Filter by:To determine the effects of 2 months therapy with simvastatin 40mg once per day compared to placebo in a double-blind placebo-controlled study of patients with COPD.
The primary objective is to comparatively evaluate the isolated effects of a long-acting beta2-adrenergic (formoterol fumarate 12µg b.i.d. via Aeroliser) and combined with a long-acting anti-cholinergic (tiotropium bromide 18µg o.d via Handihaler) on breathlessness, dynamic hyperinflation and exercise tolerance in patients with advanced, but stable, chronic obstructive pulmonary disease. The study hypothesis is that combining long acting bronchodilators with different action mechanisms would promote synergistic effects on clinical outcomes.
This study will determine if a rehabilitation exercise program can help people with pulmonary hypertension (PH) increase their physical activity. Patients with PH have an increase in blood pressure in the pulmonary blood vessels (artery, vein or capillaries) that leads to shortness of breath, dizziness, fainting and other symptoms. Healthy volunteers and people with pulmonary hypertension between 21 and 75 years of age may be eligible for this study. All participants undergo the following tests and procedures: - Medical history and physical examination - 6-minute walk test: Subjects walk as fast as they can for 6 minutes on a walking track to determine their ability to participate in physical activity. - Questionnaires: Subjects complete nine questionnaires related to their fatigue, daily physical activity, mood, and so forth. - Maximum treadmill test: The exercise begins at an easy level and gradually increases until the subject says he or she can no longer continue or the investigator decides it is not safe to continue. Subjects are fitted with a mask, electrodes and light sensors to measure how well the heart is working and how well the muscles use oxygen. Patients with pulmonary hypertension undergo the following additional procedures: - Activity monitoring: Patients wear a monitor for 3 days that measures movement and heart rate. - Group assignment: Patients are randomly assigned to Group 1 (education plus aerobic exercise) or Group 2 (education followed by exercise). - Group 1 patients will attend classes three days a week at either Inova Fairfax Hospital Pulmonary Rehabilitation Center or The National Institutes of Health for 10 weeks. Two sessions a week will include a 1 hour education session as well as a 30-45 minute track or treadmill exercise session. The third session will only include exercise. During the education patients will learn about a healthy lifestyle with pulmonary hypertension. After the 10 weeks of education and exercise, subjects repeat the 6-minute walk test, maximum treadmill test and questionnaires. - Group 2 patients participate in 2; 1-hour educational session at either the Inova Pulmonary Rehabilitation Center or The National Institutes of Health for 10 weeks. After the classes, they repeat the 6-minute walk test, maximum treadmill test and questionnaires. The following 10 weeks will consist of 3 days a week of 30-45 minute track or treadmill walking at either Inova or NIH, after which they again repeat the questionnaires, treadmill and walk tests.
This study evaluated the 1 year safety, tolerability and efficacy of indacaterol against placebo in the treatment of Chronic Obstructive Pulmonary Disease (COPD) patients
The purpose of this study is to elucidate whether combination of usual pulmonary rehabilitation and neuromuscular electrical stimulation of quadriceps may improve exercise capacity in patients affected by chronic obstructive pulmonary disease (COPD).
Spirometry is a useful clinical tool for the assessment and monitoring of lung disease, however, it does not provide information on peripheral airways resistance. On the contrary, impulse oscillometry (IOS) may provide information not only on airway resistance (Rrs) but also on the elastic properties of the lung (Xrs). In addition, multiple breath nitrogen washout (MBNW) utilizes the exhalation of nitrogen gas from the airways to determine changes in lung ventilation and derive small airways indices (that tells us about small airways calibre). This method, like IOS, allows a precise assessment of small airways function. Even though patients with asthma may show some reduction of the caliber of the small airways these changes are more a feature of patients with COPD. The study team hypothesize that IOS and MBNW measurements may detect these differences and provide different resistance profiles for asthma and COPD. Furthermore, the study team would like to investigate the relationship between airway inflammation and small airway disease by measuring exhaled nitric oxide (NO) at multiple exhalation flow rates. This technique allows the partitioning of NO produced in the central airways from that generated more peripherally in the lung, providing valuable information on the activity of inflammation in different parts of the respiratory system. The study team hope that the combined use of IOS, MBNW and NO will identify a possible correlation between inflammation and small airway dysfunction.
The purpose of this study is to evaluate the efficacy and safety of GSK233705B compared with placebo in subjects with COPD.
Most people undergoing lung transplantation have chronic obstructive pulmonary disease (COPD), a disease in which the lung airways are partly damaged and obstructed, making it difficult to breathe. This study will enroll people with COPD who are undergoing a lung transplant to examine how their quality of life changes after the transplant procedure.
GSK961081 is a potent dual pharmacophore that demonstrates both antimuscarinic and beta-agonist pharmacology in preclinical studies, both pharmacologies being of long duration. If reproduced in man, GSK961081 has the potential to deliver a medicine that can be given once daily. The bronchodilatation after inhalation of single doses of GSK961081 alone and in the presence of the short acting beta agonist salbutamol and the short acting muscarinic antagonist, ipratropium bromide will be measured in this study. Any residual bronchodilatation post-inhalation of GSK961081 and demonstrated by addition of salbutamol or ipratropium bromide may provide an indirect assessment of the beta-agonist and antimuscarinic components of GSK961081
This purpose of this study is to assess the safety of ramelteon, once daily (QD), in subjects with chronic obstructive pulmonary disease.
