"We continue to execute on our strategy, which is grounded in scientific rigor and focused on fulfilling our mission to develop next-generation precision-guided therapeutics that have the potential to help patients live longer and live well," said Bicycle Therapeutics CEO Kevin Lee, Ph.D. "We are energized by the progress we are making across our pipeline, and with this momentum, we are pleased to welcome our new Research and Innovation Advisory Board members, as well as new Board member Charles Swanton, to further our innovation and strategic growth."

Dr. Lee continued: "As we advance our various pipeline programs that hold strong potential for changing the treatment paradigm for patients with cancer and creating value for shareholders, Bicycle remains committed to disciplined capital allocation. Today we announced organizational streamlining efforts that provide us with operational flexibility to deliver potentially value-generating datasets while strengthening our financial position in uncertain market conditions. Saying goodbye to talented team members is very difficult, and we sincerely thank them for their dedication to our company. We believe Bicycle is strongly positioned to realize our strategic priorities and milestones and look forward to providing key program updates over the second half of this year."

Second Quarter 2025 and Recent Events

Presented additional human imaging data for an early Bicycle Radioconjugate (BRC) molecule targeting MT1-MMP at the American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting 2025. A poster presentation included new data from a second patient who underwent MT1-MMP-PET/CT imaging that build on previously announced data. Altogether, the data continue to validate the potential of MT1-MMP as a novel cancer target and demonstrate the positive properties of BRC molecules for radiopharmaceutical imaging. Imaging data from these two patients are representative of the data generated to date in 12 out of 14 patients with various solid tumors.

Bicycle Therapeutics continues to advance its emerging BRC pipeline, with initial EphA2 human imaging data expected in 2H 2025 and company-sponsored clinical trials planned for 2026.
Presented two abstracts highlighting the development of Bicycle Drug Conjugate (BDC) zelenectide pevedotin for metastatic urothelial cancer (mUC) at the 2025 American Society for Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting. The abstracts outlined previously disclosed topline combination data for zelenectide pevedotin plus pembrolizumab in first-line mUC from the Phase 1/2 Duravelo-1 trial and provided an overview of the ongoing Phase 2/3 Duravelo-2 registrational trial for zelenectide pevedotin in mUC.

Bicycle Therapeutics is on track to provide an update on dose selection from the Duravelo-2 trial and the accelerated approval pathway for zelenectide pevedotin in mUC following a meeting with the U.S. Food and Drug Administration planned for 4Q 2025.
Phase 1/2 Duravelo-4 trial for zelenectide pevedotin in NECTIN4-amplified non-small cell lung cancer (NSCLC) open and actively recruiting patients. Duravelo-4 is Bicycle Therapeutics’ second trial to leverage NECTIN4 gene amplification as a biomarker for patient selection and to expand the development of zelenectide pevedotin for additional solid tumors.

With several trials underway assessing the potential for zelenectide pevedotin to treat mUC, breast cancer and lung cancer, the company has decided to pause the previously announced Phase 1/2 Duravelo-5 trial in multiple tumors.
Expanded Board of Directors with the addition of Charles Swanton, M.D., Ph.D., FRS, FMedSci, FRCP, current chair of Bicycle Therapeutics’ Clinical Advisory Board. Dr. Swanton leads the Cancer Evolution and Genome Instability Laboratory at the Francis Crick Institute. His research focuses on how tumors evolve over space and time, developing an understanding of branching evolutionary histories of solid tumors, processes that drive cancer cell-to-cell variation and the impact of cancer diversity on effective immune surveillance and clinical outcomes. Dr. Swanton is a fellow of the Royal Society, a fellow of the Royal College of Physicians and a fellow of the Academy of Medical Sciences. He completed his M.D. and Ph.D. training at the Imperial Cancer Research Fund Laboratories.

Second Quarter 2025 Financial Results

Cash and cash equivalents were $721.5 million as of June 30, 2025, compared to $879.5 million as of December 31, 2024. The decrease in cash and cash equivalents is primarily due to cash used in operations, including increased cash payments for clinical program activities.
R&D expenses were $71.0 million for the three months ended June 30, 2025, compared to $40.1 million for the three months ended June 30, 2024. The increase in expense of $30.9 million was primarily due to increased clinical program expenses for zelenectide pevedotin development, increased discovery, platform and other expenses, and increased personnel-related costs, offset by decreased clinical program expenses for Bicycle Tumor-Targeted Immune Cell Agonist (Bicycle TICA) molecules as well as higher U.K. R&D tax credits period over period.
General and administrative expenses were $18.5 million for the three months ended June 30, 2025, compared to $15.9 million for the three months ended June 30, 2024. The increase in expense of $2.6 million was primarily due to increased personnel-related costs, as well as increased professional and consulting fees.
Net loss was $79.0 million, or $(1.14) basic and diluted net loss per share, for the three months ended June 30, 2025, compared to net loss of $39.8 million, or $(0.77) basic and diluted net loss per share, for three months ended June 30, 2024.
In recognition of the evolving macroeconomic environment and the importance of preserving capital, Bicycle Therapeutics is implementing a workforce reduction and taking other steps to optimize its operations and extend the company’s expected financial runway. These strategic cost realignment efforts are being implemented to prioritize potentially high-impact, value-generating programs, which include the advancement of zelenectide pevedotin, BT5528, next-generation Bicycle Drug Conjugates and the company’s wholly owned pipeline of Bicycle Radioconjugates. Bicycle Therapeutics anticipates total operational savings of approximately 30% over the course of the financial runway period. These actions are expected to extend the financial runway into 2028 and strengthen the company’s ability to weather continued market uncertainty as it advances clinical programs through key milestones.
