Main Inclusion Criteria:

1. Male or female children aged 4 through 11 years;

2. Physician-diagnosis of peanut allergy or children with a well documented medical
history of IgE-mediated symptoms after ingestion of peanut and currently following a
strict peanut-free diet, but without a physician diagnosis;

3. Peanut-specific IgE level (ImmunoCAP system) >0.7 kU/L;

4. Positive peanut skin prick test (SPT) with a largest wheal diameter:

- ≥6 mm for children 4 through 5 years of age at Visit 1,

- ≥8 mm for children 6 years and above at Visit 1;

5. Positive DBPCFC at ≤300 mg peanut protein.

Main Exclusion Criteria:

1. History of severe anaphylaxis to peanut with any of the following symptoms:
hypotension, hypoxia, neurological compromise (collapse, loss of consciousness or
incontinence);

2. Generalized dermatologic disease

3. Diagnosis of mast cell disorders, including mastocytosis or uricaria pigmentosa as
well as hereditary or idiopathic angioedema;

4. Diagnosis of asthma that fulfills any of the following criteria:

- Uncontrolled persistent asthma as defined by National Asthma Education and
Prevention Program Asthma guidelines 2007 or by Global Initiative for Asthma
guidelines 2015,

- Asthma treated with either a high daily high dose of inhaled corticosteroid or
with a combination therapy of a medium or high daily dose of inhaled
corticosteroid with a long acting inhaled β2 agonist or with a combination
therapy of a high daily dose of inhaled corticosteroid with a long acting inhaled
β2 agonist. Asthmatic subjects treated with a medium daily dose of inhaled
corticosteroids are eligible. Intermittent asthmatic subjects who require
intermittent use of inhaled corticosteroids for rescue are also eligible,

- Two or more systemic corticosteroid courses for asthma in the past year or 1 oral
corticosteroid course for asthma within 3 months prior to Visit 1, or during
screening period,

- Prior intubation/mechanical ventilation for asthma within 1 year prior to Visit
1, or during screening;

5. Receiving β-blocking agents, angiotensin-converting enzyme inhibitors,
angiotensin-receptor blockers, calcium channel blockers or tricyclic antidepressant
therapy;

6. Received anti-tumor necrosis factor drugs or anti-IgE drugs (such as omalizumab) or
any biologic immunomodulatory therapy within 1 year prior to Visit 1, during screening
period or during study participation;

7. Use of systemic long-acting corticosteroids within 12 weeks prior to Visit 1 and/or
use of systemic short-acting corticosteroids within 4 weeks prior to Visit 1 or during
screening;

8. Prior or concomitant history of any immunotherapy to any food;

9. Receiving or planning to receive any aeroallergen immunotherapy during their
participation in the study. Aeroallergen immunotherapy must be discontinued at the
time of Visit 1;

10. Any disorder in which epinephrine is contraindicated such as coronary artery disease,
