Efficiency of Antagonist Drugs of the Cellular Transcriptomic Signature of Influenza A Virus Infection.

• Status: Recruiting
• Trial end date: 2023-12-01
• Target enrollment: 0
• Participant gender: All

Summary

The aim of this study is to evaluate the possibility to repropose marketed drugs as antiviral ones, based on their ability to reverse the transcriptomic signature of the infected cells. This strategy has to be considered is the context of emerging viral diseases and of increase of resistance to antivirals. Concerning infection by Influenza viruses, the main drugs were identified and evaluated on in vitro and in vivo models: diltiazem. Therefore, it will be assess the efficacy of these the drug, compared to placebo, to treat severe flu.
