About this study

Official title: Does a Lipophilic Steroid Inhaled After an Early Allergic Reaction Affect the Late Reaction?

The investigators propose a 3-treatment, placebo-controlled, double-dummy, double-blinded, randomized, crossover study in which single doses of placebo, will be compared to Fluticasone propionate (Flovent Diskus) 250 mcg and budesonide 400 mcg administered after allergen challenge, at cessation of the early allergic reaction (at 20% fall in FEV1 from post-allergen peak)

Read the detailed description

The aim of this pilot study is to evaluate whether fluticasone propionate affects the late allergic reaction after a single dose post-allergen challenge administered following cessation of the early allergic reaction.

Six subjects with mild asthma will be asked to volunteer for the study.The diagnosis of asthma will be and includes the presence of variable airflow limitation and AHR (PC20 methacholine < 16 mg/mL). Subjects will be asked to participate if they demonstrate an allergen-induced early and late asthmatic response of at least 20% and 15% reduction in FEV1, respectively.

The study will consist of 4 periods, composed of a screening allergen period with 3 subsequent allergen challenge/treatment periods. Each period will be separated with a washout of at least 2 weeks. Subjects who demonstrate a dual asthmatic response in the screening period will be selected for randomization to treatment.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The Magnitude of the Early Asthmatic Response, Expressed as a Percentage Change in FEV1.

    Measured: Before inhalation 3 hours

  2. The Magnitude of the Late Asthmatic Response, Expressed as a Percentage Change in FEV1.

    Measured: 7 hours after challenge

Secondary outcomes (3)
  1. The Magnitude of Allergen-induced Airway Hyperresponsiveness (Methacholine PC20) and Inflammation (Sputum Eosinophils).

    Measured: Before inhalation both evaluations (0 hours)

  2. The Magnitude of Allergen-induced Airway Hyperresponsiveness (Methacholine PC20) and Inflammation (Sputum Eosinophils)

    Measured: sputum @ 7 hours

  3. The Magnitude of Allergen-induced Airway Hyperresponsiveness (Methacholine PC20) and Inflammation (Sputum Eosinophils)

    Measured: 24 hours methacholine and sputum

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Fluticasone propionate (Flovent Diskus) 250 mcg and budesonide 400 mcg in people with Mild Intermittent Asthma, run by Hamilton Health Sciences Corporation at 1 site in Canada.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 29 May 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 15 May 2015). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The Magnitude of the Early Asthmatic Response, Expressed as a Percentage Change in FEV1. (time frame: Before inhalation 3 hours). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00716963, which also lists 13 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 May 2018.
