Item 8.01 Other Events.

On May 3, 2024, CG Oncology, Inc. (the Company) announced that interim data from the Phase 3 BOND-003 study evaluating the efficacy and safety of cretostimogene monotherapy in patients with high-risk Non-Muscle-Invasive Bladder Cancer (NMIBC) unresponsive to Bacillus Calmette-Guerin (BCG), showed that 75.2% of patients (79 out of 105 [95% Confidence Interval (CI), 65-83]) achieved a complete response (CR) at any time, as of the cutoff date of April 1, 2024. These data were featured today at the Paradigm-Shifting, Practice-Changing Clinical Trials in Urology Plenary Session as an Oral Presentation (Abstract #24-11358) by Dr. Mark D. Tyson, urologic oncologist at Mayo Clinic, at the 2024 American Urological Association Annual Meeting, in San Antonio, TX. In addition, cretostimogene has shown durable responses over time with 29 patients maintaining a CR for 12 months or more, pending evaluation and assessment of ongoing responses in 22 additional patients as of the data cutoff. Median duration of response (DOR) was not reached as of the cutoff date. In addition, 53.8% of repeat induction patients converted to a CR as of the data cutoff. 92.4% cystectomy-free-survival was observed and none of the patients with a CR had undergone radical cystectomy or showed nodal or metastatic progression.

BOND-003 is a single-arm, Phase 3, monotherapy clinical trial for the treatment of patients with high-risk BCG-unresponsive NMIBC with carcinoma in-situ (CIS) with or without Ta or T1 papillary tumors. The fully enrolled global trial with a total of 112 patients is currently ongoing in North America and the Asia-Pacific region. The primary endpoint of the study is CR at any time, with DOR measured as a secondary endpoint. The highly pre-treated study population includes patients with prior intravesical chemotherapy and systemic immunotherapy. The Company expects to report topline data from BOND-003 by the end of 2024.

Cretostimogene has been generally well-tolerated in the trial as of the safety cutoff date of January 31, 2024. There were no Grade 3 or higher treatment-related adverse events (TRAEs) or deaths reported, and two patients (1.8%) had serious TRAEs (Grade 2), cystitis noninfective and clot retention. No treatment-related discontinuation of cretostimogene was observed. 94.5% of patients completed all expected treatments, and all patients that completed their expected treatments had a 100% successful instillation rate. TRAEs occurred in 70 patients (62.5% percent). The most common TRAEs (≥10%) were bladder spasm, pollakiuria, dysuria, micturition urgency, and hematuria, as of the safety cutoff date.

Forward Looking Statements

The Company cautions you that statements contained in this report regarding matters that are not historical facts are forward-looking statements. The forward-looking statements are based on our current beliefs and expectations and include, but are not limited to, the potential therapeutic benefits of cretostimogene for high-risk and intermediate-risk NMIBC patients and the expected timing of topline data for the BOND-003 trial. Actual results may differ from those set forth in this report due to the risks and uncertainties inherent in our business, including, without limitation: interim results of a clinical trial are not necessarily indicative of final results and one or more of the clinical outcomes may materially change as patient enrollment continues, following more comprehensive reviews of the data, and as more patient data becomes available; potential delays in the commencement, enrollment, data readout and completion of clinical trials, including the BOND-003 trials our dependence on third parties in connection with manufacturing, shipping and clinical and preclinical testing; results from earlier clinical trials and preclinical studies not necessarily being predictive of future results; unexpected adverse side effects or inadequate efficacy of cretostimogene that may limit its development, regulatory approval, and/or commercialization; and other risks described in our filings with the SEC, including under the heading “Risk Factors” in our annual report on Form 10-K and any subsequent filings with the SEC. You are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date hereof, and we undertake no obligation to update such statements to reflect events that occur or circumstances that exist after the date hereof.
