California-based Aimmune Therapeutics sparked optimistic headlines after releasing clinical trial results that its allergy product, AR101, would reduce the risks linked to an accidental exposure to peanuts.
Aimmune’s “peanut pill” is modeled on the oral therapies some specialists use to wean allergic kids back on to nuts. This approach has gained popularity in recent years, especially for children with multiple allergies, or when it’s a substance particularly hard to avoid.
Childhood peanut allergy diagnoses increased more than 20% in the United States from 2010 to 2017. The global market for relief is worth as much as $2 billion. The French drugmaker DBV Technologies is also working to commercialize a peanut allergy patch. Other companies, including industry giant Sanofi, are following their lead.
