BACKGROUND: Treatment options for peanut allergy are limited. In previous clinical trials, epicutaneous immunotherapy with a patch containing 250-mug peanut protein (Viaskin Peanut 250 mug [VP250]) was well tolerated and statistically superior to placebo in desensitizing peanut-allergic children.OBJECTIVE: To examine the safety of VP250 in children, using a study design approximating potential real-world use.METHODS: REALISE is a phase 3 multicenter study consisting of a 6-month, randomized, double-blind, placebo-controlled period followed by open-label active treatment. Children aged 4 to 11 years with physician diagnosis of peanut allergy received daily treatment with placebo (6 months) or VP250 (up to 36 months). Data from the 6-month, randomized, controlled phase of REALISE are reported.RESULTS: Three hundred ninety-three children were randomized 3:1 to receive VP250 (n=294) or placebo (n=99) for 6 months; 284 (72.3%) children had a history of peanut anaphylaxis. According to parent diary, all participants receiving VP250 and 83.8% receiving placebo reported at least 1 episode of local skin reaction, with frequency decreasing over time. Only 4 participants (1.4%) receiving VP250 discontinued due to adverse events. Epinephrine was administered for allergic reactions attributed to VP250 in 7 children (2.4%), of whom 5 remained in the study; none involved severe anaphylaxis. Overall adverse event rates were similar among participants with and without history of peanut anaphylaxis.CONCLUSIONS: In a study designed to mirror real-world use, VP250 was observed to be well tolerated in peanut-allergic children, consistent with previous phase 2b and 3 studies.
