New shot aims to tame worst seasonal allergies

This study is testing whether an investigational injection called LP-003 can reduce symptoms in adults with moderate-to-severe seasonal allergies (hay fever) that aren't well controlled by standard allergy medicines. It's a large, late-stage trial comparing the injection to a placebo (a dummy shot) in 546 participants. The main goal is to see if the injection safely lowers daily scores for nasal symptoms like congestion, sneezing, and runny nose during peak pollen season.
