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 infliximab to a patient, said method comprising:
providing a swallowable enclosure having an interior, a delivery means, and containing an infliximab preparation in a solid form coupled to the delivery means, the infliximab preparation comprising a therapeutically effective dose of infliximab, 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 infliximab preparation into the GI lumen wall, the enclosure protecting the infliximab preparation from degradation by GI fluids, the infliximab preparation supplied in the enclosure in a solid form which is delivered from the enclosure into the GI lumen wall by application of force on the preparation; and
triggering the delivery means within the GI lumen responsive to a condition in the lumen to advance the infliximab preparation in a solid form out of the interior of the enclosure and deliver the infliximab preparation in a solid form into the GI lumen wall by application of force on the preparation, wherein the dose of infliximab 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 the dose of infliximab in the infliximab preparation is in a range from about 1 to 10 mg.
7. The method of claim 1 , wherein the dose of infliximab in the infliximab preparation is about 5 mg.
8. The method of claim 1 , wherein the infliximab preparation comprises at least one pharmaceutical excipient.
9. The method of claim 1 , wherein the infliximab preparation comprises at least one pharmaceutical excipient.
10. The method of claim 9 , wherein the at least one pharmaceutical excipient comprises at least one of a binder, a preservative or a disintegrant.
11. The method of claim 1 , further comprising retaining the infliximab preparation within the GI lumen wall.
12. The method of claim 11 , wherein retaining comprises anchoring a portion of the infliximab preparation in GI lumen wall tissue.
13. The method of claim 1 , wherein the infliximab preparation is advanced completely into the GI lumen wall by such application of force.
14. The method of claim 1 , wherein the infliximab preparation is advanced through the GI lumen wall by such application of force.
15. The method of claim 1 , wherein the force is a mechanical force applied to a surface of the infliximab preparation.
16. The method of claim 1 , wherein the release of the infliximab dose into the patient's blood stream results in a t % of about 40 days.
17. The method of claim 1 , wherein the delivery means comprises an expandable balloon.
18. The method of claim 1 , wherein the delivery means comprises a spring.
19. The method of claim 1 , wherein the infliximab preparation is shaped as a tissue penetrating member.
