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

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

The present invention discloses novel antibodies that specifically bind to the human platelet membrane protein Glycoprotein VI (GPVI) and their monovalent fragments or derivatives. The antibodies of the invention are antibodies from hybridoma clone 390 and fragment antibodies thereof able to induce a GPVI depletion phenotype. These antibodies and Fab fragments are able to block collagen binding and thus preventing platelet activation by collagen. The invention also relates to hybridoma clones and expression plasmids for the production of disclosed antibodies and Fab fragments. The present invention further refers to the uses of monovalent antibody fragments to manufacture research, diagnostic and immunotherapeutic agents for the treatment of thrombosis and other vascular diseases. The invention also concerns a Fab bearing a molecule at the C-terminal extremity, as well as method for prevention of recognition of Fab by antibodies using such modified Fab. The invention concerns a method for prevention of platelet activation when an anti-GP VI Fab is used.
