IL SR0716

Feline infectious peritonitis (FIP) is a viral disease in cats caused by certain strains of feline coronavirus that is progressive and almost always fatal without treatment.

Two drugs, remdesivir (GS-5734) and GS-441524 (a remdesivir metabolite), demonstrated cure rates between 80% and 100% in laboratory and naturally infected cats, with GS-441524 showing promise for treating the effusive form of FIP.

GS-441524 is currently not FDA-approved, and products available from various sources vary widely in drug concentration accuracy and purity.

The drug developer did not seek FDA approval for GS-441524 as a veterinary drug, fearing negative effects could hinder approval of remdesivir for human COVID-19 treatment.

Illinois Senate urges the FDA to approve both GS-441524 and remdesivir to treat feline infectious peritonitis in cats.
