Title:	Medical use of matrix metalloproteinase inhibitors for inhibiting tissue contraction
Abstract:	The use of an MMP inhibitor, especially a collagenase inhibitor, in the manufacture of a medicament for the treatment of a natural or artificial tissue comprising extracellular matrix components to inhibit contraction of the tissue and methods for the treatment of tissue comprising extracellular matrix components to inhibit contraction.

Application Number:	08/716,155
Patent Claims:	1. A method for inhibiting or preventing contraction of healing tissue following trauma selected from the group consisting of surgical or accidental cut or tear, in which matrix metalloproteinase levels are not substantially elevated, or of cultured tissue, said tissue comprising an extracellular matrix component, said method comprising the step of administering an effective amount of a matrix metalloproteinase inhibitor to said tissue such that said contraction is inhibited or prevented. 2. The method of claim 1 wherein said tissue is tissue of the eye. 3. The method of claim 1 wherein said matrix metalloproteinase inhibitor is administered in a concentration of greater than 400 .mu.g/mL. 4. The method of claim 1 wherein said tissue is cultured tissue. 5. The method of claim 4 herein said tissue is skin graft tissue. 6. The method of claim 4 wherein said tissue is tissue of the eye. 7. The method of claim 4 wherein said matrix metalloproteinase inhibitor is administered at a concentration at least about 0.4 .mu.g/mL and less than 40 .mu.g/mL. 8. The method of claim 4 wherein said matrix metalloproteinase inhibitor is administered at a concentration more than about 400 .mu.g/m. 9. The method of claim 1 wherein said matrix metalloproteinase inhibitor is a collagenase inhibitor. 10. The method of claim 1 wherein said matrix metalloproteinase inhibitor is capable of inhibiting a matrix metalloproteinase selected from the group consisting of matrix metalloproteinases 1, 2 and 3. 11. The method of claim 1 wherein said matrix metalloproteinase inhibitor is N-[2(R)-2-(hydroxamido-carbonylmethyl)-4-methylpentanoyl]L-tryptophan methylamide. 12. The method of claim 1 wherein said matrix metalloproteinase inhibitor is a peptide hydroxamic acid or a pharmaceutically acceptable derivative thereof. 13. The method of claim 1 wherein said matrix metalloproteinase inhibitor is a monoclonal or polyclonal antibody to a matrix metalloproteinase. 14. The method of claim 1 wherein said matrix metalloproteinase inhibitor is a collagenase inhibitor administered in combination with at least one other matrix metalloproteinase inhibitor. 15. The method of claim 1 wherein said matrix metalloproteinase inhibitor is administered in combination with a further pharmacologically active ingredient selected from the group consisting of antibiotics, antifungals, steroids, enzyme inhibitors, epidermal growth factors, fibronectin and aprotinin. 16. The method of claim 1 wherein said matrix metalloproteinase inhibitor is administered in combination with an inhibitor of a collagen-stimulating cytokine. 17. A method of treating a human or other mammal to inhibit or prevent contraction of a post-trauma condition of a tissue selected from the group consisting of surgical or accidental cut or tear, in which matrix metalloproteinase is not substantially elevated, said tissue comprising an extracellular matrix component, said contraction being associated with healing of said tissue, comprising administering to said mammal an effective amount of a matrix metalloproteinase inhibitor to inhibit or prevent such contraction at a concentration greater than 400 .mu.g/mL. 18. The method of claim 17 wherein said contraction would occur as the result of surgical treatment of the eye. 19. The method of claim 17 wherein said contraction would occur as the result of glaucoma surgery.
