About this trial
This is a prospective, randomized, double blind, placebo-controlled clinical trial. The study will take place at 4 sites. This trial will enroll a total of 68 patients with moderate to severe AA (affecting more than 50% of the scalp) at the time of screening with a targeted 54 subjects completers through Week 48. AA subjects must have evidence of hair regrowth within the last 7 years of their last episode of hair loss; and have screening IgE ≥ 200 and/or have personal and/or familial history of atopy.
Subjects will be randomized (2:1) to either receive weekly dupilumab or placebo for 48 weeks, with all subjects completing participation through Week 48 receiving an additional 48 weeks of dupilumab (through Week 96).

Trial outcomes
Primary outcomes
Change in the SALT score
Changes in the SALT score from baseline compared to week 48. SALT score is the sum of percentage of hair loss in all areas (higher score indicates greater hair loss). The change between baseline and Week 48 will be compared.
Secondary outcomes
Number of patients achieving an absolute SALT score of ≤ 20
Number of patients achieving an absolute SALT score of ≤ 20. SALT score is the sum of percentage of hair loss in all areas (higher score indicates greater hair loss). Total percentage of patients with absolute SALT score of ≤ 20 will be calculated.
Number of patients achieving improvement in Severity of Alopecia Tool (SALT) score
Number of patients achieving improvement in Severity of Alopecia Tool (SALT) score. SALT score is the sum of percentage of hair loss in all areas (higher score indicates greater hair loss). The proportion of patients achieving at least 30%/50%/75%/90% improvement will be calculated from weeks 16 to week 48.
Number of patients achieving improvement in Severity of Alopecia Tool (SALT) score
SALT score is the sum of percentage of hair loss in all areas (higher score indicates greater hair loss). The proportion of patients achieving at least 30%/50%/75%/90% improvement will be calculated from weeks 64 to week 96.
Change in the Alopecia Areata Symptom Impact Scale (AASIS)
Changes in the Alopecia Areata Symptom Impact Scale (AASIS) from baseline compared to Week 48. AASIS scale measures how the severe the subjects feel their alopecia areata symptoms have been in the past week (scale 0-10 where 0 indicates the symptom was not present and 10 indicates the symptom was as bad as you can imagine), where higher scores indicate worse symptoms.
