Dupilumab treatment improves quality of life in adult patients with moderate-to-severe atopic dermatitis: results from a randomized, placebo-controlled clinical trial

Atopic dermatitis is a skin disease, commonly known as eczema. It affects up to 1 in 10 adults. Atopic dermatitis is usually very itchy, causing people to wake up at night, and feel “low”. This state of general discomfort is known as reduced quality of life. Dupilumab is a new treatment approved in the U.S.A. for adults with moderate‐to‐severe atopic dermatitis. The treatment blocks some of the mechanisms involved in the disease. In a clinical trial conducted in Europe, researchers observed 109 patients with moderate‐to‐severe atopic dermatitis. The patients received dupilumab over 12 weeks. They found that the treatment improved the eczema and its symptoms, such as itch. The researchers also studied how the treatment affected quality of life in 64 out of 109 patients in the study. These patients had answered a set of questions that measures how atopic dermatitis affects their quality of life (Quality of Life Index for atopic dermatitis [QoLIAD]). Thirty‐two patients received dupilumab 300 mg weekly, by injection under the skin, and 32 received placebo. About 6 out of 10 patients treated with dupilumab had better quality of life over the 12 weeks, whereas only about 1 in 10 placebo‐treated patients improved. The researchers also found a relatively strong link between improvements with dupilumab in QoLIAD score and improvements in the eczema and symptoms. Dupilumab was well‐tolerated by the patients. The authors conclude that dupilumab, a new breakthrough treatment for atopic dermatitis, improves eczema and its symptoms, and in turn, the patients’ quality of life.
