The FDA's Allergenic Products Advisory Committee voted 7 –2in favoron efficacy and 8-1 in favor on safety for use of AR101 to reduce the incidence and severity of peanut allergy reaction in patients aged 4-7. It is likely AR101 will be approved with a REMS program that will require a prescription for epinephrine. Aimmune is considering pricing AR101 between $3,000 and $20,000 when the drug is approved. As a comparison, the current discounted price for grass and pollen allergy products is $5,000 a year.An FDA review of the drug found that despite both placebo and AR101 groups following a peanut avoidance diet, the AR101 group had an increased number of discontinuations, systemic allergic reactions and reports of eosinophilic esophagitis, but reduced the need for treatment after accidental exposure.
