Second Quarter 2024 and Recent Events

• Four abstracts accepted for poster presentation at the European Society for Medical Oncology (ESMO) Congress 2024 being held September 13-17 in Barcelona. Bicycle Therapeutics will present four abstracts containing updated clinical data for zelenectide pevedotin (formerly BT8009) in metastatic urothelial cancer (mUC), BT5528 in advanced solid tumors such as mUC and ovarian, and BT7480 in advanced solid tumors.
  
  In June, the company presented two abstracts at the 2024 American Society for Clinical Oncology (ASCO) Annual Meeting outlining clinical pharmacokinetics of Bicycle^® Toxin Conjugate (BTC^®) molecules zelenectide pevedotin and BT5528 compared to antibody drug conjugate enfortumab vedotin and evaluating the emerging safety profile of both BTC molecules, along with an overview of the company’s ongoing Phase 2/3 Duravelo-2 registrational trial of zelenectide pevedotin in mUC.

Second Quarter 2024 Financial Results

• Cash and cash equivalents were $961.4 million as of June 30, 2024, compared to $526.4 million as of December 31, 2023. The increase in cash and cash equivalents is primarily due to net proceeds from the PIPE financing and share option exercises, offset by cash used in operating activities.
• R&D expenses were $40.1 million for the three months ended June 30, 2024, compared to $39.7 million for the three months ended June 30, 2023. The increase in expense of $0.4 million was primarily due to increased clinical program expenses for zelenectide pevedotin development and increased personnel-related expenses, offset by decreased clinical program expenses for Bicycle TICA^® molecule development, decreased discovery, platform and other expenses and incremental U.K. R&D tax credits.
• General and administrative expenses were $15.9 million for the three months ended June 30, 2024, compared to $14.8 million for the three months ended June 30, 2023. The increase of $1.1 million was primarily due to increased personnel-related costs.
• Net loss was $39.8 million, or $(0.77) basic and diluted net loss per share, for the three months ended June 30, 2024, compared to net loss of $42.6 million or $(1.41) basic and diluted net loss per share, for three months ended June 30, 2023.

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 zelenectide pevedotin (formerly BT8009), a Bicycle^® Toxin Conjugate (BTC^®) targeting Nectin-4, a well-validated tumor antigen; BT5528, a BTC molecule targeting EphA2, a historically undruggable target; and BT7480, a Bicycle Tumor-Targeted Immune Cell Agonist^® (Bicycle TICA^®) targeting Nectin-4 and agonizing CD137, in company-sponsored clinical trials. Additionally, the company is developing Bicycle^® Radio Conjugates (BRC™) for radiopharmaceutical use and, through various partnerships, is exploring the use of Bicycle^® 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 bicycletherapeutics.com.
