Filter by:The Sponsor is developing the test medicine, AZD4604, as a potential treatment for asthma. Asthma is a common lung condition caused by inflammation (swelling) of the breathing tubes that carry air in and out of the lungs, causing occasional breathing difficulties such as wheezing, shortness of breath, chest tightness and cough. This study in healthy volunteers will explore the following questions. - Does the test medicine cause any important side effects? - What are the blood levels of the test medicine and how quickly does the body get rid of it? - How much of the test medicine gets into the bloodstream? - How does the body break down and get rid of the test medicine? This study will take place at one non-NHS site in Nottingham, and plans to enrol 8 healthy men and women aged 18-65 years who will be involved in both parts of the study.
The purpose of this retrospective medical record review is to describe the real-world clinical effectiveness of dupilumab with patients in the United Kingdom with severe asthma.
This study examines the impact of home-based monitoring of respiratory function in asthma patients via a smartphone-based vocal biomarker platform. Previous work from cross-sectional studies has indicated that brief voice samples, analyzed by machine learning models, can predict the presence of respiratory conditions (asthma, COPD, ILD, COVID-19 and persistent cough) with an accuracy of approximately 70%. The present study seeks to extend these findings to establish whether the same vocal biomarker models can accurately track changes in respiratory function in asthma patients, and whether this capability, when incorporated into a smartphone app similar to those used for home-based asthma management, can improve relative level of asthma control.
The goal of this observational study is to explore the health impacts of exposure to nontailpipe vehicle air pollution. The main question it aims to answer is: Does short term exposure to increased non-tailpipe course mode PM induce negative respiratory responses in adults living with asthma? We will recruit 48 non-smoking adults with mild-moderate asthma. Participants will be recruited from central and east London Participants will be exposed to three contrasting air quality environments, in field laboratories at the following locations: 1. High-speed continuous traffic location, to enhance tire wear emissions 2. An urban background location away from nearby traffic sources 3. A busy road junction characterized by stop-go traffic to enhance emissions from brake wear Sites 1 and 2 are permanent air quality measurement supersites. Site 1 is located close to a major trunk road in Central London (Marylebone Road). Site 2 is a suburban park in South London (Honor Oak Park). An additional measurement location will be established at Imperial College London's (ICL) White City campus (Site 3) for the duration of the study using ICL's mobile measurement facility, equipped with the same highly time-resolved chemical composition measurement capability as the supersites. To maximise exposure to different air quality environments participants will intermittently cycle on static exercise bikes at a standardised intensity of 60% estimated VO2max for a duration for 2.5 hours at the field laboratories. Comparators variables: Air quality will be monitored at all three sites for the duration of the testing visits (approximately 5 hours). Air quality parameters that will be recorded are PM2.5, PM10, NO2, NO, NOX, O3, Organic Mass, NO3, SO4, NH4, elements and black carbon. Outcome variables: The primary outcome of the study is lung function as measured by Forced Expiratory Volume in one second (FEV1). With secondary health endpoints including: Spirometry (FVC, FVC/FEV1 ratio, z Scores), fractional expired nitric oxide (FeNO), oscillometry, asthma symptoms, MRC breathlessness score, asthma control test and Asthma Quality of Life Questionnaire (AQLQ). Blood, nasal mucus and urine samples will be collected. Measure will be collected before after and 24 hours after exposure.
The primary objective is to determine whether continuous sensing, control and mitigation of home indoor air quality influences the frequency of asthma related symptoms, as measured by Serum IgE, Spirometry with exhaled Nitric Oxide, missed school and workdays, need for pharmacologic intervention (albuterol, oral steroids), frequency of sick visits to pulmonologist or primary care provider (PCP), urgent care / emergency department visits, and hospitalizations
This study is a randomized, double-blind, dose-escalating phase I clinical study to evaluate the safety, tolerability and pharmacokinetics of 9MW1911 injection in healthy subjects.
Public Health England have estimated that 36,000 excess deaths occur each year due to UK air pollution. Respiratory inhalers produce 3% of NHS greenhouse gas production. The two main inhaler device categories are pressurised Metered Dose Inhalers (pMDIs) and Dry Powder Inhalers (DPIs). The chemical propellant in pMDIs is the majority cause of inhaler carbon footprint, with pMDIs having an 18 times higher carbon footprint than DPIs. The rates of asthma in the UK population are amongst the highest worldwide and its mortality rate remains amongst the worst in Europe. A pre-existing Audit and Feedback (A&F) quality improvement project (QIP) is being undertaken by NHS West Yorkshire Integrated Care Board (ICB) with the aim of improving asthma outcomes and reducing the environmental impact of inhalers in primary care. The A&F being utilised here has been validated locally in two peer reviewed studies and is now standard practice in the region. There is convincing evidence that A&F has a positive effect on enacting behaviour change, especially where behaviour change is related to prescribing with low baseline compliance with guidelines. However, the evidence base is poor on which design features of A&F produce enhanced results. There is supporting evidence from local studies suggesting that posted paper A&F may be more effective at producing behaviour change than emailed copies of A&F alone. This study seeks to randomise the primary care practices within the pre-arranged QIP, to receive either a paper and emailed A&F report bimonthly for the duration of the study period, or to receive an emailed A&F report alone. The primary outcome of the study would be a comparison of the number of 'low-global warming potential' inhalers prescribed as a percentage of the total prescribed inhalers from each intervention group.
An open-label, single-arm, non-interventional, prospective, multicenter study involving primary data collection within real-world settings for patients who receive benralizumab for treatment of severe uncontrolled eosinophilic asthma
This research is studying whether changing an individual's behaviors may have an impact as a treatment or outcome for asthma. The purpose of this study is to implement and evaluate an asthma self-management intervention through multiple locations in the United States that is tailored to the challenges older adults face and is based on an individual behavioral theory of change. Eligible participants will be enrolled and participate for six weeks in the SOAR intervention.
The goal of this multi-centre, prospective, open-label, single-arm, post-market clinical follow-up study is to further strengthen the already existing clinical evidence for supportive treatment and symptoms alleviation in asthma by evaluating the clinical efficacy of Ectoin® Inhalation Solution in paediatric and adults patients with mild to moderate asthma.
