Active clinical trials for "Asthma"

Primary Objective: The primary objective of the study is to characterize patients initiating DUPIXENT for asthma in a real-world setting, with respect to their medical history, including asthma history and asthma treatment history, socio-demographic, biomarkers (including Fractional exhaled nitric oxide [FeNO]), and concomitant treatments for asthma. Secondary Objectives: The secondary objectives of the study are: To characterize real-world use patterns of DUPIXENT for asthma (eg, most commonly used regimens, reason for initiation of new asthma treatments, concomitant therapies, treatment durations, and reasons for discontinuation and/or switching) To assess the effectiveness of DUPIXENT in asthma patients in a real world setting (lung function improvement, exacerbation rate, asthma control) To assess comorbid type 2 conditions (atopic/allergic) and patterns of use and effects of treatment in comorbid conditions in asthma patients treated with Dupixent To collect data on HealthCare Resource Utilization (HCRU) To collect safety data on study participants in the real-world setting.

To identify asthma-related physiological changes observed by wearable devices in real-world conditions by monitor multiple sensing modalities (e.g., heart rate (HR), heart rate variability (HRV), activity level, spirometry, coughing sounds) in order to find reliable signatures of impending asthma exacerbation and systematically explore any challenges on the use of wearable technologies.

This is a prospective, observational study to investigate the agreement of the Leo device signal derivation with gold standard asthmatic testing in recently exacerbated asthmatic children. This study is designed for engineering validation of a wireless, wearable device (Leo) for assessing clinical control of children recovering from acute respiratory event such as asthma attack. The Leo device will monitor chest impedance, ECG and body position to calculate parameters such as respiration rate, heart rate, lung volume, tidal breathing flow and volume curves, and body position. These parameters will then be used to train and algorithm to assess clinical control of asthma.

Researchers found that impairments in the cardiopulmonary system caused by acute exposure to ozone were outweighed by repeated exposures to ozone. The goal of this study is to confirm there will be an adaptation similar to what was previously proved but in individuals with asthma and exercise-induced bronchoconstriction (EIB). The purpose is to examine adaptive responses in a randomized cross-over trial in which physically active individuals will perform submaximal exercise on five days in ozone and filtered air exposures separated by a washout period.

The primary objective of this project is to extensively characterize the endotypes of pre-schoolers (0 to 6 years) and school-age children (6 to 12 years) with SA using an integrated approach, combining a description of their phenotype (asthma symptoms, atopy, and lung function) associated with histological (airway inflammation and remodelling), immune (innate and adaptive immunity), metabolomics, and microbiota analyses. This goal shall be achieved by an unsupervised in-depth analysis of patients requiring bronchial endoscopy, with bronchial alveolar lavage (BAL) and bronchial biopsy, as part of their clinical assessment.

This study aims to iteratively develop, refine and test the Improving Asthma Care Together (IMPACT) Intervention for school-age children (7-11 years) with persistent asthma and their parents.

The overall aim in Part 1 is to compare the pharmacokinetic (PK)/pharmacodynamics (PD) relationship in intravenous (IV) versus subcutaneous (SQ) terbutaline sulfate to identify the optimal IV dosing range for use in Part 2. The overall aim in Part 2 is to evaluate the optimal IV dosing of terbutaline sulfate based on PD response and safety data.

It is planned to conduct a study of nitric oxide metabolites (nitrates and nitrites), L-arginine, arginase-1, and asymmetric dimethylarginine in patients with bronchial asthma and chronic obstructive pulmonary disease, followed by observation to assess the prognosis of the disease.

The aims of this project are twofold: to characterize indoor air quality components obtained from apartments with gas stoves and open kitchens in a cohort of Black adults with uncontrolled asthma recruited from federally qualified health centers and enrolled in the parent study. to conduct a comprehensive assessment of feasibility, implementation, and acceptability of the study.

This randomised, prospective, controlled parallel study aims to evaluate the role and potential of the aflo™ digital platform for improving asthma control, inhalation technique and adherence in patients who use metred dose inhalers (MDI). The study will recruit 104 patients with uncontrolled asthma in the North-West of Northern Ireland. Fifty two patients will remain on standard care over 24-weeks and 52 will combine standard care with the aflo™ platform. The data collected over a 24-week period will be used to determine 1. whether the aflo™platform improves inhalation technique and user adherence to prescribed medication and 2. Lead to better asthma control and reduced symptoms as measured by the Asthma Control Test (ACT). During the study clinicians will be able to remotely monitor and review user analytics via a clinical dashboard. ACT measurements will be recorded at start and end of study. The study aims to test the functionality and impact of automated inhaler technique with real-time feedback, adherence prompts and air quality data sharing for patients who use metered dose inhalers (MDI) using the newly developed aflo™ digital respiratory management platform.
