Abstract: The present invention relates to biological materials related to c-Met possibly in combination with VEGF and/or EGFR, and more in particular to polypeptides, nucleic acids encoding such polypeptides; to methods for preparing such polypeptides; to host cells expressing or capable of expressing such polypeptides; to compositions and in particular to pharmaceutical compositions that comprise such polypeptides, for prophylactic, therapeutic or diagnostic purposes. Methods and kits for assessing the responsiveness of a patient to c-Met therapy are also described and provided.

Abstract: This invention provides, and in certain specific but non-limiting aspects relates to: assays that can be used to predict whether a given ISV will be subject to protein interference as described herein and/or give rise to an (aspecific) signal in such an assay (such as for example in an ADA immunoassay).

Abstract: The present invention relates to amino acid sequences that block the interaction between (a target on) an antigen presenting cell (APC) and (a target on) a T-cell. More particularly, the present invention relates to amino acid sequences that are directed against (as defined herein) a target on an APC (also referred to herein as “APC target”) or a target on a T-cell (also referred to herein as “T-cell target”). The invention further relates to compounds or constructs, and in particular proteins and polypeptides, that comprise or essentially consist of one or more such amino acid sequences.

Abstract: The present invention relates to protein and polypeptide constructs that comprise single variable domains that are linked to an Fc portion. The immunoglobulin constructs comprise two polypeptide chains in which each polypeptide chain comprises two or more single variable domains that are linked, usually via a suitable hinge region or linker, to one or more constant domains that, together, form an Fc portion. The invention also relates to polypeptide chains that form part of such constructs and/or that can be used to form such constructs. The invention further relates to nucleotide sequences and nucleic acids that encode or can be used to express such constructs or polypeptide chains; to methods for producing such constructs and polypeptides chains; to compositions (and in particular pharmaceutical compositions) that comprise such constructs or polypeptide chains; and to uses of such constructs, polypeptide chains or compositions.

Abstract: The present invention relates to amino acid sequences that are directed against interleukin-6 (IL-6), as well as to compounds or constructs, and in particular proteins and polypeptides that comprise or essentially consist of one or more such amino acid sequences. The invention also relates to nucleic acids encoding such amino acid sequences and polypeptides to methods for preparing such amino acid sequences and polypeptides; to host cells expressing or capable of expressing such amino acid sequences or polypeptides; to compositions, and in particular to pharmaceutical compositions, that comprise such amino acid sequences, polypeptides, nucleic acids and/or host cells; and to uses of such amino acid sequences, polypeptides, nucleic acids, host cells and/or compositions, in particular for prophylactic, therapeutic or diagnostic purposes.

Abstract: The present invention relates to a method for generating or cloning a nucleic acid or nucleotide sequence that encodes a heavy chain antibody or an antigen-binding fragment thereof, wherein said heavy chain antibody or antigen-binding fragment is directed against a specific antigen, said method comprising the steps of providing a sample or population of cells from a Camelid immunized with said antigen, isolating from said sample or population said at least one cell that expresses or is capable of expressing a heavy chain antibody directed against said antigen, and obtaining from said at least one cell a nucleic acid or nucleotide sequence that encodes a heavy chain antibody directed against antigen or that encodes an antigen-binding fragment thereof directed against said antigen.
