The present technology aims at providing a novel type of drug for treating a subject suffering from an inflammatory disease. Specifically, the present technology provides polypeptides comprising at least four immunoglobulin single variable domains (ISVDs), characterized in that at least two ISVDs bind to IL-13 and at least two ISVDs binds to TSLP. The present technology also provides nucleic acids, vectors and compositions.

Nucleic acids encoding polypeptides comprising immunoglobulin single variable domains targeting IL-13 and TSLP

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.

PD1 and/or LAG3 binders

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). Such predictive assays could for example be used to test whether a given ISV could have a tendency to give rise to such protein interference and/or such a signal; to select ISV's that are not or less prone to such protein interference or to giving such a signal; as an assay or test that can be used to test whether certain modification(s) to an ISV will (fully or partially) reduce its tendency to give rise to such interference or such a signal; and/or as an assay or test that can be used to guide modification or improvement of an ISV so as to reduce its tendency to give rise to such protein interference or signal;—methods for modifying and/or improving ISV's to as to remove or reduce their tendency to give rise to such protein interference or such a signal;—modifications that can be introduced into an ISV that remove or reduce its tendency to give rise to such protein interference or such a signal; ISV's that have been specifically selected (for example, using the assay(s) described herein) to have no or low(er)/reduced tendency to give rise to such protein interference or such a signal; modified and/or improved ISV's that have no or a low(er)/reduced tendency to give rise to such protein interference or such a signal.

Techniques for predicting, detecting and reducing aspecific protein interference in assays involving immunoglobulin single variable domains

Methods of treating asthma with polypeptides targeting IL-13 and TSLP

The present invention provides molecules, such as ISVDs and Nanobodies, that bind to CTLA4 or 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.

CTLA4 binders

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). Such predictive assays could for example be used to test whether a given ISV could have a tendency to give rise to such protein interference and/or such a signal; to select ISV's that are not or less prone to such protein interference or to giving such a signal; as an assay or test that can be used to test whether certain modification(s) to an ISV will (fully or partially) reduce its tendency to give rise to such interference or such a signal; and/or as an assay or test that can be used to guide modification or improvement of an ISV so as to reduce its tendency to give rise to such protein interference or signal; methods for modifying and/or improving ISV's to as to remove or reduce their tendency to give rise to such protein interference or such a signal; modifications that can be introduced into an ISV that remove or reduce its tendency to give rise to such protein interference or such a signal; ISV's that have been specifically selected (for example, using the assay(s) described herein) to have no or low(er)/reduced tendency to give rise to such protein interference or such a signal; modified and/or improved ISV's that have no or a low(er)/reduced tendency to give rise to such protein interference or such a signal.

The present invention relates to polypeptides directed against or specifically binding to C&#x2014;X&#x2014;C Motif chemokine receptor 2 (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.

Chemokine receptor binding polypeptides

Polypeptides are provided that are capable of significantly inhibiting and/or neutralizing. The polypeptides comprise two or more immunoglobulin single variable domains that are directed against the PcrV protein of, wherein the 'first' immunoglobulin single variable domain and the 'second' immunoglobulin single variable domain have different paratopes.
