CG Oncology, Inc. CGON

We are a late-stage clinical biopharmaceutical company focused on developing and commercializing cretostimogene grenadenorepvec (cretostimogene), an investigational oncolytic immunotherapy with a dual mechanism of action designed both to eliminate cancer cells directly by selective replication and indirectly by activating an anti-tumor immune response, as a potential backbone therapy in a broad range of patients afflicted with bladder cancer. Cretostimogene is currently in clinical development for the treatment of patients with high-risk and intermediate-risk non-muscle invasive bladder cancer (NMIBC), which potentially represents up to 150,000 addressable patients.

We are evaluating the safety and efficacy of cretostimogene as a monotherapy in BOND-003 Cohort C, our ongoing Phase 3 clinical trial in high-risk Bacillus Calmette-Guérin (BCG)-unresponsive NMIBC with carcinoma in situ (CIS), with or without Ta/T1 disease. Given the limitations of currently approved therapies, the next course of treatment for these patients with BCG-unresponsive tumors is radical cystectomy, which is the complete removal of the bladder. This surgery carries a significant social, functional and emotional burden for patients. As such, there is a significant unmet need for effective bladder-sparing treatments. We have completed enrollment for this cohort and reported potentially best-in-disease data in September 2025. This trial served as the basis for our Biologics License Application (BLA) submission for our initial indication to the U.S. Food and Drug Administration (FDA), which we initiated in the fourth quarter of 2025 and expect to complete in 2026. Cretostimogene has received both Fast Track and Breakthrough Therapy designations from the FDA for the treatment of high-risk BCG-unresponsive NMIBC with CIS with or without Ta or T1 papillary tumors. Additionally, in April 2024, we initiated BOND-003 Cohort P, an exploratory study evaluating cretostimogene monotherapy in high-risk BCG-unresponsive NMIBC with only Ta/T1 disease. Initial data from this Cohort was reported at the 2025 AUA Annual Meeting, with potentially best-in-disease data reported at the Society of Urologic Oncology (SUO) 26th Annual Meeting in December 2025. Based on internal research derived from the National Cancer Institute Surveillance, Epidemiology, and End Results Program's (NIH SEER) database, secondary claims data analytics and management assumptions, the high-risk BCG-unresponsive NMIBC segment may represent up to 25,000 addressable patients.
