• Demonstrated continued best-in-disease durability and tolerability in BOND-003 Cohort C with robust 24-month complete response (CR) rate of 41.8% observed for cretostimogene monotherapy in patients with HR NMIBC unresponsive to Bacillus Calmette Guerin (BCG)
• Completed enrollment of PIVOT-006, one of the largest randomized Phase 3 studies in intermediate risk (IR) NMIBC encompassing broadest range of patients per AUA/SUO Guidelines
• Well-positioned to deliver on key milestones with $680.3 million cash and cash equivalents and marketable securities sufficient to fund operations into the first half of 2028

IRVINE, Calif., Nov. 14, 2025 (GLOBE NEWSWIRE) -- CG Oncology, Inc. (NASDAQ: CGON), a late-stage clinical biopharmaceutical company focused on developing and commercializing a potential backbone bladder-sparing therapeutic for patients with bladder cancer, today reported financial results for the third quarter ended September 30, 2025, and provided business updates.

“I am proud of the meaningful progress we have made over the last few months, most notably, the initiation of our BLA submission of cretostimogene for our lead indication of HR BCG-unresponsive NMIBC with CIS with or without Ta/T1 disease. With cretostimogene’s unique profile, we remain committed to advancing a robust clinical, regulatory, and technical strategy designed to support an optimized label and expansion into 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 look forward to sharing additional data from BOND-003 Cohort P and CORE-008 Cohort A before year-end.”

Corporate Highlights

• Initiated BLA submission for cretostimogene monotherapy in HR BCG-unresponsive NMIBC with CIS with or without Ta/T1 disease.  The Company initiated its rolling BLA submission for cretostimogene with complete submission expected in 2026. Cretostimogene has both Fast Track and Breakthrough Therapy Designations which are intended to accelerate the path to U.S. FDA submission.
• Presented Best-in-Disease Durability and Tolerability Data from BOND-003 Cohort C. In September, the Company presented best-in-disease durability and tolerability data on BOND-003 Cohort C showing 12 additional patients with HR BCG-unresponsive NMIBC with CIS with or without Ta/T1 disease were in complete response (CR) at 24 months. The robust 24-month complete response landmark rate of 41.8% (CR rate observed in 46 out of 110 patients) for cretostimogene monotherapy reaffirms the best-in-disease durability, with 90% of 12-month responders remaining disease free at 24 months.  The safety profile remained consistent with no Grade 3 or greater treatment-related adverse events or deaths reported.
• Completed enrollment of PIVOT-006 clinical trial of cretostimogene in IR NMIBC. In September, the Company completed enrollment of PIVOT-006, approximately 10 months ahead of schedule underscoring patients’ and physicians’ interest in cretostimogene and the significant unmet need in IR NMIBC.  PIVOT-006 is one of the largest randomized Phase 3 studies in this patient population and encompasses the broadest range of patient types per AUA/SUO guidelines.
  

Anticipated Upcoming Milestones

• BOND-003 Cohort P (HR BCG-unresponsive NMIBC in Ta/T1 disease without CIS): Topline data from the Phase 3 clinical trial of cretostimogene monotherapy in 4Q’25
• CORE-008 Cohort A (HR BCG-naïve NMIBC with CIS +/- Ta/T1): First results from the Phase 2 clinical trial of cretostimogene monotherapy in 4Q’25
• CORE-008 Cohort CX (HR BCG-exposed NMIBC): Topline data from the Phase 2 clinical trial of the combination of cretostimogene with gemcitabine in 1H’26
• Completion of BLA submission in initial indication, HR BCG-unresponsive NMIBC with CIS with or without Ta/T1 disease, in 2026

Third Quarter 2025 Financial Highlights

• Cash Position: Cash and cash equivalents and marketable securities as of September 30, 2025 were $680.3 million, compared with $661.1 million as of June 30, 2025, which includes net proceeds of approximately $48.7 million from the sale of 1,515,151 shares through the Company’s at-the-market (ATM) facility based on reverse inquiry from an existing, high-quality fund.  Based on current operating plans, the Company expects its existing cash, cash equivalents and marketable securities will be sufficient to fund operations into the first half of 2028.
• Research and Development (R&D) Expenses: R&D expenses for the three months ended September 30, 2025 were $27.9 million compared with $19.6 million for the three months ended September 30, 2024. The increase was primarily due to an increase in clinical trial expenses and an increase in compensation costs due to increased headcount.
• General and Administrative (G&A) Expenses: G&A expenses for the three months ended September 30, 2025 were $23.3 million compared with $8.7 million for the three months ended September 30, 2024. The increase was primarily attributed to an increase in legal expenses and other professional fees and an increase in personnel-related expenses, including compensation costs from increased headcount.
• Net Loss: Net loss was $43.8 million, or ($0.57) per share, for the three months ended September 30, 2025, compared to a net loss of $20.4 million, or ($0.30) per share, for the three months ended September 30, 2024.
