Summary

This phase 2 study tested a new drug, FLX475, combined with the immunotherapy pembrolizumab (Keytruda) in 20 people with advanced or metastatic stomach cancer. The goal was to see if the combination could shrink tumors in patients who had already tried other treatments. The study included two groups based on whether the cancer was linked to the Epstein-Barr virus.
