Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • Healthy volunteers accepted
  • Adult, Older adult

Study population: Hospitalized patients

Who may be able to join

  • Age 18 years and above;
  • Able to give informed consent;
  • Clinically tested for SARS-CoV-2 (as completed by standard laboratory testing e.g. RT-PCR) and with a positive result and clinical features in keeping with COVID-19 illness. The control group will be patients with a negative RT-PCR COVID-19 test and without any clinical features to suggest COVID-19 illness. In addition, the control group should have NO known or current features of respiratory infection, COPD, asthma, interstitial lung disease, other respiratory inflammatory conditions or lung cancer.
  • Able to provide a breath sample (as based on clinical judgement).

Who cannot join

  • none

About this study

To assess if TSLP expression by airway epithelial cells following COVID-19 infection regulates viral load and disease severity.

Read the detailed description

The study aim is to determine the relationship between COVID-19 infection and epithelial cell expression of TSLP. Two cohorts will be used. Cohort One will include 100 hospitalized patients with Covid-19, and 100 hospitalized patients without Covid-19. Cohort 2 will include mild/moderate asthmatics and healthy controls with bio-banked biopsy material used from donors who have previously consented for samples to be used for future research.

Study groupRoleWhat they receive
Hospitalized patients100 patients hospitalized with Covid-19, and 100 hospitalized controls without Covid-19
Mild/Moderate asthma and health controls20 asthmatic patients, 10 patients with asthma and allergic rhinitis, and 5 healthy controls.

What is being measured

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

  1. TSLP expression in nasal epithelium

    Compare the level of TSLP expression in nasal epithelium in patients with and without COVID-19 infection

    Measured: Through study completion, an average of 1 year

Secondary outcomes (3)
  1. TSLP expression in endobronchial biopsies

    Epithelial cell expression (protein staining) of TSLP in endobronchial biopsy tissue of asthmatic patients versus normal controls.

    Measured: Baseline

  2. IL-33 expression in endobronchial biopsies

    Epithelial cell expression (protein staining) of IL-33 in endobronchial biopsy tissue of asthmatic patients versus normal controls.

    Measured: Baseline

  3. ACE-2 receptor expression in endobronchial biopsies

    Epithelial cell expression (protein staining) of ACE-2 receptor in endobronchial biopsy tissue of asthmatic patients versus normal controls.

    Measured: Baseline

Questions about this trial

What is this clinical trial studying?

An observational study of Asthma and Covid19, run by McMaster University 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 4 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: status not confirmed, as of the sponsor's last update on 8 Mar 2021. 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. 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?

Results are not available in the source record.

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

Contact Gail Gauvreau, PhD (9055259140 ext. 22791, gauvreau@mcmaster.ca), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

TSLP expression in nasal epithelium (time frame: Through study completion, an average of 1 year). 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 8 Mar 2021.
