Abstract

Fatty acid compositions for administration of of pharmaceutical agents, such as proteins and peptides, protein and peptide conjugates, and/or cation-polypeptide conjugate complexes. In particular, the invention provides a solid pharmaceutical composition formulated for oral administration by ingestion, having from about 0.1 to about 75% w/w fatty acid component, where the fatty acid component comprises saturated or unsaturated C4, C5, C6, C7, C8, C9, C10, C11, or C12 fatty acids and/or salts of such fatty acids; and a therapeutic agent. Further, the invention provides a liquid pharmaceutical composition formulated for oral administration by ingestion, comprising: from about 0.1 to about 10% w/v fatty acid component, where the fatty acid component comprises saturated or unsaturated C4, C5, C6, C7, C8, C9, C10, C11, or C12 fatty acids and/or salts of such fatty acids; and a therapeutic agent.

Claims

1. A pharmaceutical composition formulated for oral administration by ingestion, comprising:

(a) from about 5 to about 65% w/w of a salt of a fatty acid component, wherein the salt of the fatty acid component is selected from salt of capric acid, salt of lauric acid and combinations thereof; and

(b) an insulin compound conjugate comprising an insulin protein coupled to a modifying moiety having a structure;

2. The pharmaceutical composition of claim 1 comprising from about 40 to about 60% w/w of the salt of a fatty acid component.

3. The pharmaceutical composition of claim 1 comprising at least one member selected from the group consisting of binders, disintegrants, fillers, diluents, lubricants, glidants, flow enhancers, compression aids, colors, sweeteners, preservatives, suspensing agents, dispersing agents, film formers, coatings, flavors, printing inks, celluloses, sugars, mannitols, lactoses, dissolution enhancers, and crosscarmaloses.

4. The pharmaceutical composition of claim 1 prepared in a form selected from the group consisting of semisolids, suspensions, microemulsions, and emulsions.

5. The pharmaceutical composition of claim 1 comprising a buffer salt selected from the group consisting of phosphate buffer, sodium phosphate, tris buffer, citric acid buffer, and ethanolamine buffer.

6. The pharmaceutical composition of claim 1 comprising a buffer salt selected to achieve a buffering capacity at the site of absorption to maintain a local pH of from about 5 to about 8.

7. The pharmaceutical composition of claim 1 where the insulin compound conjugate consists of human insulin coupled to the modifying moiety on at least one amino acid residue selected from the group A1, B1, B29 and a combination thereof.

8. The pharmaceutical composition of claim 1 where the insulin compound conjugate consists of human insulin coupled at B29.

9. The pharmaceutical composition of claim 1, wherein the salt of fatty acid is sodium caprate.

10. The pharmaceutical composition of claim 1, wherein the composition is a solid or liquid.

11. The pharmaceutical composition of claim 1, wherein the insulin compound conjugate is complexed with zinc and the water solubility is decreased by the addition of zinc.
