Bristol Myers Squibb today announced that the European Commission (EC) has approved Opdivo (nivolumab) for the treatment of adults with unresectable advanced, recurrent or metastatic esophageal squamous cell carcinoma (ESCC) after prior fluoropyrimidine- and platinum-based combination chemotherapy.

The EC’s decision is based on results from the Phase 3 ATTRACTION-3 trial, a study sponsored by Ono Pharmaceutical Co., Ltd. of Japan, which demonstrated a statistically significant and clinically meaningful improvement in overall survival (OS) in patients who received Opdivo versus chemotherapy. The safety profile for Opdivo was favorable compared with chemotherapy and consistent with previously reported studies of Opdivo in other solid tumors.

“Today’s approval marks a critically important milestone for those living with esophageal squamous cell carcinoma, as this is the first time an immunotherapy treatment option has been approved in the European Union for this patient population,” said Ian M. Waxman, M.D., development lead, gastrointestinal cancers, Bristol Myers Squibb. “We are proud of our work in advancing treatment options for people living with upper gastrointestinal cancers, and we look forward to working with European stakeholders to bring Opdivo to more eligible patients who may benefit.”

In addition to this approval in the EU, Opdivo has been approved in five countries, including the United States and Japan, for the second-line treatment of patients with unresectable advanced, recurrent or metastatic ESCC. Bristol Myers Squibb thanks the patients and investigators involved in the ATTRACTION-3 clinical trial for their important contributions.
