Summary

ITN049AD (LEAP-On) Study is a continuation of the ITN032AD LEAP Study (NCT00329784). Peanut Allergy, a recognized public health concern, is a common and potentially life-threatening food allergy for which there is no treatment. ITN032AD (LEAP) Study evaluated whether early exposure to peanut promotes tolerance and provides protection from developing peanut allergy in children who are allergic to eggs or who have severe eczema. ITN049AD (LEAP-On) Study will evaluate persistent tolerance to peanut by assessing the effect of twelve months of cessation of peanut consumption in LEAP Study participants who consumed peanut and those who avoided peanut over the previous five years.
