Gliadin is the major allergen of wheat-dependent exercise-induced anaphylaxis (WDEIA). YH-35324 (lesigercept, GI-301) is a long-acting IgEtrap-Fc fusion protein that targets FcεR1α that could serve as a therapeutic approach in WDEIA. It is under development by Yuhan Corp. in early clinical trials as an allergy treatment.
