• Participants with a confirmed clinically allergic response to peanut.
• Positive clinical reaction during the peanut oral food challenge and no clinical reaction during the placebo challenge
• Positive peanut allergy skin prick test > 3 millimeters (mm) of the negative control and detectable serum peanut-specific Immunoglobulin E (IgE) levels by ImmunoCAP testing.
• Body mass index (BMI) of 18 to 36 kilogram per square meter (kg/m\^2) inclusive) and total body weight > 50 kg (110 lb). BMI = weight (kg)/(height [m\^2]).

• Male participants must be willing to use effective methods of contraception during the entire study period and for 15 weeks after the last administration of investigational product.

You may not qualify if…

• Have concomitant dermatological or medical condition(s) which may interfere with the Investigator's ability to evaluate the participant's response to the investigational product.
• Have experienced severe life-threatening anaphylactic reactions to peanuts within 6 months before screening (i.e., requiring an intensive care unit [ICU] admission).
• Positive clinical reaction observed during the placebo oral food challenge.
• Participation in any interventional study for the treatment of peanut and/or food allergies in the 12 months before screening.
• Have received any investigational product or been part of any interventional clinical study within a period of 3 months or 5 half-lives (whichever is longer) before screening.
• Have received systemic corticosteroids, nonsteroidal, immunosuppressant, or immunomodulating drugs treatments within 2 weeks before screening.
• Use of beta blockers, angiotensin-converting enzyme inhibitors, angiotensin-receptor blockers, or calcium channel blockers within 2 weeks before screening.
• History of ischemic cardiovascular diseases.
• Use of biologics within 6 months before screening or participant is in build-up phase of allergen immunotherapy (excluding peanut) and has not reached maintenance dose.
• Have received antibiotic treatment within 1 week before screening.
• Have a history of hypersensitivity or allergic reactions following infusions of human blood or blood components.
• Have a history of hypersensitivity or allergic reactions a component of etokimab formulation or the inactive ingredients (excipients).

• Other significant medical conditions that in the opinion of the Principal Investigator, prevent participation in the study.
• History of drug, alcohol or other substance abuse, or other factors limiting the ability to cooperate and to comply with the study protocol.
• Have any other physical, mental, or medical conditions which, in the opinion of the Investigator, make study participation inadvisable or could confound study assessments.
