About Bicycle Therapeutics  

Bicycle Therapeutics is a clinical-stage pharmaceutical company developing a novel class of medicines, referred to as Bicycle® molecules, for diseases that are underserved by existing therapeutics. Bicycle molecules are fully synthetic short peptides constrained with small molecule scaffolds to form two loops that stabilize their structural geometry. This constraint facilitates target binding with high affinity and selectivity, making Bicycle® molecules attractive candidates for drug development. The company is evaluating nuzafatide pevedotin (formerly BT5528), a Bicycle® Drug Conjugate (BDC®) targeting EphA2, a historically undruggable target; a pipeline of Bicycle® Radioconjugates (BRCs) and imaging agents; zelenectide pevedotin (formerly BT8009), a BDC® targeting Nectin-4, a well-validated tumor antigen; and, through various partnerships, the use of Bicycle® technology to develop therapies to treat diseases in a range of therapeutic areas.

Bicycle Therapeutics is headquartered in Cambridge, UK, with many key functions and members of its leadership team located in Lexington, Massachusetts, USA. For more information, visit bicycletherapeutics.com
