How eyes and nose react to grass allergy
Part of Ear, nose & throat, Eyes & vision, Immune system & allergy, Lungs & breathing clinical trials.
This study looks at how people with and without grass allergies react when a small amount of grass allergen is put into the eye. It aims to understand the immune response in the eyes and nose, which may help improve allergy treatments.

This trial tests if allergy shots (allergen-specific immunotherapy) can reduce symptoms of moderate to severe dust mite allergy. You will be in a room that exposes you to dust mites to see how well the treatment works, compared to a placebo.
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 Phase 3 trial tests whether an allergy treatment can reduce symptoms caused by grass and olive pollen. It also checks safety, especially for breathing and allergic reactions, in people with confirmed grass/olive allergy.
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 study looks at how well the grass pollen allergy treatment Grassmuno® works in everyday life. It is for adults with moderate to severe hay fever triggered by grass pollen, who may or may not have well-controlled asthma.
This trial tests an under-the-tongue tablet for people with dust mite allergies causing moderate to severe nasal symptoms or mild-to-moderate asthma. The goal is to see if it improves symptoms and can replace or reduce the need for allergy medicines.
