Active clinical trials for "Asthma"

The most commonly used drug for immediate relief of symptoms of asthma is the blue puffer, albuterol or salbutamol (Ventolin). Racemic albuterol is a mixture of two forms of albuterol which are mirror images of each other i.e. R-and S- isomers. The investigational treatments are R-albuterol and S-albuterol. R-albuterol ( levalbuterol) has been shown to have a slightly better bronchodilator effect as compared to the racemic albuterol and is well- tolerated in patients. However it is still not clear whether the S-isomer has no effect or has a harmful effect on the airways. The purpose of this study is to compare the effects of the R- and S- isomers on allergen induced airway inflammation in subjects with mild atopic asthma. This will give us a better idea as to whether the routine use of levalbuterol is superior to racemic albuterol.

The purpose of this study is to evaluate the long-term safety of the fixed combination asthma drug FlutiForm HFA MDI (containing fluticasone propionate and formoterol fumarate) in adult and adolescent patients with mild to moderate-severe asthma.

Primary objective: To demonstrate the efficacy of ciclesonide, compared to placebo, at 80 μg twice daily (BID) or 40 μg BID for 12 weeks in patients with persistent asthma. Secondary objective: To assess the safety and tolerability of ciclesonide.

This study will investigate whether study subjects with previously uncontrolled asthma treated with SERETIDE Diskus 50/250 CCI18781+GR33343 mcg twice a day can attain a level of Total Control of their condition and whether adherence to treatment can be enhanced by teaching the subjects. Two groups of equal size with identical medical treatment will be compared with each other, the test group receiving three training modules during study visits and the control group regular study visits only.

The purpose of this study was to determine whether antiepileptic drug phenytoin is effective in the treatment of chronic asthma in children.

A new formulation of Fluticasone propionate/Salmeterol comparing a lower dose of fluticasone propionate and salmeterol was compared with concurrent administration of fluticasone propionate and salmeterol. Administration occurred over 14 days and tolerability, PK (pharmacokinetic) and PD (pharmacodynamic) measurements were performed.

This was a multicenter, open label, randomized, controlled, safety trial in subjects aged 6-75 years with a diagnosis of moderate to severe, persistent asthma. A total of 1899 subjects were randomized (2:1) to either the active treatment group or the control group. Upon successful completion of the screening period (~2 weeks), each subject entered the 24 week study.

Breathing retraining supervised by a physiotherapist will result in improvements in the quality of life and asthma control of patients treated for asthma in the community with symptoms suggestive of dysfunctional breathing. To investigate the effects of breathing retraining on clinical and physiological parameters of asthma control, to identify the characteristics of patients who benefit, to perform a health economic evaluation.

This 8 arm study will evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of single ascending doses of R1671 or placebo in patients with mild, intermittent, asymptomatic asthma. Patients will be randomized to receive placebo or R1671, at a starting dose of 0.0015mg, by intravenous infusion; this dose will be escalated in subsequent groups of patients after a satisfactory assessment of the data from the previous dose. The anticipated time on study treatment is <3 months, and the target sample size is <100 individuals.

The purpose of this study is to confirm the dose of roflumilast to be used for asthma management by comparing the effects of 250 mcg and 500 mcg oral roflumilast with placebo on pulmonary function and asthma symptoms.
