Cetuximab does not enhance the activity of the standard of care for advanced biliary-tract cancer (gemcitabine plus a platinum-based agent), according to the results of a phase II trial published in The Lancet Oncology. In the chemotherapy plus cetuximab group, median progression-free survival was 6.1 months and median overall survival was 11.0 months; in the chemotherapy alone group they were 5.5 months and 12.4 months, respectively.
