The present invention relates to designed ankyrin repeat domains with altered surface residues, as well as to proteins comprising such a designed ankyrin repeat domain, nucleic acids encoding such domains or proteins, methods of preparing such proteins, pharmaceutical compositions comprising such proteins or nucleic acids, and the use of such proteins, nucleic acids or pharmaceutical compositions in the treatment of diseases.

Designed ankyrin repeat domains with altered surface residues

New designed ankyrin repeat domains with binding specificity for serum albumin, recombinant binding proteins comprising at least two designed ankyrin repeat domains with binding specificity for serum albumin, as well as recombinant binding proteins comprising at least one designed ankyrin repeat domain with binding specificity for hepatocyte growth factor (HGF), at least one designed ankyrin repeat domain with binding specificity for vascular endothelial growth factor (VEGF-A), and at least two designed ankyrin repeat domain with binding specificity for serum albumin are described, as well as nucleic acids encoding such designed ankyrin repeat domains and recombinant binding proteins, pharmaceutical compositions comprising such designed ankyrin repeat domains, recombinant binding proteins or nucleic acids and the use of such designed ankyrin repeat domains, recombinant binding proteins, nucleic acids or pharmaceutical compositions in the treatment of diseases.

Recombinant binding proteins and their use

The present invention relates to binding proteins specific for VEGF-A, in particular to recombinant binding proteins comprising a polyethylene glycol moiety and a binding domain, which inhibits VEGF-Axxx binding to VEGFR-2. Examples of such recombinant binding proteins are proteins which comprise an ankyrin repeat domain with the desired binding specificity, and a polyethylene glycol moiety. The binding proteins are useful in the treatment of cancer and other pathological conditions, e.g. eye diseases such as age-related macular degeneration.

Modified binding proteins inhibiting the VEGF-A receptor interaction

Improved N-terminal capping modules for designed Ankyrin repeat proteins (DARPins) conferring improved thermal stability to the DARPins are described, as well as nucleic acids encoding such proteins, pharmaceutical compositions comprising such proteins and the use of such proteins in the treatment of diseases.

Capping modules for designed ankyrin repeat proteins

New designed repeat proteins with binding specificity for serum albumin are described, as well as nucleic acids encoding such serum albumin binding proteins, pharmaceutical compositions comprising such proteins, the use of such proteins to modify the pharmacokinetics of therapeutic relevant polypeptides and the use of such proteins in the treatment of diseases. The repeat proteins of the invention have a substantially increased half-life in plasma compared to proteins not binding serum albumin.

Designed repeat proteins binding to serum albumin

A repeat protein from a collection of repeat proteins, wherein each repeat protein of said collection comprises a repeat domain, which comprises a set of consecutive repeat modules, wherein the repeat modules have the same fold and stack tightly to create a superhelical structure having a joint hydrophobic core, wherein each of the repeat modules is derived from one or more repeat units and wherein the repeat units comprise framework residues, which contribute to the folding topology of the repeat unit or contribute to an interaction with a neighboring repeat unit, and target interaction residues, which contribute to an interaction with a target substance, wherein the repeat proteins of the collection differ from other repeat proteins in the collection in at least one amino acid position of the repeat modules is described as are related pharmaceuticals and nucleic acid molecules.

Repeat protein from collection of repeat proteins comprising repeat modules

Recombinant proteins that simultaneously bind HGF, VEGF-A and serum albumin, comprising ankyrin repeat domains

The present invention relates to binding proteins specific for Vascular Endothelial Growth Factor A (VEGF-A), in particular to recombinant binding proteins comprising a polyethylene glycol moiety and a binding domain, which inhibits VEGF-Axxx (wherein xxx denotes the amino acid length of the VEGF-A mature protein) binding to Vascular Endothelial Growth Factor Receptor 2 (VEGFR-2). Examples of such recombinant binding proteins are proteins which comprise an ankyrin repeat domain with the desired binding specificity, and a polyethylene glycol moiety. The binding proteins are useful in the treatment of cancer and other pathological conditions, e.g. eye diseases such as age-related macular degeneration.

Improved N-terminal capping modules for designed ankyrin repeat proteins (DARPins) conferring improved thermal stability to the DARPins are described, as well as nucleic acids encoding such proteins, pharmaceutical compositions comprising such proteins and the use of such proteins in the treatment of diseases.
