Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The study will investigate the efficacy and safety compared to placebo and the safety compared to ustekinumab of brodalumab in adolescents with moderate to severe plaque psoriasis. The study will also investigate if brodalumab affects development of vaccination-induced immune responses.

The study will run over 62-64 weeks (including screening, treatment, and safety follow-up) for each participant, but with the primary endpoint measured at Week 12.
