WALTHAM, Mass., Aug. 04, 2026 (GLOBE NEWSWIRE) -- Spyre Therapeutics, Inc. (“Spyre” or the “Company”) (NASDAQ:SYRE), a clinical-stage biotechnology company committed to developing next-generation therapies that elevate the standard in immunology by delivering more complete disease control, greater durability, and a simpler treatment experience for patients, today announced its second quarter 2026 financial results and provided program and corporate updates.
“Following encouraging Phase 2 results from both SPY001 and SPY002, as well as competitor results validating the promise of combination therapy, the case for our approach in IBD has strengthened considerably. We believe our three investigational combinations have the potential to deliver efficacy, safety, and convenience beyond what is achievable with today’s therapies,” said Cameron Turtle, DPhil, Chief Executive Officer of Spyre. “Beyond IBD, we are approaching a pivotal milestone with placebo-controlled Phase 2 proof-of-concept data for SPY072, an anti-TL1A monotherapy, in rheumatoid arthritis expected next month, representing a key opportunity to demonstrate the broader utility of this mechanism. If successful, we look forward to initiating pivotal development of SPY072 next year, while also exploring combination approaches outside IBD.”
Development Pipeline Overview and Update
The Company is developing next-generation therapies that elevate the standard in immunology, with an initial focus in inflammatory bowel disease (“IBD”) and rheumatic diseases, including RA, PsA, and axSpA. 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 United States. Existing therapies for these diseases today generally offer incomplete efficacy, meaningful safety warnings, and inconvenient dosing pro
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 and 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 and SPY002 Part A topline induction data announced in Q2 2026, and topline data expected for SPY003 in September 2026.
Topline induction data from Part A of the SKYLINE trial in UC subjects were presented in April 2026 and June 2026 for SPY001 and SPY002, respectively. SPY001 and SPY002 were well-tolerated with a safety pro with in-class comparators. SPY001 and SPY002 achieved their respective primary endpoints, demonstrating statistically significant reductions in the Robart’s Histopathology Index score of 9.2 points and 10.7 points, respectively. Rates of key secondary endpoints of clinical remission and endoscopic improvement were robust and clinically meaningful at 40% and 51%, respectively, for SPY001 and 33% and 42%, respectively, for SPY002. The change in the modified Mayo Score from baseline at Week 12 for both SPY001 and SPY002 was -3.7, reflecting consistency across secondary endpoints.
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, and 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, all of which have completed enrollment on or ahead of schedule:
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. Topline proof-of-concept data are expected in September 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. 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. 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. SPY001 is being evaluated for the treatment of IBD in the SKYLINE study.
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.
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. SPY003 is being evaluated for the treatment of IBD in the SKYLINE study.
Rational Combinations [SPY120, SPY130 and SPY230]
– the Company is investigating combinations of our proprietary antibodies in clinical trials in order to evaluate whether combinations can potentially lead to best-in-class efficacy in IBD, with less frequent dosing.
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 pharmacokinetic profiles of SPY001 and SPY002 were similar in non-human primates whether dosed as monotherapies or in combination.
Preclinical data for SPY130 and SPY230 have also demonstrated enhanced efficacy and pharmacodynamics with SPY003 in combination with SPY001 and SPY002.
The Company is enrolling each of its combinations in Part B of the SKYLINE trial.
