    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: The present invention relates to chirally controlled oligonucleotides, chirally controlled oligonucleotide compositions, and the method of making and using the same. The invention specifically encompasses the identification of the source of certain problems with prior methodologies for preparing chiral oligonucleotides, including problems that prohibit preparation of fully chirally controlled compositions, particularly compositions comprising a plurality of oligonucleotide types. In some embodiments, the present invention provides chirally controlled oligonucleotide compositions. In some embodiments, the present invention provides methods of making chirally controlled oligonucleotides and chirally controlled oligonucleotide compositions.
