IRVINE, Calif., September 9, 2021 – CG Oncology, Inc. today announced a clinical trial collaboration to evaluate the safety and efficacy of CG0070, an oncolytic immunotherapy, in combination with OPDIVO® (nivolumab), Bristol Myers Squibb’s anti-PD-1 therapy, for the treatment of metastatic urothelial cancer in a Phase 1/2 clinical study.

CG0070, CG Oncology’s lead immuno-oncology candidate, is in an ongoing Phase 3 monotherapy study and has been administered in over 100 patients to date for the treatment of high-risk, non-muscle invasive bladder cancer (NMIBC). CG0070 is based on a modified adenovirus type 5 backbone that contains a cancer-selective promoter and a GM-CSF transgene, destroying various cancer cells, including bladder tumor cells, through their defective retinoblastoma (Rb) pathway.

“We are excited to initiate this important clinical trial with our lead oncolytic immunotherapy, CG0070, in combination with OPDIVO in metastatic urothelial cancer,” said Arthur Kuan, CEO of CG Oncology. “The clinical results to date for CG0070 make it a potential promising agent in bladder cancer and other tumor types, as monotherapy or in combination with immune checkpoint inhibitors.”

CG Oncology will sponsor the study and Bristol Myers Squibb will provide nivolumab. Additional details of the collaboration were not disclosed.

OPDIVO® is a trademark of Bristol-Myers Squibb Company.
