    A 487-gene expression profile test identifies atopic dermatitis patients likely to respond to JAK inhibitors over Th2-targeted biologics.

  • 2

    The study developed a gene expression profile test using noninvasive skin scrapings to classify patients into two molecular subgroups.

  • 3

    Patients with a JAK inhibitor–responder profile showed better disease clearance and symptom control with JAK inhibitors than Th2 therapies.

  • 4

    The test employs a simple skin sampling method and standard RNA sequencing, positioning it as a potential companion diagnostic.

  • 5

    Molecular stratification may streamline care by aligning therapy selection with individual patient profiles, enhancing treatment outcomes.
