Spyre Therapeutics, Inc. (NASDAQ:SYRE) (the "Company" or "Spyre"), a development-stage biotechnology company advancing best-in-class antibody engineering, rational therapeutic combinations, and precision medicine approaches for the treatment of Inflammatory Bowel Disease ("IBD"), today announced three abstracts co-written with Spyre's research partner, Paragon Therapeutics, Inc., highlighting that the Company's co-lead product candidates, SPY001 and SPY002, have been accepted for presentation as posters at the upcoming 19th Annual Congress of the European Crohn's and Colitis Organisation (ECCO), held February 21-24, 2024, in Stockholm, Sweden. SPY001 is a fully optimized and half-life extended antibody targeting α4β7 and SPY002 is a fully optimized and half-life extended antibody targeting TL1A, both in development for the treatment of IBD.
"We are thrilled to share preclinical findings supporting our two lead programs, SPY001 and SPY002, during the ECCO Congress," said Joshua Friedman, MD, PhD, SVP of Clinical Development of Spyre. "The preclinical potency, selectivity, and drug-like properties of these investigational antibodies match our ideal product profiles. Further, the half-life extension observed in animal studies supports the potential for human dosing every other month or quarterly, which, if supported by clinical trial results, would be a significant improvement compared to today's approved therapies. We are eager to initiate Phase 1 clinical studies in each program this year."
The posters will be available for viewing during the ECCO Congress beginning on Friday, February 23, 2024, and details are as follows:
