Adalimumab is a fully human monoclonal antibody that binds tumor necrosis factor, a key proinflammatory cytokine involved in the pathogenesis of psoriasis.


We sought to evaluate clinical efficacy and safety of adalimumab for moderate to severe psoriasis and investigate continuous versus interrupted therapy.


We conducted a 52-week, multicenter study of 1212 patients randomized to receive adalimumab (40 mg) or placebo every other week for the first 15 weeks. At least 75% improvement in the Psoriasis Area and Severity Index (PASI) score was the criterion for advancement through this multiphase study.


At week 16, 71% (578 of 814) of adalimumab- and 7% (26 of 398) of placebo-treated patients achieved greater than or equal to 75% improvement in the PASI score. During weeks 33 to 52, the percentage of patients rerandomized to placebo who lost adequate response (defined as <50% improvement in the PASI response relative to baseline and at least a 6-point increase in PASI score from week 33) was 28% compared with 5% of patients treated continuously with adalimumab.


Lack of an active comparator and evaluation of maintenance of response beyond week 52 are limitations.


Adalimumab is efficacious and well-tolerated in the treatment of chronic plaque psoriasis.


Clinical NCT00237887.
