Aimmune Therapeutics, Inc.. (6/11/18). "Press Release: Aimmune Therapeutics Appoints Dr. Jayson Dallas as CEO". Brisbane, CA.

— Experienced Leader Brings Extensive Record of Global Strategic and Commercial Operational Accomplishments and Successful Product Launches —

Aimmune Therapeutics, Inc. (Nasdaq:AIMT), a biopharmaceutical company developing treatments for potentially life-threatening food allergies, today announced the appointment of Jayson Dallas, M.D., as President and Chief Executive Officer. Dr. Dallas, a biotech and pharmaceutical industry executive with decades of global strategic and commercial experience, will join Aimmune as President and CEO on June 19th, and will also become a member of the Aimmune Board of Directors.

Dr. Dallas succeeds Stephen Dilly, M.B.B.S., Ph.D., who announced his planned retirement late last year. Dr. Dilly will serve as a Special Advisor to Aimmune through the end of 2018 as Aimmune prepares for regulatory filings for AR101, its investigational biologic oral immunotherapy for desensitization of patients with peanut allergy.

“Jayson comes to Aimmune with both the physician’s focus on patient well-being and the commercial executive’s vision of how to build, innovate and deliver. With these attributes, we believe he’ll capably lead Aimmune to become a commercial company and advance additional food allergy therapeutic candidates into clinical development. We’re pleased that our comprehensive search led us to Jayson, and we’re looking forward to accompanying and supporting him on the transformative road ahead,” said Mark McDade, Chairman of the Aimmune Board of Directors. “At the same time, we want to express our gratitude to Stephen, who guided Aimmune’s evolution from an inspired, scrappy start-up to the standard-bearer in the emerging food allergy therapeutic space. He and his family have our very best wishes.”

Dr. Dallas joins Aimmune from Ultragenyx, a biopharmaceutical company focused on the development of products for rare and ultra-rare diseases, where he served as the company’s first Chief Commercial Officer. In nearly three years in that role, he oversaw commercial operations, including sales, marketing, reimbursement, and new product planning, and led the launches of Ultragenyx’s first two products, both of which received U.S. Food and Drug Administration (FDA) approvals in the past year.

Prior to his work at Ultragenyx, Dr. Dallas spent five years with Roche, as General Manager of Roche in the United Kingdom and as head of global commercial strategy groups at Genentech, focused on oncology, immunology and ophthalmology. Earlier, Dr. Dallas headed the specialty medicines operating unit for Novartis in the United States, after holding several leadership roles of increasing responsibility within the company. He also held significant medical and marketing positions as he built his career at Pfizer, Roche and Proctor & Gamble Pharmaceuticals. Before joining the pharmaceutical industry, Dr. Dallas practiced medicine in South Africa and the United Kingdom and worked as a research physician. Dr. Dallas earned an M.D. from the University of the Witwatersrand in Johannesburg, South Africa, and he subsequently acquired an MBA from Ashridge in Berkhamsted, United Kingdom.

“I’m thrilled to step into a company that is delivering on its commitment to the food allergy community to develop products that can improve people’s lives,” said Dr. Dallas. “Throughout my career, I’ve been driven by the need to bring effective treatments to patients and their families. It is an honor to have the opportunity to lead Aimmune to potentially offer the first treatment intended to protect people with peanut allergy from life-threatening reactions. I appreciate the phenomenal work that Stephen has done to build Aimmune into a fully integrated biotechnology company and I am extremely proud to be taking over at this exciting time.”

In the role of Special Advisor, Dr. Dilly will focus on the execution of Aimmune’s regulatory filings for AR101, which has FDA Fast Track Designation, as well as FDA Breakthrough Therapy Designation for peanut-allergic patients ages 4–17. Aimmune plans to submit a Biologics License Application (BLA) for AR101 to the FDA by the end of 2018, followed by a Marketing Authorisation Application (MAA) to the European Medicines Agency (EMA) in the first half of 2019.

“As Aimmune nears the turn toward potentially having its first product on the market, Jayson is the ideal leader to take the baton,” said Dr. Dilly. “I’m delighted to welcome him to Aimmune, and I’m excited to work closely with him to provide optimal continuity through the AR101 regulatory process. It has been a privilege to have been entrusted with building Aimmune and working to alleviate the impact of food allergies. I can confidently hand that charge over to Jayson, knowing that he will take it forward with clear-sighted resolve and care.”
