The primary purpose of this study is to assess the efficacy and safety of daily DBV712 250 micrograms (mcg) to induce desensitization to peanut in peanut-allergic children 4-7 years of age over a 12-month double-blind, placebo-controlled (DBPC) Treatment Period.
A Phase 3, Double-blind, Placebo-controlled, Randomized Study to Assess the Efficacy and Safety of Epicutaneous Immunotherapy With DBV712 250 μg in 4-7-year-old Children With Peanut Allergy (VITESSE)
This study is consisting of a 4-week Screening Period, 12-month DBPC Treatment Period and an open-label extension of either 24 or 36-months duration so that each participant may have the opportunity to receive DBV712 for a total duration of 36 months. Following 36 months of treatment with DBV712 250 mcg, sustained unresponsiveness (SU) will be evaluated by subsequent open food challenge(s) [FC(s)] at 2-, 4-, and 6-months off treatment.
Maximum participant participation will be either approximately 44 or 56 months, depending on the participant's randomized treatment assignment. During the 4-week Screening Period, participants are required to meet 2 sequential screening parameters to determine eligibility prior to randomization:
- Assessment of peanut skin prick test (SPT) and serum peanut immunoglobulin-E (IgE)
- Peanut double-blind placebo-controlled food challenge (DBPCFC) to confirm peanut allergy and establish an entry peanut eliciting dose (ED). Participants with a peanut protein ED less than or equal to (≤) 100 milligram (mg) will be eligible for randomization.
The starting dose of the eligibility peanut DBPCFC will be 1 mg peanut protein and will escalate up to a highest single dose of 100 mg peanut protein (cumulative 144 mg) via the following schedule: 1, 3, 10, 30, 100 mg. Participants who react, with an eliciting dose (ED) (with dose-limiting symptoms) at or below the dose of 100 mg peanut protein will be considered eligible.
Randomization of eligible participants will occur in a 2:1 ratio to DBV712 250 mcg (active treatment) or placebo, respectively.
