This study compares the drug Pembrolizumab against the investigator's choice of standard chemotherapy (paclitaxel, docetaxel, or irinotecan) in patients with advanced esophageal or esophagogastric junction cancer that has progressed after first-line therapy. Adults aged 18 and over with metastatic or unresectable disease who have had one prior line of standard therapy may take part. The study was conducted in Phase 3 and has been completed.
