Therapeutic agent preparations for delivery into a lumen of the intestinal tract using a swallowable drug delivery device
First Claim
1. A method for delivering interferon to a patient, the method comprising:
- providing a solid interferon dosage as a tissue penetrating member shaped and configured to penetrate and be inserted into the intestinal wall, the tissue penetrating member enclosed in a swallowable capsule comprising materials which protect the solid interferon dosage from degradation within the intestinal tract;
ingesting the solid interferon dosage, wherein the dosage is not substantially degraded in the intestinal tract prior to insertion into an intestinal wall;
penetrating the solid interferon dosage into the intestinal wall after oral ingestion by the application of mechanical force on the tissue penetrating member such that the tissue penetrating member is retained within the intestinal wall; and
,degrading the solid interferon dosage within the intestinal wall to release the interferon into the intestinal wall and then into the blood stream.

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 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.
