Phase 3 studies comparing brodalumab with ustekinumab in psoriasis

N Engl J Med 2015;373:1318–28. doi: 10.1056/NEJMoa1503824

Brodalumab treatment resulted in a rapid reduction in the signs and symptoms of PsO. The median time to a PASI 75 response with 210 mg of brodalumab Q2W was 4 weeks, approximately twice as fast as the median time to a response with ustekinumab.
