Nasal microbiome in chronic sinusitis with nasal polyps
Part of Ear, nose & throat, Immune system & allergy clinical trials.
This study looks at how bacteria in the nose relate to a type of chronic sinusitis with nasal polyps. It may help find better treatments for this condition.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have chronic sinusitis with nasal polyps (CRSwNP), where a certain type of white blood cell (eosinophils) makes up more than 27% of the cells in your nasal tissue.
- You have not used steroid sprays or pills, or antileukotriene medications (like montelukast) for at least 4 weeks before your biopsy or surgery.
- You do not have other nasal conditions like allergic fungal sinusitis, cystic fibrosis, or primary ciliary dyskinesia.
- You are not allergic to aspirin (AERD).
- You do not smoke and are not pregnant.

This study looks for certain markers in your blood and nasal tissue that may be linked to chronic sinusitis with nasal polyps. It may help doctors understand the condition better and could lead to more targeted treatments in the future.
This study collects information from people with chronic rhinosinusitis and nasal polyps in both nostrils. By tracking patients over time, researchers hope to learn more about the condition and how to improve care.
This study looks at how thick or thin your nasal fluids are and checks for certain allergy/immune cells in your nose during surgery. It helps doctors understand the type of inflammation you have, which may guide better treatments.
This study compares two ways to treat chronic sinusitis with nasal polyps: giving a medicine that targets a specific type of inflammation (anti-IL-5 therapy) along with simple removal of polyps, versus a more extensive sinus surgery. The goal is to see which approach better controls your symptoms and reduces the need for repeat treatment.
This study looks at why people with nasal polyps lose their sense of smell and how it might come back. You may be able to join if you have had nasal blockage, runny nose, smell loss, or facial pain for at least 12 weeks, have polyps seen inside your nose, and are using a steroid spray regularly.
This study tests an injection called LP-003 that may help reduce nasal polyps and improve breathing. It's for people whose symptoms are not controlled by standard treatments like steroid sprays or surgery.
