Active clinical trials for "Asthma"

Up to 40% of patients with asthma have allergic rhinitis and treatment of nasal airway inflammation with topical steroids improves the twitchiness of the airways (hyperresponsiveness) and overall asthma control. The use of inhaled corticosteroids reduces symptoms, severity of asthma attacks, improves quality of life, and reduces asthma related deaths. Similarly, treatment of rhinitis with nasal steroids reduces symptoms and improves quality of life. While there is evidence that combined treatment of the nose and the lungs with topical steroids improves symptoms and underlying inflammation, it is unclear whether such control can be achieved using a smaller dose of inhaled steroid in combination with nasal steroid. It is therefore the intention of this study to evaluate if combination steroid therapy (nose and lungs) has a steroid sparing effect in patients with asthma and rhinitis using sensitive markers of airway inflammation.

To assess the efficacy of inhaled AIR645 in the suppression of the Asthmatic Responses in subjects with mild asthma inhaling an allergen.

Asthma self-management is an effective way to improve the outcomes of patients with asthma. However, to be most effective these interventions should be targeted and designed toward a specific population or group. There is currently no asthma self-management intervention directed towards older adults. The hypothesis is that a 6-session asthma self-management intervention will improve the outcomes of older patients with asthma.

Extracorporeal leukocytapheresis (LCAP) or granulocytapheresis (GCAP) has been used in the treatment of patients with rheumatoid arthritis and ulcerative colitis and has shown promising safety and efficacy. LCAP and GCAP seem to be effective for steroid-resistant inflammation. The investigators have already reported safety and efficacy of GCAP in refractory asthma and expect the beneficial effect of LCAP in refractory asthma. In this study, in order to improve the therapeutic effect of LCAP by increasing the quantity of leukocytes that were removed, the investigators conducted a clinical study to investigate safety and efficacy of high-dose LCAP performed using a larger filter and an increased dose of the blood volume per body weight treated, as an possible therapy for refractory asthma.

This will be a double blind, randomised, 4 arm, parallel group, placebo controlled study of three dose levels of OC000459 tablets in patients with asthma controlled by beta agonist drugs alone. This study will compare the patients on OC000459 at three different dose levels (25mg once daily, 100mg twice daily and 200mg once daily) with patients on placebo after dosing for 17 weeks. The trial will be undertaken in an outpatient population. Each treatment arm will consist of at least 110 subjects. The objective is to assess the efficacy of these dose levels on the patients asthma.

This study will investigate the additive effect of montelukast (MK0476) taken along with inhaled beclomethasone versus inhaled beclomethasone alone.

The objective of this study is to evaluate the effect of the combination of formoterol and beclometasone dipropionate on central and peripheral airway dimensions in asthmatic patients using Computational Fluid Dynamics (CFD). Further more, the effect of this combination therapy on exhaled NO, lung function (spirometry, body plethysmography, diffusion and resistance) and subjective asthma control score as well as the safety of this combination will be assessed.

This study assessed the efficacy, safety, tolerability, and pharmacokinetics of two different formulations of indacaterol, one administered via the Concept1 device and one administered via the Simoon device. The study aimed to determine whether the novel formulation (Simoon) had a similar profile to that of the established formulation (Concept1).

This study will evaluate the effect of omalizumab on markers of impairment in patients with inadequately controlled persistent allergic asthma on Step 4 or above therapy as defined in the 2007 National Heart, Lung, and Blood Institute (NHBLI) Guidelines

To investigate the Efficacy and Safety of Levalbuterol versus Racemic Albuterol in the Treatment of Acute Asthma.
