Filter by:The purpose of this study is to evaluate discontinuation rates of roflumilast using an up-titration regimen for the first 4 weeks of treatment compared with continuous treatment of 500 μg one daily (OD) during the entire 12-week main period, and to evaluate if participants who do not tolerate roflumilast 500 μg OD have a drug exposure with 250 μg roflumilast OD similar to that observed in other participants with the 500 μg OD dose.
Budesonide + Procaterol HFA MDI is a novel asthma product containing both budesonide and procaterol in a single inhaler. Budesonide is a corticosteroid that treats underlying airway inflammation in asthma. Procaterol is a direct acting sympathomimetic with predominantly Beta-adrenoceptor stimulant activity selective to Beta-2 receptors (a Beta-2 agonist). It is used as a bronchodilator in the management of reversible airways obstructive pulmonary disease. Budesonide and Procaterol therefore have complementary effects, treating two different components of asthma.
The study evaluates the efficacy of fluticasone furoate/umeclidinium bromide/vilanterol (FF/UMEC/VI) to reduce the annual rate of moderate and severe exacerbations compared with dual therapy of FF/VI or UMEC/VI in subjects with COPD. Published studies which assessed the use of an 'open' triple therapy (use of Inhaled Corticosteroid [ICS]/ Long-acting Muscarinic Receptor Antagonists [LAMA])/ Long Acting Beta-Agonist [LABA] delivered via multiple inhalers) in moderate-severe COPD patients, reported improvements in lung function, Health Related Quality of Life (HRQoL), hospitalization rates and rescue medication use, compared to dual therapy (ICS/LABA) or LAMA alone. These studies have also shown similar safety profile with dual or monotherapy doses for periods of up to one year. Given the clinical experience with FF, UMEC and VI, and that the associated risks with these compounds are anticipated from their known pharmacology, the potential benefit of a new therapy option in patients with moderate to severe COPD supports the further development of the closed triple combination (delivered via one inhaler). In the current study subjects meeting all inclusion/exclusion criteria will complete 2-week run-in period; 52 week treatment period and a 1-week safety follow-up period. Eligible subjects will be randomized to one of the following double-blind treatment groups FF/UMEC/VI 100 micrograms (mcg)/62.5 mcg/25 mcg once daily (QD), FF/VI 100 mcg/25 mcg QD, or UMEC/VI 62.5 mcg/25 mcg QD
Propeller Health is collaborating with the City of Louisville and other local partners to carry out a focused demonstration project that will evaluate the effectiveness of the Propeller Health approach to asthma management while exploring means to use real-time data on asthma exacerbations in a public health setting. The Asthma Data Innovation Demonstration Project (ADID) will use wireless sensor technology to develop spatial and temporal data on the use of rescue inhalers by 120 study subjects with asthma in the Louisville metropolitan area. Propeller Health will process these data to support two general strategies. Asthma self management: Rescue inhaler actuation data will be compiled into individualized feedback reports to support asthma self management. Propeller Health will combine information on individual rescue inhaler actuations with evidence-based asthma management tips into real-time reports that will be provided to subjects. ADID staff will evaluate any resulting improvements in asthma control that may be based on this information. Subjects may share reports with their healthcare providers. Municipal purposes: The second strategy is to provide aggregated and de-identified, spatial and temporal asthma rescue inhaler actuation data to City personnel and authorized public health researchers in Louisville. These data will show the times and locations of the use of rescue inhalers by the 120 study subjects throughout the greater Louisville area. ADID staff will work with City personnel and researchers to investigate how this unprecedented level of detailed information on exacerbations can be used best to increase public awareness of environmental triggers while supporting public health surveillance efforts around respiratory diseases.
Patients with chronic obstructive pulmonary disease suffer from significant cardiovascular morbidity and mortality. This study wants to determine whether chronic obstructive pulmonary disease might be a risk factor for coronary atherosclerosis and other cardiac markers independent of conventional cardiovascular risk factors. The study is designed as a retrospective matched case-control study with follow-up via telephone interview.
The primary aim of this study is to assess the feasibility of conducting a trial to investigate the effectiveness of a physical activity intervention (physical activity consultation and a pedometer-based walking programme) versus pulmonary rehabilitation in improving physical activity in COPD. Objectives are: (i) to assess the feasibility (patient recruitment, adherence, drop-outs and adverse events) of delivering a physical activity intervention in the COPD patient population versus pulmonary rehabilitation; (ii) to explore users perceptions relating to satisfaction and benefits of a physical activity intervention versus pulmonary rehabilitation; (iii) to investigate between and within group change in physical activity, exercise capacity, quality of life, self-efficacy and changes in the transtheoretical model with the physical activity intervention versus pulmonary rehabilitation; and (iv) to examine the cost of delivering a physical activity intervention versus pulmonary rehabilitation for patients with COPD. The hypothesis for this study is that it will be feasible to conduct a trial that will investigate the effectiveness of a physical activity intervention (physical activity consultation and a pedometer-based walking programme) compared to pulmonary rehabilitation for improving physical activity in COPD. The study will provide important information about interventions designed to promote and maintain physical activity, improve patient outcomes and increase patients' choice relating to exercise and physical activity interventions. It will provide a rationale and data for an adequately powered clinical trial evaluating the effects of a physical activity intervention.
Comparing the efficacy of Symbicort® pMDI and Formoterol Turbuhaler in reducing exacerbations in patients with Chronic Obstructive Pulmonary Disease (COPD).
Obstructive sleep apnea (OSA) is the most common type of sleep apnea and is caused by an obstruction of the upper airways. The obstruction results in periods of intermittent hypoxia and re-oxygenation, which lead to increased oxidative stress, increased inflammation, endothelial dysfunction, and insulin resistance. Chronic obstructive pulmonary disease (COPD) is a lung disease that leads to poor airflow. This disease leads to systemic hypoxia, reduced oxidative capacity, and increased inflammation. The direct cause of OSA and COPD is unclear, but OSA and COPD may be linked to other comorbid conditions such as obesity and type II diabetes. Upon onset of OSA and COPD, metabolic disturbances associated with obesity and type II diabetes can be exacerbated. Obesity is a condition characterized by an increase in visceral fat, elevated plasma levels of free fatty acids, inflammation, and insulin resistance. Although the effects of body fat distribution have not been studied in these patients, an increase in both subcutaneous and abdominal fat mass in non-OSA older women was shown to increase morbidity and mortality. Fat/adipose tissue is an active tissue capable of secreting proinflammatory cytokines such as tumor necrosis factor (TNF)-alpha and interleukin (IL)-6, reactive oxygen species and adipokines. Particularly, abdominal fat is a prominent source of pro-inflammatory cytokines, which contributes to a low grade, chronic inflammatory state in these patients. Additionally, an increased inflammatory state is associated with reduced lean body mass, and together with elevated circulating free fatty acids may increase the occurrence of lipotoxicity and insulin resistance. Thus, increased fat deposition is associated with a poor prognosis in OSA and COPD patients and therefore it is of clinical and scientific importance to understand the changes in fat metabolism and digestion as a result of OSA and COPD. It is therefore our hypothesis that fat synthesis and insulin resistance is increased and whole body protein synthesis is decreased in OSA and COPD patients, leading to a poor prognosis.
The aim of this study is to assess the efficacy of a rehabilitation protocol based on individualized combined eccentric and concentric cycle ergometer training compared to classical concentric cycle training among patients with either coronary artery disease (CAD) or chronic obstructive pulmonary disease (COPD). This study will therefore evaluate the efficacy of combined eccentric/concentric training on physical capacity and overall autonomy, and will analyse the adaptive mechanisms with regard to both adaptation to cardiac and muscular effort and tolerance.
The purpose of the study is to determine if benralizumab reduces COPD exacerbation rate in symptomatic patients with moderate to very severe COPD who are receiving standard of care therapies.
