Summary
This trial is testing a drug called dupilumab, along with other medications, in adults with a blood disorder called hypereosinophilic syndrome (HES). People who are already taking
Who is the study for?
Adults over 18 with Hypereosinophilic Syndrome (HES) who are partially responding to current eosinophil-depleting drugs like mepolizumab, reslizumab, or benralizumab. Participants will undergo various tests and must be willing to self-inject dupilumab regularly.
What is being tested?
The trial is testing the effectiveness of adding dupilumab to existing treatments for HES. Over a period of up to 48 weeks, participants will receive injections alongside their standard medication and attend clinic and remote visits.
What are the potential side effects?
Dupilumab may cause injection site reactions, eye problems such as dryness or irritation, joint pain, cold sores in your mouth or on your lips, and allergic reactions that can include rash or swelling.

Experimental Treatment
Group I: Dupilumab in addition to mepolizumab, reslizumab, or benralizumab (at least 24 but up to 48 weeks)Experimental Treatment1 Intervention
Dosing for an individual will be determined based on the nature of their residual symptoms and the FDA-approved dosing for that indication. Patients will self-administer using pre-filled syringes with needle shield or pre-filled pens. Patients with asthma and/or atopic dermatitis will receive a loading dose of 600 mg subcutaneously (followed by 300 mg SC every 2 weeks. Patients with Chronic Rhinosinusitis with Nasal Polyposis will not receive a loading dose and will be treated with 300 mg subcutaneously every 2 weeks. Patients with Eosinophilic Esophagitis will not receive a loading dose of 600 mg subcutaneously and will be treated with 300 mg subcutaneously weekly. Patients who meet criteria for more than one indication will be treated with the higher dose.
