Ophthalmic compositions and methods of use therefor
The present invention encompasses ophthalmic compositions that may be used for various conditions of the eye, and particularly, conditions of the cornea. Also encompassed are methods that utilise these compositions and kits that include these compositions.
1. A kit comprising:
(i) a composition comprising a TGFβ3 polypeptide which comprises the amino acid sequence of SEQ ID NO:1 or which is at least 90% identical to the amino acid sequence of SEQ ID NO:1, and dexamethasone or derivative thereof or a related steroidal agent; and
(ii) one or more contact lenses, corneal inserts, corneal implants, or intrastromal rings;
wherein the kit is adapted to be used in:
(a) treating or preventing progression of a refractive error of an eye;
(b) treating or preventing progression of a condition associated with thinning or irregularity of a cornea; or
(c) treating or preventing progression of a corneal condition selected from the group consisting of: keratoconus, myopia, hyperopia, astigmatism, presbyopia, and stromal dystrophies;
and wherein use of the kit in any of (a), (b), or (c) does not result in scarring in the cornea or in the eye.
2. The kit of claim 1 , wherein:
(a) the one or more contact lenses, corneal inserts, corneal implants, or intrastromal rings is/are adapted for moulding or holding corneal shape during and/or following treatment with the composition; and/or
(b) the one or more contact lenses, corneal inserts, corneal implants, or intrastromal rings acts/act as a carrier for the composition or as a composition eluting device.
3. The kit of claim 1 , wherein:
(a) the TGFβ3 polypeptide consists of the amino acid sequence of SEQ ID NO:1; and/or
(b) the dexamethasone is dexamethasone phosphate.
4. The kit of claim 1 , wherein the composition comprises one or more of:
(a) 10 to 100 ng/ml of the TGFβ3 polypeptide;
(b) 40 to 4000 ng/ml dexamethasone;
(c) a formulation for administration once daily or twice daily; or
(d) a co-formulation with one or more additional agents for the eye.
5. The kit of claim 4 , wherein the one or more additional agents for the eye are selected from the group consisting of: anaesthetic agents, anti-inflammatory agents, anti-microbial agents, and lubricants.
6. The kit of claim 1 , wherein:
(a) the kit includes one or more additional agents for the eye;
(b) the kit includes a contact lens solution; and/or
(c) the kit includes instructions for use.
7. The kit of claim 6 , wherein the one or more additional agents for the eye are selected from the group consisting of: anaesthetic agents, anti-inflammatory agents, anti-microbial agents, and lubricants.
8. A kit comprising:
(i) a first composition comprising a TGFβ3 polypeptide which comprises the amino acid sequence of SEQ ID NO:1 or which is at least 90% identical to the amino acid sequence of SEQ ID NO:1;
(ii) a second composition comprising dexamethasone or derivative thereof or a related steroidal agent; and
(iii) one or more contact lenses, corneal inserts, corneal implants, or intrastromal rings: wherein the kit is adapted to be used in:
(a) treating or preventing progression of a refractive error of an eye;
(b) treating or preventing progression of a condition associated with thinning or irregularity of a cornea; or
(c) treating or preventing progression of a corneal condition selected from the group consisting of: keratoconus, myopia, hyperopia, astigmatism, presbyopia, and stromal dystrophies;
and wherein use of the kit in any of (a), (b), or (c) does not result in scarring in the cornea or in the eye.
9. The kit of claim 8 , wherein:
(a) the one or more contact lenses, corneal inserts, corneal implants, or intrastromal rings is/are adapted for moulding or holding corneal shape during and/or following treatment with the first composition and the second composition; and/or
(b) the one or more contact lenses, corneal inserts, corneal implants, or intrastromal rings acts/act as a carrier for the first composition or the second composition, or acts/act as a composition eluting device.
10. The kit of claim 8 , wherein:
(a) the TGFβ3 polypeptide consists of the amino acid sequence of SEQ ID NO:1; and/or
(b) the dexamethasone is dexamethasone phosphate.
11. The kit of claim 8 , wherein the first composition comprises one or more of:
(a) 10 to 100 ng/ml of the TGFβ3 polypeptide;
(b) a formulation for administration once daily or twice daily; or
(c) a co-formulation with one or more additional agents for the eye.
12. The kit of claim 11 , wherein the one or more additional agents for the eye are selected from the group consisting of: anaesthetic agents, anti-inflammatory agents, anti-microbial agents, and lubricants.
13. The kit of claim 8 , wherein the second composition comprises one or more of:
(a) 40 to 4000 ng/ml dexamethasone;
(b) a formulation for administration once daily or twice daily; or
(c) a co-formulation with one or more additional agents for the eye.
14. The kit of claim 13 , wherein the one or more additional agents for the eye are selected from the group consisting of: anaesthetic agents, anti-inflammatory agents, anti-microbial agents, and lubricants.
15. The kit of claim 8 , wherein:
(a) the kit includes one or more additional agents for the eye;
(b) the kit includes a contact lens solution; and/or
(c) the kit includes instructions for use.
16. The kit of claim 15 , wherein the one or more additional agents for the eye are selected from the group consisting of: anaesthetic agents, anti-inflammatory agents, anti-microbial agents, and lubricants.
