Study to Evaluate Dupilumab Monotherapy in Pediatric Patients With Peanut Allergy

The primary objective of the study is to assess the tolerability of peanut protein in pediatric patients (6-17 years old) treated with dupilumab monotherapy, in which tolerability is defined as the proportion of patients who safely pass a double-blind placebo-controlled food challenge (DBPCFC) at week 24. The secondary objectives are: * To determine whether dupilumab treatment improves peanut tolerability, defined as a change in the cumulative tolerated dose (log transformed) of peanut protein during a DBPCFC * To evaluate the safety and tolerability of dupilumab treatment in peanut allergic patients * To evaluate the effects of dupilumab treatment on the levels of peanut-specific Immunoglobulin E (IgE) * To evaluate the treatment effect of dupilumab on the average wheal size after a titrated skin prick test (SPT), as measured by area under curve (AUC) of the average wheal size induced by peanut extract at different concentrations * To assess the incidence of treatment-emergent anti-drug antibodies (ADA) to dupilumab in patients over time
