Filter by:The purpose of the study is to Evaluate the safety, tolerability, pharmacodynamics and pharmacokinetics of single inhaled doses of VR942 in healthy subjects (part 1) and repeated doses in mild asthmatics (part 2).
Background: Research shows that restricting calories has a positive effect on immune cell health in healthy people. Researchers want to learn if it will help people with asthma. They want to better understand how the body s immune response and lung function responds to short-term calorie restriction. For this, they want people to fast (no food or drink except water) for 24 hours. Objective: To explore the benefits of calorie restriction in people with asthma. Eligibility: Healthy people ages 18 to 60 who have a history consistent with asthma and prior documentation of airflow obstruction or wheezing. Design: - Participants who have taken part in asthma research at NIH will be screened with a telephone interview. All other participants will have a medical history, blood tests, and physical exam. - Eligible participants will return to the NIH Clinical Center one morning for 2 hours. They will be fed breakfast. They may have blood and urine tests. - Participants will then fast for 24 hours. - Participants will return to the Clinical Center the next morning for 4 hours. They will have blood drawn. They will eat breakfast and then repeat blood draws 2.5 hours later. They will have a urine test. - Blood and urine tests will be done at the end of the fast and after the meals to confirm that the participant fasted for the full 24-hour period. - Participants will have lung function tests and exhaled gas measurements. A machine will measure the volume of air they can breathe out. Some gases in the breath increase with inflammation. Participants will breathe into a machine that analyzes the gases in their breath.
The objective of this pivotal study is to evaluate the relative bioavailability of Synflutide HFA 250/25 Inhaler and SeretideTM 250 EvohalerTM in healthy volunteers with charcoal block.

The purpose of this study is to demonstrate the effectiveness of bronchial thermoplasty in a severe asthmatic population with frequent exacerbations. This will be a single center randomized and controlled study. Thirty subjects with severe asthma (Gina 4 and 5) with frequent severe exacerbations (four or more bursts of systemic corticosteroids >3 days each in the previous year) will be randomized 1:1 to either the thermoplasty group (bronchial thermoplasty and medical management) or control group (medical management only).
The aim of this study is to assess the knowledge, the attitudes and the practices of parents of asthmatic children.
The World Health Organisation predicts that lung disease will be the World's third largest killer in the future. This research project is looking to see whether the concept of a "home hospital" using the latest gadgets and iPad technology, can help patients stay well and out of hospital. Portsmouth Hospitals Trust is collaborating with a Company based in the United Kingdom (UK) who has developed a test to predict when people with lung diseases, such as; asthma, COPD and bronchiectasis, who regularly have chest infections, are about to become poorly with another infection - a form of early warning system. The investigators hope that the test will eventually be able to be used by the patient at home daily, to help self-manage their condition. The test measures whether bacteria are present, in sputum, and in what quantity. This information can be used by the patient's healthcare team to consider providing treatment earlier, thus controlling the infection sooner and reducing the patient's symptoms so that patients can stay at home rather than being regularly admitted to hospital. Part of this "early warning system" that has been developed by the UK Company includes the daily measurement of a number of indicators of health. These are usually only measured in hospital or by a General Practitioner, but new devices have been made that are simple enough for everyone to use at home. The investigators will include 30 participants, with non-Cystic Fibrosis (CF) chronic respiratory conditions who will be asked to take daily measurements of their blood pressure, temperature, weight and how well their heart and lungs are working with easy-to-use devices. They will also measure their physically activity with an activity tracker and report their wellness and whether they have taken medication daily. Participants will also be asked to collect a sample of sputum and urine each morning. Taking the samples and measurements should only take between 5-15 minutes each day to carry out. The sputum and urine will be tested at the hospital and will be recorded and analysed, so that the researchers can learn what happens well before a person with these conditions falls sick and needs hospitalisation.
Pulmonary arteriovenous malformations (PAVMs) are a rare vascular condition affecting the lungs. PAVMs lead to low blood oxygen levels, yet are very well tolerated by patients. This study will examine the exercise capacity of PAVM patients using formal cardiopulmonary exercise tests performed on a stationary bicycle, and whether this is affected by the presence of concurrent airflow obstruction, such as due to asthma.
The objective of this randomized control trial is to investigate the efficacy of an adjunct positive airway pressure (PAP) nebulizer device known as "AccuPAP" in the treatment of moderate-severity acute asthma exacerbations in children ages 6 - 17 years in comparison with an institutional standard continuous dual-therapy nebulizer treatment. The investigators main goal, more specifically, is to determine if the additional positive airway pressure provided by the AccuPAP device when used in treating children with moderate-severity asthma exacerbations provides a more optimal delivery of bronchodilator therapy when compared to institutional standard protocol nebulizer delivery mask which does not employ the use of positive airway pressure in medication delivery. The investigators have determined that the change in a study-validated Acute Asthma Intensity Research Score (AAIRS) which will be considered statistically significant for a patient is 2 points or greater after the first treatment has been completed.
Many studies have investigated the efficacy and safety of Intravenous magnesium sulfate and inhaled steroids in addition to the standard treatment for patients with severe asthma attacks. In this 2x2 factorial design blinded randomized study, no interaction of hypothesized treatments is expected.Investigators hypothesize that two doses of intravenous magnesium sulfate,a high dose followed by a (lower) standard dose, will shorten the time to medical readiness for discharge compared to a single standard dose followed by placebo.The second hypothesis is that nebulized inhaled budesonide will be superior to placebo.
