Ridgeback announced that the US Food and Drug Administration (FDA) has approved the ind application for oral antiviral compound eidd-2801. The FDA's move allows Ridgeback to launch clinical trials of eidd-2801 in humans in the United States.
Eidd-2801 is an oral bioavailable form of highly effective ribonucleoside analogues, which can inhibit the replication of a variety of RNA viruses. The animal studies of two different coronaviruses showed that eidd-2801 could improve lung function, reduce weight loss and reduce the amount of virus in the lung.
Application
EIDD-2801 is the isopropylester prodrug of N4-hydroxycytidine. With improved oral bioavailability in non human primates, it is hydrolyzed in vivo, and distributes into tissues where it becomes the active 5'-triphosphate form. The active drug incorporates into the genome of RNA viruses, leading to an accumulation of mutations known as viral error catastrophe.
