ClinConnect Summary
This clinical trial is looking at how a medication called dupilumab affects the barrier function of the nasal lining in patients with chronic rhinosinusitis (CRS), which can occur with or without nasal polyps. The researchers want to understand how this condition impacts the nasal lining and how dupilumab treatment might help improve it. Participants will be involved in tests that examine the function of their nasal cells and the overall health of their nasal passages.
To join the study, participants must be between 18 and 99 years old and have been diagnosed with chronic rhinosinusitis. There are two groups: one with nasal polyps and one without. Some people may not be eligible, such as those who are pregnant, have certain medical conditions, or have had recent severe flare-ups of their condition. Those who take part can expect to provide samples for research and receive treatment with dupilumab, which aims to help improve their nasal symptoms. This study could help doctors better understand how to treat chronic rhinosinusitis in the future.
