Eligibility
Key inclusion criteria
Key

1. Signed informed consent and/or assent (where applicable) was obtained prior to study participation. Participant (and parent/legal guardian) was able to understand and provide informed consent and assent, as applicable. If a minor participant providing assent reaches the age of legal majority (as defined by local law), he/she was re-consented (ICF) at the next study visit.
2. Male or female participants who were 6 to 55 yrs of age at the time of signing informed consent/assent.
3. Documented medical history of allergy to peanuts or peanut-containing foods.
4. Positive peanut-specific IgE (peanut sIgE), = 0.35 kUA/L at Screening Visit 1.
5. Positive SPT for peanut allergen at Screening Visit 1. This is defined as the average diameter (longest diameter and mid-point orthogonal diameter) = 4 mm wheal compared to the negative control.
6. A positive peanut DBPCFC at baseline (Screening Visit 2, Part 1 and Part 2 DBPCFC) defined as the occurrence of dose-limiting symptoms at a single dose = 100 mg of peanut protein. Eligibility to proceed with the DBPCFC requires presence of all inclusion and absence of all exclusion criteria.
7. Participants must weigh = 20 kg at Screening Visit 1.
8. Participants must be able to receive injections (study treatment), participate in the DBPCFC, and must be willing to continue avoiding exposure to peanuts and any other foods that they are allergic to throughout this study.

Key exclusion criteria
1. History of hypersensitivity to ligelizumab or its excipients, or to other biologics (i.e., to murine, chimeric or human antibodies).
2. Hypersensitivity or intolerance to any of the matrix components used within the material for the oral food challenge.
3. History of severe or life-threatening hypersensitivity event needing an ICU (intensive care unit) admission or intubation within 60 days prior to baseline DBPCFC (Screening Visit 2).
4. Total IgE >2000 IU/mL at Screening Visit 1.
5. Participants with uncontrolled asthma (according to Global Initiative for Asthma (GINA) guidelines, GINA 2020) who meet any of the following criteria:

* FEV1 <80% of participant's predicted normal value at Screening Visit 1
* One hospitalization for asthma within 12 months prior to Screening Visit 1
6. Current or previous history of a mast cell disorder, including mastocytosis.
7. Platelets < 100'000/µL at Screening Visit 1.
8. Female participants not on oral contraception with a stable dose for a minimum of 3 months prior to taking study treatment.
9. Participants with evidence of helminthic parasitic infection as evidenced by stools being positive for a pathogenic organism according to local guidelines at Screening Visit 1 (before start of Screening Visit 2). If stool testing is positive for pathogenic organisms, the participant should not be randomized and should not be allowed to be rescreened.
