Summary

To date, there are no effective therapy for the management of Netherton Syndrome (NS) Patients use emollients with a limited efficacy on scaling and no efficacy on skin inflammation and pruritus. They may also use topical corticosteroids or calcineurin inhibitors in case of eczematous lesions. The use of therapies targeting skin inflammation has been reported in a few case reports. Their efficacy is very limited and their uses are limited because of the chronicity of the disease, the impaired skin barrier function and the risk for skin infections and skin cancers. Therefore, there is a huge medical need for novel therapies in NS.The expected consequences of this study are that a 16-week course of dupilumab will be more effective than placebo for the treatment of moderate to severe NS Dupilumab could therefore improve skin condition and quality of life.

Detailed description

This is a proof of concept (pilot) double-blind randomized placebo-controlled study evaluating the efficacy and safety of dupilumab for the treatment of NS. Patients will be randomized in a 2:1 ratio to receive dupilumab (2 doses of 300 mg), or placebo, at baseline and then 1 dose of dupilumab 300 mg, or placebo, every 2 weeks until week 14 (total of 8 administrations).Moderate to severe NS were selected in order to be able to measure the improvement of skin condition.
