INTRODUCTION: ) and subsequent treatment success (SALT score ≤ 20) in four subgroups defined by baseline disease severity and AA episode duration to inform the treatment length required before assessing failure, based on disease presentation. METHODS: and subsequent SALT score ≤ 20 over time. RESULTS: achieved in 42%/25% of patients by Week 24, leading to SALT score ≤ 20 in 58%/43% at Week 52, respectively.
