U.S. FDA Accepts BLA Filing of Aimmune Therapeutics’ AR101 for Peanut Allergy

-- If Approved, AR101 Will Be the First Medicine for This Life-Threatening Condition --

BRISBANE, Calif.--(BUSINESS WIRE)--Mar. 18, 2019-- Aimmune Therapeutics, Inc. (Nasdaq: AIMT), a biopharmaceutical company developing treatments for life-threatening food allergies, today announced that the Biologics License Application (BLA) for AR101 has been accepted for review by the U.S. Food and Drug Administration (FDA).

“Today is a significant milestone for Aimmune. The FDA’s acceptance of our BLA is a crucial step forward in delivering AR101 to children, teens and families living with the serious, daily risk of allergic reactions to accidental exposure to peanuts,” said Jayson Dallas, M.D., President and Chief Executive Officer of Aimmune. “We are working with the FDA to complete their review as expeditiously as possible given that there are currently no approved medicines for peanut allergy.”

Aimmune is developing AR101 as a treatment to reduce the risk of anaphylaxis following accidental exposure to peanut. The FDA granted AR101 Breakthrough Therapy Designation in June 2015 for peanut-allergic children and adolescents ages 4-17, which was preceded by the granting of Fast Track Designation in September 2014. Both of these programs support expedited review of new drugs and biologics.

The FDA has informed Aimmune that the BLA will be reviewed under a twelve-month target review period, as measured from the January 2019 start date. As a consequence, review of the BLA may take until late January 2020. Aimmune is currently engaged in discussions with the FDA regarding the review timeline for the AR101 BLA. The FDA expects to convene an advisory committee meeting to discuss the application.

“Every day in the United States, more than one million children and teens with peanut allergy are at risk that exposure to food allergens could lead to potentially life-threatening reactions,” said Daniel Adelman, M.D., Chief Medical Officer of Aimmune. “Published epidemiologic studies and everyday experiences of this community show that for many, avoidance of peanuts is not enough. There is an urgent need for a rigorously developed, clinically proven medicine like AR101 that can help protect people when accidental exposures do occur.”

Aimmune’s BLA is comprised of extensive clinical as well as chemistry, manufacturing and controls (CMC) data. Specifically, data from the pivotal phase 3 PALISADE trial of AR101, the largest and only successful phase 3 trial in peanut allergy, were published in the New England Journal of Medicine and demonstrated that AR101 treatment resulted in a significant increase in the amount of peanut protein tolerated compared to placebo. The data suggest that AR101-treated patients could expect fewer and less severe reactions to accidental peanut exposures. Data from the phase 3 RAMSES trial confirmed the safety profile of AR101 first observed in the PALISADE study; both trials are part of the application submission.
