简要总结
The goal of this study is to test the efficacy of Dupixent in improving post-burn itching symptoms versus the current standard of care.
详细描述
Participants will receive six injections of Dupixent or placebo (two 300 mg loading doses and one 300 mg dose every two weeks after that).
In addition, participants will be asked to complete questionnaires to determine daily itch severity, quality of life, treatment benefit, physical functioning, and pain interference.
Individual participants will require 13 weeks to complete all study visits.

盲法说明
The study sponsor will supply all study drug (including placebo) as blinded kits. Study staff, investigators, and participants will be blinded to which treatment condition a participant has been randomized to. Note that the drug manufacturer will email codes to the pharmacists (who are unblinded) identifying the appropriate study drug for a particular participant. It is possible that participants may become unblinded to the obvious physical effects related to receiving Dupixent or placebo (pruritus improves or does not improve). Study staff will not discuss or speculate potential treatment arm allocation with participants based on participants' comments, questions, daily itch diary data, or physical observation. Study staff will encourage participants expressing resentful demoralization to remain in the study through their final visit.
