AeroEclipse II Agreement

May 12, 2014 updated by: Sharon Dell, The Hospital for Sick Children

Use of the AeroEclipse II Breath Actuated Nebulizer for the Delivery of Methacholine Chloride Bronchoprovocation Agent: A Pilot Study.

Traditional, continuous-mode nebulizers such as the English-Wright nebulizer are designed to operate continuously with tidal breathing. As inhalation accounts for only about one-third of the respiratory cycle, two-thirds of the continuously produced aerosol is lost to the environment possibly posing a hazard any fellow-patients, family members, or health-care workers in the vicinity. The English-Wright has been the only American Thoracic Society (ATS)recommended device available on the market. Recently Roxon Medi-Tech has announced the discontinuation of the English-Wright nebulizer. For these reasons it is necessary to review the use of other nebulizers such as the AeroEclipse II breath-actuated nebulizer and further validate their performance.

The investigators expect to show equivalence between the AeroEclipse II and the English-Wright nebulizers.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This study would like to determine if the use of the Aeroeclipse II breath actuated nebulizer for the delivery of methacholine chloride bronchoprovocation agent to the lungs results in the same Provocation Concentration PC20 (provocation concentration, or dose that causes a 20% decrease in Forced Expiratory Volume in 1 sec or FEV1) as using the English-Wright nebulizer for the delivery of methacholine chloride bronchoprovocation agent to the lungs.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

10 years to 65 years (Child, Adult, Older Adult)

Accepts Healthy Volunteers

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Asthma Subjects
Device: AeroEclipse II breath-actuated nebulizer
The AeroEclipse II (Trudell Medicinal International, London, ON, Canada) is a breath-actuated nebulizer that allows for the creation of aerosol only in response to the patient's inspiratory flow, resulting in virtually no drug loss to the environment and providing a safer healthcare and patient environment by significantly reducing second-hand drug exposure and the possibility for transmission of viral airborne pathogens.
Device: English-Wright continuous-mode nebulizer
The English-Wright is a continuous-mode nebulizer, designed to operate continuously with tidal breathing, producing an aerosol which is lost to the environment possibly posing a hazard to any fellow-patients, family members, or health-care workers in the vicinity. It is the only device recommended by the American Thoracic Society guidelines that is available on the market and it has recently been discontinued. For these reasons it is necessary to review the use of other nebulizers and validate their performance.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Methacholine inhalation challenge
Time Frame: Visit 1(Day 1)
A methacholine inhalation challenges will be performed at each of the first two visits. At the first clinic visit each subject will be randomly assigned to use either the English-Wright continuous-mode nebulizer, or the AeroEclipse II breath actuated nebulizer. The alternate nebulizer will be used during the second clinic visit. The methacholine concentration producing a 20% decrease in Forced Expiratory Volume in 1 second (PC20) will be measured by way of a standard breathing challenge (the tidal breathing Cockcroft technique)
Visit 1(Day 1)
Methacholine inhalation challenge
Time Frame: Visit 2 (up to 2 weeks)
A methacholine inhalation challenges will be performed at each of the first two visits. At the first clinic visit each subject will be randomly assigned to use either the English-Wright continuous-mode nebulizer, or the AeroEclipse II breath actuated nebulizer. The alternate nebulizer will be used during the second clinic visit. The methacholine concentration producing a 20% decrease in Forced Expiratory Volume in 1 second (PC20) will be measured by way of a standard breathing challenge (the tidal breathing Cockcroft technique)
Visit 2 (up to 2 weeks)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Methacholine challenge - Cumulative Effect
Time Frame: Week 3 +/- 1 week
There exists the possibility that as a result of decreased nebulisation time, we may see some cumulative effect from shortening the time between doubling doses of methacholine. If there is a systematic difference between the English-Wright and the AeroEclipse II nebulizers, it will then be impossible to know if we have calculated the wrong dose or we are seeing a cumulative effect. Therefore we are proposing that the first 10 patients participate in a third visit to look for a cumulative effect.
Week 3 +/- 1 week
