Therapeutic agent preparations for delivery 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 for delivering PTH or PTH analogue to a patient in need thereof, the method comprising:
providing a swallowable enclosure having an interior, a delivery means, and a PTH or PTH analogue preparation coupled to the delivery means, the PTH or PTH analogue preparation comprising a therapeutically effective dose of PTH or PTH analogue, the delivery means having a first configuration and a second configuration, the preparation being contained within the interior in the first configuration and advanced out of the interior and into a gastro-intestinal (GI) lumen wall in the second configuration so as to deliver the PTH or PTH analogue preparation into the GI lumen wall, the enclosure protecting the PTH or PTH analogue preparation from degradation by GI fluids, the PTH or PTH analogue preparation supplied in the enclosure in a form which can be delivered from the enclosure into the GI lumen wall by the application of force on the preparation; and
triggering the delivery means within the GI lumen responsive to a condition in the lumen to deliver the PTH or PTH analogue preparation from the enclosure into the GI lumen wall, wherein the dose of PTH or PTH analogue is released into the patient's blood stream.
2. The method of claim 1 , wherein the GI lumen is the small intestine.
3. The method of claim 1 , wherein the GI lumen is the stomach.
4. The method of claim 1 , wherein the condition is a selected pH.
5. The method of claim 4 , wherein the pH is above about 7.1.
6. The method of claim 1 , wherein a weight percent of PTH or PTH analogue in the PTH or PTH analogue preparation comprises between about 1 to 2%.
7. The method of claim 1 , wherein a dose of PTH or PTH analogue in the PTH or PTH analogue preparation is in a range from 10 to 30 μg.
8. The method of claim 1 , wherein the PTH analogue is teriparatide.
9. The method of claim 8 , wherein a dose of teriparatide in the preparation is in a range from about 0.1 to 10 μg.
10. The method of claim 1 , wherein the PTH or PTH analogue preparation comprises at least one pharmaceutical excipient.
11. The method of claim 10 , wherein the at least one pharmaceutical excipient comprises at least one of a binder, a preservative or a disintegrant.
12. The method of claim 1 , further comprising retaining the PTH or PTH analogue preparation within the GI lumen wall.
13. The method of claim 12 , wherein retaining comprises anchoring a portion of the PTH or PTH analogue preparation in GI lumen wall tissue.
14. The method of claim 1 , wherein delivering the PTH or PTH analogue preparation comprises applying a force to the PTH or PTH analogue preparation.
15. The method of claim 14 , wherein the PTH or PTH analogue preparation is advanced completely into the GI lumen wall by such application of force.
16. The method of claim 14 , wherein the PTH or PTH analogue preparation is advanced through the GI lumen wall by such application of force.
17. The method of claim 14 , wherein the force is a mechanical force applied to a surface of PTH or PTH analogue preparation.
18. The method of claim 1 , wherein the PTH or PTH analogue preparation produces a long-term release of the PTH or PTH analogue.
19. The method of claim 18 , wherein the long term release of PTH or PTH produces is about 12 hours.
20. The method of claim 1 , wherein the delivery means comprises an expandable balloon.
21. The method of claim 1 , wherein the delivery means comprises a spring.
22. The method of claim 1 , wherein the PTH or PTH preparation is shaped as a tissue penetrating member.
23. A method for treating a PTH or PTH responsive condition in a patient, the method:
providing a swallowable enclosure having an interior, a delivery means, and a PTH or PTH analogue preparation coupled to the delivery means, the PTH or PTH analogue preparation comprising a therapeutically effective dose of PTH or PTH analogue, the delivery means having a first configuration and a second configuration, the preparation being contained within the interior in the first configuration and advanced out of the interior and into a gastro-intestinal (GI) lumen wall in the second configuration so as to deliver the PTH or PTH analogue preparation into the GI lumen wall, the enclosure protecting the PTH or PTH analogue preparation from degradation by GI fluids, the PTH or PTH analogue preparation supplied in the enclosure in a form which can be delivered from the enclosure into the GI lumen wall by the application of force on the preparation;
triggering the delivery means within the GI lumen responsive to a condition in the lumen to deliver the PTH or PTH analogue preparation from the enclosure into the GI lumen wall, wherein the dose of PTH or PTH analogue is released into the patient's blood stream; and
using the dose of released PTH or PTH analogue to treat the PTH or PTH responsive condition in the patient.
24. The method of claim 23 , wherein the PTH or PTH analogue responsive condition is osteoporosis.
25. The method of claim 23 , wherein the PTH or PTH analogue responsive condition is hypoparathyroidism.
