• Subject has a history of at least 6 months of moderate to severe AA (≥ 50% scalp involvement) as measured using the SALT score; OR subject has ≥ 95% loss of scalp hair for enrollment as AA totalis (AT) or universalis (AU) subtypes.
• Subject has a screening IgE > 200 and/or personal and/or familial history of atopy.

• Subjects must meet the following laboratory criteria:
