Application Number:	US15/308,027
Patent Claims:	1. A compound comprising a modified oligonucleotide and a conjugate group, wherein the modified oligonucleotide consists of 20 linked nucleosides and has the nucleobase sequence of SEQ ID NO: 570, wherein the modified oligonucleotide comprises at least 1 phosphodiester internucleoside linkage, and wherein the conjugate group is covalently linked to the modified oligonucleotide at the 5′ end of the modified oligonucleotide, and wherein the conjugate group comprises: 2. The compound of claim 1, wherein the compound consists of the modified oligonucleotide and the conjugate group, and wherein the modified oligonucleotide is single-stranded. 3. The compound of claim 1, wherein at least one internucleoside linkage of the modified oligonucleotide is a modified internucleoside linkage. 4. The compound of claim 3, wherein the at least one modified internucleoside linkage is a phosphorothioate internucleoside linkage. 5. The compound of claim 1, wherein the modified oligonucleotide comprises at least 2 phosphodiester internucleoside linkages. 6. The compound of claim 1, wherein the modified oligonucleotide comprises at least 3 phosphodiester internucleoside linkages. 7. The compound of claim 1, wherein the modified oligonucleotide comprises at least 4 phosphodiester internucleoside linkages. 8. The compound of claim 1, wherein each internucleoside linkage of the modified oligonucleotide is selected from a phosphodiester internucleoside linkage and a phosphorothioate internucleoside linkage. 9. The compound of claim 1, wherein at least one nucleoside of the modified oligonucleotide comprises a modified nucleobase, and wherein the at least one modified nucleobase is a 5-methylcytosine. 10. The compound of claim 1, wherein the modified oligonucleotide comprises at least one modified sugar. 11. The compound of claim 10, wherein the modified sugar is any of a 2′-O-methoxyethyl, 2′-O-methyl, a constrained ethyl, a LNA, or a 3′-fluoro-HNA. 12. The compound of claim 1, wherein the modified oligonucleotide comprises: a gap segment consisting of 10 linked deoxynucleosides; a 5′ wing segment consisting of 5 linked nucleosides; and a 3′ wing segment consisting of 5 linked nucleosides; wherein the gap segment is positioned between the 5′ wing segment and the 3′ wing segment and wherein each nucleoside of each wing segment comprises a modified sugar. 13. A modified oligonucleotide according to the following formula: (SEQ ID NO: 570). 14. A composition comprising a modified oligonucleotide of the following formula: (SEQ ID NO: 570) and a pharmaceutically acceptable carrier or diluent. 15. A composition comprising the compound of claim 1 and at least one of a pharmaceutically acceptable carrier or diluent. 16. A method comprising administering to an animal the compound of claim 1, wherein the animal is a human. 17. The method of claim 16, wherein administering the compound prevents, treats, or ameliorates a PKK associated disease, disorder or condition. 18. The compound of claim 8, wherein the modified oligonucleotide comprises four phosphodiester internucleoside linkages and 15 phosphorothioate internucleoside linkages. 19. The modified oligonucleotide of claim 13, which is a salt of the formula. 20. The composition of claim 14, wherein the pharmaceutically acceptable carrier or diluent is phosphate-buffered saline (PBS). 21. The composition of claim 14, wherein the composition consists essentially of the modified oligonucleotide and PBS.
