Peanut Allergy Drug Will Protect Children, Experts Tell F.D.A.

The new drug, called Palforzia and made by Aimmune Therapeutics, is an oral immunotherapy regimen that aims to reduce sensitivity to peanut allergens.

But the treatment does not work for everyone, and is accompanied by side effects, including severe allergic reactions to the peanut exposure. Twenty percent of the children in the trial who received the treatment withdrew because of adverse events; 14 percent had severe allergic reactions that required treatment with epinephrine, compared with only 6.5 percent who received a placebo.

The regimen begins with trace amounts of the protein that are carefully measured and increased incrementally under medical supervision as tolerance develops.

It might also relieve some of the fear and anxiety that some people feel about the possibility of experiencing the effects of a severe peanut allergy.
