    Abstract: 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.

    Abstract: Among other things, the present disclosure relates to chirally controlled oligonucleotides of select designs, chirally controlled oligonucleotide compositions, and methods of making and using the same. In some embodiments, a provided chirally controlled oligonucleotide composition provides different cleavage patterns of a nucleic acid polymer than a reference oligonucleotide composition. In some embodiments, a provided chirally controlled oligonucleotide composition provides single site cleavage within a complementary sequence of a nucleic acid polymer. In some embodiments, a chirally controlled oligonucleotide composition has any sequence of bases, and/or pattern or base modifications, sugar modifications, backbone modifications and/or stereochemistry, or combination of these elements, described herein.
