Upadacitinib in Adolescents With Moderate to Severe Atopic Dermatitis
Clinical Summary
View sourceWhat was studied
Three ongoing double-blind, placebo-controlled phase 3 randomized trials (Measure Up 1, Measure Up 2, AD Up) assessed upadacitinib 15 mg or 30 mg once daily vs placebo in adolescents (12–17 years) with moderate to severe atopic dermatitis through week 76; at week 16, placebo recipients were rerandomized to upadacitinib. Coprimary outcomes were EASI-75, vIGA-AD 0/1 with ≥2-grade improvement, and ≥4-point WP-NRS improvement (for those with baseline WP-NRS ≥4).
Key findings
At week 76, EASI-75 was achieved by 89.1% and 96.1% (15 mg and 30 mg) in Measure Up 1; 84.4% and 93.6% in Measure Up 2; and 87.8% and 82.7% in AD Up. Herpetic infections occurred at 4.0, 1.9, and 1.1 events per 100 patient-years, and creatine kinase elevations at 11.6, 11.0, and 7.1 events per 100 patient-years across the three trials, with no new safety signals.
Study limitations
Placebo control ended at week 16 due to rerandomization, limiting long-term comparative inference. Adolescent results are pooled across three trials with different background therapy (monotherapy vs concomitant topical corticosteroids). The abstract does not provide numeric week-76 rates for vIGA-AD or WP-NRS outcomes.
Clinical implications
In adolescents with moderate to severe atopic dermatitis, upadacitinib 15–30 mg daily sustained high EASI-75 responses through 76 weeks, with safety consistent with prior experience and no new signals. Clinicians can consider long-term use while counseling about herpetic infections and creatine kinase elevations observed in these trials.
