    摘要: The present disclosure provides recombinantly manufactured ultra-long acting insulin-Fc fusion proteins for use in treating canine diabetes. The insulin-Fc fusion proteins comprise an insulin polypeptide linked via a peptide linker to an Fc-fragment of canine origin. Based on the results obtained, creating a treatment that is amenable to low cost manufacturing, exhibits sufficient in vivo bioactivity, displays extended duration of bioactivity, does not induce anti-drug antibodies, and substantially retains is potency over multiple administrations, requires a non-obvious combination of insulin polypeptide, peptide linkers, and species-specific Fc fragment, in addition to selective mutations on one or more of these components. Exemplary ultra-long acting insulin-Fc fusion proteins, polynucleotides encoding these insulin-Fc fusion proteins, and pharmaceutical formulations of exemplary insulin-Fc fusion proteins are provided, in addition to methods of use and preparation.

    摘要: A single-chain insulin analogue comprises the insulin B-chain polypeptide sequence, the insulin A-chain polypeptide sequence, and a connecting polypeptide sequence of 5-11 amino acids linking the C-terminal amino acid of the B-chain polypeptide to the N-terminal amino acid of the A-chain polypeptide. The analogue comprises an acetylated Lys at a location selected from the group consisting of any of the amino acids in the connecting polypeptide, B0-B3, B28-B29 or A14, relative to wild type insulin, or comprises an acetylated amino acid at the N-terminal amino acid of the single-chain insulin analogue. The single-chain insulin analogue may be acylated with a C6-C21 fatty acid, which may be attached to the e-amino group of a unique Lysine residue or the a-amino group of the N-terminal amino acid of the single-chain insulin analogue. The insulin analogue may be used to lower the blood sugar of a patient in need thereof.
