Asthma drug could stop cat allergy sneezes in their tracks
NCT ID NCT06069063
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This small Phase 2 trial tests whether a single dose of zafirlukast, an asthma drug, can prevent nasal symptoms caused by cat dander. Twelve adults with cat allergies will receive either the drug or a placebo before being exposed to cat dander in a controlled setting. Their symptoms will be tracked for four hours to see if the drug makes a difference.

- What this could lead to
- If it works, this could point toward a new way to prevent allergy symptoms from cats using an already-approved asthma drug.

- This is a very small early-stage trial with only 12 people. It may not work as hoped, and results may not apply to real-world cat exposure.
