Treatment for degenerative joint disease using Hyaluronic Acid and Adelmidrol

Effect of an Intra-articular Treatment With a Combination of Hyaluronic Acid and Adelmidrol (Hyadrol®) on Pain, Joint Stiffness and Functional Limitation in Patients With Degenerative Joint Disease

Not applicable Interventional University of Roma La Sapienza · NCT06506656

This study is testing a new treatment combining Hyaluronic Acid and Adelmidrol to see if it can help people with arthritis in their hips and hands feel less pain and improve their joint function.

What this trial studies

This clinical investigation aims to evaluate the safety and efficacy of a treatment combining Hyaluronic Acid and Adelmidrol (Hyadrol®) for patients suffering from degenerative joint diseases, specifically arthritis of the hip and trapezium-metacarpal joints. The study focuses on addressing chronic neuroinflammation caused by mast cell overactivation and the reduction of viscoelastic properties in synovial fluid. Eligible participants will be those diagnosed with stage II-III coxarthrosis or rhizoarthrosis, experiencing significant pain. The treatment is designed to potentially restore joint function and alleviate pain.

Who should consider this trial

Good fit: Ideal candidates are individuals aged 40 and older with stage II-III coxarthrosis or rhizoarthrosis and a pain intensity of 5 or higher on the NRS.

Not a fit: Patients under 40 years old or those with inflammatory systemic diseases like rheumatoid arthritis may not benefit from this treatment.

Why it matters

Potential benefit: If successful, this treatment could significantly reduce pain and improve joint function for patients with degenerative joint disease.

How similar studies have performed: While the specific combination of Hyaluronic Acid and Adelmidrol is novel, similar approaches targeting neuroinflammation in joint diseases have shown promise in other studies.
