Lead Sponsor
University Hospital, Lille
Brief Summary

Drug Reaction with eosinophilia and Systemic Symptoms (DRESS) is a rare and severe multiorgan drug reaction whose pathophysiological mechanisms underlying remain unclear, but may involve the role of several immune cells like eosinophils. iIndeed,the number of eosinophils is increased in blood and/or in organs tiisues in at least 50% of patients with DRESS. There is no specific treatment available. The standard of care is corticosteroids, but they may be inefficient or poorly tolerated. The aim of this research is to find out whether a specific treatment of the immunological response in DRESS syndrome would be useful in combination with corticosteroids to speed up the recovery from DRESS syndrome and therefore reduce the total length of your hospital stay when your illness is being managed. This a multicenter, international, prospective, interventional study, double-blinded, placebo-controlled, randomized, in two balanced parallel groups, one receiving the standard of care (topical or systemic corticosteroids, according to the severity of DRESS syndrome) and the other one corticsoteroids and a targeted therapy against eosinophils (benralizumab, already available in other eosinophilic diseases like asthma).
