Primary Outcome Measures

Name	Time	Method
Main Objective: The primary objective is to demonstrate the efficacy of AR101, a pharmaceutical-grade peanut allergen formulation, through reduction in clinical reactivity to limited amounts of peanut allergen in peanut-allergic children and adolescents (ages 4 to 17 years, inclusive).;Secondary Objective: The secondary objectives are to demonstrate the safety of AR101 as measured by the incidence of adverse events (AEs), including serious adverse events (SAEs) and to evaluate the immunological effects of peanut OIT therapy.;Primary end point(s): The primary clinical efficacy endpoint is the proportion of subjects who tolerate at least 2043 mg cumulative of peanut protein with no more than mild symptoms at the Exit DBPCFC.;Timepoint(s) of evaluation of this end point: After approximately 56 weeks of treatment including up to 16 weeks at maintenance dose of 300mg/day.
