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 polypeptides directed against or specifically binding to chemokine receptor CXCR2 and in particular to polypeptides capable of modulating signal transduction from CXCR2. The invention also relates to nucleic acids, vectors and host cells capable of expressing the polypeptides of the invention, pharmaceutical compositions comprising the polypeptides and uses of said polypeptides and compositions for treatment of diseases involving aberrant functioning of CXCR2.

Abstract: The present invention provides multispecific molecules, e.g., comprising more than one ISVD or Nanobody, that bind to PD1 and CTLA4. These molecules have been engineered so as to reduce the incidence of binding by pre-existing antibodies in the bodies of a subject administered such a molecule. Methods for increasing immune response, treating cancer and/or treating an infectious disease with such molecules are provided.

Abstract: The present invention provides molecules, such as ISVDs and Nanobodies, that bind to PD1 and LAG3 and, optionally to human serum albumin. These molecules have been engineered so as to reduce the incidence of binding by pre-existing antibodies in the bodies of a subject administered such a molecule. Methods for increasing immune response, treating cancer and/or treating an infectious disease with such molecules are provided.

Abstract: Biparatopic protein constructs that are directed against IL-23, and in particular against the p19 subunit of IL-23. The constructs comprise at least a first binding domain or binding unit directed against a first defined epitope on p19 and at least a second binding domain or binding unit directed against a second defined epitope on p19 (or the p19/p40 interface). The binding domains or binding units may in particular be a domain antibody, a single domain antibody, a dAb or a Nanobody®. The constructs and pharmaceutical compositions comprising the same can be used for the prevention and/or treatment of diseases and disorders associated with IL-23 or IL-23 mediated signaling, such as inflammation and inflammatory disorders such as colitis, Crohn's disease and IBD, infectious diseases, psoriasis, cancer, autoimmune diseases, sarcoidosis, transplant rejection, cystic Fibrosis, asthma, chronic obstructive pulmonary disease, rheumatoid arthritis, viral infection, and common variable immunodeficiency.
