NCT ID: NCT01340209 Completed - Asthma Clinical Trials

Evaluation of Tiotropium 2.5 and 5 µg Once Daily Delivered Via the Respimat Inhaler Compared to Placebo in Patient With Moderate to Severe Persistent Asthma

Start date: April 2011
Phase: Phase 3
Study type: Interventional

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.

NCT ID: NCT01340118 Completed - Asthma Clinical Trials

Improvement of FeNO and FEF25-75 After Inhaled Corticosteroid Treatment of Asthma

Start date: May 2010
Phase: Phase 4
Study type: Interventional

Abnormal lung function and high exhaled nitric oxide (FeNO) have been reported in asymptomatic patients with asthma. The investigators aimed to assess whether FeNO and FEF25-75 improve concurrently after treatment with inhaled corticosteroid (ICS) in patients with controlled asthma. Geometric mean (GM) FeNO and spirometric values in patients 8 to 16 years of age who maintained asthma control without controller medication were compared with healthy controls and patients with uncontrolled asthma who were also not receiving controller medications. Patients with controlled asthma and high FeNO (> 25 ppb) were randomized to ICS treatment or to remain untreated. Changes in spirometric values and GM FeNO from baseline were evaluated after 6 weeks.

NCT ID: NCT01338311 Completed - Asthma Clinical Trials

Salbutamol Tolerance Onset

Start date: March 2011
Phase: Phase 4
Study type: Interventional

Overuse of inhaled bronchodilator beta agonist medication results in a loss of effectiveness (i.e. tolerance). This has been shown for the short acting beta agonist salbutamol and the long acting beta agonist salmeterol. Tolerance to salmeterol is present within 24 hours. The onset of tolerance to salbutamol is not known.

NCT ID: NCT01334853 Completed - Asthma Clinical Trials

A Study to Assess Selected Biomarkers in Subjects Requiring Daily Inhaled Corticosteroids for Persistent Asthma

Start date: January 2011
Phase: N/A
Study type: Observational

The rationale for conducting this study is to explore potential clinical and peripheral biomarkers in subjects requiring daily medium to high dose inhaled corticosteroids for persistent asthma

NCT ID: NCT01333800 Completed - Asthma Clinical Trials

Cost-effectiveness Study of Beclomethasone Versus Ciclesonide as Controller Medications in Pediatric Asthma

Start date: July 2010
Phase: Phase 4
Study type: Interventional

The Objective was to Develop a Cost-Effectiveness study that compares Ciclesonide and Beclomethasone in pediatric asthma control.

NCT ID: NCT01332422 Completed - Asthma Clinical Trials

Special Drug Use Investigation for ADOAIR Metered-dose Inhaler (Pediatric)

Start date: November 2009
Phase: N/A
Study type: Observational

To investigate possible problems or questions in safety and efficacy of ADOAIR 100 DISKUS and ADOAIR 50 AEROSOL 120 in Japanese pediatric patients with bronchial asthma for a long term under the practical use conditions. In this special drug use investigation, the following items shall be handled as the priority investigation items for information collection. 1. Systemic effects accompanying steroid administration; influences on adrenocortical function, influences on bone metabolisms (fracture, osteoporosis, etc.), cataract, glaucoma 2. Events related to nervous system, musculoskeletal system and circulatory system; tremor, headache, cramp, tachycardia, etc.

NCT ID: NCT01332357 Completed - Asthma Clinical Trials

Use of Fluticasone Propionate/Salmeterol Combination Post Emergency Department Visit

Start date: June 2009
Phase: N/A
Study type: Observational

The objective of this study is to compare readmission to the emergency department for asthma in asthma patients who receive treatment with fluticasone propionate and salmeterol oral inhaler after an initial emergency department visit using a retrospective observational cohort study design.

NCT ID: NCT01332344 Completed - Asthma Clinical Trials

Outcomes in Patients Taking Fluticasone Propionate/Salmeterol Combination or Other Inhaled Corticosteroids

Start date: June 2009
Phase: N/A
Study type: Observational

The objective of this study is to compare healthcare utilization and costs in asthma patients who receive fluticasone propionate/salmeterol combination 100mcg/50mcg ("FSC 100/50") or inhaled corticosteriods in typical clinical practice using a retrospective observational cohort study design of large managed care database.

NCT ID: NCT01332292 Completed - Asthma Clinical Trials

Pharmacokinetics and PharmacoDynamics of GW685698 in Paedeatric Asthmatic Patients

Start date: May 2010
Phase: Phase 2
Study type: Interventional

This study will investigate the effect of dosing with flutucasone furoate in asthmatic subjects aged 5-11 years of age. A randomized, two-way crossover, with placebo control, over a 14 day treatment period, it will investigate safety, tolerability, pharmacokinetics and serum cortisol levels.

NCT ID: NCT01329939 Completed - Obesity Clinical Trials

The Effect of Montelukast on Asthma Control in Obese Asthmatic Children and Adolescents

Start date: April 2011
Phase: N/A
Study type: Interventional

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.
