About this study

Official title: The Feasibility and Diagnostic Value of New Point-of-care Instruments for Breath Analysis in Children With Asthma, Cystic Fibrosis (CF), and Healthy Controls

In this study new hand-held devices for measuring exhaled breath will be tested in children with asthma, CF, and healthy controls. Main objectives will be feasibility and discriminative value of these techniques.

Read the detailed description

Rationale: Assessment of volatile organic compounds (VOCs) is a new recently developed non-invasive technique to assess airway inflammation. The non-invasive character makes it highly suitable for use in (preschool) children. However, the analysis of VOCs by gas chromatography mass spectrometry technique (GC-MS), the gold standard, is expensive and time consuming. Therefore, new hand-held devices (such as electronic Noses (eNoses) and Ion Mobility Spectrometer techniques) have been developed. However, these new point-of-care instruments have not been studied in children.

Objectives: 1) To test whether new point-of-care instruments for the measurement of VOCs in exhaled breath are feasible for use in children aged 6 to 16 years; 2) To explore whether these techniques can differentiate between healthy children, asthmatic children and children with Cystic Fibrosis (CF).

Study design: Cross-sectional study design. Several VOCs tests will be performed in all participants.Besides, fraction of exhaled nitric oxide (FeNO) and inflammatory markers in exhaled breath condensate (EBC) will be measured.

Study population: Three groups of children aged 6 to 16 years: 20 healthy children, 20 children with doctor's diagnosed asthma, 20 children with CF.

Main study parameters/endpoints: Each technique will be evaluated for its use and feasibility in children. For each technique, VOC profiles between study groups will be evaluated for its discriminative power.

What is being measured

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

  1. Number of participants with adverse events directly related to the various point-of-care tests used

    Any adverse event of any kind will be noted. Furthermore, each participant will be asked whether the test was easy to perform. This question can be answered on a 5-point scale (0=totally agree that test was easy to perform, 4= totally disagree that test was easy to perform)

    Measured: Questionnaire will be done directly after specific test (1 day). No long term (S)AE is expected and measurement of each test is only performed once.

Secondary outcomes (4)
  1. Sensitivity and Specificity of new point-of-care Aeonose eNose in diagnosing asthma.

    Aeonose eNose measurements will be analysed by in house software program (Aethena) developed by eNose company (Zutphen, Netherlands). To test sensitivity and specificity, first an area under the receiver operating curve must be calculated with the aforementioned software program. Hereafter sensitivity and specificity of the eNose can be calculated.

    Measured: Measurements will be analysed within 6 to 12 months

  2. Sensitivity and Specificity of new point-of-care Aeonose eNose in diagnosing cystic fibrosis.

    Aeonose eNose measurements will be analysed by in house software program (Aethena) developed by eNose company (Zutphen, Netherlands). To test sensitivity and specificity, first an area under the receiver operating curve must be calculated with the aforementioned software program. Hereafter sensitivity and specificity of the eNose can be calculated.

    Measured: Measurements will be analysed within 6 to 12 months

  3. Sensitivity and Specificity of Ion Mobility Spectrometry in diagnosing asthma.

    IMS measurements will be analysed by software program developed for using IMS data (Visual Now, Ganshorn, Dortmund, Germany). By IMS different VOCs peaks are generated. By using the aforementioned software, these peaks can be analysed and sensitivity and specificity between asthma and healthy children can be calculated.

    Measured: Measurements will be analysed within 6 to 12 months

  4. Sensitivity and Specificity of Ion Mobility Spectrometry in diagnosing cystic fibrosis.

    IMS measurements will be analysed by software program developed for using IMS data (Visual Now, Ganshorn, Dortmund, Germany). By IMS different VOCs peaks are generated. By using the aforementioned software, these peaks can be analysed and sensitivity and specificity between CF and healthy children can be calculated.

Questions about this trial

What is this clinical trial studying?

An observational study of Asthma and Cystic Fibrosis, run by Maastricht University Medical Center at 1 site in Netherlands.

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 4 inclusion and 6 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 19 Dec 2017. 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 Netherlands. 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Number of participants with adverse events directly related to the various point-of-care tests used (time frame: Questionnaire will be done directly after specific test (1 day). No long term (S)AE is expected and measurement of each test is only performed once.). 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 NCT03377686, which also lists 1 linked publication.

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 19 Dec 2017.
