Study of Dupilumab to Demonstrate Efficacy in Subjects With Nummular Eczema

Nummular eczema (NE) is an idiopathic chronic inflammatory skin disease that occurs throughout all life periods. Diagnosis is made primarily clinically in correlation with histological findings. Treatment of NE is difficult. Standard treatment consists of the use of emollients, topical as well as systemic corticosteroids and phototherapy. Nevertheless, remission is hard to achieve and relapse occurs often. Patients usually suffer from severe pruritus and reduced quality of life. Therefore, new therapeutic strategies are urgently needed. Dupilumab (Dupixent®), a monoclonal antibody inhibiting the IL-4 and IL-13 pathway by targeting the IL-4-receptor, has been approved for the treatment of moderate-to-severe atopic dermatitis (AD). Since there is an overlap between AD and NE with both being caused by impaired epidermal barrier, broad immune-mediated inflammation and microbial skin colonization, using Dupilumab in NE seems to be promising.
