Study Summary

Primary Objective: To demonstrate the efficacy of dupilumab on itch response in participants with prurigo nodularis (PN), inadequately controlled on topical prescription therapies or when those therapies are not advisable. Secondary Objectives: To demonstrate the efficacy of dupilumab on additional itch endpoints in participants with PN, inadequately controlled on topical prescription therapies or when those therapies are not advisable. To demonstrate efficacy of dupilumab on skin lesions of PN. To demonstrate the improvement in health-related quality of life. To evaluate safety outcome measures. To evaluate immunogenicity of dupilumab.

Primary Outcome

WI-NRS is a validated measure of itch severity. Participants were asked daily to rate the intensity of their worst pruritus (itch) over the past 24 hours, using a 11-point scale ranging from 0 (no itch) to 10 (worst imaginable itch). Higher scores indicated more severity. Percentage of participants with improvement (reduction) in WI-NRS scores by \>=4 points from Baseline to Week 24 is reported in this outcome measure.
