Read our Asthma research guide →Phase 2 — Testing in a bigger group (up to a few hundred people) to see if the treatment actually works and is still safe.
This trial is testing a new inhaled medication called to see if it can help people with mild allergic asthma. Researchers want to understand how well this treatment works at reducing the late asthmatic response—a delayed asthma reaction that happens hours after exposure to an allergen. About 36 people will participate, with half receiving the new medication and half receiving a placebo (a dummy treatment with no active drug).
Small airways deep in the lungs can be affected by allergies and asthma, and current treatments don't always work well enough to control the delayed asthma reactions that occur after allergen exposure. This trial is exploring whether this new medication might be more effective at preventing or reducing these delayed reactions.

If you join this study, you will be randomly assigned to either receive the new inhaled medication or a placebo (salt water). You'll visit the research center for breathing tests and allergen challenges—where doctors will have you breathe in a small amount of your known allergen to see how your airways respond. The researchers will measure your lung function and monitor you for asthma reactions, particularly the delayed response that happens several hours after allergen exposure. You'll complete various breathing tests and follow-up visits as outlined by the study team.
