Filter by:This study was a 2-treatment period, randomized, multicenter parallel-group study. The overall purpose of this study was to provide long- term safety data for fevipiprant (QAW039) (Dose 1 and Dose 2), compared with placebo, when added to the Global Initiative for Asthma (GINA) steps 3, 4, and 5 standard-of-care (SoC) asthma therapy (GINA 2016), in patients with moderate-to- severe asthma. The purpose of this study was to provide long-term safety data for QAW039 150 mg once daily and 450 mg once daily, compared with placebo, when added to GINA steps 3, 4, and 5 standard-of-care asthma therapy (GINA 2020) in adult and adolescent (≥12 years) patients with moderate-to-severe asthma. The study included 2 cohorts of patients: 1. Rollover patients who had completed any of the four Phase 3 pivotal efficacy studies with QAW039 (QAW039A2307, QAW039A2314, QAW039A2316, or QAW039A2317, hereafter referred to as Studies A2307, A2314, A2316, and A2317), thus providing data for a longer duration of exposure, and 2. New patients who had not previously participated in a study of QAW039, permitting an increase in the number of patients with long-term exposure to QAW039. By including these 2 categories of patients, the total number of patients treated with QAW039 as well as the duration of exposure to QAW039 treatment was substantially increased, supporting evaluation of the safety profile of QAW039.
The purpose of this proof-of-concept study is to determine the effect of Intestinal Microbiota Depletion or Intravenous Administration of C1-inhibitor on Inflammation and Coagulation after Bronchial Instillation of House Dust Mite Allergen and Lipopolysaccharide in Allergic Asthma Patients
This study is designed to identify Dermatophagoides farinae, or Der f, sensitive asthmatics who demonstrate a late phase asthmatic response after Der f inhalation. These subjects may be invited to participate in a planned future study investigating novel asthma treatments.
This is an exploratory randomised matched cohort pilot study. It is hypothesised that adolescents (aged 13-16 years) with asthma attending a secondary care outpatient asthma clinic, will disclose their smoking status to a doctor or nurse, if questioned alone without a parent present and if advised that they will have biological validation of their smoking status using a carbon monoxide monitor. It is a study of 30 subjects, who will be recruited over a period of 6 months.
This study is a multicenter and prospective cohort study of children diagnosed with asthma. Clinical symptoms and signs, quality of life, blood test, and lung function were detected every three months. FeNO detection, chest imaging, and induced sputum smear were detected when necessary. Biological samples will be collected when recruiting and finishing follow-up.
This study is the first administration of GSK2292767 to humans. The study will evaluate the safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of single and repeat inhaled doses of GSK2292767 in healthy smokers. This study is intended to provide sufficient confidence in the safety of the molecule and preliminary information on target engagement to allow progression to further repeat dose and proof of mechanism studies. This is a two part, single site, randomized, double-blind (sponsor open), placebo controlled study. Part A will consist of two 3-period interlocking cohorts to evaluate the safety, tolerability and pharmacokinetics of ascending single doses of GSK2292767 administered as a dry powder inhalation. Part B is planned to follow Part A and progression will be based on an acceptable safety, tolerability and pharmacokinetic profiles. Subjects will receive repeat doses of GSK2292767 once daily for 14 days during Part B.
Contextualization: Exercise is a common triggers of bronchospasm in patients with asthma and healthy subjects. To prevent these symptoms frequently they have to use Short-Acting Beta2-Agonists. However, the cardiovascular effects of salbutamol during and after exercise remain poorly known. Objective: To evaluate the effect of salbutamol on heart rate and blood pressure during exercise in patients with moderate or severe asthma and healthy individuals. Methods: A randomized, double-blind, crossover study will be conducted which 13 individuals with moderate or severe persistent asthma and 13 healthy individuals aged between 20 to 59 years. Patients will perform a maximal effort test on 2 nonconsecutive days, with either 400mcg Salbutamol or 4 placebo puffs. The order of use of placebo or salbutamol will be drawn. During the protocol, heart rate, blood pressure, perception of exertion and peak expiratory flow will be monitored.
This study investigates the propagation of sound from a source in the chest to the chest wall. The methodology of the study will be to place a sound source at a known location in the chest and measure the acoustic response on the posterior chest wall with an acoustic sensor array. The sound source will be created by playing sound down the working channel of a bronchoscope and located anatomically using direct imaging. Subjects will be selected for the study by asking patients undergoing a bronchoscopy procedure whether they would be willing to take part in the experiment in addition to their standard procedure. Procedures will take place in the Bronchoscopy Unit at Addenbrooke's hospital in Cambridge. The Unit runs regional speciality clinics in severe chronic obstructive pulmonary disease, asthma, lung cancer, bronchomalacia and interstitial lung disease and has a nationally significant interventional bronchoscopy service. A subsidiary part of the study (Part A) will collect sound recordings from healthy volunteers and patients with common respiratory diseases using the same acoustic sensor array. This is to create a database of lung sounds and quantify inter-subject variability. The study will last approximately 30 months.
Controlled trial of nebulized salbutamol using jet nebulizer or vibrating mesh technology in children presenting with acute moderate to severe asthma.
This study will assess whether adaption of the Asthma Control Test (ACT) and childhood Asthma Control Test (cACT) for mobile devices improves rate of completion and improves control of asthma in children and adolescents
