Condition overview

Peanuts are the second most common food allergy in children and it’s on the rise.1 Roughly 1.2 million children and teens in the United States — or just over 2% of the non-adult population — have peanut allergies.1 Although most life-threatening reactions are triggered by ingested foods, reactions can also come simply from skin contact, eye contact or smelling peanuts. About 20 percent of children outgrow peanut allergies. But those with one nut allergy have a 1:4 chance of being allergic to other nuts.2

Current treatments and cautions

Currently, the best treatment is total avoidance. This means:

  • Keep no peanut products on the premises because of other food contamination
  • Carry a supply of safe food when travelling
  • Learn to read labels carefully
  • Be aware that other nut products may present a risk
  • Tell family, caterers, and party hosts about the allergy well in advance of any gathering
  • Always carry an EpiPen®
  • Educate family members and caregivers about the signs of an anaphylactic reaction; teach them how to use an EpiPen
  • Wear a medic alert bracelet

New guidelines suggest introducing infants to peanuts between four and six months of age. This may make them less likely to develop peanut allergies than waiting until after the infant is 12 months of age.3

Overview

The FDA is expected to approve oral immunotherapy (OIT) products Palforzia (AR101) in 4Q2019 or 1Q2020, and Viaskin Peanut in 2020.

The peanut desensitizers may increase patient tolerance to peanuts; in clinical trials, patients who couldn’t tolerate a 1/3 of a peanut kernel could tolerate 2 to 4 peanut kernels after treatment with a peanut desensitizer. However, the risk of a systemic allergic reaction was higher in the treatment group than in the placebo group.

ICER concluded that neither of the peanut desensitizing agents offer a superior net health benefit compared to peanut avoidance.4

How effective are Palforzia (AR101), Viaskin and peanut oral immunotherapy (OIT) compared to no treatment?4

*A greater proportion of patients treated with Viaskin achieved desensitization compared to the no treatment arm, however the predefined primary outcome of the trial was not met.

** In studies of Palforzia (AR101), Viaskin, peanut OIT, epinephrine use and systemic allergic reactions increased.
