About

The FXReservoir#1 study (NCT03618862) showed that certain FXR ligands reactivate latent viruses in the reservoir circulating in all HIV+ patients tested. These molecules appear as latency reversal agents (LRA) of silent viruses of the HIV reservoir. They can be part of the strategy to eradicate this reservoir, responsible for recurrences of the infection when combined anti-retroviral treatments are stopped.

Two effective leads have been identified on in vitro tests and on ex vivo reactivation using FXReservoir#1. These molecules come from a chemical library of FXR ligands developed by the Inserm team behind the discovery of a role for FXR in viral infections.

A first series of optimized molecules derived from these leads has been synthesized; these molecules, after screening on viral and ADMET (Absorption, Distribution, Metabolisme, Excretion and Toxicity) in vitro tests, must be tested ex vivo on CD4+ lymphocytes from the circulating peripheral reservoir of HIV+ patients in order to select the best molecules with LRA activity. This step is essential before considering the clinical development of an LRA.
