Active clinical trials for "Lung Diseases, Obstructive"

In 2005, more then one-third of Canadians were burdened with one or more chronic diseases. Patients with one chronic disease often have, or are at risk for, another chronic disease. This group of complex patients represents a substantial challenge to healthcare resources. For patients in rural communities, the opportunity to attend ambulatory care clinics is not always an option. Additionally, the opportunity for rural patients to receive quality care close to, or within their homes, is of great benefit as it reduces the need for extensive travel and the potential burden of clinical visits. The use of telehealth has been identified as an effective modality for chronic disease management and is actively promoted by national organizations as having great promise for health service delivery in rural areas. The Internet as a mode for healthcare delivery has numerous advantages: 1. it is ubiquitous with increasing access in all age groups, 2. it is inexpensive, 3. it facilitates both patient data transfer and patient feedback, thereby supporting patient self-management, 4. it is scalable to large patient volumes, 5. it delivers health care directly to the patient and 6. it requires minimal set-up for patients with current Internet access. The investigators propose to develop and evaluate a multi-chronic disease management program delivered through the Internet (with telephone supports) focused on high-impact chronic diseases targeted to patients in rural communities. This study will consist of a single-blinded randomized controlled trial to investigate the efficacy of the iCDM in 318 patients with two or more of the target chronic diseases living in rural areas. Within this Aim, the investigators will be able to address the following research questions: Q1. What is the effect of iCDM on healthcare utilization and patient self-management outcomes? Q2. What is the long-term compliance to the iCDM? Q3. What is the level of patient and provider satisfaction?

This study is designed to explore a new approach to help people with chronic obstructive pulmonary disease (COPD) become more physically active. Through weekly telephone sessions with a health coach utilizing motivational interviewing, participants will be empowered to set goals for increased physical activity (emphasis on walking). The objective of the study is to determine if telephone-based health coaching is a reasonable and effective way to increase physical activity, as measured by a gold-standard activity monitor, in people with COPD.

The purpose of this study is to evaluate the safety and efficacy of inhaled PT005 MDI compared to placebo and Foradil Aerolizer in patients with moderate to severe chronic obstructive pulmonary disease (COPD).

The primary objective of this study was to compare the long-term (12-week) bronchodilator efficacy and safety of ipratropium bromide / salbutamol combination administered by the Respimat® 40 mcg / 200 mcg (one inhalation q.i.d.) to COMBIVENT Inhalation Aerosol (two inhalations q.i.d.), ipratropium bromide Respimat® (one inhalation q.i.d.) and Placebo formulations of each in patients with Chronic Obstructive Pulmonary Disease (COPD). An additional objective was to show the superiority of Combivent Respimat as compared to ipratropium bromide (40 mcg) Respimat. Steady state pharmacokinetics over one dosing interval following four weeks of therapy were also characterized.

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.

This study is designed to assess the effect of QVA149 (110/50 ug q.d.) versus placebo on pulmonary function and average physical activity levels in patients with moderate to severe Chronic Obstructive Pulmonary Disease (COPD).

The effectiveness of clinic-based pulmonary rehabilitation in advanced Chronic Obstructive Pulmonary Disease (COPD) is well established, but few data exist for less severe patients treated in alternative settings. The purpose of this study was to investigate whether a novel, community-based exercise program was feasible and effective for patients with moderate COPD.

This multicenter study will be conducted to compare the effect of FF/UMEC/VI with FF/VI plus UMEC on lung function after 24 weeks of treatment. This is a phase IIIB, 24-week, randomized, double-blind, parallel group multicenter study. This study will test the hypothesis that the difference in trough forced expiratory volume in one second (FEV1) between treatment groups is less than or equal to a pre-specified non-inferiority margin. Alternatively, this study will also test the hypothesis that the difference between treatment groups is greater than the margin. The triple therapy of FF/UMEC/VI in a single inhaler is being developed with the aim of providing a new treatment option for the management of advanced Global Initiative for Chronic Obstructive Lung Disease (GOLD) Group D COPD which will reduce the exacerbation frequency, allow for a reduced burden of polypharmacy, convenience, and improve lung function, health related quality of life (HRQoL) and symptom control over established dual/monotherapies. This study has a 2 week run in period where subjects will continue to have their existing COPD medications. At randomization, subjects will discontinue all existing COPD medications and will be assigned to treatment of FF/UMEC/VI, 100 microgram (mcg)/62.5 mcg/25 mcg and placebo or FF/VI, 100 mcg/25 mcg and UMEC, 62.5 mcg in a 1:1 ratio for 24 weeks. Subjects will have clinical visits at Pre-Screening (Visit 0), Screening (Visit 1), Randomization (Week 0, Visit 2), Week 4 (Visit 3), Week 12 (Visit 4) and Week 24 (Visit 5). A follow-up visit will be conducted at 1 week after the end of treatment period or after early withdrawal visit. Approximately, 1020 subjects will be enrolled in this study. There will be two pharmacokinetic (PK) groups (subset A and subset B). Approximately 120 subjects will be assigned to subset A and approximately 60 subjects will be assigned to subset B. The total duration of subject participation will be approximately 27 weeks, consisting of a 2-week run-in period, 24-week treatment period and a 1-week follow-up period.

What are the differential effects of beta-blockers on lung and heart function during exercise in chronic obstructive pulmonary disease (COPD)? COPD is a major cause of illness and death. Not only do these individuals suffer from lung disease, but COPD often leads to other illnesses, particularly heart disease. Beta-blockers very successfully treat heart disease. It is therefore logical that one would want to use this treatment in COPD patients with heart disease too. However, there has always been concern that beta-blockers could cause significant problems in COPD by worsening lung function, as these can have the opposite effect to inhalers used to treat COPD that open up airways. Pointedly, there is increasing evidence that despite this problem, COPD patients who have been prescribed beta-blockers have been shown to gain benefit particularly in terms of preventing death. In this study, the investigators therefore want to examine which beta-blocker might be the safest for COPD patients, as each work slightly differently. Some beta-blockers may have a more beneficial effect on airways than others, whilst still benefitting the heart. The investigators will study two different beta-blockers; one that potentially narrows airways and one that potentially opens airways. The investigators will be using cardiopulmonary exercise testing (an exercise bike that measures both heart and lung function during exercise) to look for differences between both beta-blockers primarily in terms of lung function but also with information about the heart. The investigators will recruit people with moderate to severe COPD who are able to complete a cycle exercise test through their respiratory research department. The study will last for 10-12 weeks with 5 main visits to the department for serial exercise tests, breathing tests, simple heart function tests and simple blood tests that will tell the investigators what other effects these beta-blockers are having on the heart and lungs.

A number of studies have documented poor sleep quality and troublesome symptoms (breathlessness, cough and sputum production) upon awakening in patients with COPD. However, the investigators know very little about measurements of respiratory mechanics (i.e., lung volumes, respiratory pressures, diaphragm function, etc) during sleep in these patients. The investigators also know little about how modern bronchodilator therapies, or the timing of when they are taken, affect respiratory mechanics during sleep or the severity of early morning respiratory symptoms. COPD is often treated with inhaled bronchodilator medications which are used to open up airways and make it easier for air to get in and out of the lungs. The investigators are studying the effects of a new inhaler that contains two different types of long-acting bronchodilator: formoterol [a long-acting beta2-agonist (LABA)] and aclidinium bromide [a long-acting muscarinic antagonist (LAMA) or anticholinergic]. Initial studies have shown that this combination therapy taken twice daily can improve some lung function measurements and respiratory symptoms in patients with moderate to severe COPD. There are also reports that evening administration of this medication may provide important advantages in patients with dominant nighttime and early morning symptoms. It is thought that sustained bronchodilation and lung deflation during the night may improve respiratory mechanics, diaphragmatic function, pulmonary gas exchange, sleep quality, and reduce severity of morning symptoms. This study will be the first to explore the effects of a nighttime dose of aclidinium/formoterol combination therapy on detailed measurements of respiratory mechanics and early morning symptoms in COPD. This study will also give us a better understanding of the mechanisms of early morning respiratory symptoms and their improvement with bronchodilators.
