Ustekinumab

Ustekinumab is an anti-IL12/23 IgG1 kappa human monoclonal antibody currently undergoing US Food and Drug Administration review for use as a psoriasis treatment. The candidate has also been evaluated in Phase 2 studies as a treatment for psoriatic arthritis, Crohn disease and multiple sclerosis. In large clinical trials, ustekinumab has proven effective for treating moderate to severe plaque psoriasis. Although long-term follow-up studies are needed to address safety concerns, the hopes are high for psoriasis treatment. Ustekinumab has recently been approved for marketing in Canada and Europe.
