Definitions

  • the invention relates to therapeutic agents for internal administration to an animal body such as a human and to methods of their manufacture and administration.
  • Prior Art Internally administered therapeutic agents usually ' encompass drugs and other non-living materials which are ingested by a user, or implanted or inserted in the user for therapeutic purposes. They are delivered to the body of the user in a variety of ways, such as in the form of capsules for oral administration or or by insertion as suppositories, or in the form of liquids for oral administration or injection, among other techniques. Also, living organisms have been administered by injection e.g., small pox, vaccination, or- by the oral route in the form of liquid droplets e.g., Sabin polio immunization. These agents are prepared by a variety of manufacturing processes, and are stored until their administration to the end user.
  • Objects of the Invention Accordingly, it is an object of the invention to provide an improved mechanism for administering selected therapeutic agents derived from genetically altered organism to an animal body. Further, it is an object of my invention to provide an improved method of generating therapeutic agents derived from genetically altered organisms for administration to an animal body.
  • genetically programmed organisms which produce the desired therapeutic agents to be administered to an animal m body such as a human are prepared in situ and enclosed within a protective membrane providing mechanical confinement to the organisms while they are being administered to the animal body.
  • the membrane may include an inner layer containing material providing sustenance to the enclosed bacteria for at least the time they are outside the human body, or a nutrient material may be included in the organism section of the chamber itself.
  • a microporous membrane that contains the organisms but allows passage of nutrients from a nutrient source or culture medium may be employed.
  • the membrane and its contents may be orally ingested by the human, or may be inserted as a suppository or otherwise implanted within the body.
  • the capsule may either remain intact, exchanging its therapeutic product for nutrients until removed or excreted, or may dissolve, allowing the therapeutic organisms to colonize the target areas releasing their therapeutic products there.
  • a genetically altered strain is preselected that itself produces the therapeutic agent which is to be utilized by the body.
  • altered bacteria of the type E. Coli produce insulin which is used to treat diseases such as diabetes.
  • the membrane dissolves within the body to a sufficient extent to release the enclosed bacteria.
  • the bacteria then operate, within the body environment, to produce the selected therapeutic agent [e_.g, insulin].
  • the number of bacteria are, of course, proportioned to the desired dosage of agent to be administered to the body, taking into consideration the type of bacteria, the specific portion of the body in which they were lodged, and their expected lifetime and productivity time within that body portion.
  • the therapeutic agent is generated by the bacteria within the membrane and is transferred across the membrane walls by A-
  • the membrane walls 5 may be such as to be dissolvable when ingested or 6 inserted into the body, or may be such that the walls 7 are relatively resistant to degradation within the 8 body but allow passage of therapeutic products 9 generated by the bacteria into the body.
  • dissolvable capsules may be modified 1 to dissolve under optimal conditions for specific 2 locality colonization and as such may be acid 3 resistant and more soluable in an alkaline environment 4 for intestinal colonization, or by other physical or 5 chemical modifications designed to enhance successful

  • Wall 10 may comprise a 5 material such as gelatin which is essentially 6 impermeable both to the organism and to the 7 therapeutic agents formed thereby, but which is broken 8 down by the body on ingestion or insertion of the 9 device into it or, alternatively, may comprise a 0 material such as a icroporous membrane which has a 1 pore size sufficient to allow passage of the 2 therapeutic agents formed by the organisms through the 3 membrane wall and into the body on ingestion or 4 insertion therein, while blocking escape of the 5 organism therethrough, and which is relatively inert 6 to degradation by the body when ingested or inserted.

Abstract

Un dispositif consiste en des organismes programmés génétiquement enfermés dans une variété de structures à membranes pour former une capsule thérapeutique. Cette capsule, lorsqu'elle est administrée en une personne, produit des agents thérapeutiques et peut, soit rester intacte jusqu'à être expulsée ou retirée, soit dissoudre sa paroi pour permettre aux organismes enfermés de coloniser les régions désirées pour ensuite produire les agents thérapeutiques.
