Definitions

  • the present invention relates to recombinant type II collagen for use in a therapeutic method for the oral therapy of cartilage diseases in a human or animal body.
  • Collagen is an extracellular structural protein found in animals such as mammals, birds and fish. It is usually found there in the connective tissue, particularly as a component of the extracellular matrix. Tendons, ligaments, cartilage and bones are particularly rich in collagen. In contrast, collagens are not naturally found in plants and unicellular organisms.
  • Collagens occur in different, structurally and functionally different types and differ in terms of their structure, function and origin, among other things.
  • the polypeptide chains building up the collagen are synthesized individually in the cell on the ribosomes of the endoplasmic reticulum in the form of larger precursor molecules and have extensive repetitive (Gly-X-Y)n sequences, where X and Y can be any amino acid, but mostly proline and 4- are hydroxyproline.
  • precursor polypeptide chains are post-translationally hydroxylated to proline and fysine residues of the polypeptide chain in the endoplasmic reticulum to form hydroxyproline and hydroxylysine residues.
  • the hydroxylation serves to stabilize neighboring collagen polypeptide chains of the right-hand triple helix formed in the cell, each consisting of three of the precursor polypeptide chains (procollagen).
  • the procollagen formed in this way is glycosylated intracellularly, secreted from the cell in the glycosylated triple-helical form (tropocollagen) and then mature collagen is formed by peptidase-mediated cleavage of the terminal residues. As part of a fibrillogenesis process, this accumulates to form collagen fibrils, which are then covalently cross-linked and form collagen fibers.
  • Collagen is also often used in denatured form, sometimes also referred to as gelatine, or in the form of its hydrolyzates. If gelatine or collagen is subjected to hydrolytic processes, in particular an enzymatic hydrolysis, to obtain collagen peptides, collagen hydrolysates with a wide variety of compositions and application profiles can be produced depending on the collagen type used and origin as well as the enzymatic conditions. However, these collagen hydrolysates represent a mixture of peptides whose molecular weights are distributed over certain size ranges. The use of such collagen hydrolyzates, for example as a dietary supplement or as a cosmetic aid, has been known for a long time, among other things for the prevention and/or treatment of complaints associated with the bones, the joints or the connective tissue.
  • WO 2012/065782 describes collagen hydrolyzates obtained from pigskin gelatine, which are used to stimulate the biosynthesis of extracellular matrix proteins by skin cells and are particularly suitable for cosmetic purposes.
  • WO 2012/117012 discloses enzymatically hydrolyzed collagen from bovine splits with an average molecular weight of 1500 to 8000 Da, which can be used together with a prebiotic to prevent and/or treat osteoporosis.
  • collagen hydrolysates obtained from animal materials has advantages for many applications and consumer groups, the use of collagen hydrolysates obtained in this way can also be less desirable with regard to certain consumer groups and application profiles.
  • Certain consumer groups are fundamentally critical or hostile to raw materials derived from animal materials, whether they fear contamination with harmful microorganisms or agents, such as processing aids, or unwanted immune reactions, or for religious or ethical reasons.
  • the manufacturing processes used to obtain collagen hydrolyzates obtained from animal materials often include complex and expensive disruption, purification and further processing steps.
  • WO 2006/052451 A2 discloses the production of recombinant type III collagen in Pichia pastoris strains which also express human prolyl hydroxylases.
  • WO 2005/012356 A2 discloses the production of gelatin from human collagen type I and individual 50 kDa, 65 kDa and 100 kDa collagen peptide species in fully hydroxylated, partially and non-hydroxylated forms, respectively.
  • Olsen et al. Provides the recombinant production of an 8.5 kDa collagen peptide species from the a1 chain of human collagen in Pichia pastoris.
  • WO 01/34646 A2 also discloses the production of individual recombinant gelatin species with a defined molecular weight of up to 350 kDa resulting from the recombinant production route, which can be present in non-hydroxylated, partially or completely hydroxylated form.
  • Type II collagen is a collagen that occurs specifically in cartilage tissue and is usually present there in the form of a homotrimer of a1 chains.
  • the production of recombinant type II collagen peptides, their hydroxylation by means of a prolyl-4-hydroxylase and their hydrogenation and formation into procollagen and the associated triple helix formation is described, for example, in US Pat. No. 5,593,859.
  • US Pat. No. 5,399,347 describes the oral administration of water-soluble, highly purified type II collagen from natural sources for the treatment of arthritis.
  • the production of this collagen is extremely difficult, expensive and also susceptible to contamination, in particular from microbes.
  • US 7,083,820 and EP 1 435 906 disclose the use of methods for obtaining animal tissue-containing compositions containing non-denatured type II collagen, with special process steps eliminating microbial contaminants, but at the same time the original, non-denatured form of the Type II collagen should be preserved.
  • the present invention is therefore based on the technical problem of providing type II collagen that overcomes the aforementioned disadvantages, in particular that can be produced in a standardized, reliable and precisely defined form, even on a larger industrial and cost-effective scale, and because of its biological effectiveness for use in a method for the oral therapy of cartilage diseases in the human or animal body and/or for maintaining cartilage health.
