Spyre Therapeutics Announces Poster Presentation at the 20th Congress of the European Crohn's and Colitis Organisation

, /PRNewswire/ -- Spyre Therapeutics, Inc. (NASDAQ: SYRE) (the "Company" or "Spyre"), a clinical-stage biotechnology company advancing best-in-class antibody engineering, dose optimization, and rational therapeutic combinations for the treatment of Inflammatory Bowel Disease ("IBD") and other immune-mediated diseases, today announced a poster presentation at the 20th Congress of the European Crohn's and Colitis Organisation (ECCO), held February 19-22, 2025, in Berlin, Germany, showing that combined inhibition of α4β7 integrin and TL1A cytokine is superior to either monotherapy in mouse models of colitis and coadministration demonstrates no drug-drug effects on exposure in non-human primates (NHPs). "We are thrilled to share these recent preclinical findings supporting the combination potential for our SPY120 program (anti-α4β7 and anti-TL1A). We tested mouse surrogates of SPY120 in two in vivo models of IBD, demonstrating that combined inhibition of the α4β7 integrin and TL1A cytokine provide additive or greater than additive efficacy relative to inhibition of either target alone," said Andy Spencer, PhD, SVP of Preclinical R&D at Spyre. "Further, the pharmacokinetic profiles of our SPY001 and SPY002 antibodies in NHPs were similar when dosed as monotherapies or in combination, indicating the potential for quarterly or twice-annual dosing of SPY120 in humans. Together, these results demonstrate the potential for SPY120 to have best-in-indication efficacy and convenience in IBD, complementing our previously disclosed preclinical results for SPY130 (anti-α4β7 and anti-IL-23) and SPY230 (anti-TL1A and anti-IL-23). We look forward to testing all three potential best-in-indication combinations in our Phase 2 trial in ulcerative colitis patients which is expected to begin mid-year." The poster will be available for viewing during the ECCO Congress beginning on February 19, 2025, and details are as follows: Title: Combined inhibition of TL1A and integrin β7 is superior to either monotherapy in mouse models of colitis and coadministration of SPY001 and SPY002 demonstrates no drug-drug effects on exposure in non-human primatesAuthors: M Siegel, J Friedman, D Nguyen, J McNally, M Kennedy, O Ballew, M Rose, A Spencer Full session details can be accessed via the ECCO program.
