Aeglea BioTherapeutics Reports First Quarter 2022 Financial Results and Provides Program Updates

 

Pegzilarginase BLA submitted to the FDA; if approved, pegzilarginase would be the first FDA-approved treatment for Arginase 1 Deficiency

 

Additional PEACE data supporting potential efficacy of pegzilarginase presented at SIMD

 

Enrollment continues in Phase 1/2 trial of AGLE-177; IND now open for U.S. site initiation

 

 

Austin, Texas, May 5, 2022 - 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 announced financial results for the first quarter 2022 and provided program updates.

 

“We have started off 2022 with significant progress in both our clinical programs. With AGLE-177, we were pleased to see total homocysteine lowering in all patients in our first, low dose cohort and we look forward to sharing clinical data later this year. This program is another example of innovation with human enzyme therapies and has the potential to address a significant unmet need,” said Anthony Quinn, M.B., Ch.B., Ph. D., president and chief executive officer of Aeglea. “I’m also proud of the work we have done with our pegzilarginase program enabling our recent BLA submission to the FDA with what we believe are very compelling data to support approval for the treatment of Arginase 1 Deficiency. Some of these data were presented recently at the SIMD Annual Meeting, providing additional insight into the potential positive impact of pegzilarginase treatment. We look forward to working with the FDA throughout the review of our BLA as they assess the potential effectiveness of pegzilarginase in addressing the unmet need that impacts the lives of Arginase 1 Deficiency patients and their families.”

 

Program Updates

 

Pegzilarginase in Arginase 1 Deficiency

 

Submitted a Biologics License Application (BLA) to the U.S. Food and Drug Administration (FDA) for pegzilarginase for the treatment of Arginase 1 Deficiency (ARG1-D).

 

o

Requested Priority Review at the time of submission.

 

Presented new data from the PEACE Phase 3 clinical trial at the Society for Inherited Metabolic Disorders (SIMD) Annual Meeting, including patient-level outcomes, results from additional secondary endpoints and previously announced topline results. Highlights of the data presented include:

 

o

76.7% reduction in mean plasma arginine in pegzilarginase treated patients compared to placebo (p<0.0001); normal plasma arginine levels achieved in 90.5% of pegzilarginase treated patients compared to no patients receiving placebo.

 

o

Eleven patients (65%) treated with pegzilarginase reached or exceeded response criteria for ≥1 mobility assessment compared to four patients (44%) receiving placebo.

 

o

Eight patients (47%) treated with pegzilarginase met or exceeded prespecified clinical response criteria for ≥2 mobility assessments compared to no patients receiving placebo.

 


 

 

o

In a post hoc analysis correcting for a missed assessment that was improperly scored as 0 rather than “not assessed, the least squares mean Gross Motor Function Measure Part D score of patients treated with pegzilarginase improved from baseline by 2.25 units compared to placebo (p=0.0896).

 

o

Pegzilarginase treated patients showed statistically significant biochemical improvements in measures of ornithine and guanidino compounds compared to placebo.

 

On track to submit a Marketing Authorization Application (MAA) to the European Medicines Agency (EMA) in 2022.

 

AGLE-177 in Homocystinuria

 

Working to initiate U.S. sites to support enrollment in the ongoing Phase 1/2 clinical trial and a potential pivotal Phase 3 trial after opening an Investigational New Drug (IND) application with the FDA.

 

Expect to announce Phase 1/2 clinical data in the second half of 2022.

 

First Quarter 2022 Financial Results

 

As of March 31, 2022, Aeglea had available cash, cash equivalents, marketable securities and restricted cash of $68.6 million. The Company expects its cash, cash equivalents and investments will enable it to fund its operating expenses and capital expenditure requirements into the first quarter of 2023.

 

Aeglea recognized development fee revenues of $1.4 million in the first quarter of 2022, as a result of its license and supply agreement with Immedica for the commercial rights to pegzilarginase in certain territories outside the U.S. The revenues recorded in the first quarter of 2022 are related to the PEACE Phase 3 trial and BLA package. Aeglea recognized no revenue for the first quarter of 2021.

 

Research and development expenses totaled $17.0 million for the first quarter of 2022 and $11.9 million for the first quarter of 2021. The increase was primarily associated with expenses related to the BLA submission, management and dosing of ongoing patients in the PEACE Phase 3 trial, and increased enrollment in our Phase 1/2 trial of AGLE-177 for the treatment of patients with Homocystinuria.  

 

General and administrative expenses totaled $8.8 million for the first quarter of 2022 and $6.4 million for the first quarter of 2021. This increase was primarily due to ramping-up the Company’s commercial capabilities and infrastructure as well as personnel expenses.

 

Net loss totaled $24.4 million and $18.2 million for the first quarter of 2022 and 2021, respectively, with non-cash stock compensation expense of $2.1 million and $1.8 million for the first quarter of 2022 and 2021, respectively.

 

About Pegzilarginase in Arginase 1 Deficiency

Pegzilarginase is a novel recombinant human enzyme engineered to degrade the amino acid arginine and has been shown to rapidly and sustainably lower levels of the amino acid arginine in plasma. Aeglea is developing pegzilarginase for the treatment of people 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.

The PEACE Phase 3 clinical trial met its primary endpoint with a 76.7% reduction in mean plasma arginine compared to placebo. Additionally, 90.5% of pegzilarginase treated patients achieved normal plasma arginine levels. The arginine lowering was accompanied by a positive trend in Gross Motor Function Measure Part E, a measure of patient mobility. Aeglea’s Phase 1/2 and Phase 2 Open-Label Extension (OLE) data for pegzilarginase in patients with ARG1-D demonstrated clinical improvements and sustained lowering of plasma arginine. Pegzilarginase has received multiple regulatory designations, including Rare Pediatric Disease, Breakthrough Therapy, Fast Track and Orphan Drug designations from the U.S. Food and Drug Administration 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 is engineered to degrade the amino acid homocysteine and its dimer, homocystine. 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 total homocysteine. 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 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. In April 2022, Aeglea announced it had submitted a Biologics License Application to the FDA for its lead product candidate, pegzilarginase, in patients with Arginase 1 Deficiency. Pegzilarginase achieved the primary endpoint of arginine reduction in the PEACE Phase 3 clinical trial and has received both Rare Pediatric Disease and Breakthrough Therapy Designations. Aeglea also has an ongoing Phase 1/2 clinical trial of AGLE-177 for the treatment of Homocystinuria. AGLE-177 has 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.
