Filter by:To follow longitudinally healthy and immune-compromised responses to pneumococcal vaccination, in 60+ individuals towards the development of personalized medicine implementation (minimum enrollments in 2 age categories: young adults[18-25], older adults [55+], within each category: 10+ healthy, 10+ asthma, 10+ immune-compromised [e.g. leukemia or autoimmune disorders]). The approach will profile thousands of molecular components utilizing high-throughput technologies and integrate these data to obtain personalized immune response to vaccination. The study will provide insights into immune response mechanisms specific to asthmatics, immune compromised and healthy individuals, as well as in response to vaccination. Additionally the differences in dynamic response across the two age groups will be investigated.
Mepolizumab is an anti-interleukin-5 ( IL-5) monoclonal antibody that neutralizes IL-5 and reduces eosinophil counts in both sputum and blood. Omalizumab an anti-immunoglobulin E (IgE) monoclonal antibody (mAb) is effective in the treatment of moderate to severe allergic asthma. The aim of this study is to investigate whether subjects not optimally controlled on their current omalizumab treatment, who are eligible for therapy with mepolizumab can be effectively and safely switched to treatment with mepolizumab to improve asthma control. The study will provide data on the efficacy, safety, immunogenicity, and tolerability of mepolizumab when switched directly from omalizumab without any wash-out. The learnings from this study may help guide physicians when substituting one biologic with another for the treatment of patients with severe eosinophilic asthma. The study will be a multi-centre, open-label single arm trial. Patients with severe eosinophilic asthma who are receiving omalizumab, but are not optimally controlled will be eligible to participate. Subjects will remain on their current maintenance therapy including omalizumab throughout the run-in period for a minimum of one week and up to 4 weeks. At Visit 2 (week 0) subjects will discontinue their omalizumab treatment and be switched to mepolizumab 100 mg subcutaneous (SC) every 4 weeks for 28 weeks. The treatment period is 32 weeks, including an Exit Visit/Early Withdrawal Visit, 4 weeks following the subject's last dose of mepolizumab.
The purpose of this research is to study the utility of using the HealtheRx as a tool to recruit eligible patients into the Pulmonary Research Registry (PRR) (IRB 15543B) at the University of Chicago. HealtheRx is an example of a potential recruitment tool that has high reach in populations typically underrepresented in research studies, uses a high tech infrastructure that allows matching of research opportunities to patient characteristics, but that delivers information in a low-tech, patient-centered mode using the printed HealtheRx prescription.
The purpose of this study is to learn the pediatric asthma control status under community management model. To learn the differences of pediatric asthma control status when subjects assigned to community hospitals or Shanghai Childrens Medical Centre. To learn the treatment adherence and the frequency of asthma attack under community management model.
A Randomized, Parallel-Group, Placebo-Controlled, Clinical Endpoint Bioequivalence Study of Generic Fluticasone Propionate 100 µg and Salmeterol Xinafoate 50 µg Inhalation Powder Compared with Advair Diskus® 100/50 in Subjects with Asthma
This is an open-label,partially randomized, four-period study in healthy male subjects to assess the bioavailability and pharmacokinetics of a single dose of AZD7594 when administered intravenously, orally and inhaled via two different dry powder inhalers (DPIs) and a pressurized meter-dose inhaler (pMDI)
Asthma is a chronic, inflammatory disease of the lung characterized by intermittent airway obstruction, airway hyperresponsiveness, presence of activated inflammatory cells, inflammatory mediators, and airway structural changes. Airway smooth muscle (ASM) cells actively participate in the remodelling and inflammatory processes through proliferation, release of proinflammatory cytokines, chemokines, and extracellular matrix (ECM) proteins. Eosinophils as essential inflammatory cells may be of importance in ASM remodelling. It is known that eosinophil induces ASM cells proliferation via the secretion of cysteinyl leukotrienes in asthmatics. However there is a possible direct eosinophil-ASM cells functional interaction by adhesion processes. It has been shown that integrins modulate ASM proliferation and contractile protein expression demonstrating allergen-induced ASM remodelling in an animal model of allergic asthma. Wingless/integrase-1 (WNT) signaling regulates not only a wide range of developmental processes, but its aberrant activation can lead to disease. Recently, it was confirmed that genes polymorphisms in the WNT signaling pathway are associated with impaired lung function in childhood asthma. It was also found for the first time a relevant role of noncanonical WNT signaling in TGFβ-induced ECM expression by ASM cells and identified WNT-5A is the most abundant WNT ligand with increased expression in asthmatics. It demonstrates that WNT-5A could contribute to remodelling of the airways. Unfortunately, the effect of eosinophil on WNT secretion by ASM cells at present is unknown. Despite the widely acknowledged significance of eosinophils in asthma pathogenesis, the mechanism of eosinophil induced ASM remodelling is unsolved.
This is a randomized, single-blind, placebo-controlled, sequential-group study to assess the safety and tolerability as well as how the drug (AZD7594) affects the body (pharmacodynamics [PD]) and how the body affects the drug (pharmacokinetics [PK]) when AZD7594 is given as single and multiple ascending doses once daily by inhalation to healthy male Japanese subjects, compared with placebo (non-active drug)
This study aims to evaluate the asthma control status, asthma symptoms (severity, frequency, and limitations on activities, etc.), QOL, and use of drugs for asthma attack in adult asthma patients.
The overall goal of this study is to adapt and preliminarily validate an intervention based on evidence based approaches to assist smoking parents and other family members of inner-city children ages 4 to 12 with asthma to stop smoking.This study aims (1) to adapt existing guideline-based materials used in adult medicine to create a system- and provider-level intervention for pediatrics and (2) to evaluate feasibility and acceptability of (a) procedures to recruit inner-city, ethnic minority parents and (b) intervention procedures, and to estimate intervention effects.
