The invention provides an anti-PD-1 antibody comprising the complementary determining regions (CDRs) of pembrolizumab in combination with an antibody-drug conjugate that binds to tissue factor (TF) comprising monomethyl auristatin E and the CDRs of tisotumab (e.g., tisotumab vedotin) and their use in methods of treating cancer, such as breast cancer and cervical cancer. The invention also provides compositions and kits comprising the anti-PD-1 antibody comprising the CDRs of pembrolizumab and the antibody-drug conjugate that binds to TF comprising monomethyl auristatin E and the CDRs of tisotumab (e.g., tisotumab vedotin) for use in treating cancer, such as breast cancer and cervical cancer.

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 a low-molecular antibody composed of D-amino acids and achiral glycine, a method for producing the same, and a method for screening the low-molecular antibody using a mirror-image target protein corresponding to a target protein and an antibody library.

The invention also relates to antigen binding proteins and related fragments thereof for binding Von Willebrand factor (VWF) and uses thereof. In one aspect, the present invention provides an antigen binding protein comprising an antigen binding domain that binds to or specifically binds to Von Willebrand factor (VWF) under shear gradient conditions. Preferably, the antigen binding protein comprises an antigen binding domain that does not bind to VWF under constant shear conditions.
