    Abstract:
    INTRODUCTION: Atopic dermatitis (AD) can require long-term therapy. Few real-world studies have evaluated long-term effectiveness from the patients' perspective. The aim of this study was to evaluate patient-reported outcomes (PROs) during long-term dupilumab treatment. METHODS: Adults with moderate-to-severe AD who initiated dupilumab through the US manufacturer patient support program and participated in RELIEVE-AD (a prospective patient survey study with a 12-month follow-up) were recontacted 30-36 months post-initiation regardless of current dupilumab use. The online questionnaire consisted of PROs, including the Atopic Dermatitis Control Tool (ADCT), use of concomitant AD therapies, satisfaction with current therapy, global change in itch relative to before dupilumab initiation, non-itch skin symptoms (skin pain/soreness, hot/burning feeling, and sensitivity to touch), flares, Dermatology Life Quality Index, sleep problems, and the AD-specific Work Productivity and Activity Impairment Questionnaire. RESULTS: Of 698 patients who initiated dupilumab (baseline) and were recontacted, 425 completed the 30-36-month survey. Significant reductions from baseline were reported in concomitant AD therapy use (P < 0.05); 54.4% reported not using other AD medications vs. 12.8% at baseline. At 30-36 months, all results (non-itch skin symptoms, flares, sleep problems, health-related quality of life work/activity impairment, disease control, and treatment satisfaction) were similar to or incrementally better than the 12-month timepoint, with significant improvements vs. baseline (P < 0.001). Global change in itch was reported as "very much better" by 75.3% of respondents. Adequate disease control (score < 7 on ADCT) was reported by 80.7% of respondents, and 86.8% were satisfied with the treatment. CONCLUSIONS: In clinical practice settings, patient-reported benefits of dupilumab were maintained in survey respondents during long-term treatment up to 36 months while the use of concomitant AD therapies reduced. Atopic dermatitis (also known as eczema) is a chronic skin disease that can have a profoundly negative effect on patients’ quality of life. To control disease symptoms, patients often need long-term treatment. Dupilumab is a treatment that has shown benefits in adults with moderate-to-severe atopic dermatitis (AD) when used in long-term (under 4 years) clinical trials; however, few studies have evaluated patients’ experiences of long-term dupilumab treatment outside of a clinical trial setting. This study was conducted to do so: 425 adults with moderate-to-severe AD who received dupilumab through a US manufacturer patient support program filled in an online questionnaire 30–36 months after starting treatment. The questionnaire included items on use of additional AD therapies, AD symptoms, quality of life, disease control, and satisfaction with treatment. Patients’ responses showed that, at 30–36 months after starting dupilumab treatment, 54% of patients reported not using any other medications for AD vs. 13% of patients when starting dupilumab treatment. In addition, since starting dupilumab, 75% of patients reported one of the most burdensome AD symptoms, itch, as being “very much better” vs. before starting treatment; 81% reported control of AD symptoms; 85% reported a meaningful improvement in quality of life; and 76% were “extremely” or “very” satisfied with the treatment. In summary, this study showed that long-term dupilumab treatment provides continued improvement in symptoms, treatment satisfaction, disease control, and quality of life in adults with moderate-to-severe AD while reducing the need for other AD treatments.
