CME Satellite Symposium: Illuminate the Role of IL-13 Inhibitors for the Management of Atopic Dermatitis

Alexandra Golant, MD, Mona Shahriari, MD, and G. Michael Lewitt, MD, presented a session focused on the evolving role of interleukin-13 (IL-13) inhibition in atopic dermatitis, sharing new insights, case experiences, and strategies for optimizing treatment in clinical practice.

Dr Golant opened by underscoring the central role of IL-13 in atopic dermatitis pathophysiology. Elevated across age groups and skin tones in patients with atopic dermatitis, IL-13 drives barrier disruption, decreases filaggrin expression, and fuels pruritus and lichenification. She reviewed case examples, including an adolescent with long-standing disease who achieved rapid and sustained improvement on lebrikizumab. Dr Golant emphasized how patient-defined goals such as comfort at school, confidence in social settings, and reduced topical burden align with the responses seen in trials. Early and aggressive targeting of IL-13 was presented as a way to meet both clinical and quality-of-life outcomes.

Dr Shahriari expanded on the comparative efficacy of IL-13 biologics, highlighting pivotal data from SOLO, ADvocate, ECZTRA, and long-term extension studies. Both lebrikizumab and tralokinumab demonstrated durable control, with maintenance of EASI90 and pruritus relief extending beyond 2 years. She also addressed switching strategies, noting that patients discontinuing dupilumab for adverse events often achieved better outcomes on lebrikizumab compared with those stopping for inadequate response. Dr Shahriari presented cases of patients with dupilumab-associated ocular surface disease whose symptoms resolved when transitioned to tralokinumab or Janus kinase inhibitors, underscoring the importance of individualized sequencing.

Dr Lewitt concluded with a practical perspective on integrating IL-13 inhibitors into daily practice. He illustrated this with a young adult patient who prioritized clearance of hand and facial dermatitis with minimal treatment burden. After 16 weeks of lebrikizumab, both skin clearance and pruritus improved markedly, restoring confidence and function. Dr Lewitt highlighted safety profiles across the IL-13 inhibitor class, emphasizing that adverse events are generally manageable and that selective inhibition may be particularly appealing when patients prefer targeted therapy without systemic immunosuppression. Looking forward, the faculty noted that biologics with extended half-lives, bispecific antibodies, and oral agents may further expand long-term disease control options.
