Collagen peptide-based medicament compositions and devices and methods of production and use thereof
The present invention is in the fields of medicinal chemistry, biotechnology and pharmaceuticals. The invention provides compositions comprising one or more collagen mimetic peptides, optionally attached to one or more therapeutic compounds or one or more imaging compounds, for use in methods of treating, preventing, ameliorating, curing and diagnosing certain diseases and physical disorders in humans and veterinary animals, as well as methods of manufacturing such composition. The invention also provides medical devices comprising one or more such compositions of the invention. The invention also provides methods of use of such compositions and devices in treating and diagnosing certain diseases and physical disorders in humans and veterinary animals, including ocular diseases or disorders, skin diseases or disorders, certain cancers, particularly intraluminal cancers, gastrointestinal diseases or disorders, genitourinary tract diseases or disorders, fibrotic diseases/disorders and rheumatic diseases/disorders.

4. The composition of claim 3 , wherein said composition is formulation deliver the at least one CMP into the subconjunctival fornix.
5. The composition of claim 1 , wherein said composition is formulated as one or more drops of solution or a suspension that contains the composition.
6. The composition of claim 1 , wherein said composition is formulated for delivery via injection.
7. The composition of claim 1 , wherein said composition is formulated in the form of a coating on a solid material for implanting into an eye structure.
8. The composition of claim 1 , wherein said composition is formulated in the form of a wafer, film, gel, mesh or patch.
9. The composition of claim 1 , wherein said composition is attached to one or more spheres or nanoparticles for delivery to or into an eye structure.
10. The composition of claim 1 , wherein said collagen mimetic peptide is attached to at least one therapeutic compound (TC) to form a CMP-TC conjugate.
11. The composition of claim 10 , wherein said at least one therapeutic compound comprises at least one reactive hydroxyl group capable of being cross-linked to said collagen mimetic peptide.
12. The composition of claim 11 , wherein said at least one therapeutic compound is directly attached to said collagen mimetic peptide via an amino group on said collagen mimetic peptide linked to a hydroxyl group on said therapeutic compound.
13. The composition of claim 10 , wherein said at least one therapeutic compound is selected from the group consisting of a steroidal anti-inflammatory drug, a nonsteroidal anti-inflammatory drug, a topical anesthetic, a vitamin or a derivative or precursor thereof, therapeutic enzyme or a therapeutic fragment thereof, an antibiotic, a therapeutic monoclonal antibody or a therapeutic fragment thereof, a therapeutic fusion protein, a prostaglandin analogue, a growth factor, a neuropeptide, an α-adrenergic antagonist, a β-adrenergic antagonist, a cell surface receptor antagonist, a carbonic anhydrase inhibitor, and pharmaceutically acceptable salts, esters and derivatives thereof.
14. The composition of claim 13 , wherein said prostaglandin analogue is selected from the group consisting of latanoprost, travoprost, tafluprost, unoprostone, tatanoprostene bunod and bimatoprost, and pharmaceutically acceptable salts, esters and derivatives thereof.
15. The composition of claim 14 , wherein said prostaglandin analogue is latanoprost.
16. The composition of claim 10 , wherein said collagen mimetic peptide is covalently attached directly to said at least one therapeutic compound.
17. The composition of claim 10 , wherein said collagen mimetic peptide is indirectly attached to said at least one therapeutic compound via use of an attachment means.
18. The composition of claim 17 , wherein said attachment means comprises at least one polymeric chain having a first end and a second end.
19. The composition of claim 18 , wherein said polymeric chain is a linear polyethyleneglycol chain comprising at least four ethyleneglycol monomers.
20. The composition of claim 19 , wherein said polymeric chain comprises from twenty to twenty-five ethyleneglycol monomers.
21. The composition of claim 10 , wherein said collagen mimetic peptide comprises at least one biotin moiety and said therapeutic molecule comprises at least one avidin or streptavidin moiety, and wherein said biotin moiety on said collagen mimetic peptide binds to said avidin or streptavidin moiety on said therapeutic compound, thereby attaching said collagen mimetic peptide to said therapeutic compound.
22. The composition of claim 10 , wherein said collagen mimetic peptide comprises at least one avidin or streptavidin moiety and said therapeutic molecule comprises at least one biotin moiety, and wherein said avidin or streptavidin moiety on said collagen mimetic peptide binds to said biotin moiety on said therapeutic compound, thereby attaching said collagen mimetic peptide to said therapeutic compound.
