Activity Overview
This online, on-demand virtual symposium brings together renowned experts in atopic dermatitis. The OX40-OX40L interaction (2 co-stimulatory immune checkpoint molecules) plays a central role in the pathogenesis of atopic dermatitis. In this educational program, these experts review the evidence for the emerging role of OX40-OX40L axis inhibition in the treatment of patients with atopic dermatitis.
This educational activity is an archive of the live symposium held on June 7, 2025.
Target Audience
This educational activity is designed for dermatologists, allergists, immunologists, pediatricians, primary care physicians, nurse practitioners, physician assistants, and other health care professionals involved in the diagnosis, management, and treatment of patients with atopic dermatitis.
