AOD9604 is a GH fragment that comprises the last 16 amino acids of the larger growth hormone molecule. Although originally studied for fat loss, further studies have transitioned its application to regenerative medicine. In combination with hyaluronic acid (HA), it is now being used to help regenerate hyaline cartilage and is showing strong efficacy in the treatment of osteoarthritis. The combination acts to enhance the differentiation of adipose mesenchymal stem cells into bone, promote proteoglycan and collagen production in chondrocytes, and promote differentiation of myoblasts into C2C12 cells; all of which are essential for bone, cartilage, and muscle repair. These studies indicate that it has stronger therapeutic benefits compared to Bone Marrow Aspirate Concentrate (BMAC) and Platelet-Rich Plasma (PRP) therapy, which have also been emerging as candidates for osteoarthritis medications. AOD9604 + HA has proceeded to human WOMAC trials which allow the combination to be investigated for an osteoarthritis index that considers pain, stiffness, and functionality on a variety of scores.
