Aeglea BioTherapeutics Reports First Quarter 2023 Financial Results

$39.8 million of cash and cash equivalents, marketable securities, and restricted cash as of March 31, 2023

Austin, Texas, May 11, 2023 - Aeglea BioTherapeutics, Inc. (NASDAQ:AGLE) today announced financial results for the first quarter 2023.

First Quarter 2023 Financial Results

As of March 31, 2023, Aeglea had available cash and cash equivalents, marketable securities and restricted cash of $39.8 million.

Aeglea recognized development fee and royalty revenues of $0.2 million in the first quarter of 2023, as a result of its license and supply agreement with Immedica Pharma AB for the commercial rights to pegzilarginase in Europe and several countries in the Middle East (License and Supply Agreement). The revenues recorded in the first quarter of 2023 are related to the PEACE Phase 3 trial and royalties from an early access program in France. Aeglea recognized $1.4 million for the first quarter of 2022 in development fee revenues.

Research and development expenses totaled $13.8 million for the first quarter of 2023 and $17.0 million for the first quarter of 2022. The decrease was primarily related to a decrease in activities related to the PEACE Phase 3 trial and Biologics License Application for pegzilarginase.

General and administrative expenses totaled $5.2 million for the first quarter of 2023 and $8.8 million for the first quarter of 2022. This decrease was primarily due to a reduction in headcount and related expenses and decrease in commercialization activities for pegzilarginase.

Net loss totaled $18.4 million and $24.4 million for the first quarter of 2023 and 2022, respectively, which includes non-cash stock compensation expense of $1.7 million and $2.1 million for the first quarter of 2023 and 2022, respectively.
