The present invention relates to a trivalent binding molecule comprising a first polypeptide comprising two binding domains and a second polypeptide comprising a third binding domain. The present invention further relates to the trivalent binding molecule for use in medicine and in particular in the prophylaxis, treatment or diagnosis of a disorder or disease.

A bivalent, anti-MICA human monoclonal antibody formed by two or more heavy and light chains with a variable immunoglobulin domain neutralises the MICA protein in its soluble state and opsonises tumour cells expressing the antigen, stimulating adaptive immunity in the treatment of gastric cancer or other types of cancer in which the tumour cells express MICA in the soluble form or abundantly on their surface.

The present invention relates to the field of single-domain antibodies (sdAb) directed towards the glycans of the globo series, and in particular Globo H. More in detail, the present invention relates to sdAbs specifically binding one or more glycans selected from Globo H, Gb3, Gb4, and Gb5. The invention also provides polypeptides comprising multimeric single domain antibodies, as well as T cell chimeric antigen receptors comprising said anti-glycan sdAbs. Thus, the present invention provides polypeptides that can be used for targeting and/or treating several types of cancers associated with cells over-expressing said Globo H and/or Gb3, Gb4, Gb5. The present invention also relates to recombinant nucleic acid sequences encoding said polypeptides, and expression vectors and host cells comprising the same.

The present invention relates to the field of structural biology. More specifically, the present invention relates to an antigen-binding chimeric protein, called a MegaBody™, specifically binding a nanodisc, more specifically a membrane-scaffold protein (MSP)n which may be part of the nanodisc. The invention further provides for methods and uses of said nanodisc-specific antigen-binding chimeric proteins in three-dimensional high-resolution structural analysis of membrane proteins assembled within nanodiscs. The MSP-binding MegaBodies of the invention provide for a generic tool in membrane protein structural biology, more particular in Cryo-EM, by reducing preferred particle orientation of nanodiscs and of the entrapped target membrane proteins.

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.

The present invention relates to the treatment of subjects having CD20-positive cell proliferative disorders (e.g., B cell proliferative disorders, such as non-Hodgkin's lymphomas). More specifically, the invention pertains to the treatment of subjects having a CD20-positive cell proliferative disorder (e.g., B cell proliferative disorder) by administering a combination of an anti-CD20/anti-CD3 bispecific antibody and an anti-CD79b antibody drug conjugate.

Antigen binding proteins that specifically recognize a target Melanoma-Associated Antigen A4 (MAGE-A4) peptide-MHC (pMHC), and nucleic acids encoding the same, are provided. Methods of producing antigen binding proteins that specifically recognize a target MAGE-A4 pMHC, and nucleic acid libraries encoding the same, are also provided.

The present disclosure provides isolated binding proteins such as humanized antibodies and antigen-binding fragments thereof that target alpha-synuclein, including multispecific isolated binding proteins that target both alpha-synuclein and insulin-like growth factor 1 receptor. Also provided are methods of using the binding proteins to treat alpha-synucleinopathies.

Isolated monoclonal antibodies which bind to human c-Met, the hepatocyte growth factor receptor, and related antibody-based compositions and molecules, are disclosed. Pharmaceutical compositions comprising the antibodies and therapeutic and diagnostic methods for using the antibodies are also disclosed.

An antibody that binds a glycosylated protein is disclosed, wherein the glycosylation comprises the glycan motif Fucα1-2Galβ1-3GlcNAcβ1-3Galβ1 or Fucα1-2Galβ1-3GlcNAc. Antibodies that are cytotoxic against undifferentiated pluripotent cells are also disclosed.
