Filter by:This study is designed to determine whether TC-6987 improves respiratory function in subjects with asthma by reducing airway hyper-responsiveness and inflammation.
Bronchial asthma is a common disease and frequently encountered disease of respiratory apparatus. It has very complex mechanism and multiple inducing factors. This study will focus on a new Chinese therapy on Bronchial asthma, analyzing the treatment mechanism of internal and external use, based on Traditional Chinese Medicine (TCM) theory and clinical practice. The study will also investigate the efficacy of the Chinese drugs and treatments on Bronchial asthma, and provide an effective therapy for this disease.
The primary objective of the study is to evaluate the long-term safety of reslizumab at a dosage of 3.0 mg/kg every 4 weeks for approximately 24 months in pediatric and adult patients with eosinophilic asthma as assessed by adverse events, physical examination findings, vital sign measurements, and concomitant medication usage throughout the study (every 4 weeks), clinical laboratory test results, and measurement of antidrug antibodies.
We are doing this study to learn how genes affect the way that people, specifically Black people, respond to treatment for asthma. Recent studies suggest that people respond differently to some asthma medications (eg Serevent, Foradil). Some people feel better when they use these inhalers, but others may not, and some people get worse. It seems that this difference shows up more often in Blacks than in Whites, which is why we are looking for Black subjects for this study. In all people, this difference seems to depend on their genes or DNA. This study is comparing the use of long acting asthma medications (Serevent, Foradil) to Tiotropium (Spiriva) for the treatment of asthma. Spiriva is used to treat chronic obstructive pulmonary disease (COPD). This study will help to see if this medication is also useful for treating asthma and whether it works better for some people than the current asthma medications.
Traditional, continuous-mode nebulizers such as the English-Wright nebulizer are designed to operate continuously with tidal breathing. As inhalation accounts for only about one-third of the respiratory cycle, two-thirds of the continuously produced aerosol is lost to the environment possibly posing a hazard any fellow-patients, family members, or health-care workers in the vicinity. The English-Wright has been the only American Thoracic Society (ATS)recommended device available on the market. Recently Roxon Medi-Tech has announced the discontinuation of the English-Wright nebulizer. For these reasons it is necessary to review the use of other nebulizers such as the AeroEclipse II breath-actuated nebulizer and further validate their performance. The investigators expect to show equivalence between the AeroEclipse II and the English-Wright nebulizers.
Research Title: The effect of vitamin D replacement on airway reactivity, allergy and inflammatory mediators in exhaled breath condensate in vitamin D deficient asthmatic children. Introduction: Vitamin D seems to play a role in allergic and asthmatic reactions as an immunomodulator. Asthma disease involves inflammatory process in the lower respiratory tract and airway hyperreactivity. Aim: To assess the effect of Vitamin D replacement on airway reactivity, and allergy and inflammatory mediators in exhaled breath condensate in vitamin D deficient asthmatic children. Design: Double blind placebo control prospective study comparing the effect of Vitamin D replacement and placebo on airway reactivity, allergy and inflammatory mediators in exhaled breath condensate in asthmatic pediatric population with vitamin D deficiency. Participant selection: The study group will consist of pediatric patients (age 6-18 years) followed and treated at the Pediatric Pulmonary Unit at the investigators hospital. Patients with mild-moderate asthma with low or insufficient vitamin D levels that are currently not receiving anti-inflammatory treatment will be recruited. Sample size: 60 participants in the two groups (30 receiving Vitamin D and 30 receiving placebo). Intervention: Vitamin D (14000 units) or placebo will be provided in a similar appearance preparation once weekly for 6 weeks between visit two and three. Three visits will be conducted. Each subject will undergo evaluation including a respiratory questionnaire (visit 1), methacholine challenge test with determination of PC20 (visit 1 or 2 and visit 3), exhaled nitric oxide (eNO) (visit 2, 3), and exhaled breath condensate (EBC) (visit 2,3). Venous blood will be analyzed for complete blood count + eosinophils (visit 1, 3), IGE levels (visit 1, 3), and Vitamin D levels (visit 1, 3). Prick skin test for inhaled allergens will be performed (visit 2, 3). Primary end point: Airway reactivity as assessed by methacholine challenge test. Secondary outcome parameters: All other parameters are the secondary end points.
This study will compare the absolute and relative effectiveness and cost-effectiveness of asthma management in patients in the USA on inhaled corticosteroid (ICS) maintenance therapy as HFA-BDP (Qvar®) pressurised metered dose inhaler (pMDI) compared with fluticasone propionate (FP) pMDI. .
This study will be a repeat-dose, double-blind, randomized, placebo controlled, three-way crossover study in patients with persistent bronchial asthma to compare the effect of morning (AM) and evening (PM) dosing with fluticasone furoate (FF)/Vilanterol (VI) inhalation powder on lung function. Following screening there will be a run-in period of 14 days. There will be 3 treatment periods; drug at AM, drug at PM and placebo, which will last for 14 days each with a 14-21 day washout period between starting the next. Key assessments include; forced expiratory volume in one second (FEV1), peak expiratory flow (PEF), vital signs, electrocardiograms (ECGs), adverse event (AE) monitoring and laboratory safety tests.
This is a Phase 3, multicenter, randomized, double-blind, placebo-controlled, parallel-group study to evaluate the efficacy, safety, and immunogenicity of treatment with reslizumab in patients with eosinophilic asthma.
GSK2190915 is under development as an oral controller for the treatment of adult and pediatric asthma. This study is an open label, single and repeat dose escalation study, in children with asthma. It will investigate the pharmacokinetics of GSK2190915 in children, aged from 1 to 12 years old inclusive, to determine how the dosage regimen for GSK2190915 in a pediatric population should be adjusted to achieve approximately the same level of systemic exposure that is safe and effective in adults.
