Abstract
Introduction: Dupilumab is a monoclonal antibody approved in the United States (US) for patients aged ≥18 years with prurigo nodularis (PN). This analysis evaluated the real-world initial impact of dupilumab therapy on symptoms and treatment satisfaction among US adults with PN. Methods: RELIEVE-PN is an ongoing longitudinal prospective patient survey study assessing the real-world effectiveness of dupilumab in the treatment of adult patients with PN. Adults with PN were recruited through the US dupilumab patient support program and surveyed before (baseline) and 1 month after dupilumab initiation. PN symptoms over the last 7 days were assessed using the worst-itch numeric rating scale (WI-NRS), average-itch NRS, skin pain NRS, and skin burning or stinging/tingling NRS (range 0 [no symptom] to 10 [most severe symptom] for all). Treatment satisfaction with current therapy was evaluated using a 7-point Likert scale from “extremely satisfied” to “extremely dissatisfied”. Results: Of 84 patients (mean age, 57.5 years; 79.8% female; 83.3% White) completing the baseline survey and initiating dupilumab, 62 (mean age, 56.4 years; 77.4% female; 83.9% White) completed the Month 1 survey. At baseline, mean (SD) WI-NRS, average itch NRS, skin pain NRS, and skin burning/tingling NRS were 7.70 (2.24), 6.45 (2.25), 5.06 (2.87), and 5.51 (3.02), respectively. By month 1, mean (SD) WI-NRS, average itch NRS, skin pain NRS, and skin burning or stinging/tingling NRS improved to 5.56 (2.89), 4.35 (2.23), 3.40 (2.46), and 3.76 (2.60), respectively (p<0.001 for all). Additionally, significantly more patients reported they were satisfied with current PN treatment(s) at 1 month after dupilumab treatment initiation vs prior to starting dupilumab (77.4% vs 13.1%; p<0.001). Conclusion: Early results from the RELIEVE-PN study demonstrate improvement in symptoms and patient satisfaction with therapy as early as 1-month from treatment initiation of dupilumab. Further comparative research is needed to confirm these findings.
