On track for mid-year initiations of planned Phase 2 studies in ulcerative colitis ("UC") and rheumatoid arthritis ("RA"), providing for 7+ proof-of-concept readouts in 2026 & 2027
Reported extended follow-up Phase 1 data for SPY001, supporting that the molecule is well tolerated, has a pharmacokinetic ("PK") profile enabling quarterly or biannual dosing, and provides complete target engagement at expected Phase 2 trough concentrations
Remain on track to report interim Phase 1 data for SPY002 later this quarter, with the potential to demonstrate a product profile superior to first-generation TL1A antibodies
Announced first participant dosed in Phase 1 trial of SPY003, with interim PK and safety data readout on track for the second half of 2025

WALTHAM, Mass.,May 8, 2025/PRNewswire/ -- Spyre Therapeutics, Inc. ("Spyre" or the "Company") (NASDAQ:SYRE), a clinical-stage biotechnology company utilizing best-in-class antibody engineering, dose optimization, and rational therapeutic combinations to target improved efficacy and convenience in the treatment of inflammatory bowel disease ("IBD") and other immune-mediated diseases, today announced its first quarter 2025 financial results and provided program and corporate updates.
"We continued to efficiently execute on our ambitious strategy this quarter - presenting longer-term SPY001 Phase 1 data that further supports its potential best-in-class profile, continuing dosing with our SPY002 molecules in parallel Phase 1 trials, and initiating our fourth Phase 1 trial within nine months with SPY003," said Cameron Turtle, DPhil., Chief Executive Officer. "This quarter, we look forward to sharing interim SPY002 Phase 1 data which has the potential to demonstrate a best-in-class profile for the treatment of IBD and other immune-mediated diseases, as well as a second optimized component of our potentially paradigm-changing investigational combination therapies. Following these data, we plan to embark on two fully funded, groundbreaking Phase 2 trials that will provide 7+ proof-of-concept readouts in markets with annual revenues totaling approximately$50B. With de-risked biology, an experienced team, and a strong balance sheet, we are focused on delivering against our plans to redefine the standard-of-care in IBD and beyond while providing a transformative set of catalysts for our investors."

Development Pipeline Overview and Update

The Company's approach combines best-in-class antibody engineering, dose optimization, and rational therapeutic combinations with the goal of maximizing efficacy, safety, and convenience in the treatment of IBD and other immune-mediated diseases. IBD is a chronic condition characterized by inflammation within the gastrointestinal tract, including two main disorders: UC and Crohn's disease ("CD"). Inthe United States, it is estimated that approximately 2.4 million individuals are diagnosed with IBD. RA is a chronic inflammatory autoimmune condition that primarily affects the joints but also other parts of the body. It is characterized by pain, stiffness, and swelling of one or more joints and can progress from mild swelling of the joints in early stages to severe deformations of the feet, ankles, and hands in late/severe stages. RA affects more than 1.5 million individuals inthe United States.
The Company has three programs in clinical development, all of which are targets in IBD validated by third parties. All three validated targets offer the potential for safe and effective treatment of UC and CD, with infrequent, subcutaneous maintenance dosing as a monotherapy or in rational combinations. The Company is also planning to study its anti-TL1A program in additional indications outside IBD, beginning with RA.

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.

SPY002– a program with 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.

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.

Rational Combinations– the Company plans to investigate combinations of our proprietary antibodies in nonclinical studies and clinical trials in order to evaluate whether combination therapy can potentially lead to best-in-class efficacy in IBD, with less frequent dosing.
