What is being measured

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

  1. Airway inflammation

    Bronchial airway inflammation. Differential cell count will be performed on sputum samples, determining eosinophilic (>3% eosinophils, <61% neutrophils), neutrophilic (<3% eosinophils and >61% neutrophils), pauci-granulocytic (<3% eosinophils and <61% neutrophils) and mixed granulocytic airway inflammation (>3% eosinophils and >61% neutrophils).

    Measured: Day 1 and after 6 months

  2. Change in Forced Expiratory Volume in 1 seconds (FEV1)

    The forced expiratory Volume in 1 second will be measured using spirometry

    Measured: Day 1 and after 6 months

Secondary outcomes (4)
  1. Cytokine pattern in the airways

    Cytokines concentrations (pg/ml) will also be determined in sputum supernatant using a U-plex assay.

    Measured: Day 1 and after 6 months

  2. Cytokine pattern in the bloodstream

    Cytokines concentrations (pg/ml) will also be determined in serum using a U-plex assay.

    Measured: Day 1 and after 6 months

  3. Change in asthma control

    Asthma control will be determined using the Asthma Control Questionnaire (ACQ-6), including 6 questions. Each question will be scored from 0-6 and added together. This final score will be divided by the number of questions. If ACQ-6 < 0.75 = controlled asthma, ACQ-6 from 0.75-1.5 = partly controlled asthma and ACQ-6 > 1.5 = uncontrolled asthma.

    Measured: Day 1 and after 6 months

  4. Biomarkers for airway inflammation

    Fraction exhaled Nitric Oxid (FeNO) will be used as biomarker for eosinophilic airway inflammation. FeNO < 25 ppb = eosinophilic inflammation less likely, FeNO between 25 and 50 ppm = need further interpretation with additional clinical information, FeNO > 50 ppm = indication of eosinophilic airway inflammation (according to the American Thoracic Society guidelines)

    Measured: Day 1 and after 6 months

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Mepolizumab Injection [Nucala] in people with Asthma, run by KU Leuven.

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 5 inclusion and 1 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 2 Jun 2020. Status can change between updates, so confirm with the study contact before making plans.

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.

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?

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?

Airway inflammation (time frame: Day 1 and after 6 months). 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?
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 2 Jun 2020.
