NCT01147744
To evaluate the efficacy, dose response and safety of four doses of GSK2190915 in tablet form (10mg, 30mg, 100mg and 300mg) administered once daily, over 8 weeks compared with placebo in adolescent and adult subjects (12 years of age and older) with persistent asthma. These data will form the basis for the selection of the optimal daily dose of GSK2190915 to be carried forward in Phase III asthma studies. The study also includes Fluticasone Propionate Inhalation Powder (100 mcg, twice daily) and Montelukast (10mg, once daily) to allow for an exploratory analysis of the efficacy of GSK2190915 versus a low dose inhaled corticosteroid and a leukotriene receptor antagonist.
NCT01699204
This experiment is designed to test the hypothesis that oxidative stress is responsible for changes in airway responsiveness in humans exposed to diesel exhaust.
NCT01196377
Our overall objective is to model a pediatric Acute Asthma Clinical Decision Rule (ADR) for personalized medicine by identification of treatment-response phenotypes that are important determinants of outcome. The Specific Aim of this study is to determine the feasibility of this approach by enrolling a pilot cohort of 16 participants in this DBRCT of 4 different albuterol treatment regimens, 2 of which will use 10mg/hr and 2 of which will use 25mg/hr. Within these dosages there will be a pulsed-treatment regimen and a continuous regimen.
NCT01901354
This study will compare two ventilator modes in mechanically ventilated patients with acute lung injury. Acute lung injury (ALI) is a condition in which the lungs are badly injured and are not able to absorb oxygen the way healthy lungs do. About 25% of patients who are ventilated get ALI. ALI causes 75,000 deaths in the US each year. Ventilators can be set to work in different ways, called modes. One mode, called ARDSNet, pumps a small amount of air into the patient's lungs and then most of the air is released prior to the next breath. Another mode, called Airway pressure release ventilation (APRV), keeps air in the lungs longer between breaths. Both of these modes are currently used at this hospital. The investigators think APRV may help patients with ALI, but we do not know for sure.
NCT03294772
It is well known that attending Day Care Centres (DCCs) can lead to an increase in the frequency of infections, due to the high incidence at this age and also the ease of transmission among children. This high incidence respiratory tract infections (RTIs) and acute gastroenteritis can also have a significant impact on the cost of health care systems, increasing the number of medical visits, hospitalizations and prescribing medications as symptomatic drugs or unnecessary antibiotics in some cases.The aim of the study was to determine whether a multifactorial hand-hygiene program (handwashing with soap and water vs hand sanitizer vs control group) reduce episodes due to RTIs and gastroenteritis in children attending DCCs. In addition, analyze the cost-effectiveness of these interventions.
NCT00016523
This multicenter trial tested whether inhaled nitric oxide would reduce death or the need for oxygen in preterm infants (less than 34 weeks gestational age) with severe lung disease.
NCT00005776
Respiratory failure in term newborns is associated with increased rates of death and long-term neurodevelopmental problems. This large international multicenter trial randomized newborns who had failed to respond to intensive care, including high levels of ventilator support, to receive either inhaled nitric oxide (iNO) or 100 percent oxygen to test whether iNO would decrease their risk of dying or requiring temporary lung bypass. Infants were followed during their initial hospitalization; their outcome was assessed at 18 to 24 mos of age.
NCT02433535
This purpose of this clinical trial is to determine if a statin drug, Simvastatin, added to inhaled corticosteroids and bronchodilators can reduce systemic and airway inflammation, improve lung function and symptoms, and reduce acute exacerbations in patients with severe asthma who are already on controller inhaler therapy. This proposed investigator-initiated, single-center, early Phase II, cross-over, randomized clinical trial, titled "Randomized Trial of Simvastatin for the Treatment of Severe Asthma", will be conducted at the University of California, Davis Medical Center (UCDMC) in Sacramento, CA. This trial will evaluate Simvastatin for treatment of asthma in subjects with severe asthma (as defined by the American Thoracic Society (ATS)), who are already taking inhaler controller therapy. The investigators plan to enroll 24 patients with severe allergic asthma. The investigators hypothesize that treatment with Simvastatin 40 mg (administered once daily) will not only improve indicators of airway and systemic allergic/Th2 inflammation, but will also reduce acute exacerbations and improve lung function. All patients will be on standard controller therapy including appropriate doses of inhaled corticosteroids and long-acting bronchodilators.
NCT01276652
This study examines the feasibility of assessing sleep and circadian rhythmicity in critically ill patients undergoing mechanical ventilation. Secondarily, it will examine the feasibility of reducing subject exposure to environmental light and noise and of delivering routine care according to classical day/night routines.
NCT03225534
This proposal relates to the testing of several specific hypotheses in a subset of 500 participants in the Canadian Healthy Infant Longitudinal Development (CHILD) Study. These 500 now have complete data from the time of recruitment (in pregnancy) to age 1 year. The primary purpose of this proposal is to identify risk factors for early allergic outcomes and biomarkers that may predict future disease. These 500 infants will provide critical preliminary data, not only related to early outcomes, but also to inform analytical plans for the full CHILD cohort.
NCT03029299
BioFire Diagnostics, LLC (BioFire; a bioMerieux company), has developed a multiplexed molecular-based in vitro diagnostic platform for infectious disease testing known as the FilmArray. The FilmArray Respiratory Panel (RP) EZ is a test designed for use with the FilmArray 2.0 EZ Configuration instrument that identifies common bacterial and viral microorganisms associated with respiratory tract infections from a nasopharyngeal swab (NPS) specimen collected in viral transport media (VTM). The RP EZ was granted CLIA-waived classification by the FDA in October 2016 and is the first highly-multiplexed molecular test to receive this designation. The purpose of this study is to measure patient outcomes following implementation of the RP EZ test and to also gather data about physician office workflow and user interactions with the device. These data will be used to understand how the adoption of such tests may influence patient care in the CLIA-waived setting.
NCT00318630
This study is to investigate the effects of AVANDIA on the asthmatic response.
NCT00461812
The research hypothesis for the proposed study asks the question, can Asmanex® demonstrate comparable anti-inflammatory therapeutic efficacy to the combination product, Advair® in control of mild persistent asthma? The purpose is to demonstrate that the anti-inflammatory protection afforded by monotherapy with an inhaled steroid (Asmanex®) is comparable to combination therapy with Advair® 100/50, when measured by this standard methodology (methacholine bronchoprovocation) in subjects with mild persistent asthma.
NCT01612936
The specific hypothesis for this study is that there are fundamental differences in T effector and T regulatory cell responses in the lung to allergens in allergic asthma (AA) when compared to allergic nonasthmatics (ANA) that account for the difference in clinical responses. We will address this by comparing T cell responses in AA versus ANA subjects. These experiments will correlate T cell responses with measures of airway physiology using state-of-the art lung imaging and examine mechanisms controlling T cell activation in the airways of AA and the function of airway T regulatory cells during AA.
NCT02915068
The investigators propose to modify and expand the internationally-recognized evidence-based Physician Asthma Care Education (PACE) program to make it a suitable tool for training primary care clinicians on the effective use of EHRs at the point of care. The investigators will first develop the EHR edition of PACE (EHR-PACE) through literature and expert review of best practices for clinicians interacting with patients in the presence of computer systems in the exam room. They will then establish the feasibility and potential impact of EHR-PACE via a randomized design on 125 patients of 20 physicians who receive the intervention on the following outcomes via survey 3 and 6 months post-intervention: patient satisfaction with the physician's performance, asthma control, and asthma-related quality of life. Outcomes will be assessed on patients, but physicians will receive the intervention. Patients will not know which arm their doctor was randomized to. The pilot trial will compare two groups of primary care physicians who see patients with asthma in clinics equipped with certified EHRs. It is hypothesized that patients of physicians who receive EHR-PACE training will achieve better outcomes compared to physicians who do not receive EHR-PACE.
NCT03281941
ToAST study is a pilot study aiming to establish the safety profile of using inhaled capsaicin challenge in patients with severe asthma. The investigators will also explore the differences in cough symptoms and threshold in patients with and without bronchial thermoplasty.
NCT03273764
To develop a comprehensive 'Clinical RD score' for decision making for administration of Surfactant in respiratory distress syndrome in preterm infants with gestation of 26 0/7 - 34 6/7 weeks and to assess the validity of this 'clinical RD score' on a different subgroup of patients with similar gestational age.
NCT03055793
The greater efficacy of combination therapy led to the development of fixed combination devices which simultaneously carry both glucocorticosteroid and a LABA (eg stable combinations of fluticasone-salmeterol, budesonide-formoterol). Fixed combinations are easier to use for patients, potentially increasing compliance, and ensure that the LABA always accompanied by glycocorticosteroeides1. From the available combinations of the combination of budesonide-formoterol can be used both in maintenance therapy and for the relief of symptoms due to the rapid onset of action of formoterol compared with salmeterol. Both components of budesonide-formoterol combination when administered on demand contribute to strengthening protection from severe exacerbations in patients receiving combination therapy for maintenance, and enable improvement of asthma control at relatively low doses of ICS.
NCT00994175
Background: \- Individuals who have severe asthma that is not easily controlled by current treatments are in need of new treatments to prevent potentially life-threatening asthma attacks. Experiments in mice have found that a medication called pioglitazone hydrochloride (Actos ), which is used to treat patients with diabetes, may be effective for treating severe asthma. Researchers are interested in determining whether Actos is effective in improving the quality of life in subjects with severe asthma who continue to have symptoms despite maximum standard medical therapy. Objectives: \- To assess the effectiveness of pioglitazone hydrochloride as a treatment for patients with severe asthma that is not controlled by standard treatments. Eligibility: \- Individuals between 18 and 75 years of age who have been diagnosed with and treated for severe asthma for at least 1 year. Design: * Potential participants will have a screening visit to determine eligibility for the study. The visit will involve breathing tests, chest x rays, heart and lung monitoring, and blood tests. * Eligible participants will have a full medical history and will answer a series of questionnaires about their quality of life with asthma. * Phase 1: Patients will record lung function and asthma symptoms morning and evening for 4 weeks. At the end of this period, patients will be evaluated with breathing, allergy, and blood tests, as well as questionnaires. Patients will also provide a sputum sample. * Phase 2: Patients will receive regular doses of either pioglitazone hydrochloride or a placebo for 16 weeks. Patients will return to the National Institutes of Health every 4 weeks for tests. * Phase 3: Wash-out period without study drugs for 4 weeks, similar to Phase 1. * Phase 4: Patients will receive regular doses of either pioglitazone hydrochloride or a placebo for 16 weeks. Patients who received placebo will be given the study drug, and vice versa. Patients will return to the National Institutes of Health every 4 weeks for tests. * Phase 5: Medications will be stopped, and patients will return to the National Institutes of Health 4 weeks later for final tests.
NCT01255826
The purpose of this study is to evaluate sustained lung inflation followed by early nCPAP as delivery room ventilatory management for preterm neonates at risk of respiratory distress syndrome in reducing their need for mechanical ventilation and ameliorating lung injury without inducing adverse effects compared with intermittent bag and mask ventilation.
