Publication number: 20220273770Abstract: Glucose-responsive insulin conjugates that contain one or more trisaccharides are provided. Such insulin conjugates may display a pharmacokinetic (PK) and/or pharmacodynamic (PD) profile that is responsive to the systemic concentrations of a saccharide such as glucose or alpha-methylmannose, even when administered to a subject in need thereof in the absence of an exogenous multivalent saccharide-binding molecule.Type: ApplicationFiled: July 23, 2020Publication date: September 1, 2022Applicant: Merck Sharp & Dohme Corp.Inventors: Danqing Feng, Erin N. Guidry, Pei Huo, Andrew J. Kassick, Ahmet Kekec, Songnian Lin, Christopher R. Moyes, Dmitri A. Pissarnitski, Lin Yan, Yuping Zhu

Publication number: 20210198339Abstract: 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: ApplicationFiled: December 13, 2018Publication date: July 1, 2021Applicant: Merck Sharp & Dohme Corp.Inventors: Lin Yan, Pei Huo, Ahmet Kekec, Danqing D. Feng, Yuping Zhu, Dmitri Pissarnitski, Chris Moyes, Songnian Lin
