About Spyre Therapeutics

Spyre Therapeutics works on early, preclinical research aimed at treating inflammatory bowel disease, covering conditions such as ulcerative colitis and Crohn's disease. Its work centers on antibody-based candidates designed to act on specific biological targets involved in the disease, including one built to bind the a4ß7 integrin and another aimed at tumor necrosis factor-like ligand 1A. The company is best known for pursuing these antibody programs rather than for any product currently available to patients.

Spyre's pipeline extends beyond its lead candidates to include several other antibody therapies, some combining more than one mechanism of action, such as pairing anti-a4ß7 with anti-IL-23 activity, or joining anti-TL1A with anti-IL-23 components. Other candidates target IL-23 alone or use mechanisms described as novel. All of these programs remain in preclinical evaluation, meaning the company's work at this stage is research-driven rather than commercial, with no indication of existing customers or revenue-generating products.

The company was originally incorporated in 2013 under the name Aeglea BioTherapeutics, Inc., adopting the name Spyre Therapeutics, Inc. in November 2023. It is headquartered in Waltham, Massachusetts, and its shares are listed on the NASDAQ under the ticker SYRE.
