BMS Reports Positive Opdivo plus Yervoy Data
Bristol Myers Squibb says data from the Phase 3 CheckMate-9DW trial evaluating the dual immunotherapy combination of Opdivo (nivolumab) plus Yervoy (ipilimumab) compared to investigator’s choice (lenvatinib or sorafenib) as a first-line treatment for patients with unresectable hepatocellular carcinoma (HCC) showed that the combination had a statistically significant and clinically meaningful improvement in the primary endpoint of overall survival (OS). The company says “Median OS was 23.7 months (95% CI: 18.8–29.4) for Opdivo plus Yervoy compared to 20.6 months (95% CI: 17.5–22.5) with lenvatinib or sorafenib (HR: 0.79 (0.65–0.96); p = 0.018).”
The data also showed, Bristol Myers says, a statistically significant improvement in the key secondary endpoint of objective response rate (ORR), which was 36% for the combination treatment compared to 13% with lenvatinib or sorafenib. And there was a higher complete response rate of 7% for Opdivo plus Yervoy compared with 2% for those taking lenvatinib or sorafenib, it adds.
Additionally, the safety profile for the combination remained consistent with previously reported data and was manageable with established protocols, according to Bristol Myers Squibb. “Treatment-related adverse events (TRAEs) of any grade were reported in 84% of patients with Opdivo plus Yervoy and 91% in patients with lenvatinib or sorafenib,” it says.
