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).

Provided herein are MAPT RNAi agents and compositions comprising a MAPT RNAi agent. Also provided herein are methods of using the MAPT RNAi agents or compositions comprising a MAPT RNAi agent for reducing MAPT expression and/or treating tauopathy in a subject.

Described are RNAi agents, compositions that include RNAi agents, and methods for inhibition of a Mucin 5AC (MUC5AC) gene. The MUC5AC RNAi agents and RNAi agent conjugates disclosed herein inhibit the expression of an MUC5AC gene. Pharmaceutical compositions that include one or more MUC5AC RNAi agents, optionally with one or more additional therapeutics, are also described. Delivery of the described MUC5AC RNAi agents to pulmonary epithelial cells, in vivo, provides for inhibition of MUC5AC gene expression and a reduction in MUC5AC production, which can provide a therapeutic benefit to subjects, including human subjects, for the treatment of various diseases including mucoobstructive lung disease such as severe asthma and various cancers.

Disclosed herein are polynucleic acid molecules, pharmaceutical compositions, and methods for treating Facioscapulohumeral muscular dystrophy.

The present invention is in the field of pharmaceutical compounds and preparations and method of their use in the treatment of disease. Described are short interfering nucleic acid (siNA) molecules comprising modified nucleotides, compositions containing the same, and uses thereof for treating or preventing coronavirus infections. In particular, the present invention is in the field of siNA molecules effective against a broad spectrum of coronaviruses, and especially the β-coronaviruses, including SARS-CoV-2, the causative agent of COVID-19.

This invention relates to methods and compositions useful for treatment of subjects with dry age-related macular degeneration or geographic atrophy secondary to dry age-related macular degeneration. The methods involve administration of a pharmaceutical composition comprising an anti-05 agent ARC1905, which comprises a C5-specific aptamer conjugated to a polyethylene glycol moeity via a linker, in an amount effective for slowing or inhibiting loss of low luminance visual acuity in the subject. The aptamer consists of the sequence fCmGfCfCGfCmGmGfUfCfUfCmAmGmGfCGfCfUmGmAmGfUfCfUmGmAmGfUfUfUAfCf CfUmGfCmG-3T, wherein fC and fU=2′ fluoro nucleotides, mG and mA=2′-OMe nucleotides, all other nucleotides are 2′-OH, and 3T indicates an inverted deoxythymidine. Dosages and administration schedules are disclosed.

The invention relates to saRNA targeting an HNF4a transcript and therapeutic compositions comprising said saRNA. Methods of using the therapeutic compositions are also provided.

Described herein are aptamers capable of binding to human complement component 3 (C3) protein; compositions comprising a C3 binding aptamer with a C3-Protein; and methods of making and using the same.

Disclosed herein are polynucleic acid molecules, pharmaceutical compositions, and methods for treating facioscapulohumeral muscular dystrophy (FSHD).

The invention provides compositions and methods for reducing expression of a target gene in a cell, involving contacting a cell with an isolated double stranded nucleic acid (dsNA) in an amount effective to reduce expression of a target gene in a cell. The dsNAs of the invention possess a single stranded extension (in most embodiments, the single stranded extension comprises at least one modified nucleotide and/or phosphate back bone modification). Such single stranded extended Dicer-substrate siRNAs (DsiRNAs) were demonstrated to be effective RNA inhibitory agents compared to corresponding double stranded DsiRNAs.
