There are provided inter alia polypeptides capable of inhibiting IL-7 and/or L-TSLP binding to IL-7R (IL-7R), as well as to constructs and pharmaceutical compositions comprising these polypeptides.

Polynucleotides encoding, and method of making, a polypeptide comprising a VHH which binds interleukin-receptor (IL-7R)

There is provided inter alia a construct suitable for oral administration comprising a first polypeptide and a second polypeptide connected by a labile peptide linker, wherein the labile peptide linker is labile to one or more proteases present in the intestinal tract and wherein the first and second polypeptides are substantially resistant to said one or more proteases.

Peptide construct having a protease-cleavable linker

Described herein is a polypeptide comprising an immunoglobulin chain variable domain comprising three complementarity determining regions (CDR1-CDR3) and four framework regions, wherein: (a) at least one lysine residue in CDR1, CDR2 and/or CDR3 has been substituted with at least one histidine residue, and/or (b) at least one arginine residue in CDR1, CDR2 and/or CDR3 has been substituted with at least one histidine residue. The polypeptides of this disclosure possess increased intestinal stability relative to a corresponding polypeptide not having the histidine substitutions.

Polypeptides

There is provided inter alia a polypeptide comprising an immunoglobulin chain variable domain which binds to IL-6R, wherein the immunoglobulin chain variable domain comprises three complementarity determining regions (CDR1-CDR3) and four framework regions (FR1-FR4), wherein CDR1-CDR3 and FR1-FR4 are as defined in the specification.

Polypeptides comprising immunoglobulin chain variable domains which bind to interleukin-6 receptor (IL-6R) and methods of use thereof to treat autoimmune and inflammatory diseases

There is provided inter alia a composition comprising a TNF-alpha binding polypeptide and an IL-6R binding polypeptide.

Compositions

VHH immunoglobulin chain variable domain that binds to IL-7R and methods of use thereof for treating autoimmune and/or inflammatory diseases

There is provided inter alia a polypeptide comprising an immunoglobulin chain variable domain which binds to IL-23, wherein the immunoglobulin chain variable domain comprises three complementarity determining regions (CDR1-CDR3) and four framework regions (FR1-FR4), wherein CDR1 comprises a sequence sharing 60% or greater sequence identity with SEQ ID NO: 1, CDR2 comprises a sequence sharing 50% or greater sequence identity with SEQ ID NO: 2 and CDR3 comprises a sequence sharing 50% or greater sequence identity with SEQ ID NO: 3.

IL-23 and TNF-alpha binding bi-specific heavy chain polypeptides

Polypeptides which bind to interleukin-6 receptor (IL-6R)

There is provided a solid pharmaceutical composition for delivering by oral administration a pharmaceutically active binding polypeptide to a region of the intestinal tract comprising a compressed core, wherein the compressed core comprises a pharmaceutically active binding polypeptide and wherein the compressed core is coated with a pH sensitive enteric coating.

There is provided inter alia a polypeptide comprising an immunoglobulin chain variable domain which binds to TNF-alpha, wherein the immunoglobulin chain variable domain comprises three complementarity determining regions (CDR1-CDR3) and four framework regions (FR1-FR4), wherein CDR1-CDR3 and FR1-FR4 are as defined in the specification.
