Active clinical trials for "Asthma"

The researchers propose to study the airways of asthmatics given TPI ASM8 for 14 days, and examine the protective effects on allergen-induced bronchoconstriction, hyperresponsiveness and airway inflammation.

The purpose of the this study is to evaluate the efficacy and safety of 2 actuations Symbicort®pMDI® 40/2.25 μg twice daily compared with1 inhalation Symbicort Turbuhaler® 80/4.5 μg twice daily and 1 inhalation Pulmicort®Turbuhaler® 100 μg twice daily for 6 weeks.

A single intravenous injection of zileuton (150 or 300 mg) will be administered to patients with stable asthma. The goals will be to determine if zileuton i.v. can produce a rapid increase in FEV1/PEFR and when this effect can be seen. The safety of this route of administration of zileuton will also be studied. PK will be obtained in a population based method.

Asthma is a common chronic disease characterized by airway inflammation and bronchoconstriction. This study utilizes the drug rosiglitazone (Avandia)to treat the effects of airway inflammation in patients with asthma. The study will be conducted on 14 adult steroid naive patients with asthma. Patients with qualifying pulmonary function testing values will be eligible for enrollment. Enrolled subjects will be treated with rosiglitazone orally at 2mg dose for 4 weeks. Patients will be reassessed and dosing will increase in 4 week increments up to 8mg.

The purpose of the study is to evaluate in subjects suffering from nocturnal asthma, the efficacy and safety of modified release Prednisone on signs and symptoms.

This is a clinical study that is designed to study the effects of the supplemental intake of enriched omega-3 polyunsaturated fatty acids (fish oil) in patients with moderate to severe asthma. Some asthmatics produce a large amount of inflammatory leukotriene proteins-proteins that contribute to wheezing and inflammation in the airway. Inhibiting the detrimental effects of leukotrienes is a key goal of controller therapy in severe asthmatics. Some asthmatic patients appear to have specific mutations of the arachidonate 5-lipoxygenase (ALOX5) gene, one gene that regulates the production of the inflammatory leukotrienes. Omega-3 fatty acids can interfere with the arachidonic acid pathway and decrease the production of leukotrienes, and this may benefit moderate and severe asthma patients. Our hypothesis is that omega-3 fatty acid supplements, added on to a patient's asthma medication regimen, can decrease the number of minor asthma exacerbations compared to patients who do not receive the supplement. Furthermore, we believe that asthma patients with specific ALOX5 gene mutations will benefit most. We will enroll 30 asthma subjects to take part in this trial. They will undergo genotyping of the ALOX5 gene and be treated with omega3-fatty acids (fish oil) and placebo over a nine month period. We expect that this strategy will allow us to discover which moderate and severe asthma patients will benefit most from supplements of omega-3 fatty acids. Treatment of chronic diseases, such as asthma, is a key mission of the Center of Health and Nutrition Research.

The purpose is to determine if: 1) Escitalopram treatment will be associated with less oral corticosteroid use than placebo in outpatients with severe asthma and moderate or severe major depressive disorder (MDD). 2) Escitalopram treatment will be associated with greater improvement in asthma symptoms than placebo in outpatients with severe asthma and moderate or severe MDD. 3) Escitalopram treatment will be associated with greater depressive symptom remission rates than placebo in outpatients with severe asthma and moderate or severe MDD.

The purpose of this study is to evaluate the tolerability and pharmacokinetics of three doses of MAP0010 (Unit Dose Budesonide) compared with Pulmicort Respules® (Budesonide) in healthy volunteers.

The trial is a randomised, double-blind, placebo-controlled, parallel-group trial to evaluate the efficacy and safety of 5 µg tiotropium over a 48-week treatment period as compared to placebo. Tiotropium inhalation solution delivered by the Respimat® inhaler will be examined as add-on controller therapy on top of usual care in patients with severe persistent asthma. The primary objective of each trial is to evaluate the long term efficacy of tiotropium over placebo on top of usual care in patients with severe persistent asthma as determined by pulmonary function testing, effects on asthma exacerbations, effects on quality of life, on asthma control and health care resource utilisation. The secondary objective of each trial is to compare the long term safety of tiotropium with placebo in this patient population.

This study enrolled 30 healthy volunteers and 30 patients with atopic asthma, for a total of 60 subjects. The study examined the tolerability of omalizumab and omalizumab excipients in two successive cohorts of subjects, healthy volunteers and patients with allergic asthma without prior exposure to omalizumab, according to a skin test protocol, consisting of a prick skin test and/or intradermal test.
