Baricitinib pediatric indications — approvals and clinical development for juvenile idiopathic arthritis, pediatric atopic dermatitis, and pediatric alopecia areata — represent the systematic expansion of baricitinib's indication portfolio into younger patient populations, with the Baricitinib Market reflecting pediatric approval as a market expansion strategy alongside adult indication development.

Pediatric AD approval extension — baricitinib receiving EMA and FDA approval for atopic dermatitis in children as young as two years — dramatically expands the potential AD patient population beyond adults where significant pediatric AD unmet need exists. Children with moderate-to-severe AD who fail topical therapy represent a population where systemic treatment options have historically been limited to cyclosporine (off-label) or dupilumab in patients above appropriate age thresholds.

JIA baricitinib clinical program — the ongoing Lilly clinical trial program for juvenile idiopathic arthritis including polyarticular JIA following the pediatric investigation plan approved by EMA — represents the systematic regulatory strategy for extending baricitinib's rheumatology indication into pediatric inflammatory arthritis. Successful JIA approval would further diversify baricitinib's pediatric indication portfolio with clinical positioning similar to its adult RA success.

Pediatric alopecia areata baricitinib data — clinical experience and ongoing studies in pediatric patients with severe AA extending alopecia areata treatment from the adult FDA approval — represent the natural pediatric extension of the adult indication given AA's significant pediatric prevalence and psychological impact in school-age children. Pediatric AA clinical program development supports both regulatory expansion and clinical need given the profound psychosocial impact of severe hair loss in children and adolescents.

Do you think pediatric baricitinib indications will contribute meaningfully to commercial revenue, or will the smaller pediatric market size and more conservative prescribing approach in children limit commercial significance relative to adult indications?
