56 Week Analysis of Phase 1/2 Open-Label Extension Study


Initiated Phase 1/2 Clinical Trial of ACN00177 for the Treatment of Homocystinuria

Austin, Texas, August 10, 2020 -

Aeglea BioTherapeutics, Inc. (NASDAQ:AGLE), a clinical-stage biotechnology company developing a new generation of human enzyme therapeutics as innovative solutions for rare and other high-burden diseases, today reported its second quarter 2020 financial results, and provided recent corporate and program highlights.


“Despite the operating challenges posed by the global pandemic, we continued to advance our pegzilarginase program in the first half of the year. The presentation of long-term data showing sustained lowering of arginine levels and durable clinical response with pegzilarginase treatment, as well as progress in our patient identification efforts, reinforce our belief in its potential as a life-changing therapy for those with Arginase 1 Deficiency and lay a strong foundation for the commercial launch of pegzilarginase,” said Anthony Quinn, M.B Ch.B, Ph.D., president and chief executive officer of Aeglea. “Additionally, we initiated our Phase 1/2 clinical trial of ACN00177 for Homocystinuria in the second quarter. We are continuing our patient identification activities and look forward to dosing the first patient once the clinical sites are able to begin screening patients.”

Recent Highlights and Updates

Pegzilarginase in Arginase 1 Deficiency


In May, Aeglea presented results from its 56 week analysis from the Company’s completed Phase 1/2 clinical trial and ongoing open-label extension study during a late-breaking oral presentation at the 6th Congress of the European Academy of Neurology. Key results include:



Treatment with pegzilarginase resulted in a significant reduction in plasma arginine from baseline with all 13 patients achieving plasma arginine levels within the target range (<200 µM).



85% (11 of 13) of patients were clinical responders based on mobility improvements evaluated using three assessments: 6MWT (6 Minute Walk Test), GMFM (Gross Motor Function) Part D (standing) and Part E (walking, running, and jumping).



Pegzilarginase was shown to have a favorable safety profile with more than 750 doses administered.


To date, Aeglea has identified more than 240 Arginase 1 Deficiency patients. The number of identified patients represents more than 50% and 30% of the estimated genetic prevalence patient population in the U.S. and key European markets (France, Germany, Spain, Italy and the United Kingdom), respectively.


ACN00177 in Homocystinuria


Aeglea initiated its Phase 1/2 clinical trial for ACN00177, a novel engineered human enzyme therapy designed to treat Homocystinuria, a serious metabolic disorder characterized by elevated plasma homocysteine which leads to a wide range of life-altering complications and reduced life expectancy.




Eric Bradford, M.D., M.Sc., M.B.A. has been promoted to Chief Development Officer. Dr. Bradford will oversee the clinical programs for pegzilarginase and ACN00177 as well as shape the clinical development strategy for future programs from the Company’s platform of novel human enzymes.


Chief Medical Officer Ravi M. Rao, M.B BChir, Ph.D., will depart the company to pursue other opportunities. Dr. Rao will continue to support Aeglea in a medical advisor role through a transitional period.


“Ravi has been a valued and impactful member of the Aeglea team. While we are disappointed by his planned departure, we wish him the best as he returns to his roots in immunology research and development,” said Dr. Quinn. “I look forward to working more closely with Eric as we continue to strengthen our capabilities and advance pegzilarginase towards potential approval and launch.”
