About this study

Official title: A Prospective, Epidemiological, Cohort Study to Assess the Feasibility of Screening Healthy Asymptomatic Workers for the Presence of SARS-CoV-2 by Pharyngeal Swaps and Serology at Baseline, Day 21 and Day 40

This is a prospective, epidemiological, cohort study to assess the feasibility of screening healthy asymptomatic workers for the presence of severe acute respiratory syndrome SARS-CoV-2 by pharyngeal swaps and serology at baseline, day 21 and day 40.

Read the detailed description

This study has been designed to assess the feasibility of screening asymptomatic workers and to investigate the extent of infection, as determined by pharyngeal swaps analysis and immune response against the virus and virus specific CD4+ and CD8+ T-cell analysis. Furthermore, the extent to which virus-specific CD4+ and CD8+ T-cells are induced is investigated as well as the persistence of virus-specific memory CD4+ and CD8+ T-cells -especially in asymptomatic infected persons.

In total, approximately up to 500 workers will be enrolled into the trial to have 450 evaluable subjects at the end of the study. There will be three individual cohorts of workers working in different departments: workers from the production area (cohort 1), workers from the laboratory area (cohort 2) and workers working in other areas (cohort 3).

The fraction of asymptomatic or subclinical infections should be determined as well as the kinetics of the immune responses. For each timepoint the difference between the cohorts is investigated. This study also aims to evaluate the impact of sanitary and preventive measures taken within the company during the pandemic situation.

Epidemiological exposure data and biological samples will be systematically collected. The present study is being conducted in line with World Health Organization recommendations to help understanding the epidemiology of SARS-Cov-2.

What is being measured

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

  1. Immune responses to components of SARS-Cov-2

    Evaluation of immune responses to components of SARS-CoV-2 as well as evaluation of Swab for the presence of SARS-CoV-2 by PCR. Determination of the difference between the study groups in anti-SARS-CoV 2 seropositivity status. Analysis of trends in CD4/CD8 concentrations over time and correlation with immunoglobulin G (IgG) Levels and new assay evaluation.

    Measured: up to visit 3 (day 40)

  2. Swabs for the presence of SARSCoV-2

    Evaluation of Swab for the presence of SARS-CoV-2 by PCR and determination of the difference between the study groups in anti-SARS-CoV 2 seropositivity status.

    Measured: up to visit 3 (day 40)

Secondary outcomes (1)
  1. Difference between the study groups in anti-SARS-CoV 2 seropositivity status

Questions about this trial

What is this clinical trial studying?

An observational study of COVID-19, run by Miltenyi Biomedicine GmbH at 1 site in Germany.

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 14 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 25 May 2022. 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 Germany. 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?

Immune responses to components of SARS-Cov-2 (time frame: up to visit 3 (day 40)). 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 25 May 2022.
