  • Publication number: 20230241054
    Abstract: The invention provides compositions and methods for the treatment or prevention of pain. The invention provides constructs whereby hydrolysis of the construct by a specified gastrointestinal enzyme directly, or indirectly, releases an opioid when taken orally as prescribed. The gastrointestinal enzyme mediated release of opioid from constructs of the invention is designed to be attenuated in vivo via a saturation or inhibition mechanism when overdoses are ingested. The invention further provides constructs that are highly resistant to oral overdose, chemical tampering, and abuse via non-oral routes of administration.

  • Patent number: 11400062
    Abstract: Pharmaceutical compositions and their methods of use are provided, where the pharmaceutical compositions comprise an amphetamine prodrug that provides enzymatically-controlled release of amphetamine or an amphetamine analog. The composition can further comprise an enzyme inhibitor that interacts with the enzyme(s) that mediates the enzymatically-controlled release of amphetamine or the amphetamine analog from the amphetamine prodrug so as to attenuate enzymatic cleavage of the amphetamine prodrug.

  • Publication number: 20220175699
    Abstract: The embodiments provide Compound AM-9, Amphetamine-arginine-glycine-acetate, or acceptable salts, solvates, and hydrates thereof and Compound AM-10, Amphetamine-arginine-alanine-acetate. The present disclosure also provides compositions, and their methods of use, where the compositions comprise a prodrug, Compound AM-9 or Compound AM-10, that provides controlled release of amphetamine Such compositions can optionally provide a trypsin inhibitor that interacts with the enzyme that mediates the controlled release of amphetamine from the prodrug so as to attenuate enzymatic cleavage of the prodrug.

  • Patent number: 11318132
    Abstract: The present invention provides a composition comprising an opioid agonist, and a polymer-antagonist conjugate. The polymer-antagonist conjugate preferably does not hydrolyze upon administration to a patient, and does not bind to the opioid receptors. The covalent bond between the polymer and the antagonist in the conjugate is broken over a defined period of time to release the antagonist into the formulation. The released antagonist attenuates the liking of the agonist, thereby eliminating the incentive to the diversion of the medicines.

  • Publication number: 20220054479
    Abstract: The invention provides pharmaceutical compositions comprising macromolecular gastrointestinal enzyme-labile opioid prodrugs, co-formulated with small-molecule and/or macromolecular gastrointestinal enzyme inhibitors. The macromolecular constructs are minimally absorbed from the GI tract, and can produce non-linear pharmacokinetic profiles of the delivered opioid agonist following oral ingestion. An optional macromolecular opioid antagonist may also be present in compositions of the invention to discourage tampering by potential abusers.

  • Patent number: 10028945
    Abstract: A method of providing a patient with controlled release of ketone-containing opioid using a prodrug capable, upon enzymatic activation and intramolecular cyclization, of releasing the ketone-containing opioid is disclosed. The disclosure also provides such prodrug compounds and pharmaceutical compositions comprising such compounds. Such pharmaceutical compositions can optionally include an enzyme inhibitor that interacts with the enzyme(s) to mediate the enzymatically-controlled release of the ketone-containing opioid from the prodrug so as to modify enzymatic cleavage of the prodrug. Also included are methods to use such compounds and pharmaceutical compositions.
