WALTHAM, Mass., Nov. 9, 2023 /PRNewswire/ — Aeglea BioTherapeutics, Inc. (“Aeglea” or the “Company”) (NASDAQ:AGLE), a biotechnology company advancing a pipeline of antibody therapeutics with the potential to transform the treatment of inflammatory bowel disease (“IBD”), today announced its third quarter 2023 financial results and provided program and corporate updates.

“We have made significant progress in our first quarter following the Spyre acquisition towards our goal of creating new, best-in-class medicines for patients with IBD. We believe that our combination strategy and pipeline, including SPY001, an extended half-life anti-α4β7 antibody, and SPY002 a dual monomer / trimer anti-TL1A antibody with picomolar affinity and extended half-life, offer the potential to meaningfully improve both efficacy and convenience relative to today’s standard of care,” said Cameron Turtle, D.Phil., Chief Operating Officer of Aeglea. “In addition to progressing our portfolio towards first-in-human studies next year, we have built out our team with passionate and experienced biotechnology leaders.” 

Development Pipeline Overview and Update

With its acquisition of Spyre Therapeutics, Inc. (“Spyre”) in June 2023, Aeglea shifted its disease focus to IBD. The Company’s approach combines best-in-class antibody engineering, rational therapeutic combinations, and precision immunology with the goal of maximizing efficacy, safety, and convenience of its IBD treatments under development.  IBD is a chronic condition characterized by inflammation within the gastrointestinal tract, including two main disorders: ulcerative colitis (“UC”) and Crohn’s disease (“CD”).  In the United States, it is estimated that approximately 2.4 million individuals are diagnosed with IBD.

The Company has four product candidates in preclinical development, three of which are validated targets in IBD.  The fourth product candidate is a novel, undisclosed target.

SPY001 – a highly potent and selective anti-α4β7 monoclonal antibody engineered with half-life extension technology and formulated for high concentration, convenient dosing.

• SPY001 is currently progressing through IND-enabling studies and is expected to enter first-in-human (“FIH”) studies in the first half of 2024.
• Interim data from a healthy volunteer study are expected by the end of 2024. The Company expects pharmacokinetic data to demonstrate proof of concept for its ability to potentially reach an every-eight-week or every-twelve-week dosing interval.

SPY002 – a highly potent and selective anti-TL1A monoclonal antibody engineered with half-life extension technology. The Company believes TL1A has emerged as one of the most promising targets in IBD and broader immunology indications.

• The Company’s extensive discovery campaign has identified lead clones which bind both TL1A monomers and trimers with picomolar affinity and have in vitro potency and pharmacokinetic half-lives that exceed all clinical-stage TL1A antibodies.
• The Company expects to begin FIH studies of the SPY002 program in the second half of 2024 with healthy volunteer interim data expected in the first half of 2025.

SPY003 – a highly potent and selective monoclonal antibody targeting the p19 subunit of IL-23 engineered with half-life extension technology.

• The Company continues preclinical development efforts on a potential best-in-class IL-23 monoclonal antibody. Recent data from the Phase 3 SEQUENCE study of risankizumab versus ustekinumab in Crohn’s disease validates the Company’s targeting of the p19 subunit as it demonstrated superiority to targeting the p40 subunit of IL-23.
• An IND/CTN is expected in 2025.

Corporate Updates 

• In October 2023, the Company filed a definitive proxy statement regarding the Special Meeting of Stockholders to be held on November 21, 2023 (the “Special Meeting”). At the Special Meeting, stockholders are expected to vote on four proposals, including the conversion of the Company’s Series A Preferred Stock to common stock and an increase to the Company’s authorized shares.
• In September 2023, the Company strengthened its leadership team with the appointments of industry veterans Scott Burrows, as Chief Financial Officer, and Heidy Abreu King-Jones, as Chief Legal Officer and Corporate Secretary.
• In September 2023, the Company completed a reverse stock split of all outstanding shares of common stock at a ratio of 1-for-25, with trading on a split-adjusted basis on the Nasdaq Capital Market beginning on September 8, 2023.
• In July 2023, the Company sold the global rights to pegzilarginase to Immedica Pharma AB (“Immedica”) for $15 million in upfront cash proceeds and up to $100 million in contingent milestone payments. In November 2023, holders of the Company’s contingent value rights (CVRs) are expected to receive a payment representing the Immedica sale proceeds net of expenses and adjustments pursuant to the CVR agreement entered into in connection with Aeglea’s acquisition of Spyre.

Third Quarter 2023 Financial Results

Cash Position: As of September 30, 2023, Aeglea had available cash and cash equivalents, marketable securities, and restricted cash of $204.9 million.

Research and Development (R&D) expenses: R&D expenses totaled $24.7 million for the third quarter of 2023 and $12.0 million for the third quarter of 2022. This increase was primarily related to increases in preclinical development and manufacturing expenses for the Company’s IBD pipeline, partially offset by a decrease in expenses associated with the legacy Aeglea rare disease pipeline.

General and Administrative (G&A) expenses: G&A expenses totaled $8.6 million for the third quarter of 2023 and $7.0 million for the third quarter of 2022. This increase was primarily due to an increase in legal and employee separation costs.

Gain on Sale of In-Process Research & Development Asset:  During the third quarter of 2023, the Company recognized a $14.6 million gain on the sale of the global rights of pegzilarginase to Immedica.

Other Income and Expenses: Other Income and Expenses were a net $21.8 million expense in the third quarter of 2023, primarily driven by a $25.4 million non-cash forward contract liability expense related to an increase in fair value of the underlying Series A Preferred Stock between June 30, 2023 and the forward contract’s settlement on July 7, 2023.

Net Loss: Net loss totaled $40.1 million and $18.2 million for the third quarter of 2023 and 2022, respectively, which includes non-cash stock compensation expense of $4.8 million and $1.6 million for the third quarter of 2023 and 2022, respectively.
