"We are thrilled to welcome Roger and Hervé to our Board of Directors as we make strong progress across our pipeline and anticipate numerous upcoming milestones. As prominent leaders in oncology research, drug development and commercialization who have delivered many transformative cancer medicines to patients, Roger and Hervé will add valuable perspectives and expertise," said Bicycle Therapeutics CEO Kevin Lee, Ph.D. "Together, with our entire board of accomplished global oncology leaders and our dedicated team, we are executing on our strategy to develop next-generation targeted therapies with the potential to help patients not only live longer but also live well."

The new Board members are as follows:

Previously, he was interim chief oncology officer and chief development officer of Pfizer Oncology. Dr. Dansey also served as chief medical officer and president of research and development at Seagen prior to Pfizer's acquisition of the company. Earlier in his career, he held senior leadership positions at Merck, Gilead Sciences and Amgen. Dr. Dansey played a key role in the development and approvals of numerous important cancer therapies, including Keytruda<sup>®</sup> (pembrolizumab), Xgeva<sup>®</sup>/Prolia<sup>®</sup> (denosumab), Zydelig<sup>®</sup> (idelalisib), Adcetris<sup>®</sup> (brentuximab vedotin), Padcev<sup>®</sup> (enfortumab vedotin), Tivdak<sup>®</sup> (tisotumab vedotin) and Tukysa<sup>®</sup> (tucatinib). He holds an M.D. from the University of Witwatersrand in Johannesburg, South Africa, and before joining industry, he was an associate professor of hematology/oncology at the Karmanos Cancer Institute in Detroit.

**Hervé Hoppenot** is an advisor to the CEO and serves on the Board of Directors of Incyte, after serving 11 years as the company's chairman and CEO.

**About Bicycle Therapeutics**

Bicycle Therapeutics is a clinical-stage pharmaceutical company developing a novel class of medicines, referred to as Bicycle<sup>®</sup> 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 zelenectide pevedotin (formerly BT8009), a Bicycle<sup>®</sup> Drug Conjugate (BDC<sup>®</sup>) targeting Nectin-4, a well-validated tumor antigen; BT5528, a BDC molecule targeting EphA2, a historically undruggable target; and BT7480, a Bicycle Tumor-Targeted Immune Cell Agonist<sup>®</sup> (Bicycle TICA<sup>®</sup>) targeting Nectin-4 and agonizing CD137, in company-sponsored clinical trials. Additionally, the company is developing Bicycle<sup>®</sup> Radioconjugates (BRC<sup>®</sup>) for radiopharmaceutical use and, through various partnerships, is exploring the use of Bicycle<sup>®</sup> technology to develop therapies for diseases beyond oncology.

Bicycle Therapeutics is headquartered in Cambridge, UK, with many key functions and members of its leadership team located in Cambridge, Mass. For more information, visit <u>bicycletherapeutics.com</u>.
