A Narrative Review of the OX40-OX40L Pathway as a Potential Therapeutic Target in Atopic Dermatitis: Focus on Rocatinlimab and Amlitelimab

Atopic dermatitis (AD) is a common chronic inflammatory skin disease involving complex immune dysregulation, including the OX40-OX40L pathway. Rocatinlimab and amlitelimab, monoclonal antibodies targeting OX40 and OX40L, respectively, have shown promise in treating moderate-to-severe AD. Both therapies have demonstrated significant efficacy in reducing disease severity, with favorable safety profiles and no serious treatment-related adverse events. Both treatments outperformed placebo across key clinical endpoints, including skin clearance and symptom reduction, highlighting their potential as effective AD therapies. Although initial results are promising, further research is needed to evaluate the long-term effects, durability of response, and safety of these treatments. These findings support the therapeutic potential of targeting the OX40-OX40L pathway in AD, providing new options for patients with moderate-to-severe disease, with ongoing trials necessary to confirm their sustained benefits.
