E.3 | Principal inclusion criteria |
• Men and non-pregnant non-breastfeeding women aged ≥ 18 years to ≤ 65 years at the time of the Screening visit. • SALT score ≥ 50 at Screening and Day 1 • Alopecia Areata Investigator Global Assessment ( AA-IGA) grade ≥ 3 at Screening and Day 1 • Duration of current episode of scalp hair loss (at Screening) must be at least 6 months, and not > 8 years, must affect ≥ 50% of the scalp, and scalp hair loss should be stable (ie, no significant spontaneous regrowth [> 10%] over the last 6 months).
Other protocol defined inclusion criteria apply

E.4 | Principal exclusion criteria |
• Participant with diffuse-type AA or other forms of hair loss, including traction alopecia, lichen planopilaris, central centrifugal cicatricial alopecia, frontal fibrosing alopecia, etc • Other active skin diseases affecting the scalp that in the opinion of the investigator may interfere with accurate assessment of SALT score • History of lack of response to ustekinumab, in the opinion of the investigator, (or any other therapeutic agent targeted to IL-12, IL-17, or IL-23) after at least 3 months of therapy • History of lack of response to a JAK inhibitor (eg, tofacitinib, ruxolitinib), in the opinion of the investigator • Thyroid medication or thyroid replacement therapies, if used, must be stable for 2 months and be maintained as such throughout the study • Any ongoing treatment known to affect hair growth including, but not limited to, topical steroids (applied to the scalp), intralesional steroids, systemic steroids, anthralin, squaric acid, diphenylcyclopropenone, tacrolimus, cyclosporine, finasteride/minoxidil (oral or topical) or other medication that cannot be discontinued at least 4 weeks prior to study intervention initiation (Day 1) and throughout the study.
