WALTHAM, Mass., May 05, 2026 (GLOBE NEWSWIRE) -- Spyre Therapeutics, Inc. (“Spyre” or the “Company”) (NASDAQ:SYRE), a clinical-stage biotechnology company pioneering long-acting antibodies and antibody combinations to redefine the standard of care for inflammatory bowel disease (“IBD”) and rheumatic diseases (“RD”), today announced its first quarter 2026 financial results and provided program and corporate updates.
“With our first Phase 2 readout of the year supporting a potential best-in-class profile for SPY001 in IBD, we have begun to deliver on the promise of what we believe is one of the most ambitious and differentiated pipelines in our industry. This result opened the possibility that our monotherapies could become valuable products in IBD and further strengthened our conviction that our combination therapies have the potential to deliver paradigm-changing efficacy for the more than two million Americans suffering from IBD,” said Cameron Turtle, DPhil, Chief Executive Officer of Spyre. “We have now begun enrolling our IBD combination therapies across the world and look forward to unveiling additional monotherapy results over the next few months and combination data next year. Outside IBD, we are advancing a potentially first- and best-in-class anti-TL1A antibody across multiple rheumatic diseases, where we continue to execute ahead of schedule and see significant opportunity for this mechanism paired with a convenient dosing profile. Collectively, we believe our assets, strategy, and execution position Spyre to deliver meaningful outcomes for patients and substantial long-term value for shareholders.”
Development Pipeline Overview and Update
The Company is pioneering long-acting antibodies and antibody combinations to redefine the standard of care in IBD and rheumatic diseases. 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. RA, PsA, and axSpA are chronic inflammatory autoimmune conditions primarily characterized by pain, stiffness, and swelling of the joints, as well as impacts on the spine and skin. Together, these rheumatic conditions affect more than three million individuals in the U.S. Existing therapies for these diseases today generally offer incomplete efficacy, meaningful safety warnings, and inconvenient dosing profiles.
Each of the Company's monotherapy programs in IBD target validated mechanisms with the potential for safe and effective treatment of UC and CD with infrequent dosing as a monotherapy or in rational combinations. The Company is also studying its anti-TL1A program as a monotherapy in indications outside IBD, including RA, PsA, and axSpA.
The Company has two ongoing Phase 2 clinical trials with proof-of-concept data readouts in 2026:
SKYLINE Phase 2 Platform Trial in IBD - in May 2025, the Company initiated a Phase 2 induction and maintenance platform trial of SPY001, SPY002, SPY003, as well as pairwise combinations thereof (six investigational agents in total) in patients with moderately to severely active UC. The trial consists of two parts:
- Part A: Open-label assessment of the safety and preliminary efficacy of a single dose level of each investigational monotherapy. Enrollment for Part A has completed, with SPY001 Part A topline induction data announced in April 2026, and topline data expected for SPY002 and SPY003 in mid-2026 and the third quarter of 2026, respectively.
- Part B: Randomized and placebo-controlled assessment of the safety and efficacy of monotherapies and combinations, designed to provide dose-ranging data on monotherapies, proof-of-concept, and contribution of components for combinations, with induction data expected in 2027.
SKYLINE is currently enrolling participants into Part B of the trial.
SKYWAY Phase 2 Basket Trial in Rheumatic Diseases (RA, PsA, axSpA) - in September 2025, the Company initiated a Phase 2 randomized and placebo-controlled basket trial of SPY072 in patients with moderately to severely active RA, PsA, or axSpA. The trial consists of three sub-studies:
- RA sub-study: Double-blind, placebo-controlled safety and efficacy study of two dose levels of SPY072 at Week 12 with open-label follow-up through Week 36. This sub-study has completed enrollment ahead of schedule and topline proof-of-concept data are expected in the third quarter of 2026.
- PsA sub-study: Double-blind, placebo-controlled safety and efficacy study of a single dose level of SPY072 at Week 16 with open-label follow-up through Week 40. Enrollment continues in this sub-study and topline proof-of-concept data are expected in the fourth quarter of 2026.
-
axSpA sub-study: Double-blind, placebo-controlled safety and efficacy study of a single dose level of SPY072 at Week 16 with open-label follow-up through Week 40. Enrollment continues in this sub-study and topline proof-of-concept data are expected in the fourth quarter of 2026.
The investigational therapies being studied in the SKYLINE and SKYWAY clinical trials include:
SPY001 – a highly potent and selective investigational monoclonal antibody targeting α4β7, engineered with half-life extension technology and formulated at high concentration with the goal of maximizing efficacy and enabling infrequent, subcutaneous maintenance dosing.
- In April 2026, topline induction results were presented for SPY001 from Part A of the SKYLINE trial in ulcerative colitis subjects. 43 subjects were dosed with SPY001 and 41 subjects completed the induction period. SPY001 was well tolerated with a safety profile consistent with the α4β7 class. SPY001 achieved the primary endpoint, demonstrating a statistically significant reduction in the Robart’s Histopathology Index (RHI) score of 9.2 points (p<0.0001). The rates of key secondary endpoints of clinical remission and endoscopic improvement were clinically meaningful at 40% and 51%, respectively.
SPY002 and SPY072 – two highly potent and selective, investigational anti-TL1A monoclonal antibodies, engineered with half-life extension technology and formulated at high concentration with the goal of maximizing efficacy and enabling infrequent, subcutaneous maintenance dosing. The Company believes TL1A has emerged as one of the most promising targets in IBD and broader immunology indications. SPY002 is being evaluated for the treatment of IBD in the SKYLINE study and SPY072 is being evaluated for the treatment of rheumatic diseases in the SKYWAY study.
- In June 2025, interim healthy volunteer data from two Phase 1 trials (one for SPY002 and one for SPY072) were presented, demonstrating favorable safety profiles, meaningfully differentiated PK profiles supporting potential Q3M or Q6M maintenance dosing, and complete suppression of free TL1A through up to 20 weeks at single 100mg doses. Longer-term data from these Phase 1 trials were presented at medical meetings in late 2025, providing further support for these potential best-in-class profiles.
- Based on these interim results, SPY002 was advanced to the SKYLINE Phase 2 platform trial, and SPY072 was advanced to the SKYWAY Phase 2 basket trial.
SPY003 – a highly potent and selective investigational monoclonal antibody targeting the p19 subunit of IL-23, engineered with half-life extension technology and formulated at high concentration with the goal of maximizing efficacy and enabling infrequent, subcutaneous maintenance dosing.
- In November 2025, interim healthy volunteer data from a Phase 1 trial were disclosed, demonstrating that SPY003 exhibited a favorable safety profile and a meaningfully differentiated PK profile supporting potential Q3M or Q6M maintenance dosing. Additional data from this Phase 1 trial were presented at the 21st Congress of the European Crohn’s and Colitis Organisation ("ECCO") in February 2026, providing further support for this potential best-in-class profile.
- Based on these interim results, SPY003 was advanced to the SKYLINE Phase 2 platform trial.
Rational Combinations – the Company plans to investigate combinations of our proprietary antibodies in nonclinical studies and clinical trials in order to evaluate whether combinations can potentially lead to best-in-class efficacy in IBD, with less frequent dosing.
- In February and May 2025, preclinical data for SPY120 were presented at medical meetings, demonstrating that the combined inhibition of TL1A and α4β7 is superior to either monotherapy in mouse models of colitis and that the PK profiles of SPY001 and SPY002 were similar in non-human primates whether dosed as monotherapy or in combination, while also demonstrating no drug effects on PK.
- Preclinical data for SPY130 and SPY230 have demonstrated enhanced efficacy and pharmacodynamics with SPY003 in combination with SPY001 and with SPY002.
- The Company is enrolling each of its combinations in Part B of the SKYLINE trial.
First Quarter 2026 Financial Results
Cash Position: As of March 31, 2026, Spyre had cash, cash equivalents, and marketable securities of $741.5 million. Pro forma cash of $1,176.8 million as of March 31, 2026, also reflects $435.3 million in net proceeds from the recently closed April 2026 underwritten public offering of common stock. Net cash used in operating activities was $57.4 million for the first quarter of 2026.
Research and Development (R&D) expenses: R&D expenses totaled $60.4 million for the first quarter of 2026 and $41.6 million for the first quarter of 2025. The increase was primarily driven by higher manufacturing and clinical trial expenses, as well as higher headcount, partially offset by lower early-stage R&D activities.
General and Administrative (G&A) expenses: G&A expenses totaled $15.2 million for the first quarter of 2026 and $11.9 million for the first quarter of 2025. The increase was primarily driven by higher headcount.
Gain on Sale of In-Process Research and Development Asset: During the first quarter of 2026, the Company recognized a gain of $30.0 million for achieved milestones related to the 2023 sale of the global rights of the legacy Aeglea asset pegzilarginase to Immedica, specifically the FDA approval of pegzilarginase.
Total Other (Expense) Income: Other expense totaled $23.4 million for the first quarter of 2026 compared to $8.8 million of other income in the first quarter of 2025, primarily driven by changes in the fair value of the contingent value right (CVR) liability.
Net Loss: Net loss totaled $69.0 million and $44.8 million for the first quarters of 2026 and 2025, respectively.
