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.

The present disclosure relates to RNAi agents, e.g., double stranded RNAi agents, able to inhibit xanthine dehydrogenase (XDH) gene expression. Also disclosed are pharmaceutical compositions that include XDH RNAi agents and methods of use thereof. The XDH RNAi agents disclosed herein may be conjugated to targeting ligands to facilitate the delivery to cells, including to hepatocytes. Delivery of the XDH RNAi agents in vivo provides for inhibition of XDH gene expression. The RNAi agents can be used in methods of treatment of diseases, disorders, or symptoms mediated in part by XDH gene expression, such as gout and hyperuricemia.

The present invention relates to antisense LNA oligonucleotides (oligomers) complementary to ATXN3 pre-mRNA sequences, which are capable of inhibiting the expression of ATXN3 protein. Inhibition of ATXN3 expression is beneficial for the treatment of spinocerebellar ataxia.

Disclosed are nucleic acid nanoparticles, a pharmaceutical composition comprising the same, a drug comprising doxorubicin and a preparation method thereof. The nucleic acid nanoparticles have a nucleic acid structural domain, the nucleic acid structural domain includes a sequence a, a sequence b and a sequence c; the sequence a includes a sequence a1 or a sequence obtained by insertion, deletion or substitution of at least one base in the sequence a1, the sequence b includes a sequence b1 or a sequence obtained by insertion, deletion or substitution of at least one base in the sequence b1 and the sequence c includes a sequence d or a sequence obtained by insertion, deletion or substitution of at least one base in the sequence.

Provided herein, inter alia, are double stranded oligonucleotide molecules and methods of making the molecules. The double stranded oligonucleotide molecules include a first oligonucleotide strand comprising a first nucleic acid sequence bound to a second nucleic acid sequence through a first spacer, wherein said second nucleic acid sequence is bound to a third nucleic acid sequence through a second spacer and a second oligonucleotide strand comprising a fourth nucleic acid sequence bound to a fifth nucleic acid sequence through a third spacer, wherein said fifth nucleic acid sequence is bound to a sixth nucleic acid sequence through a fourth spacer, wherein the second nucleic acid sequence and the fifth nucleic acid sequence are hybridized to form a double stranded nucleic acid core of said double stranded oligonucleotide.

The invention relates to double-stranded ribonucleic acid (dsRNA) compositions targeting the ALAS1 gene, and methods of using such dsRNA compositions to alter (e.g., inhibit) expression of ALAS1.

Provided herein are methods, compounds, and compositions for reducing expression of an ANGPTL3 mRNA and protein in an animal. Also provided herein are methods, compounds, and compositions for reducing lipids and/or glucose in an animal. Such methods, compounds, and compositions are useful to treat, prevent, delay, or ameliorate any one or more of cardiovascular disease and/or metabolic disease, or a symptom thereof, in an individual in need thereof.

The present disclosure pertains to the recognition that immune responses mediated by CpG oligonucleotides can be affected by the stereochemistry of modified internucleotidic linkages such as phosphorothioates. In some embodiments, the present disclosure relates to chirally controlled CpG oligonucleotide compositions comprising CpG oligonucleotides comprising multiple modified internucleotidic linkages such as phosphorothioate linkages, wherein the oligonucleotides comprise one or more CpG region motifs having defined stereochemistry patterns of chiral internucleotidic linkages. In some embodiments, CpG oligonucleotides comprising one or more CpG region motifs are capable of agonizing an immune response. In some embodiments, CpG oligonucleotides comprising one or more CpG region motifs are antagonistic. Methods for making and using chirally controlled CpG oligonucleotide compositions are also described. In some embodiments, no immune modulation is desired, and the present disclosure provides methods of identifying chirally controlled oligonucleotide compositions which have decreased immune modulation.

Described are improved linking agents that are useful for facilitating the attachment of targeting groups, pharmacokinetic (PK) enhancers or modifiers, or other delivery agents to oligonucleotides. The described linking agents may exhibit improved reaction yields, stability, and biological activity, particularly when used in connection with oligonucleotide-based compounds, such as RNA interference (RNAi) agents.

Disclosed herein are CpG conjugated nanoparticles for immunotherapy and photothermal therapy. The composition comprises class B CpG conjugated nanoparticles and/or a class C CpG conjugated nanoparticles where the class B CpG conjugated nanoparticles comprises a nanoparticle core and a class B CpG conjugated thereto and the class C CpG conjugated nanoparticles comprises a nanoparticle core and a class C CpG conjugated thereto.
