Second Quarter 2021 Financial Results
As of June 30, 2021, Aeglea had available cash, cash equivalents, marketable securities and restricted cash of $130.4 million inclusive of the $21.5 million upfront cash payment received from Immedica Pharma AB pursuant to the March 2021 license and supply agreement. The Company expects its cash, cash equivalents and investments will enable it to fund its operating expenses and capital expenditure requirements into 2023.
Aeglea recognized license and development revenues of $13.7 million in the second quarter of 2021, as a result of its license and supply agreement with Immedica for the commercial rights of pegzilarginase in certain territories outside the United States. The revenues recorded in the second quarter of 2021 are related to the transfer of the license and delivery of trial and regulatory services. Aeglea recognized no revenue for the corresponding period of 2020.
Research and development expenses totaled $13.6 million for the second quarter of 2021 and $16.9 million for the second quarter of 2020. The decrease was primarily associated with completing certain pre-commercial manufacturing activities for Aeglea's lead product candidate, pegzilarginase.
General and administrative expenses totaled $6.8 million for the second quarter of 2021 and $4.7 million for the second quarter of 2020. This increase was primarily due to ramping-up the Company's commercial capabilities and infrastructure.
Net loss totaled $6.8 million and $21.4 million for the second quarter of 2021 and 2020, respectively, with non-cash stock compensation expense of $2.1 million and $1.6 million for the second quarter of 2021 and 2020, respectively.
About Pegzilarginase in Arginase 1 Deficiency
Pegzilarginase is a novel recombinant human enzyme, which has been shown to rapidly and sustainably lower levels of the amino acid arginine in plasma. Aeglea is developing pegzilarginase for the treatment of patients with Arginase 1 Deficiency (ARG1-D), a rare debilitating and progressive disease characterized by the accumulation of arginine. ARG1-D presents in early childhood and patients experience spasticity, seizures, developmental delay, intellectual disability and early mortality. Aeglea's Phase 1/2 and Phase 2 open-label extension data for pegzilarginase in patients with ARG1-D demonstrated clinical improvements and sustained lowering of plasma arginine. The Company's ongoing 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. Pegzilarginase has received multiple regulatory designations, including Rare Pediatric Disease, Breakthrough, Fast Track and Orphan Drug Designations from the FDA as well as Orphan Drug Designation from the European Medicines Agency.
About AGLE-177 in Homocystinuria
AGLE-177 is a novel recombinant human enzyme, which degrades the amino acid homocysteine and its related homocystine dimer. AGLE-177 is currently being studied in a Phase 1/2 clinical trial for the treatment of patients with Classical Homocystinuria, a rare inherited disorder of methionine metabolism that results in elevated levels of homocysteine and homocystine. Homocysteine accumulation plays a key role in multiple progressive and serious disease-related complications, including thromboembolic vascular events, skeletal abnormalities (including severe osteoporosis), developmental delay, intellectual disability, lens dislocation and severe near sightedness. Preclinical data demonstrated that AGLE-177, which is designed to lower abnormally high blood levels of homocysteine, improved important disease-related abnormalities and survival in a mouse model of Homocystinuria. AGLE-177 has received both U.S. and EU Orphan Drug Designation as well as U.S. Rare Pediatric Disease Designation.
About Aeglea BioTherapeutics
Aeglea BioTherapeutics is a clinical-stage biotechnology company redefining the potential of human enzyme therapeutics to benefit people with rare metabolic diseases with limited treatment options. Aeglea's lead product candidate, pegzilarginase, is in a pivotal Phase 3 trial for the treatment of Arginase 1 Deficiency and has received both Rare Pediatric Disease and Breakthrough Therapy Designations. The Company began dosing patients in a Phase 1/2 clinical trial of AGLE-177 for the treatment of Homocystinuria in June 2021. AGLE-177 has also been granted Rare Pediatric Disease Designation. Aeglea has an active discovery platform focused on engineering small changes in human enzymes to have a big impact on the lives of patients and their families.
