Active clinical trials for "Asthma"

The purpose of this study is to determine the effect of an approved medication on the symptoms of seasonal allergic rhinitis (a seasonal variety of inflammation of the mucous membrane of the nose) in patients who are experiencing symptoms of seasonal allergic rhinitis and asthma.

The primary objective of this study is to compare the QVAR-Easi-Breathe 100 mcg/day and QVAR-Easi-Breathe 200 mcg/day with placebo relative to changes in forced expiratory volume in 1 second (FEV1) results following 12 weeks of treatment. Secondary objectives such as daily asthma symptoms scores (per week), morning peak expiratory flow (PEF) values, nocturnal awakening and utilization of rescue medication per day also will be evaluated. In addition, an exploratory evaluation will assess the comparability of the two devices (i.e., QVAR-Easi-Breathe versus QVAR-MDI) at the same dose levels.

The purpose of ICAC-01 is to determine whether an asthma treatment strategy that measures exhaled nitric oxide (eNO) to indicate disease progression is more effective in treating asthma symptoms when combined with existing asthma treatment guidelines than treatment using the guidelines alone.

Asthma currently affects an estimated 15 million Americans. A number of studies have found an association between low dietary magnesium (Mg) intake and increased asthma incidence and severity of symptoms. However, clinical intervention trials are necessary to directly assess whether there is a true protective or preventative causal relationship between low Mg and asthma. In our study, we will assess the effects of 6 1/2 months of oral Mg supplements or placebo on clinical markers of asthma control, indirect biomarkers of inflammation, bronchial hyperresponsiveness, and indices of oxidative defense and damage in subjects with mild to moderate persistent asthma.

A One Year Clinical Trial Assessing the Usefulness and Safety of Inhaled Insulin in Diabetics with Asthma

Asthmatic smokers display a blunted response to both inhaled and oral corticosteroid treatments and are at increased risk for exacerbations and near fatal asthma. The prevalence of smoking in asthmatics runs between 20-30%. Therefore, new, more efficacious treatments are required. Recent work has demonstrated a mechanism which may explain steroid resistance. A commonly used drug called theophylline can reverse this steroid resistance in laboratory studies. Another commonly used drug, rosiglitazone can reverse smoking induced lung inflammation in laboratory studies. The investigators aim to study the effects of these drugs on smoking asthmatics' lung function and other parameters including quality of life and asthma control.

A substance called immunoglobulin E (IgE), which is naturally produced by our body, has a key role in generating asthma attacks. In patients with allergies, there is an exaggerated production of IgE in response to specific substances such as pollens. Omalizumab is a new drug that inactivates IgE. This study tested the safety and efficacy of omalizumab against asthma attacks in children with allergic asthma.

The primary purpose of this study was to investigate the efficacy of levalbuterol compared to a placebo and compared to albuterol in the treatment and prevention of bronchoconstriction in adolescent and adult subjects with asthma, with all treatments administered 4 times a day (QID).

The primary objective of this study is to investigate the efficacy of levalbuterol 90 ug (2 actuations, 45 ug each) versus placebo (2 actuations) in the treatment and prevention of bronchoconstriction in adolescent and adult subjects with asthma, with all treatments administered 4 times a day (QID).

This study was designed to examine the effectiveness of a breath-operated albuterol inhaler in asthma patients who have difficulty using their standard "press-and-breathe" inhaler.
