Filter by:Rationale for the current trial is to demonstrate 24 hour bronchodilator efficacy and safety of tiotropium 5 µg administered once daily (in the evening) which is regarded beneficial for the compliance and convenience of the patient in comparison to placebo. Further the rationale is to evaluate efficacy and safety of tiotropium 2.5 µg administered twice daily delivered by the Respimat® inhaler in comparison to placebo and tiotropium 5 µg administered once daily (in the evening) delivered by the Respimat® inhaler in patients with moderate persistent asthma. Rationale for the pharmacokinetic subinvestigation is to evaluate the 24 hours exposure to tiotropium in patients with moderate persistent asthma when administered 5 µg tiotropium once daily (in the evening) or 2.5 µg tiotropium twice daily.
Spirometry is a recommended component of asthma diagnosis and treatment in the primary care setting, yet few primary care providers report routine use of spirometry in the provision of care for their asthma patients. Misclassification of asthma severity has been reported when assessment is based on symptoms alone. This misclassification can lead to inadequate treatment that may result in increased morbidity and increased healthcare utilization/cost. However, even when spirometry is utilized to aid in asthma severity classification, primary care providers have a high rate of failing to meet the quality goals for testing established by the American Thoracic Society. The goal of this study is to evaluate the effectiveness of the Spirometry Fundamentals™ tool in training primary care providers and their staff in producing high-quality flow-volume curves as compared to existing training modalities and to gather information in a 'real-world' setting that can be used to improve Spirometry Fundamentals™.
The purpose of the study is to compare the efficacy and safety of fluticasone furoate/vilanterol (GW642444) inhalation powder administered once daily with fluticasone propionate/salmeterol administered twice daily in adolescent and adult subjects 12 years of age and older with persistent bronchial asthma over a 24-week period.
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.
To compare the efficacy of combination therapy of montelukast plus low dose inhaled budesonide and single therapy of medium dose inhaled budesonide on asthma control such as inflammatory markers and clinical indicators and to compare treatment response according to leukotriene related genotypes in elderly patients with asthma
The aim of the study is to evaluate the efficacy of Alvesco in patients with persistent asthma including or excluding allergic components over 3 months, especially in the spring season. Alvesco will be inhaled by a metered-dose inhaler. The study will provide further data on safety and tolerability of Alvesco .
Specific immunotherapy for subcutaneous application: Dose finding study to evaluate the correct dose. 4 concentrations of a birch pollen allergen extract are applied in this study. Duration of therapy 20 weeks. Primary criterion is the Conjunctival Provocation Test (CPT), i.e. comparison between treatment arms of increased amount of quantities of allergen to provoke a positive CPT at the end of treatment.
The investigators hypothesize that different placebos will have different effects on subjective and objective asthma outcomes compared with actual therapy and natural history. . Subjects with asthma are randomly treated with placebo inhaler, placebo acupuncture, albuterol inhaler, or "no treatment" in random order, on three different occasions each. At each of the 12 visits, spirometry is performed repeatedly over 2 hours. Maximum FEV1 achieved and an 11-point, self-reported scale of improvement are examined.
This study examines the pharmacokinetic profile of Armstrong's proposed Epinephrine Inhalation Aerosol USP, an HFA-MDI (E004), in healthy male and female adult volunteers. Safety of E004 will also be evaluated, under augmented dose conditions.
Inhaled corticosteroids (ICS) are considered first-line treatment for persistent asthma, yet little is known about the genetic factors that influence response to this therapy. This study seeks to quantify response to ICS therapy in African American and white patients, as well as look for genetic markers that predict treatment response.
