Washed gut bacteria transplant for chronic nasal allergy symptoms
Treatments studied
Part of Ear, nose & throat, Immune system & allergy, Infections, Lungs & breathing clinical trials.
This trial tests whether transplanting specially washed gut bacteria from healthy donors can reduce nasal allergy symptoms like congestion, runny nose, itching, and sneezing. The transplant is given through a tube into the stomach or intestines, and could be a new way to treat chronic rhinitis.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 6 years old or older.
- You have two or more nasal symptoms (like congestion, runny nose, itching, or sneezing) for at least 1 hour every day.
- Your nasal symptoms score is 4 or higher, meaning symptoms are moderate to severe.
- You have not taken antibiotics, acid reducers, probiotics, or other drugs affecting gut bacteria in the last week.
- You are free of other nasal problems like chronic sinusitis, polyps, or a severely deviated septum.
- You are willing and able to undergo a gastroscopy or colonoscopy for the transplant procedure.

This trial tests a treatment called washed microbiota transplantation, which transfers gut bacteria from healthy donors to people with allergic rhinitis. The goal is to see if changing the gut bacteria can reduce allergy symptoms like sneezing, itching, and a runny or blocked nose.
This study uses a nasal allergen provocation test to help diagnose chronic rhinitis more accurately. If you have allergic rhinitis or are a healthy volunteer, you may help researchers learn how well this test works.
This trial tests if transplanting healthy nasal bacteria from a donor can help people with chronic sinusitis. It aims to restore a healthy microbiome in the nose to reduce symptoms like congestion and discharge.
This trial studies whether a yeast-based supplement can help manage ongoing allergic rhinitis (nasal allergy) symptoms like sneezing, runny nose, and itching. It's for people aged 18-35 who have symptoms most days for at least 4 weeks.
This Phase 2 study tests a “viral” treatment meant to reprogram the lining of your nose to reduce allergy-like immune responses. It is testing whether this approach is safe and can help people with cat allergy (with or without asthma) or compare against healthy people.
This study tests whether a daily probiotic (a type of beneficial bacteria) can help ease allergy symptoms like sneezing and a runny nose in children. If your child has allergies, this may offer a natural way to feel better.
