Patent number: 11820805Abstract: 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.Type: GrantFiled: December 13, 2018Date of Patent: November 21, 2023Assignee: MERCK SHARP & DOHME LLCInventors: Lin Yan, Pei Huo, Ahmet Kekec, Danqing D.

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. Exemplary conjugates and sustained release formulations are provided in addition to methods of use and preparation.Type: ApplicationFiled: December 13, 2018Publication date: June 17, 2021Applicants: Merck Sharp & Dohme Corp., SmartCells, Inc.Inventors: Lin Yan, Pei Huo, Ahmet Kekec, Yuping Zhu, Dmitri Pissarnitski, Danqing D.
