Bristol Myers Squibb Presents Results from CheckMate -8HW Analysis Evaluating Opdivo® (nivolumab) plus Yervoy® (ipilimumab) Compared to Opdivo Monotherapy in Patients with Microsatellite Instability-High or Mismatch Repair Deficient Metastatic Colorectal Cancer

Bristol Myers Squibb (NYSE: BMY) today announced results of an analysis from the three-arm Phase 3 CheckMate -8HW trial evaluating Opdivo® (nivolumab) plus Yervoy® (ipilimumab) versus Opdivo monotherapy across all lines of therapy, including first-line, for the treatment of microsatellite instability-high/mismatch repair-deficient (MSI-H/dMMR) metastatic colorectal cancer (mCRC). At a median follow-up of 47 months, Opdivo plus Yervoy demonstrated a statistically significant and clinically meaningful improvement in the dual-primary endpoint of progression-free survival (PFS) as assessed by Blinded Independent Central Review (BICR) versus Opdivo monotherapy (HR 0.62; 95% CI 0.48–0.81; P = 0.0003).

These results will be featured in a late-breaking oral presentation (LBA143) at the American Society of Clinical Oncology (ASCO) Gastrointestinal Cancers Symposium on January 25 at 1:00 p.m. Pacific Time, in San Francisco, California and published the same day in The Lancet.

Previous results from CheckMate -8HW, evaluating Opdivo plus Yervoy versus investigator’s choice of chemotherapy, demonstrated that Opdivo plus Yervoy reduced the risk of disease progression or death by 79%. The results were published in The New England Journal of Medicine and were the basis for a European Commission approval for first-line patients with MSI-H/dMMR mCRC in December 2024.

"The benefit of dual inhibition of PD-1 and CTLA-4 has been well established in Phase 3 trials of Opdivo plus Yervoy across a broad range of tumor types, including in MSI-H/dMMR mCRC compared to chemotherapy," said Dana Walker, M.D., M.S.C.E., vice president, global program lead, late development, oncology, Bristol Myers Squibb. "The results from this analysis of the CheckMate -8HW trial answer affirmatively an important question about whether dual I/O therapy with Opdivo plus Yervoy can also improve outcomes for patients with MSI-H/dMMR mCRC compared with Opdivo alone."
