Active clinical trials for "Lung Diseases, Obstructive"

The purpose of this study is to characterize the pharmacodynamic profile of Formoterol Fumarate and Foradil Aerolizer

Computational Fluid Dynamics (CFD) is a new functional imaging method. Since CFD is very sensitive to detect small changes, it might be worthwhile to study the acute effect of formoterol and budesonide combination therapy (Symbicort® forte Turbohaler®) on the upper airway dimensions in severe COPD patients (GOLD III). The increased sensitivity of this technique makes it possible to detect changes in airway caliber in early stages. The regional distribution of resistance and the change in this parameter will provide more insight into the mode of action of the product.

National Institute for Clinical Excellence (NICE) guidelines recommend high dose inhaled steroids for patients with moderate to severe Chronic Obstructive Pulmonary Disease (COPD, a common chronic disease related to smoking) who are having two or more exacerbations requiring treatment with antibiotics or oral steroids in a 12 month period. The preparations licensed for this indication commercially available are Symbicort® and Seretide®. High dose inhaled steroids (contained in both) can cause suppression of the adrenal glands. The investigators want to assess adrenal suppression caused by the two preparations and compare. The results could guide investigators in prescribing these preparations.

This study is primarily a safety study. The primary and secondary endpoints are based on 24-hour Holter monitor assessments obtained on Day 14 relative to baseline.

The purpose of this study is to evaluate the 24-hour spirometry effect (FEV1) of FF/VI 100/25mcg once daily compared with Fluticasone Propionate/Salmeterol 250/50mcg twice daily over a 12-week treatment period in subjects with COPD.

The aim of this study is to establish associations between blood and urine markers of bone metabolism with histomorphometric changes (changes in the actual bone structure) resulting from short term oral prednisolone treatment in patients with COPD (chronic obstructive pulmonary disease).

The purpose of this study is to determine if ramelteon has respiratory depressant effects in subjects with moderate to severe chronic obstructive pulmonary disease.

To evaluate the efficacy and safety of LAS 34273 compared to placebo in patients with moderate to severe COPD during one year of treatment.

This is a randomized, double-blinded, placebo-controlled trial of oral Cyclosporine A (CsA) in patients with advanced stage chronic obstructive pulmonary disease. The purpose of the study is to evaluate the safety and effectiveness of CsA as a therapy for the adaptive immune response in advanced stage Chronic Obstructive Pulmonary Disease (COPD). Subjects between 45 and 80 years of age with a confirmed diagnosis of advanced stage COPD, not responsive to conventional inhaler therapy, who meet all the study requirements, will be enrolled in this study. A total of 30 subjects of either sex will be enrolled in this study.

Breathing discomfort (dyspnea) and activity limitation are dominant symptoms of chronic obstructive pulmonary disease (COPD) and contribute to poor health-related quality of life in this population. Several small, uncontrolled studies and published case reports have provided evidence that inhaled fentanyl, a powerful pain relieving (opioid) medication, may be used to effectively reduce breathing discomfort in patients with advanced disease. However, the mechanisms of this improvement remain unclear. Therefore, the investigators plan to conduct the first randomized, double-blind, placebo-controlled, crossover study designed to explore the possible mechanisms of action of inhaled fentanyl on activity-related dyspnea and exercise performance in patients with advanced COPD.
