FAILED TRIAL: RELATIVITY-123 Trial Evaluating the Fixed-Dose Combo of Opdivo + Relatlimab in Previously Treated MSS CRC Patients unlikely to meet primary endpoint, to be discontinued
“Metastatic colorectal cancer is a challenging cancer to treat with high unmet needs. Though there have been advances in treating patients with microsatellite instability-high (MSI-H)/deficient mismatch repair (dMMR) colorectal cancers, patients with microsatellite stable (MSS) tumors continue to have limited treatment options in later lines of therapy. While we know immunotherapies have historically demonstrated limited efficacy in MSS colorectal cancers, we had hoped to demonstrate meaningful clinical benefit in this patient population and are disappointed in this outcome,” said Jeffrey Walch, M.D., Ph.D., vice president, global program lead, Bristol Myers Squibb. “We continue to be committed to the development of I-O therapies, including Opdivo (nivolumab) and Yervoy (ipilimumab), in MSI-H/dMMR colorectal cancers, and we thank the investigators, patients, and their loved ones who participated in this trial.”

“Our team’s outstanding execution has enabled us to rapidly advance three programs into the clinic in 2026 and make significant progress in developing next-generation IO, ADC and combination therapies. Together with our partner, Kelun-Biotech, we have achieved seven IND clearances to date, and by mid-2027, we expect more than 2,000
