The present invention relates to RNAi agents, e.g., double-stranded RNAi agents, targeting the hepatitis B virus (HBV) genome, and methods of using such RNAi agents to inhibit expression of one or more HBV genes and methods of treating subjects having an HBV infection and/or HBV-associated disorder, e.g., chronic hepatitis B infection.本發明係有關靶向B型肝炎病毒(HBV)基因組之RNAi劑,例如:雙股RNAi劑,及使用此等RNAi劑抑制一或多種HBV基因表現之方法及治療患有HBV感染及/或HBV-相關病症(例如:慢性B型肝炎感染)之個體之方法。
