: Definitive diagnosis of AA of more than 6 months.
Diagnosis of severe AA, as determined by all of the following.
Hair loss affecting ≥50% of the scalp, as measured by Severity of Alopecia Tool (SALT) at both screening and baseline visits.
Current episode of hair loss of less than 8 years.
No evidence of terminal hair regrowth within 6 months, equivalent to less than 10 points spontaneous reduction in SALT over the past 6 months.
Participants with severe AA for ≥8 years may be enrolled if episodes of regrowth are observed in the affected areas over the past 8 years, spontaneously and/or under treatment.
Willingness in maintaining a consistent hair style and hair care, including hair products, and to refrain from weaves, extensions, adhesive wigs, other than banded perimeter devices, refrain from shaving of scalp hair for 2 weeks prior to each study visit from baseline to the end of study.

: Participants that are currently experiencing other forms of alopecia, including but not limited to: androgenetic alopecia, trichotillomania, telogen effluvium, traction alopecia, scarring alopecia.
Participants currently with any local or systemic active medical conditions, including but not limited to seborrheic dermatitis requiring topical treatment to the scalp, lupus erythematosus, lichen planus, psoriasis, secondary syphilis, tinea capitis, thyroiditis, systemic sclerosis, hair transplants, micropigmentation/tattoo of the scalp that in opinion of the Investigator would interfere with evaluations of the investigational medicinal product effect on AA due to scalp inflammation.
Received the specified treatment regimens within the timeframe outlined in the protocol.
Prior use of any oral JAKi or the topical JAKi ruxolitinib for more than 12 months, regardless if washout period is respected.
Participants with shaved heads must not enter the study until hair has grown back and SALT score can be reliably administered.
