Abstract

A solid dosage form for injection and a method of making said dosage form wherein the dosage form has a moisture content of 5% (w/w) or less. The solid dosage form comprises a dried matrix including a first excipient and 0.01 to 50% (w/w) or more than 50% and up to 80% (w/w) of a therapeutic peptide; and one or more additional excipients and at least 5% (w/w) of CMC, based on the total weight of the solid dosage form, wherein the dosage form has a width of 0.5 mm to 2 mm.

Claims (34)

1. A solid dosage form comprising:

a freeze dried matrix including a first excipient and 0.01 to 50% (w/w) of a therapeutic peptide; and

a bulk component comprising the freeze dried matrix, one or more additional excipients and at least 5% (w/w) of carboxymethyl cellulose (CMC), based on the total weight of the solid dosage form,

wherein the dosage form has a maximum width of 0.5 mm to 2 mm,

wherein the dosage form has a pointed end configured to facilitate skin penetration,

wherein the pointed end is in the form of a cone or in the form of a beveled tip that is formed from two or more intersecting surfaces meeting at a common point,

wherein the first excipient is a polyol, sugar, surfactant, amino acid, EDTA and/or stabilising agent,

wherein the one or more additional excipients is at least one of a polyol, sugar, surfactant, amino acid, EDTA and/or stabilising agent, and

wherein the solid dosage form is injectable and has a moisture content of 5% (w/w) or less.

2. A solid dosage form according to claim 1 , wherein when the pointed end is in the form of the cone, a diameter of the dosage form at a base of the cone is the maximum width and a radius of the pointed end at an end opposite the base is a top radius of the pointed end, and wherein the top radius is less than half the maximum width.

3. A solid dosage form according to claim 1 , wherein when the pointed end is in the form of the cone, a diameter of the dosage form at a base of the cone is the maximum width and a radius of the pointed end at an end opposite the base is a top radius of the pointed end, and wherein the top radius is less than one fourth of the maximum width.

4. A solid dosage form according to claim 1 , wherein when the pointed end is in the form of the beveled tip, the intersecting surfaces form an angle between 10 and 110 degrees at the common point.

5. A solid dosage form according to claim 1 , wherein when the pointed end is in the form of the beveled tip, the intersecting surfaces form an angle between 10 and 90 degrees at the common point.

6. A solid dosage form according to claim 1 , wherein when the pointed end is in the form of the beveled tip, the intersecting surfaces form an angle between 20 and 65 degrees at the common point.

7. A solid dosage form according to claim 1 , wherein when the pointed end is in the form of the beveled tip, the intersecting surfaces form an angle between 40 and 60 degrees at the common point.

8. A solid dosage form according to claim 1 , wherein the moisture content is between 2% and 3% (w/w).

9. A solid dosage form according to claim 1 , wherein the first excipient and/or at least one of said one or more additional excipients is a polyol.

10. A solid dosage form according to claim 1 , wherein the first excipient and/or at least one of said one or more additional excipients is mannitol.

11. A solid dosage form according to claim 1 , wherein the therapeutic peptide is octreotide, PTH 1-34, exenatide or liraglutide.

12. A solid dosage form according to claim 1 , wherein the maximum width of the dosage form is 0.5 to 1 mm.

13. A solid dosage form according to claim 1 , wherein the maximum width of the dosage form is 0.85 mm.

14. A solid dosage form according to claim 1 , wherein the length of the dosage form is from 2 to 6 mm.

15. A solid dosage form according to claim 1 , wherein the length of the dosage form is 4 mm.

16. A solid dosage form according to claim 1 , wherein the compressive strength of the dosage form is at least 80 MPa.

17. A solid dosage form according to claim 1 , wherein the compressive strength of the dosage form is at least 100 MPa.

18. A solid dosage form according to claim 1 , wherein the total weight of the solid dosage form is 1 to 5 mg.

19. A drug delivery system comprising:

a drug delivery device; and

the solid dosage form according to claim 1 .

20. A method of producing the solid dosage form of claim 1 , the method comprising the steps of:

producing a blend of the therapeutic peptide, the first excipient, the CMC, and one or more additional excipients;

adding water to the blend to make a paste; and

processing the paste to form the solid dosage form.

21. A solid dosage form according to claim 1 , wherein the solid dosage form is in the form of a packaged drug for use with a drug delivery device.
