Bicycle Therapeutics plc (NASDAQ:BCYC), a biotechnology company pioneering a new and differentiated class of therapeutics based on its proprietary bicyclic peptide (Bicycle®) technology, today announced that an article highlighting preclinical data from BT8009, a Nectin-4 targeting Bicycle Toxin Conjugate, was published in the Journal of Medicinal Chemistry. The article, titled “Discovery of BT8009: a Nectin-4 Targeting Bicycle® Toxin Conjugate for the Treatment of Cancer” is available at the publications section of the Bicycle website at this link.

“The pre-clinical data published in the Journal of Medicinal Chemistry describe the discovery of our clinical-stage Bicycle Toxin Conjugate candidate targeting Nectin-4 expressing tumors,” said Nicholas Keen, Ph.D., Chief Scientific Officer of Bicycle Therapeutics. “Together with our study published recently in Molecular Cancer Therapeutics, these articles describe the preclinical work supporting the development of BT8009, which we are currently evaluating in a Phase I/II clinical trial across a number of solid tumor cancers. Nectin-4 is a validated tumor antigen target and we are excited to develop a novel approach to Nectin-4 expressing tumors.”

About Bicycle Therapeutics

Bicycle Therapeutics (NASDAQ: BCYC) is a clinical-stage biopharmaceutical company developing a novel class of medicines, referred to as Bicycles, for diseases that are underserved by existing therapeutics. Bicycles 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 Bicycles attractive candidates for drug development. Bicycle is evaluating BT5528, a second-generation Bicycle Toxin Conjugate (BTC®) targeting EphA2; BT8009, a second-generation BTC targeting Nectin-4, a well-validated tumor antigen; and BT7480, a Bicycle TICA® targeting Nectin-4 and agonizing CD137, in company-sponsored Phase I/II trials. In addition, BT1718, a BTC that targets MT1-MMP, is being investigated in an ongoing Phase I/IIa clinical trial sponsored by the Cancer Research UK Centre for Drug Development. Bicycle is headquartered in Cambridge, UK, with many key functions and members of its leadership team located in Lexington, MA. For more information, visit bicycletherapeutics.com.
