The main purpose of this study is to determine the efficacy and safety of baricitinib for the treatment of severe or very severe alopecia areata (hair loss) in children from 6 years to less than 18 years of age.

The study is divided into 4 periods, a 5-week Screening period, a 36-week Double-Blind Treatment Period, an approximately 2-year Long-term Extension Period, and a 4-week Post-treatment Follow-up period.

You CAN'T join if...

  • Primarily "diffuse" type of AA (characterized by diffuse hair shedding).
  • Are currently experiencing other forms of alopecia including, but not limited to trichotillomania, telogen effluvium, chemotherapy-induced hair loss, or any other concomitant conditions (for example, tinea capitis, psoriasis, lupus erythematosus, or secondary syphilis) that would interfere with evaluations of the effect of study medication on AA.
  • Are largely or wholly incapacitated permitting little or no self-care, such as being bedridden
  • Have uncontrolled arterial hypertension
  • Have had major surgery within 8 weeks prior to screening or will require major surgery during the study
  • Have a history or presence of cardiovascular, respiratory, hepatic, gastrointestinal, endocrine, hematological, neurological, or neuropsychiatric disorders or any other serious and/or unstable illness that, in the opinion of the investigator, could constitute an unacceptable risk when taking IP or interfere with the interpretation of data.
  • Have a positive test for hepatitis B virus (HBV) infection
  • Have hepatitis C virus (HCV) infection (positive for anti hepatitis C antibody with confirmed presence of HCV ribonucleic acid [RNA]).
  • Have evidence of human immunodeficiency virus (HIV) infection and/or positive HIV antibodies.
