Austin, Texas, March 18, 2021 -

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


“2020 was a challenging year advancing our clinical trials and at the same time prioritizing the health and well-being of the rare disease patients we serve, who often have additional difficulties and vulnerabilities,” said Anthony Quinn, M.B Ch.B, Ph.D., president and chief executive officer of Aeglea. “We have been focused on mitigating the impact of COVID-19 on our clinical timelines and I’m proud of the work the team has done to put patient needs first while also advancing a broad range of other impactful activities, as seen with the regulatory designations received for AGLE-177, our continuous gains in Arginase 1 Deficiency patient identification and the buildout of our commercial organization.”


Dr. Quinn continued, “With enrollment completion expected this month and data expected in the fourth quarter for our pivotal Phase 3 PEACE study of pegzilarginase in Arginase 1 Deficiency, and the potential for first-in-human data from our AGLE-177 Phase 1/2 clinical trial in Homocystinuria, 2021 is shaping up to be a transformational year and we are well positioned to evolve into a successful commercial-stage company.”


Recent Highlights and Updates

Pegzilarginase in Arginase 1 Deficiency



As of mid-March, 24 patients have been enrolled and randomized in the pivotal Phase 3 PEACE clinical trial. An additional nine patients are in active screening or scheduled to begin screening in the next two weeks. Trial enrollment is expected to close in March, with completion of screening and all patients randomized by the end of April. Topline data is expected in the fourth quarter of 2021.


As of January, Aeglea has identified over 300 Arginase 1 Deficiency patients in addressable markets. The number of currently identified patients represents approximately 65% and 30% of the estimated genetic prevalence populations in the U.S. and EU4 plus the UK, respectively.


At the 2021 JP Morgan Healthcare Conference, Aeglea provided an update on the safety profile of pegzilarginase. As of September 2020, more than 1,350 doses had been administered in the Phase 1/2 clinical trial and Phase 2 open-label extension study.


AGLE-177 in Homocystinuria



In December 2020, Aeglea announced the U.S. Food and Drug Administration (FDA) granted Rare Pediatric Disease Designation to AGLE-177 for the treatment of Homocystinuria. If AGLE-177 is approved by the FDA, the company will be eligible to receive a Priority Review Voucher.


In January, Aeglea announced it will be adding clinical trial sites in Australia for its Phase 1/2 clinical trial.


In January, the Company presented the results of an analysis which determined the Classical Homocystinuria (CBS deficiency) population in global addressable markets may exceed 30,000 patients, with an estimated 15,000-18,000 of those patients to be non-responsive to the existing standard of care.




Aeglea expanded the Company’s Board of Directors to include two new members. Alison Lawton, who previously served as president and CEO of Kaleido Biosciences, was appointed in December 2020. Sara Brownstein, a principal at Baker Bros. Advisors LP, was appointed in February 2021.
