Bristol Myers Squibb (NYSE: BMY) announced that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has recommended approval of Opdivo ^® (nivolumab) plus Yervoy ^® (ipilimumab) for the first-line treatment of adult patients with microsatellite instability–high (MSI-H) or mismatch repair deficient (dMMR) unresectable or metastatic colorectal cancer (mCRC). Of significance, the CheckMate -8HW trial results showed reduction in the risk of disease progression or death by 79% (HR: 0.21; 95% CI: 0.14-0.32; p<0.0001) compared to chemotherapy in this patient population. The European Commission (EC), which has the authority to approve medicines for the European Union (EU), will now review the recommendation and make their decision.

“Approximately 5-7% of metastatic colorectal cancer patients have dMMR or MSI-H tumors, and current treatment options often do not provide sufficient benefit,” said Dana Walker, M.D., M.S.C.E., vice president, global program lead, gastrointestinal and genitourinary cancers, Bristol Myers Squibb. “This is the first dual checkpoint inhibitor treatment for first-line metastatic colorectal cancer, delivering a transformative benefit for MSI-H/dMMR patients in this population. We are focused on bringing Opdivo plus Yervoy to these patients in the European Union and look forward to EC’s upcoming decision.”

The positive opinion is based on results from the CheckMate -8HW trial, which were presented at medical congresses earlier this year. These data formed the basis for the Company’s Type II variation application, which was validated by the European Medicines Agency (EMA). In the study, Opdivo plus Yervoy demonstrated a statistically significant and clinically meaningful improvement in the dual primary endpoint of progression-free survival (PFS) compared to the investigator’s choice of chemotherapy as assessed by Blinded Independent Central Review. In addition to the risk of disease progression or death the results noted, the safety profile for the dual immunotherapy combination remained consistent with previously reported data and was manageable with established protocols, with no new safety signals identified.

In October 2024, it was announced that Opdivo plus Yervoy also demonstrated a statistically significant and clinically meaningful improvement in the dual endpoint of PFS per BICR compared to Opdivo monotherapy across all lines of therapy. The study is ongoing to assess various secondary endpoints, including overall survival (OS).

Bristol Myers Squibb thanks the patients and investigators involved in the CheckMate -8HW clinical trial.
