Abstract

Methods and compositions are disclosed for an intra-articular injection for the treatment of osteoarthritis. The methods and compositions comprising combinations of hyaluronic acid and a bone morphogenetic protein, like rhGDF-5, can be useful for any synovial joint, including the knee, shoulder, hip, ankle, hands, spinal facet, or temporomandibular joint, both for the relief of pain and for slowing disease progression.

Claims

1. A method for treating a joint condition, comprising:

combining a solution of hyaluronic acid (HA) with a bone morphogenetic protein (BMP) to form a mixture in which the BMP is precipitated and dispersed at a concentration in the range of about 5 μ

g/ml to 90 μ

g/ml in the solution of HA, the mixture having a pH in the range of about 3 to 8; and

injecting the mixture into a subject to treat the joint condition, the BMP being capable of becoming solubilized and biologically active within the subject after injection.

2. The method of claim 1, wherein the BMP is a growth and differentiation (GDF) protein.

3. The method of claim 1, wherein the BMP is in a liquid state prior to combining with the solution of HA.

4. The method of claim 1, wherein the BMP is in a lyophilized state prior to combining with the solution of HA.

5. The method of claim 1, wherein the mixture has a pH in the range of about 4 to 7.5.

6. The method of claim 1, wherein the HA has a molecular weight of at least about 500 kDa.

7. The method of claim 1, wherein the HA is at a concentration in the range of About 5 mg/ml to 60 mg/ml.
