Injection for severe seasonal allergy symptoms
Part of Ear, nose & throat, Immune system & allergy, Lungs & breathing clinical trials.
This study tests an investigational injection (GR1802) that may help reduce seasonal allergy symptoms when standard allergy medications aren't enough. If you qualify, you'll receive the injection during the pollen season to see if it improves your sneezing, runny nose, and itchy eyes.
Summary written for real people, not researchers, by Clin2.
