IRVINE, Calif., February 27, 2026 (GLOBE NEWSWIRE) -- CG Oncology, Inc. (NASDAQ: CGON) today reported financial results for the fourth quarter and year ended December 31, 2025, and provided business updates.

“In the coming months, we look forward to sharing topline data from PIVOT-006, the first randomized registrational trial to evaluate an investigational therapy in intermediate-risk NMIBC. We believe we have the opportunity to set the new standard in intermediate-risk NMIBC. I am extremely proud of our team for planning, enrolling and executing this important trial in record time. With cretostimogene’s unique best-in-disease profile, we remain laser-focused on advancing a comprehensive strategy designed to support an optimized product label and ensure success across additional indications—positioning cretostimogene as a potential backbone therapy for a broad range of NMIBC patients,” said Arthur Kuan, Chairman & Chief Executive Officer at CG Oncology. “We are also looking forward to sharing results from CORE-008 Cohort CX in high-risk BCG exposed from our first trial evaluating the combination of cretostimogene with gemcitabine in the coming quarter.”

•

Updated timeline for Phase 3 topline data from PIVOT-006 clinical trial evaluating cretostimogene as an adjuvant therapy in intermediate-risk NMIBC. In January 2026, the Company announced an expedited timeline for PIVOT-006, nearly a year ahead of schedule underscoring the excitement for cretostimogene and the significant unmet need in intermediate-risk NMIBC. PIVOT-006 is the first Phase 3 randomized trial in this patient population, encompassing the broadest range of patient types per AUA/SUO Guidelines including HG Ta solitary lesions ≤ 3cm.

Presented Late-Breaking Abstracts at the Society of Urologic Oncology (SUO) 26th Annual Meeting in December 2025. Cretostimogene demonstrated HG-EFS at 3- 6- and 9-months of 95.7%, 84.6% and 80.4%, respectively, in HR BCG UR Ta/T1 disease in BOND-003 Cohort P. CORE-008 Cohort A Data in HR BCG-Naïve NMIBC demonstrates 88% CR and favorable safety.
