Active clinical trials for "Asthma"

The aim of the study is to compare the effects of oral roflumilast with placebo on lung function in patients with asthma.

The purpose of this research study is to examine the effectiveness of a parent-youth teamwork treatment and an asthma education treatment in helping children use their asthma medicines correctly. We also want to learn about how these treatments affect parental involvement in asthma care, parent and youth relationships, and children's health care.

The purpose of this study is to investigate the efficacy and safety of fexofenadine 120mg BID compared to placebo in the treatment of subjects with mild to moderate persistent asthma

The purpose of this study is to determine the effect of omalizumab, compared to placebo, on clinically significant asthma exacerbation rates in adolescents and adults with asthma.

The purpose of this study is to evaluate the safety of levalbuterol as compared to racemic albuterol based on the frequencies of adverse events reporting during a 12-month period of chronic dosing of adolescent and adult subjects with asthma.

The purpose of this study is to determine if subjects with symptomatic asthma who are assigned to treatment with a proton pump inhibitor (PPI) drug such as Nexium have fewer asthma attacks than similar subjects assigned to placebo treatment.

This is a study investigating whether 14 days of dosing with GW274150 has a beneficial effect on a model of asthma type inflammation called the allergen-induced late asthmatic response. This will be compared with the response after treatment with a dummy (placebo) and a tablet treatment for asthma called Singulair (montelukast). Subjects in the study will receive all 3 treatments in a random order. The study is double-blind so subjects will not know which treatment they are taking at any given time.

The purpose of the study is to compare the efficacy of a flexible dose of Symbicort (budesonide/formoterol) with conventional stepwise best standard treatment in patients with persistent asthma.

This study will determine if airway antioxidant levels in allergic asthmatics are enhanced with a combination of vitamin E and vitamin C therapy.
