Abstract: Provided are liposomes that encapsulate adenosine. The liposomes may be formed from sphingomyelin or a combination of sphingomyelin and 1,2-dimyristoyl-sn-glycero-3-phosphocholine (DMPC) or a combination of sphingomyelin and 1,2-dimyristoyl-sn-glycero-3-phosphorylglycerol (DMPG) or a combination of sphingomyelin, DMPG, and DMPC. The liposomes encapsulating adenosine may be used to induce cartilage regeneration, treat osteoarthritis, alleviate joint pain, and/or slow, arrest, and/or reverse progressive structural tissue damage associated with osteoarthritis or treat osteoarthritis, rheumatoid arthritis, acute gouty arthritis, and/or synovitis. The liposomes may release adenosine for up to two weeks.

Abstract: The invention provides methods and compositions for treating or inhibiting the development of osteoarthritis in a subject having osteoarthritis or at risk for developing osteoarthritis and for stimulating or increasing cartilage production or formation in a subject. The methods feature administering to the subject a therapeutically effective amount of a composition comprising one or more agent from among adenosine, an adenosine receptor agonist, and an agent that upregulates or increases the amount of or the biological activity of adenosine, or an analog or derivative thereof. The adenosine receptor may be an A1, A2A, A2B and A3 adenosine receptor. The agent that upregulates or increases the amount of or the biological activity of adenosine may be dipyridamole or ticagrelor. The composition may be administered via intraarticular injection such as injection into the synovial fluid of a joint.
