Aeglea BioTherapeutics Reports Third Quarter 2019 Financial Results and Corporate Highlights

AUSTIN, Texas, Nov. 06, 2019 (GLOBE NEWSWIRE) -- Aeglea BioTherapeutics, Inc. (NASDAQ:AGLE), a clinical-stage biotechnology company that engineers next-generation human enzymes to provide solutions for diseases with unmet medical need, today reported financial results for the third quarter ended September 30, 2019 and corporate highlights.

“We are excited about our pivotal Phase 3 PEACE trial in Arginase 1 Deficiency (ARG1-D), given the positive 20-dose data from our completed Phase 1/2 trial and ongoing Phase 2 open-label extension trial for pegzilarginase in patients with ARG1-D,” said Anthony G. Quinn, M.B Ch.B, Ph.D., president and chief executive officer of Aeglea. “Additionally, we are delighted to welcome Dr. Ravi Rao as chief medical officer and Mike Hanley as chief commercial officer, key executive leadership team additions who will help shape our future and continue the momentum of our ARG1-D, homocystinuria and cystinuria programs.”

Recent Highlights

  • Aeglea presented positive 20-dose data on 14 patients from the Company’s completed Phase 1/2 trial and ongoing Phase 2 open-label extension (OLE) trial for pegzilarginase in patients with ARG1-D at the 2019 Symposium of the Society for the Study of Inborn Errors of Metabolism (SSIEM). All patients achieved a substantial reduction in plasma arginine with the median reduction of 274 µm from baseline to 20 doses. Aeglea reported 79% (11 of 14) of patients were clinical responders, using mobility assessment components that correspond with the PEACE trial’s secondary endpoint. Pegzilarginase was well tolerated and the rates of treatment-related adverse events decreased over time.
  • Data from 10 patients dosed subcutaneously (sc) with pegzilarginase in the ongoing OLE trial for ARG1-D demonstrated that sc administration of pegzilarginase controls plasma arginine levels. All 10 patients remain on pegzilarginase sc with no patient discontinuations.
  • Mike Hanley joined Aeglea as Chief Commercial Officer in October 2019. Mr. Hanley was previously Vice President and U.S. Chief Commercial Officer for Esteve Pharmaceuticals. He also served as Group Vice President and General Manager, Orphan Business Unit for Horizon Therapeutics. Mr. Hanley has 20 years of commercial leadership experience in the life sciences industry.
  • Dr. Ravi Rao joined the Company as Chief Medical Officer in November 2019. Dr. Rao comes to Aeglea from GlaxoSmithKline, where he served as Vice President, Global Medical Affairs Head, Immunology and Specialty Franchise, leading programs across a number of emerging disease areas. Dr. Rao completed his residency training in London and is a Member of the Royal College of Physicians, London. He received his MB. BChir from Cambridge University and his Ph.D. in vascular biology from Imperial College, London in the United Kingdom and completed a postdoctoral fellowship at Harvard Medical School.

  • Jefferies 2019 London Healthcare Conference, November 20-21, London, UK

Third Quarter 2019 Financial Results

As of September 30, 2019, Aeglea had available cash, cash equivalents, marketable securities and restricted cash of $90.2 million. Based on Aeglea’s current operating plan, management believes it has sufficient capital resources to fund anticipated operations through the first quarter of 2021.

Research and development expenses totaled $17.8 million for the third quarter of 2019, compared with $8.9 million for the third quarter of 2018. The increase was primarily due to investing in manufacturing and pre-commercial activities for Aeglea’s lead product candidate, pegzilarginase, a ramp-up in toxicology, IND-enabling studies, and manufacturing activities for the Company’s AEB4104 program for homocystinuria, and expanded clinical development activity and personnel-related expenses.

General and administrative expenses totaled $4.3 million for the third quarter of 2019, compared with $3.3 million for the third quarter of 2018. This increase was primarily due to additional employee headcount, compensation, and facilities to support company growth.

Net loss totaled $21.6 million and $11.9 million for the third quarter of 2019 and 2018, respectively, with non-cash stock compensation expense of $1.4 million and $1.1 million for the third quarter of 2019 and 2018, respectively.

About Pegzilarginase in Arginase 1 Deficiency

Pegzilarginase is an enhanced human arginase that enzymatically depletes the amino acid arginine. Aeglea is developing pegzilarginase for the treatment of patients with Arginase 1 Deficiency, a rare debilitating disease presenting in childhood with persistent hyperargininemia, severe progressive neurological abnormalities and early mortality. Pegzilarginase is intended for use as an enzyme replacement therapy in patients to reduce elevated blood arginine levels. Aeglea’s Phase 1/2 and Phase 2 OLE data for pegzilarginase in patients with Arginase 1 Deficiency demonstrated clinical improvements and sustained lowering of plasma arginine. The Company’s single, global pivotal Phase 3 PEACE trial is designed to assess the effects of treatment with pegzilarginase versus placebo over 24 weeks with a primary endpoint of plasma arginine reduction.
