Interim Analysis Shows Dupilumab Safe, Effective for AD Treatment at 2 Years


The findings are consistent with previously reported data.

Dupilumab was associated with improved disease control in patients with moderate-to-severe atopic dermatitis (AD) at two years, according to a new interim analysis.

The study, published in Dermatology and Therapy, examined two-year data from the PROSE AD Registry (an ongoing, prospective, observational, multicenter registry based in the U.S. and Canada that includes patients aged ≥ 12 years with moderate-to-severe AD). Dupilumab was administered according to local (country) guidelines. Researchers looked at a number of severity and patient-reported assessments, including body surface area affected by AD (BSA), Eczema Area and Severity Index (EASI), Dermatology Life Quality Index (DLQI), Pruritus Numerical Rating Scale (P-NRS), Patient-Oriented Eczema Measure (POEM), Patient Global Assessment of Disease (PGAD) questionnaire score, and adverse events (AEs). The study included 764 adult and adolescent patients, 632 (83%) of whom remained in the study at the time of the present interim analysis.

According to the results, improvements were reported at first post-baseline clinic visits, which occurred at approximately three months, and these improvements were sustained through the two-year analysis period. Patient-reported measures, such as reporting conditions as "very good/excellent" on the PGAD questionnaire in response to queries about overall quality of life with eczema, were also reported. Treatment with dupilumab was also safe and well-tolerated, which according to the authors was consistent with previously reported study results looking at dupilumab for the treatment of AD.

"Interim real-world data from the ongoing PROSE AD registry indicate that adolescent and adult patients with moderate-to-severe AD who initiated dupilumab experienced sustained improvement in disease control, symptom burden, and HRQoL; safety data were consistent with the known safety profile of dupilumab," the researchers wrote. "These results support previous findings from the dupilumab clinical trial program in AD, showing dupilumab has a risk/benefit profile suitable for the treatment of patients with moderate-to-severe AD."

The real-world design of the study (with its lack of a comparator or placebo group) was cited as a study limitation.
