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 nuzafatide pevedotin (formerly 5528), a Bicycle® Drug Conjugate (BDC®) targeting EphA2, a historically undruggable target; zelenectide pevedotin (formerly BT8009), a BDC targeting Nectin-4, a well-validated tumor antigen; 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® Radioconjugates (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 Lexington, Massachusetts, USA. For more information, visit bicycletherapeutics.com

Clinical Safety & Scientific Leadership

• You will act as the scientific safety leader for assigned compounds, including radiopharmaceuticals, leading the development and maintenance of their safety profiles throughout the clinical lifecycle.
• You will lead all safety evaluation activities, from First-in-Human studies through to later-stage development, driving the regular review of emerging safety data and safety signal management, and presenting critical findings to senior management and governance bodies.
• You will provide expert safety input into the design of clinical studies, shaping key documents such as protocols, investigator brochures including the Reference Safety Information, and informed consent forms.

Safety Governance & Risk Management

• You will lead the authoring of aggregate safety reports (e.g., DSURs) and drive the development and implementation of Risk Management Plans (RMPs).
• You will oversee our pharmacovigilance vendor partners for your assigned programs, ensuring quality and compliance in case management, and you will lead the development of Safety Management Plans.
• You will provide expert guidance on the medical coding of adverse events and lead the analysis of serious adverse events, including the preparation of analyses of similar events for SUSARs.

Regulatory Strategy & Submissions

• You will lead the preparation of the safety components for major regulatory submissions (e.g., NDAs/MAAs), working in partnership with regulatory affairs and other cross-functional colleagues.
• You will be accountable for authoring strategic safety documents in response to requests from Regulatory Authorities.

Cross-Functional Partnership & Influence

• You will act as the primary safety representative on clinical study teams and serve as the subject matter expert in interactions with external groups such as Safety Monitoring Committees and Independent Data Monitoring Committees.
• You will work in close partnership with the study Medical Monitors and other leaders across Clinical Development, Regulatory, and Quantitative Pharmacology to provide a fully integrated approach to patient safety.

Core Skills & Competencies
