The consortium aims to develop and produce an Anticalin, a member of a novel high-affinity scaffold derived from the lipocalin protein family. The Anticalin is specific for hepcidin which is a central regulator of iron homeostasis, and will be used to antagonize hepcidin for the treatment of anemia of chronic disease (ACD). Anticalins are genetically modified lipocalins that can target almost any desired molecule. Unlike Immunoglobulins, they can be produced at low cost in microbial expression systems, are expected to be non immunogenic and offer therapeutic advantages where antibody effector functions are not desired. ACD, the most frequent anemia in hospitalized patients, develops in subjects suffering from infections, inflammatory and auto-immune disease, cancer and chronic kidney disease. It is often successfully treated by administering Erythropoiesis-Stimulating Agents. However, a significant number of patients are hypo- or non-responsive to ESA. Anti-hepcidin therapies, alone or together with ESAs, may improve anemia and the patients erythropoietic response and enable the use of no or even much lower ESA doses, avoiding the potential detrimental effects of high doses of ESA. The Consortium has already generated proof-of-concept data in an animal model with early candidates. The project aims at identifying, validating, and developing a specific, high affinity drug candidate based on the lipocalin scaffold as promising alternatives to immunoglobulins and a therapeutic approach based on the neutralization of hepcidin. Animal models will be developed and utilized to characterize pharmacokinetic and pharmacodynamic relationships, optimize dosing, to determine safety, biomarker responses and potential synergy with ESAs. Furthermore, production processes will be optimized leading to a scalable GMP process which provides material for preclinical and clinical studies to establish the safety, tolerability, and PK/PD of an Anticalin hepcidin blocker (Phase Ia/b).


The present invention relates to novel, specific-binding therapeutic and/or diagnostic proteins directed against Hepcidin, which proteins preferably are muteins of lipocalin protein. The invention also relates to nucleic acid molecules encoding such proteins and to methods for generation and use of such proteins and nucleic acid molecules. Accordingly, the invention also is directed to pharmaceutical and/or diagnostic compositions comprising such a lipocalin proteins, including uses of these proteins.


The present invention relates to a novel library for the generation of muteins and to novel muteins derived from human lipocalin 2 (Lcn2, hNGAL) and related proteins that bind a given target with detectable affinity. The invention also relates to corresponding nucleic acid molecules encoding such a mutein and to a method for their generation. The invention further relates to a method for producing such a mutein. For example, such muteins may serve to bind and deplete pathological forms of natural biomolecules such as the amyloid beta peptide in Alzheimers disease or may target the fibronectin extra-domain B, which is associated with tumor neovasculature.


The present invention relates to a mutein derived from human neutrophil gelatinase-associated lipocalin (hNGAL) with affinity for the cytotoxic T lymphocyte associated antigen (CTLA-4) of K_(D) 50 nM or less. The present invention also relates to nucleic acid molecules encoding such muteins, as well as host cells comprising such nucleic acid molecules. The present invention further relates to pharmaceutical compositions and diagnostic or analytical kits comprising said mutein.

The invention relates to the production of novel proteins exhibiting bonding activity for certain ligands, the so-called anticalins. To this end, the structure of peptides of the lipocalin family is modified by amino acid replacement in their natural ligand binding pocket using generic engineering methods. A like immunoglobulin, the anticalin thus obtained can be used to identify or bond molecular structures.
