Abstract | BACKGROUND: The phase 2a ALLEGRO trial (NCT02974868) investigated the safety and efficacy of ritlecitinib (PF-06651600) and brepocitinib (PF-06700841) in adults with alopecia areata. No randomized controlled trial for alopecia areata has evaluated correlations between clinician-assessed hair loss and patient-reported outcomes. OBJECTIVES: Report scores from the Alopecia Areata Symptom Impact Scale (AASIS; a patient-reported outcome tool) and explore the relationships of those scores with clinician-assessed Severity of Alopecia Tool ( SALT) scores at baseline and week 24 of the ALLEGRO trial. METHODS: Adults with alopecia areata were randomized to ritlecitinib (n = 48), brepocitinib (n = 47) or placebo (n = 47). After 24 weeks, the mixed-effects model with repeated measures was used to calculate the active treatment groups' AASIS score least-squares mean differences. Relationships between AASIS and SALT scores at baseline and week 24 were evaluated by Pearson's correlation coefficients using pooled data. RESULTS: Baseline AASIS and SALT scores were similar among treatment groups. Both active treatment groups reported significant improvements in AASIS scores at week 24 (least-squares mean differences vs. placebo for ritlecitinib, -0.8 to -2.3; brepocitinib, -0.9 to -3.7; P < 0.05 for all). At week 24, the mean SALT scores (standard deviation) improved compared with baseline [ritlecitinib, 54.4 (40.3) vs. 89.4 (15.8); brepocitinib, 31.9 (35.7) vs. 86.4 (18.1)]. The correlation coefficients between AASIS global and subscale scores and SALT scores at week 24 ranged from 0.34 to 0.58; P < 0.05 for all. CONCLUSIONS: Patients randomized to ritlecitinib or brepocitinib reported significantly improved AASIS and SALT scores at week 24 of the ALLEGRO trial compared to placebo. At week 24, medium-to-large correlations can be seen between AASIS global and subscale scores and SALT scores. Our experience with AASIS instrument highlighted several aspects that suggest new patient-reported outcome tools are needed to accurately assess patients' relevant alopecia areata related signs, symptoms and daily functioning.
