Long-term follow-up from a phase Ib trial in newly diagnosed and previously treated patients with advanced melanoma showed that 40 percent of patients were alive three years after starting Keytruda (pembrolizumab), with similar 36-month overall survival rates in both groups.
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.
