Study Description

Brief Summary

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.

Detailed Description

This study aims on investigating the efficacy of Dupilumab in NE patients. The primary endpoint is the percent change in Eczema Area and Severity Index (EASI) score from baseline to week 16.

Secondary endpoints include the number of patients achieving an improvement (decrease) in Physician Global Assessment (PGA) by two or more points at week 16 as compared to week 0 or achieving an absolute PGA of 0 or 1 at Week 16, the EASI 50 score at week 16, the change from baseline in transepidermal waterloss (TEWL) at week 16, significant histological improvement at week 16, change from baseline in the reduction of the use of topical steroids at week 16, change form baseline in the Dermatology Life Quality Index (DLQI) at week 16, change from baseline in Pruritus Visual Analog Scale (VAS), change from baseline in the global satisfaction subscale of the treatment satisfaction questionnaire for medication (TSQM) score at week 16 and the safety of Dupilumab.

Arms and Interventions

Arm	Intervention/Treatment
Experimental: Dupilumab Patients randomized to this arm will receive two subcutaneous injections of Dupilumab 300 mg (for a total of 600 mg) as a loading dose on Day 1, followed by single 300 mg injection of Dupilumab every 2 weeks (q2w) from week 2 to week 16.	Drug: Experimental: Dupilumab 300 MG/2 ML Subcutaneous Solution [DUPIXENT] Subcutaneous
Placebo Comparator: Placebo Patients randomized to this arm will receive identically matching doses of placebo. Two subcutaneous injections of placebo as a loading dose (to mimic the experimental Dupilumab arm) on Day 1 followed by a single injection q2w from Week 2 to Week 16.
