Aeglea BioTherapeutics Announces Leadership Change

AUSTIN, Texas, July 20, 2017 -- Aeglea BioTherapeutics, Inc. (NASDAQ:AGLE), a biotechnology company committed to developing enzyme-based therapeutics in the field of amino acid metabolism to treat rare genetic diseases and cancer, today announced that David G. Lowe, Ph.D., resigned as the company’s president, chief executive officer and director, effective immediately. Anthony Quinn, M.B Ch.B, Ph.D., has been appointed to serve as interim chief executive officer while the company conducts a comprehensive search for a permanent chief executive officer.

Dr. Quinn has played a significant role in the leadership of Aeglea. He has been a member of the board of directors since 2016 and recently served as interim chief medical officer. With more than 20 years’ experience in the pharmaceutical and biotech industries, Dr. Quinn has an accomplished track record as a drug developer. He served as head of R&D and chief medical officer at Synageva BioPharma Corp. until the company’s acquisition by Alexion Pharmaceuticals in 2015. During his tenure at Synageva, he played a key role in securing European and U.S. approvals of Kanuma™ for Lysosomal Acid Lipase Deficiency and in building the company’s research and development organization and rare disease drug pipeline. Prior to Synageva, he was head of clinical research and exploratory development at Roche, which included leadership responsibility for the inflammation disease portfolio including the Mabthera^TM, Rituxan^TM and Actemra^TM programs.

“In addition to his seasoned leadership, Anthony brings broad experience in drug development, particularly in rare genetic disease. This will be critical to Aeglea’s future success as we continue to advance our preclinical and clinical pipeline,” said Armen Shanafelt, Ph.D., chairman of Aeglea’s board of directors. “With our strong management team, we are confident Anthony will provide continuity of leadership while we undergo a search for a permanent CEO.”

Dr. Shanafelt added, “It has been a privilege to work with David and I’d like to thank him for all that he has accomplished with Aeglea over the last several years through his hard work and passion for the company. We wish him well on the next phase of his career.”

Under Dr. Lowe’s leadership, Aeglea progressed from a preclinical-stage to a clinical-stage company, with three ongoing clinical trials in rare genetic disease and cancer. He played a key role in securing institutional financing for Aeglea, including a successful initial public offering in 2016.

“It has been an honor to work with the team at Aeglea,” said Dr. Lowe. “I am proud that we have established such a strong foundation to further Aeglea’s mission of providing new therapies that address unmet needs in rare genetic diseases and cancer.”
