Filter by:This is a clinical research study to assess whether after exhaling a single cigarette smoke through the nose there are changes in the inflammatory cells and proteins of nasal secretions. A single blood sample from each subject will be stimulated with cigarette smoke in the laboratory to see the effects on inflammatory blood cells. Comparison of findings between smokers with COPD and "Healthy" smokers will be carried out. We hypothesize that some subjects have amplified inflammatory response to a single cigarette, and these will be those subjects who develop chronic obstructive pulmonary disease (COPD) after decades of smoking. We hope to develop an acute challenge model that relates to the causation of COPD. When studying the effects of new drugs, these may be detected in small numbers of patients in a challenge situation, when we would need to study many more unchallenged patients to demonstrate drug effects. In clinical research on asthma and allergy, the nasal allergen challenge has been a very successful model, and we hope to validate a comparable model for COPD.
The objective of this trial is to determine whether tiotropium inhalation capsules (Spiriva, Bromuro de Tiotropio), compared to placebo, enhances the improvement in exercise tolerance seen in patients with chronic obstructive pulmonary disease (COPD) who participate in pulmonary rehabilitation.
This study was conducted to evaluate the safety and pharmacokinetics of an echocardiographic contrast agent, AI-700, in patients with moderate to severe chronic obstructive pulmonary disease (COPD) and/or congestive heart failure (CHF).
The objective of this trial is to compare the total and regional deposition of aerosol in the lungs and oropharynx of patients with COPD at 3 different inspiratory flow rates following inhalation of Berodual delivered via the Respimat inhaler and Berodual? delivered via an HFA-metered dose inhaler.
The primary objective of this study is to demonstrate the superiority of tiotropium compared to placebo in the treatment of patients with COPD and a concomitant diagnosis of asthma
Approximately 20% of patients with chronic obstructive pulmonary disease (COPD) have major depression, a condition that contributes to suffering but also to poor treatment adherence leading to increased disability and morbidity. This study investigates the effectiveness of a care management intervention aimed at facilitating adherence to a treatment algorithm based on the Agency for Health Care Policy and Research (AHCPR) guidelines. The investigators hypothesize that this intervention, in comparison to usual care, will increase the prescription of adequate antidepressant treatment by physicians, enhance treatment adherence by patients, and reduce depressive symptoms, suicide ideation, and disability at a 28-week follow-up period.
This study evaluates the effect of two medicines on COPD (Chronic Obstructive Pulmonary Disease) exacerbations. This study will last up to 56 weeks, and subjects will visit the clinic 10 times. Subjects will be given breathing tests and will record their breathing symptoms daily on diary cards. All study related medicines and medical examinations will be provided at no cost. The two drugs used in this study have been approved by the FDA for use in patients with COPD.
This is a 28-day, placebo controlled clinical study assessing the safety, tolerability anti-inflammatory effect and pharmacokinetics of SB681323 in patients with COPD (Chronic Obstructive Pulmonary Disease).
The primary objective of this trial is to determine whether daily treatment with tiotropium (Spiriva®, Bromuro de Tiotropio®) inhalation capsule via HandiHaler® reduces the rate of decline in lung function over time in patients with COPD.
The objective of this study is to determine if tiotropium (Spiriva, Bromuro de Tiotropio) 18 mcg once daily by oral inhalation compared to placebo increases the magnitude of daily physical activity observed in COPD patients, measured using an accelerometer.
