Allergy spray study for hay fever
Part of Ear, nose & throat, Immune system & allergy, Lungs & breathing clinical trials.
This trial is studying the bacteria in your nose and mouth during treatment with an allergy spray placed under your tongue. The goal is to understand how this treatment affects your allergy symptoms and your body's natural defenses.
Summary written for real people, not researchers, by Clin2.

This study looks at how sublingual immunotherapy tablets, which are placed under the tongue, affect the body's response to dust mite allergies in people with allergic rhinitis. The goal is to understand how these tablets might change the immune system and help improve symptoms.
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 trial tests if a traditional Chinese medicine called ZhenQiFuZheng can help people with allergic rhinitis by changing their gut bacteria. Researchers will collect samples to understand how it works.
This phase 3 trial tests a specific allergy treatment (an “immunotherapy” shot) for people whose symptoms are triggered by grass and cypress tree pollen. It aims to see if the treatment is safer and more effective at reducing allergy symptoms over time, especially for nose/eye symptoms and some people with asthma.
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 study tests a daily under-the-tongue tablet or drops to reduce allergy symptoms caused by house dust mites. If you have allergic rhinitis and are bothered by dust mites, this treatment might help your nose feel better without needing shots.
