Filter by:This study evaluated the safety and efficacy of four doses of TD-4208 and a placebo product when administered once daily for 28 days using a jet nebulizer to patients with moderate to severe chronic obstructive pulmonary disease.
The study is performed to characterize the pharmacokinetics of glycopyrrolate bromide after single administration of CHF 5993 pressurised Metered Dose Inhaler (pMDI) in subjects with different level of renal impairment in comparison with matching healthy volunteers. Moreover, the safety and tolerability of the study drug will be also evaluated.
COPD patients experiment a peripheral muscle dysfunction which impact their exercise tolerance and health-related quality of life. The capillary to fiber interface is reduced and impact the exercise capacity of the patients. While the muscle capillary creation in response to exercise training is blunted in COPD patients, the maturation of the neo-capillaries could also be blunted and contribute to the impaired aniogionenesis in patients. Because the capillary maturation is a sensitive and dynamic process, only different modalities of exercise training and multiple time-points of measures would allow to capture this microvascular adaptation. Aim of the study : Compare the muscle capillary maturation in response to training at 5 and 10 weeks, in sedentary healthy subject trained at the intensity of the ventilatory threshold (60-65% of VO2max), versus :- COPD patients trained at a similar intensity (60-65% of VO2max)- COPD patients trained at a similar absolute intensity (90% of VO2max).
Study for subjects 40 to 65 years-old with a diagnosis of moderate to severe COPD. Aclidinium bromide 400 mcg 2x a day will be given as an active comparator.
This study involves development and testing of a patient and family-centered transitional care program for patients who are hospitalized with Chronic Obstructive Pulmonary Disease (COPD) exacerbations. The study intervention includes tailored services to address individual patients' biopsychosocial needs, starting early during hospital stay and continuing for 3 months post hospital discharge. The study hypothesis is that compared to usual care, the study intervention will : a) Improve patient health- related quality of life and survival, and reduce use of hospital and emergency room visits; b) result in improved patient experience, self- confidence, and self-care behaviors; c) result in improved family caregivers coping skills, self-confidence, and problem solving skills to address patient barriers to care and treatment.
A standardized diagnostic strategy of pulmonary embolism will be applied to eligible patients, incorporating a clinical probability score (revised Geneva score), plasma D-dimer assay and if necessary, a multidetector-row CT angiography thoracic and venous ultrasound of the lower limbs. All the patient with a pulmonary embolism diagnosed or not, will be followed for 3 months.
Initiatives aimed at reducing Emergency Department (ED) wait times and improved community health initiatives are major priorities in Canada. Three of the most common chronic diseases worldwide are Diabetes Mellitus (DM), Congestive Heart Failure (CHF) and Chronic Obstructive Pulmonary Disease (COPD). These diseases are on the rise and currently cost the Canadian health care system billions of dollars every year including the cost of hospitalizations and ED visits. The existing health care system does not have the resources and manpower to effectively care for these patients in the future. Paramedics are currently employed to provide Emergency Medical Services in remote, rural and urban settings in Canada. They are highly trained health care practitioners that are mobile in the community and currently work in a physician medically delegated act model and therefore are positioned to take on new collaborative roles to deliver patient care in the community setting. Increased community paramedic care could decrease the utilization of the health care system resources for patients with chronic disease. Using a randomized control trial design we will attempt to answer the question of whether whether non-emergency community paramedics conducting home visits to undertake assessments and evidence-based treatments of patients in partnership with family doctors will decrease the rate of patient hospitalization.
Chronic Obstructive Pulmonary Disease (COPD) is a leading and still increasing cause of disease and death worldwide, affecting those in both developed and developing countries. This imparts a massive burden of ill health, in turn imposing huge healthcare costs to society. For effective treatment of COPD (as opposed to providing short term relief) early disease must be targeted. The small airways of the lung (those less than 2mm) are the first affected in COPD, but current methods to assess their function are relatively insensitive. There is therefore a need for new, accurate methods for detection of small airway dysfunction with sensitivity to shortterm change and regional discrimination. In previous studies with hyperpolarised (HP) 3He MRI in smokers with normal pirometry and patients with early stage COPD, we showed sensitivity to early changes in lung ventilation and structure. The hyperpolarised gas MRI technique is safe. In particular, the lack of ionizing radiation permits patients to be imaged on multiple occasions. This and its inherent sensitivity to regional lung ventilation and function make it an ideal imaging tool for the assessment of novel lung therapies for diseases of the small airways. The purpose of this pilot study is to determine short and long term reproducibility of a comprehensive set of functional imaging data; using hyperpolarised gas MRI, conventional MRI and lung physiology measurements in patients with moderate to severe COPD. In addition,how sensitive the imaging techniques are to changes in lung function after treatment with a standard (bronchodilator) inhaler will also be assessed. This pilot study will serve as a platform for future larger scale studies, aimed at better understanding of and intervention in early COPD.
Macrolides are potent inhibitors of cytochrome P450 isoenzyme 3A4（CYP3A4）and thus interfere with the pharmacokinetics of many other drugs that are metabolised by this enzyme like theophylline.The aim of this study is to determine whether azithromycin can effect theophylline metabolism in patients.
