Filter by:A 12 week study to investigate the safety and effectiveness of arformoterol given twice daily compared to placebo in subjects with COPD.
The purpose of this study is to compare the blood levels of arformoterol tartrate inhalation solution to racemic formoterol in male and female subjects with mild to moderate Chronic Obstructive Pulmonary Disease (COPD).
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.
This purpose of this study is to assess the safety of ramelteon, once daily (QD), in subjects with chronic obstructive pulmonary disease.
Molecular mechanisms of COPD exacerbations and the modulating effect of low dose theophylline on that inflammation are elucidated in this project. NF-kappa B-dependent pathway and acetylation status of nuclear histones are to be studied.Design: controlled, prospective and randomized study with or without theophylline, a potent HDAC activator.Objectives: 1) To determine NF-kB activation, histone deacetylase (HDAC) and histone acetyl-transferase (HAT) activity in sputum macrophages and blood monocytes during an episode of exacerbation and 3 months later, once stability is achieved. To correlate these measurements with inflammatory and oxidative stress markers and with pulmonary function and clinical variables. 2) To assess the effect of theophylline on previous molecular, functional and clinical data. Method: 25 patients with COPD will be recruited during an episode of exacerbation requiring hospitalization. NF-kB activation, HDAC and HAT activity, markers of inflammation and oxidative stress will be determined with specific assays. These determinations will be repeated once the patient is stable and compared with smokers and non smoker controls with normal lung function
This study will evaluate the onset of action of indacaterol (150 and 300 µg) as compared to placebo, salbutamol 200 µg and salmeterol/fluticasone 50/500 µg
An analysis of the costs and outcomes associated with hospitalization and treatment of Levalbuterol versus Racemic Albuterol in subjects with Asthma and COPD.
This project aims to explore the relationship between Vitamin D deficiency and COPD progression via a prospective randomized placebo-controlled study. For this purpose, study was powered to 120 patients hospitalized with an exacerbation of COPD randomly assigned to a monthly oral dose of Vitamin D versus placebo. Taking into account dropouts, 182 patients are randomized during the course of the study
