A Review of the Long-Term Safety and Efficacy of Upadacitinib in the Treatment of Atopic Dermatitis.

Atopic dermatitis (AD) is a common inflammatory skin condition characterized by erythema and intense pruritus. A key pathway implicated in its pathogenesis is the Janus kinase (JAK)/signal transducer and activator of transcription (STAT) signaling pathway. Upadacitinib, a JAK inhibitor, has been approved for the treatment of moderate-to-severe AD. This review evaluates the long-term safety and efficacy of upadacitinib in AD, incorporating findings from the Measure Up 1 and Measure Up 2 phase 3 studies.
