Summary
This study tested a new vaccine (EO2040) made from gut bacteria, combined with the immunotherapy drug nivolumab, in people with colorectal cancer who had signs of remaining disease after standard treatment. The goal was to see if the combination could clear cancer DNA from the blood and prevent the cancer from coming back. However, the trial was stopped early after enrolling only one participant, so no conclusions can be drawn.
