The disclosure provides radiolabeled and/or cytotoxin labelled antibodies and methods and uses of these antibodies. In one embodiment, provided is a cytotoxic agent comprising an antibody that specifically binds a target disease cell surface receptor, a cytotoxin, and a radiolabel, wherein the cytotoxin is linked directly or indirectly to the antibody, and wherein the radiolabel comprises a radionuclide and optionally a scaffold, wherein the scaffold is directly or indirectly coupled to the antibody. Also provided are methods of preparing the cytotoxic agent and methods of treating disease using the cytotoxic agent.

Combination therapies comprising administering radioimmunoconjugates and DNA damage response inhibitors.

Combination therapies comprising administering radioimmunoconjugates and one or more checkpoint inhibitors.

The present invention relates to positions in the constant region of antibodies, in particular the CH3 region of IgG4, which affect the strength of CH3-CH3 interactions. Mutations that either stabilize or destabilize this interaction are disclosed.

The present invention relates to dimers comprising a first polypeptide and a second polypeptide, wherein each of said first and second polypeptide comprises at least one immunoglobulin single variable domain (ISVD) and a C-terminal extension comprising a cysteine moiety (preferably at the C-terminus), wherein said first polypeptide and said second polypeptide are covalently linked via a disulfide bond between the cysteine moiety of said first polypeptide and the cysteine moiety of said second polypeptide, in which the dimer outperformed the benchmark constructs, e.g. cognate multivalent and multispecific constructs, in various assays. The present invention provides methods for making the dimers of the invention.

The present invention relates to a combination of radioimmunoconjugates and a protein or molecule capable of leading to progression of the cell cycle through the G2/M checkpoint, a protein or molecule capable of inhibiting progression through Mitosis, a protein or molecule which is a BCL2 inhibitor, or a protein or molecule which is a PARP inhibitor, for use as a medicament. The medicament may be against Non-Hodgkin's lymphoma (NHL).

The present invention relates to novel stabilized IgG4 antibodies, to methods of producing such antibodies and to uses of such antibodies as a medicament. In a main aspect, the invention relates to a stabilized IgG4 antibody, comprising a heavy chain and a light chain, wherein said heavy chain comprises a human IgG4 constant region having a substitution of the Arg residue at position (409), the Phe residue at position (405) or the Lys residue at position (370).

The present invention relates to conjugates including a residualizing linker, methods for their production, and uses thereof.

Radiolabeled anti-MET antibodies and METMET bispecific antibodies and their use in immuno-PET imaging are provided herein. Included are methods of detecting the presence of MET proteins in a subject or sample and methods of monitoring efficacy of treatment of a Met expressing tumor.

The present invention relates to specific binding members, particularly antibodies and fragments thereof, which bind to amplified epidermal growth factor receptor (EGFR) and to the de2-7 EGFR truncation of the EGFR. In particular, the epitope recognized by the specific binding members, particularly antibodies and fragments thereof, is enhanced or evident upon aberrant post-translational modification. These specific binding members are useful in the diagnosis and treatment of cancer. The binding members of the present invention may also be used in therapy in combination with chemotherapeutics or anti-cancer agents and/or with other antibodies or fragments thereof.
