Filter by:To evaluate whether beclomethasone dipropionate / formoterol (BDP/FOR; Fostair® 100/6) is at least equivalent in terms of exacerbation prevention to fluticasone dipropionate / salmeterol (FP/SAL; Seretide® 125) in matched asthma patients switching to BDP/FOR following treatment with FP/SAL in normal clinical practice compared with patients not switched.
The objective of this study is to assess the efficacy and safety of SOTB07 in asthma patients by observing changes FEV1 (% predicted) as the primary efficacy endpoint after oral administration of SOTB07 200mg, 400mg, placebo for 12 weeks.
To examine whether a breathing test (methacholine challenge using impulse oscillometry) can be used to tell the difference between two different doses of an inhaled drug, salmeterol, delivered by Advair in children with asthma
The purpose of this study is to determine if brodalumab (AMG 827) is safe and effective compared to placebo as measured by change in Asthma Control Questionnaire (ACQ) composite scores.
This is a multicenter, randomized, double-blind, double-dummy, placebo-controlled, single-dose, 5-treatment, 5-period, 5-way crossover study in pediatric patients with persistent asthma. The primary purpose of this study is to compare the efficacy and safety of Albuterol Spiromax with that of ProAir HFA in pediatric asthma patients at 2 delivered dose levels equivalent to 90 mcg and 180 mcg of albuterol base.
The long-range goal of this protocol is to more completely understand the risks and the pathophysiology of asthma exacerbations, in order to develop prevention strategies and/or expedite a return to complete control of baseline asthma symptoms.
Our central hypothesis is that dietary limitations introduced by food allergy will contribute to increased food insecurity in households with food allergic children when compared to food insecure households without food allergic children.
This study examined whether the Pediatric Asthma Control and Communication Instrument for the Emergency Department (PACCI-ED), a 12-item questionnaire, can help doctors in the emergency department accurately assess a child's asthma control. This study involved an intervention with the doctors in the emergency department of an urban pediatric hospital. The intervention was done when one of the doctors involved in the study treated a child aged 1-17 years for an asthma exacerbation. Parents answered questions on the PACCI-ED about their children's asthma. Half of the doctors were allowed to see the PACCI-ED results and half were not. The two groups of doctors were compared on their ability to correctly identify asthma control categories, whether a child's asthma was worsening or improving, whether the family was administering controller medications as often as they should, and how much burden the child's asthma was for the family.
The mainstay of asthma treatment is with inhaled steroids (commonly called a 'preventer') to keep the symptoms of asthma under control. Increasing strengths of steroid inhaler may be required in order to gain control of asthma, and this is usually guided both by symptoms and simple measurements of lung function such as peak flow. The airways (breathing tubes) in the lungs get smaller the further into the lungs they go. Most simple measurements of lung function only reflect the larger 'central' airways and don't provide information on the smaller 'peripheral' airways.Newer measurements have been developed that can now give us accurate information on how the smaller airways are working.Indeed the small airways seem to play a significant role in asthma in terms of inflammation and airway narrowing. Recently, new types of steroid inhalers have been developed that have a much smaller particle size than other standard inhaled steroids.These have been shown to go deeper into the lungs, thus getting into the smaller airways. There have been a few studies suggesting that this might improve asthma control. However, we do not know if when small airway function is shown to be abnormal, whether this improves with extra-fine particle inhaled steroids, nor whether by improving small airway function specifically this translates into improved asthma control. In this study we wish to study asthmatic patients who are not completely controlled on standard particle size inhaled steroids, in addition to having evidence of abnormal small airway function. By doing this we want to find out whether changing to the same dose of an extra-fine particle inhaled steroid instead will improve asthma control by getting deeper into the lungs and improving small airway function.

Recently, new types of inhaler formulations have been developed that have a much smaller particle size than other standard formulations. These formulations have been shown to go further into the lungs, thus getting into the smaller airways. In this study we aim to compare the two extremes of available long acting beta agonists in terms of particle size i.e. extra fine formoterol (Atimos) versus coarse particle salmeterol (Serevent)in asthmatics with abnormal small airway function using a breathing test called impulse oscillometry. By using this test we will be able to find out whether using an extrafine particle inhaler improves small airway function.
