Filter by:The primary objective of this study is to estimate the comparative bronchodilator effect size and variability for tiotropium (Spiriva, 18 µg q.d.) with the free combination of salmeterol (Serevent, 50 µg b.i.d.) and fluticasone (Flixotide, 250 µg b.i.d.) in COPD patients. International COPD guidelines preserve milder stages of the disease (GOLD stage I and IIa) to bronchodilators and recommend the addition of inhaled corticosteroids only in those patients who have a documented spirometric response to inhaled corticosteroids and in patients with a post-bronchodilator FEV1 of less than 50% predicted, who suffer from frequent exacerbations requiring oral courses of corticosteroids. Recently published reports indicate that additional bronchodilator efficacy may be achieved when a long-acting beta agonist is combined with an inhaled corticosteroid. Steady state bronchodilation was achieved within one week with the drug combination. However, results of these studies are not consistent, and since the inclusion criteria employed were different from those utilised in the previously conducted tiotropium studies, it is difficult to generalise the observed effects to the general COPD population. In addition, no comparative data is available on the average response over the 12 daytime hours when COPD patients are active and in most need of bronchodilation. 12 hours corresponds to the dosing intervals for both salmeterol and fluticasone.
The objective of this study is to compare the bronchodilator efficacy and safety of once daily dosing of tiotropium inhalation capsules (18 ?g) and Atrovent? MDI (2 puffs of ipratropium bromide 20 ?g four times daily) in patients with chronic obstructive pulmonary disease.
To compare the efficacy and safety of tiotropium plus formoterol in comparison to salmeterol plus fluticasone in COPD patients.
The purpose of this study is to determine whether the budesonide+formoterol combination is effective in the treatment of exacerbations of COPD with a main emphasis on investigating the effects on inflammation and a secondary emphasis on clinical efficacy
The University of Ottawa and Élisabeth Bruyère Research Institute are conducting a study of preventive care for frail patients at risk of functional decline. At risk patients are assigned by chance to continue receiving their standard care from their family physician or receive additional care from a nurse practitioners and a pharmacist. In collaboration with the family physician, they develop an individualized care plan, a treatment and management road plan, for each patient, which they implement over the study period of one approximately year. The objective of the study is to compare the effectiveness of the model of care that includes the nurse practitioners and pharmacist against standard care in preventing functional decline, to determine the acceptability of this model of care to patients, their caregivers and the medical team, and to evaluate the cost implication of the program.
This is an investigator-sponsored research study to evaluate if treatment with HFA-134a beclomethasone (QVAR) has an effect on peripheral (or outer) airway inflammation and airway "remodeling" or scarring in subjects with COPD. Approximately 20 subjects with COPD will participate for approximately 7 weeks, with 10 receiving an active (BDP) inhaler with HFA-134a and 10 receiving a placebo.
The purpose of this research study is to determine whether analysis of genes in sputum is a useful noninvasive technique for measuring response to drugs in patients with COPD. We propose to use polymerase chain reaction to evaluate gene expression in induced sputum from adult current smokers with moderate COPD, adult former smokers with moderate COPD. This study is designed to determine whether changes in expression of previously-identified inflammatory markers in induced sputum can be detected in response to drug therapy in COPD and to evaluate potential differences in the expression of these markers in adult smokers with and without COPD. Pre- and post-treatment serum will be obtained to facilitate proteomic analysis of therapeutic response as well. Changes in sputum gene expression in response to treatment will be the primary outcome variable in this study. Secondary outcomes will include changes in lung function, as well as changes in induced sputum inflammation. These endpoints will be evaluated before and directly after 6 weeks of randomly-assigned treatment with either salmeterol xinafoate or fluticasone propionate/50mcg salmeterol xinafoate combination DPI bid. Endpoints will be re-evaluated following a 4 week wash-out period.
To assess the effect of up to 4 years treatment with budesonide on progression of emphysema in patients with Chronic Obstructive Lung Disease.
To humidify gases during non invasive ventilation, both to heated humidifier (HH) and heat and moisture exchanger (HME) are routinely used. Patients receiving non invasive ventilation for acute respiratory failure were randomized to HME or HH. The purpose of this study was to evaluate respiratory parameters and arterial blood gases (ABG) of patients during NIV with small dead space HME compared to HH.
PEP03 is a new chemical entity developed as a highly selective, potent, and orally active 5-LO inhibitor. PEP03 exerts its action by blocking the generation of both cysteinyl LTs and LTB4. These LTs have been associated with the inflammatory response in the lung and with the clinical sequelae, including bronchospasm. Preclinical pharmacological in- vitro, ex-vivo and in-vivo testing indicates that PEP03 has multiple beneficial actions including prevention of bronchoconstriction, and reduction of vascular leakage, cellular infiltration, and bronchial hyperresponsiveness. Clinical studies in asthmatic patients indicate that PEP03 improved FEV1 and other secondary endpoints, such as morning and evening peak flow, daytime and nighttime symptoms score, beta-agonist use, physician’s and patient’s global impression of change. Since leukotrienes have been suggested to be involved in the pathophysiology of COPD, this study is designed to explore the clinical utility of PEP03 for the treatment of moderate COPD.6; 7; 8; 9
