(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 positive interim Phase 1 data from its first-in-human trial of SPY001, an investigational novel, extended half-life monoclonal antibody targeting α4β7. SPY001 was well tolerated with pharmacokinetic (\"PK\") data demonstrating a half-life of >90 days and pharmacodynamic (\"PD\") data demonstrating complete target engagement at all time points available.\nInterim results from the trial, with data as of October 30, 2024, exceeded the Company's expectations and support the potential for SPY001 to become a next-generation anti-α4β7 therapy and backbone for paradigm-changing combination therapies in IBD. The PK and PD results support optimized Phase 2 dosing including (i) increased induction exposures with the potential to improve or accelerate efficacy compared to other anti-α4β7 treatments and (ii) maintenance dosing on a potential Q3M and Q6M frequency via a single subcutaneous injection. Across single doses of up to 1000 mg and multiple doses of up to 600 mg, SPY001 was well-tolerated with no serious adverse events reported and all adverse events being mild in severity. Based on these data, and subject to regulatory feedback, the Company plans to initiate a Phase 2 platform trial in mid-2025 that will ultimately include SPY001, SPY002 (TL1A), SPY003 (IL-23) and combinations thereof, providing three optimized monotherapy readouts and three potentially paradigm-changing combination readouts under an efficient single master protocol.\n\"These interim data exceeded our expectations for SPY001 and support its potential to become both a differentiated monotherapy and an ideal backbone for combination therapy in IBD,\" said Cameron Turtle, DPhil, Chief Executive Officer of Spyre. \"We look forward to initiating Phase 2 trials next year that explore SPY001's safety and efficacy in IBD patients. Alongside our half-life-extended antibodies targeting TL1A and IL-23, we believe the Spyre portfolio is uniquely positioned to develop products that could substantially improve upon today's standard of care in IBD.\"\nKey SPY001 Phase 1 Interim Findings\nThe SPY001 Phase 1 trial is a first-in-human, randomized, double-blind, placebo-controlled trial designed to evaluate safety and PK of SPY001 in healthy volunteers. To date, the trial has enrolled 56 healthy adult participants into five single-ascending dose (SAD) and two multiple-ascending dose (MAD) cohorts. Doses of SPY001 evaluated in the trial included single doses of 100 mg SC, 300 mg SC, 600 mg SC, 1,000 mg SC, and 1,000 mg IV and multiple doses of 300 mg SC and 600 mg IV. Findings from the interim SAD and MAD portions of the Phase 1 trial are as follows:\n\nSafety – well-tolerated across all dose groups \n\nSingle doses of SPY001 up to 1,000 mg and multiple doses of 600 mg were well tolerated with a favorable safety profile consistent with existing third-party data of the anti-α4β7 class\nThe most common (i.e., occurring in more than one subject) treatment-emergent adverse events (\"TEAEs\") were headache and nasopharyngitis.\nThere were no Grade 2 or above TEAEs or serious adverse events (\"SAEs\"). No AEs led to trial discontinuation\n\nPK – meaningfully differentiated profile relative to vedolizumab\n\nHalf-life estimate is >90 days in the 300mg SC cohort and >100 days in the 600mg SC cohort, ~4-fold greater than vedolizumab's 25-day human half-life\n     \nSPY001 half-life supports potential for maintenance dosing via a single subcutaneous injection on a Q3M and Q6M basis using a high-concentration, citrate-free formulation\n\nDose-proportionality and limited intrasubject variability observed across key parameters (e.g., Cmax, AUC), support planned Phase 2 induction dosing to evaluate exposures of SPY001 in 4th quartile of vedolizumab's exposures to potentially achieve greater clinical remission rates and/or more rapid clinical effect\nNo apparent impact of anti-drug antibodies observed on pharmacokinetic exposures\n\nPD – complete saturation of α4β7 receptor occupancy to latest time point available\n\nSingle 300 mg dose of SPY001 saturated α4β7 receptor occupancy up to Day 57 (longest follow-up available with pharmacodynamic data)\nExploratory immunophenotyping in progress, expected to be shared at upcoming academic conferences\n\n\nSpyre expects to share data from additional cohorts and longer follow-up from existing cohorts at future medical meetings.\nPlatform Phase 2 trial in Ulcerative Colitis\nPending regulatory feedback, Spyre plans to advance SPY001 into a double-blind, randomized, placebo-controlled, Phase 2 platform trial with a master protocol in patients with moderately-to-severely active ulcerative colitis. The platform trial is designed to efficiently evaluate each of Spyre's monotherapy and combination therapies against a common placebo control. The trial is also intended to evaluate the contribution of each monotherapy component to the safety and efficacy of Spyre's combination therapies.\nThis Phase 2 ulcerative colitis trial is expected to initiate in mid-2025 with SPY001 and placebo arms, with SPY002, SPY003, and combination arms to be added following clinical data, nonclinical data, and regulatory feedback. The trial is expected to enroll approximately 500 subjects across treatment arms and consist of a 12-week, placebo-controlled induction period followed by a 38-week maintenance period.\nUpdated portfolio guidance for maintenance dosing\nGiven the PK results of SPY001, the Company is updating its guidance for maintenance dosing across the portfolio to Q3M-Q6M for monotherapies and combinations. Updated guidance highlights Spyre's unique ability to target a product profile with potentially best-in-indication efficacy and convenience.\nConference Call and Webcast\nSpyre will host a conference call and webcast today, November 12, 2024, at 8:00 a.m. ET to discuss the SPY001 Phase 1 interim results. A live webcast of the call will be available on the Investor Relations website at https://ir.spyre.com/events-and-presentations. The webcast will be made available for replay on the company's website following completion of the event.\nAbout SPY001\nSPY001 is an investigational novel, extended half-life monoclonal antibody targeting α4β7 for the potential treatment of IBD. IBD is a chronic condition characterized by inflammation in the gastrointestinal tract and encompasses two main disorders: ulcerative colitis and Crohn's disease. In the United States, it is estimated that approximately 2.4 million individuals currently have IBD. SPY001 targets the same epitope as vedolizumab and demonstrates equivalent potency and selectivity as vedolizumab in head-to-head preclinical studies. Interim data from a Phase 1 trial demonstrated that SPY001 was well tolerated and exhibited a human half-life of >90 days, a ~4-fold increase relative to vedolizumab. This half-life supports potential for both Q3M and Q6M SC maintenance dosing in a single autoinjector compared to vedolizumab's Q2W SC profile. Based on initial Phase 1 clinical data, the company plans to initiate a Phase 2 platform trial in ulcerative colitis in mid-2025.\nAbout Spyre Therapeutics\nSpyre Therapeutics is a clinical-stage biotechnology company that aims to create next-generation of inflammatory bowel disease (IBD) products by combining best-in-class antibody engineering, rational therapeutic combinations, and precision medicine approaches. Spyre's pipeline includes investigational extended half-life antibodies targeting α4β7, TL1A, and IL-23.\nFor more information, please visit http://spyre.com. \nForward-Looking Statements\nThis press release contains \"forward-looking\" statements within the meaning of the safe harbor provisions of the U.S. Private Securities Litigation Reform Act of 1995.
