Condition(s) targeted: Asthma

Intervention: Ciclesonide (Drug); Placebo (Drug)

Phase: Phase 4

Status: Completed

Sponsored by: University of Nottingham

Official(s) and/or principal investigator(s):
Tim Harrison, Principal Investigator, Affiliation: University of Nottingham
Ian Pavord, Principal Investigator, Affiliation: University Hospitals, Leicester

Summary

The purpose of this study is to determine whether an inhaled steroid with a small particle size can be an additional treatment option in patients with refractory eosinophilic asthma.

Clinical Details

Official title: Small Particle Inhaled Steroids in Refractory Steroid-responsive Asthma

Study design: Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Primary Purpose: Treatment

Primary outcome: Change in sputum eosinophil count over the trial period

Secondary outcome:

Change in alveolar nitric oxide level over the trial period

Change in bronchial nitric oxide level

Change in prebronchodilator FEV1

Change in Juniper Asthma Control Questionnaire (ACQ) score

Change in Juniper Asthma Quality of Life Questionnaire (AQLQ) score

Use of oral steroid over the trial period

Number of patients with adverse events as a measure of safety and tolerability

Detailed description: We have identified a group of patients with refractory asthma who have ongoing eosinophilic airway inflammation despite high dose inhaled corticosteroids. Traditional inhaled steroids have a relatively proximal airway distribution which may lead to inadequate treatment of the distal airways. We aim to demonstrate that a steroid inhaler with a smaller particle size which targets the distal airways can be a useful additional treatment option in this group of patients.
