Filter by:To confirm the long-term efficacy and safety of Bronchial Thermoplasty (BT) at 10 years follow-up or beyond in subjects previously enrolled in any of the following Boston Scientific-sponsored, controlled pre-approval studies: AIR, RISA and AIR2.
The study will consist of three phases: Phase A: General population survey for estimation of the prevalence of asthma, and prospective collection of resource utilization and quality-of-life data for 12 months, Phase B: comparison of healthcare resource usage collected prospectively to the data collected using administrative data in the population recruited in Phase A, and Phase C: Economic modeling of asthma to extrapolate the findings across Canada and into the future years.
The purpose of this study is to compare absorption of salmeterol and fluticasone from Salmeterol/fluticasone Easyhaler test products to the commercially available product Seretide Diskus
Asthma, abbreviation for bronchial asthma, is one of the common chronic airways disease that threatens human health. Typical symptoms of asthma are recurrent wheezing, shortness of breath, chest tightness and cough, usually occurring at night or early morning. However, there are still some patients with only persistent clinical manifestations of chest tightness. Concerned about this group of patients, we presented a subgroup of bronchial asthma, namely, chest tightness variant asthma (CTVA). This asthma subgroup usually lacks asthma-specific clinical features such as wheezing, shortness of breath, wheezing, and therefore often misdiagnosed for a long time. In order to further understand the clinical characteristics, pathogenesis, and prognosis of patients with CTVA, we conducted a national multicenter observation study to further understand CTVA. Finally, we plan to clarify whether CTVA is a relatively independent asthma phenotype. Meanwhile, reducing misdiagnosis and perform an appropriate treatment of CTVA.
Physical activity is mandatory to the optimal development and health of children. The presence of asthmatic manifestations may influence the comportment of children and its family toward exercise and practice of sports. There no scientific argument to advice a reduction of physical activity in asthmatic children, but previous studies showed that physical activity is reduced in asthmatic children. The aim of this observational study is to evaluate the existing factors leading to this reduction of physical activity in asthmatic children and their families.
The overall purpose of the study is to compare the patterns of neurocircuitry activation in severe asthmatics vs. mild to moderate and healthy controls. The Investigators hypothesize that neurocircuitry activation increases with asthma severity, producing different neurocircuitry patterns for severe asthmatics than those of mild to moderate asthmatics or non-asthmatics.
The investigators compared the effectiveness of pulmonary rehabilitation program on asthma control in patients with uncontrolled and partially controlled asthma.
A randomized, multicenter, double-blind, placebo- controlled parallel-group study to determine the efficacy and safety of QAW039, compared with placebo, when added to standard-of-care (SoC) asthma therapy in adult and adolescent (≥ 12 years) patients with uncontrolled asthma with respect to change from baseline in forced expiratory volume in 1 second (FEV1) at the end of 12 weeks of treatment.

The purpose of this study is to verify the effects of continuous positive airway pressure (CPAP) on exercise capacity of children and adolescents with severe therapy-resistant asthma (STRA). A randomized, controlled, crossover clinical trial will be conducted. We expect the use of CPAP to increase exercise capacity in children and adolescents with STRA.
