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.

Primary Outcome Measures :
  1. Number of subjects reporting treatment-emergent adverse events [ Time Frame: Baseline through 2 years (24 months) ]
  2. Number of subjects reporting serious adverse events and adverse events [ Time Frame: Baseline through 2 years (24 months) ]
  3. Number of subjects with clinically significant abnormalities in vital signs [ Time Frame: Baseline through 2 years (24 months) ]
  4. Number of subjects with clinically significant abnormalities in clinical laboratory values [ Time Frame: Baseline through 2 years (24 months) ]

Secondary Outcome Measures :
  1. Percentage of subjects achieving an absolute Severity of Alopecia Tool (SALT) Score <=10 [ Time Frame: Months 1, 3, 6, 9, 12, 15, 18, 21, and 24 ]
    SALT is a quantitative assessment of scalp hair loss with scores ranging from 0 (no scalp hair loss) to 100 (complete scalp hair loss).

  2. Percentage of subjects achieving a 50% improvement in SALT score from baseline [ Time Frame: Months 1, 3, 6, 9, 12, 15, 18, 21, and 24 ]
    SALT is a quantitative assessment of scalp hair loss with scores ranging from 0 (no scalp hair loss) to 100 (complete scalp hair loss).

  3. Percentage of subjects achieving a 75% improvement in SALT score from baseline [ Time Frame: Months 1, 3, 6, 9, 12, 15, 18, 21, and 24 ]
    SALT is a quantitative assessment of scalp hair loss with scores ranging from 0 (no scalp hair loss) to 100 (complete scalp hair loss).

  4. Percentage of subjects achieving a 90% improvement in SALT score from baseline [ Time Frame: Months 1, 3, 6, 9, 12, 15, 18, 21, and 24 ]
    SALT is a quantitative assessment of scalp hair loss with scores ranging from 0 (no scalp hair loss) to 100 (complete scalp hair loss).

  5. Absolute SALT scores [ Time Frame: Months 1, 3, 6, 9, 12, 15, 18, 21, and 24 ]
    SALT is a quantitative assessment of scalp hair loss with scores ranging from 0 (no scalp hair loss) to 100 (complete scalp hair loss).

  6. Percentage of subjects achieving at least a 2 grade improvement or a score of 3 in Eyebrow Assessment (EBA) score [ Time Frame: Months 1, 3, 6, 12, 18, and 24 ]
    EBA is a numeric rating scale developed to characterize eyebrow hair loss. The numeric rating scale ranges from 0 (none) to 3 (normal).

  7. Percentage of subjects achieving at least a 2 grade improvement or a score of 3 in Eyelash Assessment (ELA) score [ Time Frame: Months 1, 3, 6, 12, 18, and 24 ]
    ELA is a numeric rating scale developed to characterize eyelash hair loss. The numeric rating scale ranges from 0 (none) to 3 (normal).

  8. Change from baseline in Alopecia Areata Patient Priority Outcomes (AAPPO) scale scores [ Time Frame: Months 1, 3, 6, 9, 12, 18, and 24 ]
    The AAPPO scale is a self administered questionnaire that measures the symptoms of AA as well as psychological and functional impacts over the past week.

  9. Change from baseline in the depression scale of the Hospital Anxiety and Depression Scale (HADS) [ Time Frame: Months 1, 3, 6, 9, 12, 15, 18, 21, and 24 ]
    HADS is a participant rated questionnaire with 2 subscales. HADS-A assesses state of generalized anxiety; HADS-D assesses state of lost interest and diminished pleasure response. Each subscale comprised of 7 items with range 0 (no presence of anxiety or depression) to 3 (severe feeling of anxiety or depression). Total score 0 to 21 for each subscale; higher score indicates greater severity of anxiety and depression symptoms.

  10. Change from baseline in the anxiety scale of the Hospital Anxiety and Depression Scale (HADS) [ Time Frame: Months 1, 3, 6, 9, 12, 18, and 24 ]
    HADS is a participant rated questionnaire with 2 subscales. HADS-A assesses state of generalized anxiety; HADS-D assesses state of lost interest and diminished pleasure response. Each subscale comprised of 7 items with range 0 (no presence of anxiety or depression) to 3 (severe feeling of anxiety or depression). Total score 0 to 21 for each subscale; higher score indicates greater severity of anxiety and depression symptoms.

  11. Change from baseline in 36 Item Short Form Health Survey version 2 Acute (SF36v2 Acute) [ Time Frame: Months 1, 3, 6, 12, 18, and 24 ]
    SF-36 is a standardized survey evaluating 8 aspects of functional health and well being. These 8 aspects can also be summarized as physical and mental component scores (CS).
