An antibody-drug conjugate (ADC) or a pharmaceutically acceptable salt thereof, is provided. The ADC includes a tetravalent monoclonal antibody conjugated to a cytotoxic drug by a chemical linker. The monoclonal antibody includes two long chains and four short chains. Each of the long chains includes a first segment and a second segment, the first segment located proximal to the N-terminus of the long chain, and the second segment located proximal to the C-terminus of the long chain. Each of the first segment and second segment pairs with one of the short chains to form an antigen-binding fragment domain, therefore forming four antigen-binding fragment domains having specificity toward the same antigen. Pharmaceutical composition including the ADC and methods of treating diseases using the compositions are also provided.

Tetravalent antibody-drug conjugates and use thereof

The present invention relates to novel respiratory syncytial virus (RSV) F peptides and compositions comprising them. The present invention also relates to methods of evaluating anti-RSV antibody binding to F peptides. The present invention also relates to antibodies that immunospecifically bind to an F peptide of the present invention. The invention further provides methods and protocols for the administration of F peptides and/or antibodies that immunospecifically bind to F peptides for the prevention, neutralization, treatment of RSV infection. Additionally, the methods of the invention may be useful for the treatment, prevention and the amelioration of symptoms associated with RSV infection.

Antibodies against and methods for producing vaccines for respiratory syncytial virus

The present invention provides macromolecules comprising at least one thioether cross-link. A thioether cross-link comprising a single thioether bond between two residues of a macromolecule. The macromolecules of the invention can display enhanced stability, pharmaceutical properties and functional properties. In particular, the invention provides an isolated antibodies comprising at least one thioether cross-link that specifically bind to particular antigens. The present invention also provides a composition comprising a macromolecule substantially free of a denaturing reagent, wherein the macromolecule comprises at least one thioether cross-link. In addition, the present invention provides a method for producing the macromolecules and compositions of the invention.
