Filter by:The purpose of the study is to provide long term safety data of NVA237. This study will assess the safety and tolerability of a single dose strength of NVA237.
The overall objectives of our study are to determine the capabilities of hyperpolarized 129Xe MRI to measure lung function and its potential to sensitively detect pulmonary disease and its progression in COPD. We hypothesize that measurement of alveolar surface area, septal thickness, and capillary transit time measured with hyperpolarized 129Xe will correlate better with quality of life measures in COPD subjects than traditional diagnostic measures such as spirometry and Computed Tomography.
The aim of this study is to investigate the development of partial pressure of carbon dioxide during the 6-min walking test and during night in Chronic Obstructive Pulmonary Disease (COPD)-patients (GOLD stage IV). Therefore the partial pressure of carbon dioxide, oxygen saturation and the heart rate are registered by a device called "Sentec" during the mentioned periods. In addition a measurement of activity is realised by an activity monitor ("Sensewear").
The overall objective of this study is to assess efficacy and safety of 12 weeks, once daily, orally inhaled co-administration of olodaterol 5 µg (delivered by the Respimat® Inhaler) and tiotropium (delivered by the Handihaler® as Spiriva Handihaler®), compared to tiotropium (Spiriva Handihaler®) monotherapy on lung function in patients with COPD.
FEELBREATHE®, a nasal ventilatory restriction device, used during an exercise test in treadmill produces changes on breathing efficiency in patients with Chronic Obstructive Pulmonary Disease (COPD). 20 men with COPD with a forced expiratory volume in the first second between 30% and 70% of its predicted value were selected. Then, a maximal incremental cardiopulmonary exercise test was performed to determine ventilatory and cardiac parameters. During the second day, each participant conducted two tests with 30 min of rest between them. Exercise protocol was an identical walk on a treadmill for 10 minutes at a constant rate at 50% of VO2peak. Each test was performed randomnly in two different conditions: 1) oronasal breathing (ONB); and 2) nasal breathing through the FB.
The overall objective of this study is to assess efficacy and safety of 12 weeks, once daily, orally inhaled co-administration of olodaterol 5 µg (delivered by the Respimat® Inhaler) and tiotropium (delivered by the Handihaler® as Spiriva Handihaler®), compared to tiotropium (Spiriva Handihaler®) monotherapy on lung function in patients with COPD.
Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory disease of the bronchi with an increasing prevalence. By 2020, the mortality related to COPD is expected to become the 3rd leading death worldwide. COPD is caused by smoking in approximately 90 % of the cases. Nevertheless, COPD remains under-diagnosed and more than half of patients remain active smokers. Brittany is the second region of France facing an abnormal high death rate related to COPD. Smoking cessation is the most effective therapeutic approach to reduce the evolution of the disease, the frequency of the exacerbations and the the mortality. Besides, smoking cessation is associated with a reduced risk of cardiovascular events and cancer. Given the COPD patients' strong addiction, smoking cessation is not easily obtained in such population. Furthermore, smoking cessation has been underestimated in several studies. Most of these studies evaluated various methods of smoking cessation in COPD patients performed after an exacerbation, which has a hospitalization related mortality of approximately 10%. Thus, there is an urgent need to find effective pharmacotherapies to help COPD patients to cease smoking. Varenicline, a partial agonist at a4ß2 nicotinic acetylcholine receptors is reported to be one of the most effective pharmacotherapies for smoking cessation. However, it has never been evaluated at the acute phase of an exacerbation of COPD requiring hospitalization.
Airway remodelling is an abnormal tissue repair following bronchial inflammation, which contributes to none reversible pathological features, such as bronchial and peri-bronchial fibrosis. It also influences the prognosis of Chronic Obstructive Pulmonary Disease (COPD) and its mechanisms remain largely unknown. The role of fibrocytes has been demonstrated in the pathophysiology of asthma, lung fibrosis or pulmonary hypertension. However, the recruitment of blood fibrocytes and their involvement in COPD airway remodelling remain unknown. The main objective of the study is to analyse the distribution and quantify the number of the peri-bronchial and blood circulating fibrocytes in patients with different stages of COPD compared to control subjects.
The primary objective of the study is to test the hypothesis that lung hyperinflation contributes to cardiac dysfunction in COPD and that the treatment of lung deflation with FF/VI Inhalation Powder 100/25 mcg administered once daily (QD) will result in the reversal of this cardiac dysfunction compared with placebo. This will be assessed by measures of right and left global and regional systolic and diastolic cardiac function as assessed using a 30 minute CMR. A secondary objective will be to investigate the effect of FF/VI inhalation powder 100/25mcg QD on measures of arterial stiffness in the form of pulse wave analysis and distensability in the pulmonary and systemic circulation.
This is a double-blind, single dose (four inhalations), four-way cross over study in healthy subjects that will assess the systemic pharmacokinetics (PK) and systemic pharmacodynamics (PD) of Fluticasone Furoate, (FF), Umeclidinium, (UMEC) and Vilanterol (VI). Study drug will be delivered through a novel single-step activation dry powder inhaler (NDPI) which has a two strip configuration. The NDPI will be configured with different combinations of each compound and also a new blend of UMEC/VI inhalation powder within a single strip of the NDPI device. Study drug will be administered through the inhaled route to healthy subjects in single doses (four inhalations). Each subject will receive treatment in a randomized order Treatment A FF (400 microgram [µg]) and UMEC (500 µg)/VI (100 µg), Treatment B UMEC (500 µg) and VI (100 µg), Treatment C FF (400 µg) and VI (100 µg) and Treatment D FF (400 µg) and UMEC (500 µg) over four treatment periods. Each treatment period will be separated by a washout of 7 to 21 days. After the four treatment periods, a follow up visit will take place 7 to 21 days following the final dose of study medication and the maximum duration a subject will be involved in the study is eighteen weeks. Pharmacokinetics will be assessed by the measurement of plasma and urine concentrations of FF, UMEC and VI. Safety and PD will be monitored using blood glucose, serum potassium, heart rate, 12-lead ECGs and clinical laboratory tests. Plasma samples for PK will be collected throughout the study, urine, blood glucose, serum potassium, heart rate, 12-lead ECGs and clinical laboratory tests will be assessed on Day 1 only. AEs will be assessed throughout the study.
