• Program intended to facilitate CMC development for selected therapies with expedited clinical development timeframes to help patients get access sooner

CAMBRIDGE, England & BOSTON / Oct 19, 2023 / Business Wire / Bicycle Therapeutics (Nasdaq: BCYC), a biotechnology company pioneering a new and differentiated class of therapeutics based on its proprietary bicyclic peptide (Bicycle®) technology, today announced that BT8009, the company’s lead investigational therapy in development to treat metastatic bladder (urothelial) cancer, has been selected to participate in the Chemistry, Manufacturing and Controls (CMC) Development and Readiness Pilot (CDRP) Program recently launched by the U.S. Food and Drug Administration (FDA). BT8009 is one of up to nine products selected for the first year of the CDRP Program, which the FDA created to facilitate CMC development for therapies with expedited clinical development timeframes based on the anticipated clinical benefits of earlier patient access to the therapy. Through the CDRP Program, Bicycle Therapeutics plans to work closely with the FDA to facilitate CMC development and expedite commercial manufacturing readiness of BT8009.

“We are honored to participate in the inaugural cohort of the FDA’s CDRP Program,” said Mike Hannay, D.Sc., FRPharmS, senior vice president and head of CMC at Bicycle Therapeutics. “We look forward to working closely with the FDA to ensure the commercial manufacturing readiness for BT8009 keeps pace with its expedited clinical development. We welcome the guidance we will receive through more frequent and dedicated CMC discussions with the FDA, and in turn we hope the agency will become more familiar with our novel Bicycle® technology and its sophisticated manufacturing process.”

“At Bicycle Therapeutics, we are pioneering an entirely new class of drugs with the goal of treating cancer and many other diseases. We believe BT8009 has the potential to be a transformative therapy for patients with metastatic bladder cancer, which is underscored by its selection for the FDA’s CDRP Program in addition to its Fast Track designation and recently announced expedited development plan and registrational pathway,” said CEO Kevin Lee, Ph.D. “On behalf of our entire team, I would like to thank the FDA for their continued collaboration as we work with urgency to develop and deliver this promising therapy to patients.”

In September, Bicycle Therapeutics announced its plan to expedite development of BT8009 in metastatic bladder cancer following alignment with the FDA on the therapy’s Phase 2/3 registrational trial, called Duravelo-2. The innovative trial design allows for the potential accelerated approval of BT8009 in untreated (first-line) and previously treated (second-line plus) metastatic bladder cancer. The company plans to initiate the Duravelo-2 trial in the first quarter of 2024.

About BT8009

BT8009 is an investigational Bicycle Toxin Conjugate (BTC™) targeting Nectin-4, a well-validated tumor antigen with elevated levels of expression in multiple tumor types, including bladder (urothelial) cancer. It is currently being evaluated in a Phase 1/2 clinical trial enrolling patients with Nectin-4 expressing advanced solid tumors. BT8009 will be evaluated in the Phase 2/3 Duravelo-2 trial, a global, multi-center, adaptive study designed to assess the safety and efficacy of the therapy for metastatic bladder cancer.

About Bicycle Therapeutics

Bicycle Therapeutics is a clinical-stage biopharmaceutical company developing a novel class of medicines, referred to as Bicycles, for diseases that are underserved by existing therapeutics. Bicycles 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 Bicycles attractive candidates for drug development. The company is evaluating BT5528, a Bicycle Toxin Conjugate (BTC™) targeting EphA2; BT8009, a BTC targeting Nectin-4, a well-validated tumor antigen; and BT7480, a Bicycle TICA™ targeting Nectin-4 and agonizing CD137, in company-sponsored Phase 1/2 trials. In addition, BT1718, a BTC that targets MT1-MMP, is being investigated in an ongoing Phase 1/2a clinical trial sponsored by the Cancer Research UK Centre for Drug Development. 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.
