This is a 52-week, Phase 3 multi-center, randomized, double-blind and placebo-controlled study to assess the safety and clinical efficacy of two dosing regimens of ligelizumab (240 mg and 120 mg) subcutaneous injection every 4 weeks (SCq4w) in participants with a medically confirmed diagnosis of IgE-mediated peanut allergy. Participants will be randomized to ligelizumab 240 mg, ligelizumab 120 mg, or placebo (5 treatment arms, randomization ratio of 2:2:2:2:1) for the double-blind placebo-controlled treatment period (up to Week 12). Participants initially assigned to the 8-week placebo arms will receive the first dose of blinded ligelizumab treatment at the Week 8 visit. Participants initially assigned to the 16-week placebo arm will receive the last dose of placebo before the double blind placebo controlled food challenge (DBPCFC) at week 12 and the first dose of blinded ligelizumab treatment at the Week 16 visit.
