A Study of the Pharmacokinetics, Safety and Tolerability of Single Doses of VR647 Inhalation Suspension...

WheezingReactive Airway Disease1 more

The primary objective of this study is to evaluate budesonide levels in the blood following inhalation of single doses of VR647 Inhalation Suspension in children with wheezing, reactive airway disease or mild asthma using a nebulizer, the VR647 Inhalation System. Secondary objectives include the evaluation of the safety and tolerability of VR647 Inhalation Suspension administered using the VR647 Inhalation System. The study consists of four visits; a screening visit (Visit 1), two dosing days (Visits 2 and 3) and a follow-up visit (Visit 4). On each dosing day a single dose of treatment will be administered. Treatment allocation at Visits 2 and 3 is determined by a balanced incomplete block design.

Azithromycin to Prevent Wheezing Following Severe Respiratory Syncytial Virus (RSV) Bronchiolitis...

RSV Bronchiolitis

This trial is a proof-of-concept pilot study aim to investigate the biologic and clinical effects of early azithromycin treatment in children hospitalized with Respiratory Syncytial Virus (RSV) bronchiolitis. HYPOTHESES In infants hospitalized with RSV bronchiolitis, azithromycin therapy (compared to placebo) will result in: Decreased concentrations of inflammatory mediators (IL-8 as primary outcome) in serum and nasal wash measured on day 8 after randomization. A smaller proportion of participants with recurrent (≥2) wheezing episodes during weeks 3-52 following randomization.

CARE Network Maintenance Versus Intermittent Inhaled Steroids in Wheezing Toddlers (MIST)

Asthma

Asthma affects about 4 million children in the United States and is a leading cause of hospitalizations and school absenteeism. Continuous wheezing in very young children may develop into asthma. Low doses of inhaled corticosteroids (ICS) are commonly prescribed to treat children with particularly bad wheezing episodes. This study will compare the safety and effectiveness of low doses of ICS taken daily versus higher doses of ICS taken only during respiratory tract illnesses for toddlers with continuous wheezing or coughing illnesses.

Treatment of Preschool Children With Upper Respiratory Tract Illnesses Using Azythromycin and Lower...

AsthmaWheezing

This protocol is comprised of two separate, but linked, clinical trials for treating preschool-aged children with recurrent severe episodes of wheezing. The first study (APRIL) will try to prevent wheezing illness from developing using azithromycin. If a wheezing illness does occur, the second trial (OCELOT) will try to decrease the severity of symptoms using oral corticosteroids.

Efficacy of Intermittent Tiotropium in Early Childhood Wheezing

Wheezy BronchitisAsthmatic Bronchitis2 more

This study evaluates the effect of intermittent tiotropium bromide and salbutamol as needed versus intermittent fluticasone propionate and salbutamol as needed, or solely, salbutamol as needed on episode-free days in infants and toddlers with recurrent episodes of wheeze and/or shortness of breath.

Epinephrine Inhalation Aerosol USP, a HFA-MDI Study for Assessment of Pharmacokinetics

AsthmaBronchospasm2 more

This study examines the pharmacokinetic profile of Armstrong's proposed Epinephrine Inhalation Aerosol USP, an HFA-MDI (E004), using a stable isotope deuterium-labeled epinephrine (epinephrine-d3) to differentiate the administered drug from the endogenous epinephrine, in healthy male and female adult volunteers. The current study is designed for a more thorough evaluation of the E004 Pharmacokinetics. Safety of E004 will also be evaluated, under augmented dose conditions.

Wheeze and Intermittent Treatment

Wheezing

The clinical aim of this trial is to assess whether intermittent montelukast is an effective treatment strategy in preschool wheeze. The mechanisms aim of the trial is to determine whether there is a genetically highly-responsive subgroup of children. In designing this trial the investigators have incorporated several novel aspects. First, parents will be able to adjust the use of oral montelukast to their child's symptoms. This allows the investigators to recruit both "episodic" and "multi trigger" patterns of preschool wheeze - and control for any change in wheeze pattern during the trial. Second, before the investigators issue the trial medication, the investigators will assess children's leukotriene genes, focusing primarily on a gene called ALOX5. This ALOX5 "stratification" step will ensure that an equal number of potentially "treatment-responsive" children receive the active drug (montelukast) and the dummy medicine - and the equal numbers will help the investigators to assess the role of ALOX5. For the trial, the investigators will first recruit 1,300 children with a history of preschool wheeze, then divide them into the group with "responsive" and "less responsive" genes by their ALOX5 status. The investigators will then issue parents with the trial medication; 50% will be given montelukast and 50% will be given dummy medication. Parents will start the trial medication whenever their child develops a cold, and stop the medication when wheeze resolve. Parents will also be able to give the trial medication for wheeze between colds. Over the 12 month trial period, the investigators will assess the number of unscheduled attendances to a medical practitioner for wheeze for each child. At the end of the trial, the investigators will determine whether montelukast is effective then whether there is a difference in response to montelukast between the 2 ALOX5 gene groups. At the same time, the investigators will measure many other genes that may influence response to montelukast, as well as the amount of leukotrienes that are excreted in the urine before and during attacks. Using these results, the investigators will be able to both inform national treatment policy, and develop new concepts on the mechanism of preschool wheeze that will inform the development of new therapies. Since children will continue to receive "normal" inhaled therapy, there are no ethical issues in giving a dummy medicine to half of the 1300 children to be recruited. The study will be the largest trial in wheezy preschool children to date, and may open up genetic testing in preschool wheeze.

Nebulized Beclomethasone Dipropionate Improves Respiratory Lung Function in Preschool Children With...

Wheezing

This is a single-centre, open label study, aiming to evaluate the efficacy of beclomethasone dipropionate applied for 12 weeks with a dose of 400 µg twice a day (total dose 800 µg nebulized), on airway resistance and reactances (measured with Rint and FOT techniques) in children with recurrent wheezing, aged 2-5 years. In addition, clinic score as frequency of symptoms and exacerbations, will be assessed.
