Study of Dupilumab 300 mg Every Other Week After Endoscopic Sinus Surgery in Patients With Allergic Fungal Rhinosinusitis (AFRS) on a Background Therapy With Intranasal Corticosteroid Spray

• Status: WITHDRAWN
• Trial end date: 2024-07-17

Summary

Background:

Allergic fungal rhinosinusitis (AFRS) is a severe type of sinus infection. People with AFRS develop heavy mucus and growths called polyps that apply pressure to the sinuses and block their breathing. Surgery can remove the polyps, but they often grow back. Researchers want to test an approved drug they believe may help people with AFRS.

Objective:

To test a drug (Dupilumab) in people with AFRS.

Eligibility:

People aged 18 years or older with suspected AFRS who are scheduled to undergo surgery for nasal polyps.

Design:

Participants will have several tests before their surgery. They will have imaging scans of their sinuses. They will have an endoscopic exam: A tube with a camera and a light will be inserted into their sinuses. They may give blood and mucus samples. They will have standard treatment with nasal sprays for 2 to 6 weeks before their surgery.

Excess nasal tissue removed during the surgery will be collected for research. Then they will begin treatment with the study drug.

Dupilumab is injected under the skin. Some participants will receive the study drug. Some will receive a placebo injections. The placebo injections are just like the study drug but contain no medicine. Participants will not know which injections they are getting.

All participants will administer the injections to themselves at home. They will do this every 2 weeks for 1 year after the surgery. They will have a clinic visit 16 weeks after surgery.

Participants will have follow-up for 12 weeks after treatment ends.
