Pembrolizumab (MK-3475) Plus Investigational Agents in Resectable Non-small Cell Lung Cancer (NSCLC) (MK-3475-01E/KEYMAKER-U01)
The main goals are after treatment given before surgery, to measure the number of people who have no signs of cancer cells in tumors and lymph nodes removed during surgery; and to learn about whether the cancer gets smaller or goes away by measuring the number of people with a certain number of living cancer cells in the tumor removed during surgery.
