Background Information

The purpose of this study is to see if pembrolizumab in combination with chemotherapy and surgery is more effective than placebo (a look-alike product with no active ingredients) with chemotherapy and surgery. This will be measured by tissue samples that are taken during surgery as well as imaging performed at different time points. The study will test the safety of the study drugs, pembrolizumab in combination with chemotherapy and surgery, and see how well the body handles pembrolizumab compared to placebo in combination with chemotherapy and surgery. The study will help determine if pembrolizumab helps patients have a better quality of life and helps patients live longer.
