Induction of Sustained Unresponsiveness to Peanuts Using High- and Low-dose Peanut Oral Immunotherapy

This study is a continuation of a clinical trial NCT044155930 comparing the efficacy and safety of oral immunotherapy (OIT) with low or high doses of peanut protein (150 or 300 mg, respectively) and will involve patients who have accomplished their per-protocol participation in that trial. The aim of current study is to assess a sustained unresponsiveness (SU) to allergen protein after at least 8 months of previously assigned high- or low-dose peanut OIT, followed by 4-week-allergen avoidance, and verified by an open oral food challenge (OOFC).
