The United States Food and Drug Administration (FDA) has accepted the filing of a Pre-Market Approval (PMA) Supplement to expand the indication of Hyalgan® (sodium hyaluronate) to include treatment of shoulder pain due to osteoarthritis or osteoarthritis in association with rotator cuff tears and/or adhesive capsulitis in patients who have failed to respond adequately to conservative nonpharmacologic therapy, and to simple analgesics, e.g., acetaminophen. Hyalgan® is currently indicated for the treatment of pain in osteoarthritis of the knee in patients who have failed to respond adequately to conservative nonpharmacologic therapy, and to simple analgesics, e.g., acetaminophen. Sanofi-aventis is the sole distributor in the United States of Hyalgan, which is lincensed and manufactured by Fidia Farmaceutici of Italy.
In the US clinical trial of 495 patients, the only adverse event showing statistical significance vs. placebo was injection-site pain.
Other adverse events included gastrointestinal complaints, headache, local ecchymosis and rash, local joint pain and swelling, and local pruritus. However, the incidence of these events was similar in the HYALGAN and placebo groups.
In other clinical studies, the frequency and severity of adverse events occurring during repeat treatment cycles did not increase over that reported for a single treatment cycle.
