are 49%, 88%, 61%, and 96% respectively. As presence of SAD is closely related to high impact of disease with CAT score ≥10 , they tend to have more symptoms.

Chronic obstructive pulmonary disease (COPD) patients with mucus hyper secretion tend to demonstrate increased frequency of infective exacerbations and a steeper slope of decline in lung function. Enhanced mucosal clearance with high frequency chest wall oscillation (HFCWO) devices previously used in cystic fibrosis and bronchiectasis patients may offer the opportunity for community based, self-managed therapy to improve quality of life and lung function. The aim of this study is to compare effects of active cycle of breathing and high frequency chest wall oscillations in chronic obstructive pulmonary disease .This study will be a Randomized Clinical trial and will be conducted at Physical Therapy Department of DHQ Hospital NAROWAL. The study will be completed within the time duration of six months. Consecutive sampling technique will be used to collect the data. A sample size of Total 42 patients will be taken in this study. Patients will be divided into two groups. BODE Index will be used as outcome measurement tool. Group A will receive the Active cycle of breathing technique and it will performed twice a day for 4 week intervention period for 20 minutes. Group B will receive high frequency chest wall oscillations at 13-15Hz oscillating frequency for 20 minutes twice a day for 4 weeks. The collected data will be analyzed on SPSS - 25.

This mechanistic study is a single-center, randomized, double-blind, placebo-controlled, cross-over study to evaluate the effect of dual bronchodilation with QVA149 on cardiac and lung function parameters in hyperinflated COPD patients.

To evaluate the efficacy, safety and tolerability of multiple doses of QBW251 vs placebo administered orally, on airway function, lung volume, and quality of life in patients with chronic obstructive pulmonary disease (COPD)

This is a Phase I open-label, single center study to assess the PK and safety of BGF MDI 320/14.4/9.6 µg in subjects with moderate to severe COPD. Pharmacokinetics will be assessed following a single dose administration on the first treatment day (Day 1) and will be assessed again after 7 days of repeat dosing. This study includes a Screening Period of up to 28 days and a single Treatment Period of 8 days. A follow-up phone call will be conducted at least 5 days but no longer than 7 days after the last dose of study drug.

Oxygen supplementation has been proven to be effective in hypoxemic COPD patients by increasing oxygenation and reducing dyspnea. In clinical practice there are three common oxygen delivery systems used: continuous oxygen flow (CF), demand oxygen delivery with liquid oxygen (DDL) and demand oxgen delivery with portable oxygen concentrator (DDC). The CF involves considerable wastage of oxygen because oxygen is supplied during in- and exhalation. Demand oxygen delivery saves oxygen and results in a comparable oxygen saturation at rest in COPD patients. However, it is unknown, if oxygen supplementation via demand oxygen delivery is also sufficient during exercise in hypoxemic COPD patients. In addition, it has to be considered that the lower weight of demand oxygen delivery system might enable patients for higher physical activity level and mobility in daily life. The effects of These three oxygen delivery systems shall be investigated by a randomized, controlled cross-over Trial. Every patient has to perform an Incremental Shuttle Walk Test and three Endurance Shuttle Walk Tests with three different oxygen supplementation (via CF, DDL or DDK) in randomized order.

There is a growing body of evidence demonstrating that older adults with COPD have important problems with their balance and a high incidence of falls compared to those of a similar age. This research will explore the feasibility and preliminary effects of a tailored 6-month home balance exercise program for reducing falls in older adults with COPD.
