Description of intervention(s) / exposure
Treatment: Drugs - PF-06651600
Other interventions - Tetanus and diphtheria toxoids and acellular pertussis (Tdap) vaccine
Other interventions - Meningococcal (groups A, C, W-135 and Y [ACWY]) oligosaccharide diphtheria CRM197 conjugate vaccine

Experimental: Treatment sequence 1 - Participants who did not previously receive study intervention in either study B7931005 or B7981015 will receive 200 milligrams (mg) PF-06651600, given as four 50 mg tablets once daily (QD) for 1 month, followed by 50 mg PF-06651600 tablet or capsule given QD for 59 months.
Patients participating in the vaccine sub-study will receive the 2 vaccines or one of the 2 vaccines at the vaccine sub-study Day 1, which will occur at a scheduled study visit on or after the Month 9 visit and prior to or on the Month 56 visit of the main B7981032 study.

Experimental: Treatment sequence 2 - Participants who previously received study intervention in either study B7931005 or B7981015 will receive 50 mg PF-06651600 tablet or capsule given QD for 59 months.
Patients participating in the vaccine sub-study will receive the 2 vaccines or 1 of the 2 vaccines at the vaccine sub-study Day 1, which will occur at a scheduled study visit on or after the Month 6 visit and prior to or on the Month 56 visit of the main B7981032 study.

Summary
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.
