Background
Management of moderate-to-severe atopic dermatitis (AD) commonly requires long-term treatment.
Objective
The aim of this study was to report the safety and efficacy of dupilumab treatment for up to 3 years in adults with moderate-to-severe AD.
Methods
This ongoing, multicenter, open-label extension study (LIBERTY AD OLE; NCT01949311) assessed dupilumab treatment in adults previously enrolled in dupilumab trials. Patients received dupilumab 300 mg weekly up to 148 weeks. The primary outcome was safety.
Results
Of 2677 patients enrolled and treated, 347 reached week 148. Mean self-reported drug compliance was 98.2%. Safety data were consistent with previously reported trials (270.1 adverse events [AEs]/100 patient-years; 6.9 serious AEs/100 patient-years) and the known dupilumab safety profile. Common AEs (≥ 5% of patients) included nasopharyngitis, AD, upper respiratory tract infection, conjunctivitis, headache, oral herpes, and injection-site reactions. AD signs and symptoms showed sustained improvements during treatment with mean (standard deviation, mean percentage change from parent study baseline) Eczema Area and Severity Index 1.4 (3.2, − 95.4%) and weekly Pruritus Numerical Rating Scale 2.2 (1.8, − 65.4%) at week 148.
Limitations
No control arm; fewer patients at later time points; regimen different from the approved 300 mg every 2 weeks dose.
Conclusion
These safety and efficacy results support dupilumab as a continuous long-term treatment for adults with moderate-to-severe AD.
Trial Registration
ClinicalTrials.gov: NCT01949311.
