ORLANDO — A recent study showed that the administration of dupilumab was associated with comparable/significant improvement in signs and symptoms of atopic dermatitis in patients with or without comorbid asthma.
The research was presented at the 2018 joint congress of the American Academy of Allergy, Asthma & Immunology and the World Allergy Organization, held March 2-5, 2018, in Orlando, Florida.
The researchers further investigated if the presence of comorbid asthma influenced the improvement of signs and symptoms atopic dermatitis while participants were receiving the study drug.
Patients were randomly equally into 3 groups: subcutaneous dupilumab 300 mg every 2 weeks, subcutaneous dupilumab 300 mg weekly, or placebo. Duration of treatment for all groups was 16 weeks. The study measured Investigator's Global Assessment (IGA), Eczema Area and Severity Index (EASI), and peak pruritus Numerical Rating Scale (NRS).
Baseline characteristics were consistent in all groups and for all patients with or without asthma. After 16 weeks of treatment, patients with comorbid asthma receiving dupilumab 300 mg every 2 weeks achieved the best results compared with those receiving placebo. Patients without comorbid asthma showed similar results. All treatment groups had similar rates of adverse events, such as injection-site reactions and conjunctivitis.
Dupilumab inhibits key drivers of immune diseases. It is approved by the US Food and Drug Administration with or without concomitant administration of corticosteroids for treatment of adults with moderate to severe atopic dermatitis.
The researchers counsel that further studies are needed to assess the possible benefits of dupilumab treatment in patients with atopic dermatitis and symptomatic comorbid asthma.
