Study of pollen, climate, and air pollution effects on nose symptoms
Part of Ear, nose & throat, Immune system & allergy, Lungs & breathing clinical trials.
This study looks at how pollen, climate, and air pollution affect people with seasonal allergies (chronic rhinitis). It aims to see if these factors worsen symptoms and could help improve allergy care.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must live in one of the study cities (like Malaga, Milan, Luxembourg, Thessaloniki, Lodz, Berlin, Toulouse, Chernivtsi, or Brasov).
- You have had nose allergy symptoms during pollen season for at least 3 years, while living in the same home and going to the same school or job.
- A skin prick test and a blood test must show you are allergic to olive, grass (timothy), or birch pollen.
- If you are allergic to other things, your nose symptoms must only happen or clearly get worse during the pollen season of the allergens of interest.
- You cannot have had allergy shots (immunotherapy) in the last 5 years, nor take certain medications (like immunosuppressants or biologics) in the last 6 months.
- You must not have chronic sinusitis or other severe medical conditions that might interfere with the study.

This study looks at different “immune inflammation patterns” in people with asthma and/or nasal polyps. It may help researchers better tailor future treatments by figuring out which patterns go with which symptoms.
This study follows people with moderate-to-severe asthma and repeatedly checks how their lungs and symptoms relate to environmental exposures over time. It may help researchers better understand what triggers asthma and how exposures affect asthma control.
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 looks at how people with allergic rhinitis (hay fever) seek help and how that relates to their mental health. Researchers hope to learn more about the connection between allergies, anxiety, and depression over time.
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 creates a biorepository to collect and store samples (blood, nasal fluid, skin swabs) from people with allergies, asthma, sinus disorders, or immune dysregulation. It aims to better understand these conditions over time, which may help develop better treatments.
