Active clinical trials for "Asthma, Exercise-Induced"

The purpose of this study is to investigate the micro ribonucleic acid (mRNA) profiles of patients with EIA without allergic sensitization and EIA with house dust mite sensitization compared to that of healthy controls.

The investigators recently observed airway inflammation and increased damage-associated molecular pattern (DAMP) level in sputum of children (age 11-12y) and adolescents (18-23y) from elite sport programs in Belgium with increased risk of bronchoconstriction upon extreme exercise. They here want to validate these findings in a cohort 13-18y.

Researchers found that impairments in the cardiopulmonary system caused by acute exposure to ozone were outweighed by repeated exposures to ozone. The goal of this study is to confirm there will be an adaptation similar to what was previously proved but in individuals with asthma and exercise-induced bronchoconstriction (EIB). The purpose is to examine adaptive responses in a randomized cross-over trial in which physically active individuals will perform submaximal exercise on five days in ozone and filtered air exposures separated by a washout period.

The primary objective of this study is to assess if the unstandardized field exercise challenge test (ECT) using AsthmaTuner can be performed independently by youths that have been investigated for asthma. This is an open feasibility study including youths who have been investigated for asthma. Participants will be equipped with a digital spirometer and mobile phone app to perform an exercise tests in their natural training environment. Feasibility will be evaluated using questionnaires.

The Swiss Paediatric Airway Cohort (SPAC) is a national, prospective clinical cohort of children and adolescents who visit physicians in Switzerland for recurrent wheeze, cough, and exercise- or sleep-related respiratory problems. SPAC aims to answer important questions on clinical phenotypes, prognosis, diagnosis and treatment. SPAC is part of routine care, and only clinically indicated investigations are done. The comprehensive baseline assessment includes a detailed questionnaire to families, plus test results, diagnoses and treatments from hospital records. Follow-up is via monthly questionnaires the first 12 months and thereafter annual questionnaires to families, and data from follow-up visits. Currently, 4344 patients from 10 clinics and hospitals in Switzerland (Aarau, Basel, Bern, Chur, Horgen, Lausanne, Luzern, St. Gallen, Worb, Zurich) have been enrolled. SPAC provides real-life data on children visiting the Swiss health care system for common respiratory problems. It will provide a research platform for health services research, and for nested clinical and transitional studies.

The purpose of this study is to find out if Symbicort® (budesonide/formoterol), a new combination asthma medication, is more effective than budesonide alone in controlling exercise induced asthma. The investigators hypothesize that in children and adults who suffer from asthma and exercise induced asthma there will be less decline in lung function associated with exercise when they receive the study medication.

The primary objective of this study is: To evaluate the magnitude of the protective effect of the combination of budesonide and formoterol on an as-needed basis compared to the use of terbutaline as-needed on exercise induced bronchoconstriction in adults and adolescents with mild intermittent asthma The secondary objectives of this study are: To evaluate the magnitude of the protective effect of the combination of budesonide and formoterol as-needed compared to regular once daily use of budesonide plus terbutaline as-needed on exercise induced bronchoconstriction in adults and adolescents with mild intermittent asthma To evaluate safety of budesonide/formoterol as-needed, terbutaline as-needed and regular use of budesonide + terbutaline as-needed as terms of adverse event

The purpose of this study is to determine the effect of four weeks of treatment with two investigational drugs (oral versus inhaled administration) plus an inhaled medication in the treatment of airway constriction brought on by exercise in participants with asthma.

This study was designed to examine the effectiveness of two bronchodilator inhalers in patients who have exercise-induced asthma.

This is a multicenter, randomized, double-blind, single-dose, placebo-controlled, 2-period, crossover study to evaluate the efficacy and safety of budesonide/albuterol metered-dose inhaler (BDA MDI/PT027) as compared with a placebo metered-dose inhaler (placebo MDI) on exercise-induced bronchoconstriction (EIB) in adult and adolescent subjects with asthma. Subjects will receive each study treatment on separate visits and undergo a treadmill exercise challenge test for up to 10 minutes so that the effect of study treatment on exercise-induced bronchoconstriction can be evaluated.
