Binding proteins comprising a VL region paired with a VH region, and a CH1 region paired with a CL region, wherein the VL region and VH region comprise opposite charged mutations to facilitate pairing, and wherein the CH1 region and CL region comprise mutations to facilitate pairing, are provided. Binding proteins comprising one or more cysteine residues engineered into the VH/VL pair to form one or more disulfide bonds, are also provided. Multispecific binding proteins, nucleic acids encoding binding proteins and multispecific binding proteins, expression vectors, host cells, pharmaceutical composition and methods of treatment administering the binding proteins or multispecific binding proteins described herein are also provided.

Multispecific binding proteins with mutant fab domains

Provided herein are multispecific antibodies, e.g. bispecific antibodies, which are modified such that the desired chain pairing takes place and/or can be selected for. Specifically, this is achieved by using different dimerization domains for light chain pairing. Also disclosed herein are nucleic acids encoding for these antibodies, expression vectors comprising these nucleic acids, cells expressing them, and further to pharmaceutical compositions comprising the antibodies, as well as methods of isolating the antibodies.

Multispecific antibodies facilitating selective light chain pairing

Binding proteins comprising a pseudoFab domain including a stabilised knockout domain and a second VH/VL that form a first functional antigen binding domain are provided. Multispecific binding proteins comprising at least one pseudoFab are also provided. Multispecific binding proteins, nucleic acids encoding binding proteins and multispecific binding proteins, expression vectors, host cells, pharmaceutical composition and methods of treatment administering the binding proteins or multispecific binding proteins described herein are also provided.

PseudoFab-based multispecific binding proteins

The present invention concerns antibody-like binding protein specifically binding to CD3 and binding specifically to at least one further antigen, for example CD123. The present invention also concerns antibody-like binding protein specifically binding to CD123 and binding specifically to at least one further antigen. The invention further concerns anti-CD3 antibodies and anti-CD123 antibodies. The invention also relates to pharmaceutical compositions comprising the antibody-like binding protein, anti-CD3 antibodies or anti-CD123 antibodies of the invention, and their use to treat cancer. The invention further relates to isolated nucleic acids, vectors and host cells comprising a sequence encoding said antibody-like binding protein, anti-CD3 or anti-CD123 antibody and the use of said anti-CD123 antibody as a diagnostic tool.

Anti-CD3 antibodies, anti-CD123 antibodies and bispecific antibodies specifically binding to CD3 and/or CD123
