Filter by:This study is being done to examine the influence of Tiotropium (good or bad) on heart function at rest and during exercise in patients with moderate to severe chronic obstructive pulmonary disease (COPD).
To evaluate the efficacy and safety of arformoterol tartrate inhalation solution 30μg/4mL QD (two 15μg/2mL dosed in combination) over a 24-hour period compared to arformoterol tartrate inhalation solution 15μg/2 mL BID in subjects with COPD.
This study will evaluate the safety and efficacy of QVA149 in patients with moderate to severe COPD.
To evaluate if tiotropium (Spiriva)induced bronchodilation of inspiratory capacity in patients with moderate to severe copd subjected to metronome paced hyperventilation induced dynamic hyperinflation is dependent upon the extent of underlying emphysema as determined by high resolution-thin section CT lung.
We will detect dynamic hyperinflation (DH) in 40 COPD (chronic obstructive pulmonary disease) patients with moderately severe disease using metronome paced hyperventilation (MPH) with inspiratory capacity as the primary end point. Hypothesis: Is tiotropium capable of lung volume protecting inspiratory capacity from MPH induced DH vs placebo in a randomized crossover double blinded study.
This will be a single dose Proof-of-Concept study in mild-to-moderate COPD patients. The study will investigate the safety and tolerability of QAX028 as well as the bronchodilatory effects of QAX028 compared to tiotropium and placebo in mild-to-moderate COPD patients.
To evaluate the role of inhaled corticosteroids to suppress nitric oxide gas exchange in stable patients with moderate-to-severe COPD who are current non-smokers and not on oral corticosteroids.
The investigators' aim is to study the effect of pressure support ventilation at two levels of PEEP and Pressure Support versus neurally adjusted ventilatory assist (NAVA) in COPD patients.
This study evaluated the safety and efficacy of 26 weeks treatment with indacaterol, placebo or salmeterol in patients with chronic obstructive pulmonary disease.
Smoking damages the airway epithelium. The major mechanism by which this is done is by molecules called free radicals. Our body attempts to deal with these damaging molecules in two ways. One mechanism is via the presence of protective anti-oxidant vitamins and the other is via proteins that are produced by the body to convert free radicals to safer, less reactive molecules. Vitamins in our diet play a significant role in antioxidant defenses by directly neutralizing the damaging free-radicals and by providing co-factors to cellular proteins that neutralize the free radicals. This project is designed to look at the effects of giving individuals supplemental vitamins to see if it improves their defenses against oxidant insults. The investigators plan to look at the effects of these supplements over a 30 day period and monitor the effects by measuring vitamin levels in the blood and in the lung, and by measuring the response of cells in the lung through the increase or decrease in expression of genes responsive to oxidants. To participate in this protocol, the research subject should first be enrolled in Weill-IRB protocol #0005004439 entitled "Evaluation of the Lungs of Normal (Smokers, Ex-smokers, Non-Smokers) Individuals with Segmental Bronchopulmonary Lung Lavage, Bronchial Brushing, and Bronchial Wall Biopsy", fulfilling the inclusion/exclusion criteria of that protocol. They will be invited to participate in this Vitamin protocol only if they meet the additional inclusion/exclusion criteria of this protocol.
