  • 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.

  • Publication number: 20200147306
    Abstract: A method of treating congenital hyperinsulinism in a subject is disclosed. The method can include parenterally administering to the subject a first composition comprising a glucagon, a glucagon analogue, or a salt form of either thereof, and optionally administering to the subject a second composition comprising glucose, a glucose analogue, or a salt form of either thereof, wherein administration of the first composition sufficiently increases blood glucose level in the subject such that the second composition is not administered or the second composition is administered at a glucose infusion rate (GIR) of less than 8 mg/(kg*min).
