Method of delivering insulin into a lumen of the intestinal tract using a swallowable drug delivery device
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 to release the drug into the bloodstream to produce a therapeutic effect. 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 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.
1. A method of delivering insulin to a patient, the method comprising:
providing an ingestible drug delivery device comprising a capsule, an actuator having a first configuration and a second configuration, and a solid insulin preparation that (i) comprises a therapeutically effective dose of insulin, (ii) is operably coupled to the actuator, and (iii) is contained within the capsule in the first configuration of the actuator and is advanced into a wall of the gastrointestinal tract in the second configuration of the actuator; and
providing the ingestible drug delivery device to be swallowed by a patient.
2. The method of claim 1 , wherein the solid insulin preparation that is advanced into the wall of the gastrointestinal tract is retained in the wall to release insulin into the blood stream.
3. The method of claim 1 , wherein the insulin provided in the ingestible drug delivery device and advanced into the wall of the gastrointestinal tract reaches a C max in a shorter time period than a time period to achieve a C max for an extravascularly injected dose of insulin.
4. The method of claim 1 , wherein a t max for the insulin released from the solid insulin preparation that is advanced into the wall of the gastrointestinal tract is less than about 80% of a t max for an extravascularly injected dose of insulin.
5. The method of claim 1 , wherein the solid insulin preparation produces a long-term release of insulin to produce a selectable t½.
6. The method of claim 1 , wherein the solid insulin preparation comprises a biodegradable material which degrades within the intestinal wall to release insulin into the blood stream.
7. The method of claim 1 , wherein the solid insulin preparation comprises at least one pharmaceutical excipient.
8. The method of claim 1 , wherein a weight percent of insulin in the solid dosage insulin comprises between about 2 to 15%.
9. The method of claim 1 , wherein the solid insulin preparation further comprises a therapeutically effective dose of an incretin for the treatment of diabetes or a glucose regulation disorder.
10. A method of delivering insulin to a patient, the method comprising:
providing an ingestible drug delivery device comprising a capsule, an actuator having a first configuration and a second configuration, and a solid insulin preparation that (i) comprises a therapeutically effective dose of insulin, (ii) is operably coupled to the actuator, and (iii) is contained within the capsule in the first configuration of the actuator and is advanced into a wall of the gastrointestinal tract in the second configuration of the actuator; and
providing instructions to the patient to swallow the ingestible drug delivery device.
11. The method of claim 10 , wherein the solid insulin preparation that is advanced into the wall of the gastrointestinal tract is retained in the wall to release insulin into the blood stream.
12. The method of claim 10 , wherein the insulin provided in the ingestible drug delivery device and advanced into the wall of the gastrointestinal tract reaches a C max in a shorter time period than a time period to achieve a C max for an extravascularly injected dose of insulin.
13. The method of claim 10 , wherein a t max for the insulin released from the solid insulin preparation that is advanced into the wall of the gastrointestinal tract is less than about 80% of a t max for an extravascularly injected dose of insulin.
14. The method of claim 10 , wherein the solid insulin preparation produces a long-term release of insulin to produce a selectable t½.
15. The method of claim 10 , wherein the solid insulin preparation comprises a biodegradable material which degrades within the intestinal wall to release insulin into the blood stream.
16. The method of claim 10 , wherein the solid insulin preparation comprises at least one pharmaceutical excipient.
17. The method of claim 10 , wherein a weight percent of insulin in the solid dosage insulin comprises between about 2 to 15%.
18. The method of claim 10 , wherein the solid insulin preparation further comprises a therapeutically effective dose of an incretin for the treatment of diabetes or a glucose regulation disorder.
19. A method of delivering insulin to a patient, the method comprising:
configuring an ingestible drug delivery device to comprise a capsule, an actuator having a first configuration and a second configuration, and a solid insulin preparation operably coupled to the actuator, the solid insulin preparation comprising a therapeutically effective dose of insulin, the solid insulin preparation being contained within the capsule in the first configuration of the actuator and advanced into the wall of the gastrointestinal tract in the second configuration of the actuator; and
providing the ingestible device to be swallowed by a patient.
20. The method of claim 19 , wherein the solid insulin preparation that is advanced into the wall of the gastrointestinal tract is retained in the wall to release insulin into the blood stream.
21. The method of claim 19 , wherein the insulin provided in the ingestible drug delivery device and advanced into the wall of the gastrointestinal tract reaches a C max in a shorter time period than a time period to achieve a C max for an extravascularly injected dose of insulin.
22. The method of claim 19 , wherein a t max for the insulin released from the solid insulin preparation that is advanced into the wall of the gastrointestinal tract is less than about 80% of a t max for an extravascularly injected dose of insulin.
23. The method of claim 19 , wherein the solid insulin preparation produces a long-term release of insulin to produce a selectable t½.
24. The method of claim 19 , wherein the solid insulin preparation comprises a biodegradable material which degrades within the intestinal wall to release insulin into the blood stream.
25. The method of claim 19 , wherein the solid insulin preparation comprises at least one pharmaceutical excipient.
26. The method of claim 19 , wherein a weight percent of insulin in the solid dosage insulin comprises between about 2 to 15%.
27. The method of claim 19 , wherein the solid insulin preparation further comprises a therapeutically effective dose of an incretin for the treatment of diabetes or a glucose regulation disorder.
