Provided herein are conjugates comprising a protein and an oligosaccharide of one of Formulae I-VI. Also provided herein are pharmaceutical compositions comprising such conjugates. Further provided herein are methods of treating a lysosomal storage disorder in a mammal by administration of an oligosaccharide-glycoprotein conjugate.

Oligosaccharide-protein conjugates

The current disclosure provides binding polypeptides (e.g., antibodies), and effector moiety conjugates thereof (e.g., antibody-drug conjugates or ADCs), comprising a site-specifically engineered drug-glycan linkage within native or engineered glycans of the binding polypeptide. The current disclosure also provides nucleic acids encoding the antigen-binding polypeptides, recombinant expression vectors and host cells for making such antigen-binding polypeptides. Methods of using the antigen-binding polypeptides disclosed herein to treat disease are also provided.

Site-specific antibody-drug conjugation through glycoengineering

Engineered antibodies that are stable and can be conjugated to a ligand or drug at a ligand/drug to antibody ratio of above 3, making these conjugates suitable for treatment of a variety of indications, are provided. Methods of producing these engineered antibodies are also provided.

Modified binding polypeptides for optimized drug conjugation

The current disclosure provides binding polypeptides (e.g., antibodies), and targeting moiety conjugates thereof, comprising a site-specifically engineered glycan linkage within native or engineered glycans of the binding polypeptide. The current disclosure also provides nucleic acids encoding the antigen-binding polypeptides, recombinant expression vectors and host cells for making such antigen-binding polypeptides. Methods of using the antigen-binding polypeptides disclosed herein to treat disease are also provided.

Site-specific glycoengineering of targeting moieties

Glycoengineered antibody drug conjugates

The current disclosure provides binding polypeptides (e.g., antibodies), and effector moiety conjugates thereof (e.g., antibody-drug conjugates or ADCs), comprising a site-specifically engineered drug-glycan linkage within native or engineered glycans of the binding polypetpide. The current disclosure also provides nucleic acids encoding the antigen-binding polypeptides, recombinant expression vectors and host cells for making such antigen-binding polypeptides. Methods of using the antigen-binding polypeptides disclosed herein to treat disease are also provided.

Methods for producing antibody-based therapeutics with enhanced ADCC activity are disclosed. The enhanced ADCC activity is attributed to oligomannose-type N-glycans on the antibodies and Fc fusion proteins of the invention. Also disclosed are methods of using such antibody-based therapeutics for targeted killing of cells in a mammal, including therapeutic methods of treating cancers, autoimmune diseases and other diseases.
