PRINCETON - Bristol Myers Squibb (NYSE: BMY) today announced the first presentation of results from the Phase 3 CheckMate -9LA trial, which demonstrated a statistically significant and clinically meaningful survival benefit with Opdivo (nivolumab) plus Yervoy (ipilimumab), given concomitantly with two cycles of chemotherapy, for the first-line treatment of metastatic non-small cell lung cancer (NSCLC).

The study met both its primary and key secondary endpoints, demonstrating superior overall survival (OS), progression-free survival (PFS) and overall response rate (ORR) for the dual immunotherapy plus chemotherapy combination versus chemotherapy alone.

At a prespecified interim analysis for the primary endpoint of OS, Opdivo plus Yervoy combined with two cycles of chemotherapy reduced the risk of death by 31% compared to chemotherapy alone at a minimum follow-up of 8.1 months [Hazard Ratio (HR): 0.69, 96.71% Confidence Interval (CI): 0.55 to 0.87; p=0.0006]. Additionally, with longer follow-up (minimum of 12.7 months), the combination continued to show sustained OS improvements over chemotherapy alone (median OS of 15.6 months versus 10.9 months, respectively [HR: 0.66, 95% CI: 0.55 to 0.80]). The clinical benefit was observed across all efficacy measures in key population subgroups, including by PD-L1 expression and tumor histology (squamous or non-squamous).

The safety profile of Opdivo (360 mg every three weeks) plus Yervoy (1 mg/kg every six weeks) and two cycles of chemotherapy was reflective of the known safety profiles of the immunotherapy and chemotherapy components in first-line NSCLC. These results (Abstract #9501) will be featured in an oral session at the American Society of Clinical Oncology (ASCO) Annual Meeting 2020, held virtually, from May 29-31.

'The nivolumab plus ipilimumab combination has been shown to increase survival in patients with first-line non-small cell lung cancer, and adding a limited course of chemotherapy may help mitigate the risk of early disease progression,' said Martin Reck, M.D., Ph.D., CheckMate -9LA study investigator, Lung Clinic Grosshansdorf, German Center of Lung Research. 'With these results from CheckMate -9LA, we now have evidence that this dual immunotherapy combination, when administered concomitantly with two cycles of chemotherapy, provides a survival benefit in this setting - a benefit that was observed early and sustained at one year of follow-up across key subgroups of patients. As the data become more mature, I see the potential for an improving survival benefit over time.'

With a minimum follow-up of 12.7 months, Opdivo plus Yervoy with limited chemotherapy improved OS regardless of PD-L1 expression levels, reducing the risk of death by 38% in patients with PD-L1
