Summary for Patent: 6,379,667
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.

Assignee: University of Florida Research Foundation (Gainesville, FL) Moorfields Eye Hospital National Health Service Trust (London, GB)
Application Number:09/368,307
Patent Claims:1. A method for treating healing tissue following thermal burn to inhibit or prevent scarring associated with contraction of such tissue, said tissue comprising an extracellular matrix component, said contraction being associated with untreated healing of said tissue, said method comprising administration, to a patient in need of such treatment, of a therapeutically effective regimen of a metalloproteinase inhibitor to said tissue such that said contraction is inhibited or prevented.

2. The method of claim 1 wherein said matrix metalloproteinase inhibitor is administered in a concentration of greater than 400 .mu.g/mL.

3. The method of claim 1 wherein said matrix metalloproteinase inhibitor is a collagenase inhibitor.

4. 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.

5. The method of claim 1 wherein said matrix metalloproteinase inhibitor is N-[2(R)-2-(hydroxamido-carbonylmethyl)-4-methylpentanoyl]L-tryptophan methylamide.

6. The method of claim 1 wherein said matrix metalloproteinase inhibitor is a peptide hydroxamic acid or a pharmaceutically acceptable derivative thereof.

7. The method of claim 1 wherein said matrix metalloproteinase inhibitor is a monoclonal or polyclonal antibody to a matrix metalloproteinase.

8. 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.

9. 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.

10. The method of claim 1 wherein said matrix metalloproteinase inhibitor is administered in combination with an inhibitor of a collagen-stimulating cytokine.

11. The method of claim 1 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.

12. A method of treating a human or other mammal to inhibit or prevent contraction of a post-thermal-burn tissue, said tissue comprising an extracellular matrix component, said contraction being associated with untreated 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.

13. A method for inhibiting or preventing contraction of healing tissue following thermal burn, in which matrix metalloproteinase levels are not substantially chronically elevated, said tissue comprising an extracellular matrix component, said contraction being associated with untreated healing of said tissue, said method comprising the step of administering to said tissue over at least the period during which contraction occurs, an effective amount of a matrix metalloproteinase inhibitor such that said contraction is inhibited or prevented.

14. A method of inhibiting or preventing contraction of fibroblasts of healing tissue following thermal burn, said tissue comprising an extracellular matrix component, said contraction being associated with untreated healing of said tissue, said method comprising the step of administering during a time during wound healing when contraction occurs, an effective amount of a matrix metalloproteinase inhibitor to said tissue such that said contraction is inhibited or prevented.
