“This year is a pivotal period for Spyre as we begin to unveil results from our two groundbreaking Phase 2 trials with the potential to identify multiple products that leapfrog today's standard of care and provide substantially improved therapies for patients suffering from severe autoimmune diseases. In IBD, we plan to reveal initial safety and efficacy data for our optimized antibodies against the most compelling targets in the space. If successful, these results would support our view that our antibodies are the ideal components for combination therapies with the potential to transform the treatment paradigm in this disease,” said
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
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 beginning in 2026:
SKYLINE Phase 2 Platform Trial in IBD - in
- Part A: Open-label assessment of the safety and preliminary efficacy of a single dose level of each investigational monotherapy, with induction data expected beginning in the second quarter of 2026.
- Part B: Randomized and placebo-controlled assessment of the safety and efficacy of investigational monotherapies (two dose levels) and combinations, with induction data expected in 2027.
SKYLINE is currently enrolling subjects into Part A of the trial, with Part B expected to begin enrolling after all arms in Part A complete enrollment.
SKYWAY Phase 2 Basket Trial in Rheumatic Diseases (RA, PsA, axSpA) - in
- RA sub-study: Double-blind, placebo-controlled safety and efficacy study of two dose levels of SPY072 at Week 12.
- PsA sub-study: Double-blind, placebo-controlled safety and efficacy study of a single dose level of SPY072 at Week 16.
- axSpA sub-study: Double-blind, placebo-controlled safety and efficacy study of a single dose level of SPY072 at Week 16.
The investigational therapies being studied in the SKYLINE and SKYWAY clinical trials include:
SPY001 – a highly potent and selective investigational monoclonal antibody targeting a4ß7, engineered with half-life extension technology and formulated at high concentration with the goal of maximizing efficacy and enabling infrequent, subcutaneous maintenance dosing.
- In
May 2025 , extended follow up data were presented at Digestive Disease Week ("DDW") 2025 from the Phase 1 healthy volunteer trial, demonstrating a favorable safety profile across all dose groups, a meaningfully differentiated pharmacokinetic ("PK") profile supporting potential Q3M or Q6M maintenance dosing, and rapid and complete saturation of a4ß7 receptors beyond six months with a single dose of 600mg. - Based on these interim results, SPY001 was advanced into the SKYLINE Phase 2 platform trial.
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 21stCongress of the European Crohn’s andColitis Organisation ("ECCO") inFebruary 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 a4ß7 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 expects to include each of its rational combinations in Part B of the SKYLINE trial.
