Filter by:Most asthma is allergic in origin. The purpose of this study is to better understand the airway immune response to inhaled allergens in order to identify factors that promote asthma.
Interleukin (IL)-5 is the main cytokine responsible for the activation of eosinophils, hence therapeutic strategies have been investigated and developed for clinical use. Biologics targeting IL-5 and its receptor (first mepolizumab and subsequently, reslizumab and benralizumab), have been recently approved and used as add-on therapy for severe eosinophilic asthma resulting in a reduction in the circulating eosinophil count, improvement in lung function and exacerbation reduction in patients with severe asthma. Response to biologic therapies in severe asthma is variable, with patients being either non-responders, responders or super-responders. There is currently no explanation for this broad variation in response. It is important to examine whether these patients have distinct characteristics that could help the treating physician in making the correct diagnosis in clinical practice. Aim of this clinical study is to evaluate the efficacy of mepolizumab, a humanized IL-5 antagonist monoclonal antibody in patients with late-onset severe eosinophilic asthma with fixed obstruction and to identify the characteristics of non-responders and super-responders under mepolizumab treatment. This study is considered as non-interventional and every procedure included is happening in a clinical routine for the diagnosis and phenotyping of the asthmatic patients. Hypothesis includes the efficacy of mepolizumab treatment in late-onset severe eosinophilic asthmatic patients with fixed obstruction and relation to clinical and inflammatory biomarkers. Patients will be collected from the outpatient clinics of bronchial asthma from each site included (8 in number) which cover the whole population of Greece. Overall, this is a prospective multicenter study including eight Pulmonary Clinics. Five Pulmonary University Clinics, two of National Health System and one Army General Hospital in Thessaloniki. The study will include a screening period of up to 2 weeks to assess eligibility and obtain written informed consent, a mepolizumab treatment period of 52 weeks, once every 4 weeks, including follow up visits every 3 months during treatment. The study population will consist of 45 patients with late-onset severe eosinophilic asthma and fixed obstruction receiving mepolizumab, aged 20 and above.
The first part will be a comparative cross-sectional study to identify the frequency of ILO and other comorbidites among participants with asthma compared to a group of reference subjects without asthma, matched for age- and gender and race. The second part will be a longitudinally observational study study following participants for one year after the cross-sectional study. The Maat-scores ILO-symptoms and asthma-outcomes longitudinally will be evaluated, .
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.
The purpose of this study is to assess the evolution of disease control, health-related quality of life, and the risk of severe asthma exacerbations in children and adolescents with persistent asthma in Spain at short, mid and long-term follow-up. Patient-reported information in this project is collected by computer assisted telephone interviews (CATI) and a mobile application (ARCA App).
Asthma, which are one of the most important causes of morbidity and mortality both in the world and in our country, constitute a very serious social and economic burden. An estimated 300 million people suffer from asthma worldwide, which is a major public health problem. Asthma is complex and heterogeneous chronic airway diseases that require a multifaceted approach. In asthma, small airways represent key regions of airflow obstruction. Although small airway dysfunction is known in chronic airway diseases, the importance of small airway dysfunction on disease control, exacerbations and quality of life, and the importance of taking place among treatable targets is not clear. Thus, there is an unmet need to assess its role in the control of the disease. Therefore, our primary aim in the study is to determine the frequency of small airway dysfunction measured by impulse oscillometry in Asthma patients. Our secondary aim is to evaluate the role of small airway dysfunction in disease severity, disease phenotypes, disease control, quality of life and its effect on predicting the risk of exacerbation and its role among treatable targets in Asthma.
The primary objective of the study is to characterize the patients who initiate treatment for asthma with DUPIXENT® in a real-world setting to understand the attributes of treated patients in real life. This includes characterization of: - Patient demographics (eg, gender, age, and race) - Patient baseline characteristics (eg, prior medications and procedures, medical history, asthma history, weight, height) The secondary objectives of the study are: - To characterize real-world use patterns of DUPIXENT® for asthma - To assess the long-term effectiveness of DUPIXENT® in asthma patients in a real-world setting - To assess effectiveness on comorbid type 2 inflammatory conditions in asthma patients treated with DUPIXENT® - To collect long-term safety data on study participants in the real-world setting
This is a randomized controlled trial to investigate efficacy of a internet-delivered CBT for anxiety related to asthma.
This study will evaluate how adolescents take their asthma medications using an electronic medication monitor.
This study aims to answer the question whether daily oral vitamin D supplementation can reduce the risk of respiratory or lung complications in children and adolescents with sickle cell disease. Respiratory problems are the leading causes of sickness and of death in sickle cell disease. The investigators hypothesize that daily oral vitamin D3, compared to monthly oral vitamin D, will rapidly increase circulating vitamin D3, and reduce the rate of respiratory complications by 50% or more within the first year of supplementation in children and adolescents with sickle cell disease. This study is funded by the FDA Office of Orphan Products Development (OOPD).
