IRVINE, Calif., Aug. 08, 2024 (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 second quarter ended June 30, 2024, and provided business updates.

“This quarter, with the BOND-003 monotherapy data presented at AUA, and the CORE-001 combination data presented at ASCO and subsequently published in Nature Medicine, we affirmed the potential for cretostimogene, our novel oncolytic immunotherapy candidate, to be used as a bladder-sparing backbone therapy for NMIBC,” said Arthur Kuan, Chairman & Chief Executive Officer of CG Oncology. “We demonstrated our commitment to bladder cancer patients by initiating our Expanded Access Program in June, and we’re encouraged by the strong enrollment that we’ve seen to date. Additionally, we strengthened our team across key functions to ensure that we have the optimal organizational structure for this stage of our growth. We look forward to sharing primary results from our BOND-003 registrational study of cretostimogene monotherapy later this year, and progressing toward submitting our Biologics License Application.”

Corporate Highlights

• Presented Positive Final Results from CORE-001 Phase 2 Clinical Trial of Cretostimogene in Combination with Pembrolizumab in BCG-Unresponsive HR-NMIBC at ASCO 2024. In June, the Company presented positive final results from its CORE-001 Phase 2 study of cretostimogene grenadenorepvec in combination with pembrolizumab in BCG-Unresponsive HR-NMIBC at ASCO 2024, showing a 54% CR rate at the 24-month landmark and meeting the primary endpoint of the study.
  • As of the data cutoff on February 5, 2024, the CR rate in the intention-to-treat (ITT) population at 12-months and any time, was 57% (20/35) (95% confidence interval [CI], 40-73%) and 83% (29/35) (95% CI, 70-95%), respectively. As of May 17, 2024, the CR rate in the ITT population at 24 months was 54% (19/35) (95% CI, 37-71%).
  • Of the patients in a CR at 12 months, 95% of patients (19/20) maintained a CR for another 12 months.
  • Progression-free survival (PFS) at 24 months is 100% with no patients progressing to muscle invasive cancer or metastatic disease.

The results were subsequently published in Nature Medicine. The CORE-001 Phase 2 trial was conducted in collaboration with Merck Sharp & Dohme LLC, a subsidiary of Merck & Co., Inc., Rahway, NJ, USA.

• Cretostimogene Monotherapy Demonstrated 75.2% CR Rate at Any Time in BCG-Unresponsive HR-NMIBC. In May, at AUA in the paradigm-shifting, practice-changing clinical trials in urology session, the Company announced data from the BOND-003 Phase 3, single arm, open label, registrational study evaluating the efficacy and safety of cretostimogene monotherapy in patients with HR-NMIBC unresponsive to BCG, which showed that 75.2% of patients (79 out of 105 [95% CI, 65-83]) achieved a CR at any time, as of the cutoff date on April 1, 2024. There were no Grade 3 or greater adverse effects and no treatment related discontinuations
• Initiated Expanded Access Program for Cretostimogene Grenadenorepvec. In June, the Company announced that it has initiated an expanded access program (EAP) for cretostimogene grenadenorepvec in the U.S. for patients with NMIBC who are unresponsive to BCG and meet certain program eligibility criteria. The first patient has been dosed in the EAP and enrollment in the study is ongoing.

Anticipated Next Milestones

• BOND-003 (BCG-Unresponsive, HR-NMIBC): Primary results from the Phase 3 clinical trial of cretostimogene monotherapy by the end of 2024.
  

Second Quarter 2024 Financial Highlights

• Cash Position: Cash and cash equivalents and marketable securities as of June 30, 2024, were $552.9 million, compared with $566.5 million as of March 31, 2024. Based on cash, cash equivalents and marketable securities as of June 30, 2024, and current operating plans, the Company expects its cash runway to be sufficient to fund operations through 2027.
• Research and Development (R&D) Expenses: R&D expenses for the second quarter ended June 30, 2024 were $18.5 million compared with $9.8 million for the second quarter ended June 30, 2023 due to the progression of and increase in clinical trials expense supporting the development of cretostimogene in multiple indications.
• General and Administrative (G&A) Expenses: G&A expenses for the second quarter ended June 30, 2024 were $7.5 million compared with $2.5 million for the second quarter ended June 30, 2023.
