Description: Inarigivir, also known as ORI-9020 and SB-9000, is a novel dinucleotide, evaluated in transgenic mice expressing hepatitis B virus (HBV), significantly reduced liver HBV DNA (P </= 0.001). Levels of HBeAg and HBsAg in serum and of HBcAg in liver were not affected by treatment. A minimal effective dosage was determined to be between 1.6 and 0.5 mg/kg of body weight/day, which was similar to that observed for adefovir dipivoxil.
