Study to understand cat and birch allergies in adults and children
Part of Eyes & vision, Immune system & allergy clinical trials.
This study looks at how allergic reactions to cat or birch allergens affect people. It aims to find and describe adults and children with these allergies, which may help develop better treatments.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You (or your child) must be at least 5 years old and weigh at least 22 pounds if under 18.
- You must have a history of allergy to cats (for Part A) or birch pollen (for Part B), confirmed with a skin prick test.
- If joining the cat part, you must not live with a cat now and must not have had a cat in your home for the past year.
- No current eye disease or condition that could interfere with the tests.
- No history of a life-threatening asthma attack requiring a breathing tube or causing serious breathing failure.
- No active chronic infections requiring long-term antibiotics, antivirals, or antifungal medicine.

Other trials that look related to this one.
This trial tests an injectable treatment that may help manage eye allergy symptoms caused by cat allergies. It aims to see if the treatment is safe and effective for adults and children, and includes a controlled cat exposure challenge.
This study looks at how older adults (60+) with different histories of birch pollen allergy tolerate nasal exposure to birch pollen. It may help researchers understand why some people lose their allergy symptoms with age.
This Phase 1 study looks at how the immune system drives allergic airway inflammation in people with allergic asthma, and compares them with allergic non-asthma and non-allergic healthy volunteers. The goal is to identify immune “signals” and cell “receptors” involved, which may guide better future treatments.
This study looks at lymph nodes in the neck to understand how the body responds to cat allergy treatments. It may help researchers improve allergy shots or other therapies for people with cat allergies.
This study looks at your blood to find allergy-related antibodies if you have pollen allergies to grass or birch. It may help researchers better understand what in the immune system drives allergy symptoms.
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.
