  • Publication number: 20210198339
    Abstract: The present disclosure provides conjugates that comprise an insulin molecule conjugated via a conjugate framework to two or more separate ligands that each include a saccharide, wherein the framework, ligand, saccharide and insulin molecule optionally comprise a fatty chain (e.g., a C8-30 fatty chain), wherein when said insulin molecule is conjugated both to a C8-30 fatty chain and one or more separate ligands that each include a saccharide, said C8-30 fatty chain is linked to insulin molecule only, and wherein when the framework or ligand comprises a fatty chain the insulin molecule is conjugated to two or more separate ligands. In certain embodiments, a conjugate is characterized in that, when the conjugate is administered to a mammal, at least one pharmacokinetic (PK) and/or pharmacodynamic (PD) property of the conjugate is sensitive to serum concentration of a second saccharide. In certain embodiments, a conjugate is also characterized by having a protracted PK profile.
