Abstract

Embodiments of the invention provide swallowable devices, preparations and methods for delivering drugs and other therapeutic agents within the GI tract. Many embodiments provide a swallowable device for delivering the agents. Particular embodiments provide a swallowable device such as a capsule for delivering drugs into the intestinal wall or other GI lumen. Embodiments also provide various drug preparations that are configured to be contained within the capsule, advanced from the capsule into the intestinal wall and degrade within the wall to release the drug to produce a therapeutic effect. The preparation can be coupled to an actuator 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 intestinal wall. Embodiments of the invention are particularly useful for the delivery of drugs which are poorly absorbed, tolerated and/or degraded within the GI tract.

Claims

1. A therapeutic agent preparation for delivery into a lumen of the intestinal tract, the lumen having a lumen wall, the preparation comprising a therapeutically effective dose of at least one therapeutic agent, wherein the preparation is a solid shaped as a tissue penetrating member having a dart-like structure, the tissue penetrating member configured to be contained in an oval shaped swallowable capsule and to be delivered from the capsule to penetrate and be advanced into the lumen wall by the application of force on the tissue penetrating member, wherein the solid degrades within the lumen wall to release the dose of therapeutic agent.

2. The preparation of claim 1, wherein the lumen is the small intestine and the preparation is configured to degrade within the wall of the small intestine.

3. The preparation of claim 1, wherein the preparation comprises at least one pharmaceutical excipient.

4. The preparation of claim 1, wherein the preparation is configured to have a selectable surface area to volume ratio to achieve a selectable rate of release of the therapeutic agent in the lumen wall.

5. The preparation of claim 1, wherein an amount of the therapeutic agent within the preparation to produce a desired therapeutic effect is less than an amount to produce a corresponding effect if the agent was orally delivered without enclosure in the swallowable capsule.

6. The preparation of claim 1, wherein the preparation is configured to be coupled to an actuator having a first configuration and a second configuration, the preparation being contained within the capsule in the first configuration and advanced out of the capsule and into the lumen wall in the second configuration.

7. The preparation of claim 1, wherein the preparation is configured to be delivered within a lumen of a tissue penetrating member.

8. The preparation of claim 1, wherein the therapeutic agent comprises a therapeutically effective dose of an incretin for the treatment of diabetes or a glucose regulation disorder.

9. The preparation of claim 8, wherein the incretin comprises a glucagon like peptide-1 (GLP-1), a GLP-1 analogue, exenatide, liraglutide, albiglutide, taspoglutide or a gastric inhibitory polypeptide (GIP).

10. The preparation of claim 8, wherein the incretin comprises exenatide and the dose is in a range from about 1 to 10 μ

g.

11. The preparation of claim 8, wherein the incretin comprises liraglutide and the dose is in a range from about 1 to 2 mg.

12. The preparation of claim 1, wherein the therapeutic agent comprises a combination of therapeutic agents for the treatment of diabetes or a glucose regulation disorder.

13. The preparation of claim 12, wherein the combination comprises a therapeutically effective dose of an incretin and a therapeutically effective dose of a biguanide.

14. The preparation of claim 13, wherein the incretin comprises exenatide and the biguanide comprises metformin.

15. The preparation of claim 13, wherein the dosages of the incretin and the biguanide are matched to produce an improved level of blood glucose control for an extended period.
