FDA Approves the First Drug for Treatment of Peanut Allergy in Children

The US Food and Drug Administration has approved Palforzia [Peanut (Arachis hypogaea) Allergen Powder-dnfp] for the treatment of allergic reactions that could occur with accidental exposure to peanuts.

Palforzia can be initiated in patients aged 4 to 17 years old with confirmed diagnosis of peanut allergy. Along with treatment, patients must continue to avoid peanut exposure.

Treatment with Palforzia consists of 3 stages. The initial dose escalation phase occurs over a single day. The up-dosing phase consists of 11 increasing dose levels given to the patient over several months. The initial dose escalation and first dose of each up-dosing doses are administered by healthcare professionals. When the patient completes all up-dosing levels, they begin the daily maintenance dose stage.

The effectiveness of the new option was evaluated in a randomized, double-blind, placebo-controlled study involving approximately 500 peanut-allergic individuals. Overall, 67.2% of those given Palforzia tolerated 600 mg doses of peanut protein compared with 4.0% of those in the placebo group.

The safety of the new option was evaluated in 2 double-blind, placebo-controlled studies involving approximately 700 peanut-allergic patients. The most commonly reported adverse effects were abdominal pain, vomiting, nausea, tingling in the mouth, itching, cough, runny nose, throat irritation, hives, wheezing, shortness of breath, and anaphylaxis.
