Trial summary

The virological diagnosis of SARS-CoV-2 infection is pivotal for the control of the outbreak by large screening of a- or pauci-symptomatic subjects. Despite nasopharyngeal swabbing tested by RT-PCR is considered as the gold standard, new strategies based on self-samples are considered as valuable alternatives because… Read more about this study

About this study

Official title: Comparison of Strategies Based on RT-PCR or Antigenic Test for the Screening of SARS-CoV-2 Infection in General Population Using Self-samples (COVID-19).

The virological diagnosis of SARS-CoV-2 infection is pivotal for the control of the outbreak by large screening of a- or pauci-symptomatic subjects. Despite nasopharyngeal swabbing tested by RT-PCR is considered as the gold standard, new strategies based on self-samples are considered as valuable alternatives because of their non-invasiveness and ability to be performed in the absence healthcare worker, especially when the subject is asymptomatic and needs to be tested repetitively. The aim of the present project is to evaluate two strategies both based on self-samples: (i) a saliva sample combined to an anterior nare self-swabbing tested by antigenic test versus (ii) a saliva sample tested by RT-PCR. The comparison will be performed during a mass screening of the population of the city of Saint-Etienne (170000 inhabitants), France. The sensitivity of the rapid antigenic test will be evaluated in comparison to that of RT-PCR considered as gold standard.

Read the detailed description

The main objective is to evaluate the performance of a strategy for screening for CoV-2-SARS infection that would combine 1) a salivary self-sample with an anterior nasal swab and 2) a diagnostic antigenic test, in comparison with the reference salivary RT-PCR technique recently validated by National Authority for Health (HAS).

Being tested
saliva sample combined to an anterior nare self-swabbing (Self-samples), saliva sample (Self-sample), Survey of SARS-COV-19 knowledge, Survey of acceptability of the different self-samples.

What is being measured

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

  1. Positivity of self-samples combining saliva and anterior nare specimens tested by rapid antigenic test compared to saliva tested by RT-PCR (gold-standard).

    Measured by antigenic test results and RT-PCR results.

    Measured: Day: 7

Secondary outcomes (7)
  1. Number and percentage of SARS-CoV-2 infection in the selected population tested by reference RT-PCR on saliva

    Measured by RT-PCR results.

    Measured: Day: 7

  2. Number and percentage of the circulation of different variants of interest of SARS-CoV-2 viruses in the tested population

    Measured by RT-PCR results.

    Measured: Day: 7

  3. Evaluate the acceptability (pain, discomfort, speed of execution) of self-samples according to age and socio-professional categories

    Measured by survey of acceptability of the different self-samples results.

    Measured: Day: 7

  4. Evaluate the cost-effectiveness ratio of the new strategy by comparison to the gold standard (RT-PCR on saliva)

    Measured by number of test performed and performances of self-samples combining saliva and anterior nare specimens tested by rapid antigenic test compared to saliva tested by RT-PCR.

    Measured: Day: 7

  5. Number of people who have benefited from sensitization and support specifically set up as part of the screening campaign

    Measured the screening day.

    Measured: Day: 7

  6. Number of persons cared for by the territorial isolation support cell (CTAI)

    Measured the screening day.

    Measured: Day: 7

  7. Health literacy questionnaire

    It is a questionnaire with items on the transmission of the virus and barrier gestures, adherence to barrier gestures, modalities of isolation in case of positivity and motivations for participating in this screening campaign.

    Measured: Day: 7

Questions about this trial

What is this clinical trial studying?

A study testing saliva sample combined to an anterior nare self-swabbing (Self-samples), saliva sample (Self-sample) and Survey of SARS-COV-19 knowledge in people with SARS-CoV Infection, run by Centre Hospitalier Universitaire de Saint Etienne at 1 site in France.

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 2 inclusion and 3 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 6 May 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 France. 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?

What does the primary outcome measure?

Positivity of self-samples combining saliva and anterior nare specimens tested by rapid antigenic test compared to saliva tested by RT-PCR (gold-standard). (time frame: Day: 7). 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 NCT04859023, 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?
