AR101

Company Enters into Commercial Supply Agreement for AR101

BRISBANE, Calif. (BUSINESS WIRE) — May 16, 2019
Aimmune Therapeutics, Inc. (Nasdaq: AIMT), a biopharmaceutical company developing treatments for life-threatening food allergies, today announced that it has been informed by the U.S. Food and Drug Administration (FDA) that the Allergenic Products Advisory Committee (APAC) will review the Biologics License Application (BLA) for AR101 at its meeting scheduled for September 13, 2019. Aimmune is developing AR101, an investigational biologic drug for use in oral immunotherapy, as a treatment to reduce the frequency and severity of adverse events, including anaphylaxis, following exposure to peanuts. Additionally, Aimmune has entered into a commercial supply agreement with CoreRx, Inc., the Company’s long-standing manufacturer of AR101.

Peanut allergy is one of the most common food allergies, affecting more than 1.6 million children and teens in the United States.1 It can be a chronic and life-long condition, and reactions to peanut are severe and potentially life-threatening.2 The threat of a severe reaction dominates families’ daily lives and interferes with their quality of life.

“We have been preparing diligently, and will continue to refine our preparations, for the September 13 APAC Meeting so that we are in the best position to introduce AR101 to patients and their families as the first-ever approved treatment for peanut allergy, indeed for any food allergy,” said Jayson Dallas, M.D., President and Chief Executive Officer of Aimmune. “As we have previously communicated, we will be ready to launch AR101 by the fourth quarter of this year. Our agreement with CoreRx will allow the manufacturing of commercial AR101 supply to begin this week and will ensure that there is sufficient supply at launch.”

The FDA accepted the BLA for AR101 in March 2019, and previously informed Aimmune that completion of its review would be targeted by late January 2020. The FDA granted AR101 Fast Track Designation in September 2014 and Breakthrough Therapy Designation in June 2015 for peanut-allergic children and adolescents ages 4 to 17.

Aimmune’s AR101 commercial manufacturing facility, located on the CoreRx campus, includes state-of-the-art air-handling systems and equipment to prevent cross contamination of allergens, along with controls and management systems to ensure safety and compliance with U.S. and European pharmaceutical manufacturing regulations. The CoreRx team has been responsible for the manufacture of AR101 supply through the entire clinical development program.

About AR101

AR101 is a new, investigational biologic drug for use in oral immunotherapy in patients with peanut allergy. The drug, which is manufactured in accordance with current Good Manufacturing Practices (cGMP), delivers a daily dose of peanut protein with a consistent protein profile, analyzed to ensure reliable major allergen content. The amount of active ingredient in each AR101 capsule is controlled to ensure minimal variability of allergen content across doses of a given strength. AR101 is administered as an oral powder in graduated doses in pull-apart capsules or foil-laminate sachets. The contents are mixed thoroughly with a few spoonfuls of age-appropriate, unheated food of the patient’s choice.

About Aimmune Therapeutics

Aimmune Therapeutics, Inc., is a biopharmaceutical company developing oral treatments for life-threatening food allergies. The company’s Characterized Oral Desensitization ImmunoTherapy (CODIT™) approach is intended to provide meaningful levels of protection against allergic reactions resulting from exposure to food allergens by desensitizing patients with defined, precise amounts of key allergens. Aimmune’s first investigational biologic product, AR101, is being developed as a treatment to reduce the frequency and severity and adverse events, including anaphylaxis, following exposure to peanuts. The BLA for AR101 is under review by the FDA, which in 2015 granted AR101 Breakthrough Therapy Designation for the desensitization of peanut-allergic patients 4 to 17 years of age. Aimmune expects to file for marketing approval of AR101 in Europe in mid-2019. Aimmune has filed an IND application for its second product, AR201 for the treatment of egg allergy, and intends to start a randomized phase 2 clinical trial in mid-2019.
