Summary

This study tests whether adding the experimental drug CTX-009 to standard chemotherapy (paclitaxel) helps adults with advanced bile duct, gallbladder, or ampullary cancer that has worsened after one prior treatment. About 168 participants will be randomly assigned to receive either the combination or chemotherapy alone. The goal is to see if the combination shrinks tumors or delays cancer growth better than chemotherapy alone.
