Revenue model

1. Collaboration Revenue: Bicycle Therapeutics generates collaboration revenue from partnerships with pharmaceutical companies. In Q4 2025, collaboration revenue increased to $48.0 million from $3.7 million year-over-year, primarily due to recognition of remaining revenue following termination notices from Novartis and Bayer collaborations.
2. Equity Financing: The company has raised significant equity capital through private placements and public offerings to fund clinical development and operations. In May 2024, the company secured $555 million through PIPE financing. Previous offerings include $200 million in July 2023 and $175 million in October 2021.
3. Future Product Revenue: Once regulatory approvals are obtained, the company expects to generate revenue from commercial sales of its Bicycle therapeutics. No products are currently approved for commercial sale.

Core offering

Bicycle Therapeutics develops a proprietary platform of fully synthetic bicyclic peptide molecules called Bicycles that serve as targeted delivery vehicles for precision-guided therapeutics in oncology. The company's pipeline includes Bicycle Drug Conjugates (BDCs) delivering cytotoxic payloads to tumors, Bicycle Radioconjugates (BRCs) delivering targeted alpha therapy using radioisotopes, and Bicycle Tumor-Targeted Immune Cell Agonists (TICAs) activating immune cells at tumor sites. The lead clinical-stage candidates are zelenectide pevedotin (Nectin-4 targeting) and nuzefatide pevedotin (EphA2 targeting) for solid tumor cancers.

Product overview

Bicycle Therapeutics is a clinical-stage biopharmaceutical company developing a novel class of bicyclic peptide-based therapeutics called Bicycle molecules. The core technology platform comprises three main product types: Bicycle Drug Conjugates (BDCs) that deliver cytotoxic payloads to tumors, Bicycle Radioconjugates (BRCs) that deliver targeted alpha therapy using radioisotopes like 212Pb, and Bicycle Tumor-Targeted Immune Cell Agonists (TICAs) that activate immune cells at tumor sites. The company's clinical-stage pipeline includes nuzefatide pevedotin (EphA2-targeting BDC in Phase II for pancreatic cancer) and zelenectide pevedotin (Nectin-4-targeting BDC previously in Phase II for urothelial cancer), along with BT1702 (MT1-MMP-targeting BRC in IND-enabling stage) and imaging agents BIA1701 and BIA5501. The company also develops Bicycle TICA candidates including BT7480 and BT7455, and partners with Ionis Pharmaceuticals on TfR1-based CNS delivery technology.

Partnerships

Eight partnerships are on record, tiered core and minor.

• UK Nuclear Decommissioning Authority (NDA)coreStrategic or Co-development Partner · 16 December 202515-year contract for access to up to 400 tonnes of reprocessed uranium for development of radiopharmaceuticals. The partnership enables extraction of radioisotopes including 228Th and 212Pb for targeted alpha therapy in cancer treatments, supporting Bicycle's wholly owned radiopharmaceutical pipeline.
• UK National Nuclear Laboratory (UKNNL)coreStrategic or Co-development Partner · 16 December 2025Collaboration to extract and process radioisotopes from reprocessed uranium using novel separation processes developed by UKNNL to harvest medical isotopes including lead-212 from spent nuclear fuel for targeted alpha therapy applications.
• SpectronRxcoreStrategic or Co-development Partner · 1 December 2025Development of bespoke 212Pb generators for production of lead-212 radioisotope for Bicycle Radioconjugate cancer therapies. SpectronRx developed the radioisotope generator system used to produce lead-212 from recovered parent material.
• Ionis PharmaceuticalscoreStrategic or Co-development Partner · 1 July 2021Collaboration to explore enablement of nucleic acid delivery into various tissue types using Bicycle's TfR1-based precision guidance technology. Lead asset for cardiomyopathy treatment undergoing Phase 1 clinical trials. Preclinical models demonstrate successful delivery of ASOs and siRNAs to skeletal muscle, cardiac muscle, and CNS for gene knockdown.
• BayerminorStrategic or Co-development PartnerStrategic collaboration where Bicycle utilizes its proprietary phage platform to discover Bicycles to be developed into BRCs, with Bayer responsible for and fully funding all further preclinical and clinical development, manufacturing, and commercialization. Note: Collaboration was terminated in 2025 with remaining revenue recognized.
• DKFZ and University Hospital EssenminorStrategic or Co-development PartnerGerman Cancer Consortium using Bicycle Imaging Agents (BIAs) to generate imaging data for range of oncology targets including MT1-MMP and EphA2, including first-in-human imaging studies in pancreatic cancer patients.
• NovartisminorStrategic or Co-development PartnerPrior collaboration terminated in 2025. Remaining collaboration revenue of approximately $48 million recognized in Q4 2025 following termination notice.
• UK GovernmentminorStrategic or Co-development PartnerUK government invested approximately £20m in research to develop alternative production routes for alpha-emitting radioisotopes, supporting Bicycle's radiopharmaceutical development through the NDA partnership.
