Safety and Efficacy of Low-dose IL-2 in Birch Pollen Allergy

Summary

Several studies have reported a deficit and/or a defect in regulatory T cells in allergic subjects, which can be correlated with the allergic responses, especially for respiratory allergies. Low-dose IL-2 (ld-IL2) specifically targets and activates regulatory T cells (Tregs), which are cells that regulate immune responses. Thus by stimulating Tregs, ld-IL2 would control allergic responses. This study is designed to evaluate the efficacy of ILT-101 (ld-IL-2), compared to placebo, on the nasal response assessed by Total Nasal Symptom Score (TNSS) during a controlled birch allergen exposure.
