Executive Summary
FDA Arthritis Advisory Committee decides Aug. 16 in a 6 to 2 vote that Amgen's rheumatoid arthritis agent Kineret (anakinra) demonstrated efficacy, but says efficacy is "modest" in comparison to methotrexate. An interim analysis of 506 patients found a higher response rate for combo therapy with anakinra plus methotrexate vs. methotrexate alone. Based on results from an open-label study showing a higher rate of infection in patients receiving anakinra plus Immunex' Enbrel (etanercept), the committee recommended that anakinra labeling should have a strong warning against use with TNF-inhibitors, pending results of a double-blind safety trial with etanercept
