Clotting factor preparations for delivery into tissue of the intestinal tract using a swallowable drug delivery device
Embodiments provide devices, preparations and methods for delivering therapeutic agents (TAs) such as clotting factors (CFs, e.g., Factor 8) within the GI tract. Many embodiments provide a swallowable device e.g., a capsule for delivering TAs into the intestinal wall (IW). Embodiments also provide TA preparations configured to be contained within the capsule, advanced from the capsule into the IW and/or surrounding tissue (ST) and degrade to release the TA into the bloodstream to produce a therapeutic effect (e.g., improved clotting). The preparation can be operably coupled to delivery means having a first configuration where the preparation is contained in the capsule and a second configuration where the preparation is advanced out of the capsule into the IW or ST (e.g., the peritoneal cavity). Embodiments are particularly useful for delivery of CFs for treatment of clotting disorders (e.g., hemophilia) where such CFs are poorly absorbed and/or degraded within the GI tract.
1. A method for treating a clotting disorder in a patient, wherein the clotting factor disorder is one or more selected from hemophilia A, hemophilia B, Factor VII deficiency, Glanzmann's Thrombasthenia, Factor X deficiency, and Von Willebrand's disease, the method comprising:
administering to a patient in need thereof by swallowing a swallowable device, the swallowable device comprising a swallowable capsule, a tissue penetrating member disposed in the capsule, a therapeutic agent disposed in, or formed into the shape of, the tissue penetrating member, and an actuation mechanism operably coupled to the tissue penetrating member, wherein the therapeutic agent comprises a clotting factor in a biologically active form that promotes or accelerates clotting in the patient;
wherein the tissue penetrating member is advanced out of the capsule by the actuation mechanism such that the tissue penetrating member is advanced through an intestinal wall of the patient and inserted into a peritoneal cavity of the patient after swallowing of the swallowable device;
wherein after insertion into the peritoneal cavity, the tissue penetrating member releases the therapeutic agent in its biologically active form to treat the clotting disorder and is degraded in serosal fluids of the peritoneal cavity.
2. The method of claim 1 , wherein the tissue penetrating member has a column strength in a range of about 1 to 20 lbs.
3. The method of claim 1 , wherein the tissue penetrating member is structured as a shaft having a pointed end.
4. The method of claim 3 , wherein the tissue penetrating member includes a degradation feature configured to enhance a rate of degradation of the tissue penetrating member in serosal fluids of the peritoneal cavity.
5. The method of claim 4 , wherein the degradation feature comprises an aperture in the tissue penetrating member.
6. The method of claim 4 , wherein the degradation feature comprises a channel in a surface of the tissue penetrating member.
7. The method of claim 4 , wherein the degradation feature is positioned and configured to facilitate fracture or breakage of the tissue penetrating member by forces applied by the patient's body to the peritoneal cavity.
8. The method of claim 1 , wherein the tissue penetrating member is detachably coupled to the actuation mechanism, and wherein the actuation mechanism applies a mechanical force on an end of the tissue penetrating member to advance the tissue penetrating member through the intestinal wall and into the peritoneal cavity of the patient.
9. The method of claim 1 , wherein the clotting factor disorder comprises hemophilia A and the clotting factor comprises Factor VIII (F8) or a Factor VIII analogue (F8A).
10. The method of claim 9 , wherein a dose of F8 or F8A in the preparation is in a range of about 400 IU to 10,000 IU.
11. The method of claim 9 , wherein a dose of F8 or F8A in the preparation is in a range of about 0.01 mg to 3 mg.
12. The method of claim 1 , wherein the clotting factor disorder comprises one or both of Factor VII deficiency and Glanzmann's Thrombasthenia and the clotting factor comprises Factor VII (F7) or a Factor VII analogue (F7A).
13. The method of claim 12 , wherein a dose of F7 or F7A in the preparation is in a range of about 0.03 mg to 3 mg.
14. The method of claim 12 , wherein a dose of F7 or F7A in the preparation is in a range of about 1.5 mg to 10 mg.
15. The method of claim 12 , wherein a dose of F7 or F7A in the preparation is in a range of about 400 IU to 10,000 IU.
16. The method of claim 1 , wherein the clotting factor disorder comprises hemophilia B and the clotting factor comprises Factor IX (F9) or a Factor IX analogue (F9A).
17. The method of claim 16 , wherein a dose of F9 or F9A in the preparation is in a range of about 0.03 mg to 3 mg.
18. The method of claim 16 , wherein a dose of F9 or F9A in the preparation is in a range of about 400 IU to 10,000 IU.
19. The method of claim 16 , wherein a dose of F9 or F9A in the preparation is in a range of about 7 mg to 10.6 mg.
20. The method of claim 1 , wherein the clotting factor disorder comprises Factor X deficiency and the clotting factor comprises Factor X (F10) or a Factor X analogue (F10A).
21. The method of claim 20 , wherein a dose of F10 or F10A in the preparation is in a range of about 0.03 mg to 3 mg.
22. The method of claim 20 , wherein a dose of F10 or F10A in the preparation is in a range of about 20 mg to 33 mg.
23. The method of claim 20 , wherein a dose of F10 or F10A in the preparation is in a range of about 400 IU to 10,000 IU.
