Humira 40 mg hver anden uge blev undersøgt i to randomiserede, 24 ugers dobbelt- blinde placebo - kontrollerede forsøg med 393 patienter med aktiv ankyloserende spondylitis (gennemsnits score ved baseline for sygdomsaktivitet [Bath Ankylosing Spondylitis Disease Activity Index (BASDAI)] var 6, 3 i alle grupper), som ikke havde responderet tilstrækkeligt på konventionel behandling.
