Clinical 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 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.

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).

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	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.	Day: 7
Secondary	Number and percentage of SARS-CoV-2 infection in the selected population tested by reference RT-PCR on saliva	Measured by RT-PCR results.	Day: 7
Secondary	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.	Day: 7
Secondary	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.	Day: 7
Secondary	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.	Day: 7
Secondary	Number of people who have benefited from sensitization and support specifically set up as part of the screening campaign	Measured the screening day.	Day: 7
Secondary	Number of persons cared for by the territorial isolation support cell (CTAI)	Measured the screening day.	Day: 7
Secondary	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.	Day: 7
