Trial ID	Title	Status	Sponsor	Phase	Start Date	Summary
NCT00117182 ↗	Aridol Challenge as a Tool to Predict Treatment Response to Inhaled Corticosteroids in COPD	Completed	Pharmaxis	Phase 2	2005-07-01	The purpose of this study is to determine whether the Aridol (mannitol) challenge test can predict response to treatment with inhaled corticosteroids in COPD subjects. Subjects will undergo an Aridol test and then 3 months of treatment with inhaled corticosteroids. The effect on lung function and quality of life will then be measured and correlated with the Aridol test result.
NCT00252291 ↗	Ability of Aridol to Detect Bronchial Hyperresponsiveness in Suspected Asthmatics	Completed	Pharmaxis	Phase 3	2005-11-01	This is a Phase 3 study to determine the sensitivity and specificity of the Aridol bronchial challenge test to detect bronchial hyperresponsiveness in patients with suspected asthma. Patients with suspected asthma of either gender, aged between 6 and 50 years, with only mildly impaired lung function (FEV1 >70%) are to be tested with three different bronchial hyperresponsiveness challenges (Aridol, exercise and methacholine), and the results compared. A clinical diagnosis will also be made at the end of the study.
NCT01064245 ↗	Physiology of Cough in Asthma: Comparison of Sensory-Mechanical Responses to Mannitol and Methacholine Challenge Tests	Active, not recruiting	Queen's University (William M Spear / Start Memorial Fund)	N/A	2010-02-01	Cough is a common, disruptive and at times disabling symptom which often prompts patients to seek medical attention. Determining the cause(s) of chronic cough can be challenging, and costly. Asthma and other airway disorders are among the most common causes of chronic cough; and cough can be the sole symptom of asthma. Little is known about why some patients with asthma primarily cough and do not develop the other symptoms of asthma such as shortness of breath or wheeze. Improved understanding of the reasons for these different manifestations may lead to new and more effective treatment strategies. We have notices differences in pressure measurements inside the chest in patients who mostly cough during induced bronchoconstriction, which might be part of the explanation for varying symptoms. This study will compare lung mechanical responses during methacholine and mannitol-induced induced airway narrowing between typical asthma, cough variant asthma (CVA) and an airway inflammatory disorder that is not asthma.The purpose of this research is to explore the pathophysiology and sensory-mechanics of cough in individuals with asthma, CVA and methacholine-induced cough but normal airway sensitivity using mannitol and high-dose methacholine bronchoprovocation testing.
