Active clinical trials for "Asthma"

This study is designed to compare the effectiveness and safety of Fluticasone Furoate/Vilanterol Inhalation Powder (100mcg Fluticasone Furoate ((FF), GW685698)/25mcg Vilanterol ((VI), GW642444) or 200mcg Fluticasone Furoate ((FF), GW685698)/25mcg Vilanterol ((VI), GW642444) ) delivered once daily via a Novel Dry Powder Inhaler (NDPI) compared with the existing asthma maintenance therapy over twelve months in subjects diagnosed with asthma. This is a Phase III multi-centre, randomised open label study. Subjects who meet the eligibility criteria are randomised and will enter a 12 month treatment period.

The purpose is to Evaluate the Efficacy, Safety, and Tolerability of 3 Different Doses of AZD5069 Twice Daily as Add-on Treatment to Medium to High Dose Inhaled Corticosteroids (ICS) and Long-acting β2 Agonists (LABA), in Patients with Uncontrolled Persistent Asthma

Background: In recent years, the prevalence of both asthma and obesity has risen dramatically among children and adolescents in the United States. Given the concurrent rise in the two epidemics, there may be an underlying link. Obesity contributes to asthma severity and control, and may play a role in its underlying cause. Obesity is associated with a state of heightened inflammation that may lead to an increase asthma symptoms and severity. Obese adult patients treated with montelukast, an anti-inflammatory agent, seemed to have better asthma control than those treated with other standard asthma medications. The use of montelukast in obese children and adolescents has not been specifically studied. Hypotheses and Specific Aims: The use of montelukast will improve asthma symptoms and objective markers of asthma to a greater degree in obese, as opposed to non-obese children and adolescents. The investigators would like to determine if the use of montelukast will improve objective asthma scores, pulmonary function, markers of inflammation and medication use to a greater degree in obese as opposed to non-obese children/adolescents. Potential Impact: Given the growing epidemic of obesity-associated asthma in the U.S., a tailored approach focused on obese asthmatic children may help reduce the burden of this disease, health care costs and potential long-term complications as these children enter adulthood. Furthermore, this study may help clarify the underlying mechanisms that link asthma and obesity. Although this proposal is focused on one medication, it provides an example of how certain medications may have differential efficacy in the obese asthmatic.

Propeller Health is collaborating with Dignity Health (formerly Catholic Healthcare West (CHW)) to carry out a focused demonstration project to evaluate the effectiveness and potential cost savings of a deployment of the Propeller Health approach to asthma management. The Propeller Health goal is to bring together the best technology and asthma insight in order to provide Dignity Health with an engaging, data-driven chronic care program to improve asthma management and lower healthcare utilization costs, and to respond to prevention-focused reforms to health insurance laws. This project has been designed to implement and evaluate a data-driven program to improve asthma management and control and lower direct costs through reductions in healthcare utilization. This program has been developed by Propeller Health and has gone through preliminary testing. Each subject participating in the study will receive an Propeller Health device, which captures the time and location of use of inhaled short-acting bronchodilators over a twelve-month period. This information is processed and delivered at regular intervals to the patient and his or her provider to support improved asthma management.

The aim of this trial is to evaluate the safety and efficacy of 2.5 and 5 µg tiotropium over a 52-week treatment period as compared to placebo. Tiotropium inhalation solution delivered by the Respimat inhaler will be examined on top of maintenance treatment with inhaled corticosteroid controller medication in patients with moderate to severe persistent asthma. Efficacy and safety will be assessed by measuring effects on lung function, effects on asthma exacerbations, effects on asthma control, and number of adverse events.

Primary Objective: To investigate the effects of Dupilumab (SAR231893/REGN668) administered subcutaneously (SC) once weekly (qw) for 12 weeks as compared to placebo on reducing the incidence of asthma exacerbation in participants with persistent moderate to severe eosinophilic asthma. Secondary Objectives: To assess the safety and tolerability of Dupilumab administered SC qw for 12 weeks in participants with persistent moderate to severe eosinophilic asthma. To assess Dupilumab serum concentrations following qw SC dosing for 12 weeks in participants with persistent moderate to severe eosinophilic asthma.

This study will compare efficacy and safety of different regimens of olodaterol administration in asthma (once daily, twice daily) with placebo in a complete cross-over design each within one of the two daily dose groups (medium or high daily dose).

Cysteinyl leukotrienes (cys-LTs) are lipid inflammatory mediators that abound in mucosal inflammation and play a validated role in the pathogenesis of human asthma. It has recently been demonstrated that the platelet adenosine diphosphate (ADP) receptor, P2Y12, is required for LT4-mediated pulmonary inflammation and could be a novel potential therapeutic target for asthma. Thienopyridines (such as ticlopidine and clopidogrel) are pro-drugs, with proven antithrombotic efficacy, whose active metabolites selectively inhibit the platelet P2Y12 receptors. One of the drawbacks of thienopyridines is the high inter-individual variability in pharmacological response, mostly due to the high inter-individual variability in the capacity of transforming the pro-drug in its active metabolite. Prasugrel is a new member of the class of thienopyridines, with faster onset of action and a more uniform inhibition of platelet function compared to the other thienopyridines. Primary objective of our study will be to test whether or not the inhibition of the platelet P2Y12 receptor by prasugrel reduces the bronchial hyper-reactivity in patients with chronic asthma. The investigators designed a randomized, double blind (Subject, Caregiver, Investigator, Outcomes Assessor), crossover, placebo-controlled, prospective study, which will enroll 26 patients. Randomization will be performed in sequential blocks. Patients will be blindly and randomly allocated to treatment A (prasugrel 10 mg daily) or B (placebo) for 15 days. After a 15-day wash-out period, patients who had initially been allocated to treatment "A" will be allocated to treatment "B", and vice versa. Measurements will be done at baseline and on day 15 after each treatment, at the same time (+/- 1 h) of the day. Primary efficacy measure will be changes in airway hyper-responsiveness, recorded as reduction of FEV1 using the mannitol test induction. Secondary efficacy measures will be changes in markers of airway inflammation in sputum, changes in measurement of nitric oxide expiration (as surrogate marker of airway lung inflammation), count of eosinophil granulocytes in peripheral blood smear, changes in asthma exacerbation rates and symptom scores. Changes in phosphorylation of platelet VASP (Vasodilator-stimulated phosphoprotein) by ADP, measured with a flow cytometric technique, will be used as markers of the degree of inhibition of platelet P2Y12 receptors attained in each subjects by treatment with prasugrel.

This clinical study evaluates the 12-week efficacy and safety of Epinephrine HFA Inhalation Aerosol HFA the proposed HFA formulation of metered dose inhaler (MDI) of Epinephrine, in comparison to a Placebo-HFA control MDI and the currently marketed Primatene® Mist (epinephrine CFC inhaler), in adolescent and adult subjects with asthma.

To evaluate efficacy and tolerability of specific subcutaneous immunotherapy with a cocktail of recombinant major allergens of Timothy Grass Pollen (Phleum pratense) in subjects with rhinoconjunctivitis caused by grass pollen with/without controlled asthma.
