We modeled the viral dynamics of 13 untreated patients infected with SARS-CoV-2 to infer viral growth parameters and predict the effects of antiviral treatments. In order to reduce peak viral load by more than 2 logs, drug efficacy needs to be greater than 80% if treatment is administered after symptom onset; an efficacy of 50% could be sufficient if treatment is initiated before symptom onset. Given their pharmacokinetic/pharmacodynamic properties, current investigated drugs may be in a range of 20-70% efficacy. They may help control virus if administered very early, but may not have a major effect in severe patients.

Development of new antiviral treatments against SARS-CoV2 in collaboration with the Center for Infection & Immunity of Lille (CIIL) and the Institut Pasteur de Lille.

Jean Dubuisson's team at the Center for Infection and Immunity of Lille (CIIL) together with the Drug Discovery Center of Benoit Déprez on the campus of the Institut Pasteur de Lille and the VirPath team at the Centre International de Recherche en Infectiologie (CIRI) in Lyon join their complementary expertise and technologies for development of new antiviral treatments and fight more efficiently against SARS-CoV-2. VirPath has supplied the Center for Infection and Immunity of Lille with a characterized and sequenced SARS-CoV-2 strain and makes its preclinical models of infection available.

The Lyon healthcare cluster is mobilizing alongside our #VirPath laboratory in its fight against SARS-CoV-2.

The Lyon healthcare cluster is mobilizing alongside our #VirPath laboratory in its fight against SARS-CoV-2. In collaboration with the Hospices Civils de Lyon, the genomic platform ProfileXpert and the companies ViroScan3D and Signia Therapeutics, our laboratory has isolated and characterized by deep sequencing two SARS-CoV-2 viral strains from several patient samples. Our analyses confirm that our SARS-CoV2 viral bank is genetically stable after amplification at both the consensus level and the low-frequency mutation landscape. Sequences have been uploaded to GISAID to contribute to the international program monitoring and studying the SARS-CoV-2.

Glycoflu program aims to develop a new generation of influenza antiviral drugs.


Our VirPath Laboratory, with its technological research Platform VirNext, is partner of the GlycoFlu program which aims to develop a new generation of influenza drugs that could be administered orally (aerosols) with multiple development potentials (human or avian flu) and applications both prophylactic and therapeutic. Launched on January 20, 2020, this program funded by the SATT Linksium Grenoble Alpes, is led by Emeline Richard Millot, winner of the Grand Prize in the I-PhD competition from the Ministry of Higher Education, Research and Innovation in partnership with BPI France, and Eric Samain from CERMAV (CNRS). #influenza #antiviral

Our laboratory VIRPATH is mobilized with the REACTING consortium on the front line against the 2019-n-CoV Coronavirus

We are currently characterizing the virus in several preclinical models of interest with the aim of applying our drug repurposing strategy and thus rapidly proposing a therapeutic solution to be tested in clinic against such new emerging epidemic virus. Signia Therapeutics joins our laboratory in the fight against Coronavirus 2019-n-CoV and announces that two proprietary molecules from its portfolio, already validated for their antiviral properties against MERS-COV and several other human and animal coronaviruses, will be tested against Coronavirus 2019-n-CoV in preclinical models of infection.

VirPath: We are pleased to announce the launch of Cynbiome, a preclinical excellence network on microbiome and infectious diseases. We congratulate the principal investigator Cynbiose, a service company specializing in the development and commercialization of innovative preclinical models.

CYNBIOME is financed by the French government and the Auvergne- Rhône-Alpes region and is supported by The French Public Bank of Investment (Bpifrance).

Our laboratory and our Technological Research Platform VirNext are very proud to be partners of the cynbiome network. We will bring our expertises, OMICS analytic tools and biological materials in the field of infectious diseases to contribute in the development of this ambitious and unique network in EU.
