Distant metastasis-free survival, a secondary endpoint, was also significantly improved versus placebo (HR=0.76 [95.8% CI: 0.64-0.92; p=0.002]) and had five-year DMFS rates of 48.3% and 38.9% in the Yervoy and placebo groups, respectively.
In a recent multi-institutional clinical trial, 71% of patients who received the immunotherapy drug pembrolizumab, an anti-PD-1 immune checkpoint inhibitor, before surgery had no detectable cancer remaining at the time of surgery.
