  The disclosure relates to compositions comprising a HBV RNAi agent. In some embodiments, the HBV RNAi agent comprises a sense and an anti-sense strand, each strand being an 18-mer and the strands together forming a blunt-ended duplex, wherein the 3′ end of at least one strand terminates in a phosphate or modified internucleoside linker and further comprises, in 5′ to 3′ order: a spacer; a second phosphate or modified internucleoside linker; and a 3′ end cap. In some embodiments, the 3′ end of both the sense and anti-sense strand further comprise, in 5′ to 3′ order: a spacer; a second phosphate or modified internucleoside linker; and a 3′ end cap. The two strands can have the same or different spacers, phosphates or modified internucleoside linkers, and/or 3′ end caps. The strands can be ribonucleotides, or, optionally, one or more nucleotide can be modified or substituted. Optionally, at least one nucleotide comprises a modified internucleoside linker. Optionally, the RNAi agent can be modified on one or both 5′ end. Optionally, the sense strand can comprise a 5′ end cap which reduces the amount of the RNA interference mediated by this strand. Optionally, the RNAi agent is attached to a ligand. This format can be used to devise RNAi agents to a variety of different targets and sequences. The disclosure also relates to processes for making such compositions, and methods and uses of such compositions, e.g., to mediate RNA interference. The disclosure also pertains to methods of treating, ameliorating and preventing HBV in a patient involving the step of administering to the patient a therapeutic amount of a HBV RNAi agent.

  该披露涉及包含HBV RNAi药剂的组合物。在某些实施例中，HBV RNAi药剂包括一个正义链和一个反义链，每个链都是18个核苷酸长，并且这些链一起形成一个带有钝端的双链，其中至少一个链的3'端终止于磷酸酯或修饰的核苷酸间连接物，并且进一步包括，按照5'到3'的顺序：一个间隔物；第二个磷酸酯或修饰的核苷酸间连接物；和一个3'端帽。在某些实施例中，正义链和反义链的3'端进一步包括，按照5'到3'的顺序：一个间隔物；第二个磷酸酯或修饰的核苷酸间连接物；和一个3'端帽。这两个链可以具有相同或不同的间隔物、磷酸酯或修饰的核苷酸间连接物，和/或3'端帽。这些链可以是核糖核苷酸，或者，可选地，一个或多个核苷酸可以被修饰或替代。可选地，至少一个核苷酸包括一个修饰的核苷酸间连接物。可选地，RNAi药剂可以在一个或两个5'端上被修饰。可选地，正义链可以包括减少由该链介导的RNA干扰量的5'端帽。可选地，RNAi药剂附着在一个配体上。这种格式可以用来设计针对各种不同靶标和序列的RNAi药剂。该披露还涉及制备这种组合物的方法，以及这种组合物的方法和用途，例如，用于介导RNA干扰。该披露还涉及涉及将治疗量的HBV RNAi药剂给患者的步骤来治疗、改善和预防患者体内的HBV的方法。
