The present invention provides efficient methods based on alteration of the protein A-binding ability, for producing or purifying multispecific antibodies having the activity of binding to two or more types of antigens to high purity through a protein A-based purification step alone. The methods of the present invention for producing or purifying multispecific antibodies which feature altering amino acid residues of antibody heavy chain constant region and/or variable region. Multispecific antibodies with an altered protein A-binding ability, which exhibit plasma retention comparable or longer than that of human IgG1, can be efficiently prepared in high purity by introducing amino acid alterations of the present invention into antibodies.

The present invention relates to bispecific antibodies comprising a modified C-terminal crossfab fragment that have reduced or no reactivity against preexisting antidrug antibodies.

A Twin Immune Cell Engager (TWICE) is a kit or composition for treating cancer comprising a first component and second component. Each component comprises a targeting moiety that binds a tumor antigen expressed by the cancer or an antigen expressed by a non-cancer cell in the tumor microenvironment. In some embodiments, the first and second components each comprise an immune cell binding domain capable of immune cell binding activity when binding the immune cell binding domain in the other component, and a complementary binding domain capable of binding to a complementary antigen when binding the complementary binding domain in the other component. In some embodiments, the first and/or second components comprise a complementary functional domain with activity when targeted to the cancer cell or its microenvironment.

The present invention provides bispecific antibodies that bind to CD3 and tumor antigens and methods of using the same. According to certain embodiments, the bispecific antibodies of the invention exhibit reduced effector functions and have a unique binding profile with regard to Fcγ receptors. The bispecific antibodies are engineered to efficiently induce T cell-mediated killing of tumor cells. According to certain embodiments, the present invention provides bispecific antigen-binding molecules comprising a first antigen-binding domain that specifically binds human CD3, a second antigen-binding molecule that specifically binds human CD20, and an Fc domain that binds Fcγ receptors with a specific binding pattern. In certain embodiments, the bispecific antigen-binding molecules of the present invention are capable of inhibiting the growth of B-cell or melanoma tumors expressing CD20. The bispecific antibodies of the invention are useful for the treatment of various cancers as well as other CD20-related diseases and disorders.

The present disclosure provides methods for purifying multispecific antibodies from a mispaired variant thereof by performing a multi-mode chromatography.

The present invention generally relates to novel bispecific antigen binding molecules for T cell activation and re-direction to specific target cells. In addition, the present invention relates to polynucleotides encoding such bispecific antigen binding molecules, and vectors and host cells comprising such polynucleotides. The invention further relates to methods for producing the bispecific antigen binding molecules of the invention, and to methods of using these bispecific antigen binding molecules in the treatment of disease.

Binding molecules, including bispecific antibodies that include at least two anti-influenza binding domains are disclosed, including binding molecules having a first binding domain that specifically binds influenza A virus and a second binding domain that specifically binds influenza B virus.

The present invention provides novel antibodies that specifically bind to GUCY2c and uses thereof in the treatment of cancer. The present invention further provides novel bispecific antibodies comprising such antibodies and uses thereof in the treatment of cancer.

The invention relates to a truncated multivalent multimer comprising two or more binding domains, wherein each binding domain binds a different antigen or epitope, and wherein two of said binding domains are paired via a hinge region, wherein the multimer lacks a CH2 or CH3 region. The present invention further comprises two polypeptides that are paired at or near their respective C-terminus comprising two or more disulfide bridges, wherein each of said polypeptide comprise a variable binding domain, comprising a variable region, wherein each variable region binds the same or different antigens or epitopes on an antigen.

Described herein are hybrid antibodies targeted for use in the treatment of cancer. The antibodies have binding capabilities for Fcε receptors and the neonatal Fc receptor, which may be achieved e.g. by replacing sequences or amino acids in IgE constant domain with corresponding sequences and amino acids derived from IgG.
