Insights

Spyre Therapeutics is making significant strides in developing potentially best-in-class antibodies for inflammatory bowel disease (IBD) treatment. The acceleration of SPY003 (IL-23p19) clinical timelines is particularly noteworthy, with first-in-human dosing now expected in Q1 2025. This puts Spyre on a faster track to potentially disrupt the IBD treatment landscape.

Key highlights:

  • SPY003 shows comparable potency to risankizumab with a 300% longer half-life in non-human primates, potentially enabling quarterly or bi-annual dosing.
  • Spyre's portfolio now includes extended half-life molecules targeting α4β7, TL1A and IL-23, positioning them uniquely in the market for combination therapies.
  • Preclinical data on SPY003 in combination with SPY001 or SPY002 demonstrated enhanced efficacy, suggesting potential for superior treatment options.
  • The company expects to share interim data from the SPY003 first-in-human trial in H2 2025, which could be a significant catalyst for investor interest.

While still in early stages, Spyre's approach of combining best-in-class antibody engineering with rational therapeutic combinations could lead to improved efficacy and convenience in IBD treatment. This potential for differentiation in a competitive market makes Spyre an interesting player to watch in the biotech space.

The preclinical data presented by Spyre Therapeutics at UEGW is promising and supports their strategy of developing extended half-life antibodies for IBD treatment. The combination therapy approach, particularly the synergistic effects observed with anti-IL-23 and anti-TL1A, is scientifically intriguing and aligns with the current trend towards more targeted, personalized treatments in gastroenterology.

Key scientific insights:

  • SPY003's 30-day half-life in non-human primates could translate to significantly improved patient compliance and quality of life if replicated in humans.
  • The synergistic suppression of IL-17 secretion by anti-IL-23 and anti-TL1A combination suggests a potential for enhanced efficacy in controlling inflammation.
  • In vivo models showing improved body weight and reduced colonic CD4+ infiltration with combination therapy provide a strong rationale for further clinical investigation.

While these results are encouraging, it's important to remember that preclinical success doesn't always translate to clinical efficacy. The upcoming first-in-human trials, particularly for SPY003 and the SPY002 candidates, will be critical in validating these findings and determining the true potential of Spyre's approach in IBD treatment.

SPY003, a novel half-life extended IL-23p19 monoclonal antibody (mAb), with first-in-human dosing now expected first quarter 2025

New data on SPY003 presented at UEGW demonstrating robust preclinical activity including comparable potency and a greater than three-fold extension in half-life in NHPs relative to risankizumab1. Spyre portfolio now uniquely includes extended half-life molecules targeting α4β7, TL1A, and IL-23 with potential Q8W-Q12W maintenance dosing.

Additional preclinical data on SPY003 in combination with SPY001 or SPY002 presented at UEGW showing enhanced preclinical efficacy and pharmacodynamics

WALTHAM, Mass., Oct. 14, 2024 /PRNewswire/ -- Spyre Therapeutics, Inc. (NASDAQ: SYRE) (the "Company" or "Spyre"), a clinical-stage biotechnology company utilizing best-in-class antibody engineering, rational therapeutic combinations, and precision medicine approaches to target improved efficacy and convenience in the treatment of inflammatory bowel disease ("IBD"), today announced updated pipeline progress and timelines, as well as scientific presentations at the United European Gastroenterology Week ("UEGW") Congress.

  • First-in-human dosing of SPY003 (anti-IL-23) in healthy volunteers is now expected to start during the first quarter of 2025. SPY003 is a novel, half-life extended mAb targeting IL-23p19 ("IL-23"). Approved inhibitors of IL-23 are effective and well tolerated treatments of moderate-to-severe IBD, with commercially available therapies dosed six times per year. SPY003 has the potential to be dosed quarterly or twice a year as a monotherapy in maintenance. The company expects to share interim data from the accelerated first-in-human trial in the second half of 2025.

  • Spyre presented preclinical data on SPY003 for the first time at UEGW, expanding its portfolio of half-life extended antibodies to three validated targets in IBD. The presentation illustrated in vitro potency comparable to risankizumab1 and pharmacokinetics indicating that SPY003 has a half-life of ~30 days in non-human primates ("NHPs"), a greater than three-fold increase relative to risankizumab1. These data demonstrate that SPY003 exhibits high selectivity and affinity for IL-23 and potently inhibits downstream cellular signaling. With an extended half-life in NHPs, SPY003 demonstrates therapeutic potential for effective and well-tolerated treatment of Crohn's disease ("CD") and Ulcerative Colitis ("UC") with less frequent dosing than approved therapies. In conjunction with its previously disclosed SPY001 (anti-α4β7) and SPY002 (anti-TL1A) programs, the company has a unique portfolio of antibodies that have the potential to be delivered in combination on a unified, Q8W-Q12W dosing frequency in maintenance.

  • Spyre presented preclinical data combining anti-IL-23 with either anti-α4β7 or anti-TL1A for the first time at UEGW. The presentation included in vitro studies and in vivo murine colitis model on anti-IL-23 combined with anti-TL1A and anti-α4β7, respectively. The models showed that IL-23 and TL1A have a synergistic effect on promoting IL-17 secretion from human and mouse immune cells, and that the combination of anti-IL-23 and anti-TL1A suppresses IL-17 secretion more effectively than either agent alone. In a T-cell transfer model of IBD, combination therapy with anti-IL-23 and anti-β7 improved body weight and reduced colonic CD4+ infiltration and IL-17 levels relative to monotherapy.

  • Additional preclinical data for SPY001 (anti-α4β7) and SPY002 (anti-TL1A) presented at UEGW. These presentations included in vitro potency compared to benchmark antibodies, nonclinical safety data, and pharmacokinetics demonstrating extended half-life in NHPs. For SPY002, characterization of the two development candidates planned for first-in-human studies in Q4 2024 is further described. Human pharmacokinetic simulations for SPY001 and both SPY002 candidates support potential Q8-12W dosing regimens in IBD.

"The Spyre team has made significant progress in advancing its potentially best-in-class molecules into first-in-human studies within an expected nine-month window," said Cameron Turtle, DPhil, chief executive officer of Spyre. "With these promising molecules against the top three validated targets in IBD, we believe that Spyre is uniquely positioned to develop monotherapy and combination products with the potential to meaningfully improve both efficacy and convenience compared to today's standard of care."

The posters were presented at the UEGW Congress on Saturday, October 12, 2024, and details are as follows:

Title: A Novel Monoclonal Antibody Drug Candidate SPY001 Targeting Integrin ɑ4β7 for the Treatment of IBD: In Vitro Properties and Non-Human Primate Pharmacokinetics and Safety
