Active clinical trials for "Asthma"

The purpose of this study is to determine whether food concentrates supplementation (vegetable plus fruit, fish, probiotics) are effective to alleviate drug used, asthma symptoms and lung function in children due to asthma.

This study will evaluate the safety, tolerability, and pharmacokinetics (PK) of multiple dose treatment with MK-1029 in adults with mild to moderate persistent asthma.

Low-income, minority children are disproportionately affected by asthma and can experience higher rates of asthma attacks, lower lung function, decreased physical activity, increases in school absenteeism, and higher rates of death. The National Center for Children in Poverty suggests that effective interventions to improve asthma and reduce harm for high risk groups (like low-income minority children) must begin in early childhood. Previous research has shown that asthma education programs can be effective to improve overall asthma management in preschool children, but there has been limited sustainability of these programs in medical, educational, and social environments that serve young high risk children. One of the core missions of federally-funded Head Start programs is to provide preventive health services and screening to their low-income preschool students and would be an ideal setting in the community to disseminate an early asthma education program. The purpose of this study is to draw on our health and research partnership with Baltimore City Head Start programs to test the effectiveness of a home-based asthma education intervention combined with a Head Start level asthma education program compared to a Head Start level asthma education program alone.

Current asthma medicines include inhalers. A common type of inhaler is called a 'beta-agonist' (e.g. salbutamol). They improve asthma symptoms by stimulating areas in the airway causing it to widen. Although these drugs are useful short term, long term use can make asthma worse in some people. 'Beta-blockers' are the complete opposite type of medication. Just now they are avoided in patients with asthma. Beta-blockers cause problems in asthmatics in the short term, including severe asthma attacks. The other mainstay of inhaler treatment for asthma is inhaled steroid or 'preventer' medication. These work by dampening down the inflammation in the lungs that occurs in asthma. New research has suggested that longer term use of beta-blockers can also reduce airway inflammation which may improve asthma control. This research was done in asthmatic patients who didn't need inhaled steroids to control their asthma. At the moment the investigators are studying to see if there is a benefit of beta-blocker use for asthma over and above asthmatics own usual doses of inhaled steroids. In this study, the investigators will be trying to find out if adding a beta blocker to a smaller dose of steroid inhaler has the same effect on asthma control as just using a higher dose of steroid inhaler by itself.

Acute asthma is the most common cause of pediatric hospitalizations. While the investigators know that repeat inhalations of ß2 agonists and ipratropium with early oral steroids substantially reduce hospitalizations, many children are resistant to this standard initial therapy. About a third of children remaining in moderate to severe distress after standard therapy are admitted to hospital and comprise 84% of pediatric acute asthma hospitalizations. Finding safe, non-invasive, and effective strategies to treat children resistant to standard therapy would substantially decrease hospitalizations resulting in considerable health care savings and reduction of the psycho-social burden of the disease. While studies of magnesium sulfate (Mg) given intravenously (IV) suggest that this agent can reduce hospitalizations in both adults and children resistant to standard initial therapy Nebulization is an alternate route for administering Mg. This route has the advantage of being non-invasive and is likely much safer due to lower systemic delivery. Direct delivery via nebulization allows higher Mg concentrations at the target site, the lower airways, with a smaller total drug dose. The investigators propose to conduct a properly designed study to clarify the role of nebulized Mg.

The aim of this trial is to evaluate the efficacy and safety of 2.5 and 5 mcg tiotropium compared to placebo over 12 week treatment period. Tiotropium inhalation solution will be delivered via Respimat inhaler and will be examined on top of maintenance inhaled corticosteroid treatment in patients with mild persistent asthma. Efficacy and safety will be assessed by measuring the effects on lung functions, effects on lung exacerbations, effects on asthma control and numbers of adverse events.

Rationale for the current trial is to evaluate the efficacy and safety of three doses (1.25 µg, 2.5 µg and 5.0 µg ex mouthpiece) of tiotropium inhalation solution in patients with moderate persistent asthma who are still symptomatic despite regular maintenance therapy with inhaled corticosteroids (ICS). The data collected in the present trial will provide useful information to health care providers and patients regarding the efficacy and safety of a once daily inhalation of three different doses of tiotropium solution delivered by the Respimat® inhaler in addition to inhaled corticosteroids in the treatment of not fully controlled moderate asthma in comparison to placebo. The Pharmacokinetics (PK) of tiotropium is well established in COPD patients. However, there is currently no PK data available for the 3 doses of tiotropium being tested in this trial in patients with moderate persistent asthma. Tiotropium is a once daily drug. Hence, the rationale for blood and urine sampling for PK analysis over 24 hours in a subset of patients is to confirm the PK of the 3 doses in moderate asthma patients. Rationale for the 24-hour pulmonary function test sub-investigation is to demonstrate that a once daily dosing of tiotropium inhalation solution is effective and safe in the treatment of moderate persistent asthma.

The purpose of this study is to demonstrate that the CHF 1535 (fixed combination of Beclometasone Dipropionate (BDP) 100 µg / Formoterol Fumarate (FF) 6 µg) delivered via the NEXT Dry Powder Inhaler (DPI) does not show a greater exposure to BDP, Beclometasone-17-Monopropionate(B17MP, active metabolite of BDP) and FF in comparison to a free combination of BDP DPI plus FF DPI licensed products after a morning dose administration of BDP and FF (total dose of BDP 400 µg / FF 24 µg) in adolescent and adult asthmatic patients.

To evaluate the efficacy, dose response and safety of four doses of GSK2190915 in tablet form (10mg, 30mg, 100mg and 300mg) administered once daily, over 8 weeks compared with placebo in adolescent and adult subjects (12 years of age and older) with persistent asthma. These data will form the basis for the selection of the optimal daily dose of GSK2190915 to be carried forward in Phase III asthma studies. The study also includes Fluticasone Propionate Inhalation Powder (100 mcg, twice daily) and Montelukast (10mg, once daily) to allow for an exploratory analysis of the efficacy of GSK2190915 versus a low dose inhaled corticosteroid and a leukotriene receptor antagonist.

This Phase II, double-blind, placebo-controlled, randomized, parallel-group study is designed to evaluate the efficacy, safety and tolerability of MEMP1972A when administered to patients by intravenous (IV) infusion for the treatment of allergen-induced asthma.
