RG7795 (previously ANA773) is an antiviral drug candidate that as of 2015 had been in Phase II trials in hepatitis B.[1] It is an orally-available prodrug of isatoribine,[2] that was under development by Anadys Pharmaceuticals when it was acquired by Roche in 2011.[3] Its active metabolite is an agonist of TLR7; activation of TLR7 causes secretion of endogenous type 1 interferons, which have antiviral activity.[2]

Chemical structure of isatoribine

As of 2021, development of RG7795 appears to be discontinued.[4]
