The peanut allergy treatment Palforzia® will be discontinued on July 31, 2026, according to its manufacturer, Stallergenes Greer.
Palforzia is the only oral immunotherapy (OIT) for food allergy approved by the U.S. Food and Drug Administration. It treats peanut allergy in children ages 1 through 17.
The notice on Stallergenes Greer’s Palforzia website reads: “This voluntary discontinuation is not related to product safety, quality, or efficacy.” As Palforzia winds down, Stallergenes Greer says it will support an orderly transition for healthcare professionals who prescribe the treatment and patients currently receiving the therapy.
Palforzia earned FDA approval in 2020. It was originally developed by Aimmune. Nestle Health Science bought Aimmune and then sold Palforzia to Stallergenes Greer.
Allergy & Asthma Network asked board-certified allergist and spokesperson Purvi Parikh, MD, to comment on the loss of Palforzia.
“It is disappointing to lose an oral immunotherapy option for peanut allergy — a condition that has increased in severity as well as incidence over time,” Dr. Parikh says. “While methods such as early introduction have helped prevent peanut allergy, this was the only FDA-approved immunotherapy option for children who already had a developed peanut allergy.
“The benefit of FDA approval is increased access to treatments and insurance coverage for these treatments. I hope we see more FDA-approved immunotherapy options on the horizon for our food allergy community.”
The peanut allergy treatment Palforzia® will be discontinued on July 31, 2026, according to its manufacture.
