  • Patent number: 11957736
    Abstract: The present invention concerns the use of aprotic polar solvents, water, and an ionization stabilizing agent to prepare device compatible stable therapeutic formulations by dissolving a therapeutic agent (active ingredient) in an aprotic polar solvent system that can then be used with various devices (e.g., pumps, infusion sets) for administration of the formulation. In certain embodiments, the invention is directed to formulations comprising one or more therapeutic agents, as well as methods of making such formulations, comprising at least one therapeutic agent dissolved in an aprotic polar solvent system, such as a DMSO/water admixture, comprising at least one ionization stabilizing excipient in a concentration sufficient to impart physical and chemical stability to the therapeutic agent.

  • Patent number: 11833157
    Abstract: Embodiments of the invention are directed to formulations that provide a solution to the problem of small molecule (e.g., diazepam) precipitation at the injection site when administered as a highly-concentrated formulation. In certain aspects the formulations include at least one surfactant in a non-aqueous formulation, which prevents small molecule precipitation and improves the bioavailability of the drug by enhancing absorption into the systemic circulation.

  • Publication number: 20230085357
    Abstract: The present invention provides compositions comprising one or more active pharmaceutical ingredients, wherein the compositions are in the form of high solids concentration pastes capable of being injected in relatively low volumes into an animal using standard commercially available syringes. The invention also provides methods of making such compositions, particularly those compositions comprising high molecular weight active ingredients (e.g., antibodies, enzymes and other proteins and peptides) at relatively high therapeutic concentrations in the high solids concentration pastes. The invention further provides methods of using such formulations in treating, preventing and/or ameliorating certain diseases and physical disorders in animals, including humans, in need thereof. The invention also provides kits comprising the formulations of the invention and a suitable syringe, which in some aspects may be pre-loaded or pre-filled with a composition of the invention.

  • Patent number: 11129940
    Abstract: This disclosure includes syringes, kits containing the same, and related methods. Some syringes are pre-loaded with paste and have a syringe body defining a reservoir having an internal first transverse dimension, a paste disposed within the reservoir, the paste having a solids concentration of greater than 50 mg/mL, a needle defining a lumen having an internal second transverse dimension that is smaller than the first transverse dimension, the needle configured to be in fluid communication with the reservoir to allow intracutaneous delivery of the paste, and a plunger and/or piston disposed within the reservoir and configured to be moved to dispense paste from the reservoir through the lumen. Some syringes include a fitting (e.g. Luer fitting) disposed on the syringe body and in fluid communication with the reservoir and a sealing cap disposed on the Luer fitting to seal the reservoir.
