Study Details

Study Description

Brief Summary

This is a global Phase 3 study to evaluate the safety and effectiveness of an investigational study drug (called PF-06651600) in adults and adolescents (12 years and older) who have alopecia areata. Eligible patients from the prior studies B7931005 (NCT02974868) and B7981015 (NCT03732807) will have an opportunity to enroll as well as patients who have not previously participated in either of these studies. The study is open-label and all patients entering the study will receive active study drug.

A sub-study of approximately 60 adult patients who are participating in the B7981032 study will be conducted at select sites in the US, Australia and Canada. The sub-study will evaluate the immune response to tetanus and meningococcal vaccines in patients who have received a minimum of 6 months of 50 mg PF-06651600.
