WALTHAM, Mass. - Spyre Therapeutics, Inc. (NASDAQ: SYRE), a biotechnology firm focusing on inflammatory bowel disease (IBD) treatments, reported favorable interim Phase 1 data for its monoclonal antibody, SPY001. The company announced today that SPY001, targeting the α4β7 receptor, was well tolerated in trials with a safety profile consistent with its class. The pharmacokinetic data suggests a half-life over 90 days, potentially enabling less frequent dosing.
The Phase 1 trial, which included 56 healthy adult participants, assessed the safety and pharmacokinetics of SPY001. Results indicated that single and multiple doses up to 1000 mg and 600 mg, respectively, were well-tolerated with no serious adverse events reported. The most common side effects were headache and nasopharyngitis. The pharmacodynamic data showed complete saturation of the α4β7 receptor for up to 12 weeks with a single low dose.
These findings support the potential for SPY001 to offer improved or accelerated efficacy compared to existing treatments and to serve as a backbone for combination therapies in IBD. Spyre plans to initiate a Phase 2 trial in mid-2025, which will include SPY001 and other investigational therapies SPY002 and SPY003, under a single master protocol.
Cameron Turtle, CEO of Spyre, expressed optimism about the Phase 2 trials, highlighting the potential of SPY001 as a differentiated monotherapy and a cornerstone for combination therapies in IBD. The company aims to update its guidance for maintenance dosing across its portfolio to every three to six months for monotherapies and combinations, based on the Phase 1 results.
The upcoming Phase 2 trial will target patients with moderately-to-severely active ulcerative colitis, aiming to enroll around 500 subjects. The trial structure is designed to efficiently evaluate the safety and efficacy of Spyre's therapies.
SPY001 is an investigational drug targeting the same epitope as vedolizumab but with a significantly extended half-life, which could mean less frequent dosing for patients. The company's focus is on creating next-generation IBD products by leveraging antibody engineering, therapeutic combinations, and precision medicine.
