Composition and method for treating connective tissue damage
View Patent ↗The present invention provides a composition, and a method of use thereof, for treating connective tissue damage in man and in animals, which comprises a therapeutically effective amount of chondroitin sulfate, N-acetyl D-glucosamine, and hyaluronan (hyaluronic acid). Particularly, the present invention provides a composition, and a method of use thereof, for treating connective tissue damage including, but not limited to, arthritic disease, osteoarthritis, rheumatoid arthritis, osterochondrosis dessicans, cartilage damage, joint injury, joint inflammation, joint synovitis, degenerative joint disease (DJD), post surgical DJD, traumatic injury, fracture, tendon damage, ligament damage, skeletal damage, musculoskeletal damage, fiber damage, adipose tissue damage, blood cell damage, and plasma damage. Compositions for delivery of the present invention include those for parenteral, oral, and transmucosal delivery and for direct surgical placement onto the affected tissues.
1. A method for treating connective tissue damage in a mammal comprising parenterally administering to a mammal in need thereof, a therapeutically effective amount of a composition comprising therapeutic amounts of chondroitin sulfate, N-acetyl D-glucosamine, and hyaluronan, wherein said connective tissue is selected from the group consisting of tendon, ligament, and bone.
2. The method of claim 1 , wherein the therapeutically effective amount of chondroitin sulfate comprises from between about 0.5 grams to about 1.5 grams of a suitable chondroitin sulfate per unit dose of the composition.
3. The method of claim 2 , wherein the suitable chondroitin sulfate is chondroitin 4-sulfate, chondroitin 6-sulfate, or a mixture thereof.
4. The method of claim 1 , wherein the therapeutically effective amount of N-acetyl D-glucosamine is from about 0.5 grams to about 1.5 grams of N-acetyl D-glucosamine per unit dose of the composition.
5. The method of claim 1 , wherein the therapeutically effective amount of hyaluronan is from about 10 mg to about 50 mg of hyaluronan per unit dose of said composition.
6. The method of claim 1 , wherein the composition is a sterile solution for parenteral administration or dispersed onto or within a deformable semi-solid or solid material adapted for implantation onto or between tissues of a human or animal body.
7. The method of claim 6 , wherein said material is dissolvable or biodegradable and in the form of a mesh, gauze, bandage, a surgical suture, or staple material suitable for a surgical process or device.
8. The method of claim 1 , wherein the composition is administered in combination with one or more therapeutic agents.
9. The method of claim 8 , wherein the therapeutic agent is selected from the group consisting of a synthetic or a non-synthetic corticosteroid agent, nonsteroidal anti-inflammatory agent, antirheumatic agent, immunoregulatory agent, immunosuppressant agent, articular function augmentory agent, and interleukin production inhibitor.
10. The method of claim 9 , wherein said therapeutic agent is a corticosteroid agent.
11. The method of claim 9 , wherein said therapeutic agent is a growth factor.
12. The method of claim 9 , wherein said therapeutic agent is a tissue or a stem cell having a therapeutic effect.
13. A method for treating connective tissue damage in a mammal comprising parenterally administering to a mammal in need thereof, a therapeutically effective amount of a composition consisting essentially of therapeutic amounts of chondroitin sulfate, N-acetyl D-glucosamine, and hyaluronan, wherein said connective tissue is selected from the group consisting of tendon, ligament, and bone.
14. The method of claim 13 , wherein the therapeutically effective amount of chondroitin sulfate comprises from between about 0.5 grams to about 1.5 grams of a suitable chondroitin sulfate per unit dose of the composition, and wherein the chondroitin sulfate is chondroitin 4-sulfate, chondroitin 6-sulfate, or a mixture thereof.
15. The method of claim 13 , wherein the therapeutically effective amount of N-acetyl D-glucosamine is from about 0.5 grams to about 1.5 grams of N-acetyl D-glucosamine per unit dose of the composition.
16. The method of claim 13 , wherein the therapeutically effective amount of hyaluronan is from about 10 mg to about 50 mg of hyaluronan per unit dose of said composition.
17. The method of claim 13 , wherein the composition is a sterile solution for parenteral administration or dispersed onto or within a deformable semi-solid or solid material adapted for implantation onto or between tissues of a human or animal body.
18. The method of claim 17 , wherein said material is dissolvable or biodegradable and in the form of a mesh, gauze, bandage, a surgical suture, or staple material suitable for a surgical process or device.
19. The method of claim 13 , wherein the composition is administered in combination with one or more therapeutic agents.
20. The method of claim 19 , wherein the therapeutic agent is selected from the group consisting of a synthetic or a non-synthetic corticosteroid agent, nonsteroidal anti-inflammatory agent, antirheumatic agent, immunoregulatory agent, immunosuppressant agent, articular function augmentory agent, and interleukin production inhibitor.
