About this study

Official title: Sero-epidemiological Study of the SARS-CoV-2 Virus in France: Constitution of a Collection of Human Biological Samples

On January 2020, the discovery of a new coronavirus (SARS-CoV-2) was officially announced by the Chinese health authorities and the World Health Organization (WHO). Its complete genome was sequenced by the laboratory of respiratory infection viruses at the Institut Pasteur on 29 January 2020 in France. This will allow the identification of antigenic structures involved in the immune response and the development of serological diagnostic tests.

Many questions are being asked about this new virus and the infection it causes, including questions about the percentage of asymptomatic and pauci-symptomatic forms. Serological studies can provide answers to these questions. There is no serological test for SARS-COV-2 yet, but the laboratory of respiratory infection viruses at the Institut Pasteur is working on its development.

This study proposes to carry out a collection of samples taken from subjects who travelled to China before the epidemic outbreak or suspected of being infected with SARS-CoV-2.

As soon as it is available, serology will be performed on the collected samples.

Read the detailed description

On January 2020, the discovery of a new coronavirus (SARS-CoV-2) was officially announced by the Chinese health authorities and the World Health Organization (WHO). This new virus is presented as the causative agent of pneumonias. Its complete genome was sequenced by the laboratory of respiratory infection viruses at the Institut Pasteur on 29 January 2020 in France. This will allow the identification of antigenic structures involved in the immune response and the development of serological diagnostic tests.

Many questions are being asked about this new virus and the infection it causes, including questions about the transition from animal to human occur, the beginning of viral circulation in humans, the period of contagiousness, the percentage of asymptomatic and pauci-symptomatic forms. Serological studies can provide answers to these questions. There is no serological test for SARS-COV-2 yet, but the laboratory of respiratory infection viruses at the Institut Pasteur is working on its development.

This study proposes to carry out a collection of samples taken from subjects who travelled to China before the epidemic outbreak or suspected of being infected with SARS-CoV-2.

As soon as it is available, serology will be performed on the collected samples.

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 7 Jul 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 21 sites 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?

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?

Presence of specific anti-SARS-CoV-2 antibodies in the different study groups. (time frame: One year). 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 NCT04325646, which also lists 2 linked publications.

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?
