Anakinra is indicated for use alone or in combination with DMARDs other than anti–tumor necrosis factor (TNF) therapies.
Safety and effectiveness of were evaluated in three randomized, placebo-controlled trials of 1392 patients at least 18 years of age with active RA. A fourth study assessed the drug's safety in 1414 similar patients who were DMARD free or received concurrent medications, including some DMARDs.
