  Described are RNAi agents, compositions that include RNAi agents, and methods for inhibition of a beta-ENaC (SCNN1B) gene. The beta-ENaC RNAi agents and RNAi agent conjugates disclosed herein inhibit the expression of a beta-ENaC gene. Pharmaceutical compositions that include one or more beta-ENaC RNAi agents, optionally with one or more additional therapeutics, are also described. Delivery of the described beta-ENaC RNAi agents to epithelial cells, such as pulmonary epithelial cells, in vivo, provides for inhibition of beta-ENaC gene expression and a reduction in ENaC activity, which can provide a therapeutic benefit to subjects, including human subjects, for the treatment of various diseases including chronic obstructive pulmonary disease (COPD).

  描述了RNAi药剂、包含RNAi药剂的组合物，以及抑制β-ENaC（SCNN1B）基因的方法。本文披露的β-ENaC RNAi药剂和RNAi药剂结合物抑制了β-ENaC基因的表达。还描述了包含一个或多个β-ENaC RNAi药剂的药物组合物，可选地与一个或多个额外治疗药物一起使用。将所述的β-ENaC RNAi药剂传递至上皮细胞，如体内的肺上皮细胞，可实现抑制β-ENaC基因表达和减少ENaC活性，这可以为受试者，包括人类受试者，提供治疗益处，用于治疗包括慢性阻塞性肺疾病（COPD）在内的各种疾病。
