NCT ID: NCT03436316 Not yet recruiting - Asthma Clinical Trials

A Study to Evaluate the Safety, Tolerability and Study Drug Absorption to the Blood After Administration of Single Ascending Doses of AZD8154 in Healthy Subjects.

Start date: March 12, 2018
Phase: Phase 1
Study type: Interventional

This study will be a Phase 1, first in human (FiH) study, consisting of 3 parts (Part 1, Part 2 and Part 3) in healthy male and female subjects of non-childbearing potential, performed at a single study center. Part 1 of this study will be a randomized, single-blind, placebo-controlled, single ascending dose (SAD) in healthy non-smoking male and female subjects of non-childbearing potential. Six dose levels of AZD8154 are planned to be investigated. Depending on emerging data, 1 to 2 additional dose levels may be added at the discretion of the Sponsor. Furthermore, one dose level will be repeated using the same formulation of AZD8154 but with a larger particle size (Part 1 only). Part 2 of this study will be a single cohort, open-label, crossover study in healthy non-smoking male and female subjects of non-childbearing potential, to compare a single inhaled dose of AZD8154 with a single IV dose of AZD8154. Part 3 of this study will be a single cohort, randomized, double-blind, cross-over study in healthy smoking male and female subjects of non-childbearing potential, to compare the effect of a single dose of AZD8154 to a single dose of placebo in regard to sputum PIP3 fraction.

NCT ID: NCT03435822 Not yet recruiting - Asthma in Children Clinical Trials

Clinical Study on Chinese Children's Asthma Action Plan

Start date: March 1, 2018
Phase: N/A
Study type: Interventional

This study is a multi-center and prospective case-controlled study of children with asthma. The objective of the study is to assess the efficacy of China Children Asthma Action Plan (CCAAP), which is the first asthma action plan for children with asthma in China, in asthma management.

NCT ID: NCT03435237 Not yet recruiting - Severe Asthma Clinical Trials

Phenotyping Asthma for Bronchial Thermoplasty

Start date: April 2018
Phase: N/A
Study type: Observational

This study will evaluate a new imaging technology, called optical coherence tomography (OCT) to examine the asthmatic airways before and after bronchial thermoplasty, which is a new treatment option for severe asthmatic patients. The aim of this study is to learn more about how airways respond to this new treatment. In the future the investigators hope OCT will aid clinicians in the initial assessment, management and long-term follow up of patients receiving bronchial thermoplasty.

NCT ID: NCT03430505 Recruiting - Asthma Clinical Trials

Effects of Noninvasive Ventilation Compared to Salbutamol

Start date: June 10, 2017
Phase: N/A
Study type: Interventional

Asthma is a chronic inflammatory disease characterized by recurrent and reversible episodes of airway obstruction. Drug treatment usually includes inhaled corticosteroids and bronchial dilators, which often do not have adequate adherence. These acute episodes of bronchoconstriction can most often occur with hyperinflation and for decades the mechanisms that lead to hyperinflation have been studied, as well as increasingly modern ways of evaluating and treating these mechanisms. Noninvasive ventilation is increasingly occupying its space as a non-pharmacological resource in the treatment of asthma, initially as an adjunct in an attempt to help medication have its effect reached in the crisis, but this feature has been showing signs of having an even greater action which can even collaborate in reversing the crisis by not only giving time for pharmacological action. Recognizing these potential effects of this widely used resource and understanding its action on lung function and the reversal of exacerbation is part of this scientific process.

NCT ID: NCT03423693 Recruiting - Asthma Clinical Trials

Small Airway Obstruction in Asthma, COPD, ACOS

Start date: January 2016
Phase: N/A
Study type: Observational

This study was designed as retrospective chart review to test our hypothesis whether there are the differences in inflammatory and anti-inflammatory mediators between asthmatic and ACOS patients with small airway obstruction, and COPD

NCT ID: NCT03421730 Recruiting - Wheezing Clinical Trials

A Study of the Pharmacokinetics, Safety and Tolerability of Single Doses of VR647 Inhalation Suspension Administered Using the VR647 Inhalation System in Children With Wheezing, Reactive Airway Disease or Mild Asthma

Start date: December 18, 2017
Phase: Phase 1
Study type: Interventional

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.

NCT ID: NCT03420651 Recruiting - Asthma Clinical Trials

Peak Expiratory Flow Rate for Emergency Department Management of Acute Asthma Exacerbation

Start date: January 19, 2018
Phase: N/A
Study type: Interventional

Patients presenting to the emergency department with acute asthma exacerbation will be assigned to peak-expiratory flow rate (PEFR) guided management and non-PEFR guided management.

NCT ID: NCT03416907 Completed - Asthma Clinical Trials

Informed Consent Formats by Information Preference and Priority

Start date: November 27, 2017
Phase: N/A
Study type: Interventional

This study will test whether different formats of medical informed consent documents can help improve understanding and confidence in decision-making for clinical trials. The study will be primarily run through an online survey.

NCT ID: NCT03414177 Recruiting - Asthma Clinical Trials

Telehealth Enhanced Asthma Management

TEAM
Start date: January 2018
Phase: N/A
Study type: Interventional

This study will conduct a 12-month randomized trial with 84 pediatric patients (aged 6-18 years) with persistent asthma to compare outcomes among patients with follow-up visits managed via telemedicine (TM) vs. in-person (IP) visits.

NCT ID: NCT03406351 Recruiting - Healthy Clinical Trials

Air Pollution, Asthma and Circadian Clocks

APACC
Start date: January 15, 2018
Phase: N/A
Study type: Observational

Societies become increasingly urban - more than half the world's population now lives in cities. Urbanization elevates anthropogenic (man-made) exposure to air pollutants. A clear association exists between exposure to air pollutants and exacerbations (worsening) of pre-existing asthma, incidence of nighttime asthma, difficulties with asthma control and increased disease risk. In 2012, the Public Health Management Corporation's Community Health Data Base estimated that 19.4% of adults in Philadelphia had asthma compared to a national prevalence of 7%. Asthma has a clear temporal signal. A majority of asthma patients, up to 75%, reports nighttime awakenings due to worsened cough, wheeze and dyspnea. This time-of-day-dependent exacerbation of symptoms, coined nocturnal asthma, is associated with poorer disease control, more frequent medication, and higher asthma-related morbidity and mortality. Consequently, several pathophysiological mechanisms proposed for nocturnal asthma relate to circadian clock biology. Lung function oscillates over the course of 24 hours, peaking around noon and reaching its nadir during early morning hours. Concentrations of air pollutants show oscillating patterns in urban settings. In this clinical research study, the investigators start to address how spatiotemporal fluctuations in air pollutants relate to asthma. Mechanistically, the investigators wish to address the hypothesis that microRNAs (miRs) act as interface between asthma phenotypes, circadian clocks and environmental exposure.
